Episode 4 recap: Yang Cai Wei got Pan Yue drunk.

Early in the morning, Shang Guan Lan returned to the capital city, leaving a large sum of money for Yang Cai Wei, as well as a maid hired overnight. However, these favors made Yang Cai Wei feel guilty, and she wondered how she would explain the truth to Shang Guan Lan in the future. Shang Guan Lan moved out of the house and went to the county yamen, telling Pan Yue that she would be sleeping on the streets. Pan Yue agreed, but secretly intended to force her to leave. Despite officially starting his new position the next day, Pan Yue went to the county yamen. The yamen attendants who were gambling were startled when they saw him, especially because one of them was among those who had attacked Yang Cai Wei before.

The attendant informed Pan Yue that there was a protectorate office in Heyang, and the details of the case were not important as long as they favored the four major families. Pan Yue ignored his words and ordered him to be taken away as a warning to others. Yang Cai Wei was initially watching the scene unfold, but Pan Yue sent her to beat the man. Yang Cai Wei took the board and struck him with all her might until it was done.

Pan Yue used this incident as a warning to others and asked Yang Cai Wei to come find him the next day. Ling Er helped Yang Cai Wei prepare her bedroom nicely, which was next to Pan Yue's room. Yang Cai Wei thought that she had successfully hooked Pan Yue's attention, so Ling Er found her a set of clothes covered in patches to attract his attention.

Pan Yue asked about the incidents that occurred during their wedding, and Yang Cai Wei casually made up a few sentences. Pan Yue then instructed her to assist the chief clerk and not to leave his side without permission. Yang Cai Wei followed Pan Yue, but she couldn't shake the feeling of being monitored.

While accompanying Pan Yue on inspection rounds, a woman suddenly stopped the horse carriage in the street and publicly insulted Pan Yue as a corrupt official. Soon after, a gorgeously dressed man arrived to apologize, but the woman continued to verbally abuse Pan Yue. Yang Cai Wei and Pan Yue noticed a wound hidden under the woman's sleeve, realizing that she intentionally did this as a cry for help. Yang Cai Wei urged Pan Yue to take strict action.

However, Pan Yue did not intervene. Instead, he directed Sun Wancai to take full responsibility for his wife's actions. When the woman spoke out again, Yang Cai Wei recited the laws and regulations and had Sun Wancai take the punishment on behalf of his wife. Someone nearby reminded Pan Yue that this woman was from one of the four major families, but Pan Yue still had her arrested.

This act earned praise from the people.

After Pan Yue arrived in Heyang, many people gave him gifts, and he subsequently hosted a banquet for many friends. Yang Cai Wei was eager to investigate Pan Yue's crimes and went to the archive to search for the file on Shang Guan Zhi's death. However, she was informed that Pan Yue had taken the file away that day.

Yang Cai Wei went to Pan Yue's room, thinking she had hidden herself well, but he had already discovered her presence. Gu Yong, the head of Jishan Hall, Cai Sheng, the head of the Life and Death Alley, and Qing Di, the head of the Hundred Flowers Palace, discussed important matters together, but someone from the Yinyin Rain Tower was missing.

Sun Wancai was arrested, and they decided to show their friends some colors. In order to obtain the key, Yang Cai Wei went out alone and realized she was being followed by Pan Yue's subordinates. She hid and let someone engage them, allowing her to escape. Yang Cai Wei asked Bai Xiao Sheng to help her get a jar of strong wine, and he also brought some news. She had inquired about Lao Jiangtou's whereabouts.

Back at the county yamen, Yang Cai Wei discovered that people from the four major families came to give gifts to Pan Yue. She eavesdropped on their conversation and overheard Pan Yue talking about the price to release Sun Wancai. Yang Cai Wei arranged a banquet to entertain the officials and staff of the county yamen, allowing them to get closer to Pan Yue. Ling Er took the opportunity to pour a cup of wine for A Ze, and after three rounds of drinking, everyone fell asleep. Yang Cai Wei secretly got up, woke Pan Yue, and took the opportunity to retrieve the key from him.

Upon opening Pan Yue's chest, Yang Cai Wei found a portrait of herself and Lao Jiangtou, as well as the file on the case, which mentioned the presence of water stains near the body without knowing where they came from. After Yang Cai Wei left, Pan Yue, who had pretended to be drunk, woke up.

The presence of water stains near the body was very strange. The next day, Pan Yue made an appointment with Yang Cai Wei to go out and mentioned her helping him back to his room the previous night. Yang Cai Wei didn't understand where he was taking her, but Pan Yue said he had found the robber who had injured her a month ago and wanted her to identify the person.

Yang Cai Wei's excuse was that she encountered a robber while driving away that day, but now faced with various evidence, it was not very convincing.
