Zhang Baohuan visited Princess Yongan's Mansion with the intention of taking Han Shiyuan away.The princess appeared and stated that she only invited Han Shiyuan as a guest.Zhang Baohuan retorted, saying that both parties must be willing to be a guest, but Han Shiyuan was obviously unwilling, and mentioned that he met Shen Du and Yan Xing to protect him on the way.After hearing this, the princess generously agreed to Zhang Baohuan to take Han Shiyuan away, but also had a deep meaning: Fortunately, Yan could protect him for a short time, but it was difficult to guarantee that Han Shiyuan would be safe for a long time.

The subordinates came to Shen Du and solemnly reported the strange scene in Jinxiufang: a large number of moth-shaped gems suddenly appeared, accompanied by the mysterious appearance of an old friend, and the strange shapes were staggering.The people gathered one after another and knelt down to worship. It was rumored that shopkeeper Han had appeared. The scene was chaotic and fanatical.People rushed to pick up these gems, which seemed to bring good luck.

Yan Xing and Shen Du came after hearing the news and witnessed this scene. Yan Xing speculated that there must be an expert behind the matter and that it was widely involved.Shen Du was worried about Yan Xing's safety and persuaded him to give up the investigation, but Yan Xing was determined and vowed to uncover the truth.In the early morning of the next day, Yan Xing hurriedly went out and met Lu Chuichui for some fun, but actually he had other plans.

Shen Du knew Yan Xing's character well, so he arranged for Jing Lin to follow and protect him secretly.Yan Xing went to Chen's house and while talking with Chen Shouzheng, he learned about the rumors of the arrival of “Fire Moth”.She was keenly aware that the Chen family's old man's testimony was too consistent and was obviously rehearsed in advance.Unexpectedly, Chen Shouzheng suddenly used the powder, and Yan Xing fell into a hallucination, mistakenly thinking that the old man had escaped, and pursued him.When Jing Lin saw this, he quickly followed.

In the end, Yan Xing found the body of the Chen family old man in front of Mingsheng Temple. He was shocked, but was misunderstood by Princess Runing, who accused him of committing murder in the holy place and ordered his arrest.A storm seems to be brewing quietly.

After learning that Yan Xing was involved in the murder case, Shen Du was anxious and rushed to the scene immediately.At this time, Lai Luozhi had also arrived, claiming to take over the investigation of the case.After a heated debate between Shen Du and Lai Luozhi, the latter reluctantly agreed to postpone the interrogation of Yan Xing until the next day, giving Shen Du one night to find out the truth.

Shen Du carefully inspected the body of the old man from the Chen family and found that his shoes were clean and free of mud, and concluded that he did not go to the crime scene on his own.Lu Chuichui came anxiously and felt relieved to see Shen Du present.Shen Du then went deep into the Chen family to investigate and found that there were no signs of fighting in Chen Shouzheng's room, but the old man's bed was stained with blood, which was obviously the first scene of the murder.

In order to track down clues, Shen Du secretly investigated the whereabouts of the wise king, and was surprised to learn that he had secretly visited Mingshengguan to meet Princess Runing.Shen Du confronts Princess Runing and uses the whereabouts of the wise king as a bargaining chip, implying that if the truth is revealed, the consequences will be disastrous.The eldest princess was shocked and revealed that the wise king had indeed visited and confirmed that Shen Du did not commit the murder at the scene, but hinted that the wise king later encountered a box containing the body at the back door.Shen Du vowed that no matter who was involved, the Jinxiufang murder case would be investigated to the bottom of the case.

When Lai Luozhi was about to interrogate Yan Xing, Shen Du suddenly appeared, holding the hand sign of the Empress Dowager, and announced that the case would be taken over by the Imperial Household. Lai Luo Zhi had no choice but to give in.When Lu Chuichui saw that Yan Xing was safe and sound, his joy was beyond words.Shen Du once again persuaded Yan Xing to give up the investigation, but Yan Xing firmly refused and vowed to reveal the truth.She was well aware of Shen Du's concerns, so she said that if Shen Du was afraid of power, she would be willing to make a peace and leave the book, and go into danger alone without involving Shen Du.As soon as these words came out, Shen Du was angry that he ignored his own safety and left angrily, leaving Yan Xing alone with a firm gaze and vowed to find out the truth.
