Douluo Continent: Start from signing in Twins

Chapter 97
After a while, under the leadership of that attendant.

The representatives of all the forces that were summoned this time walked into this big tent one after another, gathered here, and began to get to know each other.

After some introduction.

Tianlin also roughly understands the current situation.

At this moment, except for their accident.

There are a total of four teams who were invited to explore this 'relic'.

They are: Adventurers Association, Soul Master Chamber of Commerce, Imperial Knights, and Spirit Hall...

Needless to say, the Imperial Knights, led by the blond female knight Elena, has a total of thirty elite imperial knights in a squad.Responsible for protecting the safety of the professor, come to explore the ruins to crack the secrets that may be hidden in the ruins.

On the Wuhundian side, the current Saintess Hu Liena led the team, bringing together a Soul Sage elder, a deacon, and ten elite Templar knights.On the surface, he also accepted the entrustment of the lord Viscount to investigate the ruins.However, the real purpose cannot be ascertained...

Then, there was a high-level mercenary group belonging to the Adventurer's Association - [Warhammer Mercenary Group].Led by a tall, bald man named Barrett, there are about 20 people.All of them are good players who hunt outside all the year round and carry out entrusted tasks. Generally, their spirit power is around level [-], and their strength is not weak.

In the end, it was the team made up of the Soul Master Chamber of Commerce.The number is small, only three people.The leader is a middle-aged man who looks very wise and shrewd.It is said that it is a senior appraiser sent by the Soul Master Chamber of Commerce to evaluate the value of various ancient objects in this 'relic'.

In order to facilitate this, the Soul Master Chamber of Commerce purchased those precious ancient items from the lord Viscount at a reasonable price at the first time.

As for Tianlin, there is no need to explain.

Apart from him and Sister Li, there were only the thirty 'no-name' guards who were going to open the way.

……

Soon, after getting to know each other.

The five teams did not delay any longer.

Immediately, under the leadership of the miners assigned by the Viscount Kenny, they entered the main mine on the front of the hillside and stepped into this mysterious ancient "mineral relic".

Originally, Tianlin was going to wait for Tang San and the others... After all, if the tutors from his own academy could come over in time.

With them, it will be much safer if they go down the mine together.

However, at present, these four unexpected mixed elite teams have opened the way.Such a good opportunity, Tian Lin is not willing to miss it.

After all, if these people are allowed to go down first.

Even if the extremely rare Mithril Crystal Soul really exists under the mine vein, it may be taken away by these people.Lin Ke was going to make a trip in vain that day.

Therefore, he decided to act together with these, and go to investigate together first.

……

And just when their mixed team was about to enter the mine vein.

On the other side of the hill, in a hidden cave.

"How is it? Are you all here?" The young man in Chinese clothes asked quietly.

"It's all here!

The Adventurer's Association, the Soul Master Chamber of Commerce, the Imperial Knights, and the Spirit Hall, all the invited people have come!They are preparing to enter the mine. "

"Very good! With so many witnesses. At that time, no one will suspect me of the death of my second sister!

Everyone would only think that the kingdom's second princess died accidentally while exploring this ancient ruins.

And the father and king can handle it too!
In addition, the layout in the mine is all set up? "

"Return to Your Highness, everything is set up! There will be no mistakes!

The escape route has also been reserved.You can evacuate at any time..."

"Very well, let's go. Let's go in!

I can't wait to see the frightened look of my lovely little sister. "A look of pride flashed across the face of the Chinese man, making him look extraordinarily pervasive.

Then, he led a few subordinates and carried a few huge black iron cages, and entered the mine vein from another secret passage.

……

...

At this moment, after entering the mine tunnel.

The team is arranged in sections as a whole, and the front end is led by the mercenary group of the Adventurer's Association.

Then, ten templars, a deacon, and the saint Huliena walked in the middle.

Then, there were the three merchants from the Soul Master Chamber of Commerce, and the lady knight from the Empire [Golden Gui Knights] and her soldier team.

And Tianlin and his party naturally followed slowly at the end...

The main mine road is very wide, fully enough to accommodate their exploration team of nearly a hundred people.

