Special Forces soldier Lu Zheng accidentally traveled to the world of "Bright Sword" and became a guard beside Kong Jie, the leader of the independent regiment.
When the independent regiment suffered heavy losses and the county brigade was disbanded, Lu Zheng was ordered to rebuild a certain county brigade.
There is no system, no golden fingers, only modern military concepts that are decades ahead of the curve.
Starting from a dozen people and seven or eight guns, he gradually built the county brigade into an elite force of 3,000 people using tactics, training, logistics, intelligence, and popular support.
Li Yunlong is jealous, Ding Wei is poaching, the brigade commander loves and hates him, and the enemy is frightened by the news.
