After the talk with his grandfather and his father about the fusion system, Caleb returned to his room. He did not reveal the full capability of his ability to them. They only know that he can fuse two things. However, they did not know that he could fuse multiple things simultaneously, infinitely. He knew that they must have thought that there was some kind of restriction on how many times a day he could use his fusion system, and he said that he could only use it 3 times to 15 times on a good day.