Moreover, there are two kerosene lamps at intervals on both sides of the mine road.It is slowly burning to illuminate the dark mine tunnel.

It can be seen that when the ancients built this mine, they also spent a lot of thought.

……

Gradually, the team is deepening in an orderly manner.

At this moment, in the middle of the team, Hu Liena, the Saintess of the Spirit Hall, muttered in a low voice as she walked: "Brother, this ruin is nothing special! It's just like an ordinary mine...

Why did you deliberately accept this commission and travel all the way to this place to explore this ruin? "

You know, as the seed geniuses cultivated by Wuhundian Academy, there are not many opportunities for them to come out to practice alone like this.

Originally, she wanted to take this opportunity to experience the exciting adventure!

Didn't expect it to be so boring.

"Nana, don't worry. We probably haven't entered the ruins yet.

As for why I deliberately accepted this commission, I can't tell, it should be my intuition!I feel that there is something very important to me in this relic.

So here I am! " Xie Yue explained slowly.

However, in the depths of his eyes, an imperceptible scarlet blood light flashed, which seemed a little strange.

"Really? The treasure that can secretly make you care about it should be very precious! What could it be?" Hu Liena was also curious.

"After going in for a while, you should know.

Nana, pay attention too.Don't be careless!No one knows what dangers will be inside..."

"Okay, okay, I'll pay attention."

While Hu Liena nodded absently, she turned her head frequently, as if she was sizing up someone...

"Nana, what are you looking at?"

"I'm looking at the noble young master at the back of the line, and the girl beside him..."

"Look at them? A dude from a noble family, what's so strange? Nana, do you really have a crush on that boy?"

"What are you talking about? He is several years younger than me. How could I fall in love with such a kid.

It's just that I think he and the girl next to him look familiar... It seems, where have I seen them? "

"Okay, stop being suspicious. Concentrate on exploring, don't be distracted..."

"Okay." Hu Liena withdrew her gaze and suppressed the doubts in her heart.I am going to find a chance to ask the boy in person after a while.

However, at the same time that the saint Hu Liena was secretly watching Tianlin.

In front of the two of them, Mo Duo, the Deacon of the Soul King who was in a daze while walking, also panicked.

A few days ago, he had just returned to the Martial Soul Temple of the Imperial Capital, after reporting the news.

Just once again, was placed here immediately.It is said that he is to do his best to protect the safety of Her Royal Highness during the exploration process.

But, he is just a newly promoted little deacon!The high-ranking soul masters in Wuhun City should catch a lot of things like protecting the saint!
Not to mention the soul king, even the soul emperor, soul saint, etc., there are countless people who are willing to come.

How did it fall on his head?It's weird...

However, what really made Mo Duo extremely flustered was not the beautiful saint behind him.

Instead, it was the brown-haired boy who was at the end of the big team!

A few days ago, I was planted in the hands of that young man, and the painful memory of being defeated by the other party lingered even more.

Although he still didn't know what the identity of the boy was.

However, a superpower with the title Douluo of the Wuhun Temple, the enshrined in the Elder Hall who had never shown up, actually appeared in person, and came to warn himself and Bishop Anthony for the sake of the other party.What an honor!
I'm afraid, even the saint doesn't have this weight!

Therefore, before getting the other party's instructions.The Deacon Mo Duo had no choice but to remain silent, not saying a word.

Don't dare to expose Tianlin's identity, so as not to cause accidents...

……

Meanwhile, the team is last.

While walking, Tianlin was also looking at this ancient mine vein.

The mine is huge, much bigger than the hillside it looks from the outside.

It is estimated that a large part has gone down to the ground.

They have been walking for nearly 10 minutes, but they are still advancing in the endless mine tunnel, with no end in sight.

However, so far, they have not encountered any abnormalities.Everything was similar to that described by Viscount Kenny and the miserable mother and daughter.

This is indeed an ordinary semi-abandoned ancient mithril mine.

However, Tianlin is still skeptical about whether there are any ancient relics under this vein.

After all, it is very possible that the so-called ruins are just lies of the lord...

However, they haven't fully penetrated yet, and they can't say that there is no danger...

