Episode 24 recap: Yang Cai Wei and Pan Yue disguised themselves as a couple to investigate the case.

The master told them about the resurrection case of Tian Shi, where several victims had died in different ways. The master conducted a thorough investigation, but there was no mention of it in the case files. The county magistrate at the time wanted to quickly close the case and didn't believe the master's words. The eighth victim was Miss Shang, who had the most gruesome and painful death. The master concluded that their deaths were related to Lu Ai Ge. He had secretly visited Lu Ai Ge's grave and discovered a body, but he was discovered by Xue Jianli that day.

Everything seemed to be connected to Xue Jianli. Pan Yue and Yang Cai Wei decided to visit Luo Yun Men, where they saw many people coming and going, and Xue Jianli had many followers. Pan Yue and Yang Cai Wei had no choice but to pretend to be a couple to gather information and ended up standing in front of Xue Jianli.

Yang Cai Wei felt a chilling presence from Xue Jianli, as if there was something strange about him. The two of them settled down at Luo Yun Men first. Pan Yue knew that Yang Cai Wei felt cold at night, so he skillfully massaged her acupoints. Suddenly, someone flashed by the door and informed them that they were not allowed to leave Luo Yun Men at night.

Late at night, Pan Yue visited Luo Yun Men and discovered that Xue Jianli's room had a captivating scent. There was also a secret room in his room, from which chanting could be heard. Zhuo Lanjiang often woke up from nightmares, only to see Bai Xiaosheng. She had rented the eastern wing of the courtyard, much to Zhuo Lanjiang's dismay. Pan Yue and Yang Cai Wei tried various methods to enter Xue Jianli's room. Yang Cai Wei decided to distract Xue Jianli and let Pan Yue enter. Xue Jianli didn't want to say much to Yang Cai Wei until she mentioned that her sister was one of the victims in the case of the resurrection of the angels. Only then did Xue Jianli say a few more words to her before handing Yang Cai Wei over to his followers.

In the secret room, Pan Yue saw a woman who referred to Xue Jianli as the master and wished for death. She was Lu Ai Ge, and she hadn't actually died. Pan Yue hid in a corner and witnessed Lu Ai Ge biting Xue Jianli fiercely. Then Xue Jianli fed her a pill, and Lu Ai Ge became obedient like a puppet.

Suddenly, there was a voice outside saying that there was a water leak. Xue Jianli went out to check, and Pan Yue took the opportunity to escape with Lu Ai Ge. By the time Xue Jianli realized that Lu Ai Ge had gone missing, it was too late. Lu Ai Ge regained consciousness halfway and begged Pan Yue to take her away. She didn't want to be imprisoned anymore.

Pan Yue speculated that Xue Jianli and Lu Ai Ge had a relationship beyond just master and disciple. Lu Ai Ge said he was once the person she loved the most, and she joined Luo Yun Men after catching a glimpse of him. Their feelings deepened over time, and Lu Ai Ge changed her name. But when she expressed her feelings, Xue Jianli rejected her because of their master-disciple relationship.

Lu Ai Ge was determined to find a way to heal Xue Jianli, but sacrificing lives went against the natural order, so they agreed not to do it for eternity. However, Xue Jianli framed Lu Ai Ge by making her appear dead, shifting all the suspicion onto her. Lu Ai Ge decided to live in seclusion under an assumed identity, and Yang Cai Wei had Ling Er escort her away.

After they left, Yang Cai Wei and Pan Yue discovered inconsistencies in Lu Ai Ge's words. Xue Jianli had even advised Lu Ai Ge not to resort to methods that went against the natural order. Ling Er had been captured, and Lu Ai Ge intended to continue with the sacrifices. Xue Jianli rushed to stop her.

It was Lu Ai Ge who had been the one killing all along, and she did it all for Xue Jianli. But now she realized that Xue Jianli had no feelings for her, and she was determined to kill him. However, to her surprise, Xue Jianli willingly impaled himself on her sword. If he had no feelings for Lu Ai Ge, why would he grant her that name?

Xue Jianli died at the hands of Lu Ai Ge. Seeing this, she remained obsessed with immortality and even attempted to write talismans. But when she looked up and saw Pan Yue and Yang Cai Wei, she knew her end had come. She took her own life beside Xue Jianli. Ever since Ling Er's incident, A Ze had been by her side, fearing for her safety.

Lu Ai Ge had only killed four people; the remaining four were victims of someone imitating her. During the autopsy, Yang Cai Wei found a copper coin in the mouth of a victim. It seemed that this matter was related to Bai Hua Palace. The songstresses of Bai Hua Palace would place a copper coin in their mouths before death, hoping for a better afterlife. The two of them went to Bai Hua Palace, hoping that Qing Di would reveal everything they knew.

It turned out that Miss Shang was one of the songstresses of Bai Hua Palace and was like a sister to Qing Di. Every year, Bai Hua Palace would select a group of songstresses to send to the capital city, and that year they were chosen. Miss Shang had hoped for a better life, but they secretly returned after finding a book that revealed corrupt officials communicating with an enemy state. They had no choice but to hide and stay undercover. Miss Shang wrote a report to Yang's father, hoping he could take down the officials. However, she never expected Yang's family to be killed, and they had no choice but to go into hiding.

The other three sisters were killed one by one, and Miss Shang was terrified but didn't want to involve Qing Di. Since then, Qing Di had been sending songstresses to the capital city every year, fearing that any suspicion would arise. Pan Yue and Yang Cai Wei decided to accompany Qing Di to the capital.
