Liu Rong went to the study to deliver mint cake to Xu Muchen. Xu Muchen was busy checking the files and somewhat ignored her.Liu Rong was so angry and annoyed about this that she snatched away all the quilts at night, leaving no bed for Xu Muchen.On the third day, Su Jinning brought clues to Liu Rong, saying that on the day of the murder in Hu Mansion, blood stains were found in the wing next to the wedding room, but the blood stains disappeared later.Liu Rong told Xu Muchen about the incident, hoping that he could successfully solve the case.Xu Muchen visited the Hu Mansion at night and reconstructed the shape of the murder weapon based on the traces at the murder scene, and used this as a clue to track down the real murderer.Liu Rong approached Xu Muchen to inquire about the case. Although Xu Muchen was tight-lipped, she accidentally saw the blueprint of the murder weapon.
Liu Rong drew another drawing from memory, and found out through her senior brother's silent words that it was the unique secret weapon of the killer Black Civet Cat.Xu Muchen found out the whereabouts of the black civet cat, which was located in the back hill of Wanfo Temple, and ordered Wu Zhao to lead Zichen Division to conduct control.Liu Rong wanted to investigate the black civet cat, so she made an excuse to go to Wanfo Temple to pray for Xu Muchen. After hearing this, Xu Muchen asked to go with her.In a small house in the back mountain, the black civet cat suddenly heard something strange outside the door. It turned out that it was Xu Muchen and the Liuye Thief who came to hunt him.The black civet cat jumped out and deceived during the escape, causing both Liu Rong and Xu Muchen to fall into a trap.
