Chapter 103
"It's true that augmenting eight magic with one board isn't feasible . Then you just need to fold them . "
"F . . . fold? You mean the magic?"
"No, you physically fold them . A fivefold structure specifically . "
As I said that I magically drew a picture on a paper I held on my hand .
It's a picture of sword made of five boards that have been stuck together .
The core is made up of one 2mm thick board made from a dragon fang, and the outer part consists of two mithril boards on each side, totaling at four .
Ruli stares at the picture with a serious look on her face .
" . . . Are the augmented magic on each of these boards different?"
"That's right . They're symmetrical though, so you can put the same augment on them too if you wish . "
Then I add information about the magic that will be augmented on the drawn paper .
The dragon claw used as the core gets, 【Steel Slash】, 【Sharpen】, 【Impact Blade】, and 【Wear Proof】 .
The mithril boards on top of it get, 【Mana Strike】, 【Impact Blade】, 【Toughness Reinforcement】, and 【Heatproof Reinforcement】 .
The outermost boards get 【Hardness Reinforcement】, 【Toughness Reinforcement】, 【Heatproof Reinforcement】, and 【Impact Blade】 .
12 spell arts of eight types in total .
Each of them mutually strengthens one another, compensating their weakness and becoming one sword .
It's a composition I've come up with in order to create the strongest sword with augments that are available to Ruli right now .

"I-I see . . . . So 【Mana Strike】 can be invoked even if it's not implanted on the blade part . . . . Just where did Mathi-kun get the idea for this?"
"A long time ago, I thought up various ways to augment multiple number of spell arts on a weapon . This is one of those . "
If I'm not mistaken, that was . . . when I was around 700 year old .
I came up with this method when I was singlemindedly searching for a way to reinforce my weapon to strengthen Glory crest .
The highest layered sword I made back then was a 2047-fold structure .
I added too many layers on the sword it ended up becoming too delicate, and difficult to use in an actual combat .
Nevertheless, it was a sword that could cut adamantite clean just by dropping it on the metal .
"I'm really intrigued by Mathi-kun's life before you came to this school . . . . ! But this means these five boards have to be stuck together? We'd need a terribly advanced processing method to ensure its strength as a sword . . . "
"We can do it by applying high pressure on the boards and then affix them together with magic . . . . but the surface has to be at least 1/1000 millimeter uniform, otherwise the effect won't be as good . Since this composition will only show its effectiveness when the structures of the sword support each other . "
"1/1000 millimeter!? You can use magic that can do that!?"
"Nah, it's impossible . At least, I can't do it now . "
I could easily use processing magic that's far more precise in my past life .
But the crest I have now isn't suited for processing .
Let alone 1/1000mm, I probably can't even get to 1/10mm .
Neither Ruli can reach that too with her current capability .
But there is a way to process them .
"Not with magic . . . . But we shave them with our hands and whetstones . "
