Arnold's explanation continues.
"The pieces of magecrystal are encased in magecrystal resin, and then the whole is formed into shape, consciously adding more magical power.

"Why is that?"
Gloma Trey interrupted with a question.

"The extra magical power from the forming process causes each piece of the magi crystal to turn in a certain direction.

It was also Katya who took a shine to the effect.
"I don't know how it was back then, but now you can make a magic crystal (magi crystal) that would cost about one million dollars for one-tenth of that cost. I don't know how it was back then, but it would mean that a magic crystal (magi crystal) that would cost about a million dollars now can be made for a tenth of that.

Cachier is always greedy for cost reduction.
"Well, ......, how about a method of strengthening metal materials?"

"Yes, I'd like to hear about it."
Jin is very enthusiastic about this.

He hoped that if Arnold knew about it, it would not be a common method.
"It is not limited to metals, but if you strengthen the molecular structure, you can make it stronger. There are several ways to strengthen it, but there is one method that was developed during the war.

"Yes."
"It is known that common metals undergo work hardening. It is done artificially, uniformly throughout the metal. But it can only be used for things like armor or the exterior of a golem."

"We hit the finished product with a small ball of adamantite that we have prepared in advance. The surface will be a little uneven, but it will be hard and scratch resistant.

Shot peening is a type of cold working.
It is a process in which countless hard balls collide with a metal surface at high velocity (these balls are called shots).
The metal surface becomes pear-shaped and lusterless.

However, the hardness of the surface is increased and compressive residual stress acts on the surface, which has an effect on metal fatigue.
In addition, wear resistance and heat dissipation are also improved.
Furthermore, it has a wide range of applications due to its low material dependence.
