The world became a living hell for five long years. Chen Yan could only watch in helpless agony as his sister, already afflicted by a deadly poison, was brutally slain by monstrous beasts.
But when he opened his eyes again, he found himself reborn five years into the past, before the apocalypse began—and gifted with extraordinary powers.
Then, the System arrived, presenting him with a path to save his sister. There was only one condition: he must relentlessly increase his strength and level up like a man possessed, for his true mission is to prevent the apocalypse itself.
