The sacrifice of Dr. Gong shocked the comrades of the underground party. There are some patriotic people in China. The comrades of the underground party let Dong Shumei win Tong Jiaru to join the Communist Party. At the Wei Zhongcheng annual meeting, Tong Jiaru fought against the crowd. He has put his own life and death aside and successfully protected Ouyang. Gongjin and the students of the middle school were not harmed, and the comrades of the underground party decided to secretly protect Tong Jiaru.
Tong Jiaru was extremely nervous when Tang Wei was murdered. He asked Shen Tong to notify Ouyang Gongjin as soon as possible. Shen Tong suggested Ouyang Gongjin to meet according to the agreed signal. Ouyang Gongjin found that Shen Tong had been monitored by the Japanese, and he sneaked into Shen Tong's house told Shen Tong to specifically tell Shui Ching to see him when he left the house.
Xu Xian is going to follow Shen Tong to find Ouyang Gongjin, and go to expose the whereabouts of Ouyang Gongjin to the Japanese. Watercress desperately blocks the door and does not want him to expose the eldest lady. Shen Tong treats her like family, and Xu Xian is worried that the Japanese will not let them go. . Shuixian solemnly told Xu Xian that if she insisted on exposing Shen Tong, she would tell Master Feng that she was pregnant. When Xu Xian saw that Shuixian was also threatening him, she lied to her that they would run away together at night.
In the evening, the watercress packed her things and walked with Xu Xian with joy. Unexpectedly, Xu Xian took her to the bridge and carried the five-month-pregnant watercress directly into the river. The cress was fluttering in the river. Fortunately, Ouyang Gongjin drove over. He knocked Xu Xian out and jumped off the bridge to save the cress.
Shen Tong was always being followed by secret agents. Master Feng came forward to take Shen Tong home and finally met Ouyang Gongjin. Tong Jiaru finally saw these two students who made him worry every day. Shen Tong and Ouyang Gongjin hurriedly left Shanghai. If they didn't leave, he wouldn't be able to sleep for a day. Tong Jiaru had already planned to let them escape to Kunming. He persuaded Shen Tong to go to France for further studies, while Ouyang Gongjin continued to study, and they would come back to serve the motherland when the new China was established. Ouyang Gongjin understood the good intentions of the master and Shen Tong. He was still waiting for the task given to him by his superiors, and he was ready to die in the line of duty.
Tong Jiaru was worried that Ouyang Gongjin would not leave Shanghai. He had asked Feng Ye to send him a few people in advance. When Ouyang Gongjin did not leave, he would have to be kidnapped by him. There was no mistake in Tong Jiaru's plan, but Ouyang Gongjin had already discovered that he was being followed and punctured Feng Ye's tire in advance. Tong Jiaru shed two tears in distress, and after all, he could not get rid of his beloved apprentice. Ouyang Gongjin solemnly confessed to Shen Tong that once the Japanese were driven out of China, he would come back to pursue Shen Tong again.
Ouyang Gongjin had found the person who betrayed Jiang Liming. Tong Jiaru stood in front of Ouyang Gongjin's gun. After finding out that the person in the sack was Xu Xian, he resolutely refused to let Shen Tong and Ouyang Gongjin kill Xu Xian. In Tong Jiaru's eyes, everyone is his student, no matter what mistakes they make, they can't kill each other. After Xu Xian was rescued by Tong Jiaru, he ran away quickly.
Toshiro Higashimura was arrested by the people in the Shanghai Concession, and the Japanese upper class felt it was shameful. He severely criticized Toshiro Higashimura and asked him to get rid of Ouyang Gongjin as soon as possible. The Japanese have already obtained the information, and Chongqing has already launched a plan K. Perhaps Ouyang Gongjin will soon get the K plan. At this time, Ouyang Gongjin really received the task given by the organization, and he was ordered to contact an important person in Chongqing. Ouyang Gongjin agreed without hesitation. He came to the meeting place on the note. Although he used a secret code, he soon discovered that there were Japanese agents inside. Ouyang Gongjin quickly retreated, and soon he was knocked out by several unknown people and taken away.
