「Kiseri-san, what happened!?」
「This… operation… used up… considerable… magic power… but…… *haaa haaa*…… Seiji… -san’s… magic power… is enormous.」
「Is that so!?」
When I confirmed it myself, the MP had been decreased by about 100.
It wasn’t a big deal for me. But for other people, 100 MP was a fair amount.
「How did you learn how to use【Magic power reinforcement】?」
「I think… you can learn how to use it… with a little practice of【Body reinforcement magic】.」
「Is that so? Then, I’ll try to practice it.」
「Huh!? Is it possible that you can also use【Body reinforcement magic】?」
「Ah…… yeah, that’s right.」
Oops, I unintentionally made a slip of the tongue.
「Nothing, it really makes one jealous……」
「Please, keep it a secret.」
「Yes!」
Oh, he seems to be a serious person, it would be fine.
「So, this【Ice reinforcement magic stone】…… will you let me buy it?」
「No need to buy it, because Kisari-san taught me how to create it, it’s yours.」
「Such… usually, the work of channeling【Ice magic】receives a fair amount of money, so it won’t do.」
「Then in exchange, can I have some interesting magic stone?」
「I see. Suited for Seiji-san, right?」
Kiseri-san brought a magic stone with strange shape from the back.
「How about this?」
「It’s a strange magic stone.」
The magic stone’s shape is like a『Bottle gourd』.
「This is called【Twin magic stone】, it was recently unearthed and a rare magic stone to some extent.」
「About this【Twin magic stone】, can this be separated into two and combined into one?」
「Yes.」
Kiseri-san showed me how to detached the two attaching【Twin magic stone】.
「In this way, it can be separated into two and they will stick together like a little while ago when you brought them close to each other.」
「Just stick together?」
「No no! Well, please wait here with it one of the pair.」
Kiseri-san said so and gave me one of the magic stones, and moved to a slightly remote position.
「Well then, I will now make the【Twin magic stone】vibrate.」
*Tap tap*
As Kiseri-san tapped the【Twin magic stone】he held―
The【Twin magic stone】counterpart I held was similarly vibrating.
「Oh!? It’s vibrating.」
「That’s right, this【Twin magic stone】transmits a vibration to its counterpart. No matter how far, the counterpart magic stone will also vibrate in the same way.」
「I seen, it’s an interesting magic stone.」
「Well, because it only does that, it’s not that useful. Recently, it became popular by making two pendants with this magic stone and lovers wear it to ascertain their love with each other.」
「That’s wonderful.」
「I don’t know if it could be of help to you but how about it?」
「Okay!! This is good!! I want more of this, do you have more?」
「I’m sorry, there’s only this one set currently. The people who dig out magic stones have been borrowed for war. I think it would be difficult until the war is over.」
「Is that so? When the war is over, can you procure this for me?」
「Yes, I understand! I’ll procure it.」
I shook hands with Kiseri-san and left the shop.
「Oniichan, why do you want to obtain too many【Twin magic stone】? To make a harem and have them wear【Twin magic stone】pendants each?」
「Well, look.」
I took out paper cups and Sellotape from the inventory. I attached each part of【Twin magic stone】at the bottom of the paper cup one at a time.
「Elena, hold this.」
「Y-, yes.」
I distance myself a little and talk in the paper cup.
『Hello, Elena. Do you hear me?』
At the other side, Elena was surprised.
『Seiji-sama, I can hear you! How did this happen?』
『Because sounds produce vibrations in the air. It’s possible to transmit vibrations at a distance using【Twin magic stone】.』
『I-, It’s amazing!!』
Now then, what should I use this unexpected product for?~
