Academician Huang identified the cause of the missile malfunction

Lü Zheng and Shao Shuai came to pick up Huang Li. Huang Wen also arrived, but Lü Zheng, unaware of their relationship, refused to let her join them. Huang Wen felt helpless and couldn't explain. Lü Zheng and Shao Shuai took Huang Li to see the 928 vehicle. Huang Li asked them to get him a set of tool uniforms and set up a bunk bed so he could rest there when tired. Xia Zhuo arrived at the standby hangar. Huang's father hoped Xia Zhuo could help reconstruct his actions that day. Yi Zimeng sang his original songs, while Lang Yongcheng scolded him for playing guitar there. Ouyang Jun came to the library to study English for graduate school entrance exams. Yang Wanjin chased Lü Zheng demanding approval for his discharge report, but Lü Zheng refused to let Yang Wanjin go.