Otherwise, the dozens of miners and noble private soldiers would not have disappeared in the mine for no reason.

In fact, in Tianlin's view, the chances of the woman's husband surviving were already very small.

But, since I agreed.Tianlin also decided to search as much as he could.At the very least, being able to bring back some news is better than not knowing life and death...

On the contrary, Tianlin didn't expect it.The silver-haired princess beside him followed in without fear of danger.

Originally, Tian Lin wanted her to stay outside and wait for their return.

However, Xueyin desperately demanded that she must accompany her.In the end, Tianlin let her in together.

After all, in a sense.This Her Royal Highness Princess can be regarded as a big hole card for her side.

If she opens her mouth, the entire team will be invincible!

After all, although there are a lot of people in this patchwork team.But there is no real strong man.

The most powerful one seems to be just that, the temple special envoy soul king that I have met...

"The saintess of the Wuhun Temple, the knights of the empire, a mercenary regiment, and three businessmen... Such a cobbled together team is really interesting!

I don't know, what kind of scene will it show if it is in danger for a while?

Still, there are so many of them.Even if there is danger.

There will be a lot more time left for us to respond, which is an advantage. "Looking at the team next to him, secretly sizing up everyone's expressions and behaviors, Tianlin muttered to himself in a low voice.

"Xiaolin, what are you mumbling about?" Sister Li's voice suddenly sounded from the side.

"nothing……"

"Let me tell you. You are not allowed to flirt with that holy little fox? You are still young, so maybe you won't be fooled by such a little fox!"

"Yeah, I know." Tianlin smiled wryly, feeling that Sister Li cared too much...

Why do you always think that he will be easily deceived by other girls?

I am a good boy who keeps himself clean!
Well……

Even though he's still just a little virgin...

However, at this very moment.

In front of them, the heroic female knight walking in the middle of the team slowed down a little, skipped her own team, and stopped in front of Tianlin.

Talked to him suddenly...

"Professor! Did you find anything?"

Elena pressed her sword hilt, while vigilantly looking around, while discussing with this elderly professor of history.

This Professor Ang Luo, from the Heaven Dou Royal Academy, is already in his sixties this year, although his spirit power is not high, only around thirty.

However, in the study of historiography, it is indeed at its peak and unique.

In the empire, many famous large-scale ancient ruins were researched under his leadership.He has unearthed many rare and ancient relics for the empire and contributed a lot.

However, this time, Professor Ang Luo was on vacation.

After learning of the exploration commission in this kingdom, he took the initiative to ask for an application to come here for inspection.

For this reason, the empire also deliberately arranged an elite knight soldier to escort him...

"There are not many discoveries so far. On the surface, this is a semi-abandoned Mithril mine! The so-called ruins have not yet appeared..."

"Mithril mine? Isn't mithril a rare strategic resource of the empire? As I remember, there seem to be only three mithril mines in the entire empire, right? They seem to be in the hands of the great nobles!
This is actually a mithril mine? "

"My judgment can't be wrong! Besides, there are traces of dirt here. It must have been mined for a few days.

Then, for some reason, it was forced to stop.

Presumably, this is the Lord Viscount.Sending requests around in a hurry, I want to solve the cause of the strange things here! "This wise old professor deduced the truth in an instant. Obviously, he also had a few tricks.

"Hmph! A mithril mine is not something that a remote nobleman can eat! If there is not enough power to protect it, once the news leaks, how can he keep this mithril mine?

It seems that I must also report this news as soon as possible.Let the Marshal and the others make an early decision! "Miss Knight made a serious decision.

As an imperial knight, she naturally didn't want to see such a large mine of treasure being wasted in the hands of a viscount lord.

Naturally, it would be best if such strategic resources could be controlled by the empire.

"Little Linna, don't worry. Think about the things you said after you go out!
Our top priority right now is to fully explore this place.By the way, find out why those innocent workers disappeared! "The old professor comforted slowly, his tone inexplicably reassuring.

"By the way, just now I saw that you were still looking back at the boy behind you from time to time. Why, do you know him?"

"do not know!

