Because old friends were killed one after another, Tong Jiangnan felt very sad and was very angry at the Kuomintang's cruelty.Cousin Han Yurong persuaded Tong Jiangnan to stay away from right and wrong, but Tong Jiangnan believed that only a country has a family, not to mention that Tu Zhe and Li Ruchen died for them.At this time, Tong Sheng came back from outside and was obviously in a bad mood. Han Yurong revealed to Tong Jiangnan that Tong Sheng would most likely get in touch with Su Xing.Later, Han Yurong came to the room to care about Tong Sheng, reminding her that she should consider her marriage as soon as possible, and believed that Zhang Shaomu was a good young man worthy of trust.In Han Yurong's view, married life is just daily necessities, and it is unrealistic to talk about love alone. However, Tong Sheng obviously had no idea about Zhang Shaomu, so he sent Han Yurong away on the pretext that he would have to do an experiment tomorrow.The next day, after Tong Jiangnan and others attended Li Ruchen's memorial service, they came back to discuss countermeasures.

Some people suggested going north directly by land, but Tong Jiangnan thought of Tu Zhe's reminder before his death and told everyone not to take this method, otherwise it would be difficult to ensure safety.Outside the Tong family villa, Wang Dalong came to a stall, contacted comrades from the underground party to learn about the information, and told him to report it immediately if there was any news.Later, Tong Jiangnan came to the laboratory and reprimanded Zhang Shaomu for not telling Han Yurong about Su Xing. Su Xing had to lie and claim that he accidentally let the matter slip.For this reason, Tong Jiangnan found Tong Sheng and believed that Su Xing's current identity was unclear. Regardless of whether his true identity was the Kuomintang or the Kuomintang, the two of them tried to reduce contact as much as possible.After Tong Jiangnan left, Tong Sheng sat alone in the yard in a daze. What Su Xing had said came to mind, and she felt confused.Zhang Shaomu paid attention to Tong Sheng's every move and wanted to comfort her, but was stopped by Chen Xuewei on the grounds of checking the experimental results.In the office, Chen Xuewei discovered that Tong Sheng was backing up experimental data, but Tong Sheng did not admit it.Unable to confirm Su Xing's identity, Tong Jiangnan called the Guanghua Hotel where he was staying and decided to hold a family dinner to invite him for further observation.Since Su Xing's many visits to Tong's house attracted the attention of the spies, Zhou Yaming reminded him to pay attention to safety.

Faced with Zhou Yaming's concerns, Wang Dalong said that according to the old rules, Su Xing would be responsible for meeting Tong Jiangnan, and he would be responsible for responding to and protecting his safety.Dang Xunqi received a secret report that Su Xing went to Tong's house, and Luo Guanying happened to be nearby. He decided to go to Tong's house to meet Su Xing, threatening to make him lose everything in Tong's house.Tong Jiangnan asked Su Xing about the situation in the mainland and the relationship between him and Tu Zhe. Su Xing knew everything and answered truthfully that he and Tu Zhe had never met in person, and they had only maintained contact through special means before.Just as Tong Jiangnan and Su Xing were seated at the table, Luo Guanying suddenly came uninvited.At the dinner table, Luo Guanying first deliberately revealed that he had met Su Xing within the Kuomintang, and then made it clear that he was the one.

During the verbal exchange between the two, Su Xing still did not reveal his identity and had reservations. He even asked him questions, but Luo Guanying refused to answer on the grounds of confidentiality.After three rounds of drinking, Su Xing was about to leave. Before leaving, he reminded Tong Jiangnan that both the Kuomintang and the British government were eyeing him. As long as he didn't make a decision, no one could do anything to him. If he didn't pay attention, it was best to wait., I believe everything will come to light.

Tong Sheng took advantage of sending Su Xing out to ask about his true identity again. Su Xing showed his identity and intentions, which made Tong Sheng trust him more.However, Dang Xunqi learned that Su Xing had left the Tong family and ordered Wu Yanan to lead people to kill him.On the other side, Luo Guanying deliberately fabricated the rumor that Su Xing was a KMT agent in an attempt to convince Tong Jiangnan. Tong Jiangnan was hesitant about this, but Han Yurong was worried, worried that something would happen to Tong Jiangnan.
