After Zhen Xuan returned to the palace, Zhungeer Khan entered the palace to propose to the emperor and asked to marry Xi Guifei (Zhen Xuan). Zhungeer Khan mentioned in a private conversation with Zhen Xuan that Zhen Xuan was having an affair with Guo Ziyu County and was heard by the emperor's AnShao. So the emperor pretended to ask Zhen Xuan to marry Zhungeer and kiss him. Wang Guojun believed it, so he rushed out of the city with his guardian, trying to save Zhen Xuan. So the emperor confirmed that Guo Ziyu County had feelings for Zhen Xuan. The emperor asked Guo Jun Wang to guard Yanmenguan for three years and then recalled it. On the night of the recall, the emperor forced Zhen Xuan to poison King Guo Xian with poisoned wine. Zhen Xuan couldn't bear the death of Guo Ziyu County, so he drank poisoned wine for himself and was found by Guo Ziyu County, so he stole their wine. Guo Ziyu County died in Zhen Xuan's arms. Zhen Xuan was heartbroken and fell off the stage of fairy tales and hurt his leg. He can't dance anymore, and he doesn't have to dance anymore.
Zhen Xuan hated the emperor so much that he poisoned him with Ning Guiren. He supported the May 4th movement and became the Queen Mother himself.
