Episode 13 recap: Jiang Xue Ning teaches You Yue a lesson.

Following Jiang Xue Ning's instructions, You Fang Yin went to find salt merchant Ren Weizhi. At this time, Ren Weizhi was penniless and had been kicked out of his room by the landlord. He heard about a new salt harvesting method he had just developed, but no one believed him. Although You Fang Yin offered to invest in him as Jiang Xue Ning had instructed, with the condition that he would take 70% of the profits, Ren Weizhi still agreed. Just after You Fang Yin finished talking with Ren Weizhi, You Yue suddenly appeared in front of her with some people.

Upon learning that You Fang Yin had been taken away by You Yue, Jiang Xue Ning decided to find a way to rescue her. She took her most precious pair of hairpins and gave them to You Yue. After receiving the gift, You Yue felt puzzled and didn't understand why Jiang Xue Ning was being so generous. Through covert investigation, she discovered that Jiang Xue Ning had been doing business with You Fang Yin without her family's knowledge. In order to blackmail Jiang Xue Ning, You Yue had locked up You Fang Yin, intending to use Ren Weizhi to ruin You Fang Yin's reputation. However, Jiang Xue Ning suddenly appeared. Walking up to You Yue, she sneered and remarked how impressive she was. You Yue told her not to meddle, and as they were talking, Jiang Xue Ning suddenly slapped herself. You Yue was bewildered, but upon hearing Jiang Xue Ning being slapped, You Fang Yin rushed over as if she had gone mad and hit You Yue with a chair.

Seeing that the situation was not good, You Yue got scared and hurriedly ran away. Watching their departing figures, Bao Tang couldn't understand Jiang Xue Ning's intentions. Jiang Xue Ning smiled and replied that this time she wanted to teach You Yue a lesson and also awaken You Fang Yin to save herself. In order to achieve this goal, Jiang Xue Ning had already informed Zhou Yinzhi in advance. As per Jiang Xue Ning's instructions, Zhou Yinzhi brought both of them to Xingwuwei. In addition to teaching You Yue a lesson, they also extorted over ten thousand taels of silver from Qingyuanbo. Jiang Xue Ning gave part of the silver to Zhou Yinzhi to take care of the Yan family, and the other part was to be handed over to You Fang Yin. However, Qingyuanbo refused to spend more money to bail out You Fang Yin, so Jiang Xue Ning decided to let You Fang Yin continue staying in prison for the convenience of doing business. She instructed Zhou Yinzhi to take good care of her and allow her to come and go freely.

After arranging everything, Jiang Xue Ning had just walked out of the gates of Xingwuwei when Xie Wei received the news and hurried over. Xie Wei asked Jiang Xue Ning if she realized her mistake, but she told him that she had done nothing wrong. She earned money from the salt merchants only to help the Yan family. It was Xie Wei who didn't tell her anything and caused her to be questioned by the emperor, forcing her to handle the situation. Seeing Xie Wei speechless in response to Jiang Xue Ning's retorts, Jianshu and Lv Xian stood aside, secretly mocking Xie Wei. An evildoer could only be dealt with by another evildoer.

After being confronted by Jiang Xue Ning, Xie Wei decided not to contend with her. The two of them sat down calmly and exchanged information with each other.

When Yan Mu was injured and poisoned by an arrow, Xie Wei suspected that Gong Yicheng was behind it and wanted to use Xue Yuan to get rid of him. The half-sealed letter was definitely the work of Gong Yicheng. However, what puzzled him was why Gong Yicheng only gave Xue Yuan a half-sealed letter. Jiang Xue Ning analyzed the situation for him and felt that Gong Yicheng was waiting for an opportunity.

Based on the assassination attempt on Yan Mu, Jiang Xue Ning suspected that someone had leaked information about Yan Mu's whereabouts. Gong Yicheng knew the news in advance and poisoned the arrow. This indicated that he had infiltrated the Yan family army. In this way, the Yan family was in real danger. Xie Wei told Jiang Xue Ning to go back and focus on her studies, and he would take care of the salt merchants' affairs.

When Jiang Xue Ning returned home, she told Jiang Xuehui about the handkerchief incident. Unexpectedly, Jiang Xuehui already knew about everything. Jiang Xue Ning realized that in her past life, she had been foolishly trying to replace Jiang Xuehui, but Jiang Xuehui was aware of everything and had intentionally indulged her. Jiang Xue Ning had already sent a message to Shen Jie, and Shen Jie came to Baiguo Temple as instructed by her. There, he finally saw the person he had been longing for.

When Jiang Xuehui saw Shen Jie, she pretended not to notice him and began to pray sincerely. Shen Jie followed her and knelt beside her on a cushion, expressing gratitude to the Buddha for granting him an auspicious marriage. Upon hearing this, Jiang Xuehui couldn't help but laugh. Lv Xian followed Xie Wei's instructions and went to the prison to find You Fang Yin. Upon learning that You Fang Yin had initially given Ren Weizhi one thousand taels, she complained that You Fang Yin didn't know how to do business and wanted her to retrieve the money from Ren Weizhi. Hearing that it contradicted what he heard from Jiang Xue Ning, You Fang Yin felt extremely puzzled.

As Jiang Xue Ning passed by an antique shop, she unexpectedly saw Zhang Zhe. She noticed that Zhang Zhe was not only good at solving cases but also skilled in repairing antiques. She approached him and offered to help, intentionally getting close to him. She was pleasantly surprised to find that Zhang Zhe clearly didn't dislike her.
