Kevin had to admit that what teacher Julian had just explained to them made sense, so he asked him instead, "Is there any other solution to achieve the same result without consuming too much Soul force and still being able to remain mobile to continue fighting if necessary?"
Julian smiled. He had done well to take the time to think of an intermediate solution because, as he had expected, they didn't want to let go of their idea.
So he told them, "There is indeed an intermediate solution, much simpler and which will have the same effect. Instead of trying to create small teleportation portals, you should use the spiritual energy that surrounds us directly."
