Chen Jiguan, the champion of the Dajing Dynasty, exposed the rebellion conspiracy of the national adviser Fang Jinghe and beheaded the villain. Unexpectedly, Fang Jinghe still had witchcraft, and murdered Chen Jiguan's sister Chen Zhaodi. Chen Jiguan, who has the memory of a modern seventeen-year-old high school student and the memory of Chen Jia Sanlang of the Da Jing Dynasty in the past, was confused by his elder sister's persistence in supporting his younger brother; and his brother-in-law's selfless love moved him. He finally decided that from now on he would only be Chen Jia Sanlang of the Da Jing Dynasty, and secretly vowed to uncover the truth about "losing his elder sister". For this reason, he worked hard and took the road of imperial examination again.
