Lian Huan couldn't buy embroidery thread, so Huang Beishang guessed that it was Zhenqu Youjia who did it. Just when they were anxious about not having embroidery thread, Huang Beishang learned from a book that the roots of the Jie Ma tree could be used to make thread, and asked Lian Huan and Ye Pei to work with him overnight to peel the roots and pull them out with bare hands. Ye Pei complained that this method was too difficult, and he didn't know how to polish it into a thin line. Huo Qingyun watched silently from a distance. After Huang Beishang fell asleep, he peeled off all the tree roots and drew silk from his memory to make embroidery thread and placed it in front of Huang Beishang's window.
After Huang Beishuang woke up, she knew Huo Qingyun had come when she saw the embroidery thread. She walked out with a candle, but Huo Qingyun deliberately ran into the room to avoid her. Huang Beishang knew that he was behind her, so she pretended to fall and let Huo Qingyun support her. The two were flirting, Huo Qingyun said that she missed him, Huang Beishang was duplicitous, and asked him why he came here, Huo Qingyun only said that he was doing old things for old friends. Ye Pei heard voices in the room, and Huang Beishang helped Huo Qingyun cover it up, saying that he had fallen asleep.
The next day, Huo Qingyun took advantage of the darkness to come to Yunfang Pavilion again. Huang Beishang put her arms around his waist to make him fall in love. Huo Qingyun felt sorry for Huang Beishang's injured hand and accompanied her to finish the embroidery. Master Zhu highly praised Zhen Qu Youjia's embroidery, and Na Zhan thought it was valuable for collecting. However, he saw that Huang Beishang's embroidery was a wrist guard and complained that she did it perfunctorily. Huang Beishang knew that Zhan would think so and asked to explain the situation of the embroidery in person. She asked General Wu to slash the wrist guard with a knife. Na Zhan was surprised that the wrist guard was not damaged and asked how it was made. Huang Beishuang said that he had just finished reading the chapter on herbal medicine and found that the roots of the Jiema tree could withstand the blade, so he had a sudden idea to complete this embroidery. Nazhan was very satisfied with the wristband, but he felt that it was impossible to judge the outcome of the two. Master Zhu suggested that the two ladies should present delicacies ten days later before making a judgment, and Nazhan agreed.
Zhen Qu Youjia was not happy and accused Xiao Lian of having a bad idea. Although she took Huang Beishang's embroidery thread, she still let her use tree roots to take advantage of the loophole. She believed that the next time the delicacy should not be taken lightly. If Ruowen waited for Qin Duo at the door of the Ordnance Department, Manhu was doubtful about the news. The brother received the news from Mang Liu and found out that Ge Xinwei was in the brothel. If Ruo Wen found out, he was ready to kill two birds with one stone.
The madam had nothing to do with Ge Xinwei. Ge Xinwei had a bad temper and refused to accept guests for dinner. If Ruowen and others barbarically broke into the brothel and pretended to have fun, the madam decided to use Ge Xinwei to serve her. Ge Xinwei saw Ruowen coming, questioned him for coming too late, and complained that she was forced to pick up guests. Ruo Wen gave her a chance to relieve her anger, and Liu Li Liu Qi asked Ge Xinwei to repay her. Manhu threatened the madam and asked him to use the brothel venue to get the madam and others to cooperate.
Shaqu used Ge Xinwei's portrait to visit the Ernaqi tribe and found out that she was the leader of Naxi. After Huo Qingyun learned about it, he determined that Huang Beishuang and Ge Xinwei had exchanged identities and got married. He remembered that Madam Ma Sui asked for help outside the door before, and blamed himself for killing Madam Ma Sui. Shaqu believes that the revenge of killing his mother is difficult to solve, and knows that the marriage between Huo Qingyun and Huang Beishang cannot continue.
Huang Beishang thought about the principle of the double fruit tree and guessed that the second part of the strange volume was about climate. She was immersed in the book, and it was late at night before she knew it. She walked out of the room and looked across, but she didn't see Huo Qingyun.
Qin Duo came to Zuixianglou to have fun, and Ruowen dressed up as a servant to greet him, and deliberately arranged for Ge Xinwei to pick up the guests. Ge Xinwei planned to take the opportunity to steal his key but was discovered instead. Qin Duo forcibly used force on Ge Xinwei. Ruowen couldn't help but broke into the room and pushed Qin Duo away, beating him up. Afterwards, Ruowen accused Ge Xinwei of being brave, but Ge Xinwei was frightened by the scene just now.
Huo Qingyun took advantage of Huang Beishuang's sleep to see her. Unexpectedly, Huang Beishang deliberately pretended to be asleep and waited for him, asking him if something had happened to him. Huo Qingyun knew that he could not face Huang Beishang, so he wanted to leave with some excuse. Huang Beishang gave him a belt made from the roots of the Jie Ma tree. Huo Qingyun accepted it after hesitation, but Huang Beishang thought his behavior was strange.
