Shen Yurong approved Xue Fangfei's name card, but assigned her to the music department, and Jiang Jingrui stood up for her. Xue Fangfei guessed that Shen Yurong had something to do, and learned that he was mainly responsible for compiling classics, and wanted to see him and Wan Ning reveal their flaws first. Xue Fangfei joined the music department, but her opportunity to perform as a solo was taken by Mr. Xiao. Mr. Xiao deliberately mocked her for being arrogant and asked her to only assist in playing. During the rehearsal process, Mr. Xiao tricked her into not being able to keep up with the rhythm of the music score, so Xue Fangfei took the initiative to stay alone to practice.
Wenji stumbled with his mouth full of purple. He finally found Situ Jiuyue, but was bitten by a poisonous snake. Xiao Heng asked her to stay in the Duke's Mansion temporarily to keep her safe while she waited for Prince Jokhang to come to Yan. Situ Jiuyue was very happy, but Xiao Heng asked her to help save the two of them. Situ Jiuyue guessed that Xiao Heng was interceding for Xue Fangfei and asked her to accompany him to catch spiders and deliberately create the illusion of falling into the water, hoping to test Xiao Heng's intentions.
Shen Yurong presided over the alliance affairs. Xue Fangfei was exhausted from rehearsing day and night. Mr. Xiao was worried that she would affect the musicians' rehearsal, so he informed Shen Yurong of the matter. Shen Yurong asked her to stop rehearsing and rest first. After Ye Shijie learned about it, he sent medicine to Xue Fangfei. Xue Fangfei hoped that he would help her speak in front of the Holy Emperor and planned to develop innovative new performance forms.
Emperor Hong Xiao supported Xue Fangfei's idea, but Shen Yurong had nothing to say. Xue Fangfei went to the Hanlin Academy to look for Shen Yurong, and happened to meet Zhao Qi, who teased her about her relationship with Shen Yurong. Shen Yurong arranged for her to co-star with Zhao Qi, but Xue Fangfei did not refuse. She asked Xueer to take out the brocade handkerchief and wanted to negotiate a deal with Zhao Qi.
Zhao Qi originally wanted to watch Xue Fangfei's show, but he didn't expect to get involved. Xue Fangfei used Yunjin's handkerchief to lure him and asked him to take the initiative to tell Shen Yurong that he didn't want to co-star. Zhao Qi pretended to be reluctant to cooperate with her. Shen Yurong reprimanded him that he should focus on the Jozhao mission and not have personal emotions. When Zhao Qi failed to resign, Xue Fangfei tricked her into cooperating with him in acting, deliberately making Shen Yurong feel that the relationship between the two was special and they could not co-star due to a previous blind date.
Shen Ruyun came to find Shen Yurong, and the two happened to hear Xue Fangfei and Zhao Qi quarreling. Seeing Zhao Qi leaving angrily, Shen Yurong asked Xue Fangfei why. Xue Fangfei thought that Shen Yurong was deliberately making things difficult for her. She said she would not give up, and Shen Yurong had to say that she would find a co-star for her.
The next day, Mr. Du came to the Hanlin Academy to report. He happened to meet Zhao Qi and asked him why he didn't accept this good thing. Zhao Qi deliberately said that Xue Fangfei was not and that scaring Mr. Du was not as good as imagined. Mr. Du believed it and pretended to have diarrhea and was unable to rehearse. Unexpectedly, Zhao Qi had been bribed by Xue Fangfei and promised to give him a string of beads.
There was a thunderstorm and Xue Fangfei was late for rehearsal. When she learned that Mr. Du was not here, she pretended not to know. Shen Yurong comforted her and asked her to wait until the rain stopped before leaving. Xue Fangfei saw the fragments and remembered the past, and learned that Shen Yurong wanted to compile this into a classic. The two talked for a long time, and Xue Fangfei probed Shen Yurong's state of mind. Although the two did not say it explicitly, they each knew it well.
Xue Fangfei couldn't help but feel sick when she left the Hanlin Academy. Xiao Heng saw her wearing Shen Yurong's clothes and took her back to the Duke's Mansion. The two teased each other about being single, and Xiao Heng reminded her that it was dangerous to get close to Shen Yurong. Xue Fangfei is confident. She wants to find a handle on Shen Yurong, and she doesn't want to back down even when facing Wan Ning. Xiao Heng hoped that she would not include him in the scheme, saying that he could not afford the loss.
Shen Yurong went home and was questioned by Shen's mother. Mother Shen reminded him that the life he had now was not easy, and he should not offend Wan Ning or be with Xue Fangfei. Shen Yurong said that she knew what she should do and asked Shen's mother not to interfere.
Situ was drunk in Jiujiu, so Xiao Heng planned to lock her up in the Duke's Mansion until the Jokhang delegation came to Yan. Xiao Heng asked Wen Ji to stay while he and Lu Ji went out to do business. Chu Lan and others have been following this for a long time, looking for an opportunity to attack Situ Jiuyue. After Situ woke up in September, he shouted that he was going to treat Xue Huaiyuan. Wen Ji was worried about being beaten by a military stick, so he accompanied her to Ye's house.
Ye Shijie heard that they were Xiao Heng's people and refused to let them in. Situ Jiuyue threw out the poisonous spider, and Ye Shijie was instantly poisoned at the corner of his mouth. He had to watch Situ Jiuyue prepare the poison for Xue Huaiyuan. Situ sent Wen Ji away in September and prepared to run away quietly, but was ambushed by Chu Lan. She and Wenji were no match for Chu Lan, and they were seriously injured. Wen Ji detoxified Ye Shijie and asked him to find Xiao Heng. Situ Jiuyue had no choice but to take a gamble and throw the gas bomb, and all three of them fainted.
