Wei Daiqing was bent on meritorious service and promotion. When he arrested Deng Mingyuan, he was at the Hua Zhen family. Fearing that there were still remnants of the underground party, he investigated the situation of the Hua Zhen family members. The only suspect was Hua Zhen. On the third day after Deng Mingyuan was arrestedHe went to Shanghai and has not come back yet. This aroused great interest in Wei Daiqing. He once again interrogated Deng Mingyuan about Hua Zhen. However, Deng Mingyuan had also investigated Wei Daiqing and knew Wei Daiqing's original name. He caught Wei Daiqing's pigtails.Wei Daiqing did not investigate further.

When Luo Minmin came home from work on the first day, she saw a mess. A group of gangsters went to the house to cause trouble again. After helping her brother clean the house, Luo Minmin comforted her brother. In a few days, all the police officers from her four teams would come to the house to take photos.Since then, those little gangsters have not dared to make trouble again.After Hua Zhen returned home and finished eating, he told Meng Duoci some of the things he had investigated during the day. Meng Duoci was very grateful to Hua Zhen for helping her investigate the case, and was also very satisfied with the larger-sized clothes Hua Zhen bought for her..

Luo Minmin came to work and found that there was no women's locker room at all. Her teammates changed clothes without any scruples. Luo Minmin was frightened. She originally wanted to apply to the leader for a women's locker room, but after hearing that it would affect one month's salary, she immediately withdrew her application.During the regular meeting of the police station, Team 4 is still the least lovable character. Zuo Ronghua does not seek advancement and has no connections with higher-ups. Therefore, even though he is a “old man” in the police station and still has no hope of promotion, he does it for everyone every time.Tea and water were served, but there wasn’t even a stool.

This time the police station asked the fourth team about the Mandarin Hotel. Zuo Ronghua was not very clear about it. Chen Hao explained several clues he had investigated, but was intercepted by the senior leader. The meeting went to the end and it was the senior leader who made the decision.Hand over the case of Meng Duoci's family extermination to the city.Originally, the fewer difficult cases the better for Zuo Ronghua. When he heard that they were going to be handed over to the city bureau, he immediately organized the files, erased the code name of the case, and let the police officers concentrate on solving the next case.

Huazhen's fourth team got a clue. Someone saw a kidnapper appearing near a hotel. The team members were excited and nervous. This was their first mission. Chen Hao arranged for several team members toTask, let them arrest the suspect in plainclothes. Originally, the new police officers did not need to call the police, but this abductor was the person Hua Zhen wanted to catch. He was the one who escaped over the outer wall of the hotel that day. Hua Zhen took the initiative to call the police.This caused great dissatisfaction among the members of the Bai team, saying that Hua Zhen was overestimating his capabilities, but Hua Zhen issued a military order on the spot. If he could not catch the abductor this time, he would never send out police officers to perform tasks in the future.

Chen Hao was surprised that Hua Zhen took the initiative to apply for police dispatch. It seemed that Hua Zhen couldn't wait to investigate something.Luo Minmin was very nervous when she went to the police for the first time because she had no experience. In order to find the best observation angle, Hua Zhen went to a nearby cafe. The consumption here was high, but Luo Minmin still took out all the money in his pocket to buy Hua Zhen.After drinking a cup of coffee and seeing Luo Minmin's nervous expression, Hua Zhen told her to relax and then treated her to a piece of chocolate cake.

Hua Zhen saw the cake for the first time. Before she even took off her chopsticks, she heard a commotion outside. She rushed out before she could figure it out.This time, other team members made a mistake in arresting the wrong target.

Seeing that the suspect was about to escape, Hua Zhen quickly chased after him.In order to arrest the abductor, Hua Zhen rushed into the French Concession. Chinese police were not allowed to enter the French Concession. However, Hua Zhen did not care about these rules. After arresting the abductor, the French Concession police quickly came to investigate.The person who reprimanded Chen Hao was Shi Junli, Inspector of the Public Security Bureau Police Department. She asked Chen Hao to release the abductor and arrest Hua Zhen for questioning, but Chen Hao immediately stood in the way and said that the gate of the French Concession had not been repaired yet.The transitional area cannot yet belong to the French Concession.

After Chen Hao argued hard, the other party finally gave in.Chen Hao took Hua Zhen, several team members and the captured kidnapper back. On the way, he rebuked Hua Zhen for his recklessness and asked him what the purpose of his painstaking efforts to come to the fourth group was.
