Ye Runming wanted to join the GCD, not only him, but also five other classmates. Guo Tielin reminded him that everyone has only one life, and I hope Ye Runming can think clearly. Ye Runming stated that he is willing to exchange his life for the happiness of most people. The day after the conversation ended, Ye Runming solemnly wrote down his application for joining the party. He handed the application to Pei Yuanzhi and asked Pei Yuanzhi to be his party introduction. Li Guoyan and Xu Shaomin also hoped that Pei Yuanzhi could be their party admission The introducer, Pei Yuanzhi, was extremely happy. With Fang Yuerong's consent, Pei Yuanzhi and Ye Runming planned to transport the textbooks to Mengzi, and then went to Wuhan to help transport books and instruments. Although this trip was dangerous, they didn't care.
Bi Yunxiao gave physics classes to everyone, and taught them interesting knowledge of physical refraction and dispersion. Everyone felt that Bi Yunxiao knew a lot. When Ye Runming and Pei Yuanzhi returned to Mengzi, Cheng Jiashu couldn't help but drag Ye Runming to another courtyard and beat him. Cheng Jiashu already knew that Ye Runming was going to Yan'an, and he complained for Lin Huajun. Lin Huajun, Ye Runqing and Bi Yunxiao came to stop Cheng Jiashu, Lin Huajun said that he had broken up with Ye Runming. After Ye Runqing asked his brother for confirmation, he left sadly. Cheng Jiashu was stunned, not knowing what to say. Ye Runming was not angry. His vision and pattern were much larger than Cheng Jiashu's. He did not focus on personal gains and losses, love and hatred, but cared about the current situation of the country.
Bi Yunxiao was about to return to Kunming, but Ye Runqing obviously didn't care about his going or staying. In the dormitory, Bi Yunxiao couldn't understand why the relationship between the five of them was so good when they were in Beiping, but why they became like this now. Cheng Jiashu was wronged this time and was speechless. Ye Runming told his sister that after returning from his trip to Wuhan to transport books and instruments, he set off for Yan'an. Yan'an has the spirit and belief he has been looking for. Ye Runqing didn't think much about it, she wanted to go with Ye Runming, but Ye Runming asked her to stay in Mengzi to finish her studies. Lin Huajun and Ye Runming were talking by the lake, and they had long been relieved of their relationship. They are each other's most important friends, and the years they have spent with each other have been wonderful. When we meet again next time, we will be full of smiles.
Cheng Jiashu met Ye Runming at the station. He was going back to Beiping, but when he heard that Ye Runming was going to Wuhan to help, he temporarily decided to go to Wuhan with him to help. Ye Runming graduated, Cheng Jiashu also asked for leave, and the night school suddenly lost two teachers. Lin Huajun planned to take the class for the two of them. Wen Jie knew that she was tired and took the initiative to undertake part of the teaching work. After Cheng Jiashu and Ye Runming went north to Wuhan, Lin Huajun received a letter from Cheng Jiawen, and learned the sad news of her mother's death, along with Lin's mother's last letter. At the end of her life, Lin's mother thought about many things. She saw the photo of Lin Huajun and Ye Runming, and found that her daughter was not happy, and she would no longer force Lin Huajun to live according to her ideas.
Zheng Tianting told Lin Huajun that after the end of this semester, the Grammar School will move back to Kunming. Tell her in advance to let them deal with the Mengzi night school as soon as possible. Lin Huajun also thought about her future direction. She had no worries in Peiping and decided to stay in the place where she was most needed, teaching and educating people. Later, in the last class of the night school, Lin Huajun announced the incident and encouraged those who are willing to study to continue their studies and pass the middle school and Southwest Associated University. The people of Mengzi came to see them off spontaneously, and Shama Ngawang also came, shook hands with Zheng Tianting, and wished them a smooth journey.
