Episode 7 recap: Tong Sheng discovered his mother's murderer in the hospital.

After the explosion incident, Su Xing rushed to the hospital to find his teacher Tong Jiang Nan, and told him that Luo Guanying was a Kuomintang spy, warning him not to trust this person. However, Tong Jiang Nan had already firmly believed that Luo Guanying was a member of the Communist Party, because of Luo's daring act of risking his life to save him. In turn, he scolded Su Xing for being prejudiced.

As a result, the trust that Su Xing had painstakingly built with Tong Jiang Nan collapsed again. He went back to the liaison station and told Zhou Yaming about this, never imagining that a single explosion could change Tong Jiang Nan's mind so completely. Li Wenbo came to the hospital to check on Luo Guanying's condition and found that he still had not regained consciousness, even though the nurse indicated that he should have woken up given his condition.

Su Xing hurried to the hospital to warn the teacher not to believe Luo Guanying, because the man was a Kuomintang spy implementing a ruse. But the problem was that Tong Jiang Nan chose to believe Luo Guanying, and even found Su Xing suspicious, no longer willing to communicate with him. Wang Dalong watched this scene anxiously, realizing that they were unable to make Tong Jiang Nan believe them, and the trust they had built up had collapsed again.

Since Luo Guanying had suffered a head injury, he was still in a coma, but his life was not in danger. Li Wenbo asked everyone to leave first and arranged for the police to guard the ward. Wu Yanan reported the situation to Dang Xunqi, wanting to take the opportunity to kill Luo Guanying, but Dang Xunqi felt that the police were still at the hospital, so they should not act rashly.

Tong Sheng hurried home after hearing the news, and learned from his father about Luo Guanying's act of risking his life to save him. After this incident, Tong Jiang Nan was convinced that Luo Guanying was a member of the Communist Party, and as for Su Xing's identity, it was now obvious that he might even have been the one to plant the explosives, no longer the person they had known before.

Li Wenbo found that Luo Guanying had not yet regained consciousness, and asked the nurse about the reason, but the nurse could not explain it. Hearing the nurse's words, Li Wenbo sneered coldly and directly left the ward, and as soon as he left, Luo Guanying's eyelids fluttered, continuing to pretend to be unconscious.

To thank Luo Guanying, Tong Sheng personally went to the hospital to bring him chicken soup. However, when he arrived at the hospital, he recognized Dang Xunqi, the murderer who had shot his mother years ago, on the ground floor. By the time Tong Sheng reacted, Dang Xunqi had disappeared without a trace. Tong Sheng had to calm himself down and go upstairs to visit Luo Guanying.

In the hospital ward, Tong Sheng conveyed his father's intention, indicating that they were ready to head north at any time. Luo Guanying then told Tong Sheng to be careful of Su Xing, as the explosion incident was entirely plotted by Su Xing.

On the other side, Zhou Yaming and the others analyzed the enemy's plan, believing that the top priority was to control Luo Guanying. This would not only prove Su Xing's identity, but also remove a thorn in the Kuomintang's side.

At this time, the intelligence station reported that there was only one police officer guarding Luo Guanying in the hospital, and Su Xing and Wang Dalong were preparing to go to the hospital at night. Shortly after Tong Sheng left, Wu Yanan, disguised as a nurse, took Luo Guanying away without the police noticing. By the time Su Xing's group hurriedly arrived at the hospital, Luo Guanying had already escaped. However, Su Xing discovered their traces behind the hospital, and Wu Yanan turned back and shot at him, then took Luo Guanying away in the chaos.

Luo Guanying angrily questioned Dang Xunqi, wondering why the explosion time was moved up by five minutes from the original 10 o'clock. Dang Xunqi defended himself, claiming complete ignorance, and even offered to prove his innocence with his own life, gradually gaining Luo Guanying's trust. After discussion, the two reached a consensus: first, they must eliminate Su Xing, and then send the democratic activists away at the same time.

That night, Tong Sheng returned home, vividly remembering the scene of his mother being shot. He took a gun from the bottom of a cabinet, swearing to avenge his mother. Su Xing suspected that the enemy would take Tong Jiangnan away from Hong Kong by water, so he continued to contact Tong Jiangnan, trying to regain his trust, while also having people closely monitor all ships and piers in Hong Kong to find the place Luo Guanying had arranged, not wanting to give them any opportunity.

Wu Yanan went to Fatty's hiding place and told him to find a way to kill Su Xing, promising to send him to Vietnam to avoid trouble. Tong Sheng went to the police station to ask Inspector Cha Liangjie for information about Dang Xunqi, but the lack of clues made it difficult to find the person for the time being. Cha Liangjie promised to help her locate the target.

Tong Sheng unexpectedly learned that Luo Guanying had been kidnapped, and hurriedly went to see Su Xing, scolding him to keep away from the Tong family and not to do any more unscrupulous things. Su Xing emphasized that he had never intended to harm anyone, and that the real Kuomintang agent was Luo Guanying, but Tong Sheng did not believe Su Xing's words at all.

As Tong Sheng was about to leave, Su Xing chased after her. In a fit of anger, Tong Sheng pulled a gun from her bag and pointed it at Su Xing, warning him not to take another step forward, or she would shoot.
