In order to save her seriously ill younger brother, the heroine Shen Qingluan was forced to marry into the general's palace instead of her step-sister, to celebrate the death of the general's only son Xie Changyuan, who was rumored to be terminally ill. On their wedding night, she discovered that the groom was already a cold corpse, and the wedding itself was a sinister sacrifice to suppress the centuries-old evil spirits in the General's Mansion. In extreme fear and despair, Shen Qingluan accidentally activated the [Negative Emotion System]. As long as he absorbs negative emotions such as resentment, hatred, anger, fear, etc., He can exchange various Xuanmen spells and magic weapons.
In the general's mansion, evil servants deceived the master, and even fierce ghosts threatened his life. Shen Qingluan used the system to work step by step in the crisis-ridden back house, saving vengeful spirits to collect grievances while slapping living people with ulterior motives in the face, and his strength grew rapidly.
At this time, Xie Xuan, the commander of the "Suppressing Demon Division" of the Royal Secret Service, which specializes in investigating strange events, came to investigate the unusual activities in the General's Mansion. He is cold and powerful, carries a mysterious curse, and is full of doubts about Shen Qingluan, a "strange person" who suddenly appeared. From the initial testing of each other, the two were forced to join forces in strange incidents one after another, and jointly faced a series of supernatural dangers such as living corpses, painted skins, mandrills, and the mysterious case of the City God's Temple.
As the investigation deepens, they discover that the secrets of the General's Mansion go beyond the evil spirits behind it, and involve a huge conspiracy to resurrect the ancient evil god by using all the people as sacrifices. The mystery of Shen Qingluan's life experience, the curse on Xie Xuan, and the safety of the entire dynasty are all closely related to this conspiracy. In the end, Shen Qingluan relied on the power given by the system to grow from a happy bride who was at the mercy of others to a Taoist boss who was respected by the three worlds. Together with Xie Xuan, she defeated the evil god's conspiracy and protected the peace of the world.
