The students withdrew to the back mountain, but they did not expect the Japanese plane to fly directly to the school this time. Bi Yunxiao yelled for the students to run quickly, Cheng Jiashu remembered that the instrument was still in the laboratory, and ran back immediately, Bi Yunxiao and Lin Zhen followed behind him. The three quickly put away the equipment and ran into the school's emergency air-raid shelter to escape. Ding Xiaowu's uncle was a Japanese spy. After he sneaked into the Southwest Associated University, he specially placed lenses around the laboratory to facilitate the Japanese army to lock the laboratory for bombing. When the number of bombings decreased, the three evacuated the air-raid shelter. Cheng Jiashu returned to the dormitory to get the onions Lin Huajun gave him, but was trapped in the dormitory. The dormitory was bombed and caught fire, and the door was locked. Wen Jie heard Cheng Jiashu's cry for help, but he refused to save him.
Many students were injured in this bombing. Shuangxi asked Bi Yunxiao and learned that Cheng Jiashu returned to the dormitory to get the pot of onions. Another student who had just escaped from the school said that the school was bombed and the dormitories were also destroyed. Shuangxi and Bi Yunxiao rushed back to the school dormitory immediately, and rescued Cheng Jiashu at a critical moment. Before leaving, Wen Jie told Cheng Jiashu that Lin Huajun was waiting for him at the Nanping Grand Theater, so after he was rescued, he ran in the direction of the Nanping Grand Theater. Lin Huajun was on the street and witnessed a couple who died under the bombing of the Japanese army in order to protect their child. Cheng Jiashu rushed to protect Lin Huajun and the child on the ground. After the bombing, a bunch of wounded people were left licking their wounds and suffering the loss of loved ones.
Mei Yiqi learned from Zheng Tianting that a small number of students were injured, more than a thousand books were damaged, and all the laboratories were blown up. After he arranged some matters for Zheng Tianting, Ms. Miao Lanying from the big pharmacy brought some Baiyao over, hoping to help. Cheng Jiashu was nowhere to be seen. Bi Yunxiao said that after he was rescued from the dormitory, he went to Nanping Grand Theater to look for Lin Huajun. Now that they are both missing, it is unknown whether they are still alive. Mei Yiqi was very worried, and immediately asked the students to find someone. At this time, Cheng Jiashu, Lin Huajun, and the child Xiaokui who had just lost his parents were trapped under the rubble. Cheng Jiashu struggled to dig a hole, and the long-lost sunlight came in. Onion burst into tears.
Ah Mei heard Cheng Jiashu's cry for help, and immediately asked everyone to come and save people. Wen Jie on the side also pretended to save people. Under the ruins, Cheng Jiashu understood many things, so he no longer chose to escape, and bravely confessed to Lin Huajun. He wants to take care of her for the rest of her life and be a useful person. Lin Huajun felt that Cheng Jiashu had really changed. She agreed to be with Cheng Jiashu and decided to go back to school to continue her studies. Luo Heng decided to go to the front line of the battlefield. Ye Runqing reminded him that he could stay as an instructor and not give up his young life so quickly. Back then when Ye Runming said he was going to Yan'an, Runqing didn't understand him at that time, if he could give her another chance, he would definitely support his brother with all his strength, and now she does the same for Luo Heng.
Cheng Jiashu and Lin Huajun were rescued and admitted to the hospital. Shuangxi came to see them first, followed by Pei Yuanzhi. Lin Huajun asked if she could come back to resume classes, and Pei Yuanzhi said yes. For the repair work of the school building, Zheng Tianting received financial support from Fudian Bank, and he wanted to rush back to the school to tell the principal the good news. Luo Heng left a letter and rushed to the battlefield without saying goodbye. Ye Runqing looked at the letter and burst into tears. Lin Huajun was staying for a few days, and Cheng Jiashu specially asked Shuangxi to cook some delicious dishes, but due to rising prices, Shuangxi couldn't cook without rice.
