At the end of the Chu Dynasty, the three major families controlled the government, and their spiritual veins dried up, causing the monks to become mortals. The protagonist Zhang Tao traveled through time and became a eunuch in the cold palace, activated the "Destiny System", and discovered the "Seven Deadly Sins Blood Pact" in which the royal family used blood sacrifices to suppress the ancient demon. Each generation of emperors must collect seven sin seals such as arrogance and jealousy, otherwise the demon will come to the world. The system requires him to complete the reversal of the blood contract within seven days, otherwise he will be punished by heaven. At this time, the rebels outside the palace raised the banner of "Qingjun Side", and the eunuch Liu Zhongxian, the chief of etiquette in the palace, raised the dead soldiers in an attempt to support the puppet emperor. A game concerning the survival of the dynasty unfolded in the blood mist.
