At the beginning of chaos, Xuan Xiao, the Thunder Demon God, understood the fate of the destruction of three thousand demon gods. He helped Pangu create the sky, but he was backlashed and his soul was scattered. Fortunately, Pangu used his supreme power to protect his remnant soul from being reincarnated into the wild world, and even passed down the power of robbery and punishment. Since then, Xuan Xiao was born in the wilderness, taking charge of tribulations and punishments, ignoring the game of saints, acting erratically, making thousands of living beings afraid, vowing to reverse fate and stir up the chaos in the wilderness.
