Episode 23 recap: Yang Cai Wei and Pan Yue's arrangement led to the exposure of the spy.

Pan Yue handed over the Silver Rain Tower to the Chamber of Commerce for management. In the evening, he specially hosted a banquet to thank everyone, but in reality, this was a scheme orchestrated by Pan Yue and Yang Cai Wei. Yang Cai Wei pretended to have drunk too much, and Pan Yue escorted her back to her room, believing that the spy would take action.

However, Yang Cai Wei was somewhat conflicted. After all, they had been together for a long time. Could there really be a spy among them? After Yang Cai Wei and Pan Yue left, the Chief Steward and Officer Liu found excuses to leave one after another. When the time came, Pan Yue led his men to search for the spy. Officer Liu's expression was extremely uneasy, and evidence was found in his possession.

The Chief Steward expressed his desire to retire and return to his hometown, and Pan Yue agreed. The Chief Steward then asked about Officer Liu's situation, and Pan Yue said that there are laws in the country and rules within the family, and those who do wrong must be punished. The Chief Steward pretended to leave the county office in a weak state and headed straight to the back mountain of the Silver Rain Tower, where he found the evidence left by Zhuo's father.

Pan Yue had A Ze waiting there for a long time. In fact, Pan Yue had long known that the spy was the Chief Steward, so he designed a trap for him. The Chief Steward did not confess everything but instead took poison and died. However, Pan Yue discovered a letter left by Zhuo's father and speculated that he wanted to leave himself a way out, so he did not hand the letter over to the person behind the scenes.

Upon seeing the contents of this letter, Yang Cai Wei's emotions became unsettled. The fate of their family had changed because of this letter, and now it was back in her hands. Officer Liu knew that Pan Yue's capture of him was a strategy, and he also suspected that there was a spy in the county office. This made him even more impressed with Pan Yue.

Yang Cai Wei and Pan Yue arrived at Wangyue Bridge to inquire about the people who came to the capital city ten years ago from the local shop owners. However, they were interrupted by the shopkeeper's wife. Yang Cai Wei had to ask Pan Yue to distract the shopkeeper's wife with his charm. The shopkeeper informed them that he had indeed seen a merchant girl, and she was beautiful. However, he died during the revival case of the Heavenly Master nine years ago, and she was one of the eight deceased.

Upon hearing this, Yang Cai Wei became frightened because this incident happened just a year after she arrived in Heyang. She had accompanied her master to the scene and was greatly scared at the time, to the point where she didn't dare go out alone for a long time. Pan Yue didn't expect such an eerie connection, and the two of them began to investigate the case files. The eight deceased women in Heyang corresponded to the eight trigrams. After their deaths, the people of Heyang became fearful, but they never expected that the merchant girl was the one who had informed Yang's father.

It is rumored that the murderer is a disciple of the Luo Yun Sect, and the head of the sect is called Xue Jianli. There is a female disciple named Lu Ai Ge under his sect, and both of them are respected by the people of Heyang. Later, when the officials searched the Luo Yun Sect, they found a manual that recorded the method of achieving immortality through human sacrifice. However, Lu Ai Ge had already died before the first victim appeared, and then the legend of the Heavenly Master's resurrection and the murders began.

Yang Cai Wei remembered that her master was involved in the case as a coroner and decided to go find him for inquiries. The two of them went together to the home of Bai Xiaosheng in the outskirts of the city, but the master was not there. When Yang Cai Wei went to find someone, the master suddenly burst out and chased after Pan Yue. Yang Cai Wei quickly explained the misunderstanding.

The master had many grievances against Pan Yue and deliberately drove him out to water the fields. He avoided the topic during dinner. The two of them slept there at night, but Pan Yue couldn't sleep because of the master's snoring. He secretly met with Yang Cai Wei in the courtyard. Yang Cai Wei had prepared wine specifically for Pan Yue. In fact, the master was a kind person who treated her like a daughter and was naturally concerned about her.

When Yang Cai Wei was falsely accused of stealing something in the past, the master helped her as a witness. Since then, Yang Cai Wei insisted on following him and became his disciple. Sun Zhen had mentioned to Zhuo Lanjiang that he had not seen the person behind the scenes, but only delivered something to a pawnshop in the capital city. Zhuo Lanjiang came to the pawnshop alone but did not see that person.

Bai Xiaosheng also followed along and bravely expressed her feelings to him, but Zhuo Lanjiang insisted that she leave. Pan Yue distracted Yang Cai Wei as there were some things he wanted to discuss alone with the master. Pan Yue understood the master's concerns and assured him that he would handle the matter regarding the princess well and hoped that he would trust him to take care of Yang Cai Wei. In the end, the master did not make things difficult for him.
