Rhein said nothing about what Tree Spirit had done.
This hidden room had been discovered by Angel in the first place, and being able to enter it had also been thanks to Angel's Domain Field. Even under the Kurna Contract most commonly used by adventurers to divide the spoils of ruin exploration, Angel should have received the largest share.
Thus, there was no dispute over giving the teleportation array disc to Angel. Besides, the others would have little use for the disc. At present, only Angel could safely use it without being affected by the Nightmare Light.
Angel did not refuse. The teleportation array disc was an excellent resource to him as well. At the very least, when he went out and wanted to return in the future, it could save him the material costs of casting a Planar Corridor.
Once Angel had accepted the teleportation array disc, Rhein said, "When you have time, I'll take you to test this teleportation array disc's maximum transmission distance."
Angel nodded. If it truly could teleport across planes, then just as Tree Spirit had said, it would become a strategic tool.
For example, it would be an absolute trump card for smuggling resources from other worlds. Resources from other worlds, whether living creatures or magical materials, were extremely valuable. Unfortunately, the planar teleportation arrays had always been controlled by the Extreme Sect, so smuggling resources from other worlds had never been easy.
Of course, Rhein could also open a planar passage, but the materials it consumed were far too expensive, making it not worth the cost.
Therefore, if the array disc could conduct planar teleportation, then even if Angel were the only one who could teleport, it would not diminish its value by much. At worst, they could lend Angel a Wizard Garden
