The school went on winter break and came back to my parents' house, but I didn't have much to do, so I took Flora to hang out in town.

"Flora, what do you want me to do?

"I don't know what's wrong with it."

"That's right. I think I'll take a peek at some store.

As we walked in thinking about which store to enter, Sheila would stop herself when we passed in front of the dining room where we used to take care of her.

"Ah! To Ray, Flora, you've come to the right place. Come here."

"What is it?. Let's go to Sheila's dining room.

"Aye!"

As soon as I went to the dining room, they took me to the manager's office at the back entrance.

"Ray, I need to talk to you about the [smooth pudding] you made me at the end of my work experience before...

"... that's it.

"I knew I couldn't reproduce it even if I made it according to the recipe I received... Can you just tell me how to make it again?

(What to do...... It's hard to say the result of the skill that [the extreme of the material], but I don't think it can be deluded...

"Sheila, would you mind keeping my parents informed about the pudding as well...?

"... I'm afraid to ask you something, but I'll keep it to myself.

"Will you keep Flora a secret, too?

"Okay! Can't you just flinch at it?"

"Okay, I'll tell you what. The fact that the pudding was so delicious is simply affecting my skills. I can't tell you the details on the boulder, but when I make it, it tastes better than usual, so I can't reproduce it even if I make it according to the recipe... I think I fooled you, I'm sorry.

"That's another strange skill......

"So I'm going to fly, but in six months, even in a city with a school, I'm going to open a shop that sells sweets in collaboration with someone I know, and that's where I'm going to hide who I am and make sweets.

"Hmm? What are you talking about?

"I'm the only one who can make pudding, so I can't make it here, but I was wondering if I'd be able to wholesale the confectionery from the confectionery shop that opens over there on a regular basis.

"I see. Then we can sell sweets in our cafeteria if the quantity is limited. What about the shelf life? If you're transporting it, it's tough when it doesn't work right away.

"I'm currently developing a box for transport and I think I can save it for a week if I put it in that dedicated box.

"Then I'd love to.

"The store will open around summer by appointment, so I'll contact you when I get home when the opening date is set.

With the recent mass production of [Rainbow Demon Stone], various experiments can be carried out. As a result, [Rainbow Demon Stone] can be used to grant [storage] to boxes, and [Rainbow Demon Stone] can be conceived as a normal demon stone.

It is difficult to use [Magic Instrument] of [Rainbow Demon Stone] without replenishing it with [Magic Instruction Operation], but it can be very convenient to use the time stop function when transporting it.

You can't sell [Rainbow Demon Stone] as a [Demon Stone] because it makes a scene. For this reason, you wanted to disguise the box type [Storage] as a cold box that uses the [Demon Stone] attribute of ice.

So I thought, the solution is to first make [Rainbow Demon Stone] the size of the limit at which the function can be maintained, and then cover it with normal [Demon Stone] around it.

The only way to cover it with ordinary [Demon Stone] is to bias [Rainbow Demon Powder], the ingredient of [Rainbow Demon Stone], into the attribute you want to disguise and turn it into a special [Demon Stone].

It's a hassle, it's more laborious but this is the successful disguise so far.

In the future, I feel that it would be possible to solve it if I made a [magic guide] for disguise, but I have yet to succeed.

The disguise method was made of simple machine improvements, but because there are machines dedicated only to the portion of attributes that I want to disguise, the basement has more capsules that make 12 more disguises [Demon Stones], making the lab even more chaotic...

But this disguise [Demon Stone] is excellent and deceives his [Appraisal] and appears as a normal [Demon Stone], but the effect is [Rainbow Demon Stone].

The only drawback is that when the [Rainbow Demon Stone] is small, the performance also falls, so the [Demon Stone] after disguise is larger than normal around 2 [Demon Stone] in order to give the required performance.

That area will be a future research challenge......
