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

"Marie, is it? I've got my eyes on you. Now, show me your strongest attacks. Let me see how powerful you are," Li Yuan nodded and said.

"Yes, Boss!"

With Li Yuan's command, they surrounded him, drew their weapons, and began attacking.

"Bang! Bang! Bang!"

These pirates were much stronger than Kano's group, capable of causing significant harm to Li Yuan. At least Marie's sword could slash two centimeters deep into his flesh, which was quite an achievement.

However, Marie was bewildered. His full-strength blow only left such a minor wound on the boss?

He clearly saw that his boss was taking the full-force attack with just his physical body, without using haki or the Navy's iron body technique.

"Haven't you eaten? Attack me with all your might!" Li Yuan suddenly shouted.

"Yes!!!"

With Li Yuan's roar, the pirates dared not hold back any longer and attacked with all their strength.

They continued their assault for an hour before finally stopping. The pirates were exhausted, but Li Yuan felt no fatigue; instead, he felt invigorated, sensing that his physique had grown slightly stronger.

"That's enough for today. You can do whatever you want now. If you want me to instruct you in swordsmanship or other areas, come find me when the sun sets," Li Yuan said after cleaning himself up.

"Yes, Boss!" Marie and the others responded excitedly at the prospect of receiving guidance from Li Yuan.

They sought Li Yuan not only for protection but also for his instruction to enhance their skills.

In this world, personal strength is the most reliable guarantee.

Feeling the increased goodwill from his subordinates, Li Yuan nodded in satisfaction.

Since they were his first batch of subordinates, giving them some benefits was no problem. This way, more people would genuinely want to follow him in the future.

After finishing his morning exercise, Li Yuan donned his weighted iron armor and jumped into the sea, submerging into the nearby seabed, sword in hand, to practice.

Having received numerous swordsmanship notes from Shakky yesterday, Li Yuan spent the night reading and memorizing them.

But memorizing is one thing; understanding and integrating them into his own swordsmanship is another.

As he entered the sea, he recalled the training method of the Swift Wind Swordsmanship.

Swift Wind Swordsmanship was a style created by a powerful swordsman, acquired by the Rocks Pirate Group, and now being learned by Li Yuan.

"Swing the sword as fast as the wind!"

Recalling the content of the Swift Wind Swordsmanship, Li Yuan began practicing it in the sea.

The essence of Swift Wind Swordsmanship is speed: drawing the sword at lightning speed, swinging it faster than the eye can follow, and delivering slashes invisible to the naked eye. Speed permeates the entire sword style and is its essence.

Even in the deep ocean, with immense water pressure and resistance, Li Yuan's speed was astonishingly fast, seemingly unaffected by the sea.

His casual slashes reached hundreds of meters and stopped only after traveling nearly five hundred meters.

To transform other sword styles into nourishment for his own swordsmanship, he must first grasp their essence, learn them, and then deconstruct them.

By integrating what he learned and observed during deconstruction into his own style, he could strengthen his swordsmanship.

Currently, Li Yuan was in the process of learning other sword styles.

As Li Yuan trained in the sea, the once-calm waters turned turbulent.

Occasionally, massive slashes would fly out, and anyone venturing near that part of the sea might find themselves buried there.

"Boss's training is so exaggerated," Marie said in shock, watching the gigantic waves in the ocean.

"This is nothing. When Senior Brother trained, it was even more dramatic. You'll see this often in the future," Kano said as he walked over. He knew these were Li Yuan's subordinates, now part of the same crew, so he came to introduce himself.

"And you are?" Marie asked, looking at Kano.

"My name is Kano. I trained at the same dojo as Senior Brother, your boss. We later set sail together and joined the Rocks Pirate Group," Kano explained without hiding anything.

"So, it's Brother Kano. We're brothers on the same ship now. I'm Marie," Marie said respectfully upon realizing Kano was his boss's junior brother, acknowledging their relationship.

"That's right, we're brothers now," Kano replied, accepting Marie's goodwill.

"Swift Wind Swordsmanship has something to offer. This method can enhance my sword-drawing speed and fits well into my Infinite Swordsmanship," Li Yuan thought.

After practicing Swift Wind Swordsmanship all morning, he quickly mastered it.

At his current level, learning another swordsman-level style was straightforward.

Next, he would integrate the essence of Swift Wind Swordsmanship into his own style, elevating it further.

In the afternoon, Li Yuan found a massive rock weighing about two thousand tons.

"Lift it!"

With great effort, Li Yuan raised the huge rock with both hands.

"Moonwalk!"

In the next instant, he kicked off the ground, leaping into the air with the rock, and used Moonwalk to run in the sky.

This was his method to simultaneously train his stamina, endurance, arm strength, leg strength, and aerial combat abilities.

As Li Yuan sprinted off into the distance with the rock, Marie and the others could only see the enormous rock flying through the air, unable to spot Li Yuan, indicating just how massive the rock was.

"Boss's training is so rigorous," Marie remarked, watching Li Yuan's relentless training session.

"Since the boss is training so hard, we can't fall too far behind. We must train diligently and catch up to the boss!" Marie said.
