Magic architecture

"Hey, Ars. Can I just say this?"

"What is it, Baito-nii?"

"Your hideout is really a piece of crap. It's like a prison, this."

　I was complained to by my brother, Baito-nii, who was supposed to officially help me with my work.

　Why do you care about the way my hideout is?

　But I don't know what to reply to that.

　Rather, I guess this place is really like a prison.

　My hideout was the building I built when I cultivated the forest.

　When I made this hideout, I didn't want to spend time and effort to make it in the forest away from my house, so I made it quickly using magic.

　However, if I built a building all at once, the magic would fail.

　So, I created each wall first and not the building itself.

　Three walls with a height of 5m and a length of 5m were erected vertically from the ground leveled in a U shape.

　Then, the other wall was made into a square shape with an arched entrance.

　Only the roof that is not in contact with the ground needed a time-consuming process of making bricks and stacking them on my own.

　So, the hideout I made was a cube-shaped, or tofu-shaped, crappy type of building, according to my older brother.

　By the way, the wall thickness is close to 2m.

　Therefore, it may not be wrong to say that it looks like a prison.

"... Don't blame me, my Baito-nii. I'm a man who learns every day, after all."

　Until now, only Valkyrie and the others used the hideout, so I didn't really care.

　However, it is certainly not good as it is.

　It wouldn't look good if I had a lot of land and a lot of prison-like buildings on it.

　In this way, because of a complaint from my brother, I set out to remodel the hideout.

　* * *

"First, should I try that method?"

　Aside from the hideout, there have been some interesting events around my architecture skills, methods, and new information found before.

　It was when I went out into the city with the peddler.

　There were no wooden buildings in the city we went to, most of them were brick buildings.

　And, in the city, the wall on the outer circumference is being expanded, and I always saw people involved in architecture somewhere around.

　The bricks I made are also being used in the city.

　Once I knew that, it was natural to be wondering how the wall was being created.

　The inn where my father and I stayed was newly built.

　It is intended for merchants, not workers who are doing expansion work, but it was recently made from the workers who were also working on the booming economy of the expansion work.

　I paid attention to the inn.

　The inn was not that big.

　There was a front door facing the road, but the width was not so wide, and it was a type of building that continued to the back instead of spreading to the sides.

　The building itself was a two-story building, and when you entered through the entrance, there was a reception counter, and a staircase next to it.

　On the first floor, the dining room, kitchen, and owner's living room was behind the counter.

　When you go up to the second floor, the rooms are lined up on one side of the corridor.

　There are 6 rooms, but each one is not that big.

　If you put a bed in there, the space in the room was so small that half of it would be gone.

　I was closely observing the inn where we stayed at that time.

　I didn't just look around.

　I investigated it using magical power.

　The method I used was to soak my kneaded magical power into the bricks used in the inn and spread it thinly throughout the building.

　Perhaps it was because I am familiar with the magical power of things in the soil system.

　My magical power soaked into the bricks without much effort, and I succeeded in sending the magical power to the entire building quickly.

　Then, in that state, my magic was activated.

　The magic I used was [Memory Preservation].

　I just happened to come up with that plan when I stayed at the inn and tried it.

　But this worked better than I expected.

　I succeeded in instantly remembering the shape of the entire building without any deviation.

　There is often a method of displaying a building layout using CGI on a computer, so that method may be close to that.

　The whole graphic view was being inputted into my brain.

　My brother may be surprised if I make this inn that I remember perfectly.

　With that in mind, I decided to conduct an inn reproduction experiment.

　* * *

　When I tried to make a building with magic for the first time, I fainted because all my magical power was gone.

　The lesson learned at that time was that the magical power consumption of a building depends not on the area or amount of building materials but on the space capacity.

　I don't think that theory is a mistake.

　However, this time I will break away from that hypothesis and build a building at once.

　The reason for this idea is related to the usage of my magical power and [Memory Preservation] to grasp the structure of the inn.

　Through using my magic to see what, how many, and where the bricks were in the inn, I completely remembered the building.

　Yes, at this time I can remember how much magical power I need according to the shape of the building, and not include the entire space.

　I think that when I tried to make the building I imagined in my brain the first time, I wasn't clearly aware of what the interior space was like.

　What I had in mind was what it would look like when looking at the building from the outside.

　I feel that this is the cause of wasting magical power.

　However, this time I remembered the whole thing, so I completely remember the internal structure from the stairs to the width of the counter.

　If so, if I use magic after reproducing the magical power in that form, I may not waste the magical power.

　With that in mind, I quietly kneaded my magical power and once poured it into the soil on the ground.

　I send magical power to the soil that will be used for the inn.

　Somehow, from my experience of using magic, I feel that there is a magical amount of things that can be built without wasting money.

　I hold my breath with a Suha.

　I concentrated my consciousness and continued to operate magical power.

　Previously, I had a hard time remembering the magic circle and using it myself.

　At that time, I thought it was difficult to reproduce the magic circle that I saw with my own eyes.

　But this time it's different.

　I remembered the building not by visual information but by magical power.

　All I have to do is reproduce the shape of the magical power I learned.

　The shape of the magical power is changed while keeping the structure of the inn.

　It takes time to reproduce it carefully, but without getting as tired as when trying to recreate the magic circle.

　I build a building with magical power without losing concentration until the end, and convert that magical power into a brick shape as the final finish.

"... I was able to do it. It was a success."

　In this way, I built an inn in a terrifying amount of time.

TLN: This chapter was a bit confusing, so let me clear things up. First of all, Ars' theory of how much magic is needed depends on the "space that the thing created takes up, both inside and outside" is considered to be true, according to Ars. However, Ars kind of thinks about that system like a default system on a website. You see, if you do not know how much you need to use, the space inside of something will also be counted in the creation, if the creation is hollow, such as a building. However, if you know exactly how much space you need inside using magic, then you can think up how much magic you need.

You see, Ars spread out his magic in the original inn to measure everything and to engrave everything into his mind perfectly. In doing so, he found out how much magic was needed to encompass the entire inn. Now, when creating the new inn, he can use that information to determine exactly how much magical power is needed to create the entirety of the inn.

Originally, when trying to build a building completely, he only thought about how much magic would be needed for the outside instead of also the inside. That is why when creating the building, the space inside was also accounted for. But after copying the exact ins and outs of the inn into his mind, Ars knows how much magic is needed. He can shape this magic to create bricks in the places he wants. Kind of like the dark mode on websites. The default is always light mode, and unless specified, it stays like that. Any more questions?
