Comment by Book on Dragonslayer’s Class Regression - Chapter 15

@Book by compressing the mana energy to a point where it took a solid form

@Book Probably with spatial magic and gravity magic, maybe a little barrier magic for safety.

@Elias i agree with you. they might compress mana and make a storage for that. that also look like mini nuclear reactor

I know that they use compression to make that. I was just curious what kind of thing they used to perform compression on mana.

@Book just think of it as gas cylinder
