Gu Yiran stayed up all night, conducting a detailed examination of the key evidence in the drug-driving case, and finally confirmed that it was “Xue Angel”.However, Zheng Bei had not yet made a breakthrough in tracing the source of the goods. As soon as he informed Gu Yiran of the situation, he received an emergency move notice.Gu Yiran's decision caught Zheng Bei off guard, but he acted quickly and took his sister and Zhao Xiaoguang to help move to Gu Yiran's new home.The layout of the new home made Zheng Bei suspicious. Daily necessities were all available, and there were traces of habitation on the furniture, as if someone had lived here for a long time.

What was particularly eye-catching was a locked room, which aroused the strong curiosity of Zhao Xiaoguang and Zheng Nan. They tried to find out, but were politely stopped by Gu Yiran.Recalling the sudden change of Gu Yiran's trip to Guangzhou, Zheng Bei began to suspect that Gu Yiran might have other unknown purposes besides assisting in handling the case.He tentatively asked Gu Yiran, but failed to get any substantive reply. Instead, he was politely persuaded by the other party to “ focus on his own life”.

Early the next morning, members of the task force went to the hospital to express condolences to the families of the victims of the drug-driving case. They witnessed the desolate scene of the victim's wife waiting alone, and everyone felt heavy.At the subsequent case analysis meeting, Zheng Bei speculated based on existing clues that the drug gang may have used a large number of lampheads to distribute drugs in large quantities in a short period of time, and acted in an extremely secretive manner, showing a high degree of organization and planning.He believes that the mastermind behind all this, Xiao Ma Ge, planned carefully to take advantage of the opportunity when the police arrested Qin Yihe and destroyed the drug manufacturing factory to quickly complete the handover with “Damp Head”, thereby evading the attack.

Brother Ma's cunningness exceeded Zheng Bei's expectations, making him feel that it was more difficult to catch him.Although Zhao Xiaoguang tried to view the results achieved from a positive perspective, Zheng Bei knew that the drugs sold and the tragedy of the victims could not be undone.With anger and helplessness intertwined, Zheng Bei sat alone in the courtyard and meditated. Gu Yiran appeared at the right time to comfort him and encourage him not to bear too much psychological burden.

At the same time, Ding Guozhu showed great fear when faced with the terrifying face of the drug driver, and was even more ashamed after being teased by his mother.Gu Yiran offered to help Ding Guozhu overcome his timidity, and the relationship between the two became closer.

As night fell, when Gu Yiran was busy sorting out clues about drug dealers, Zheng Nan unexpectedly visited, bringing dinner and help, and asked Gu Yiran to translate the content of the video tape.This sudden interruption made Gu Yiran feel uncomfortable. He quickly asked Zheng Bei for help. Zhao Xiaoguang came after hearing the news and successfully rescued him.Gu Yiran took the opportunity to propose teaching Zhao Xiaoguang Cantonese so that the latter could better communicate with Zheng Nan.

Early the next morning, Gu Yiran taught Zhao Xiaoguang Cantonese in the hospital, and Ding Guozhu brought the good news that the drug driver confessed to “lamphead”.Before leaving, Gu Yiran gave Ding Guozhu a box of ghost story tapes, intending to exercise his courage by listening to ghost stories.

Later, Zheng Bei and Gu Yiran interrogated “Dengtou”. Although they obtained certain information, their gains were limited.The lamp heads insisted that they were only trained and responsible for picking up goods at designated locations, and knew nothing about the up and down lines.Facing the cunning drug trafficker network, Zheng Bei said that no matter how difficult it is, he must thoroughly investigate it.In the dead of night, Xin Tiegang encounters Ding Guozhu in the kitchen who has lost track of time while practicing courage by listening to ghost stories, while Gu Yiran continues to disguise his identity and track Li Wenlong, and the investigation of the case is still in full swing.
