Su Yi transmigrates to the world of One Piece and becomes the supreme Celestial Dragon.

I thought I had a perfect start, but I found myself to be a useless piece of trash, so weak that I would pant after walking just a few steps.

With Straw Hat Luffy about to set sail, the Revolutionary Army's anger is burning, the Celestial Dragons' "good days" are coming to an end, and he could become cannon fodder at any time.

In this moment of despair, the [Great Dao Demon Cultivation System] was finally activated!

Since Heaven won't grant it to me, I'll take it myself!

Since the righteous path is difficult to follow, then let us prove our path through demonic means!

To refine the [Innate Demonic Marrow Pill] that can defy fate and change one's destiny, one needs the brain marrow of one hundred "hundred-man slayer" villains.

Simple!

Su Yi, in the name of a Celestial Dragon, issued a single order and marched straight to Impel Down, the underwater prison.

"I want to 'borrow' one hundred of the most vicious prisoners to be my new 'toys'!"

Does cultivating demonic techniques require a highly wicked person as a catalyst?

Isn't this simpler?

Aren't all the Celestial Dragons in the Holy Land just like that?

[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!"
