龙（Qwen） - 龙（优化版）

Masterpiece, best quality, ultra-high resolution, 8k, photorealistic, CG render, Unreal Engine 5, drgn_stly. Upon a gilded altar, weathered by time and situated high above a sea of clouds, a colossal and slender five-clawed golden divine dragon, its immensely long, serpentine body acting as a living barrier, majestically coils around the altar. Its colossal head hangs down directly over the altar's center, partially obscuring a glowing rune. The dragon's scales are not pure gold, but a biological keratin with a living metallic sheen, displaying a natural gradient from pale gold to rich red-gold. The center of each scale possesses an internal luminescence brighter than the sun, and ancient sacrificial totems are intricately carved upon them. Its long whiskers are like golden threads of energy. The distant sea of clouds churns behind it, and ancient, liquid-gold-like patterns flow across the altar's surface.
