One Piece:Becoming the King of the World from the Rocks Era

The Nue, surrounded by a black-and-white aura of cursing power, transformed Akame immediately upon consuming the Devil Fruit. Without hesitation, Li Yuan placed Seastone cuffs on her, making Akame the third child to collapse on the ground.

"Akame, the curse power is very strong and dangerous. Until you can control it, you must keep the Seastone cuffs on," Li Yuan instructed seriously. The curse power was dangerously close to rule-based abilities.

"I understand, Daddy!" Akame replied weakly.

"Daddy, I want to choose the Logia-type Rumble-Rumble Fruit," Faraday announced after seeing his brother Weizhuang hesitate.

"Are you sure, Faraday?" Li Yuan asked earnestly.

"Yes, Daddy, I'm sure. It's the strongest Logia-type Rumble-Rumble Fruit. How can I not choose it?" Faraday replied confidently.

"Alright, this Devil Fruit is yours," Li Yuan said, handing the Rumble-Rumble Fruit to Faraday.

"Ugh!!!" Faraday barely took a bite before his stomach churned, almost making him vomit.

"Faraday, you must finish the Devil Fruit; otherwise, it might hinder your power development!" x3

Esdeath and the others chimed in unison from their prone positions, displaying unusual harmony amidst their discomfort.

"I'll eat it!" Faraday glared at his siblings lying like salted fish before devouring the fruit.

"Crackle!!!" After finishing, Faraday's lower body transformed into lightning, causing him to float.

"Bang!!!" However, before he could fully experience the Rumble-Rumble Fruit's power, he was drained of energy and collapsed beside Akame and the others.

"Weizhuang, don't you want a Devil Fruit?" Li Yuan asked, curious about the last child's hesitation.

Among the remaining fruits, aside from those already chosen by Akame and the others, were the Human-Human Fruit, Mythical Type: Great Monk Form, the Paramecia-type Door-Door Fruit, and the Paramecia-type Comet Fruit, all of which Li Yuan considered powerful.

"Dad, I don't think any of these Devil Fruits suit me. I'll wait until I find one that's right for me," Weizhuang replied seriously.

As his father said, a Devil Fruit is a lifelong ability, and it shouldn't be chosen lightly. It must be the right fit.

"Alright, if you don't find anything suitable now, we'll wait. When I find more powerful Devil Fruits, I'll show them to you," Li Yuan nodded. If Weizhuang wasn't interested in the current options, he wouldn't force him. Eating a Devil Fruit later wouldn't be an issue.

"Esdeath, you little ones, now that you've eaten Devil Fruits, you must focus on developing and training them."

"I'll set specific training tasks for you. You must complete them daily, understood?" Li Yuan said sternly to his children.

At eight years old, they were ready for foundational training. As his children, they were destined to be extraordinary. Li Yuan would guide them to become strong.

In this harsh world, without power, one had no rights!

"Yes, Daddy!" x5

Esdeath and her siblings realized their carefree childhood was over. Ahead lay rigorous study and training.

Li Yuan would schedule physical and Devil Fruit training for his children, along with lessons in basic etiquette, war knowledge, and various philosophies. He wanted them to be well-rounded, not just powerful fighters.

If there was a template for his children's development, it would be Sengoku, who was both wise and brave!

Li Yuan nodded and left with Shakky and the others.

"Li Yuan, aren't Faraday and the others too young?" Yadina expressed concern, recalling the training plans Li Yuan had previously outlined.

After all, they were just children, only seven or eight years old. At this age, other kids were enjoying their childhood and parental love, not facing such intense training and studies. It seemed too harsh for their children.

"Yadina, our children are destined for greatness. They can't live like ordinary children."

"The Infinity Pirates will be theirs to lead. If they're too weak, they can't bear the burden of the Infinity Pirates," Li Yuan reassured Yadina, understanding her concerns as a father.

He wished for a better life for his children, but the world didn't belong to him, so they had to adapt.

"Don't worry, sister. Akame and the others are naturally stronger. They'll grow quickly," Shakky comforted Yadina.

As Li Yuan's children, transformed by the Sword God Tempering Technique and vampire lineage, they possessed great innate talent, surpassing even Li Yuan before setting sail.

With this foundation and the Devil Fruits, as long as they weren't lazy or reckless, becoming strong was inevitable.

"Li Yuan, I've distributed the Infinity Swordsmanship and Navy's Six Styles manuals across the New World as you instructed," Shakky reported.

"Next, spread them to the first half of the Grand Line and the Four Seas," Li Yuan instructed.

"Li Yuan, I understand spreading the Navy's Six Styles, but why share our Infinity Swordsmanship?" Lazuli asked curiously.

Even though the distributed Infinity Swordsmanship was a simplified version for swordsmen below the rank of swordsman, it was still revised by Li Yuan himself and not inferior to any swordsmanship in the world.

Such valuable knowledge, shared freely, puzzled her. Shouldn't they keep it for themselves?

"Is it because you want to increase the world's overall strength, causing turmoil with new strong individuals?" Yadina speculated after some thought.

Possessing the Insight Fruit, she quickly grasped the core issue.

"Hahaha, exactly as Yadina thought," Li Yuan confirmed.

"This world is filled with darkness and oppression, where the weak are powerless."

"But when they gain strength, they'll resist, and some will seek revenge against their oppressors."

"Most of these people are commoners or slaves without power. Once they act, the Navy and World Government will hunt them."

