The day after the Four Realms Conference ended, an unexpected visitor came knocking.

In Yechuan’s study, Alabasta Palace.

Nefertari Vivi, the princess of Alabasta, stood alone and calmly before Yechuan.

She had changed out of her gorgeous princess gown and into a more capable and simple white robe.

The softness of the past had faded from her beautiful blue eyes, replaced by a trace of kingly resolve and determination.

“Yechuan-sama.”

She performed a standard royal bow to Yechuan, then got straight to the point.

“I can no longer exist merely as a royal protected by you.”

“This country, this world, is changing at an unprecedented speed in your hands.”

“I want to learn, I want to participate, I want to know how to manage such a vast empire.”

She looked at Yechuan, her eyes filled with undisguised sincerity and longing.

“Please… give me a position, allow me to serve you.”

Yechuan looked at the princess who was actively asking to transform from a canary into an eagle, and for the first time, his purple Rinnegan showed a hint of surprise.

But then, this surprise turned into admiration.

He slowly stood up and walked to Vivi, the distance between them closing to the extreme.

He reached out and gently lifted the girl’s smooth chin with his finger, forcing her to meet his gaze.

“Very good, Vivi.”

A playful curve appeared at the corner of Yechuan’s mouth.

“I see your resolve.”

Vivi’s cheeks instantly flushed crimson from this sudden intimate gesture, but she did not flinch, still bravely looking back at him with her clear eyes.

“From today, you will serve as the deputy to the Empire’s Advisor, Robin.”

Yechuan announced calmly:

“I will have her personally teach you how to handle the Empire’s economy, internal affairs, and the dark order hidden beneath the light.”

“Don’t disappoint me, my Princess.”

…After settling Vivi’s matter, Yechuan stepped through the Gate Between Worlds that had already been established, and his figure instantly appeared inside the Golden Ark Maxim, which was suspended ten thousand meters in the sky.

This place had been transformed by him into the Empire’s most core scientific laboratory, closely connected to the One Piece World’s Egghead Island, Future Island, through another Gate Between Worlds.

“My Lord! You’re finally here! A great discovery! This is simply the greatest discovery since creation!”

As soon as Yechuan appeared, Vegapunk’s apple-headed figure excitedly rushed over, waving a report filled with complex formulas!

“Chakra, Cursed Energy, Magic Power… My Lord! These energies from different worlds, their essence is interconnected! They are all different manifestations originating from spiritual and life origins!”

He pointed to a giant holographic projection in the center of the laboratory, which displayed 3D structural models of the three energies at the molecular level.

“As long as we can find the singularity of their conversion! We can even create an ultimate life form that can be compatible with and use all energy systems!”

He looked at Yechuan, his eyes gleaming with the characteristic fanaticism of a scientist.

“For this, I proposed a brand new plan — the Hybrid Soldier Project!”

“We will re-modify the Ultimate White Zetsu you created!”

“Not only will we implant green blood into them, allowing them to use Wood Style and Tremor-Tremor Fruit powers, but I will also implant a Magic Core into each of them!”

“Allowing them to use basic elemental magic, just like the Mages of the Fairy Tail World!”

“Not only that!”

Yechuan looked at him and smiled.

He slowly raised his hand, and a white-haired man with hollow eyes, pierced by a black rod, slowly appeared.

It was Gojo Satoru, whom he had made into the new Human Path.

“This material, possessing the ultimate analytical ability for energy, is also given to you.”

Yechuan said calmly:

“I hope you can integrate his Six Eyes and Limitless into our new weapon as well.”

“Six… Six Eyes?!”

Vegapunk looked at the man’s azure eyes, which seemed to see through the truths of the universe, and his apple-head trembled violently from extreme excitement!

He fell to his knees with a “thud,” prostrating himself before Yechuan, letting out a fervent cry!

“As you command! My Lord! I will surely create the most perfect soldiers for you!”

…After completely planning the Empire’s technological development blueprint, Yechuan knew it was time to assign new tasks to the legendary combat forces under his command who had been idle for a long time.

He returned to Alabasta and gathered Hashirama, Tobirama, Madara, and Whitebeard in the villa specially prepared for the Impure World Reincarnation users.

“First Hokage-sama.”

Yechuan first looked at Senju Hashirama.

“The Jujutsu Kaisen World is barren and its inhabitants are suffering due to the pollution of Cursed Energy.”

“I need you to go there, use your Wood Style power to purify the land, and bring new life to that world.”

“Oh, oh, oh! Leave it to me!”

Senju Hashirama immediately slapped his chest in assurance, excited at the mention of planting trees.

Yechuan then looked at Uchiha Madara.

“Madara, you crave war, you crave powerful opponents.”

“I will establish a War Academy for you, with you as the Chief Instructor.

You will pass on your tactics, your dominance, everything about you, to the new generation of White Zetsu commanders.”

“Hmph, training a group of puppets who only obey orders?”

Although Uchiha Madara spoke with disdain, a flicker of interest flashed in his Eternal Mangekyō Sharingan.

Finally, Yechuan looked at the strongest man in the world, who had remained silent throughout, simply drinking his sake.

“Whitebeard.”

“Gurarahahaha… Speak, brat.”

“The sea needs a new order.”

“You will be stationed on the New World shipping lanes; your presence will be the greatest deterrent to all scoundrels.”

“Protect my family, protect my shipping lanes.”

Whitebeard heard this, remained silent for a long time, finally drained the strong sake in his bowl, and slowly stood up.

“…I understand.”

He hoisted Murakumogiri, which had returned to his hands, said nothing more, turned, and strode out of the villa.

As for Senju Tobirama, Yechuan continued to send him to the Jujutsu Kaisen World, where he would be responsible for establishing an absolutely efficient administrative system with his iron-blooded laws.

Thus, Yechuan’s four most powerful legends, like four sea-stabilizing divine needles, were strategically placed in various corners of the Empire, laying the most solid foundation for the stability of this nascent Empire.

And he himself could finally rest assured and deal with the last matter.

It was time to exchange for a new Gate Between Worlds and open the next world.
