New Rooms, Back On Track
William showed Tia to her room next, which was made based on a gym in his old world. There was even a boxing ring in the center, with Perfect Array Puppets configured to react to her Mana and would spar with her whenever she wanted.
As long as her strength didn't exceed the Nascent Soul Realm, the Puppets would be able to slowly repair any damage that she caused, so they should last a while.
Gunther's room was reminiscent of an ice castle, with Arrays that rained a light snow on command from within the room. His room was very cold, but the temperature could be adjusted to a normal level in case he had a "special visitor" at night and he wanted them to be comfortable.
In addition to these Arrays, William knew that Gunther was very interested like the rest in learning Arrays of his own, so he added a few Ice-Magic specific Arrays from the Basic to the Advanced level, which he left for Gunther to decipher himself.
