On the night when Jiang Yan died on behalf of his best friend Su Li, the ghost king Ye Xuanming knelt by the River Styx, with blood and tears streaming down his face, begging her to come back. But she was no longer the one in his memory. A hundred years later, she was reborn as a remnant soul and was caught in the vortex of conspiracy between the Yin and Yang worlds. Su Li's soul is disintegrating, Bai Wuchang's chain hides the Old Testament, and every piece of soul thread collected by the psychic Shen Huai is a countdown to her rebirth. As for Hong Gu's Forgotten Soul Soup, drinking it all in one gulp will completely forget him - including him and himself.
