Xia Chen was originally the "wasted body" of the Xia family. After a breakthrough in sword training, he was qualified to join the arsenal. He unexpectedly awakened his double pupils and system, and learned the "Taichu Emperor's Way to Control the Heaven". He was forced to marry Princess Yaoguang, the future empress, and was involved in the theft of military defense maps. He showed his strength in capturing thieves in the Yulin Guard, but was feared by the royal family. He later served as the director of the Ninth Division of the Lampbearer, cleaning up the backlog of the Supervisory Council, and recruiting talents such as Xu Xingchen to build his power. After the death of the emperor, Xia Chen exposed the conspiracy of the three princes to seize the throne and helped Yao Guang ascend the throne, but refused to kneel down and confessed that he had controlled the power of Dafeng and Daqing. Finally, he agreed with Yao Guang to start the era of spiritual recovery and start a new journey together.
