Taibai Jinxing discovered that a force that was not within the control of the Three Realms suddenly appeared in the world. These people were immortal, indestructible by water and fire, and their names were not in the book of life and death. The Jade Emperor suspected that there was a traitor in the underworld, so he set up a Yin-Yang Tongjian envoy and appointed the mortal Qiao Gaoxing, the former boy of Taibai Jinxing, as the messenger, and ordered him to investigate secretly and find out the traitor. After Diaosi Qiao Gaoxing took office, the first thing he did was to use his position to start business. With a series of coincidences, he also discovered that things seemed not that simple.
