Among the inherent special abilities, Rein was already using the Eye of Truth so he had no need to test it out. And as for his perfect body, to test that out he needed to get hurt and with this baby body of his, Rein was not willing to do anything too dangerous. So for the time being, he decided to test out his spatial manipulation ability.
First Rein tried to create a portal. He was successful in the very first chance and was able to create a portal that opened a few meters ahead of him. So next he started to test the distance limit of the portal.
After he was able to create a portal even on the furthest corner of the room, he stopped. This much distance was already quite good and Rein felt that he was nowhere near his limit. So he decided to do this test again in a more open area.
