William wasn't lying, as this was one of the aspects that made karma masters quite ferocious at the outer world. They might be considered weak compared to other masters in terms of pure strength and such. But that didn't mean they could be taken lightly.
William knew that Thomas needed more than thinking and training to get there. The main obstacle was related to the quality of spirit power in this world, and the lack of any suitable monster spirits that Thomas could absorb.
Despite knowing all this, William didn't even think twice about giving hints to Thomas. He wanted to prepare the loyal youth to what would happen when going to the outer world, a move that he decided to adopt from now on when dealing with his friends and carefully selected team.
"Hmm, if so then there must be a way to do it…" Thomas got lost in his thoughts, which made William slightly nod in satisfaction.
