A Hundred Millionfold Boost from the Start: One Punch to Destroy Impel Down

Ross never imagined he would transmigrate into a cell in Impel Down.

Luckily, he awakens the Infinite Enhancement System just in time.

A billionfold boost to everything!

Garp: “My grandson, if only you'd listened to me back then, things never would have come to this!”

Ace: “Grandpa, I'd rather die than become a Celestial Dragon's *!”

Ross: “You two, stop chatting nonsense and hurry up and let me, an innocent and kindhearted man, out of here! Otherwise, I'm afraid I'll lose control and punch this whole prison to pieces!”
