Gao Tianyang sneaked into Jiahui's mysterious attic and found several wigs and various makeup tools, as well as a box of smoking cessation candy, which was the type that Huang Jiaming often ate. Gao Tianyang became alert.Through the secret listening equipment installed in the attic, Gao Tianyang learned that Jiahui was going to the port market at 5:30 to meet a man named Basong.Gao Tianyang immediately deployed actions to track Jiahui.Unexpectedly, during the arrest process, Yewu's informant lurked on the roof of a nearby building and discovered traces of the National Security personnel. The National Security Bureau had to implement the arrest operation in advance.Jiahui once again threatened Gao Tianyang. In order to confuse Ye Wu, Gao Tianyang decided to take a long-term approach to catch the big fish, allowing Jiahui to destroy the samples and escape from the market. In the end, the national security only arrested Basong, the contactor.Bassong's surface identity is a sailor, codenamed “Carman”, but he is only responsible for transporting intelligence and has no understanding of the situation in Jinhai.Gao Tianyang discovered that the transparent liquid Jiahui destroyed was a biological experimental sample, which meant that, as he expected, there was an unknown spy in the biological group.Gao Tianyang warned Jiahui not to cause trouble for him again.Jiahui didn't take it seriously, but asked him why this operation would be followed by the National Security Bureau.Gao Tianyang informed that Basong had been targeted by the National Security Bureau. Jiahui was doubtful. The two faced tit-for-tat and broke up unhappy.
