简介：The Tiger Crouching Cannon is made of wrought iron. It shoots at an elevated angle. Each time it is loaded with seven or eight taels of gunpowder, it can fire one hundred lead bullets weighing five cents. When shooting, one hundred projectiles spurt out in a spray shape with a radius of two feet. All enemies within will be swept away, so the Crouching Tiger Cannon will cause huge damage to enemies in dense formations.
