Young Swordsman Slays Demon Lord

16:9 landscape mode, Chinese animation cinema-quality visuals, golden and white holy light tones.
0-3 seconds: Dark clouds gather above the cliff. The young swordsman kneels, holding an ancient sword embedded in the rock. His baby face and round eyes are single-eyelided. His black hair is messy and soaked with sweat. The runes around the ancient sword buzz as the camera slowly rotates downward from above.
4-7 seconds: The sky demon army presses in. The leader holds a black war halberd, has a square face and a full beard, green ghostly flames burning in his eyes, waving to signal the army to attack. Countless black arrows shoot toward the youth like locusts, and the camera zooms in quickly.
8-12 seconds: The young man suddenly draws his ancient sword, golden light soaring skyward to disperse the dark clouds. Dragon patterns awaken on the blade and roar like a dragon. The young man swings his sword, unleashing golden sword energy that turns all arrows to dust. The camera follows the sword aura's trajectory and advances at high speed.
13-15 seconds: The young man rises into the air, a shadowy golden dragon appears behind him. He strikes at the demon general with a sword, but the demon general raises his spear to block but is severed by a single sword strike, cleaving from shoulder to side. Golden light envelops the entire battlefield, the demon army retreats in terror, the scene frozen on the silhouette of the youth holding a sword looking down, with sunlight piercing the clouds behind him.
Sound effects: Sword blade hums, dragon roar shakes the heavens, arrows shatter, demons cry out in alarm.
