Serrated Spikes Erupt Underground, City in Chaos AI Image Prompt

A bird's-eye view of a bustling and crisis-ridden metropolis. The city is well-planned, with wide main roads and dense alleys. It has different functional areas such as commercial districts, residential areas, and parks, with rich colors. But at this moment, the city is under an unknown huge threat. The ground cracks without warning, and multiple giant biological spikes with serrated edges erupt crazily from underground. These spikes seem to be parts of some unknown giant beast, covered with a scale-like structure that gives off a dark gray luster and a moist texture. The serrated parts are grayish-white, as if sharpened over a long time, extremely sharp. The appearance of the spikes triggers a series of disasters. In the financial district, the spikes penetrate the bottom of a bank building, glass falls like raindrops, and people flee in panic on the streets. Near the airport, the spikes damage the runway, preventing planes from taking off and landing normally, with thick smoke billowing. On the city's river, spikes rise from the riverbed, splashing water, and bridges are shaking due to the impact. In the sky, several helicopters are circling, trying to observe the situation, their rotors roaring in harmony with the chaotic ground scene. The entire city is shrouded in tension and chaos.
