Episode 5 recap: The Monkey Demon seeks revenge, and every household buys talismans.

Song Dian, a mission person, punished the quick capture class, and Song Dian gave the executor a set of fangs. The neighbor entrusted Peng You to give something to Qu San Geng, claiming that it was specially prepared for him by his mother. When he opened it, it turned out to be a pile of lime powder. His colleagues said that in five days, they would inevitably face punishment, but today they must first strike back at Qu San Geng ahead of time.

Xia Bu Tou was sent by the Nian Tai to supervise the case. He asked someone why they treated him as an outsider, and he directly slapped him several times, forbidding him to engage in private fraud. He then ordered them to be whipped again. He came here for a month, while Qu San Geng, who was being beaten, confessed that he found out about the corpse on the river. The person's name was Chen Wang.

Xia Bu Tou mocked him as a useless person who was far inferior to his master. Qu San Geng said that he had disbanded the visit and interrogation teams for Xia Bu Tou. Xia Bu Tou panicked when he heard this. It turned out that a few days ago, Qu San Geng and his men had taken down the Wu Hou Mansion. Jin Er Ge said that this move by Qu San Geng would surely provoke dissatisfaction among others, after all, it cut off their source of income.

Xia Bu Tou confirmed the situation with Song Dian, and Song Dian directly gave him the fangs, stating that the five of them were deeply guilty and could not be questioned by the county government. Xia Bu Tou said that if the Wu Hou Mansion was gone, how could he continue the investigation and lost his source of inside information.

Feng Ke Zhui was preparing a method to make paper look old, but unexpectedly, the treasured painting that he pretended to be his uncle's collection was taken away, and he imitated the calligraphy of ancient people, which was then snatched by people who couldn't recognize paintings. Qu San Geng learned that Feng Ke Zhui could imitate other people's handwriting, so he asked him to imitate Cheng Yi Zhi's handwriting. He handed him a fake prescription, and at a glance, Cheng Yi Zhi recognized that it was not written by him because the prescription contained poison. Qu San Geng continued by saying that Chen Wang and Lu Yuan Bao were poisoned to death. Cheng Yi Zhi, in a panic, explained that Chen Wang died by jumping into the river, but suddenly realizing that he had slipped up, he had to admit that Lu Yuan Bao was poisoned to death by his own younger brother.

Qu San Geng said that the prescription was found in the case file, and he hoped that Cheng Yi Zhi would tell the truth, otherwise, there would be other prescriptions in the future. Upon hearing this, Cheng Yi Zhi turned around and advised Qu San Geng to take some medicine to reduce the fire and not to invite trouble upon himself.

Xia Bu Tou reassigned the cases, but Qu San Geng's case was the only one excluded. Xia Bu Tou claimed that Qu San Geng had a sharp mind and could specialize in investigating cold and difficult cases. On the surface, his colleagues thought that Xia Bu Tou was favoring Qu San Geng, but in reality, he was trying to discipline Qu San Geng. Afterwards, a colleague pretended to give Qu San Geng something similar to what his mother had given him, and when he was caught off guard, he sprinkled lime on him and beat Qu San Geng severely. Fortunately, Song Dian appeared in time and saved him.

Qu San Geng offended Xia Bu Tou, so Leng Gui Er remembered that her father had said before that if you want to control someone, you should target their weaknesses. And Xia Bu Tou's greatest fear was not being able to solve a case by the deadline, while his strength was his experience. Qu San Geng came up with a plan to deal with Xia Bu Tou.

Housekeeper Zhang requested to see Song Dian, deliberately bringing him aside to indirectly show him the interrogation of Hao Daqing's case. The case mainly involved the renting of farmland at an extremely low price. Hao Daqing claimed that the other party rented the land to him at a low price because he was an orphan and a widow who couldn't cultivate the land. However, Song Dian didn't believe that they would rent it to him so cheaply. Song Dian sarcastically suggested giving the water fields to Hao Daqing, while Hao Daqing offered to leave a two-foot square piece for the other party.

Suddenly, the sack Hao Daqing was wearing started itching. Song Dian planned to exchange two feet of his skin for an acre of water fields. Upon hearing this, Hao Daqing immediately confessed and was given fifty lashes. Song Dian wanted to inquire about the house in Yan Zhi Lane, but Zhang Ji Zu had already anticipated this idea and insisted that the neighboring land was bought at market price, but later the neighbor regretted selling it cheaply. Besides, the case had already been closed.

Song Dian found Zhang Ji Zu's tone to be harsh, so he suppressed his anger and let him leave. Shi Cong noticed that the Huo Ji shop had talismans posted all over, claiming that the corpse in the river was the work of a monkey demon. Shi Cong also expressed his desire to buy talismans. The shopkeeper's house was burglarized, and it was discovered that the neighbor, Tao Huiwen, was responsible. Originally, this house belonged to Tao Huiwen's family, but because of her husband's gambling habit, they had to sell off some of their assets. Tao Huiwen frequently visited Wang Zhang Gui's house. Shi Cong found some things in the pawnshop and brought out a phoenix hairpin for Wang Zhang Gui to identify. It turned out to be the hairpin that Wang Zhang Gui had recently reported stolen. It was revealed that Tao Huiwen had taken many valuables from his house over the past six months through the front door, and Shi Cong suspected her of being the thief.

Wang Zhang Gui was in a panic and sweating profusely, begging Shi Cong to drop the case. He claimed that he was only trying to help Tao Huiwen and had secretly taken his wife's jewelry to give to her. Unfortunately, his wife reported it to the authorities. Shi Cong deduced the relationship between Tao Huiwen and Wang Zhang Gui and agreed not to pursue the matter further, on the condition that he buys five bottles of golden wound medicine.

Leng Gui Er came to find Qu San Geng and cautioned him not to help Leng Rui get into fights. She mentioned that he had already lost a fight with Hai Zi from Liu's shop and claimed that he wanted revenge. Shi Cong advised him to act quickly if he wanted to confront Liu's shop, as people already believed in the existence of a monkey demon, and they closed their doors early. At that moment, Liu, the shopkeeper, was buying talismans and asking a Taoist about the origin of the monkey demon. The Taoist claimed that the monkey was killed by Leng Bu Tou and that it had come for revenge.

Twenty years ago, a monkey performer appeared on the street, and the students were so captivated by the monkey show that they neglected their studies. The performer chased the truant students all over the street. The performer blamed him for driving away the audience and not receiving any money. Mr. Wang kindly asked everyone for a reward, but he was insulted by ruffians and scoundrels. In a fit of anger, Mr. Wang used a ruler to strike Shi Liu. Leng Wujie arrested the monkey performer because he engaged in nighttime theft. The monkey took advantage of an open window to enter his house, leaving behind its footprints, and the performer was later beaten and died from the punishment.

Rumors spread that the monkey had been abducted from the mountains by the performer, and in order to seek revenge, the monkey pushed the performer into the river.
