After the little girl Maomao was rescued, she hugged Jiang Xiaohai tightly and called “uncle”.The man suddenly reacted and took out a dagger and swung it in the direction of the little girl. Fortunately, Zheng Bei had quick eyesight and quick hands, and immediately stepped forward to block. During the fight, a bloody streak was cut on his arm, and he finally subdued the gangster.For this reason, Zheng Bei knew that the little girl was Jiang Xiaohai's niece. Jiang Xiaohai was very grateful to Zheng Bei, but they did not find a man silently observing nearby.

Now, as a drug expert, Gu Yiran would take members of the task force to class every day after get off work to absorb knowledge. When everyone looked at the chemical formulas on the blackboard, they felt that the knowledge was beyond the scope, their heads hurt, and they collapsed.After a few days of getting along with each other, Gu Yiran's "Smiling Tiger" personality was fully revealed. He often looked smiling, but in fact he was cold and rigid at heart.The hard-working people in the task force, headed by Zhang Xueyao, were very disgusted with this outsider “nerd”.

While everyone was discussing Gu Yiran behind his back, Gu Yiran and Zheng Bei came in from outside.Gu Yiran smiled and did not blame, but counterattacked these people calmly as he spoke, which made Zheng Bei sigh with emotion. He must never offend intellectuals in the future, otherwise he would not even know if he was scolded by the other party.

At this time, Jiang Xiaohai took the initiative to find Zheng Bei at the police station, personally delivered medicated oil to him, and invited him to have a meal at home to express his gratitude.Zheng Bei felt that there were still some doubts about Jiang Xiaohai, so he agreed and went to Jiang Xiaohai's sister's house as a guest after get off work.

Sister Jiang was very grateful to Zheng Bei for saving her daughter Maomao and cooked a table full of food.Jiang Xiaohai's brother-in-law came back from outside and bought things for his daughter. He also wanted to give money to Zheng Bei, but Zheng Bei politely refused.While Zheng Bei was eating, he asked Sister Jiang some questions about opening a pharmacy and found that Jiang Xiaohai knew many folk remedies for treating diseases.

At the same time, Zhao Xiaoguang went to Zheng Nan's barber shop to get a haircut. The two chatted a lot. Suddenly, the shop tripped, and Zheng Nan held a candle to help him light up the repair switch.Seeing Zheng Nan's beautiful face set off by candlelight, Zhao Xiaoguang was even more moved. After repairing the electric switch, he proposed a candlelight dinner, but Zheng Nan wanted to go out for a meal with him.

After eating, Zheng Bei returned to the task force and found Gu Yiran writing “textbook” carefully.Gu Yiran greeted Zheng Bei with a smile, his face full of exhaustion. He felt that his class was indeed too boring to attract everyone's attention, so he wrote lesson plans overnight and racked his brains to make the content more interesting.Zheng Bei sat next to Gu Yiran and felt that he was a very gentle person, and he probably didn't have the temper of a man at all.

Then Zheng Bei led a task force to the entertainment city to catch drug dealers. Everyone was wondering how he brought Gu Yiran with him. Zheng Bei said that he would let Gu Yiran participate from now on.It was precisely because of Gu Yiran's professional knowledge and proficiency in slang that he was able to successfully gain the trust of lamp holder Li Shengbiao and arrest him. The members of the task force were convinced and had a great change in their view of him.

Zheng Bei and Gu Yiran cooperated tacitly, and after interrogating Li Shengbiao, they successfully learned the whereabouts of A Liang.Ding Guozhu extracted the fingerprints from the gold chain, which basically confirmed that A Liang was the murderer of Xiaobailou. It happened that Brother Xiong also brought A Liang's identity information, and the members of the task force lurked at the transaction location, preparing to arrest him.

Ding Guozhu was responsible for observing and locking the target on the roof of the building and reporting the location to everyone in a timely manner. The rat took the place of Li Shengbiao and contacted A Liang to pick up the goods. However, A Liang saw through it and fled crazily on a motorcycle.The members of the task force surrounded him, and Zheng Bei chased him in a car, but was forced to stop due to the train crossing. In the end, they saw A Liang being assassinated by a man wearing a helmet. When they came to A Liang, the man had already disappeared without a trace.
