Across the sprawling expanse of the Loess Plateau, stretching for hundreds of thousands of miles, a peculiar, spiral-shaped mountain valley was etched deep into the wind-eroded grains of sand like a scar upon the earth.
The yellow sand, like an enraged behemoth, tumbled and surged, blanketing the sky, obscuring sun, moon, and stars, tinting the world in a monochrome hue of murky yellow chaos.
On the periphery of the valley, a formation flickered with a faint light, barely revealing a large earthen cauldron protecting the entire valley, steadfastly blocking the sandstorm's assault.
Outside the valley, two demons stood amidst the whirling sands.
Their forms were colossal and terrifying, enveloped in dense demonic aura, as if corroding the very air. Their gazes were cold and merciless, indifferently watching the trembling formation, quietly awaiting the perfect moment to shatter this fragile defense.
