Yandere male protagonist: Ye Wuyang, formerly known as "Xie Jingzhao", is the only son of Xie Mingxiu, the former Minister of Household Affairs. When he was twelve years old, his whole family was exterminated due to the "Black Lotus Rebellion", and his mother took him to Hanjiang Pavilion. Three years later, his mother was poisoned by the Dou family. Before her death, she left behind a jade pendant engraved with "Jiaolong" hidden patterns (actually a fragment of the former prince's military mobilization talisman). On the surface, she is weak and afraid of colds (she needs to take "Jingxin Powder" prepared by Su Qinghe every day, which is actually a chronic poison inhibitor), but in fact she is proficient in "Sun Tzu's Art of War" and "Guiguzi", good at using poison and psychological manipulation, and has a pure love for Su Qinghe (because she looks similar to her late mother). Twelve years ago, the "Black Lotus Rebellion" was actually forged by the Dou family's relatives and Beishuo in order to eliminate the Xie family members who supported the former prince. Ye Wuyang needs to collect three pieces of the military mobilization talisman to overthrow the Dou family, rehabilitate the family, and reveal the truth about Jinshang's unfair access to the throne (Jinshang is the younger brother of the former crown prince and ascended the throne through a coup).
