Why did Xu Sanduo compete with Wu Ban’s deputy in push-ups, running, etc.

Before that, the rumors about the disbandment of the Seventh Company of Steel were based on "tons of equipment", and 561 faced the rumors that the Seventh Company was about to be reorganized and Xu Sanduo gave in to Wu Liuyi in every test. He wanted to get Sanduo to come out for individual training and let others see the prowess of the soldiers of Steel Seventh Company. When Xu Sanduo wanted to end this meaningless game, 561 said, "Seventh Company has no squad leader who admits defeat. Let's compete again."

To vent, to prove!
