Episode 18 recap: Zhou Shi Yu implemented commercial policies.

Zhou Shi Yu told Yue Ling that the Supervisorate of the Imperial Household only had power over the Prefecture of Jingzhao, and the West Market was under its jurisdiction, which would surely allow the people of Dongyu to live good lives. Yue Ling was secretly pleased to know about Zhou Shi Yu's recent situation, and when Zhou Shi Yu gave her money, Yue Ling refused it, making Zhou Shi Yu realize that Yue Ling had not taken money from the King of the South, but had borrowed it.

The lip rouge from the paintings of the Perfect Gentleman of Beisuor became a trend in the north, with noble ladies proudly displaying their possession of a box. Yue Ling also made a lot of money from the popularity of the lip rouge and saved many Dongyu women. After learning about this, Zhou Shi Yu decided to go to the West Market to join in the excitement. At the West Market, Yue Ling led Xing Yi and others in selling the lip rouge, and Su Nian and others also came to support them. The noble ladies rushed to the scene to buy the lip rouge, and in the scuffle, one of them accidentally pushed the Queen Consort, causing her to fall and hit her head on the table, fainting. Zhou Shi Yu happened to witness this and immediately carried Yue Ling away, ordering the guards to detain all the noble ladies.

The princes and ministers found the Emperor because their daughters had been imprisoned, and the Emperor then summoned the King of the North and the ministers to the court to discuss the matter. The King of the North ordered all the noble ladies to apologize to the Queen Consort, and threatened that if she did not regain consciousness, the noble ladies would pay with their lives.

The Prince of Gaoshan spoke softly to the King of the North, who then took the opportunity to propose a deal. With the implementation of the commercial policy in the West Market imminent, the Prince of Gaoshan must have a solution, so the Prince, along with other princes and ministers, went to persuade Chancellor Zhou Jing Yuan.

In the West Market, Zhou Shi Yu announced that the people of Dongyu could freely engage in commerce, with the same treatment as the people of Beisuor, and they no longer needed to hide.

The people of Dongyu were very happy to hear this and cheered for the implementation of the policy. Yue Ling pretended to be ill at the palace, and when Xing Yi learned that the commercial policy had been implemented, he immediately reported it to Yue Ling, who was also delighted. Xing Yi helped Yue Ling respond to the invitations from the people of Dongyu and decided to bring Su Nian along.

Yue Ling asked Qian Qian to notify the Perfect Gentleman, and she herself notified the King of the North. Yue Ling made tea cakes and gave them to Zhou Shi Yu, who was disappointed because he felt that even he had been manipulated by her. If he had not arrived in time, perhaps Yue Ling would not have been able to resolve the situation. Yue Ling also realized her mistake and held onto Zhou Shi Yu's clothes, not letting him leave.

Zhou Shi Yu hoped that Yue Ling would tell him immediately if she encountered any problems in the future, so they could solve them together. Yue Ling and Zhou Shi Yu went to the West Market, singing and dancing, and the people of Dongyu recognized Yue Ling. Zhou Shi Yu immediately explained that he had mistaken her for A Shi Na Zhu, the Princess Dowager, and Yang Xu, who overheard their conversation, was filled with confusion.

In the West Market, Yue Ling led Xing Yi and others to sell lip balm. Su Nian and others also came to support them. The noble ladies arrived at the scene to purchase the lip balm, and they even fought on the street to get a box of lip balm. Yue Ling was surprised to find that Gao Luo Yi was also there. Gao Luo Yi was also very surprised to see Yue Ling.

The noble ladies accidentally pushed the Queen Consort, causing her to hit her head on the table corner and faint. Zhou Shi Yu witnessed this and immediately took Yue Ling away, ordering the guards to detain all the noble ladies. The princes and ministers went to the Emperor because of their daughters' imprisonment. The Emperor then discussed the matter with the Northern Prince, and the Northern Prince asked all the noble ladies to apologize to the Queen Consort, threatening to execute them if the Queen Consort remained unconscious.

The Prince of Gaoshan spoke softly to the Northern Prince, who then seized the opportunity to propose a deal. Knowing that the West Market commercial policy was about to be implemented, the Prince of Gaoshan was eager to help, so he brought the other princes and ministers to persuade the Prime Minister Zhou Jing Yuan. Zhou Shi Yu then announced that the people of Dongyu could engage in free trade, with the same treatment as the people of Beisuо. The people of Dongyu were overjoyed at the policy implementation.

Yue Ling pretended to be ill in the palace. Xing Yi learned that the commercial policy had been implemented and reported it to Yue Ling, who was also delighted. Xing Yi helped Yue Ling accept the invitation from the people of Dongyu and decided to bring Su Nian along.

Yue Ling asked Qian Qian to notify the Young Master of the Ten Perfections and informed the Northern Prince herself. Yue Ling made tea cakes and sent them to Zhou Shi Yu, who felt dejected because he had also been plotted against. If he had not arrived in time, perhaps Yue Ling would not have been able to resolve the situation. Yue Ling realized her mistake and held onto Zhou Shi Yu's clothes to prevent him from leaving.

Zhou Shi Yu hoped that Yue Ling would tell him immediately if she encountered any problems in the future, so they could solve them together. Yue Ling and Zhou Shi Yu went to the West Market to sing and dance. The people of Dongyu recognized Yue Ling, and Zhou Shi Yu immediately explained that he had mistaken her for Princess A Shi Na Zhu. Yang Xu was puzzled by their conversation.

The Prime Minister instructed Su Nian to report on the situation of Zhou Shi Yu and Yue Ling. As Su Nian had not found their weaknesses, the Prime Minister told him to continue infiltrating and stealing the jade pendant, and assassinate them. After Su Nian left, the Prime Minister suspected that he had changed his mind and ordered his subordinates to stop Su Nian's medication, as he was no longer useful.

Xing Yi wanted to keep the good things for Su Nian. Yue Ling learned that the people from the Northern Prince's residence had brought her the gifts bestowed by the Emperor, further increasing her fondness for the Northern Prince.

Zhou Shi Yu took Yue Ling to see the lights of a myriad of households. Suddenly, fireworks lit up the sky, and Yue Ling immediately prayed, as did Zhou Shi Yu, who hoped that Yue Ling could become his Queen Consort.

The Northern Prince implemented the commercial policy, increasing tax revenue, for which the Emperor rewarded him. Prime Minister Zhou Jing Yuan reported that Yue Ling had impersonated a princess. At the same time, Yue Ling was inspecting the style of her wedding gown in the residence when the imperial guards rushed in to arrest her.