It's just that he said he came to the imperial capital, but I have never seen him, which makes me a little strange..." The female knight frowned slightly, and answered with some uncertainty.

"This is not surprising, there are many wealthy families in the imperial capital, and there are also many noble children you have never seen before.

Moreover, being able to directly mobilize the guards in Soto City to guard here, it can be seen that the boy's background is not small.

How about this, take this opportunity and ask him about his position and background!It would be best if he could be won over.After all, our current manpower is not dominant...

There is not only a soul king deacon accompanying the Wuhun Hall, but also a Contra-level elder stationed outside.

In case, some important treasure is found in the ruins, which will cause competition every day!We're going to be in a very bad position..."

This professor An Luo analyzed methodically.Although his head is filled with a lot of historical knowledge, he is also extremely clear and sensitive about these matters of power struggle.

Otherwise, in the vortex of the imperial capital as dark as the abyss, it would be impossible for him to survive until today...

"What? I'm going to win over that dude?" Elena subconsciously refused.She already hated those playboys who were ignorant and could only do their best.

Now, she is naturally very repulsed by asking her to win over that guy.

However, after hesitating for a moment, she decided to give it a try!
Because, she is a knight of the empire and the legitimate daughter of the Franke family.For the sake of the empire and the family, what is a little bit of my own preferences?

Just like that, suppressing the displeasure in his heart, this Knight Elena slowed down.

Leaning towards the brunette boy.

……

"What's the matter?" Tianlin asked directly without courtesy, still acting like a playboy.

Looking at the blond-haired female knight leaning in front of him, Tian Lin was also slightly wary.

That two-meter-long super broad sword is a bit scary to look at!

I don't know how this female knight can swing it?Moreover, why did he suddenly find himself again.

Expose yourself?
"What's your name, which family do you come from?" Elena also asked coldly, she really didn't want to talk to this boy unless necessary.Although, this boy does look handsome, a little handsome.

Tianlin and Sister Li beside him looked at each other, and then answered truthfully: "My surname is Yu, and my name is Tianlin. What's the matter?"

"Are you a soul master too?"

"Hmm. Can't you? Who are you? Are we familiar?"

"You..." Elena was speechless for a moment.Then, he said even more displeasedly: "Elena Franke, a knight of the [Golden Gui Knight Order] of the Empire.

Let me ask you, which family do you belong to? "

"Huh! I won't tell you, what can you do? Use the sword of the empire to cut me?"

"You..." For a moment, Eileen really couldn't help but want to draw out her sword, and slashed this extremely insolent playboy with one sword.

However, in the end, he held back his anger and asked instead: "Since you are also a soul master, what is your martial soul attribute? Can you tell me that?"

"Lightning..."

"Thunder attribute?" Elena asked in surprise.

I was startled in my heart: "The surname is Yu, and the martial soul attribute is a rare thunder attribute. Could it be that this annoying little guy is a child of the Blue Lightning Tyrannosaurus Rex family?
This makes sense, this kid, why is he so arrogant..."

In an instant, Elena filled out a lot of information in her mind.And thought he guessed Tianlin's identity...

In comparison, there are indeed very few martial souls with the Thunder attribute...

Involuntarily, he changed his attitude a little bit.After all, the Blue Lightning Tyrannosaurus Rex family, as the strongest beast martial soul sect, is indeed so powerful that even the empire has to be afraid of it.

Naturally, she couldn't underestimate this one of the famous upper three sects.However, in the bottom of her heart, she still despises this dandy...

"You haven't said yet, what are you doing here?" Ya Li immediately questioned, unwilling to see this female knight chatting with Tianlin anymore...

"That's right. We all belong to the empire. Therefore, we want to form an alliance in the next exploration. Let's fight against forces outside the empire together!" Elena said bluntly, and glanced at the Spirit Hall team in front of her. .Even, I don't know how to cover up a little bit of a detour...

"The reason?"

"Wuhundian is stronger, we don't have the confidence to deal with it..."

'...' Tianlin was speechless.

This kind of thing, say it directly?Is it okay?Aren't you afraid of being heard directly by Wuhundian?

At this point, Tianlin basically understood the character of the blond female knight.

