kling-video/v1.6/pro/text-to-video Prompt: A hyper-realistic cinematic video of a bustling African mega-city shot on an 8K IMAX lens, golden hour. Suddenly, the sun begins to turn completely black while the entire sky bleeds into glowing purple lightning veins. Cars stop. People look up in slow motion, their faces lit by an otherworldly glow. A giant mysterious floating cube made of dark glass descends from the sky, silently absorbing the sunlight. Camera zooms slowly into the cube until we see an entire alternate universe inside it — cities floating upside down, waterfalls flowing into the clouds, and billions of stars swirling around. Epic atmospheric soundtrack.
