Description：Bao Gong (played by Jin Chaoqun) was ordered to thoroughly investigate the whole story of the Cai River bursting. Du Ping, the water conservancy supervisor, revealed to Bao Gong that the prince and minister Yu Cai privately built pavilions by the river, which led to the tragedy. However, the extremely astute Gongsun Ce found suspicious points in it. The shoddy work of the dam project was the primary reason for the bursting of the Cai River, and Du Ping's uncle Luo Qiong was involved. Princess Anxiang from Japan came to the Song Dynasty to marry and was named Hefei. Renzong was greedy for Hefei's beauty, and for a time, she became a celebrity in the harem. Hefei had a miscarriage, and Pang Fei, who had a close relationship with Hefei on weekdays, became the biggest suspect. Under Bao Gong's fiery eyes, some conspiracies had nowhere to hide. It turned out that the purpose of Hefei's trip was to help the Japanese Fujiwara family usurp the Song Dynasty, and the Eighth Prince (played by Long Long) was worried because he was not chosen as the heir to the throne.
