Talent System: I Instantly Master My Opponents Skills - Chapter 20: Offhand

Kai is the hardest working warrior in his generation... and the unluckiest. In a world where most people receive magical skills, classes, or cultivation, Kai has nothing but his wits and his strength. His only choice will be to forge a new path against fate, no matter where it takes him.

Savage monsters pour endlessly from the wasteland, threatening the survival of civilization itself. They say that human strength isn't enough and only those gifted with destined powers have a chance of making a difference. Kai is hungry to fight in that war, to be someone who matters. That hunger will take him across a world stranger and more terrible than he could possibly have imagined.

With the ability of the King of Silver, the first king in “K”, to be immortal and immortal, he crossed into the world of One Piece. Although he became a Pirate, he did not target One Piece.

His goal is to live freely on the sea, it’s that simple.
