Kill Me More Times, I'll Become Invincible - Chapter 378:

Travel to the world of One Piece?

They come, the security;

Became Don Quixote Rossindi?

Forget it, it can’t be reopened;

But after realizing that he had eaten the fruit of silence, the little boy became restless.

Fruit of Silence, this is one of the devil fruits that can compete for the title of “the most useless” in the world of One Piece; it is only a little better than Chopper’s “Everyone’s Fruit · Common People’s Form”!

“Dover, you said you are a devil fruit wholesaler, why do your family eat all kinds of weird ones?”

Facing the bewildered little Dover, Rossindi patted his forehead.

“Forget it, let’s practice domineering hard.”

- Description from novelbuddy

A young man with an extraordinary mind is off on an exciting adventure when he mysteriously wakes up in the body of a feeble slave-guy in a different, rich in quirks world.

The main character, a selfish jerk, would use extreme means to achieve his goals. However, he never allows his base instincts to overrule his sense of decency. He always pays back both good and bad deeds.

Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?

Parents dead, clan exterminated, body burned, hands mutilated, inflicted with innumerable diseases, tossed into the dump, and even the magic ring with the ghostly grandpa in it has been sabotaged. A reasonable person would roll over and die. Tian isn't that reasonable. And as it happens, neither is Grandpa Jun. A very tough kid meets a very cunning old man. And together, they will shake the heavens. What to expect:-1 chapter a day M-F. Volume 1 is already complete.-2k words per chapter (aprox, some run long) with a longer first chapter.-No Harem-Earned power growth-An MC who isn't a goodie two shoes OR an edge-lord psychopath-A power system based on actual Daoism -Sects, giant monsters, natural treasures, flying swords, spells, talismans, secret arts, and a gentle sprinkling of young masters whose face need rearranging.
