Shen Yurong asked Shen's mother and Shen Ruyun to pack their bags and go back to their hometown to avoid the limelight, and reminded them not to contact outsiders. Shen's mother was not happy. She was unwilling to return to her hometown in a remote village and thought Shen Yurong dared to leave on her own. Shen Yurong hinted to her that something had happened in the capital, but Shen's mother did not dare to say anything after hearing this.
King Cheng was about to return to the capital to pay homage to his ancestors, and sent a memorial to Emperor Hong Xiao, saying that he wanted to sacrifice the prisoners, so he sent additional troops to escort him. Jiang Yunbai saw the memorial and thought that King Cheng wanted to rebel. He was very angry and suggested to strike first. Xiao Heng thought it was inappropriate. He saw that King Cheng had clear intentions and thought that the matter was reasonable. If the Holy Emperor launched an attack because of this, Emperor Hong Xiao would be able to persecute loyal ministers, and King Cheng's troops stationed outside the city would use this to attack in chaos. He thought this was not a plan that King Cheng could come up with.
Ye Shijie was in charge of the sacrificial ceremony. When he first took office, he was cautious and thought that sacrificial rituals were related to the fate of the country. Fortunately, he received the help of his colleagues. King Cheng's army was already on the way to Beijing, and Shen Yurong went alone late at night. King Cheng praised him for his previous suggestions and thought he was brave and resourceful, and then he understood the reason why Wan Ning fell in love with him. Shen Yurong thought that the only thing left now was the name of a teacher. He had already thought of a plan and offered it to King Cheng. It was up to him to see if King Cheng was willing to do it. King Cheng asked him to speak freely. Shen Yurong wanted to kill Wan Ning and frame the blame on Emperor Hong Xiao, so that King Cheng could send troops smoothly.
After hearing this, King Cheng immediately drew his sword and thought Shen Yurong was impudent. Shen Yurong was calm and unhurried, thinking that King Cheng was not a soft-hearted person, and he had to make sacrifices if he wanted to achieve great things. King Cheng expressed his brother-sister relationship with Wanning. He couldn't bear to trade Wanning's life for the district throne, but he could pretend to be real. Shen Yurong prepared countermeasures. He would not tell Wan Ning about the matter, but would give her a fake death drug. He was worried that Wan Ning would blame her afterwards. He hoped that King Cheng would intercede for him, and King Cheng agreed. Shen Yurong made a condition and wanted Xiao Heng's fish charm.
After King Cheng returned to the capital, Emperor Hong Xiao issued an imperial edict in public, rewarding them for preventing the invasion from the north and protecting Dayan. He deliberately said that he wanted to keep them in the capital after the sacrificial ceremony. King Cheng didn't like these gold and silver jewels at all, and pretended that he would return to the north after the ceremony.
King Cheng came to Wan Ning, and the two siblings met. King Cheng accused her of falling out with Li Zhongnan, knowing that she was confused by the fake pregnancy. The two went to pay homage to their mother, Concubine Liu. They remembered that Concubine Liu was bedridden when she was a child. Before she died, Concubine Liu regretted that she did not have a prominent family background and was not favored by the late emperor. She told the two brothers and sisters of the King Cheng that they would never be together again. Help each other and find ways to fight for imperial power.
Li Zhongnan didn't care about the previous misunderstanding and took the initiative to help King Cheng come up with an attack plan and let their troops divide into four groups. Xiao Heng, Wen Ji and others also made arrangements. Xue Fangfei said that no matter what happened, she would not give up on Xiao Heng.
Jiang Ruoyao sent a letter home, saying that she was living a good life in Yongzhou and hoped that Mrs. Jiang would take good care of her health. Jiang Yunbai remembered the late emperor's instructions before his death and gave him the title of Zhongshu Ling, hoping that he could help Emperor Hong Xiao stabilize the imperial power. In order to prevent the Jiang family from being put in danger, Jiang Yunbai deliberately let go after Emperor Hong Xiao personally handled the government affairs. He felt guilty and blamed himself for what happened to the Jiang family before, expressing his powerlessness. But now that the imperial court is threatened, he should stand up. Mrs. Jiang was happy after hearing this and praised him for finally having the character of the Jiang family.
Yang overheard the conversation between the two and told Jiang Yunxing about it. Jiang Yunxing was worried that he would be blamed if he succeeded as king, so he wanted to pack up his things and run away. Concubine Li was originally sent away by Emperor Hong Xiao, but she was worried about Emperor Hong Xiao's safety, so she insisted on returning and forced her to stay, not wanting to become suspicious of the king. During the sacrificial ceremony, Emperor Hong Xiao wanted to prevent others from taking away the throne, while King Cheng thought about how to seize the throne. Wan Ning remembered that when the late emperor was still alive, she cruelly covered him to death with a pillow because she was dissatisfied with him for sending her to Daiguo as a hostage.
Xue Fangfei arranged for Zhao Ke to make preparations, but Jiang Yunxing colluded with Cheng Wang's people to stun Zhao Ke and kill him. Xue Fangfei received a letter from Xiao Heng and asked Zhao Ke to accompany her there. On the way, Xue Fangfei discovered that this Zhao Ke was fake and wanted to use it to leave. However, she was knocked unconscious by the fake Zhao Ke and sent to Wanning's private prison. Wan Ning wants Xiao Heng and Xue Fangfei to suffer together, and hates them for setting up a fake pregnancy.
