Episode 30 recap: Bai Ming Han met with Snow Wolf.

Captain Chen and his team went to the burning carpentry warehouse to investigate. They found a biscuit barrel with acetylene on top, which caused the fire. Captain Chen noticed that the workshop only had scattered blueprints, and if they wanted the master plan, they would have to go to Chu Gong or Director Han's office. They had already investigated Chu Gong's office and found no issues. Captain Chen recalled that Director Han seemed uneasy when they were at the warehouse, so he went to find him.

Director Han opened the safe and showed them the master plan, assuring them that everything was fine. He mentioned that Master Niu and others had come over earlier to review the blueprints, and they had taken out the master plan. Captain Chen approached Pang Hong Mei and asked her about it. Pang Hong Mei explained that she was chasing after a person at that time, but the person had a mask on, and she couldn't see their face clearly, only a side profile.

Captain Chen discussed the situation with Ji Dan Yang and asked him to analyze the data, hoping he could determine the time delay of the ignition device. Ji Dan Yang calculated that it was approximately five to five and a half hours because they didn't know how much water the enemy had put in. They could only calculate based on the maximum value.

Considering the lengthy period, many people would have passed through the carpentry warehouse. Captain Chen thought having a rough timeframe would be sufficient. Lu Cheng approached Bai Hui, suspecting him of being a spy. He believed that while he was sent to take photos, the carpentry warehouse caught fire. Bai Hui denied being a spy, and Lu Cheng couldn't believe his suspicions.

Unable to bear the psychological pressure, Lu Cheng wanted to turn himself in, thinking that as long as the items hadn't been taken out, they wouldn't have any problems. Bai Hui mentioned that the titanium metal had already been sent to Taiwan, and they couldn't escape the accusation. Bai Hui stated that he had already planned for what comes next. When the time comes, they will go to Hong Kong and live comfortably. For now, Lu Cheng just needs to endure a little longer.

Lu Cheng handed the camera to Bai Hui. Bai Hui saw the secret signal and said that a mission had arrived at the designated location. He took the note and left. Bai Hui pretended to come to the tailor shop to get clothes done and gave the camera to Aunt Miao, who then handed it to Captain Lin when he arrived.

Captain Lin pretended to feel unwell and went to see a doctor with Bai Ming Han. He mentioned that he had exchanged the secret signal with Bai Ming Han several times, but Bai Ming Han refused to rejoin the team. He asked what was going on. Bai Ming Han stated that he only wanted to live a peaceful life, and this place was his home.

Captain Lin brought up Bai Hui, urging Bai Ming Han to think not only for himself but also for his daughter. Bai Ming Han couldn't understand why they insisted on him rejoining the team. Captain Lin explained that they needed Bai Ming Han's medical skills, as only Bai Ming Han could kill Chu Gong.

Bai Ming Han still insisted on seeing Snow Wolf. Captain Lin told him to come to the usual place in the evening and arrange the meeting himself. Pang Hong Mei approached Bai Hui and asked if he had passed by the carpentry warehouse yesterday while delivering medicine. Bai Hui replied that he took a different route and didn't pass by there.

Wu Rui pretended to have a nose injury and came to Bai Hui for examination. Bai Hui informed him that the public security was already investigating the carpentry warehouse incident and advised him not to come unless there was a special situation. Bai Ming Han arrived at the warehouse and unexpectedly encountered Aunt Miao instead of Snow Wolf. Bai Ming Han expressed surprise that someone who used to run errands suddenly became Snow Wolf. Aunt Miao stated that it didn't matter and commanded him as Snow Wolf to complete the mission quickly.

Pang Hong Mei and the others found the owner of the biscuit barrel. At that time, he was drinking with Wu Rui and took out the biscuit barrel.
