An Abnormality

"I don't know the answer, Li." Arthur shook his head. "I'm just as clueless as you are, if not more. But, finding a way to grow stronger is a part of this test, and it's one I believe you will pass." 

"... thank you," Li slowly nodded in thanks. Arthur stood up and left the man to find his answer. 

He lied. 

Arthur knew a part of the answer, if not all of it. The secret to increasing your spiritual energy is to be one with everything, precisely what he did with his Art of Creation. 

However, Li needed to figure out a way on his own. This was also a part of growing stronger. And it wasn't like Arthur could teach him his Art, nor did he know if he can use his Art in such a way, but he knew the concept was similar. 

Dust flew into the air when he landed on the ground. Arthur looked at his golden feet as he felt the spiritual energy in the dust. He knew that everything was a spirit in this realm, even the ground.
