In 1520 of the Sea Calendar, the Battle of Marineford broke out, and the Yi Chen Grand Fleet descended from the sky, surrounding the entire navy.

Crocodile: Boss, did you have to make such a cool entrance?!

Empress: I will protect Brother Chen's will!

Ming: Young Master Chen, let's cause a huge ruckus together!

Moonlight Moria: ......

Life Healing, Spider Sense, Baji Grandmaster, Innate Power, The Golden Rule...

Looking at all these things signed in through the system, Bai Yunshen felt helpless.

What a useless system! They were all good things, but what good were they in this Saint Seiya world, where gods abound and gold is worth less than gold? In this world where the microcosm is the cultivation system, mastering the sixth sense to attack at the speed of sound and the seventh sense to attack at the speed of light is of no use! And then, until one day...

Congratulations to the host for signing in to [The Nature of Regulus]! So good...

(PS: This book is primarily based on the Saint Seiya world, with passages into other worlds.)

The cold-hearted Li Xuan brought the sign-in system to the main god space of another world. Compared with other reincarnations, he has the ability to be familiar with the plot.

"Li Xuan is the strongest breathing swordsman in history!" Lord Ubuyashiki Yoya praised him at the Pillar Meeting.

......

"He actually dragged Muzan out to bask in the sun!" The pillars were shocked.

"Why is it so difficult to stop it from being cut?" Li Xuan said to Wuzan, who was stunned and whose life had lost its meaning.

......

In the Sword Art Online world, he directly broke through the 100th floor, and even the GM couldn't stop him.

During the Battle of Marineford, in order to improve his reputation, he beat up the three admirals of the navy, the Whitebeard Pirates, and the Red Hair Pirates.

During the Fourth Shinobi World War, he beat Kaguya like she was bullying a child.

In the Curse War, he used all the spells on himself to eliminate all the weirdness in the world.

Time passed in the blink of an eye, and he stood above all the reincarnations.

On the night of the genocide, Sasuke awakened his memories of his past life.

He knew about his past and present lives, and understood the history of the ninja world.

He also activated a cheat code that allowed him to travel to other worlds every three months.

So he made a bold decision...

"I want to drop out of school!"

Sasuke slammed the application form in front of the Third Hokage.

The purity of ninja is too low. Who would want to do such a sunset profession?

If you want to be rich, be a noble, and marry a princess.

Vigorously develop the business and entertainment industries, and extend its tentacles to every corner of the ninja world.

What? You said Konoha doesn't agree?

"You don't need to agree. I'll do it myself. I want to build a new Konoha!"

At the same time, we use technology from other worlds to create various new ship professions.

Psychics, Ninjutsu Swordsmen, and the Quincy...

When Sasuke came to his senses, he had already unified the ninja world and became the richest man in the ninja world.

However, this was only the first step in his quest to dominate the heavens.

When the souls of 21st-century youths merge with Luffy's, the world begins to change! He bravely battles crocodiles in Alabasta, confronts his nemesis in Mogu'town, and challenges gods on Skypiea… (The synopsis is insufficient; please read the full text.) Multiple female leads + fast-paced, action-packed story + plot summary: The first few chapters are virtually identical to the original manga! If you remember the manga, you can skip directly to the fight against Crocodile; the previous chapters are simply a recap of the original. The only advantage is that you can watch at least 50 minutes of plot in 5 minutes!
