Now that we had the prospect of procuring the most problematic water pipes, the rest of the conversation proceeded smoothly.
"We can start with a small water purification plant and then increase the number of the same plant, right?"
"Yes, that's right. Parallel processing will work.
Jin thought that it would not be possible to install a large one at once, but the members of the family seemed to agree with him.
"Then there is the water source."
Jin had been thinking about this for some time.
"It would be against the slope, but we could install a water purifier on the seashore and use a pump to send the water inland.
"I see. That's why they called it a water pump.
Even in modern Japanese mountain lodges, there are places where water is pumped up from a stream to the top of a ridge.
When pumping water up, it can only be sucked up at one atmospheric pressure, but there is no such limitation when pushing water up. It depends on the strength of the hose or pipe and the pump.
Of course, there must be enough power to operate it.
"A pump could probably be done with a magic circle, so the cost could be lowered.
"Yes, I think so."
"Cost is a big issue, girl."
Elsa and Hannah were also concerned about the cost.

The discussion was almost over and Jin started to summarize.
"Well then, we'll build a water purification plant on the seashore, and then pipe it inland with bamboo pipes.
"Yes, that would work. We can use ...... to build intermediate reservoirs about every kilometer to hold the water."
Reinhardt adds.
"The water in the reservoirs can also be used for irrigation, right?"
Hannah says to make sure.
"That's right. The reservoir will be equipped with a magic circle for water purification. The pumps are magic circle type and always deliver a constant amount of water. Of course, it can be stopped."
Jin wonders if it would be better to work with <> or with Jin and Makina.
"Jin and Makina, that means Horaijima will take the lead. I think it would be easier to manage the schedule that way.
Erza insisted that it would be better to have the meeting at Horaijima.
"Yes, I think so too. should have a different aid."
Saki seemed to agree with Erza's opinion.
"Then what about the price, Jin?"
Marcia cautioned.
"You always overdo it, Jin."
"U...... can't argue with that."
At Marcia's suggestion, Jin thought about what he would ask for in return for this job.
"I don't need money. We have enough food. We have ...... and then what else?"
Rodrigo was the first to speak up.
"What about sharing the soil?"
"It's fertile soil, so we can use it. ......"
Moreover, it seemed that if they limited themselves to the soil from the reservoirs and water pipes, there would be little impact on the area of arable land in the future.
"But they say that's probably too cheap."
"Well, hey ......"
There is nothing more in the Principality that Jin wants. It should be .......
"Do you have any interesting plants, Saki?"
"Hmph, you shake your head at me there. I can tell you that there are ...... some interesting plants.
What's that?
It's a weed that grows in the wasteland, but it seems to be a transplant from Hale.
"Hmmm, that's true. I just discovered it the other day with my peepers, and I haven't even seen the real thing yet.
Saki scratched his head.
"But it is a useful plant. It seems to be making high purity hydrocarbons inside the plant."
"Hydrocarbons ......?"
Hydrocarbons are compounds of carbon and hydrogen. Simple ones are CH4, methane. Polyethylene is represented as (C2H4)n.
It is a gas when the carbon C is small, and becomes a liquid when C becomes 5 pentanes.
Propane gas and benzene are also hydrocarbons.
"It's ethylene, honey."
Hannah explained.
Ethylene is C2H4.
It belongs to a group of hydrocarbons called alkenes, which are also plant hormones.
For example, it is said that ethylene inhibits potato sprouting.
"So it's made of polyethylene."
"That's what I mean."
"And it has a high content of <>!"
Hannah said that it might be because <> brought it from Hale.
If so, it is worth stockpiling in Horai Island as a material or raw material.
Magi polyethylene is made by replacing carbon and hydrogen with magical isotopes (magi isotope) carbon and hydrogen.
Until now, magi resin has been processed, but if the plant can be used, it should be possible to further mass-produce it.
The advantage of Magi-Polyethylene is that it is much more weather resistant and degradable than ordinary polyethylene.
These seemingly contradictory properties are the interesting point of Magi materials. In other words, if the bonding force by the free magic element (ether) is strengthened, the weather resistance is increased, and if it is weakened, it easily decomposes and returns to the soil.
"It's nice that it doesn't cause environmental pollution."
Like regular polyethylene, it is also highly resistant to solvents. Since it does not contain water, it can be used as a coating material for ships.
"If we impregnate <> with this, we could make something even better: ......."
Jin mentions this idea, but Saki denies it.
"Oh, I guess the cost won't be competitive for the time being.
"I see, too bad."
"Well, we still want to lower the cost in the future.
If the demand increases, the cost will decrease, but for now, the material is almost exclusively used in Horai Island, so the demand in that sense was zero.
"But don't you think it's strange that they want grass that they think is a weed?"
"Ah."
Marcia's words made Saki and Hannah look at each other as if they hadn't thought of that.
"......Well, we could take the grass, but in the end it would be too cheap a price to pay."
Jin laughed.
"It's hard to say what the price is, isn't it?"
"......Totally."
All the members of the present at the meeting agreed.
"It's not exactly underground resources, is it?
They will be essential for the future development of the principality, Jin said.
"Speaking of resources, ......"
Hannah started, "This is a little off topic," she said.
"By the way, since you're here, I think you should check out the underground resources of the four duchies, don't you?
"Yes. It would be good to have the data.
Jin agreed with this opinion.
Thus, the data on the distribution of underground resources in the four countries was completed.
