Futuristic city with a futuristic flying saucer in the middle of it

In a galaxy far away，A futuristic cityscape twinkles with lights，Inhabited by advanced robots and creatures from other planets，They all have their own extraordinary abilities，This futuristic city is characterized by sparkling lines、towering skyscrapers、The central square where a group of drones perform aerial shows、A high-speed maglev train station and countless flying machines that create beautiful light trails in the air，Futuristic technology is full of sense - AR 3:4
