Episode 12 recap: Yan Xiang's father was brutally murdered.

Ji Chu brought in Yan Xiang's maid to identify the situation, but the prison guard that evening claimed that she was not the maid who came to visit Yan Xiang that night. The maid, Xiuxiu, quickly knelt down and explained that she did intend to visit Yan Xiang that night. However, when she was at the entrance, she was suddenly knocked unconscious by a masked person. When she woke up, she was already in the mansion.

Upon learning of Yan Xiang's murder, Ji Feng was extremely surprised. Moreover, since it was still unclear whether it was a suicide or a homicide, Ji Feng became even more anxious. He kept muttering about the separation between humans and ghosts and asked them not to bother him. Hua Qing Ge and Ji Yun were still searching for clues in the prison, but even though Hua Qing Ge and herself had been in the prison all along, they had no inspiration. Furthermore, the prison guards said that they couldn't see anything in the blink of an eye. Hua Qing Ge suddenly thought that perhaps after someone had knocked Xiuxiu unconscious, another person had come and killed Yan Xiang.

Afterward, Hua Qing Ge and Ji Yun also went to find Ji Chu. Lin Xi Yao happened to be there too. Lin Xi Yao had reinvestigated and discovered that Yan Xiang had been poisoned. The reason they hadn't found anything earlier was probably because the pastries brought by the maid temporarily suppressed the poison. At this moment, the main suspect named Chang Xun had also disappeared without a trace. Hua Qing Ge was somewhat confused about the current situation.

Hua Qing Ge had been following Lin Xi Yao, wanting to find the culprit together. At this moment, Du Wen Shu handed a book to Hua Qing Ge, hoping that it would provide some inspiration. Now, they had to prove the existence of the demonic poison. Only then could they prove that Ji Chu's mother's case years ago was also a malicious setup.

Ji Chu also arranged for subordinates to identify the portraits of the maids around Wei Guifei. After all, there were two Xiuxius now, and they could start from this clue. The prison guards also recognized the person, and Ji Chu immediately sent people to capture her. It seemed that this case involved a wide range of people. Hua Qing Ge took the opportunity to create more opportunities for Ji Yun and Lin Xi Yao, hoping that their relationship would not be affected.

The guards arrived at Wei Guifei's sleeping quarters and requested to take her maid for questioning, but Wei Guifei refused to comply.

Yan Xiang's father was deeply saddened. He never expected his daughter to be inexplicably murdered. Just then, a masked person suddenly broke into the sleeping quarters. The guards approached the maid, but she pretended to be seriously ill, making it impossible for them to take her away.

Hua Qing Ge stood at the door and watched Lin Xi Yao and Ji Yun discussing Yan Xiang's case. She hoped that the two of them would have a good discussion about their relationship. However, Ji Chu suddenly stood behind Hua Qing Ge. Hua Qing Ge quickly asked Ji Chu to leave, not wanting to disturb them.

As soon as Hua Qing Ge went out, the guard came and informed him that the maid couldn't come for questioning due to illness. On the way back, Hua Qing Ge pretended to be asleep, intentionally creating an opportunity for Lin Xi Yao and Ji Yun. The next day, Ji Yun received a notification that Yan Xiang's father had been killed. Hua Qing Ge went along as well, but there was no mention of Yan Xiang's father's case in her own novel.

Later, Ji Yun's subordinate informed him that only Ji Chu had visited Yan Xiang's father the previous night. They went to find Ji Chu together, but Ji Chu denied any involvement in the murder. At that moment, Lin Xi Yao stepped forward and said that the killer used their left hand to slit the throat, and the only person who would use their left hand was Chang Xun. Soon, the guard found Chang Xun fleeing on the street. Chang Xun admitted to the murder. Ji Chu asked if this was related to Wei Guifei, but Chang Xun vehemently denied it. It became clear to everyone that Chang Xun was just a scapegoat, and Ji Chu's mother's case would not be vindicated.

At this point, Yan Xiang's father's servant handed something over to Ji Chu and said that before he left, the master instructed that if he didn't return, this item should be given to Ji Chu. In fact, Ji Chu had informed Yan Xiang's father about the demonic poison inside Yan Xiang. Yan Xiang's father, knowing he was doomed, left a letter stating that he was bewitched by Wei Guifei.
