"Sure, I can't grant eight to a single board. Then you just have to overlap."

"Or... overlap? Is it magic?

"No, it overlaps physically. Specifically, it's a five-piece structure."

Tell me, I magically float a picture on the paper at hand.

It's a painting of a sword with five planks attached to it.

Only boards about 2 mm thick, used in the center, are made of dragon fangs, with two pieces of misthrill boards sandwiched on one side and a total of four pieces on the outside.

Lurii stares at the painting with a serious look.

"... this, one board at a time, the magic you impart is different?

"That's the thing. It's symmetrical from left to right, so sometimes we give it the same."

That said, I add the magical information I impart to the pictures on the paper.

[Iron slashing] [Sharpening] [Shock blade] [Abrasion resistance] on the nails of the dragon used in the middle.

On one of its outer misthrill plates is [Magic Strike] [Impact Blade] [Rigidity Enhancement] [Heat Resistance Enhancement].

On the outermost side, [stiffness reinforcement] [toughness reinforcement] [heat resistance reinforcement] [impact blade].

A total of eight types, a total of twelve surgical formulas.

These will reinforce each other, compensate for their weaknesses, and create one sword.

It is a possible grant for Lurii today, a configuration conceived to make the best sword.

"Hey I see... [Magic Strike] or something, you don't have to put it on the blade part to activate it... where did you come up with this way?

"Once upon a time, I thought about ways to give a single weapon a lot of maneuvers. This is one of them."

I'm sure that was... when I was about 700.

When I was even exploring ways to strengthen my weapon as a way to be strong with glory marks, I came up with this way.

I think the sword with the most layers I used to make was a 2047 heavy structure for sure.

Though the sword has become delicate because of too many layers, making it difficult to use in action.

Still, I could cut a sword about Adamantite just by dropping it.

"Mattie, I'm so curious about your life before you came to school......! But do you stick these five boards together? When it comes to securing strength as a sword, you're going to need tremendous machining accuracy..."

"For once, after applying pressure and sticking together, it will be magically fixed...... the surface bumps won't work properly unless they fit by about a thousandth of a millimeter. This configuration is the first time that the structure of the sword supports each other and is effective."

"A thousandth of a millimeter!? Is there some magic that can be processed like that!?

"No, you can't. At least not now."

In previous life, machining, much more precise than that, was also made easier.

But now my crest is not suitable for processing.

Instead of a thousand millimeters, you wouldn't be able to magically give that tenth of the accuracy either.

Neither can Lurii, with his current strength, give that much accuracy.

But there is a way to process it.

"It's not magic... you sharpen it with your hands and a grinding wheel"
