--- Chapter 304 ---

East Blue, Shimotsuki Village. 

Clank! 

A heavy hammer hitting a metal in a dimly lit room. 

The crisp sound reverberated. Two shadows were 'faintly' cast by the flicker of a vibrant orange flame in the burning forge.

"Come on, Old Man. You can do better than this!" Shouted a blue-haired young man, who wore nothing but his tattered brown pants. 

"Shut up. You have no comment on my creation, brat!" Replied an elderly with a large, thick unibrow that jutted to the sides of his face. The elder is sweating like no tomorrow, having a blacksmith hammer in his hand. 

He furiously hammered the hot iron due to the young man's comment, shaping it into the finest sword known to man. 

Crack!

Unfortunately, as the elder hit the hot iron, it cracked under the pressure and turned into a worthless product. 

"Gosh, Damn it!" The elder slammed his hammer down angrily. 

"Brat, you jinx it!" 

The blue-haired young man is none other than Huo Yuhao. 

After witnessing the lost history of Tiny World, Huo Yuhao got sent to the supposed 'right' timeline. Yet here he was, teleported to a timeline roughly a decade away before the story started.

Huo Yuhao was annoyed but could do nothing about it. 

According to Evo, the space and time continuum fabrics in the Tiny World are messed up because of the Ostera Race's sealing technique. The seal couldn't trap Huo Yuhao's movement in the Tiny World, but it would be mildly inconvenient for him to walk around.

Not to mention, Huo Yuhao is also fetching the girls on the way to the 'correct' timeline.

Yes, the girls also get sent to the wrong timelines. 

The side effects of his overwhelming luck are showing much faster than Huo Yuhao thought.

Huo Yuhao glanced at the unibrow elder, "Old Man, I have been here for a few days, but you have to prove to me that you can make decent swords." 

"Hmph, you're all talk." 

"Tsk." The unibrowed elder clicked his tongue in dissatisfaction.

The Old Man Huo Yuhao called is Shimotsuki Kozaburo. 

Shimotsuki Kozaburo is a famous swordsmith from the Land of Wano, and he secretly gets out of his homeland and roams around the world before settling in this small village. 

He has a son and a granddaughter connected to one of One Piece's main casts, Roronoa Zoro. 

He's the maker of Wado Ichimonji.

One of 21 Great Grade Blades wielded by Zoro until this very moment, well future, to be exact. 

Honestly, Huo Yuhao met Kozaburo by accident.

Three days ago. 

Kozaburo is fishing on the coasts near the Shimotsuki Village. He's reeling in quite a catch when a blue flash crashed on the sea and snapped his fishing line.

"Who the fuck?!" Kozaburo couldn't believe his eyes. 

A blue-haired young man appeared out of nowhere. He was clad in a white coat, making him look dashing, especially with that otherworldly handsome face.

"Where am I?" Huo Yuhao looked around in confusion. 

'Damn. I won't let this brat get close to my granddaughter.' Kozaburo believed Huo Yuhao's appearance was a test to make his old heart restless.

Huo Yuhao and Kozaburo stared at each other. 

As they were both blacksmiths, they could tell each other aura. 

Huo Yuhao was amused.

Meanwhile, Kozaburo was shocked because he felt oppressed by another swordsmith for the first time. Not to mention, Huo Yuhao looks young!

It was a comical encounter, for sure. 

Close is not the right word to describe Huo Yuhao and Kozaburo's affinity, but they can understand each other. 

With that, the burning rivalry in Kozaburo's old heart sparked, and he has been challenging Huo Yuhao ever since.

"Another failure, huh?" Said someone who entered the small workshop.

"Father, you should stop challenging Young Master Huo." 

"Your health is declining as time passes." 

It was a man with black hair tied back in a long ponytail and wore glasses with circular frames. He wears a gray yukata with two crossed swords on the left breast.

He's Kozaburo's son, Shimotsuki Koushirou. 

"Shut it! I won't die before I make a Supreme Grade Blade and win against this brat!" Kozaburo roared at his lanky son. 

