Episode 17 recap: Pei Xing Jian solved two cases with one move.

Due to Pei Xing Jian's statement, everyone was willing to confess. Lu Li privately approached Wang Jun Meng and asked him if Princess Chang had any involvement in these matters. Wang Jun Meng became nervous and didn't know what to say. Wang Jun Meng couldn't help but admire Lu Li's ability to know so much.

Initially, Wang Jun Meng didn't want to admit it. Lu Li informed him that not only did she know about these matters, but she also knew that the Aijia family had leverage in Princess Chang's hands, which forced Wang Jun Meng to work for them. Wang Chongyu was completely unaware of this. Lu Li also confessed to Wang Jun Meng that they came here under the Emperor's orders. If they were really killed in the Western Region, they would also be implicated. Moreover, the Emperor was afraid of their arrival and wanted them to investigate the Aijia family.

Princess Dachang's desires were merely due to discontent. However, if they knew that Pei Xing Jian was still favored by the Emperor, they wouldn't dare to do such a thing again. Wang Jun Meng was skeptical about Lu Li's words, but he believed that it was better to have uncertain information than none at all. He quickly confessed and stated that Princess Dachang had threatened his family's lives, leaving them no choice. They didn't inform Wang Chongyu about this because they were worried about his impulsive nature and that he would go to the capital to confront Princess Chang.

After learning the situation from Lu Li, Wang Jun Meng was reassured and told not to worry. She would inform the Emperor about everything and ensure their safety. Wang Jun Meng expressed his gratitude to Lu Li and quickly left. After Pei Xing Jian's probing, Zhang Yuanshan confessed to everything, and the cattle thieves were brought to the scene.

The cattle thieves immediately identified Zhang Yuanshan, who was frightened and quickly revealed the truth. He admitted that he only wanted the calf and that the so-called cattle theft was a fabrication. After Zhang Yuanshan confessed, the cattle thieves suddenly stood up and thanked Pei Xing Jian for the investigation. As Zhang Yuanshan confessed, Pei Xing Jian punished him, and the owner of the calf, Qiao Liunian, finally got back what belonged to him.

Pei Xing Jian also stated that the real cattle thief was present and said that if he counted to three, the guilty party should confess voluntarily. At that moment, unexpectedly, Han Si stepped forward.

Han Si knelt on the ground and admitted to all his crimes. He explained that every time he hurriedly went to treat the livestock of the common people, but they never paid him for his medical services. He always used the best medicinal materials, and of course, he needed to eat as well. While Pei Xing Jian claimed to punish Han Si verbally, he also intended to seek justice for him.

They couldn't let a good person like Han Si be buried like this. When the common people learned about the situation, they applauded and praised him. Lu Li returned and happened to witness this scene. Pei Xing Jian and Lu Li shared a smile. Bai San also greatly admired Pei Xing Jian's actions, and after this incident, Bai San willingly admitted to being a traitor and pledged unwavering loyalty to Pei Xing Jian.

Han Si also told Pei Xing Jian that his cattle thefts were not for profit but to test medicines using the stolen cattle and sheep. When Wang Chongyu's father learned that Wang Jun Meng had revealed everything to Lu Li, he became furious and believed that he had been deceived by Lu Li. He was certain that everything would be clear in front of Pei Xing Jian.

After Lu Li returned and informed Pei Xing Jian of the situation, they needed to come up with a strategy. They had to protect the wives and children of the Aijia family while gaining the Emperor's acceptance. They still needed to plan carefully. Princess Dachang always kept the Aijia family's wives and children with her to use them as leverage against the Aijia family.

Lu Li handed the written message to Mirror Maiden, who liked it very much. Lu Li confirmed with Mirror Maiden that if Wang Chongyu discovered the suffering of his wives and children in Chang'an, he would definitely rush back and unleash a bloody rampage. Afterward, Lu Li visited Mistress Liu and, although they didn't find her cousin, Mistress Liu was grateful for their help.

Mistress Liu also gave Lu Li some medicine that could induce a false death, hoping that they would find it useful.
