Ryu sighed. He had thought this might happen, but hearing it outright still dampened his mood. If he could enter the Moon Realm now, his speed of cultivation was increase explosively, especially with Ailsa by his side.
The Moon Realm was a special Realm that gave rise to the Awoken Moon Sect's namesake. According to their history, something Ryu was very familiar with as he researched the Moon Realm for his mother, the Founding Members of the Sect were the beneficiaries of a fragment of a Legacy from that Realm.
As Toria had said, the Moon Realm was no different from this Realm. Though, it only had one Plane, and not multiple. Still, it was a holy land for yin path cultivation.
