It's the year 1722 AD. The fourth son of the king, Prince Yin-Zhen, accedes to the throne and names his ruling dynasty "Yong-Zheng". Shortly afterwards, the new Emperor's Consort Hua, Nian Shi-Nan, becomes extremely aggressive in the Imperial Harem.
The Emperor sentences Concubine Yu Ying-Er, who tried to poison Zhen Huan's medicine, to commit suicide. Concubine Yu refuses to adhere to the sentence.
Concubine Ye Lan-Yi leads Moz-Yan, a nun in Gan-Lu Temple to the palace to testify to Zhen Huan's innocence. Lady Qi ultimately fails Zhen Huan. However, Wen Shi-Chu has to castrate himself because of An Ling-Rong's threat.
Zhen Huan is pregnant again, but she knows her body is too weak to give birth. She plans a way to miscarry, and blame it on the Empress, in order to have the Empress imprisoned.
