The army was a melting pot, and being a soldier was considered a sacred profession. However, soldiers were also humans, each with their own personalities and temperaments. After joining the army, they were prepared to make sacrifices for their country when needed. Yet, they were not expected to be perfect in their personal lives.
Deng Hai, from his perspective, believed he was not wrong in wanting to compete and challenge Wang Ye when he became the deputy class monitor. However, Ye Sanshi intervened and reminded him of the importance of unity and teamwork in the army.
Ye Sanshi looked at Deng Hai lying on the ground and the people around him. He recalled the song "Unity is Strength," a lesson that might have been learned during primary school or possibly during their time in the army. Ye Sanshi emphasized that being alone might be acceptable outside the army, but once they joined, unity was paramount.
