Quanzhi Juexing

Elias Bai, Captain of God's Legion, stood as the world's strongest Awakener until a brutal betrayal claimed his entire squad. Dying as a mere pawn of the ruling elite, he suddenly wakes up twenty years in the past—back in middle school, long before his awakening. With his loved ones still alive, Elias refuses to let history repeat itself. To save his team, exact vengeance on the traitor, and overthrow the corrupt system, he must walk a lonely road to unrivaled power.
