Ling Xiao travels through the West, and possesses the Monkey King, who is crushed by the Five Elements Mountain. His cultivation is wasted by copper juice and iron pills every day, and his fate of becoming a puppet of Buddhism is imminent. In a desperate situation, he activates the daily sign-in system. He has been dormant for five hundred years, and has accumulated sign-ins to unlock heaven-defying rewards such as the Nine Revolutions Mysterious Art and the Chaos Immortal Body. At the expiration of five hundred years, he overthrew the Five Elements Mountain and reached the pinnacle of quasi-sage cultivation. Since then, he has been on a journey to the west, rewriting the Buddhist calculations, controlling his own destiny, and becoming the ultimate boss that no one dares to mess with in the three realms!
