Lin Yu, an ordinary young man living in a quiet town, spends his days guarding the grocery store and has a simple vision for the future. However, the sudden arrival of war broke the peace of the town and instantly plunged it into a whirlpool of chaos and fear. The shells roared and his home was shattered. Lin Yu was rescued by soldiers at the moment of life and death, and he embarked on a military journey from then on.
At the military base, Lin Yu went from being ignorant when he first joined the army, to undergoing rigorous training and cruel battles, and gradually grew into a brave and fearless soldier. He fought side by side with his comrades, charged into battle amid hails of bullets, and faced fierce enemy attacks together. He was in desperate situations many times but relied on his tenacity and extraordinary wisdom to avert danger. Tempered by the flames of war, Lin Yu not only achieved self-transformation, but also deeply understood the cruelty of war and the preciousness of peace. His friendship with his comrades was sublimated in blood and fire, and together for the belief in protecting his homeland and defending his country, he wrote a magnificent chapter in the smoke of war.
