Su Wuming asked Pei Xijun to go to prison to listen to Dugu Xia Shu telling about what happened in dreams and reality, and painted it on paper, and then helped him recall what reality is and what dreams are. Pei Xijun used his painting skills to paint what Dugu Xia Shu said into a scroll. One of the pictures is about Liu Youqiu killing Qinghong, and Lu Lingfeng believes that this statement has no basis at all. Su Wuming said that Pei Xijun's painting verifies that Dugu Xia Shu's mental state is indeed problematic, and he should have been plotted against.

Dugu Xia in prison insisted that it was Liu Youqiu who killed Qinghong. After Su Wuming's questioning, he stated the past that he had never mentioned. Two months ago, Qinghong went to the Confucian Temple to change clothes for Dugu Xia. It happened that Dugu Xia was out and had not returned. Liu Youqiu kindly took Qinghong into the East Hall of the Confucian Temple to rest. When Dugu Xia returned, he happened to see it and followed the two quietly. Seeing Qinghong in the city helping Liu Youqiu wipe the clothes wet in the rain, he misunderstood that the two had an affair.

Later, Qinghong frequently came to send her clothes to change. Once, Qinghong complained that Liu Youqiu trapped Dugu Xia Shu in the Confucian Temple. Although the two were studying poetry and books hard, they were clearly wasting their time and had no achievements, which made Dugu Xia angry. Then Liu Youqueued to comfort him and made tea for him. Uncle Dugu Xia then fell asleep. After waking up, Qinghong had already returned home.

Due to this matter, Dugu Xia Uncle Dugu Xia suspected that Liu Youqiu had given medicine to him. Later, he looked for an opportunity to test Liu Youqiu and asked Liu Youqiu to go home to get medicine for him on a rainy day. Liu Youqiu's words with Qinghong were indeed ambiguous in Dugu Xia Uncle's home, which made Dugu Xia Uncle Dugu Xia who followed him determined that the two had an affair. After Liu Youqiu returned to the Confucian Temple, the two quarreled. Dugu Xia Uncle guessed that Liu Youqiu must have wanted to elope with Qinghong later, and he would only kill Qinghong after being rejected by Qinghong.

Su Wuming could not determine whether what Dugu Xia said was true or false, so he had to ask Lu Lingfeng to go to the Confucian Temple to find auspicious verification. Lu Lingfeng met a beggar Donglang stealing in Jixiang's room at the Confucian Temple. After admonishing him, he drove him away. Later, Jixiang came back and Lu Lingfeng asked whether Dugu Xia's words were true or not, but Jixiang said that the fact was not the case that day. Qinghong did come to the Confucian Temple that day, but she broke the secret between the two disciples. When Lu Lingfeng heard about this, he rushed to prison and punched Dugu Xia Shu, saying that he did not have the same situation as Qinghong and Liu Youqiu at all that day, but Qinghong discovered the private relationship between Dugu Xia Shu and Liu Youqiu. Uncle Dugu Xia learned about this and was embarrassed and angry and committed suicide by hitting the pillar. Fortunately, he was rescued by Master Feiji in time.

Su Wuming accused Lu Lingfeng of acting too impulsively, and even Xijun thought so. Several people pondered the details of the case, and suddenly the arrester came to Linzhou to report to the documents that Lingjian had committed many cases ten years ago, but he was good at using steel needles and would die if he killed someone. The catcher also learned that Liu Youqiu's father burned himself to death at home tonight. Su Wuming came to Su's mansion to check it out and found through the autopsy that Liu's father was killed first and then burned. This case may be related to the previous case. Lu Lingfeng and Su Wuming both remembered the details that were missed before.

Jixiang packed his luggage and was about to leave the Confucian Temple to find a new future. Su Wuming waited for Jixiang at the door, expressing that he appreciated his mind and planned to recommend him to join the governor's office. Jixiang refused on the grounds that he did not want to rely on others. Su Wuming did not stop him, but let him leave. Lu Lingfeng pretended to be a bandit and intercepted Jixiang halfway, testing his identity to go on a career, and asked him to recite " Tengwang Pavilion Preface ". During Jixiang's recitation, Lu Lingfeng showed his true identity. Jixiang knew that his identity was exposed and attacked Lu Lingfeng with an umbrella as a weapon. Finally, with the cooperation of Lu Lingfeng, Fei Jishi and Xue Huan, he was successfully captured.

Jixiang was arrested and returned to prison. Su Wuming identified him as Ling Jian, the murderer of neighboring state ten years ago. Lu Lingfeng had already tested his steel needle hidden weapon. This time, he killed Qinghong and Liu's father and son was a death sentence. Before burning the Liu Mansion, he got the recommendation document paved by Liu's father for his son Liu Youqiu in the capital. He just wanted to go to the capital to fight for his career path.

Lu Lingfeng said that he found something strange from Jixiang's method of beating pheasants, so Jixiang had to admit his crime. He was originally an orphan and was taken in by his master to teach martial arts and hidden weapons. Later, his master died in the chaos in the world. After he took revenge, he wandered around in the world to avoid the pursuit and fled to a temple in the neighboring state to rename Lingjian. Later, he got tired of his original life and came to Nanzhou to donate money to build a Confucian Temple. Three years ago, Dugu Xia Shu lived in the Confucian Temple to study. Under the inspiration of Dugu Xia Shu, he fell in love with studying. Because Dugu Xia Shu praised him for his talent for studying, he believed that he would be able to pass the imperial examination and become a scholar. In this way, the life of a thief in the first half of his life and a second half of his life was exciting.
