Di Renjie's appearance as both an official and a gangster really frightened Guard Chen. In a panic, he revealed that he had taken money from people and released Li Han privately ten days ago. As for the person who spent money to redeem Li Han, he was wearing long clothes and a bamboo hat. And with the black veil on his face, it was impossible to identify his appearance. After confirming that what Chen Guards said was true, Di Renjie took Qiao Tai and left first. Qiao Tai felt that Li Han had the motive to kill because he hated Anemone.
Later, Di Renjie stepped into Mingyuefang and asked Cao An about Fengyue. Cao An lit a stick of incense for him and played a pipa song. In just one song, he understood the heart of an infatuated man and a resentful woman. When Di Renjie woke up and rushed to Teng Mansion, he saw that he was completely white. Seeing this, the housekeeper hurriedly asked Di Renjie for help, saying that Teng Kan had locked himself in the anemone room and had not had any water or rice for a day.
Di Renjie gradually learned that Anemone and Tengkan slept in separate rooms during his lifetime, and found that Anemone was good at writing poems. In comparison, Tengkan's revised poems were slightly inferior. Tengkan invited Di Renjie to the side hall to talk on the grounds that he missed people after seeing things. Di Renjie noticed the riding whip hanging next to him and heard that Tengkan had given up martial arts and followed literature in his early years.
During the conversation, Di Renjie revealed to Tengkan that Li Han had pursued Anemone, and because Anemone hated him and was a nuisance, he designed to have him wrongly imprisoned. It is inferred from this that the evil spirit that has appeared frequently in Li's house recently is Li Han, and he is the most suspected of killing Anemone. Tengkan was very angry about this and expressed his gratitude to Di Renjie, hoping that he could find out the real murderer so as to comfort his deceased wife's spirit in heaven.
Because Tengkan was obsessed with writing poetry, he often didn't leave his room for several days, and he didn't know much about the whereabouts of Anemone. The housekeeper revealed that his wife and Mrs. Lai have been in frequent contact recently and often return to her parents' home. Di Renjie noticed something strange and recalled that Mrs. Lai had looked down on Anemone. The two had long been at odds and had completely broken off contact.
Thinking of this, Di Renjie asked Ma Rong about a place specifically for lovers to meet. Ma Rong took him to the Flower House and showed Ba Zong's token. The landlady admitted that there were indeed rooms for concubines. Di Renjie observed the writings on Anemone and the lotuses painted by Xu Kai on the wall, and even found sharp claw marks outside the window. He speculated that Li Han might have witnessed the sexual intercourse between Anemone and Xu Kai, leaving traces of anger.
After Di Renjie confirmed that Yinlian had met Xu Kai before leaving the cabinet and truly fell in love with him, he visited Lai Erniang again and told the truth of the matter. Mrs. Lai denied that she was wishful thinking and emotionally tore up Xu Kai's paintings, further confirming Di Renjie's suspicion.
Di Renjie asked Ma Rong to use the third token to ask Ba Zong to release the news that Anemone was not dead, so as to lead out Li Han who was hiding in the dark. As soon as this news came out, the people in the city were talking. That night, Li Han sneaked into Teng Mansion to look for Anemone. When he found out that he had fallen into a trap, he was attacked by Di Renjie and others and had no time to escape.
At the critical moment, Tengkan appeared and killed Li Han, claiming to avenge Anemone. Di Renjie noticed that Li Han was chanting Anemone's name before he died and put his hand on the cloth bag on his chest. He personally checked his nails and was surprised to find that they did not match the scratches on the window frame. This major discovery shocked Di Renjie. In order to verify his guess, he went to Cao An for confirmation, and he found a new breakthrough.
Di Renjie hurriedly returned to the autopsy room and analyzed the existing clues to believe that the murderer was someone else. Early the next morning, Di Renjie came to Teng Mansion and saw the servants busy carrying boxes. After asking, he learned that Teng Kan was preparing to leave Penglai City. He found Li Han's left purse in the flower garden. There was a lock of hair in it, which was the severed hair on the top of Anemone's skull, which was enough to show his deep love for Anemone.
Tengkan hadn't noticed anything strange about Di Renjie yet, but still looked sad, so he ordered his slaves to throw away the four-painted screen. Di Renjie subconsciously asked the name of the person who made the four-lacquer screen, but failed to get an answer. As night falls, Qiao Tai practices boxing shirtless, with the whip marks on his back clearly exposed, reminding Di Renjie of the riding whip hanging in Teng's mansion. At this time, Hong Liang made a major discovery - he found the poisonous plant pyrene mangosteen from the stone soil at the crime scene.
