In order to prove to his high school classmates and teachers that in addition to going to college in the world, there are more opportunities and positions to prove his worth, Shen Xiao signed up to join the army and became a fire fighter in the Beigang City Fire Brigade. In the army, Shen Xiao was a "thorn soldier" who stood out in training performance and mischievousness. He had to grab the first work and get the limelight in order to prove himself. Later, facing the teachings of the high school team and veteran Huang Fusheng, and the unhesitating sacrifice of his comrades in the fire, he finally understood a truth. The value and honor of a soldier is not based on vanity and face, but on the interests of the motherland and the people. When you are a soldier king and get results, it is not for yourself, but for others.
