The devil looked at that in shock. It's not that he wasn't paying attention to Fleus and the other devils. Instead, it was that Rean literally bent space! He was absolutely sure that Rean was in the Void Tempering Realm, so it shouldn't be possible for him to bend space yet. After all, that only happened in the next level, the Space Bending Realm!
In any case, he underestimated the twins. Both of them were in the Late Stage of the Void Tempering Realm. That meant they weren't far away from having the ability to bend space. The twins were able to use Spatial Powers when they were still in the Transition Realm, so the same thing happened here. After getting close to the next realm, they finally understood how bending worked.
