The cultivation base is returned ten thousand times, and the starting strength is at the Four Empero

In the tranquility of Shimotsuki Village.

The swordplay duel between Kuina and Koshiro is in full swing.

The father and daughter stood in a wide open space, the air filled with an oppressive feeling of sword energy.

Koshiro, as a great swordsman, swung his heavy blade, and each sword seemed to carry the weight of a mountain, with great force and power.

However, Kuina was as steady as a rock, her sword moves were varied, and the sword light was like a meteor streaking through the night sky, continuous and uninterrupted.

"Come on, Kuina!"

"Use your full strength to show me!"

Koshiro shouted loudly and swung his sword towards Kuina, and the sword energy surged like a mountain torrent.

A cold light flashed in Kuina's eyes, and she drew her sword without hesitation to fight back.

The armed color domineering aura surged, and the sword body trembled slightly.

As her power surged, a heavy sword energy collided with Koshiro's sword, making a deafening noise. The air was instantly distorted, and the powerful shock wave blew the surrounding trees to and fro.

Koshiro sneered and used more force, as if he wanted to chop Kuina in half with his sword.

However, Kuina did not back down, her eyes became even more determined.

Then, the observation Haki that could briefly foresee the future erupted in her body.

It was as if he could sense every subtle change in Koshiro's sword moves.

Her figure flashed by, and the sword light streaked across the sky like a meteor, accurately hitting Koshiro's sword.

"KENG——" a crisp sound.

Koshiro's long sword was knocked away by Kuina's sword.

Sparks flew from the collision of the sharp sword blade and iron, and the long sword was knocked to the ground, raising dust.

Kuina did not stop. She quickly put away her sword and stood in the air with a firm look, unwavering.

Koshiro was stunned for a moment, and the expression on his face gradually became surprised, until he finally reacted and showed a relieved smile.

"Well, you are worthy of being my daughter!"

Koshiro laughed loudly. Although he was defeated in swordsmanship, his heart was filled with pride and honor.

I can see my daughter surpassing me in kendo.

Having even reached such a state, he felt extremely satisfied.

Kuina smiled slightly and sheathed her sword, her eyes sparkling.

"Father, you are too kind."

"If you were in the One Punch World, I believe your swordsmanship would improve rapidly!"

……

Zoro, who was standing next to them, stared blankly at the competition between father and daughter, with a look of deep shock in his eyes.

He never thought that Kuina could be so strong.

"She is so amazing."

Zoro muttered to himself, his heart filled with admiration.

Kuina's swordsmanship has surpassed his original understanding.

And his own swordsmanship seems to have a long way to go.

"I have to work harder! I can't fall behind her anymore!"

Just then, Ning Chuan came over.

He watched the entire confrontation between father and daughter.

Ningchuan discovered that Kuina's swordsmanship had improved a lot during this period.

It seems that Kuina has gained a lot from the training in the Kendo Association!

"Good job, Kuina."

Ning Chuan walked forward and praised softly, with a hint of approval in his eyes.

"You have reached a very high level of swordsmanship."

"According to the level classification of this world, your swordsmanship has reached the level of a great swordsman!"

Kuina looked at Ningchuan and narrowed her bright eyes slightly.

She was very happy to be praised by Ningchuan!

After praising Kuina, Ningchuan turned and looked at Zoro beside him.

"Zoro, do you want to become as strong as Kuina?"

Hearing this, Zoro was stunned for a moment.

There was a hint of desire in his eyes.

He gritted his teeth and spoke firmly.

"Of course!"

"I want to be the strongest swordsman in the world!"

Ning Chuan smiled and nodded.

"Ambitious!"

"Very good, since you have such ambition, then follow me!"

After he finished speaking, he waved his hand and opened a space door.

Zoro was stunned, then turned to look at the village behind him.

He then looked at his master Koshiro who was standing beside him.

When he saw Koshiro nodding to him.

Zoro took a deep breath and walked into the space door opened by Ningchuan without hesitation.

Ningchuan brought Zoro directly to Windmill Village.

And introduced Zoro to Luffy and the other three brothers.

Tell them that this guy with green hair will also follow them to the new world to gain experience.

Soon, these four guys of similar age started fighting together.

