The vast Dark Domain was boundless, but Lin Feng could clearly sense that he was warping through the Dark Domain at an extremely fast speed. As for how fast the speed was, Lin Feng did not have a direct understanding. However, he felt that it shouldn't be too slow.
"Supremacy Autumn, there's no space in this Dark Domain, and it's boundless. There's no way to warp space. How do you travel? It can't be that every journey takes hundreds or thousands of years, or even longer, right?" Lin Feng asked curiously.
In reality, this was also what he had always been wondering, especially when he saw the Eleventh Celestial Devil King use the "Celestial Devil's traversal technique" previously and actually escape from Supremacy Autumn.
Even the Celestial Devils had such a miraculous traversal technique. Moreover, the Eleventh Celestial Devil King must have a special technique to arrive in front of Lin Feng so quickly.
