Hongli insisted on staying in Changchun Palace, Yingluo asked Mingyu to take the emperor to the east hall to rest. On behalf of her maidservant, Hu Po, Er Qing sent Hong Li the hangover soup, and stayed in the east side hall, taking the opportunity to take the throne. The next day, Li Yu was shocked to find that Er Qing had run out from the east hall. Afterwards, Hu Po acted furtively, and Er Qing also left Changchun Palace to go back to Fucha Mansion, Mingyu felt very strange about this. The queen had dystocia and was in a critical situation. Yingluo was worried that the queen would die of dystocia just like her mother, so she was terrified and lost her mind and hid and cried secretly. Fu Heng, who entered the palace after inquiring, found Yingluo and wanted to comfort her, but Yingluo refused without hesitation. The queen gave birth to the seventh elder brother safely, and Hongli loved him very much. Yingluo burst into tears in front of the queen's bed, and was always worried about her comfort. The queen knew Yingluo's heart and was very moved. Hongli named the seventh elder brother Yongcong, implying the meaning of establishing a reserve. Concubine Xian understands Hongli's intentions, and pretends to have no intention of revealing to Concubine Chun Hongli's intention of establishing the crown prince, and claims that princes, ministers and foreign envoys know it well, and send congratulatory gifts one after another. Concubine Chun is very dissatisfied because the sixth elder brother fell out of favor, and jealousy ignites in her heart.