For a moment, the field was filled with domineering power!

Ning Chuan didn't care about the scene where these guys started fighting as soon as they met.

After all, he had other things to do.

Immediately afterwards, Ning Chuan opened the door of space again.

Went straight to the Ballati Restaurant on the Sea and found Sanji.

Over the past few years, Sanji's cooking and fighting skills have improved a lot.

But since they didn't go out to sea, they could only look for opportunities to practice with the Seraph warriors stationed on the ship.

There is a big gap between his strength and Luffy and the others.

But after all, Sanji is also one of the protagonists and can influence his integration into the pirate world.

Ningchuan was also planning to bring this guy to Luffy and the others.

Let them go to the One Punch World together.

After saying hello to Ningchuan and Zeff, they sent Sanji away directly.

He was also sent to Windmill Village.

Immediately afterwards, Ningchuan went to Xiluobu Village again and found Usopp.

……

In the end, Ningchuan gathered all the members of the Straw Hat Pirates in Windmill Village.

If Ningchuan had not come to this world.

Then these talents should be the protagonists of this world.

However, the world has changed.

Their fate also changed.

Ningchuan wanted to easily integrate the pirate world into his own body.

He was still prepared to send away these guys who could influence the world's consciousness.

"Is everyone ready?"

Ning Chuan stood in front of them and asked with a smile.

"Next, we will go to a powerful world together to practice."

"You will face a brand new challenge, but this will also be an opportunity for you to become stronger!"

The members of the Straw Hat Pirates nodded one after another, with excitement glittering in their eyes!

"Let's go then!"

Ning Chuan waved his hand and opened the space door leading to the one-punch world.

Over there, Karp and others were ready to receive these "newcomers".

Ningchuan believed that with the presence of Garp and others, there was no need for him to repeat the rules of the One Punch World.

After seeing these people off.

Ningchuan returned to Shuangyue Village again.

He also sent Kuina and her family back to the One Punch World.

Prevent them from becoming factors that influence the world's will.

After doing all this.

Ning Chuan got straight to business.

He plans to integrate the pirate world into his own body.

Together with the two worlds of Demon Slayer and Giant World, they merge into a new world!

As his spatial power quietly expanded, it began to spread throughout the entire pirate world.

At this moment, the sky became dark and the air was filled with a strong energy, as if all the space was foreshadowing this great change.

Ning Chuan closed his eyes slightly, muttered silently in his heart, and concentrated all his consciousness on his own spatial power.

He knew that this integration would be a huge challenge.

The world of one piece, as a huge and complex world, is larger in size than the world of attack on Titan and the world of demon slayer.

Take it into your body.

It is much more difficult than integrating the Demon Slayer world and the Titan world.

With Ning Chuan's thought, the power of space began to spread wantonly in the pirate world.

It was as if an invisible thread was pulling the whole world. Every inch of land, every ocean, and even every island floating in the air was under Ningchuan's control.

The sky of the pirate world seemed to be torn apart, the space fluctuated violently, the stars appeared and disappeared, and vortex-like energy raged between heaven and earth.

Suddenly, a powerful shock wave swept across, and the entire pirate world seemed to have undergone drastic changes under Ningchuan's control.

The mountains and the earth shook, huge waves rose in the ocean, and all the creatures in the pirate world seemed to sense something unusual.

All those scenes that we were used to seeing became strange in an instant, as if we had entered a whole new dimension.

However, Ning Chuan's mood was unusually calm, his gaze seemed to penetrate layers of fog, staring at the distant unknown.

As his spatial power further expanded.

The entire pirate world began to flow into Ningchuan's body.

It was as if a vast world gradually merged into the endless depths of his spirit.

Time seemed to freeze at this moment, and the whole world began to undergo qualitative changes.

Finally, with the impact of the last wave of energy, the pirate world completely merged with Ningchuan's body.

Ning Chuan felt an unprecedented power surging into his body.

That power was vast and complex, as if it contained the soul and origin of the entire pirate world.

Ning Chuan slowly opened his eyes with a satisfied smile on his lips.

The pirate world has successfully become a part of him and a part of his power.

But this is only the first step.

Next, Ningchuan began to merge the Pirate World with the two other worlds in his body, the Demon Slayer World and the Giant World.

