The place where he had knelt was now full of bones. The confession ceremony of former detective Xie Chen has become the coordinates of the death map; every autopsy report of forensic doctor Zhou Yan points to the same unrecorded kneeling posture. The old guard in the town burned paper and whispered, the mute Taoist priest swept the steps like a sacrifice, and in reporter Su Rui's tape recorder, there were seventeen deceased people writing in blood "He is still kneeling" before they died. When the seventh corpse knelt upright in front of the temple door, Xie Chen's leg bones began to mutate - he was not the murderer, but the last living sacrifice.
Xie Chen and Zhou Yan teamed up to investigate seven "Kneeling Death Cases". Each corpse was lying in the same position where Xie Chen had knelt. There were faded bronze symbols embedded in the corpse's chest, which exactly matched the notes left by Zhou Yan's grandfather. Lin Zhao deliberately leaked the secret passage of the cellar, leading the two to discover the corpses of seven children buried twenty years ago, while Zhao Baichuan took advantage of the launch of the town reconstruction project to try to dig out the core of the earth's veins. Su Rui's recording accidentally recorded Chen Yan's 'voiceprint' - it was Xie Chen's voice. The truth gradually emerged: In order to save his teammates, Xie Chen knelt down to bear the curse. His soul was split into seven pieces and scattered among the bones; for each person who died, a piece was replaced. Chen Ya's mission is to make Xie Chen kneel down seven times to seal the earth's veins with blood; while Zhao Baichuan wants to use the bones to refine the elixir of immortality. Zhou Yan found during the autopsy that his blood could temporarily suppress the curse, which meant that his grandfather had known that his blood could be the antidote. Xie Chen finally understood that what he was kneeling on was not a sin, but a life-saving lock. When the eighth corpse appeared - Su Rui fell on the stone steps where he had knelt, and a bronze talisman exactly like his appeared on his neck, Xie Chen raised his stump and slowly knelt down.
