Epic Mecha Warrior on Ancient Battlefield

A dramatic, epic cinematic vertical video (9:16) of a massive 20-meter tall futuristic white and gray mecha robot with heavy armor, glowing blue energy core, and powerful weaponry, rampaging through a massive ancient Chinese battlefield. The giant robot fires intense bright blue-white energy beams and lasers from its arms, stomping the ground with enormous force, cracking the earth, and kicking up huge clouds of dust and debris. The scene is filled with chaos: thousands of ancient armored warriors on horseback and on foot charging and attacking, red and black banners waving, traditional East Asian pagodas and fortress buildings in the background. Massive orange fire explosions, smoke, flying debris, and destruction everywhere as the mecha dominates the battlefield. Dynamic camera movement: starts with a low-angle hero shot on the robot's upper body, then tilts down to its powerful legs crushing the ground, orbits around the mecha during action, goes to wide battlefield shots showing the scale, and ends with a sweeping high-angle view of the robot standing amid smoke and chaos. Cinematic lighting with dramatic sunlight rays cutting through dust and smoke, intense motion blur on fast-moving horses and warriors, highly detailed, photorealistic, epic war movie style like Pacific Rim meets ancient warfare, 14 seconds duration, 4K, ultra-realistic textures, powerful sound design implied.
