At the same time, Xie Wujiu, the elite underworld commander, also came to the world to investigate the "Case of the Disappearance of Ten Thousand Souls". The two met because of a grudge ghost rampage incident. From mutual suspicion to being forced to join forces, they embarked on a suspenseful pursuit of the murderer that swept through the three realms. As the investigation deepened, they uncovered a shocking conspiracy: the collapse of the reincarnation system was not an accident, but someone behind the scenes was stealing souls in an attempt to subvert the order of life and death. Behind Meng Zhihui's bloodline as a tombkeeper, there is also an ancient secret that protects the law of reincarnation. She is not a bystander, but the core of this catastrophe. In the absence of a golden finger, she will use her extraordinary insight and courage as a mortal to work with Xie Wujiu to uncover the true murderer in the fog of heaven and hell and reshape reincarnation.