Koushiro gazed at Huo Yuhao helplessly, and the latter only smiled as he didn't mind Kozaburo's words. 

Huo Yuhao glanced behind Koushiro and spotted a young girl peeking from his gray yukata. 

The young girl had short, dark blue hair and large, dark eyes. She wore a light pink short-sleeved shirt with a three-buttoned placket that she left unbuttoned, dark maroon shorts, and brown shoes.

She's Kozaburo's granddaughter, Kuina. 

In the canon, Kuina died at 11 from falling off the staircase. 

Huo Yuhao always thought it was such a bullshit way to die. 

But he wouldn't judge the logic because many people die in a similar case in the slippery bathroom. 

Kuina shyly stared at Huo Yuhao and greeted, "M-Morning." 

Huo Yuhao smiled at her, "Morning, Kuina-chan." 

"Mm." Kuina hid behind Koushiro again. 

Kuzaburo's mouth twitched, "GET AWAY FROM MY GRANDDAUGHTER, YOU BRAT!" 

"Okay, okay, chill." Huo Yuhao went to the coat hanger to grab his white coat and left the small workshop. 

Koushiro shook his head wryly, "You should treat your rival better, Father." 

"You said it yourself. Young Master Huo was a better swordsmith than yourself." 

"Hmph, I don't mean it." Kozaburo snorted. 

"Kuina, remember. Don't get closer to that brat. He's a bad guy." He added while looking at his dear and adorable granddaughter.

"Why?" Kuina only tilted her head in confusion, though. She only thought of Huo Yuhao as a handsome big brother she had a crush on. 

It was 'normal' for a kid her age to have a crush, especially when Huo Yuhao was indeed too handsome. Yes, even the older sisters and aunties in the Shimotsuki Village, like Huo Yuhao. 

"Just don't get closer to him, okay..." Kozaburo said solemnly.

"Hmm, okay." Even though Kuina replied to Kozaburo like that, she didn't mean it.

They are related. 

Unknown to the Shimotsukis, Huo Yuhao could listen to their conversation miles away. 

"That damned Old Man. Does he think I'm a Lolicon?" Huo Yuhao cursed while kicking a rock on the side of the road. "I'm only interested in legal women, and 99% of them are Milf!"

An Infinite Dragon God is sneezing back at the Douluo Dalu World.

Huo Yuhao sighed and stared at the distance. 

After staying in the Shimotsuki Village for a few days, he still couldn't find a clue where the girl he brought into this world was. He used Divine Sense many times, but the result was null. 

He even ordered Evo to do deep scanning on the Tiny World, but the result was an error due to the faulty space and time. 

He could only search for them manually. 

However, One Piece is a big world, which is ironic because it was a Tiny World.

Huo Yuhao rubbed his chin, "What should I do..."

"I don't want to do things too extreme, or else I would cause divergence in the timeline, causing a butterfly effect for my past self."

"Should I become a pirate, too? That doesn't guarantee me finding them."

"There is no other choice..." 

Huo Yuhao closed his eyes and activated the Ancestral Eyes of Heavenly Dao. He used the Heavenly Dao of Destiny to see the invisible lines of fate, using them to find people connected to him. 

Some lines traced back to the Shimotsukis in the small workshop, which Huo Yuhao didn't find surprising.

"As expected..." Huo Yuhao's eyelids twitched slightly as the lines in the air were too messy. "This world is on the verge of splitting apart." 

He focused on the far ocean and stopped after hundreds of miles as a blue-haired young lady in a tight battle suit entered his vision. She is blasting the sea with her golden spear.

"Found you." 

Huo Yuhao was about to teleport there when a green-haired kid jumped out of bushes and aimed a Shinai(bamboo sword) at him. 

"Hey, you! I challenge you to a duel!" The green-haired kid shouted.

Huo Yuhao dumbly stared at the kid and thought, 'I have been hiding from you for the last few days. Why did you randomly appear here like those hidden trainers in Pokemon?' 

'Damn it, Zoro. Your sense of direction works as worse as the Anime depicted!' 

Yes, this green-haired kid is the young Roronoa Zoro.
