自然风光：贝加尔蓝冰

Wide shot at a low angle of frozen Lake Baikal in winter, the vast expanse of deep translucent sapphire-blue ice stretching to the horizon, its surface laced with intricate white crack networks and frozen methane gas bubbles suspended in the clear ice like tiny pearls. Turquoise-blue ice hummocks rise in shattered, crystalline ridges in the middle distance, glowing from within where the low sun shines through. A snow-covered rocky shore with a few snow-laden pines frames the left edge, and distant mountains fade into a cold blue haze. The ice underfoot shows a beautiful mix of milky white and deep blue tones with fine frost patterns. Sky: clear, cold pale blue with a low, sharp sun. Lighting: low winter sun from the right, piercing through the ice and creating glowing blue translucency. Color palette: sapphire blue, ice white, pale cyan, cold grey. Crystalline texture detail, 4k
