"Even if the operational efficiency is high, it is meaningless if it cannot be mass-produced. ......"

Jin then decides to select a bio-based material that he has on hand and that is likely to store a large amount of mana.

His assistants were the old man and Reiko.

"Yes, the more powerful the demon is, the more likely it is to be so.

<> or <> would be a good choice.

"Yes. Let's try those two."

So Reiko brought out those two kinds of materials from the warehouse.

"Since they are not alive, I think they will store <> magical element (mana). ......"

<>.

Anyway, the first step is to conduct a verification experiment.

"I think size is more important than weight."

Jin decides to see which one can store more mana in the same volume.

"Father, in this case, you are prioritizing volume over weight, right?"

"Yes. Yes. It's a matter of how compact we can make it.

Jin separates the two types of materials by .

He cut them into dice about 1 cm square.

The reason for the cube shape is to increase the filling rate.

"Hmmm, how to fill it with mana?

Jin thought it would be better to do it in a practical way, so he quickly prepared a standard type of <>.

"Okay, let's run this for a certain period of time and see what happens.

Jin wanted to find out which one would store more mana by giving it more than enough mana.

"Father, your research is fine, but it's time for you to go to sleep.

"What?　Oh, is it that late already?

It was already 10:00 p.m. when he came to.

"Okay. We'll continue tomorrow."

Jin obediently followed Reiko's advice and decided to take a rest to recover his energy.

The next day, Jin went to bed in the morning.

The next day, as soon as Jin finished breakfast, he conducted the verification he had thought of the day before.

As a result, he found that the gigantopod material stored about 20% more.

"The weight is almost the same," he said.

The specific gravity of both materials was around 1.

"So, how much can it store?"

Since there is no unit of measurement, this will be a comparative experiment, but in conclusion, it seems that the AAA type mana tank can store about 2.5 times as much mana as the previously standardized AAA type mana tank.

"This is practical enough, isn't it?"

Jin decided to make it cylindrical, like a battery, so that it would be easy to replace.

"The image I have in mind now is an AAA battery."

This is to differentiate it from the previous AAA type mana tank.

It was also found that the golems of Horai Island can operate for 24 hours on average when equipped with 10 mana tanks.

Of course, this is without using extremely violent movements or consuming magic during the operation.

"30 pieces of equipment, plus 2 for emergencies, I guess."

The emergency one is used for , for example, one for transfer to the sea surface in case of an accident in the deep sea and escape becomes impossible. And one to send a distress signal to Horai Island and to maintain the current situation.

"Also, I would like to have a supply ship standing by nearby, and have that ship carry a large amount of mana tanks and be able to recharge them.

Jin pondered and came up with an idea.

"I wish we could transfer energy.

He had learned from the science fiction novels and manga he had read in modern Japan that energy could be transferred to a remote location.

"I wish I could do that," he says.

The "Mere Old Man" had tried several experiments to see if it could be done by using a warp gate, but they did not work out.

A warp gate connects two points by a . The , which we tentatively call , passes through a space that is not real space, allowing travel between the two points with virtually no time loss.

This is all we know about how the warp gate works.

The next question was whether it is possible to exchange something other than objects by using the tunnel.

For example, to send water to an area with water shortage. Drainage of water from flooded areas. This was the next question.

The conclusion was that <>.

At the exit of the warp gate, the velocity of the object becomes zero. No matter whether the velocity at the entrance is fast or slow.

The reason why this happens has not been clarified, but for this reason, even if water is pumped into the warp gate, it simply overflows from the exit, and the momentum of the pumped water is not maintained.

"I suppose it is the same with free magical element (ether), although we cannot see it."

If the object has its own propulsive force, like an aircraft, it can immediately depart from the exit gate (warp gate).

Also, it seemed to me that if we pointed the outlet downwards, we could probably drain the water.

"But free magic element (ether), right?"

<<

"It seems so. The reason is unknown at this point.

<

"No, it can't be helped, the experiment was short."

Jin instructed the old man not to worry about it, and thought about it again.

"For the time being, we will have to communicate with them in the form of <> or <>. ......

Jin did not like the idea of sending them in this way and exchanging them for the right things, because it was very time-consuming and not very smart.

"But father, I don't have a choice, do I?"

"Yes, but I'm sure I can do something about it if I can just ...... find one more thing to spark it. ......"

<<

"Yes, there are priorities, aren't there? ...... hmm?　Yushin?　Yushin ...... wired, or ......"

<>

"My Lord, please experiment to see if you can connect the warp gate with a wire. I will make a mana cylinder.

The old man knew what to do just from Jin's short instructions and started the experiment with <> and the craftsman(smith)1.

<

First of all, we need one pair, that is, two warp gates. I prepared ordinary steel wires for them.

We activate the warp gates and confirm that they are connected from the entrance side to the exit side.

Then, I inserted the wire from the entrance side.

But nothing happened.

"...... still no luck."

The current warp gate is not designed to transfer <> of the body for safety reasons.

For example, it is not possible to transfer <> of a human being.

It can be said that the transfer is performed after confirming that <> is within the transfer range.

This <> is limited to solids, and liquids and gases are considered to have a certain range of tolerance.

This can be understood from the fact that the air around the object or person being transferred also transfers with it.

In other words, it is impossible that <>.

This is something that even the old man could not do anything about.

Then, Jin, who had finished making a prototype mana cylinder, came in.

"How do you like it, Mr. Mana?

<>

The old man explained the result of the experiment to Jin.

"Well, I guess so. ......".

From the results, we can guess why it did not work.

Jin realized that he had to change his mind that this method of energy transfer was unlikely to work.

If the object has its own propulsion, such as an aircraft, it can immediately depart from the warp gate on the exit side.

It also seemed that if the exit was facing downwards, water would probably be able to drip out of it.

"But what about free magic element (ether)?

"It seems so. The reason is unknown at this point.

Then, he inserted the wire from the entrance side.

If Jin's prediction is correct, the wire should come out from the exit side.

And it succeeded with flying colors.

If the iron wire goes through, the next step is the mithril conductor.

Mithril could be passed from the entrance side to the exit side in the same way.

<

The old man connects an ether tank to the exit side of the mithril line.

<

And the experiment starts.

The old man was almost sure of success.

>

However, contrary to his expectation, the free magic element (ether) did not flow.

<>

<

The "Mere Old Man" was at a loss, not knowing what was wrong.

Then Jin, who had finished making a prototype mana cylinder, came in.

"How do you like it, Mr. Mana?

<>

The old man explained the result of the experiment to Jin.

"Well, I wonder why?"

Jin also twisted his head.

"My Lord, let's leave aside for the moment the question of why we can't send free ether or mana, and let's try one more experiment.

>

"Instead of wires, I'd like to run a pipe through it and see if it's possible to pass water or air through it.

.

The "Mere Old Man" immediately started the experiment.
