Lin Kanshan sat in the car and told Lu Zhifei insinuatingly that some internal documents were like antiques and could be exchanged for money.Lu Zhifei thought of his boss's recent abnormality and gradually realized that this business was not just about investing in setting up a factory.On the National Security side, Cao Xiaoou was brought in to cooperate with the investigation, and He Chunxiao was preparing to participate in the interrogation under the guidance of his master.

Ma Qi first asked He Chunxiao to simulate the scene, pointed out that his questions were too blunt, and also reminded him that it was crucial to make a breakthrough in time in the early stage.When he actually faced Cao Xiaoou, He Chunxiao followed the steps he had prepared, but the other party always responded with “don't know”“can't remember”.Ma Qi took over the conversation and repeatedly asked about his uncle and nephew's dealings and items stored on behalf of him, refusing to let him get around easily.

After Chen Leyuan returned to Taipei, he handed the action report to Zhu Yingjia and conducted self-examination first.However, Zhu Yingjia reminded him that the report should not only write about what he had done wrong, but also emphasize the complexity of the situation, on-site changes, and difficulties in response.Chen Leyuan understood that his boss intended to excuse himself and revised the report again.Zhu Yingjia then went to see Zheng Guiping and took advantage of Cao Liaoping's arrest to suggest that someone within the military intelligence department might have leaked secrets and asked for investigative authority.

Li Fengge continued to search Cao's house and found a whole box of tapes.After continuous questioning, Cao Xiaoou finally said that his uncle often encouraged him to go overseas for inspections and gave him a kraft paper portfolio to keep for him.This clue led Guoan to the real intelligence hidden by Cao Liaoping.

Cao Liaoping remained silent, did not eat and drank only a small amount of water.He Chunxiao tried to analyze his psychology, played the confidential contents of the seized tapes in person, and clearly pointed out the consequences of leaking the secrets, but still could not get him to speak.The investigation room next door continued to advance, and when it came to Cao Liaoping himself, the case came to a halt again.

Guoan asked Jia Chunlin to learn about the situation, and he volunteered to testify and report Cao Liaoping.He Chunxiao was frustrated because there was no progress in the interrogation, but Ma Qi remembered that it was his apprentice's birthday and specially added an egg to the instant noodles.In the midst of their busy schedule, this became a very brief birthday meal for the two of them.

Wei Guangjin led people to check the Cao family's old house, and Ma Qi found medicine in the drawer and cash in the flower pot.He put these findings together with the relationship between his uncle and nephew, and gradually found what Cao Liaoping cared about most.At the same time, Jin Lina accompanied Lin Kanshan to visit the factory. Lin Kanshan once again urged her to change to a house and was willing to pay for half a year at a time.

Ma Qi sat down in front of Cao Lioping again, and instead of just asking about missile information, he mentioned that he had no children and regarded his nephew who he had brought up as his own.Although Zhu Yingjia promised to provide imported drugs, these promises would be meaningless if Cao Xiaoou was unable to go abroad.When it came to his nephew's future, Cao Liaoping finally showed a different reaction than before.