This time the process went relatively smoothly.

Because these two worlds had already come into contact with Ningchuan's body before, the fusion between them became smoother.

Ning Chuan's consciousness quickly intervened.

Relying on his extremely powerful force of space and control over the origin of the world.

He effortlessly blends these three worlds into a greater whole.

When the final puzzle piece fits perfectly.

Ningchuan's body seemed to have turned into a huge universe.

It encompasses three worlds that once existed independently but have now merged together.

After the fusion was completed, Ningchuan once again felt the power of the origin of the world.

But this time he felt the original power of the world.

It is more than ten times the previous fusion of the giant world!

"Ten times the original power..."

Ning Chuan whispered, feeling the fluctuation of power in his body.

Then he just spoke softly.

"System, start settlement!"

[Congratulations to the host for successfully coming into contact with the world's original power for thirty minutes and activating the ten thousand times return system! ! ]

[Start practicing now! ]

[Solution successful, congratulations to the host for successfully obtaining the return of 300,000 minutes of cultivation for contacting the power of the origin of the world! ]

[The host has successfully used the power of the world's origin in his body! ]

Ning Chuan was a little surprised when he heard the voice of the system!

This time after the fusion of the pirate world.

He has actually been able to successfully use the power of the world's origin!

This surprised him a lot!

"Now that I can use the power of the world's origin, I want to see what this power is!"

In order to uncover the true nature of this power, Ning Chuan decided to conduct an experiment himself.

He calmed his mind, gently waved his hands, and began to absorb a small portion of the world's original power from his body.

Ning Chuan could feel that this energy seemed to have endless vitality.

Ningchuan only used a little bit and could feel the drastic changes it brought.

At this moment, his senses seemed to break through the constraints of space, and the scene of the entire triple world slowly unfolded before his eyes.

Every corner, every inch of land, and the existence of every living being seemed to be reflected in his heart.

This force is not simply energy, but an original force that can reshape the rules of the world and even create life and objects.

It grants him almost endless creative power, able to generate any existence that already exists in these three worlds out of thin air.

He can create any kind of Devil Fruit out of thin air, and even give it all the abilities of the original one!

Whether it is the ever-changing fruits or those combat fruits with powerful power, they can be easily born in his hands.

Not only that, this power can even give a person any of the three colors of domineering.

This instantly raises its combat effectiveness to an extremely high level.

What is even more shocking is that this original power of the world can also give birth to new beings.

Ning Chuan realized that he could even create a new monster worm and a new Demon King Muzan!

"This power is worthy of being called the power of the origin of the world!"

Ning Chuan muttered to himself, a hint of surprise flashed through his mind.

"Now, I need to find a place to test my guess!"

Soon, Ning Chuan returned to the One Punch World and called Hancock to his office.

Hancock heard that Ningchuan was looking for her.

Without any hesitation, she rushed into Ningchuan's office and wrapped herself around Ningchuan like an octopus.

"Hey, Ningchuan, did you miss me?"

"Let's get down to business..."

Hancock hadn't finished speaking yet.

Ning Chuan simply reached out and covered Hancock's mouth.

"Don't be in a hurry, do a little experiment!"

Ning Chuan said this with a smile, and directly took out the world's origin power that he had just absorbed from his body.

Then, in Hancock's shocked gaze, he directed this force of the world's origin onto her body.

This time, Ningchuan intends to make a radical change to Hancock's entire body!

He infused the original power of the world into Hancock's body, directly eliminating the side effects of the sweet-sweet fruit in her body.

The moment when Ningchuan eliminated the side effects of the devil fruit.

Hancock immediately felt a warm power flowing through her body.

At this moment, it seemed as if the shackles that bound her disappeared!

But Ningchuan's operations did not stop there.

He began to use the power of the world's origin.

The restriction that only one devil fruit can exist in Hancock's body has been lifted.

Hancock once again felt a shackle in her body disappear!

Just when Hancock was full of doubts and wanted to ask Ningchuan what was going on.

But she heard a voice that surprised her greatly.

"Hancock, you still have a lot of the original power of the world in your body. What other devil fruit ability do you want?"

"Just pick any dozen or so!"

Hancock: “???”
