The Whitestar that originally surrounded Whitestar still had air, but now Whitestar had become a vacuum, and Fang Zuo, torn with emotion, hadn't even realized this. Fortunately, the door of the spacecraft came with a protective feature that automatically closed at the moment of depressurization.
Now Fang Zuo actually had time to take a good look at this so-called Whitestar.
The white ground wasn't made of rock but a very special material. He could see that there were enormous runes on it, which together formed an Array that covered the entire planet. Fang Zuo didn't know what the Array meant, but it must be incredibly powerful to cover the whole planet. Perhaps that's why Whitestar could teleport through the universe?
But with no air outside, how could he get out? He didn't have the specialized armor for it! Go back?
