I the King of bandits of the East Sea Novel

After transmigrating into Sig, the Bandit King of the East Sea, the protagonist finds himself in immediate danger—having just smashed a bottle over the head of Red-Haired Shanks, one of the fearsome Four Emperors. Desperate and panicking, he must figure out how to survive this catastrophic situation. His salvation comes in the form of an unusual role-playing system that grants him the abilities of whatever character he portrays—the better the performance, the stronger he becomes. Unfortunately, his first character card is King from One Punch Man, an S-Class Hero notorious for having absolutely no combat skills despite his intimidating reputation. Now forced to bluff his way through the treacherous waters of the East Sea, the protagonist must convince everyone around him that he's powerful enough to casually assault the Four Emperors, all while possessing none of the actual strength to back it up.
