Three hours later, Ethan got the hang of that spell. He could now make the size of the mana ball as much as he wanted and then release it.
This was the perfect output practice, but he didn't know if he could control it, compress the mana ball so that it would contain the same amount of mana but the size would be much smaller.
Three hours later he was exhausted. The good thing was that this continuous mana releasing process also made his body somewhat stronger.
He stopped and then remembered that his father was also there. He hurriedly looked at him and saw a calm face could be seen looking at him.
Ethan said, "Sorry father, I lost the track of time. How long have I been practicing?"
Cadis saw that his son finally stopped. He smiled,
"Three hours."
Ethan nodded.
"Father, I think I can manage the output of how much I want, but I can't control it properly. What do I do?"
Cadis puffed up his chest. This brat was finally ready to ask questions.
