Legacy Of The Extra - Chapter 22: Progress(2)

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

Jun Ye travels through worlds for unexplained reasons and is always cast in subservient roles. Unfortunately, that wasn’t his style. Let the counterattack commence!
