Everyone was thinking that since the space itself was locked, Reif wouldn't be able to make spatial portals and escape from this place
If thag happens, more and more guards and guardians of the Imperial Palace wouls be notified and arrive to fight him
No matter how powerful Reif was, if all the forces in the Imperial Palace was mobilized, he still wouldn't be able to escape and he would die here, right?
However, even the space is locked and Reif can't use spatial magic then there is still a simple and crude thing he could do to escape
Reif simply has to destroy the fabric of space itself which wasn't necessarily hard for him
After all, he even managed to destroy the fabric of reality and make it so that the future events were completely erased and he in simpler terms, went back in time
If the fabric of reality can be shattered, what more if Reif only wants to destroy space?
