Yang Xuan transmigrated and entered the underworld after death, obtaining a check-in system. Checking in at Fengdu City, reward: Underworld Scripture; Checking in at the Wheel of Rebirth, reward: Wheel of Rebirth Dao; Checking in at the Eighteen Levels of Hell, reward: Millions of merits. Yang Xuan, knowing the dangers of the world, hides in the underworld and checks in everywhere. After thousands of years, Yang Xuan suddenly discovers that he has become a Saint. The Jade Emperor of Heaven: Yang Xuan, as fellow Daoists, what's the meaning of you suddenly coming to my Heavenly Court to hook my soul? The Western Buddha: Yang Xuan, although we are not of the same sect, is it appropriate for you to hook my soul to the underworld for deep-frying? Our Buddha's Ksitigarbha Bodhisattva is still working in the underworld. Yang Xuan: Sorry, I have the final say in the underworld from now on.
