A modern soul accidentally fell into the war-torn northwest of Shanxi in 1940. He accidentally became an ordinary soldier of the legendary army-the Independence Regiment. Faced with the ferocious Japanese aggressors, the complicated war situation, and the iron-blooded soldiers represented by the "Tu Emperor" Li Yunlong, he relied on his deep understanding of the plot of "Bright Sword" and his military qualities that transcended the times. In this heroic land in northwest Shanxi, he gradually grew from a wounded recruit to a real soldier. In Langwogou, he used his wisdom to see through the top Japanese soldiers, laying the foundation for the victory of the ambush battle; in the training ground, he used his unique insights to improve assassination techniques, winning the respect of veterans; he was even called upon in danger amidst a hail of bullets, leading his team to perform extraordinary feats, and finally broke the rules with his strength and was promoted from an ordinary soldier to an officer, becoming another rising star under Li Yunlong. In the war-torn era, he not only had to learn Li Yunlong's "Sword-Showing" spirit, but also to combine modern military concepts with cruel battlefield realities in the baptism of blood and fire, leading the brothers of the Independent Regiment to show their swords to the invaders again and again, and write his own iron-blooded legend in the high mountains of northwest Shanxi. From squad leader to company commander, every step of his growth was accompanied by a desperate struggle against the Japanese invaders, shining with the loyalty and responsibility of a soldier. This is the story of a modern soul who, in the flames of the Anti-Japanese War, used blood and wisdom to practice the spirit of "Bright Sword" and eventually grew into a famous general.
