The collapse of the dimension was like a sudden fracture of a supporting point, followed by a widespread devastation, which was accelerating.
However, dimensions, consisting of rules, do not truly shatter in an instant like buildings.

Taking advantage of this opportunity, several members of the Glass Clan at the Peak of Rule Integration Realm led all members of their clan from the Central Mountain Range out of the dimension, throwing out their most valuable precious treasures.
If you don't offer these treasures, the imperial sovereigns of over a dozen races would not let you leave easily.
Choosing between money and life wasn't difficult; the Glass Clan chose their lives.
