Twelve years ago, my father led a team into an undeclared archaeological site and disappeared completely. He was classified as a defector by the organization.
Twelve years later, the Robbery Cave collapsed on a rainy night in Longji County, leaving an ancient black coffin empty except for blood mud and a bronze scale inscribed with "Guixu". In the surveillance footage, the tomb robber who was confirmed dead walked out of the scene on his own.
Chen Yan was forced to restart the old case. He enlisted Gu Nanxing, a scholar of ancient writing, Jockey Club, a veteran of the agency, and Ji Heng, a technical detective, to form a temporary team outside the system and find the Guixu Underground Palace before the tomb-robbing organization "Fog Lantern Club".
But what is sealed in the underground palace is not treasure—but an ancient disaster that could destroy the city.
The tomb guard girl Ahe is the only key that can activate the seal, at the cost of her own life.
Thirteen gates, each one has to hand over real pain.
The fourteenth gate is not recorded in any literature.
