Magicraft Meister Part 3

Nothing more happened that night.

However, Jin had made a secret move.

"My Lord, who is the Quinta in the Shoro Kingdom?

<.

"Good. Can this be involved in the sabotage investigation?"

<

"Okay, then, please."

Having done what he could, Jin went back to sleep.

He was not in a tent, but in a .

The air-conditioning was working, so it was comfortable.

The next day, the 19th, Jin, Elsa, and the Minister of Magical Technology left the mine in Trom and returned to the construction site.

Just in case, <> is still in the mine.

"Well, the construction has been delayed for about half a day..."

Jin interjects,

"No, we've already finished leveling the ground and laying the foundation.

The Minister of Magic and Technology argued correctly.

"Then I guess you can leave it to us now.

"Is that so?"

Surely, Jin thought, I should leave my help to this point.

"In that case, I think I will go to Mitsuho.

"To Mitsuho, sir?

Yes. <

Jin glanced at the landing and said.

"We can use it to pave the promenade in the memorial hall, and we also want to use it to pave the airfield."

Asphalt is not produced on Horai Island. Arus has coal, but not much oil. The amount of coal is not so large either.

Therefore, the common pavement is <, which is reinforced by engineering magic such as .

However, the current macadam pavements may not be able to withstand the heavy loads of vehicles and aircrafts in the future.

"If we had engineering magic, perhaps it would be easier to repair asphalt pavements," Jin thinks.

Jin thinks.

The major drawback of asphalt pavements in the modern world is that they cannot be repaired properly.

When a hole is made, a new asphalt material is used to fill in the hole, but it has little affinity with its surroundings, and it sticks out or pushes in, making the pavement look uncomfortable.

"But be careful about covering a large area, because it will not allow water to permeate through."

It might be a good idea in a region with little rainfall, Jin thought to himself.

"Anyway, ensuring water permeability will be an issue for the future."

Asphalt pavement is 90 percent gravel, and the remaining 10 percent is asphalt in the original sense of the word. In other words, gravel bound with asphalt is asphalt pavement.

By using gravel with a large grain size and a certain degree of uniformity, gaps are created between the gravel, and as a result, the gaps remain after paving with asphalt, making the asphalt pavement permeable.

This is the outline of permeable asphalt pavement.

The disadvantage is that sand and mud clog the voids and drainage becomes poor in a few years, so it is necessary to clean the gaps.

In the afternoon of the same day, Jin and Elsa left the Shoro Kingdom in a and headed for Mitsuho.

"Is it difficult to pave a simple pavement ...... by pouring asphalt on top of macadam pavement?"

On the way, Jin is discussing with the old man.

"Now we have to see if we can improve the asphalt in Mitsuho.

<> and > together, we can secure considerable strength.

"And then there's also <."

Stabilization is an engineering magic developed by Stearina that makes it difficult for the molecular structure of a substance to change.

Specifically, water-soluble substances become insoluble in water, and solids are less likely to be broken down by ultraviolet rays.

One of the weak points of asphalt pavement is its durability, which can be improved by using this kind of engineering magic.

"The only problem is that only a limited number of people can use it. ......"

Jin thought that it might be necessary to make a golem for construction in the future.

Then Erza called out to him.

"Brother Jin, if you think too much, you will get lost, I think."

"What?"

Jin can do a lot of things. But that's why you have so many choices. That's why he sometimes thinks too much.

"Maybe so. ......"

Jin reflected a little that he had been thinking too much on the way to buy asphalt.

"It's been a while since I've visited Mitsuho."

"Hmm."

Unlike before, Jin did not have any connections to Mitsuho.

First, he heads for the town of Seki, as is customary.

"Probably Seki, right? ......"

The town of Seki is associated with Shuki Tsezi, who was Japanese, and thus has many place names that may be based on Japanese words.

In the town of Seki, a large airfield had been built.

"Oh, it's quite different from the old days," he said.

"It must be because of the increase in the number of flying machines," Reiko says.

Reiko said.

"I guess so. A horse-drawn carriage is fine from Shoro, but from far away, ...... a horse-drawn carriage or a golem car is necessary to carry heavy loads, isn't it?"

"Yes, that's right. Let's ask the old man about the main products of Mitsuho now.

Reiko uses the built-in manacam to inquire the old man, and he replies in less than a second.

"Bonito flakes, wood paper, asphalt, soap, cotton, wood crafts, and coal," he says.

"Not much has changed, has it? But coal?

"Yes. They don't burn it for heat, but use it as a kind of reagent.

"So that's what it is."

Jin thought that if he asked Saki, she might be able to tell him exactly what it was used for,

"Okay. Thank you."

He thanked the old man and Reiko.

"Master, we will be over the town of Seki in a few minutes.

"Oh, I see."

At Hope's words, Jin looked out the window.

"Oh, so that's the airfield.

Below them was an airfield about two kilometers square.

< was slowly descending in altitude toward the airfield.
