自然都市接管序列

一段电影级奇幻灾难序列，展现自然力量突然覆盖现代都市的场景。 0–3 秒：宁静的夜间城市。路灯在空旷的街道上闪烁，车辆停放，建筑反射着平静的黑暗。城市中心地下的地面开始出现轻微震动。 3–6 秒：路面突然剧烈裂开。巨大的发光根系从地下喷涌而出，撕裂道路、地铁线路和混凝土结构，整条街道开始抬升并分崩离析。 6–9 秒：生长速度异常加快。一根巨大的树干升起，高度超过摩天大楼，势不可挡地穿透建筑。窗户破碎，碎片缓慢坠落，绿金色的光芒在树皮中脉动。 9–12 秒：高耸的枝干在天际线蔓延，伸入风暴云层。叶片散发出柔和的生物发光，照亮了整座城市。鸟群和风在扩张的结构周围盘旋。 12–15 秒：最终超广角电影镜头。巨树完全主宰了城市，根系如同血管般融入街道，发光的枝干刺破上方的云层。大都市现已转变为一座充满生机的神话森林与城市混合体。 风格：超电影级写实，自然奇幻接管，宏大的环境尺度，生物发光特效，毁灭与重生的戏剧性对比，体积光，IMAX 风格构图，精细的城市向自然转化，电影级调色。

A cinematic fantasy disaster sequence where nature suddenly overrides a modern metropolis.\n\n0–3s: Quiet nighttime city. Streetlights glow over empty roads, cars parked, buildings reflecting calm darkness. A faint vibration starts beneath the ground in the center of the city.\n\n3–6s: The pavement suddenly cracks open violently. Massive glowing roots erupt from underground, tearing through roads, subway lines, and concrete structures as the entire street begins to lift and split apart.\n\n6–9s: The growth accelerates unnaturally. A colossal tree trunk rises through skyscraper height, pushing through buildings without stopping. Windows shatter, debris falls in slow motion, and green-gold light pulses through the bark.\n\n9–12s: Towering branches spread across the skyline, reaching into storm clouds. Leaves emit a soft bioluminescent glow, illuminating the entire city. Birds and wind swirl around the expanding structure.\n\n12–15s: Final ultra-wide cinematic shot. The giant tree fully dominates the city, roots integrated through streets like veins, while glowing branches pierce the clouds above. The metropolis is now transformed into a living, mythical forest-city hybrid.\n\nStyle: ultra cinematic realism, fantasy nature takeover, massive environmental scale, glowing bioluminescent effects, dramatic destruction + rebirth contrast, volumetric lighting, IMAX-style framing, detailed city-to-nature transformation, film-grade color grading.
