High Martial World: Eighteen and Already Past My Prime?

Lin Lei spent eighteen years as the world's most unremarkable student in a high-martial academy—no cheat abilities, no talent, just an expulsion notice waiting to be signed. But the moment he accepts his fate as a failure, the Counterattack System awakens. There's just one problem: the system thinks he's middle-aged. Now armed with power that defies logic, Lin Lei transforms from academy dropout to legend. When the abyss opens and its apocalyptic lord threatens to devour everything, he's the only one crazy enough to charge straight into oblivion. Geniuses? They all bow to him now.