In short, she is a rigid knight who is deeply educated in chivalry, has a loyal personality, and puts the empire and family at the top. She is not good at flexible 'blank paper' knights.I haven't realized the sinisterness of society and the horror of people's hearts.

In addition, I don't know if she also abides by the chivalry spirit of justice...

"I reject!"

"Why? You shouldn't refuse!" Eileen's eyes widened. This was the first time someone rejected her proposal face to face.

"Why can't I refuse? If you want to fight, it's your business... I'm just here to experience adventure and seek excitement.

Is there any advantage in being allied with you? "Tianlin spread his hands, and also became a little interested, ready to tease this fierce female knight.

"This is for the empire, how can you ask for benefits?

If it was the precious things in the ruins, they would all be snatched away by the people of Wuhundian!Then what to do..."

"What does it have to do with me being robbed? Why should I care?"

"You, you...you are simply unreasonable! How can you be so selfish? You..." Elena was so angry that she wanted to stomp her feet.But he couldn't think of how to refute the boy's words.

……

After a while, Tian Lin made a slight detour: "Of course, it's not impossible for me to form an alliance with you. It's just that I also have one condition..."

"Tell me, let me listen first..."

"If any treasures are found in the ruins, I want to take away any one at will, you can't stop it! Can you?"

"No, the ruins in the empire belong to the empire! You have no right to steal..."

"Huh! Let's not talk about it. I want to give everything and get the support of others. I have never seen such a shameless person like you!" Tianlin complained angrily.

Immediately, the lady knight blew up on the spot, and couldn't help but angrily said:

"I, shameless? I..."

On the spot, he was ready to teach this arrogant boy a lesson.

Right here, a gentle and steady voice ended the comedy of disputes.

"Very good, old man, I promise you. As long as you and your people support the empire, then you can choose any one of the treasures unearthed from the ruins to take away. We will never stop it!"

"Professor!" Elena looked at Professor Ang Luo who was walking beside them, and asked repeatedly.It seems that it is very difficult to understand why Professor Ang Luo agreed.

"Little Linna! You still lack experience. You can't even tell a young boy..." Professor Ang Luo joked with a smile.

"I..." Thinking of his impulsive performance just now.The female knight was naturally a little ashamed, and most of the anger dissipated in her heart.

"How, little friend, is the alliance between us established?" Professor Ang Luo asked again.

"Okay. Established!" Tian Lin smiled and agreed.

Anyway, Tianlin's purpose is not those ancient relics in the ruins, so naturally he doesn't mind cooperating with anyone.

And, let's work together like this.Doesn't it look more interesting?
Therefore, Tianlin agreed to this alliance.

"Very good, I wish you a happy cooperation!" This Professor Ang Luo narrowed his eyes, his eyes were deep, as if he had misread Tianlin's disguise.

In this way, the fragile alliance between Tianlin and the empire was established...

……

And at this moment, the team was at the forefront.

The worker who was leading the way suddenly shouted: "We are here, we are here. We are right ahead!"

Then, as expected, a bright light shone from the end of the mine tunnel ahead...

Generally speaking, some large mines are too large due to too many mines.

All kinds of minerals mined in the depths of the mine are too time-consuming and labor-intensive to be transported out and then sorted and extracted.

Therefore, some larger cavities will be dug inside to serve as transfer centers.The excavated minerals will be sorted here for the first time.Then transport it out from the main mine to save manpower and material resources...

At this moment, the end of this main mine road is the first transfer center of the entire mine.

At this moment, this temporary team finally passed through the main mine.

Come to this so-called central mine.

For a while, everyone was shocked when they saw the mine for the first time.

Big!
Really big!
This central mine is as big as a football, and various sorting machines, mining machines, mining equipment, mine cars, etc... are parked here in a mess, at least hundreds of them.

Moreover, on the surrounding rock walls, not only are huge kerosene lamps lit, there are more than ten bright soul power lighting stones inlaid on the top of the cave, illuminating the entire mine quite brightly...

Looking at this magnificent big mine, for a while, everyone understood.

They were all deceived.

This is no small mine!
Nowadays, the largest mine in the entire empire is not necessarily bigger than the whole.

