Wei Xiaobao (Jordan Chan), a smart and smooth person, helped the "Anti-Qing and Restoration Ming" organization Tiandihui to repel the Qing army out of loyalty. He then accepted the organization's order to sneak into the palace and become a fake eunuch who had not been castrated, preparing to steal the 42-chapter Sutra that contained the secrets of the Qing Dynasty. After accidentally meeting Emperor Kangxi (Ma Junwei) in disguise, the two became close friends. In the palace, Oboi wanted to usurp the throne and seize power. The evil cult Shenlongjiao put the real empress dowager under house arrest and sent people to pretend to be the empress dowager, also with the purpose of stealing the 42-chapter Sutra. Wei Xiaobao began to deal with everyone with his cleverness and wit, helping his good brother Kangxi while thinking about how to do things for the Tiandihui. But when choosing between righteousness and profit, Wei Xiaobao did not forget to be romantic and happy. Seven women, including Jianning, Shuang'er, Mu Jianping, etc., fell into his arms one after another, and they became jealous and played tricks, which really gave him a headache.
