You are a city's last line of defense, but no one knows your name.
Chen Chi, a college student, encounters a "taboo" at the last bus stop on a rainy night. He is saved by an uncle he has never met before, who sacrifices his life for his life. From then on, he is involved in the backside of the world - Chang Yesi, a night watchman organization that uses carvings as its seal and carries a knife at night. Three hundred banxu lurk in the night, seven kings covet the world, and three gods overlook the world. Chen Chi embarked on this path under the guidance of the cold instructor Jiang Ning, only to find that his own existence itself was the last variable left by the first generation of Night Watchmen - a destiny node destined to be forgotten by all timelines.
When night falls, I carry a knife instead of an umbrella.
