Zhang Qingyuan, an ordinary deliveryman, took a midnight order to an unfinished building for a high delivery fee, but because of this, he got a ghost knocking on the door and was forcibly opened the "yin eye". From then on, the city that no one should approach was opened to him - the ghosts lingered and evil spirits whispered, and he became a living target of the yin and yang. When he was on the verge of collapse, Xuan Chenzi, a sloppy old Taoist, handed over a call from Maoshan: "Boy, you have been marked by evil magic. If you want to survive, go up the mountain." He was forced to step into the Taoist sect and apprenticed to his uncle, the naughty master, and Zhang Qingyuan's hard training began. Sweeping the floor to build foundations, painting talismans with cinnabar, standing on poles to draw energy... However, the dusty notes in the Sutra Pavilion revealed a deeper horror - what he experienced that night was not an accident, but an evil sacrifice for the "Tongyou Physique"! The shadow of the Yin Eye Altar and the curse of ancient symbols are closely followed. After half a year of hard training, I finally came down the mountain. The human world is also a purgatory, with mysterious live broadcasts, haunted houses in ancient towns, evil spirits in the mirror, zombies surrounding the village... Crises are coming one after another. But this time, he no longer ran away. Holding the talisman, reciting the mantra, and stepping on the sky. "The poor Taoist Maoshan is a pure source, but there are evil spirits ahead, can you dare to fight?" Let's see how ordinary young people inherit the Maoshan Taoism, slay demons and eliminate demons in the world of mortals, uncover many fogs, and finally shoulder the great responsibility of protecting the common people!
