"Unity is strength, unity is strength, this strength is iron, this strength is steel, harder than iron, stronger than steel..." No one knows which instructor proposed singing while warming up, so, the trainees ran like dogs, panted like dogs, and had to howl with all their might like dogs.
Neat rows of troops, thunderous howling, the dazzlings green of camouflage, all ignited the fiery spirit within everyone. After howling twice, without needing the instructor to shout slogans, everyone naturally repeated it over and over, and their steps became much lighter.
Standing in front of the obstacle course, everyone realized that their initial panic and unease had vanished, finally understanding the true purpose behind the instructor's suggestion to sing.
Bai Qingchu nudged Xing Nong: "I used to think it was silly when I saw the soldiers running and singing, but now I get it, some things, if not experienced personally, you'll never grasp their profundity."
