Under the protection of Pang Hongmei, Ji Danyang successfully evaded the interception set by the Kuomintang in Hong Kong and successfully returned to the embrace of the motherland. Immediately, he set off for Lumen, preparing to launch the "Water Drop Project". However, the Kuomintang did not give up because of the defeat in Hong Kong, but continued to deploy an operation called "Project Rock" in Lumen in an attempt to sabotage our scientific mission.
"Snow Wolf" is the top person in charge of the "Rock Project" in Lumen, a senior spy. Although the "Snow Wolf" had been lurking in Lumen for a long time, it was not awakened until after the failure of the Kuomintang interception and killing, and it has not taken action. However, three details revealed in the play reveal that Bai Hui's father, Bai Minghan, is the "snow wolf".
First of all, Bai Hui's biological mother was the secretary of the Kuomintang Arsenal, and Bai Hui's father sacrificed his life for the country. Bai Minghan is not his biological father to Bai Hui, but an adopted orphan. This aroused Pang Hongmei's suspicion that Bai Minghan had a deep relationship with the Kuomintang.
Secondly, Bai Hui can actually understand English. This was especially evident when Ji Danyang first arrived in Lumen. Bai Hui is a small ** in Lumen, and for an ordinary person who has not received a higher English education, it is obviously unusual for her to know English. This aroused Pang Hongmei's suspicions, thinking that this might be one of the clues that Bai Minghan was a snow wolf.
Finally, Bai Minghan collected intelligence and passed on information through home visits. He often consults the crowd in the instrument factory and obtains information through conversations with them. This made Pang Hongmei firmly believe that Bai Minghan was the "snow wolf".
This series of discoveries made Pang Hongmei doubt Bai Minghan's true identity and realized that he was a Kuomintang spy. Bai Hui didn't know it, and was suspicious of Bai Minghan, who he regarded as his own father.
