At this point, if there was still a way to make him move faster, it was to reduce the weight of the Void Return Realm.
For other Realm Lord Realm experts, this suggestion was as good as saying nothing. If they could resolve that drawback, Realm Lords who had broken through through their own strength would immediately seek out a plane to form a symbiotic bond with.
After all, having a plane or not made an enormous difference to a Realm Lord.
For a Realm Lord with a plane, the greatest drawback was the impediment to mobility. As for the later difficulty of advancing their cultivation realm, which required raising their symbiotic plane alongside them, that did not even enter most Realm Lords' considerations.

Meanwhile, the substantial increase in safety provided by having one's own plane was a tangible benefit right before their eyes.
It was therefore a matter of trade-offs, depending entirely on whether a Realm Lord wanted greater security or the ability to flee without hesitation when danger arose, without damaging their foundation.

But if the Void Return Realm was gone, restoring his backup would only restore his cultivation realm. It could not restore the Void Return
