Abel realized Grand Duke Edwina's intentions. This large teleportation circle could make the teleportation between his teleportation circle in Harry Castle easier.
If he didn't have this large teleportation circle, Abel would need to transit through many other teleportation circles every time he went back to the Duchy of Carmel, and his teleportation history would be marked down.
If he teleported too many times, people would grow suspicious of his identity.
Abel was very happy with this large teleportation circle. If he wanted to use this large teleportation circle very often, he would need to change all the gems in the operation room into top-level gems.
This wasn't a problem to Abel at all. His top-level gems couldn't be given out, so there wasn't a problem no matter how many he used personally.
