On a rainy night in Jiangzhou shrouded in neon, an anonymous letter broke Lin Shen's peaceful life. In the yellowed photo, Su Tang, his fiancée who has been missing for five years, is wearing a ginkgo leaf necklace and smiling slightly while standing in front of an emerald lotus lamp. In order to pursue the truth, Lin Shen stepped into the undercurrent auction and bought the lotus lantern for a sky-high price of 8 million, but he did not know that he had been involved in a bloody conspiracy that spanned twenty years.
The jade lamp cracked and the smell of blood was overwhelming. Under the scalpel of forensic doctor Shen Nanzhi, Su Tang's curled up body was cut open. As the investigation deepens, cultural relic smuggling, black market transactions, and old cases gradually come to light like poisonous snakes spitting out letters. Behind the sinister smile of Zhou Zhenhai, the owner of Zhenbao Pavilion, lies the truth about the murder of Su Tang's mother. In the abandoned warehouse, dozens of corpses sealed in jade carvings tell the despair of the resisters.

However, the mysterious forces that have not been revealed in the account books, and Shen Nanzhi's complicated expression that hesitates to speak, imply that this bloody mystery is far from over. The emerald light is still shining in the dark, and new suspenseful clues are waiting to be revealed...
