At the end of the Eastern Han Dynasty, the Yellow Turban Rebellion broke out. Chen Ce, a modern history student, accidentally traveled through time and became a Yellow Turban pawn who was about to be executed by the army. At the critical moment of life and death, he awakens the ability of "barracks deduction". As long as he has enough food, iron ore and population, he can quickly build barracks and train elites. Facing the troubled times that were about to collapse, Chen Ce did not choose to rely on any princes. Instead, he started by rectifying the remnant troops and relieving the people, and gradually incorporated refugees, craftsmen, and broken soldiers to establish a new army with strict discipline, self-sufficiency in farming, and powerful combat capabilities. He defeated the official army with continuous crossbows, catapults and cavalry raids, captured cities and territories, and swept across the Central Plains. Cao Cao tested the enemy with his strategy, Yuan Shao suppressed the situation with his powerful troops, Liu Bei gathered the crowd with his benevolence and righteousness, and Chen Ce used military camp deduction and strong organizational ability to break the situation. In the end, he rose from the yellow turban thief despised by everyone to the supreme position in the world, establishing a completely different new era.
