You are the last line of defense for a city, but no one knows your name.
On a rainy night, college student Chen Chi encounters a “taboo” at the last bus stop. His uncle, whom he has never met, saves him by trading his own life for Chen Chi’s. From then on, Chen Chi is drawn into the world’s hidden side: the Nightwatch Bureau, an organization of night sentinels who mark themselves with carvings and patrol with blades in hand. Three hundred Forbidden Hollows lurk in the darkness, seven King Hollows covet the mortal world, and three Divine Hollows watch over humanity. Under the guidance of the stern instructor Jiang Ning, Chen Chi steps onto this path, only to discover that his very existence is the final variable left behind by the first generation of night sentinels: a fateful point destined to be forgotten by every timeline.
When night falls, I carry a blade, not an umbrella.
