Lin Mo was originally a half-baked Maoshan Taoist priest who was so poor that he had to pay for instant noodles on credit. His Taoist teachings were all based on talk and bad ethics. He would always avoid him if he saw him - because he was blacklisted by the underworld. It wasn't until Su Qingyuan, the cold-blooded academic master, came to his door with a sky-high price to exorcise ghosts that he was forced to get involved in a series of strange incidents: a woman in red on campus, a corpse raising ground in a mountain village, props in an Internet celebrity haunted house... Each case contained clues to the civil strife in Longhu Mountain, and Su Qingyuan's extremely yin physique was actually the key to unlocking the seal in his body. The two went from being enemies to becoming life-and-death partners. While using their coquettish tactics to scare off evil spirits and get money to pay off their debts, they also uncovered the conspiracy of the mastermind behind the scenes to open up the Yin-Yang channel. As the seal was gradually lifted, Lin Mo's true face of "Ghost Seeing Sorrow" shocked the three worlds. Finally, he teamed up with Su Qingyuan to establish a ghost exorcism agency that made the underworld tremble, proud of both the Yin and Yang worlds.
