For Duanmu Huai, obtaining the Human Magic System on this planet was one of his greatest gains. After all, as long as Duanmu Huai possessed sufficient power and unwavering faith, his magic could destroy anything.

I'm not afraid of Evil Gods, no, no! My nerves are pretty strong. I'm not afraid, no, no, no...

For example, when he destroyed a mountain on that planet earlier, he only needed to expend less than a tenth of his divine power. Afterward, Duanmu Huai returned to the battleship and tried destroying an asteroid, a planet, and a star. His consumption of divine power increased accordingly. By the time he tried destroying a galaxy, he felt that his divine power was already having trouble keeping up.
Strictly speaking, he did not actually need to destroy the entire galaxy outright. As long as he destroyed its stars, the stars' supernovae would naturally finish off the entire galaxy.
It was like blowing up a building. One could use a high-yield nuclear bomb to blast the entire building away, or plant bombs on its load-bearing walls and support columns and detonate them. The result would be the same.
And naturally, Warp Space consumed the most.
Destroying Warp Space—even just a portion of it—required a considerable amount of Duanmu Huai's divine power. To put it in perspective, the divine power Duanmu Huai had expended erasing an entire mountain
