In the Demon Suppression Division, the Iron-Cutting Sword Technique is perfected

In the overcast sky.

Gu Cheng flew with his Qi, his speed was amazing, like a blood-colored stream of light cutting through the sky.

Although the Willow God was a little weak, it was a great demon of the high level of the Innate Realm after all, and its remains after death contained a vast vitality.

Gu Cheng devoured it completely with the Blood Furnace, which was a bit "indigestible".

He must find a secluded place as soon as possible to completely refine this power.

While thinking, Gu Cheng had already landed on a mountaintop where few people went.

He scanned the surroundings with his divine sense, and after confirming that it was safe, he sat cross-legged on a piece of bluestone and slowly opened the system panel.

"Let's get started..."

Gu Cheng took a deep breath, and the vast life span poured into his body, driving the refining process of the Blood Furnace.

And his whole body was filled with a terrifying aura that made people's heart palpitate...

[Year 1: You try to transform the life force of the Willow God's body into the blood evil force needed to practice the "Blood Sword Sutra".

Because your "Blood Furnace" and this innate evil skill have the same origin, there is no sense of sluggishness in the conversion, and it can perfectly replace the evil blood required for practice, and the effect is even better.

However, the origin of demons is very different from that of humans, and the energy they devour is extremely complex. If you want to completely refine it, you will inevitably consume a lot of life. 】

"It works!"

Gu Cheng's eyes flashed with a gleam of light, and his previous speculation was indeed correct.

As for the large amount of life required for this refining... can this be called a problem?

The thousand-year-old tree demon and the leader of the Blood Sword Sect he just killed have contributed more than 1,800 years of life in total,

equivalent to thirty-six Tang Yuan!

It is easy to purify all the complex energy and turn the original soup into the original food.

…

[Six hundred and eighty-third year: You will completely refine the energy you have swallowed and transform it into an extremely pure blood evil force. Driven by this force, your Blood Sword Sutra will improve rapidly. ]

[Seven hundred and eighth year: After years of hard training, you will absorb the refined blood evil force and completely integrate it into your body. The Blood Sword Sutra breaks through the realm of ‘mastery’! ]

[Physical training: Innate fifth level]

[Remaining lifespan: 3,259 years]

“…”

Gu Cheng slowly opened his eyes, and a gleam of light seemed to flash in the depths of his eyes.

He stood up, stretched his muscles, felt the mighty power surging in his body, and couldn’t help but raise a satisfied arc at the corner of his mouth.

Innate realm, one step at a time.

Every breakthrough in a small realm is like sailing against the current, with many difficulties, but the improvement in strength it brings is also earth-shaking.

When he fought with Duan Feng before, the opponent was taking drugs and transforming, which really made him spend a lot of effort.

It took more than 30 punches to break the blood demon transformation of Lao Deng.

But with Gu Cheng's current strength, even if he didn't activate the mystery of "Immortal Demon Body".

The leader of the Blood Knife Sect would definitely not last ten rounds in his hands!

"In this way, as long as I hunt a few more demons in the innate realm, I can complete the third volume of "Blood Knife Sutra" all the way to perfection!"

Gu Cheng thought to himself and decided to strike while the iron is hot while he is in good shape.

He took out the demon core of the Willow God from the storage bag, swallowed it in one gulp, and refined it at the same time.

The demon core of the thousand-year-old tree demon is the ultimate manifestation of the thousand-year cultivation of the Willow God.

The difficulty of refining it is far beyond the ordinary innate realm demon.

But under the ruthless pressure of Gu Cheng's vast lifespan, this demon core could only surrender obediently, turning into extremely pure energy and merging into his body.

…

[Chapter 563: You finally completely refined and analyzed the demon core obtained from the Willow God.

The majestic vitality contained in it nourishes your body like spring rain, and your lifespan has increased by a hundred years.

Not only that, the healing secrets contained in the Willow God's demon core have given you a completely new understanding of the relevant spells and martial arts.

After years of meditation, you suddenly realized that you learned a new magical power from this demon core. ]

[You have comprehended the magical power - Xiantian·Rejuvenation]

[Xiantian·Rejuvenation: The grass and trees are in spring, and the dead trees are blooming. Your body contains the powerful vitality of the grass and trees, and your recovery ability is far beyond that of ordinary people.

