Lele followed Wu Yu until he entered a magnificent nightclub and had a drink with Feng Lun in a box.Fenglun was notorious for engaging in illegal human trafficking and had a long-standing rift with Wei Dongshan, which made Lele worried about Wu Yu's relationship with Fenglun.However, Wu Yu in turn comforted Lele, asking her to relax and return first.

At the same time, Wei Dongshan's men reported to him that Wu Yu frequently entered the mountainous area alone. They speculated that Wu Yu might be secretly transporting people for Fenglun and seeking personal gain from it.Lele overheard these conversations, but when Wei Dongshan asked her for confirmation, she chose to keep Wu Yu's secret.Later, Wu Yu took Wei Dongshan to find Feng Lun, and met the powerful Wen Ge through Feng Lun's introduction.

One group was responsible for monitoring the dynamics of the base station, while the other group went to the location of the base station for on-site investigation.However, when they arrived at the Xixiaguan base station, they found that the base station towered into the clouds and required an elevator to reach it.Zhou Jia decided without hesitation to climb the base station transmission tower herself and found a key piece of hardware inside the base station.Despite their best efforts, the foreign group managed to breach the server at the last moment.

Hu Xiafeng agreed with Guo Weijie's suspicion and immediately ordered the task force to stop all contact with the outside world, and at the same time implemented a strict information blockade on the 901 office.They withdrew their overt investigators, replaced them with undercover agents, and conducted in-depth background checks on everyone who was in the building at the time.Guo Weijie realized that his impulse had caused harm to Zhou Jia, so he personally prepared a cup of coffee for her to apologize.The two finally settled their differences and reconciled.
