For example, have you ever heard of stainless steel being used to build airplanes?
The idea was simple: brute force made up for everything.
What good were advanced composite materials?
Were they as useful as stainless steel?
This tank was just like that.
Its engine used a dual magic-and-mechanical hybrid design, with both its mechanical and magic-powered components based on mature technology.
It was just a little absurd.
We need to introduce a bit of knowledge about the magic system here.
Magic was cast by channeling mana through special symbols, special vibrations of a particular frequency—such as chanting, spells, or dragon tongue—or Mental Power.
And mana itself contained an absurd amount of energy.
But magic had a low conversion efficiency. The more powerful the spell, the more mana it took to cast.
Take a game, for example. A fist-sized Fireball Technique might cost you five mana, while a fireball the size of a person might cost you twenty.
That wasn't because mana was weak or had little energy. It was because the conversion efficiency was poor.
So mages needed to build magic circuits inside their bodies—like high-speed railways for transporting mana—
and expand their mana reserves.
When casting, the more powerful the spell, the more magic arrays would appear.
You could think of them as electrical circuits.
But the water produced by a 1st Rank low-level spell was like water spurting from a toy squirt gun, while a 9th Rank high-level spell produced a high-pressure jet with absurd force.
There was no fundamental difference between the two. For the same weight of water, the amount of mana consumed was completely different.
The only difference was the power behind it.
That was common knowledge about Water Magic.
Fire Magic's power came from temperature, so it couldn't take the same shortcuts as
