After Xia Lan arrived in the army, she encountered an unexpected situation during her first mission with the team (a teammate was shot and communications were interrupted). Under Lu Feng's command, she calmly completed first aid, which impressed Lu Feng. During daily training, Xia Lan discovered that Lu Feng often trained with pain due to old injuries, so she took the initiative to formulate a rehabilitation plan for him. Later, the army received an urgent mission to "rescue the hostages." Lu Feng led the team deep into enemy lines, and Xia Lan accompanied the team to provide medical support.