"They'll have to turn to piracy, increasing pirate numbers and indirectly strengthening them, weakening the Navy and World Government," Li Yuan explained.

The Infinity Swordsmanship was accessible to anyone willing to train, while the Navy's Six Styles, a physical art surpassing ordinary humans, offered gifted individuals a chance to grow.

While perhaps only one in 10,000 might master these techniques, that still meant a substantial number of people worldwide.

In seven or eight years, the world's power level could rise significantly due to these training methods.

With newfound strength, many wouldn't accept being oppressed and would resist.

Faced with insurmountable forces, they'd have the confidence to take to the seas.

Li Yuan never hid his ambitions from his women, who fully supported him, understanding the scope of his dreams.

"Don't worry, Li Yuan. I'll ensure the Infinity Swordsmanship and Navy's Six Styles reach the entire world," Shakky assured.

Holy Land Mariejois:

"The Donquixote family has removed their Celestial Dragon chips, severing ties with us!"

Legal God of War Vauchery Saint announced gravely.

The other Five Elders wore grim expressions. This was a disgrace for the Celestial Dragons!

Even those raised in their homes weren't so foolish as to abandon their Celestial Dragon status!

"Since they've forsaken it, let them go!"

"But this must never be publicized. When they're dead, we'll erase their islands!"

Financial God of War Nassourang Saint declared.

Though the Donquixote family was no longer Celestial Dragons, they wouldn't dirty their hands. Once the lowly people killed them, they'd eradicate those people, wiping away this shameful history.

"Agreed!"

"Agreed!"

"Agreed!"

"."

"Captain, Captain, I've succeeded!" Scientist Yumaz exclaimed, rushing to Li Yuan with a sword.

"Which experiment succeeded?" Li Yuan asked, puzzled.

"Captain, I successfully fused the Great Grade Sword Ame no Habakiri!" Yumaz excitedly handed the sword to Li Yuan.

"Clang!!!"

Li Yuan took Ame no Habakiri, feeling its new form.

Using the Fusion Fruit's power, Yumaz had reforged Ame no Habakiri with a mineral capable of creating a Great Grade Sword.

"The blade is half a foot longer, an inch wider, five kilograms heavier, sharper, and more durable."

"Excellent, Ame no Habakiri's overall power increased by fifty percent," Li Yuan said, satisfied.

The sword, famed for cutting through the sky, was now even more formidable!

"Yumaz, you've done well. From now on, for any of your projects, coordinate with Yadina for funding. As long as they're not too demanding, she'll approve them," Li Yuan praised.

Yumaz's Devil Fruit development had finally made a breakthrough, and he could now enhance Great Grade Swords. Supreme Grade Swords seemed only a few years away.

"Thank you, Captain!" Yumaz beamed, inspired by Li Yuan's support for his scientific pursuits.

"Don't celebrate too soon. Next, you need to enhance Asura Doji's Earth Destruction Sword."

"After that, I have three more Great Grade Swords: Yama, Nidai Kitetsu, and Black Blade Shusui, needing enhancement," Li Yuan added.

Rather than forging new Great Grade Swords, Li Yuan preferred enhancing existing ones, making them stronger.

In the pirate world, quality always trumped quantity.

"Understood, Captain!"

Despite the daunting task of enhancing four Supreme Grade Swords, Yumaz agreed, his face pale.

It had taken a month to complete Ame no Habakiri's enhancement, working to exhaustion before resting and resuming.

He decided to finish Asura Doji's sword first, then take his time with the rest, knowing Li Yuan didn't urgently need them.

"Yumaz, have you tried fusing anything besides minerals?" Li Yuan inquired.

"I've tried, but many failed. For example, fusing watermelon with minerals failed, but different minerals succeeded. Watermelon and apple fusion worked."

"Also, biological and non-biological fusions, like chicken with minerals or fruit, failed. But biological fusions, like chicken and pig or human and cow, sometimes succeeded."

"The failures were due to conflicts between their souls, causing mental confusion," Yumaz explained.

"So, I concluded that similar non-biological fusions succeed, non-biological and biological fusions fail, and biological fusions have a chance," Yumaz said.

"Yumaz, the failures may not only be due to biological and non-biological conflicts but also the limits of your fruit's development."

"Continue developing your abilities. The Fusion Fruit's potential is more than what you've achieved," Li Yuan advised, encouraging Yumaz.

Paramecia Devil Fruits are powerful, theoretically offering limitless possibilities, but realization depends on individual talent.

Li Yuan had guided Yumaz on the fruit's development and theories, but Yumaz struggled, reflecting individual capability.

Not everyone could wield their fruit like Doflamingo, creating intricate techniques and achieving awakening.

Monsters like Law, Kid, Doflamingo, and Luffy in the original story all reached awakening, but Yumaz's potential as a monster remained to be seen.

Since Li Yuan's conversation with John, the Infinity Pirates' Thomas Shipyard received numerous orders.

With a steady resource supply, shipwrights worked overtime, producing thirty ships in months.

These were wooden ships, half of which were modified old ships with new propulsion systems.

These ships, ordered by New World's great pirates from Li Yuan, allowed them to traverse the Calm Belt, proving their capability.

This success made Thomas Shipyard world-renowned, with more orders flooding in, especially from the Four Seas!

"The Calm Belt's natural barrier has been shattered by Thomas Shipyard!"

"Ships capable of New World voyages have been born at Thomas Shipyard!"

"The era of sailing the Calm Belt has arrived!"
