Science fiction Book Cover Design (Evoking 坚持不懈)

Set against a dark, stormy backdrop, the cover features a monumental fantasy scene. Uber-dramatic, swirling black clouds dominate the upper half of the frame, laced with streaks of ominous purple lightning that hint at the looming battle. In the foreground, the heroic figure of 萧凡 stands resolute, holding the glowing 天璇瓶, which radiates a mystical blue aura, creating a striking contrast against the dark surroundings. To his left, 赵平生 is mid-action, his eight-sided 八卦镜 alight with golden runes, casting dynamic streaks of light that cut through the murk. On the opposite side, the shadowy 黑袍人 looms threateningly, holding a sinister staff embedded with a jewel radiating pulsating crimson energy. Beneath them, cracked earth reveals an ancient 石碑 with glowing inscriptions that subtly hint at the story's central mysteries.

The book title "天璇瓶主萧凡" is rendered in a bold, modern Chinese calligraphic font with subtle metallic effects, glowing faintly as though infused with power. The author name "侯昊宇" in a simpler serif font is placed subtly at the bottom, also with a faint metallic glow but in silver-gray tone to maintain subtlety.

The title is centered and positioned near the top of the cover above the dark sky, offset slightly by cracks of light from swirling clouds. The 天璇瓶 and 八卦镜 serve as visual anchors in the middle foreground, with both objects' dynamic lighting guiding the viewer's eyes. The black-robed figure is placed to the right, adding tension with his crimson array of power echoing into the background and creating diagonal symmetry across the frame. The glowing 石碑 runs along the lower quarter of the cover as the visual "foundation" upon which everything is based visually.
