Extra And MC - Chapter 40 - 37.5 - Fun

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.

Su Yang was an average university student in Shanghai when he received a system that allowed him to add points to things. The point system provided him with missions and by clearing them, he would gain points.
