Episode 12 begins: Xiaohe cooperates with the police to find the motive for the crime. Zhang cheng was injured. The video of Xiaohe going to the bus company and Wang Xingde's dormitory before was discovered by Zhang Cheng. I can't help but suspect and coerce Tao to blow up the bus and then provide clues to mislead the police. Zhang (surname)

Cheng is not sure whether Xiaohe is really related to the bomb, but he can only ask them to hand over all the electronic equipment on the grounds of assisting in the investigation.

After Xiaohe handed over the electronic equipment, he couldn't help asking Mr. Zhang if he had found out about Tao and whether it was a bomb made by Tao himself. Mr. Zhang saw that Li Shiqing and He Yun were suspicious, so he stayed to talk with them. At this time, I found that their lives did not intersect with Tao and Wang Xingde. Mr. Zhang had to let Ye Qian check He Yun's other mobile phone again.

People from the bus company came to the public security bureau to cooperate with the investigation, recognized Xiaohe and truthfully told the police what they had done before. Xiaohe explained that they only went to the bus company to find a motive for committing the crime. Zhang Cheng is dubious about this statement. On the other hand, traces of chemicals were found in Tao's rented garage and home, as well as her online trading records of chemicals. Du bureau think and small suspicion is not big.

In order to solve the problem, when Mr. Zhang asked questions, he kept asking questions about Wang and wanted to know where the crux of the problem was. Finally, Li Shiqing asked Mr. Zhang if one day he received a message that there was a bomb on the bus and it exploded 20 minutes later, would he call the police? Zhang Cheng explained that no matter what the caller said was true or not, he would not hesitate to call the police. He thinks that if it is true, it can save a car full of people's lives, so he will definitely go to the police.

After Mr. Zhang answered, He Yun Jr. made excessive demands on Mr. Zhang and left Mr. Zhang's mobile phone number. When it was circulated again, He Yun Jr. began to have a nosebleed. He found that his health was getting worse and worse, which forced him to spend time solving the explosion problem.

After cleaning up the nosebleed on his face, He Yun Jr. took photos and sent Zhang Chengfa a message telling Zhang Chengfa about the bomb. After He Yun sent the message, he called Mr. Zhang again to confirm that Mr. Zhang had seen the message, and then he was waiting to implement the next plan.

After seeing the information, Zhang Cheng and Xiao started their plan, trying to delay the time, so that Zhang Cheng had time to monitor and the police could get on the bus along Jiangyan East Road, so they deliberately quarreled in the car on the grounds that they were perverts.

Li Shiqing quarreled with He Yun, Jr., and clamored for Wang Xingde to get off. Wang Xingde had to stop to let Li Shiqing off because time was running out. Seeing that things were going so smoothly, Li Shiqing could only regret not getting off the bus and asked He Yun Jr. to get off, so He Yun Jr. lied that the USB flash drive was missing and wanted to stay and look for it. Seeing that time was running out, Wang Xingde had to close the door and speed up without stopping at Jiangyan East Road Station before the bus got on the bridge. Zhang Cheng couldn't get on the bus, so he had to inform He Yun Jr. to play it by ear. Xiaohe had to sit in front of Tao and wait for the opportunity to control Tao.

After Wang Xingde accelerated, Zhang Cheng and others had to call the police to chase the car and park it on the bridge. Time was running out. Wang Xingde rushed to the bridge in despair, ran into a police car and finally stopped the car.

With the help of passengers, Xiao controlled Tao with a bomb and waited for the police to arrive at the station to solve it, while Wang Xingde was persuaded to accept the fact that Wang had died and wait for the police to investigate, so as to avoid the death of a car full of people.

When the police arrived, He Yun Jr. found that the explosion time was approaching, so he had to break through the window and give the bomb to the police. Zhang Cheng then threw the bomb into the sea. Because the explosion time was too fast, Zhang Cheng was blown to pieces by the bomb before he could throw it away.
