In order to protect the country, Zhao Bang, the founding emperor of Dayong, pretended to demote his concubine Zhao Heng as King Dai, but actually entrusted the orphans Cheng Ping and Zhou Bo to succeed Li after the chaos in the government. Zhao Heng met the Bai Yueguang Li family in Dai and raised four sons. However, Zhou Bo destroyed the family for the "Qing Li Party". After he ascended the throne, Zhao Heng met Zhou Boy's righteous daughter, Bai Di sword slave Wei Ying, and abused her in every possible way because he suspected that she was a chess piece. Wei Ying was newly widowed after being forcibly taken over. Because of the red mole behind her ear, she was protected by the Empress Dowager Fu and entered the palace. She secretly helped Zhao Heng govern the country and quell the rebellion with her intelligence. The two fell in love with each other in life and death, but due to the disparity in status, they could only stay together in secret. Empress Xiao set up a scheme to cause Wei Ying to have a miscarriage, and she made a blood oath with hatred to "live or die until we meet again" and died. Eighteen years later, Zhao Heng died suddenly of vomiting blood and was buried beside Muzhong Weiying's tomb. She only asked Huang Quan to listen to her sleep.