Moreover, on the surrounding rock walls, the dozens of hundreds of dark mine tunnel entrances are even more amazing.

It's hard to imagine how lively and vast this place is when it's not deserted!Who is it?Which ancient country was it?Such a magnificent mine was built here?

Is it just for mining?
Many doubts arise in the hearts of everyone, but no one knows the answer.

The answer needs to be explored by themselves...

……

At the same time, the ordinary miner who led the way quickly introduced: "My lords!
This is the 'hollow mine', from here, you can lead to any mine, and the minerals excavated from each mine will also be sent here for sorting..."

"Everyone! This is obviously one of the centers of the entire mine. I suggest that we spread out and search here.

See if you can find anything useful! "

As the oldest and most knowledgeable professor of history in the entire team.

Professor Ang Luo's proposal was also approved by everyone.

Immediately, under the orders of the leaders of each family, the Templars, mercenaries, imperial knights, etc., all dispersed.Began to explore the entire mine.

However, on Tianlin's side, the thirty guards also had green eyes and became greedy.

After all, although this is a mithril mine, the ore produced is not only mithril, but also many other rare ores.

If you can find some rare ores and sell them, you can also make a lot of profit.They were naturally ready to move.

Soon, after receiving the approval of Tianlin, the noble young master, these guards naturally dispersed and ran to search for rare ores.
However, compared with the orderly search operations of the Imperial Knights and Templar Knights, they are like a messy nest of mice...

Of course, Tianlin had no hope of these guards.

I just hope that they can play a good role in opening the way...

At this moment, the subordinates of several forces all ran to search.And all the leaders gathered together under the call of that Professor Ang Luo.

A follow-up action plan was discussed.

However, Tianlin finally had a good opportunity to take a look at the other 'leaders' of this mixed team...

……

After several people got together, Professor Ang Luo spoke first:

"Let me go first and introduce my findings.

According to the construction style here, and the construction of these minecarts.

It can be preliminarily judged that this mithril mine was built about 800 years ago.At that time, the two great empires, the Wuhun Palace, etc. had not yet been established.

The mainland is still in the chaotic Warring States period, and various small countries are fighting endlessly...

Based on the size of the mine, it can be inferred.Even in ancient times, mines of this level were extremely rare.Not a few years, nothing more than built.

And after hundreds of years, it still hasn't collapsed here.The surrounding stone walls even seem to be reinforced with steel bars, which has reached the level of a military bunker.It is hard to imagine that this will be a civilian mine! "

"Then, is this a mine or a relic?" On the side of the Spirit Hall, the saint Hu Liena also asked curiously.

"It's not yet possible to judge...

So far, I have not found any relevant records.There are no ancient characters carved on the stone walls here.Even if there are really relics, they must be in a deeper place! "Professor Ang Luo made a reasonable guess.

"Then, let's go! Go deeper. I'm more interested in the ruins." Xie Yue urged coldly, seeming quite anxious.

Hearing this, the bald leader of the mercenary group, Barrett, who had been silent all this time, suddenly spoke:

"I think it's necessary to find out more about what's going on here..." It reflected a cautiousness that didn't match that wild appearance.

Everyone agreed with this proposal.

As a result, several people began to ask the worker who led the way again.

"Tell me, what happened in this mine?
How did those first batch of miners disappear? The head of the Warhammer mercenary asked. Compared with the mysterious unknown ruins, he cared more about the truth about the disappearance of those miners.

In order to solve this strange thing quickly.

After all, their mercenary group just accepted the commission.Just to solve the problem and get paid from the Lord Viscount.

As for the Imperial Knights and the Hall of Spirits, he naturally couldn't afford to provoke them, and he didn't want to!

I just want to find out the truth of the disappearance as soon as possible, solve the problem, and leave here...

Facing the inquiries of these big shots, this ordinary farmer and miner was also very timid.

Hastily trembled: "This...

This is not very clear to me.All I know is that five days ago, we were digging hard in the mine.

Suddenly, the earth shook violently.Then, right there, the ground sank, and suddenly a big black hole appeared!
The cave was so deep that we threw candles down, but we couldn't reach the bottom...

