简介：The cavalry are the elites that both sides rely on the most. This fight can be described as the sky is shattering and the earth is shattering, and the sun and the moon are dim. When the two armies met, there was a bloody rain, the horses neighed, and countless cavalrymen fell off their horses. In the flash of swords, their heads were taken off by the enemy, or they were trampled to pieces by the impact of the horses.
