A dark-style grassland cavalry army, forming dense formations, charges with the speed of a gale. They wear fur tents on their heads, leather armor, exuding a cold, solemn, and fierce aura. At their waists hang curved blades made of cold iron, and they carry quivers on their backs. Riding warhorses clad in black iron armor, they hold bows and arrows in a mounted archery stance. In the reflection of light and shadow, the metal parts emit a unique glow, creating an imposing scene of tens of thousands of soldiers. Movie effect. Live-action filming.
