Why did shi huangi's armies destroy city walls and take weapons from people they conquered?

Shi Huangdi's armies destroyed city walls and seized weapons from conquered territories to consolidate power and eliminate potential resistance. By dismantling fortifications, they aimed to prevent cities from defending themselves and fostering rebellion. Additionally, disarming the populace reduced the threat of uprisings and ensured greater control over the newly unified empire. This strategy was part of Shi Huangdi's broader efforts to centralize authority and maintain stability across his realm.
