Bartlett put on the ring, and Old Will briefly taught him how to use the Space Ring.
The Space Ring was quite easy to use, but unlike the small Leather Bag, it was opened and closed through mental power to access the Half Plane inside. Ordinary people did not have the same mighty mental power as mages and had few opportunities to use it, so they needed to practice repeatedly in order to use the Space Ring flexibly.
Moreover, due to the lack of mental power of ordinary people, the number of times they could use the Space Ring every day was generally limited. If used too frequently, their mental power would be exhausted, leading to fatigue, dizziness, black-outs, and even fainting. In more severe cases, it could even pose a risk of death.
However, Bartlett did not face such issues. He simply tried it a couple of times and had already mastered how to use the Space Ring. After that, he used it several times in a row without feeling the slightest bit of mental fatigue.
