Chen Wende's subordinates intercepted the Yaozhou secret letter, and Chen Wende learned of the plan of the governor of Yaozhou, and planned to lead troops to occupy Qingzhou. Wan's mother invites an artist to paint portraits of the newlyweds, but because only Feng Yao is there, the artist has to paint for Feng Yao alone. Feng Yao is embarrassed to paint alone, and invites Moxi to paint together.
Chen Wende sent out the siege signal, and the people fled one after another. Wan Jiagui knew that this move was a strategic strategy, and the fleeing of the people would seriously affect the defenders of Qingzhou City. Wan Jiagui saw the people fleeing in a panic on the street, and was going to the state capital to discuss the matter, and asked Xiao Jiang to return to Wanfu to inform his parents not to go out easily in the next few days. Wan Jiagui also transferred the dagger on his body to Moxi for self-defense, and told Moxi not to be brave even if she had a dagger in her hand, and to learn to show weakness when she should show weakness.
After the artist finished the portraits of the two sisters, Feng Yao noticed that Mo Xi was frowning and her expression was ugly. Because of Wan Jiagui's marriage to Fengyao, Moxi feels frustrated, thinking that no matter how hard she tries, she can't change her fate.
Xiaojiang returned to Wan Mansion to convey Wan Jiagui's instructions. Fengyao learned that Qingzhou City is not stable now, and Wan Jiagui will not return to the mansion. She came to Moxi and wanted her sisters to rest together, but Moxi naturally would not reject. Chen Wende led officers and soldiers to attack the city in the middle of the night. The next day, Wan Jiagui sent Xiaojiang to send a message back to his home that Qingzhou City was difficult to defend, and asked his family to leave the city as soon as possible. Wanfu Wanmu and Fengyao sisters set off in two routes, and then they met outside the city and went to Luozhou together.
Xiaojiang escorted Fengyao Moxi out of the city with officers and soldiers. Fengyao hoped that no matter what happened, the two sisters would not be separated. Wu Yin found the figures of the two subordinates sent to protect Moxi, knowing that they disobeyed his orders, but obeyed the order of the prime minister to protect him. He was very angry and wanted to look for Moxi, but he was beaten unconscious by his subordinates secretly and taken away.
Beishuo Army appeared to stop Fengyao Moxi's carriage and shot Xiaojiang. Beishuo Army learned that the two sisters were Wan Jiagui's family members and ordered them to be taken away. Although Chen Wende captured the city of Qingzhou with the Crow rocket, he was unwilling to use this weapon to harm the people and officers and soldiers of Qingzhou. He only wanted to occupy Qingzhou and mine underground iron ore. Wan Jiagui also did not expect that Chen Wende did not initiate a frontal conflict with the city defenders, but instead sneaked into the city and launched a surprise attack. Wan Jiagui wanted to take the remaining Longxiang army to break out of the city.
Moxi and Fengyao were taken into Wanjia and imprisoned. Chen Wende came to Wanjia to visit Moxi. When Moxi met, he accused Chen Wende of causing war and asked him why he did not negotiate peace with the court and state his grievances. However, Chen Wende said that both Zhong Yuqi and Wu Lang sentenced him to early death, and he was afraid that he would die before stating his grievances. Fengyao didn't know until this time that Mr. Wen of Qingzhou Women's School was the traitor Chen Wende, but she was not afraid of Chen Wende. Chen Wende wanted to change Moxi to a comfortable room, and Moxi wanted to stay with Fengyao, but Fengyao didn't want to accept Chen Wende's favor, so Moxi had no choice but to stay in the firewood room with Fengyao.
Xiao Jiang fled while he was on the defensive. Chen Wende was very angry when he learned about it, and ordered his subordinates to capture him and Wan Jiagui alive. In order to force Wan Jiagui out of hiding in the city, Chen Wende planned to cut them off from water and food. Soon Wan Jiagui also discovered Chen Wende's scheme, the Longxiang army suffered heavy casualties, Wan Jiagui planned to find the right opportunity to break out of the city as soon as possible.
Moxi was suffering from the cold in the firewood room, she persuaded Fengyao to go out together, but Fengyao insisted on rejecting Chen Wende's favor. Knowledge, as well as a husband, but she is just an illegitimate daughter from a humble background, not qualified to be the official wife of a court general. Feng Yao wanted to explain, but her body couldn't hold on and she fainted. Moxi noticed that Fengyao was hot all over and had a fever, and threatened the guards to notify Chen Wende as soon as possible. The governor of Yaozhou ordered someone to show his favor, but Chen Wende already knew the other party's mind through the previous secret letter, expressing that he wanted to show sincerity in order to form an alliance, and he hoped to get the secret volume of forging iron in the other party's hands.
Knowing that the well in the city had been poisoned, Chen Wende hurriedly took people to check it out, but Chen Wende ignored the news that Moxi sent people to send it. Fengyao knew that it would be difficult to come to the rescue with Wan Jiagui's troops, so she told Moxi that if she couldn't persist, she would ask Moxi to cremate herself and bring her back to Jingzhou, and she told Moxi to live well.
