Episode 17 recap: Qi Yan saved Cui Wan Er and Qi Su.

Li Meng Meng took out her own instant noodles and gave them to Cui Wan Er, Qi Yan, Qi Su, and others. As soon as Cui Wan Er smelled it, she found it very fragrant. She asked Li Meng Meng what it was, and Li Meng Meng said it was her family's specialty instant noodles.Everyone enjoyed the food very much. Qi Yan thought it was even better than what the imperial kitchen made, and Sai Xue didn't expect Li Meng Meng to be such a good cook. When Cui Wan Er saw that the person delivering the medicine was Qi Su, she immediately became nervous. Qi Su said the medicine had been brought and asked if it was time to pay.

Pirate Ma Kun immediately ordered his men to tie up Qi Su. He told his men to inform the pharmacy owner that Qi Su would be staying here for a few days. After Lord Sai's death, Qi Yan planned to return to the capital to continue his investigation. Li Meng Meng asked him what would happen to Sai Xue. Just as they were discussing it, Sai Xue came in and said she had dismissed all the servants of the Sai mansion.

Sai Xue said she was leaving, and Li Meng Meng asked her where she was going, but Sai Xue didn't know. Qi Yan suggested that if Sai Xue didn't mind, she could manage this mansion and the Sai family's escort bureau. Sai Xue was very grateful to him.

Qi Su mixed some Ma Fei San (a type of medicine) in the herbs that were delivered. Cui Wan Er saw that Ma Kun was sleeping very soundly. She quickly untied Qi Su, and they were about to escape when Ma Kun woke up. It turned out that he had seen through Qi Su's plan. After years of fighting and struggling outside, Ma Fei San was no longer effective on him.

Sai Xue said that after her father's death, several orders had been canceled, and now she was planning to sell off some things. Lu Huan, Li Meng Meng, and Qi Yan didn't understand why Sai Xue took some window paper, and they couldn't understand why it would be valuable.

Sai Xue told them that it wasn't ordinary window paper; it was sent by Lady Qian and was very valuable. Qi Yan thought about how Lord Qian was usually so frugal, but his wife was extravagant. Qi Yan figured something out and told Lu Huan to quickly ask Lord Qian to send the disaster relief grain. They realized why the officials had arrived at the yamen so promptly a few days ago—it was all because of Lord Qian.

Li Tao and the others returned to Yangcheng. He planned to get back the money he had spent on buying grain initially. Qi Yan came to inspect the disaster relief grain that Lord Qian had prepared, but there was only a layer of rice on top, and the rest was all boards.

Lord Qian immediately realized that the situation had been exposed and quickly knelt down, claiming he didn't know what was going on. Just as Qi Yan ordered to capture Lord Qian, someone shot an arrow from the shadows. Lord Qian quickly signaled with a flare, and Li Meng Meng felt that Qi Yan was in danger. Lu Huan told her that going would only cause more trouble. During the fight between Sai Xue and Lord Qian, they almost lost their lives, but fortunately, Li Tao arrived in time to save her.

Li Meng Meng quickly asked if Qi Yan was okay, and he reassured her that he was fine. Li Tao interjected, saying that if he hadn't arrived in time, would they be standing here safely? Qi Yan asked Li Tao why he had escaped initially and now returned to throw himself into the trap.

Li Tao explained that their country had been experiencing a long period of drought, and he had run out of money. Now all he had left was a steamed bun to eat. Li Tao asked Qi Yan to tell him the secret of water diversion, but Qi Yan sarcastically replied that he wouldn't tell him, as he believed Li Tao would figure it out on his own.

Kong An found it strange that Cui An Shi was transporting cotton clothes on such a hot day. Qi Yan suspected that they were probably not transporting cotton clothes and instructed Kong An to investigate. Li Meng Meng and Lu Huan helped a wounded person inside, and Qi Yan recognized the person as Zhui Ying.

He quickly asked what had happened, and Zhui Ying informed him that Cui Wan Er had been kidnapped by Ma Kun in the palace, and Qi Su was trapped inside. Qi Yan and the others discussed how to rescue the two. Li Meng Meng came up with an idea and took out a bubble-making machine from her bag, thinking it might be useful.

Li Meng Meng explained that she knew M Medicine was ineffective against powerful individuals, so she had added a poison to it. The group arrived at the location where Cui Wan Er and Qi Su were being held captive and coincidentally encountered the people sent by Cui An Shi to kill them.

Li Meng Meng used her bubble machine to kill them, and Qi Yan instructed everyone to leave the area first. Qi Yan and Qi Su learned that Cui An Shi had dispatched people to pursue and kill them, so they discussed how to deal with Cui An Shi.

Meanwhile, Cui An Shi also learned that Qi Yan had discovered the disaster relief grain and was figuring out how to deal with Qi Yan.
