Interpol Pei Chao is ordered to investigate a series of serial murders that use ancient sacrificial totems as clues. Each corpse is placed in a strange ritual, and the death state is exactly the same as the "soul sealing technique" that has been lost for thousands of years. Following the lead, he found the only insider - folklore researcher Shen Zhou.
The two of them encountered something they had not expected in a forbidden ancient temple.
Overnight, souls were exchanged.
Pei Chao was trapped in Shen Zhou's body and saw the "ghosts and gods" he had scorned; Shen Zhou fell into Pei Chao's body and came into contact with the darkness of human nature that had been deliberately buried. Two bodies, two memories, and two completely different world views collided savagely in the same conspiracy.
They must cooperate - use each other's identity to find out the bloody secret that spans thirty years, find out the mastermind behind the "soul exchange" method, and also find the soul that truly belongs to them.
But in the process, they gradually discovered that some things are more terrifying than soul-changing.
That is - there are people who don't want to change back in the first place.
