Episode 37 recap: Bai Hui took Ji Dan Yang away.

Bai Hui called Ji Dan Yang and informed him that He Xi Wen had a problem. Ji Dan Yang hurriedly came over and asked Bai Hui what the problem was with He Xi Wen. Bai Hui explained that there was no issue with He Xi Wen and that he wanted to be with Ji Dan Yang.Earlier, Ge Yun gave Bai Hui a bottle of a drug that can cause unconsciousness. Bai Hui used it on Ji Dan Yang, causing him to become unconscious and taking him away. Pang Hong Mei and Lao Jiang were studying the musical staff here and discovered the corresponding relationship between the staff and a code. They translated several chapters of the musical staff they had found earlier and understood the actions they had taken here. They also figured out that Wu Rui is a code name for a person.

Bai Hui is known as Fei Hu (Flying Fox). Lu Cheng's involvement in this matter is relatively simple, likely being manipulated by Bai Hui. Captain Chen and his team found something suspicious with Chu Huai Qiu and rushed to investigate, only to discover that the camera had been replaced with a different one. Pang Hong Mei remembered seeing Li Qiu Chen with a camera before, so it's highly possible that it has been switched.

Chu Huai Qiu is extremely anxious. Since the blueprints couldn't be conveniently carried, they were all photographed and stored in this camera, representing all their hard work. Director Zhang reassured Chu Huai Qiu that the data has been backed up and they can bring it to Beijing tomorrow. The information is guaranteed not to leak out of Lumen.

Bai Hui pretended to be seriously ill, and Zhang Ling drove him out. Unexpectedly, Bai Hui killed Zhang Ling on the way, claiming that he had seen too many things he shouldn't have. Captain Chen and his team arrived at the hospital to capture Bai Hui but found that he was no longer there. Director Zhang instructed Pang Hong Mei and others to go to Bai Ming Han's house and immediately arrest Bai Hui if they encounter him.

Pang Hong Mei and the others found a box at Bai Ming Han's house. Inside the box were Bai Ming Han's identification documents, confirming that he was indeed a spy. However, there was also a letter written by Pang Hong Mei's father, which was a plea for help from before. Pang Hong Mei realized that the situation was not as simple as it seemed. Director Zhang mentioned the letter and explained that Pang Hong Mei's father had recruited Bai Ming Han, but because Pang Hong Mei's father was exposed, the Snow Wolf organization took action prematurely, resulting in his father's sacrifice. The letter became unnecessary and was never sent out.

Currently, the information and Ji Dan Yang are in Bai Hui's hands. They quickly pursued them, and Bai Ming Han arrived at San Tiao Xia. They asked Bai Hui what was going on, and Bai Hui expressed the desire to take Bai Ming Han to Taiwan for a peaceful life.

Bai Ming Han was also deeply saddened and surprised that Bai Hui had taken this path. Bai Hui mentioned the Southern Mountain Youth Class, and Bai Ming Han then learned that Bai Hui had spent four years there. Bai Hui believed that Kou Xue Song had saved his life and wanted to repay him. However, Bai Ming Han revealed that Bai Hui's biological parents were actually killed because they refused to comply with a non-resistance policy, contradicting what Kou Xue Song had claimed about them being killed by the Communist Party.

Bai Hui felt that the truth no longer mattered. After all the things they had done, there was no turning back. Ji Dan Yang was also shocked and disappointed, as he never expected Bai Hui to have this kind of identity. Despite the trust everyone had placed in her, she had betrayed that trust. Bai Hui stated that both Bai Ming Han and Ji Dan Yang were extremely important to her, and she intended to take them to Taiwan.

Captain Lin and his team also arrived and entered the cave where Mu Sen was already waiting. Mu Sen was sent by Kou Xue Song to assist Captain Lin and guide them out of Yunnan province. Director Zhang and the others had also realized Bai Hui's intentions. If they crossed the border, it would be even harder to pursue them. Therefore, they must not let them leave the country. Local militias were organized to search the mountains in order to locate them as soon as possible.
