The mistress, Fang Qingkui, was set up by her husband Lu Che and her concubine Jiang Mei in her previous life. In order to save her concubine's daughter, Lu Mingzhu, she jumped into an icy lake. As a result, the cold air entered her body and she was infertile. She eventually died of illness and her dowry was taken away from her. She made a deal with the judge of the underworld and spent a thousand years as a slave in exchange for rebirth. After rebirth, Fang Qingkui returned to the day when the girl fell into the water. She watched with cold eyes and refused to rescue. Seeing Fang Qingkui's carriage go away, Jiang Mei, who was hiding in the dark, watched her daughter Mingzhu drown in the lake. She was also frightened and excited, and the fetus in her belly was not safe. Fang Qingkui's revenge started from the moment she refused to save him. She wanted this pair of bad guys to pay for their debt with blood.
