(Note: You don’t need to understand Gu techniques to enjoy the story, the protagonist’s Gu are all based on elements from the Naruto world.)

Fang Yan transmigrated into the Naruto world, expecting the usual protagonist treatment:

Admiring beauties? Bonds of friendship?

What he got instead was the surgeon's scalpel in the Root laboratory and brutal death training.

His only lifeline, were the Gu worms inside his body.

To survive, Fang Yan must stop at nothing.

Friends? Heroines?

They’re nothing more than fodder for refining Gu!

He devours Root. He devours Konoha.

He devours the entire Shinobi world.

“Fang Yan, you’ve gone astray. It’s not too late to turn back!”

But just when everyone believes the battle is over, Fang Yan raises a single finger and shatters every illusion.

“Turn back? I, Fang Yan, have never done a single thing wrong in my life. Why would I repent?”

In that moment, all the cocoons on the battlefield burst open

A flood of chakra from ten thousand bodies surges into Fang Yan.

“A raft of blood sails the River of the Dead,

A thousand corpses form a ladder to the heavens.

Ten thousand Gu devour my soul, yet I have no regrets.

I will prove the Gu Dao and defy the heavens themselves.”

In the mass grave, I fed a ghost alive - it was just a tool for me to survive.

The essence and blood of the clan members, the flesh and blood of geniuses, the souls of the entire clan... all become food for refining ghosts!

The stronger the ghost, the more ferocious the backlash? Stronger restrictions, deeper calculations, make it a permanent slave!

They used every possible means, including robbing cultivators, massacring cities, going undercover, killing masters, and training devils.

My evil magic reaches all the heavens, and I use the common people as materials to refine my supreme ghost way!

Foundation Establishment, Golden Core, Nascent Soul… In front of the world barrier, looking back:

Homeland? It's just the first stepping stone to the top!

The world is nothing but a game played by the gods.

And goblins? Seen as the weakest, filthiest creatures—worthless pawns in the eyes of every race. Just disposable playthings in the hands of the divine.

But today…

An Outer God descends, blessing the goblins with unholy power.

Now, it’s time for the other races to witness the true horror that goblins can unleash!

We are not your pawns.

We are not your toys.

We are your reckoning.

Gu Shanhai saw the great world of the heavens, and took the life of the third life.

The gods of the world forged an eternal Utopia with blood and fire.

The Red Dragon King led his knights to inspect the dynasty on which the sun never sets.

Scholars talked and laughed and swung their swords to draw thousands of miles of rivers and mountains, and strange demons opened their eyes and clawed to give birth to ghosts and monsters.

…

“Everyone is a player, you can’t call me abnormal because I don’t have digitization?”

After traveling through Under One Person, Xia Ye awakened his innate supernatural powers.

Analyze all things, extract the essence, develop miraculous medicine, bring the dead back to life and turn bones into flesh, shed old bodies and grow immortal feathers.

Starting from a secret strange medical clinic, the world gained a miracle doctor who could cure all diseases...

and under the cover of night, the corpses of countless evil thieves.

Since Xiao Zizai lost control, the process of life evolution began:

Subject 001 - Asura

Subject 002 - Pharmacist Liuli

Subject 003 - Empress of Qingqiu

...

Countless legends have come to the world, and immortals and gods have appeared!

Through repeated experiments, Xia Ye mastered the secret of reaching the sky, experienced transformations again and again, and turned the human world into a divine realm.

"Everyone, abandon your old skin and welcome the advent of the new era with me!"

Can you survive in this cruel world?

"This is a world that is broken and stitched together. It is said that everything is there."

"Yeah, there's order, but not much, just a little bit."

"Travelers are not worth anything in this world."

"A few groups come regularly every year, and they are said to be time-traveling refugees."

"In this case, we have to hide our special identity, otherwise we will be beaten when we see it."

"If our special ability is exposed, it will directly become a 'peerless treasure' that will be coveted."

"So, main body, please work hard. Whether we live or die, we all depend on you."

"Shut up."

Wan Yi quieted down the countless figures with faces similar to his around him.

In this way, he will perform the drama of "one person" in this world and in that wonderful theater.
