Episode 2 recap: Shen Qiu Ping assassinated Coach Jin.

Instructor Miao publicly praised Fang Li and criticized Chen Ke Hai. The others congratulated Fang Li, but Chen Ke Hai didn't seem to be bothered by the matter. Instructor Miao expressed surprise at Chen Ke Hai's final shot and invited Chen Bin to participate in the mission, believing that Chen Ke Hai wouldn't disappoint him. Chen Bin went to the lakeside alone, intending to burn a photo, but Chen Ke Hai snatched it away. At that moment, Chen Bin revealed his Kuomintang identity, stating that all his comrades in the photo had sacrificed themselves, and he was the coward who had survived by hiding in a corner. He was waiting for Chen Ke Hai to expose him. Chen Ke Hai returned the broken glasses to Chen Bin and advised him to train well. As Chen Ke Hai left, Fang Li continued to secretly observe them from the shadows.

Instructor Miao distributed the information to everyone, and each person had a different task, working together with their assigned roles. Chen Bin disguised himself as a businessman, while Shen Qiu Ping posed as a student. When Chen Bin tried to shoot at the target, he realized that his pistol had no bullets, immediately exposing himself and engaging in a fierce gunfight with the enemy. Shen Qiu Ping narrowly avoided being shot thanks to Coach Jin's intervention, but she pointed her gun at him. Chen Bin used a dagger to kill the target, but Chen Ke Hai stopped Shen Qiu Ping's actions, and she slowly lowered her gun. After the operation, they returned to the military camp, and Chen Bin was tied up. Sun Da Chuan interrogated him to determine which unit he belonged to, noting that his assassination technique was not that of a novice and was clean and efficient. Coach Jin used a wooden stick to pierce Chen Bin's major artery, and Chen Bin voluntarily confessed that he was a deserter from the Battle of Shanghai. He had come here to earn a subsidy and open a clinic back home. Instructor Miao warned him that from now on, it would be a matter of life and death between them. When Chen Bin returned to the dormitory injured, he discovered that Chen Ke Hai was not there and suspected that he was a spy.

Today's assignment is for male and female trainees to write down the name of someone of the opposite sex whom they must make fall in love with them within a week. This is a skill that spies must master. Chen Ke Hai and Fang Li made a bet on who Shen Qiuping would write the name of. Shen Qiuping appeared in front of Coach Jin dressed provocatively to express her gratitude for saving her life. Chen Ke Hai followed Shen Qiuping to the classroom, where she took off her coat and approached Coach Jin to ask for guidance on marksmanship. She had Coach Jin's gun in her hand and was about to shoot when Chen Ke Hai interrupted her. Coach Jin saw through Chen Ke Hai's tracking of Shen Qiuping, and Shen Qiuping slapped him. In the training field, he directly asked her if she was here tonight to assassinate Coach Jin because she had attempted to assassinate him before. If she fired tonight, she would also lose her life. Although she had aimed the gun at Coach Jin last time, she didn't notice the dagger in his left hand, which was also aimed at her. It was even more dangerous just now when Coach Jin took the gun from her. He realized that the gun was never loaded with bullets, and he claimed that everyone should be cautious of those around them. He had weighed the gun when he snatched it from her. Her mother hoped that she would stay alive because Chen Ke Hai remembered her mother's appearance from her pocket watch and investigated her family background, discovering that her parents were killed by Coach Jin.

Chen Ke Hai watched Shen Qiuping crying and gently put her coat on her. She thanked Chen Ke Hai for saving her this time and decided to wait until she became capable before assassinating Coach Jin. Shen Qiuping had already planned an escape route in case the assassination failed, using glass shards hidden in her shoes. Fang Li, who was hiding in the shadows, saw his beloved with Chen Ke Hai and felt heartbroken, so he drowned his sorrows in alcohol. Chen Ke Hai informed Shen Qiuping about the search for the mole because that was the reason he had been following her. Only Shen Qiuping knew about it, and when they locked eyes, an obvious subtle affection arose between them as they silently gazed at the sky.

Fang Li, who was drunk, returned to the dormitory and continued drinking with his roommates. Chen Ke Hai escorted Shen Qiuping back to the dormitory, and at that moment, Fang Li approached them and directly grabbed their hands, urging them to hold hands. Yang Zhen Zhen wanted to leave the training camp, but she couldn't disclose her whereabouts. The teacher gave her a hairpin to use as a cover. Chen Ke Hai quietly went to the transport team and mentioned that he could only bring one person next Wednesday. The driver agreed to help him because he wanted to earn some extra money and said that Fang Li was fortunate to have Chen Ke Hai as his friend. Fang Li secretly discovered Chen Ke Hai's deal with the driver but didn't alarm Chen Ke Hai. In the night, Chen Ke Hai took Fang Li to the kitchen secretly, where he brought out a cake and Shen Qiuping brought out longevity noodles to celebrate Fang Li's birthday.
