scene concept illustration. the massive underground sword tomb. the ground is covered with tens of thousands of rusty and broken ancient swords, with their handles facing in different directions and their blades covered with white frost. hundreds of intact flying swords are suspended in the air, rotating slowly, with their bodies emitting a cold light that is a mixture of dark blue and green bamboo. in the distance, there is a huge stone statue partially buried underground, with only the upper part remaining. blue-white light points and fine iron shavings are floating in the space. there is no natural light source; all the light comes from the self-luminosity of the sword blades. shot from a low angle at 25°, ultra-wide angle, 8k ultra-high definition, with a realistic film texture, emphasizing the contrast between the metal rust and the self-luminosity.
