Guo Zijian was about to leave the military camp after being suspended.But the officers and soldiers of a battalion stopped him at the door. Everyone couldn't bear to leave the battalion commander who led them to train desperately.Guo Zijian suppressed his emotions and persuaded everyone to go back. He knew that the army could not rely on just one person, but this scene still made him uncomfortable.
After returning to his hometown, Guo Zijian met Jing Xiaochun from the Public Security Bureau.Jing Xiaochun was skillful in handling cases and hoped that Guo Zijian could help in the police station after changing his career, but he did not agree for the time being.He returned to live with his grandmother, and in order to help Wu Dongsheng inquire about the installation of prosthetic limbs, he went to see his stepmother who worked in the hospital.

The relationship between Guo Zijian and his father Chen Hanxiao has always been tense.His father blamed him for leaving the army without authorization, but Guo Zijian always cared about his father changing his college entrance examination application without asking for advice.When father and son met, they soon started to quarrel, with neither one willing to give in.
On the other side, Liang Hong saw the insights left by Guo Zijian when reviewing the exercise materials and believed that his ideas were valuable and he should not leave the army easily.When Wu Dongsheng learned that Guo Zijian had been suspended, he rushed to the brigade headquarters in a wheelchair regardless of his physical condition, interceded for Guo Zijian, and took responsibility for the accident on himself.

Suo Jian'an was moved by Wu Dongsheng's persistence.Jiang Shengqiang also admitted in the review that he may not be able to make bold choices like Guo Zijian at critical moments.He took the initiative to invite Liang Hong to analyze the Second Battalion, and the views in the team began to slowly change.
