Ki was an important lesson Ray needed to learn. So far, everyone he had encountered who could use Ki had completely overpowered him—Harry, the dark guild, and Delbert. If he couldn't unlock his skills, then he needed to learn to use Ki.
The old man made Ray stand about a meter away from him before beginning his explanation.
"Before we start practicing Ki, you need to understand what it is and how we can use it," the old man said. "Ki is very similar to how mages use mana. Mana is a force borrowed from the world. A mage's mana pool determines how much of the world's energy they can control—how many spells they can cast or how powerful those spells can be. So, if mana comes from an external source, what do you think Ki is?"
"Ki is the power from inside our bodies," Ray answered. They had learned the basics in school, so he assumed the old man was just testing his knowledge.
