When the eternal night fog swallows 70% of the world, the shadow is no longer a vassal of the light, but a living creature that chooses people to eat.
After the "Year of Shadows" in 2035, ordinary people who are exposed to the mist for more than five minutes will be assimilated by shadows. Only the awakened ones can use shadows to make shadows - they condense "Shadow-Eating Blades" to kill monsters, but the price is the "shadow pattern" that spreads on the body surface. The day the patterns cover the heart, it is the time to become a shadow puppet.
Lin Shen, a makeup artist at a funeral home, can see through the essence of shadows with his left eye and freeze his actions with his right eye. When he was eight years old, he witnessed the shadow of his mother being swallowed by the "Mirror Ghost", which caused him to seal his abilities for three years. Until a female corpse was brought back in the mist, forcing him to regain his power: the shadow of his left hand turned into a liquid blade, but the fingertips were carbonized at a speed visible to the naked eye.
He was forced to cooperate with Su Wan, a member of the mysterious organization "Light Eclipse Council", who could weave "memory mazes" but forgot fragments every three days; he traveled with Amir, who was a host in the "Ganges Shadow", whose skin was calcified like stone, except for the third eye between his eyebrows. They are fighting against not only the "Subway Ghosts" and the "Confucius Temple Night God" and other shadow creatures that claim their lives according to strange laws, but also the high-level members of the parliament who are trying to sacrifice five billion people in order to gain hegemony, and the shadow king Azathoth who sleeps in the center of the earth and is the embodiment of mankind's collective fear.
The truth about his mother's death was hidden deep in the mist. The stinging pain from the shadow pattern crawling across his neck reminded him day and night that the time limit was approaching. And every seven days when the mist became crazier, the time and space rifts of historical horrific scenes were dragging the world into a darker abyss. This gamble at the cost of flesh and blood starts from the freezer of the funeral home...
