In the early morning, Gu Yiran heard Zheng Bei muttering to himself in his sleep, repeating the words “乐乐” until the morning light faded.Gu Yiran arrived at the task force ahead of time, carefully cleaned up the task team's place, and prepared a huge blackboard.Zhang Xueyao and others smacked their tongues when they saw this, and were not too repelled by Gu Yiran.

At present, the task force has pinpointed the whereabouts of the murderer in Haran City. The beast boarded the train on the 31st and arrived in Haran on the 2nd. During this period, the uneven distribution of the spoils may have led to the death of the two brothers Song Wen and Song Wu.When Zheng Bei reviewed the employee information of the glass factory, he discovered a key omission: Jiang Xiaohai, the reporter, was not the security guard on the night shift that night. The real person on duty should be Song Wu.

This is enough to show that the Song brothers deliberately chose this day to conduct secret transactions in the empty white building to avoid outside attention and suspicion.In addition, Zheng Bei further investigated and found that Jiang Xiaohai had a criminal record. In the 1990s, he was imprisoned for more than five years for causing serious injuries in a fight in the south. This discovery intensified his suspicion of Jiang Xiaohai.

It happened that Ding Guozhu collected evidence from the crime scene and inferred the presence of a fourth person at the scene through shoe print analysis.Based on this, the task force re-examined Jiang Xiaohai and officially listed him as one of the suspects.Facing the interrogation, Jiang Xiaohai tried his best to defend himself, claiming that he concealed part of the situation because he was worried about being mistaken for the murderer. He recounted the incident in detail, claiming that he originally tried to rescue Song Wen but failed to prevent him from falling from the building.

Zhang Xueyao and Ding Guozhu visited the surrounding glass factory and successfully found witnesses.The witness confirmed that on the night of the incident, he witnessed Jiang Xiaohai struggling to hold Song Wen who was about to fall for a long time, which was consistent with Jiang Xiaohai's confession.In view of the fact that Jiang Xiaohai was timid and did not report the crime in time, but his behavior and confession pointed to him as not the murderer, the task force finally ruled out his murder suspicion.

The task force's only clue to the murderer is that he is from eastern Guangdong, has a distinct eastern Guangdong accent, and is about 20 years old.After Zheng Bei learned the location of the canteen, he immediately arranged for Ding Guozhu to check the fingerprints on the phone.After careful comparison by Ding Guozhu, it was finally confirmed that the man who made the call was the man from eastern Guangdong who committed the crime.

Zheng Bei then deployed members of the task force to conduct a comprehensive investigation around the canteen, and personally took Gu Yiran to change clothes and sneak into the ballroom so that he could better integrate into the environment for observation.During the investigation, Zheng Bei accidentally learned key information through his informant Mouse: Recently, a new face was secretly selling “Red Dragon” (referring to a certain banned drug).

At this time, Guangdong Tsai was hiding in the dressing room of the ballroom to conduct transactions, passed by the rat, and then hurriedly left and took a taxi.The driver Brother Hou drove A Liang, a boy from East Guangdong, to the abandoned taxi factory in Yifeng. According to the instructions of the boss Er Jin Ge, he teamed up with other accomplices to try to kill A Liang.However, A Liang had extraordinary skills and escaped in full view of the public. Brother Monkey had to report the matter to Brother Er Jin.Brother Er Jin was furious after hearing the news and strictly ordered his men to get rid of A Liang before the police found him.

That night, A Liang secretly traded in an abandoned residential building, carrying a pistol with him, and took a rest in an abandoned room between transactions.Early the next morning, Zheng Bei received urgent intelligence that there were suspicious outsiders near the residential building, so he immediately drove there and successfully found a hidden doorway leading into the building by asking the stall owner.

After entering the building, Zheng Bei encountered two men fighting fiercely over the drugs. The scene was very chaotic.One of the men saw that the situation was not going well and tried to escape crazily.Zheng Bei reacted quickly and gave chase.The man frantically took a little girl hostage, making the situation even more critical.

At the critical moment, Jiang Xiaohai suddenly rushed out. Regardless of his personal safety, he slammed into the man, successfully knocked him away, and picked up the little girl Maomao without hesitation.On the other hand, Zheng Bei quickly stepped forward, subdued the man who had lost the ability to resist and pinned him to the ground, successfully averting the danger.
