"But it does use a lot of mana." Amelia looked at her brother in confusion.
The two brother and sister didn't quite understand why they were using the same magic spell but the consumption was different.
"Did you pour out all of your mana when using the magic spells?"
"No way, I can't even control how much mana I use." Amelia frowned.
"You can… wait, you never control the amount of mana when you use magic spell?" Samuel seemed to have realized something and looked at his sister.
"Yes."
"…When we get back, you will start 12 hours of daily mana control training."
"Ahhh, Brother! No, not 12 hours!"
But Samuel was not moved when he heard his sister's words. "You can control how much mana you used in a magic spell. If you don't learn to control it properly, you will end up wasting so much mana."
