Chen Mo, the down-and-out folk UP master, returned to the village to inherit the mysterious theater box left by his grandfather, and awakened the strange ability of the "folk custom taboo maker". He originally wanted to prove that "there are no ghosts in the world" in the live broadcast room, but was forced to become the guardian of the yin and yang order.
From punishing village bullies who violated taboos, to quelling the resentment of century-old red-clothed water ghosts, to sitting at the Huangquan Ferry to establish rules for the two worlds, Chen Mo gradually ascended to the position of the head of the "Human Night Watch Division". The violent village doctor Lin Xiaoxi and the cold-hearted investigator Qin Yao have become his sharpest sword and strongest shield.
When the local government is held accountable, the Thousand-Year Nightmare Gate attacks, and the collective fear of the entire mountain village turns into a shadow of annihilation, Chen Mo no longer slays demons, but chooses to go into the deepest depths of people's fears and stage a "human drama" to transform all sentient beings.
"I will never destroy ghosts. I will only make people in the world. There will be no new ghosts."
