Light Chaser: Red Redemption

Lin An, the former Sanctuary law enforcement captain, was betrayed and killed by his beloved Ye Wanqing ten years after the end of the world, and was reborn three months before the pollution outbreak. Carrying the system and memories of past lives, he vowed to uncover the truth behind the Sanctuary's creation of the apocalypse, but discovered that he was actually the "perfect prototype" for genetic experiments. "When the world feeds on betrayal, only those who live toward death can create a new dawn." - Lin An
