But it has nothing to do with the apartment and everything to do with his Origin. And a few spare bodies to speed things up but the awakened Origin is what makes him impossible to kill even with Mystic Eyes of Death Perception.
@Kotonorris
his bounded field is what kills momentum and stops all movement amongst other functions we never get to see.
Edit: the apartment just allows him to teleport and use his spatial crush technique.
