I Actually Became White Impermanence

Once the First War God of the Netherworld, he reincarnated as an ordinary High School Student. But as the gears of Fate turn, when the Heavenly Dao collapses and evil descends upon the world, he must wear his armor once more. Under the guidance of the aloof Goddess Black Impermanence, he will fight the Five Directional Ghost Emperors and battle the Ten Yama Kings. The King Returns to conquer the Three Realms, dominate The World, reshape the Cycle of Reincarnation—Only I Am Supreme!