Even if you are seriously injured, you can burn your own lifespan and return to your peak state in an instant! 】

"Oh? Isn't this the Willow God's innate magical power?"

Gu Cheng's eyes lit up. He had experienced the Willow God's strong self-healing ability in the previous battle.

If he didn't have the "damage" magical power, he wouldn't have won that battle so easily.

Now that the "rejuvenation" magical power has fallen into his hands, coupled with his life span of thousands of years, it is simply infinitely expanded.Cheng Yaojin of the Phoenix.

Unless he can be killed in an instant, or has a healing ability similar to the "damage" magic.

Otherwise, even if he stands still and lets others hit him, it will be difficult for him to die!

Thinking of this, Gu Cheng's heart was slightly relieved, and then he continued to krypton life, and invested all the remaining lifespan into the deduction of "Yin Yang Absolute Immortal Hand".

With the help of the Willow God Demon Core, this deduction process went smoothly.

In just over four hundred years, this perfect innate martial arts has once again broken through to a higher level!

…

[The 441st year: The two energies of Yin and Yang flow, the power of life and death interweave, your "Yin Yang Absolute Immortal Hand" breaks through the limit and comprehends the ultimate meaning of martial arts.

According to the characteristics of this mystery, you named it: Yama Finger! ]

[Yanwang Finger: Burning Yang life, life and death in an instant, by burning your own life, greatly enhance the power of "Yin Hand" and "Yang Hand", and gather on one finger.

Like the judge of the underworld, one finger saves life, one finger kills people! 】

[Remaining lifespan: 2,355 years]

"Why is it another life-saving move...

No wonder this tree demon can extend its lifespan by absorbing the demon core for a hundred years. It turns out that it is waiting here."

Gu Cheng chuckled and shook his head.

Lifespan is just an inexhaustible resource for him. This kind of martial arts that fights for life seems to be tailor-made for him.

After breaking through the "Yin Yang Absolute Immortal Hand" to the ultimate artistic conception.

Gu Cheng closed the system panel with satisfaction, took out Duan Feng's storage bag, and began to count the spoils.

As the new leader of the Blood Knife Sect.

Duan Feng's belongings are quite shabby, and there is no comparison with the collection of the foodie elder.

Gu Cheng rummaged in the storage bag for a long time and found two valuable treasures.

One of them was a fist-sized blood-colored bead. As soon as he got it, he felt a chilling aura coming towards him.

As expected, this should be the goal of his trip, the Blood Sword Sect's treasure - the Blood Soul Bead!

Gu Cheng held the Blood Soul Bead in his palm, but found that it was covered with fine cracks, and the spiritual energy that was originally full of it had been lost. It was obviously close to being scrapped.

"Is this magic weapon broken?"

"It's a pity that I didn't explode its soul afterimage after killing the Willow God, otherwise I could find a way to repair this Blood Soul Bead."

Gu Cheng frowned, feeling a little disappointed.

You know, without the help of this Blood Soul Bead, his "Heavenly Demon Blood Transformation Method" obtained from the foodie elder would have no way to practice it!

But on second thought, the two Blood Soul Beads of the Blood Sword Sect were obtained by Lin Xueyi from a rebirth sect stronghold two hundred years ago.

Now the Rebirth Sect has revived, and he happens to know a secret inheritance realm of the Rebirth Sect.

It shouldn't be difficult to get another Blood Soul Orb.

"Besides, my current body cultivation has just reached the fifth level of the innate realm, and the evil art of the Spiritual Sea Realm is only a fragment, so there is no need to rush..."

Thinking of this, Gu Cheng sighed.

He put the broken Blood Soul Orb into the storage bag and turned to check the second treasure.

This is a palm-sized blood-colored token, which is cold to the touch, and no one knows what material it is made of.

On the front of the token, there is a ferocious and terrifying three-headed and six-armed evil ghost engraved, with a lifelike face, as if it is about to choose someone to devour.

On the back are several characters that he doesn't recognize at all, with sharp strokes and a chilling murderous aura.

"What is this again?"

Gu Cheng looked puzzled and tried to probe his mind into it.

The next moment, a strange picture appeared in his mind... This mysterious blood-colored token was actually a map!
