(Naruto fanfic + Gu cultivation + No system + No heroine + Dark theme + Extreme self-interest)

(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.”

[Evil Garp + villain + cool story + lots of + cool battles + invincible + anime! ]

Lin Yi traveled through time!

The good news is that he has traveled to the pirate world that he is familiar with!

The bad news is that he traveled through time and space and became the old man Garp!

The good news is, he has a system!

The better news is that this system is a villain system!

……

Lin Yi: "Although I have traveled through time and space and become an old man with not many years left to live, killing people can take away everything from the enemy, and I can also obtain the origin of the world to buy items from other worlds. From this point of view, it feels pretty good!"

"Hmm? The time of traveling back in time is still the early stage?"

"How about... starting with my good grandson Luffy?"

"The Nika Fruit is still very powerful!"

[Villain] [Hell Starts] [Behind the Scenes] [The Money-Giving Monk] [No Female Lead] My name is Lone Star. I am naturally heartless and a lonely star. A good assassin must know how to take advantage of other people's weaknesses, and the greatest weakness of human beings is emotion. The third rule of the assassin's code: Never intervene in other people's affairs outside of the mission. After fifteen years of killing and scheming in the other world, Lone Star established the world's strongest assassination organization and became the king of the underground in the other world. As long as the price is right, even if it is the ceiling of combat power, Lone Star will calculate and take action. Until this day, Lone Star received the task of assassinating Emilia, and the gears of fate began to turn, but with the intervention of Lone Star, will the plot be the same as before?
