A strange car accident threw Fan Shi, who returned home, into the gray area of life and death - the spiritual system was coldly bound, and "soul attractor" became his new identity. The lead-gray sky, the gray-black fog, and the subtle crying all woven together into a blurred space that was neither life nor death. The frantic mother holding her dead baby girl in the reeds, and the chain mark emerging from her palm, bring the mission and humanity to the forefront. The story unfolds in the interweaving of a rough sense of reality and a gloomy atmosphere of the netherworld. In the past, I was running for life, and today I am guiding the souls of the dead. A unique journey of seeking survival and answers in the gap between yin and yang begins here.
