Which episode of Qi Fei was killed by the emperor?

Qi Fei was killed by the emperor is the ninth episode.

The characters in the TV series "The Queen of the Palace" are based on the historical prototype Li, the concubine of the Qing Dynasty and the female magistrate Li. Yong Zhengdi was a side Fujin when he was Prince Yong, and he was very loved by Yongzheng in his early years. In the early years of Yongzheng, the title of princess was second only to Empress Urnala and Imperial concubine Nian Shi, and higher than the birth mother of Emperor Qianlong. Qi Fei is also an old man in hiding, and has been following the emperor for more than twenty years. When Zhen Xuan entered the palace, he was old. If she hadn't given birth to the emperor's eldest son, the third brother, I'm afraid the emperor would have forgotten her.
