Riku was well savvied about what happened with his mana pool after the awakening damage him. So when Orlan mentioned the magical power flowing in his body, it was the first thing that came to his mind.
"Mana pool? Are you saying that you are going to fix my mana pool?" Riku asked the old man who was looking at him with excited eyes.
"Mana pool? I do not know what you are saying. Yet, I'm going to fix the flow of your magical power since they are slowly passing inside your body." Orlan explained the situation, by this, Riku can enlarge his mana pool by having proper training.
"I loved to do that, master Orlan! But how do you know that I have a problem with my magical power?" Riku wondered.