Later, after the lord learned about it.I thought that there would be more treasures or ores under the deep hole, so I sent a miner, hanging a rope, to go down from there to investigate...

After a while, the miner climbed up holding a large piece of gold and a handful of mithril rough.Claims to be full of precious ore underneath.

Now, the lord's coke is broken.

Dang even dispatched more than a dozen miners, carrying large and small rucksacks, all sent down to dig, trying to dig out all the precious ores below.

It's a pity that after those ten people went down, they never came up again.Until today, there is no sound and no trace.

So much so that our other miners also panicked and panicked..."

"Earthquake? Dark pit? Gold? Disappearance?...These accidents seem a little weird when they come together." The bald leader Barrett couldn't help but wonder.and continued to question:

"Where is the deep hole you mentioned? Take us to see it!"

"Oh, oh! Just this way, this way."

Seeing this, everyone followed suit one after another, preparing to experience the deep hole of 'choosing someone and devouring'...

After a while, several people came to the southwest corner of the mine.

This piece, sure enough, a huge black hole with a diameter of about five meters has collapsed here.

The dark hole is bottomless, and all the light that shines in seems to be swallowed up, making it impossible for people to peek into what is underneath...

"Who knows how deep this black hole is?" Professor Ang Luo looked around and stopped at the miner leading the way.

"I, I don't know either! A few days ago, those workers were all tied down with a [-]-meter-long rope. I don't know how deep the hole is. But it should be within [-] meters!" The miner quickly explained with.

"..."

"Within a hundred meters? This is too vague. Everyone, who has a special martial soul, can you measure the depth of this black hole?"

Hearing this, everyone looked at each other, but no one spoke.

Unless it is a rare flying spirit, you can fly directly to explore.Otherwise, how could they know how deep the hole was.

It's just, it's a pity.Of those present, no one could fly...

For a moment, when everyone was silent.

A boy's voice broke the deadlock.

"I'll come!" Tianlin stepped forward and introduced himself.

"Son, can your martial soul fly?" Professor Ang Luo exclaimed in surprise.

Suddenly in my heart: "Blue Lightning Tyrannosaurus Rex Wuhun, can indeed fly!"However, this child is so young, even if the martial spirit can be controlled, he can't fly ten meters away, right?What is he trying to do? '

But Tianlin shook his head, and said calmly: "I don't need a martial soul..."

Then, under the suspicious eyes of everyone.He immediately picked up a small smooth stone next to him and threw it into the black hole.

Then he closed his eyes and counted down the seconds and listened.

After three seconds.

With a slight impact sound from inside the black hole, Tianlin suddenly opened his eyes and gave an answer:

"The hole is about 45 meters deep..."

"You, how are you sure?" Professor Ang Luo was surprised.

"You just threw a stone, and you know how deep the hole is? It's a lie!" A young businessman in the Soul Master Chamber of Commerce team immediately became suspicious, as if I didn't believe it.

"Professor, you can't believe this guy's words. He must be lying!" That Elena knight also immediately retorted.Obviously, he still has a prejudice against Tian Lin, a playboy...

Regarding this, Tian Lin didn't try to argue, and directly spread his hands: "Believe it or not."

Then, he returned to Sister Li and Xueyin's side.

After all, I have to explain to these guys what is called 'modern physics', what is called 'free fall formula', 'propagation of the speed of sound', etc... Knowledge cannot be explained clearly in a short time.

However, Tianlin can be sure that his calculation is not wrong.

Within a hundred meters, a small smooth stone can be regarded as a free fall, and it took about three seconds from when he threw the stone to hearing the echo.

According to the derivation of the formula h=(1/2)gt, and then deducting the sound speed back propagation time, it is natural to infer the approximate height of the black hole!

Well……

'Learn physics and chemistry well, travel all over the world'

Fortunately, I remember a little physics knowledge from my previous life...

……

This Professor Ang Luo chose to believe in the doubts surrounding others.

Although he didn't know how the mysterious boy knew.However, he did not see the slightest timidity and lies in the other party's eyes.

Obviously, his intuition told him.This young man did not lie...
