古代玻璃管中漂浮的外星水晶城市

In an ancient crystal vacuum tube, an alien summer city floats in the air, supported by advanced technology. The buildings are constructed of crystals and metals that glow with iridescent light. Alien plants and flowers adorn the garden, creating an atmosphere of relaxation and enjoyment. The city is illuminated by a warm, bright light, which filters through the liquid glass windows, allowing the alien breeze to enter. The tube rests on an oak desk, in a room filled with light and warmth, creating a sense of wonder and enchantment.
