Early in the morning of the 27th, the fully equipped departed three hours behind schedule.

The first thing to do was to transfer to the <.

Adriana, with a diameter of 300 meters, could not make the transfer, but Vulcan, with a diameter of 100 meters, could.

has traveled 212 million kilometers in one stroke. All that remains is the flight to the <>.

However, it is about 75 million kilometers long, so even if we fly at 300 kilometers per second It would take 70 hours even if we fly at 300 kilometers per second.

However, this is where the new equipment that Jin has been working on, even delaying his schedule by three hours, comes into its own.

The new equipment is the .

When an object in the forward direction is captured, it is shifted to the rear.

The effects range from cosmic dust to micrometeorites. Large obstacles are to be avoided visually, but small collisions that could not be prevented by the previous can be nullified in a shorter time than before.

This is largely due to the improved reaction time.

The upper limit of the flight speed is determined by taking into account the inevitable collisions with cosmic dust and micrometeorites, and consequently the upper limit depends on the reaction speed of the boundary.

It is now possible to more than double the limit, to 800 km/second.

In other words, we can reach the in a little over a day.

"Tomorrow, Aethenol will arrive from Vulcan.

>

The old man takes Jin's intentions into account and begins to move quickly.

Aethenol itself is not toxic, and there is no danger of explosion. Therefore, an ordinary water tank is sufficient.

There are many holes in the ground where the ore was mined. Most of them are backfilled with tailings, but some of them are used as warehouses or farms for <><>.

In modern Japan, water tanks have been installed here and there for disaster relief, ranging from 60 cubic meters to 1500 cubic meters. The tanks vary from 60 cubic meters to 1500 cubic meters.

Mr. Lao decided to construct 10 tanks of 100 cubic meters each.

The tanks are made of 18-8 stainless steel and the inside is plated with mithril silver to prevent oxidation and deterioration.

One tank will be completed at the same time as the ethenol is delivered, and the number of tanks will be added one after another.

"At the same time, it's a generator of ......"

There is much work to be done, Jin said as he began his work.

This continued until Erza called for him at lunch time.

"Is Elsa OK with her hyperemesis already?"

Jin asked Elsa, who was eating a sandwich with him.

"No, I'm fine now," she said.

"I'm also relieved that it's only a little bit worse."

Meane, Erza's mother, answered. Meane told us that her hyperemesis gravidarum had been light as well.

On the other hand, Marlene, Elsa's foster mother, had a severe case.

"Don't overdo it. Don't get cold.

I'll be fine.

"Don't worry, Jin-sama, I'll be with you. Jin-sama, please do your work as you please.

Thank you very much. And please don't call me "sir" anymore.

I don't think so.

Ever since Erza had a child, Jin has repeatedly asked Meane to stop using , but Meane stubbornly refuses to listen to him.

She barely sits at the table with him and eats with him.

But she is going to be the < of my unborn child, and it's not good for her education if she stays like this forever.

Finally, Jin played his trump card.

"Well, that's certainly true. ...... I'll try my best. ...... Jin, sir."

It seems that he could not resist the fact that he was going to have a grandchild.

* * * *

After lunch, Jin went back to the workshop.

In the morning, the main components such as the link board, the link core, and the operational core had been completed.

"These parts are common.

The size is also small. What is different is the <. This is, for example, an antenna.

The <> is the part that activates the effect of a complexly conceived system.

It consumes less mana than an all-in-one system, so it is especially effective to make it separately in the case of a huge system like this one.

In addition, in this case, we want to increase the reaction speed of the sensor to activate the device to the utmost limit.

"First, let's install it in Horai Island, and then in Kaina Village.

.

If the scale of the warding is that large, we can cover it with the ethenol we have now.

Jin carefully assembled the two units, reviewed them three times, and then instructed the old man to install one of them at the top of Mount Horai.

"Oh, we're going to test the operation, so you don't have to install the other one, just take it with you."

.

Lao Tzu himself took control of the Raptor 2 and headed for Mount Horai.

Two minutes later, he was informed that the preparations were complete.

"Okay, the one for Horai Island is on the way. Start the test run.

Almost at the same time as those words, a huge magic circle was deployed in the sky above Mount Horai. Its diameter is about 100 kilometers.

"It worked."

The other one was also tested successfully.

"Okay, let's set one up at Nidou Castle in Kaina Village. I'll take that one."

The top of the castle tower would be good, Jin said.

Thus, the was installed on Horai Island and in the village of Kaina.

Incidentally, I would like to add that the 100-kilometer-diameter wards would include the village of Toka, where Licia is located, in their area of effect.

At the same time, the amount of ethenol consumed was also estimated.

"One 100-meter-diameter field, generated for one second, consumes 0.1 liter of ethenol. I see."

Since the amount consumed is proportional to the area, a sphere covering Ars would consume 63,700 liters per second.

The weight is nearly 64 tons.

It is a tremendous amount, but not so much that it is unmanageable.

The "Mere Old Man" is currently building a tank that can store 100 cubic meters, or 100 tons of ethenol. The problem is that Ars is oscillating in space.

The question is whether the preparations will be completed before Ars is hit by the spatial oscillation.

Jin renewed his determination to do all he could.

* * * * *

Jin then installed a generator on and on all the spaceships.

And just like that, the current stock of Aethenol is empty.

But...

<

More than we have consumed so far. That's good news.

You are early.

<

Indeed.

Using a free-magic condenser (ether capacitor), it is possible to produce Aethenol even with normal concentration of free-magic element (ether).

In other words, <> is flying while producing aethenol.

Jin felt that he had a glimmer of hope for the future.
