I Fought My Way Through Everything, and Now You Say I’m the Prophesied Savior?

(This story features: no System + no female lead + lighthearted comedy + a touch of darkness + a touch of playing the pig to eat the tiger + a touch of frailty) A prophecy foretold two children, one who would save the world and one who would destroy it. But which one was the savior? And which one was the destroyer? Don't panic if you transmigrate into someone who's about to die. Maybe Heaven is jealous of talent. Maybe you'll awaken a one-of-a-kind ability. Unfortunately, the person He Yan transmigrated into had been designated the world's destroyer in that book. With such a huge burden dropped on him, it was lucky his spine was strong enough to bear it. He'd even do a better job than the character in the book. A label? He didn't need the world to define him. What right did a character in a book have to define him?
