Futuristic Underwater Megacity FPV Flight

Immersive first-person flying camera perspective, no visible drone or flying device. The camera launches at breathtaking speed into a colossal futuristic underwater megacity, skimming only centimeters above glowing glass avenues before diving between towering neon skyscrapers enclosed beneath a gigantic transparent ocean dome. Schools of bioluminescent fish, enormous manta rays, and graceful jellyfish drift beyond the glass while the city pulses with cyan, emerald, and violet light. The camera violently snap-rolls through narrow transit tunnels, knife-edges between colossal underwater towers, corkscrews around gigantic rotating turbines, then dives into a vast underwater reactor chamber filled with spinning energy rings and cascading streams of glowing bubbles. Every second the route changes,rapid S-turns through floating traffic, split-S reversals beneath suspended monorails, barrel rolls around giant holographic sculptures, power loops through illuminated coral canyons integrated into futuristic architecture, wall-hugging passes along curved observation domes, and near-vertical climbs through enormous central atriums before plunging back toward the city floor. The camera bursts through a transparent tunnel suspended above the abyss, revealing colossal sea creatures gliding silently outside, ancient submerged ruins intertwined with ultra-modern structures, luminous coral forests, and gigantic mechanical gates opening into deeper ocean districts. The speed never decreases as the camera threads impossibly tight gaps, races through rotating turbine blades, narrowly avoids colossal cargo submarines, then enters an immense underwater energy vortex where entire buildings orbit a brilliant blue core. At the climax, the city gives way to an endless submerged metropolis stretching beyond the horizon beneath the ocean, crowned by a colossal luminous sphere illuminating the deep sea while towering underwater skyscrapers disappear into the darkness.
