Zheng Bei arrived at the Huazhou Police Academy Research Institute. When he saw Gu Yiran's young face, he was suddenly dumbfounded and speechless. Especially when he learned that Gu Yiran was two years younger than himself, he couldn't help but sigh that he was young and promising.However, Gu Yiran was distant in his polite manner and did not agree to go to Haran to investigate the major methamphetamine case. After a few words, he took the documents and went about his own business.

Originally, Zheng Bei didn't even want to involve experts, so he called Gao Linsheng to report, planning to pack his things and return to Halan immediately.However, Director Zhao specially borrowed a complete set of chemical equipment from the province for this case, so Gao Linsheng gave Zheng Bei a death order to bring in this drug chemistry expert no matter what, otherwise he would not be able to return to Halan.

Back then, Gu Yiran analyzed the formula of methamphetamine, and Zheng Bei seized a pack of crystals, which destined the two to meet today.But now Gu Yiran has long since shed his childishness and become mature and capable. He is no longer as taciturn as before. On the contrary, he smiles and appears kind and gentle, but he is distant from others.

Although Zheng Beixin was unwilling to do so, he still forced himself forward, doing morning exercises in the morning, the canteen at noon, and getting off work at night. He even had to accompany him when he jogged on the playground, talking loudly while running, hoping that Gu Yiran couldJoin the task force.Gu Yiran still looked like a boy with a fake smile, speaking like a spring breeze to him, but resolutely rejecting him in attitude.

In the end, Zheng Bei had no choice but to hand over the methamphetamine information to Gu Yiran, saying that he was going back to Haran tonight and wanted him to think about it carefully.Gu Yiran looked through the documents carefully, and the previous case flashed through his mind, so he packed his luggage without hesitation to find Zheng Bei and flew back to the Northeast with him.

Since Gu Yiran was born and raised in the south and did not understand the weather in the Northeast at all, he started sneezing as soon as he landed, so Zheng Bei personally drove his family's cart to take him to the police station to report.During this period, Zheng Bei was curious about why Gu Yiran suddenly agreed to join the task force. Gu Yiran kept silent about the previous events and lied that the school leaders sent him to assist in the work.

After arriving at the police station, Zheng Bei enthusiastically introduced the task force to Gu Yiran. Unexpectedly, Zhao Xiaoguang and the others actually turned Lao Po's abandoned No. 1 canteen into a task force, which made him feel a little embarrassed.At this time, Brother Xiong came in from outside and took everyone to see Gao Linsheng. However, Gao Linsheng thought that Zheng Bei did not invite Gu Yiran, so he left the guest house early and asked him to find a way to arrange a place for Gu Yiran.

The drug dealer that the major case team had been tracking for half a year finally made some news. The other party planned to trade today, and this time Boss Xie and the Xiaobailou massacre were both from eastern Guangdong.Zheng Bei informed everyone to put on makeup and investigate as soon as possible, leaving only Gu Yiran, but Gu Yiran insisted on participating in the arrest operation.

In the car, Zheng Bei told his informant Mouse to secure the opportunity to make a crime, and learned through him that Boss Xie was quite lustful.Zheng Bei then disguised himself as a trader and followed Mo Zi to the Pattaya Resort Hotel. Because he had learned a few authentic vernacular words from Gu Yiran beforehand, he quickly dispelled Boss Xie's suspicion.Boss Xie found two women to celebrate. Zheng Bei deliberately showed the beads in his hand and lied that he would not touch women before doing important things.

At the same time, Gu Yiran and others were sitting in the car outside, using a bug to obtain the contents of the conversation.Zheng Bei discovered that there was a grenade hidden in Boss Xie's room. Gu Yiran quickly informed Zhao Xiaoguang and Zhang Xueyao to be careful. Zheng Bei responded accordingly, pretending to be very interested in this thing and offered to spend money to buy it.

Boss Xie told Zheng Bei that people walking at night must rely on these things to defend themselves, and they cannot sell life-saving things.Zheng Bei didn't force it, and waited for Boss Xie's subordinate Tietou to pick up the second batch of goods. He paid with one hand and took the goods with the other, and the two parties reached a cooperation.In the bug, Zheng Bei wanted to take Boss Xie to experience the local bathing culture. Gu Yiran couldn't help but raise his lips when he heard Zheng Bei talking about the %out-of-body experience he taught.
