When they were in the chiliocosm, Lu Ming had seen bubbles perform the space folding technique. However, that was only a chiliocosm. The space was fragile and could not be compared to the prehistoric universe.
However, even in a small chiliocosm, bubbles 'cultivation base had to have reached an extremely high realm to be able to do so.
However, the space in the primeval universe was extremely stable, so it was extremely difficult to fold space.
The folding of space was not as simple as tearing space.
Tearing space apart, any divine Lord realm powerhouse could do it.
However, space has a recovery ability. If you tear space apart or blast space apart, space will quickly recover on its own.
And by folding up the space, the space would quickly recover.
However, the Black Dragon Valley's space had obviously been folded for a very, very long time. It was at least dozens of star years ago. How many years had it been since then?
