As the blood moon rises, demons invade the earth. Wen Yu is reborn back to that apocalyptic day, and given the profession of Soul Master, with the power to summon hordes of spiritual beasts. On a post-apocalyptic Earth, he will hunt powerful monsters, experience the darkness of human betrayal, survive a hopeless war, while searching for… a faint ray of hope. (Source: Kuaikan, tanslated)
