Xiao Leng is the last generation of orthodox night watchmen in China.
The Xiao family has been nameless and short-lived for generations. They do not go to the fairy gate or enter the court. They only rely on a copper lamp to keep vigil and a three-foot evil-cutting dagger to guard all the ghost lands in the world late at night.
Revenant ghosts in the mirror, water ghosts in rivers, taboos in mountain villages, unjust marriages and unintended deaths... Countless folk customs and sinister disasters have appeared one after another in the bustling city, and people are sleeping soundly without knowing how to kill in the middle of the night.
The Ghost Division of the Dragon Group initially regarded him as a high-risk evil cultivator. After several trials and confrontations, they realized that the young man was responsible for the darkness of the entire city alone.
The evil cultivator of willow bones steals the yin and refines evil spirits, the ghost clan from outside the territory covets the Chinese dragon vein, and Mo Yuan, the source of eternal darkness, waits for the opportunity to swallow up the fireworks of the world.
Xiao Leng traveled alone through the mountains and rivers, gathering craftsmen from western Hunan, fishermen from the Yellow River, and folk descendants of the Zhongnan Trail. They burned copper lamps to awaken the phantoms of their thousand-year-old ancestors, and used their mortal bodies to build a defense line in the world.
The world does not know the sacrifice of the nameless night watchman, only that he sleeps peacefully and the lights are always on. There is no love brain, no systematic cultivation of immortality, only the tragic and passionate story of a mortal protecting the country and standing alone at night!
