Modern time traveler Shen Wan is the daughter of a traitor and despises her father Shen Zhuo's crimes. However, at the Chinese Valentine's Day Lantern Festival, she meets Pei Jingheng, who came to overthrow Shen Zhuo and stabilize his country. Pei Jingheng deliberately approached Shen Wan in order to collect evidence, but he fell in love with her during the relationship. Because the road to revenge and seizing the throne was full of dangers, in order to protect Shen Wan, he deliberately acted as a cold scumbag and pushed her away. Shen Wan became pregnant out of wedlock and was "abandoned" by her husband, but she saw through his forbearance and disguise, transformed into a gray-scale black lotus, faked death by jumping into a river, and escaped from the shackles of the Shen family. She secretly formed an alliance with the emperor Mu Huai, who was dissatisfied with the weak emperor, and became the hidden line for Pei Jingheng to seize the throne. Pei Jingheng regretted it when he found out that Shen Wan had not died.
