Bai Jing, the goddess of the Chemistry Department of Yenching University, suffered facial disfigurement due to a chemical experiment (actually an accident deliberately caused by her assistant's jealousy of her talent), which led to her boyfriend abandoning her and her classmates despising her. In the end, he couldn't bear the changes in the world and chose to commit suicide. However, his soul passed over to Pan Jinlian. He was immune to handsome men (Siemens, Hua Zixu), etc. He knew his own advantages. Through the knowledge of chemistry he learned, he changed his destiny and became rich in the Song Dynasty.
