Which is better to reward the mysterious fortress of stars?

Black technology. There are two rewards in the event chain of the mysterious fortress of the stars, one is black technology, and the other is that the whole galaxy becomes a wasteland planet. Although black technology is very powerful, it can blow up a bunch of planets with one explosion, and there are 30 squares of waste Saturn, which is very good. Mysterious fortress is a guardian space creature in the interstellar space, and it needs to install DLC Leviathan to appear in the game.
