On the day of my death, the sky collapsed and the earth collapsed. I took my last breath among the rubble, but instead of waiting for the seducer who came to the underworld, I met Po Meng carrying a soup pot. "Your yang life has expired, but you are bound by 'unresolved causes'." She scooped up a spoonful of white mist soup, but did not pass it to my mouth. "If you help Ying Si stabilize the balance of yin and yang, I will give you a chance to start over."
In this way, I embarked on the road to renewal of my life in a daze, and for the first time I met the Yingsi whom Po Meng said - he is the Mr. Yin and Yang praised by everyone in the world of the world. He can drive away the evil spirits with a wave of his hand. He is also the special "Yinshi" in the ghost judge's palace in the underworld. Once the judge's order comes, he will arrest the souls of the dead without any complaints.
Behind the scenery, there is murderous intention everywhere: the evil spirits in the world seem to be deliberately targeting him, and the judges in the underworld look at him with increasingly cold eyes. Even I, the "life-extender", have been in danger of life and death many times. When dawn can no longer dispel the haze of the two worlds, and when Yingsi is forced into a desperate situation by the rules of the Yin and Yang worlds, how can we find a way out for ourselves in this chess game full of traps?
