After the drunk driving incident, Lin Kanshan became suspicious of He Chunxiao's identity.He first urged Jin Lina to help change her residence, and then pretended to be a police officer and called Li Huadong's cover unit to verify his whereabouts.Guoan had already prepared an explanation. The person who answered the phone confirmed that Li Huadong was hospitalized after a fight with He Chunxiao, so there was no flaw in this test.
He Chunxiao officially moved into Jinlan's house, and the two used their passionate love and cohabitation as a cover to take turns monitoring the neighbors.In order not to make mistakes in the details of life, they explained their habits and preferences to each other, rearranged the room, and practiced the movements of a couple to get along.He Chunxiao was always a little reserved, so Jinlan simply reminded him to get used to being close to her. He mustered up the courage to kiss her cheek gently.

He Chunxiao looked through the monitoring records and found that when Lin Kanshan was at home, the alarm clock would always sound at a fixed time.Jinlan also noticed it and guessed that was the time when the other party wore headphones to receive instructions.The two wrote down this rule, hoping to find further breakthroughs.
In the research institute, Jia Chunlin entered the data room in the middle of the night and found that the formula in the confidential document was exactly the same as what Cao Liaoping had copied on the paper.The next day, he saw the notice for the academic conference in Hong Kong on Cao Liaoping's desk. He checked the tea and the tape recorder, but found no other abnormalities.When Cao Liaoping arrived at the unit, he noticed that the guard had changed, and he felt increasingly uneasy.When Jia Chunlin saw him entering the room, he stood up and left, leaving a smile of unknown meaning.
Jia Chunlin wanted to report Cao Liaoping to Mr. Jiao, but when he arrived at the office, he found Cao Liaoping inside, so he had to change his words and leave.Cao Liaoping saw what he had mastered, and he broke into a cold sweat behind his back.The original conflicts between the two sides have become more and more suspicious of each other.
Lin Kanshan decided to go to Jinlan's house to take a look in person.After entering the door, he paid attention to the equipment in the room, and deliberately broke the cup to observe the reaction of the two people.Jinlan and He Chunxiao suppressed their nervousness and responded like ordinary couples.Cao Liaoping sent a message through the pager at this time, and Lin Kanshan found a reason to leave.After they left, the two went through the trash he threw out, but still found no substantial evidence, and only learned more about his daily routine.
Cao Liaoping's physical examination revealed liver damage, and he suspected that Jia Chunlin had poisoned him.He took the initiative to invite old colleagues to dinner and recalled the days when they worked together, hoping to suppress the conflict.Jia Chunlin did not want to go along with it, saying bluntly that he would never betray his motherland.Cao Liaoping repeatedly defended his innocence, but the other party did not believe him at all.

The meal failed to smooth things over.Jia Chunlin emphasized that personal friendship should not override national interests, then smashed the bottle and left angrily.Cao Liaoping suddenly thought of the danger and hurriedly chased him out to call him. At that moment, a plaque fell in front of Jia Chunlin.If he took another step forward, he might be hit.Jia Chunlin was shocked, looked back at Cao Liaoping, and ran away quickly.
