One Sword Breaks Dawn Video Prompt for Seedance 2.0 (Fantasy Action)

16:9 horizontal screen, Chinese animation cinematic quality, gold and white holy light color palette. 0-3 seconds: Dark clouds gather above a broken cliff. A young swordsman kneels, gripping an ancient sword plunged into the rock with both hands. He has a baby face with round eyes, single eyelids, and messy black hair soaked with sweat. Runes flow around the ancient sword, emitting a hum. The camera slowly rotates and descends from an overhead view. 4-7 seconds: The demon army presses down from the sky. The leading demon general holds a black war halberd, has a square face with a beard, and green ghost fire burns in his eye sockets. He gestures for the army to attack. Countless black arrows shoot towards the young man like locusts. The camera quickly pushes in. 8-12 seconds: The young man suddenly draws the ancient sword. Gold and white light shoots up into the sky, dispersing the dark clouds. The dragon pattern on the sword awakens and emits a dragon roar. The young man swings the sword, cutting out a golden sword energy that pulverizes all the arrows. The camera follows the trajectory of the sword energy at high speed. 13-15 seconds: The young man steps into the air, and a golden giant dragon phantom appears behind him. He strikes the demon general with a single sword. The demon general raises his halberd to block but the weapon is cut off and the general is split from shoulder to torso by the sword. Golden light envelops the entire battlefield. The demon army retreats in terror. The frame freezes on the silhouette of the young man holding the sword and looking down, with sunlight piercing through the clouds behind him. Sound effects: Sword humming, dragon roar shaking the sky, arrows shattering, demon screams. Prohibited: Any text, subtitles, LOGO, or watermark.
