Seedance 2.0 城市绕行于太阳内部 赛博朋克科幻提示词

Floating cities orbit the central energy core while rivers of plasma arc between structures. Two flight craft skim along magnetic highways suspended above the blazing center. The observer stands inside a transparent chamber hanging directly over the star core. The ending pulls back to reveal the impossible scale of the civilization hidden inside the sun.
