Beyond the back door was a small room.

It looked like an office and was very dusty. This room had probably never been cleaned.

There was a desk in the middle of the room, and in front of the desk was an automaton sitting on the floor.

"Wait a little and it will start to move."

<

"Is it in a sleep state due to lack of free magic element (ether)? ......"

The golems and automata that Jin has created have an auxiliary , so they do not stop suddenly.

They should stop after taking measures to maintain their own condition as much as possible. Of course, at that time, they should contact Horai Island by manacam.

As Jin was thinking about this, Elsa, Edgar, and Mii arrived.

"Brother Jin, what is this place?　Where is this automata?

"Ah, Erza. This automaton is probably the factory manager. I think she was in charge of this whole factory.

Mii's eyes widened.

"That's amazing!　No one has ever been this deep before!"

"Well, why is that?　Well, there's nothing we can do to fix it.

As we were exchanging these words, finally started to move.

"...... have I stopped ......?"

Then he finds Jin and greets him.

"Welcome. I am the factory manager. What can I get for you today?

Hearing this line, Jin was convinced that he used to give orders to the factory manager, and the factory would produce accordingly.

"No, it's not an order today. As you just said yourself, the factory was shut down until just now. You should be aware of that first."

The factory manager responded to Jin's explanation in the proper way.

"Oh, I see. Then we must start by reorganizing the factory.

Hearing this, Jin felt a little relieved that he could have a decent conversation with the factory manager.

"No, we should wait for that too. In the current world, the concentration of free magical element (ether) is so low that the factory cannot operate properly.

"That's a problem. What should we do?

The factory manager seemed to be at a loss, as he had not expected such a situation.

At this point, Jin decided to take a gamble. It was a gamble with a good chance of winning, however.

"How are the materials coming in?

"Yes, using the first, second, and third warp gates, but if the concentration of free magical element (ether) is decreasing, it seems to have stopped."

"That's right."

Jin was relieved. After all, this factory was using a warp gate to bring in materials.

<'s location, he wondered if this was the case.

The bet was that if the technology was still in use, Jin's use of the warp gate would be acceptable.

Jin wanted to bring this factory to full operation.

It was too bad to leave this factory, which had many things that Jin did not have or had not developed, to rot away.

However, there are too many Golems for Jin to go around repairing them by himself. But...

"Factory manager, how do you maintain and repair the Golems here?

Yes, they have been in operation for a long time, so they must have a maintenance system in place.

Yes, we have 50 golems for maintenance.

Jin was right.

"Where are they?

Yes, in the room to the left, once you leave this room.

Okay.

Jin asked Mii, Erza, and Edgar to stay there and keep an eye on the factory manager, while he and Reiko went to check on the maintenance golem.

"...... this?"

As the factory manager said, there were 50 maintenance golems lying on the floor.

"Reiko, get me 100 Magi Crystals......, of below average quality, and contact the old man to have them transferred here."

"Yes, Father."

Reiko's bracelet could be used to make such a call, but since it was built into Reiko's bracelet, such a call could be made in a matter of seconds. And since he does not have to say it out loud, Jin often asks Reiko to do so.

Of course, it is also a sign of his dependence on Reiko, and Reiko is in a particularly good mood after performing such an errand.

In less than a minute, 100 Magi Crystals appeared in front of Jin and the others.

"Okay, we'll use these to make an ether converter and a mana driver. We'll implant them into the golem for maintenance.

"Yes, I will help you."

Immediately Jin started to make an ether converter and a mana driver corresponding to the current concentration of free magic element (ether).

Reiko exchanged them one by one with the old equipment of the maintenance golem.

Erza's education seems to be working to some extent, as she is thinking in the corner of her mind that if the mine is restarted, she will be able to replenish what she used today .......

After replacing about 10 golems, Jin stopped his work and restarted the golem for maintenance. This time, since he had replaced the energy generators, he needed to < them.

Unlike the rebooting at the time of replacing the control core, the rebooting at the time of replacing the ether converter and the mana driver does not require any keywords.

What are your instructions?

I'll try to activate one first. Reiko is on alert just in case, but there seems to be no danger.

"The ether converter and mana driver are malfunctioning. Do you understand?

I understand.

He seems to have enough knowledge and skill to maintain the golem. Jin wondered if this meant that they were becoming more specialized and specialized.

"Okay. I have prepared an ether converter and a mana driver here. Work with the other nine and refurbish the remaining forty.

Yes, sir.

The nine units that have already been exchanged are reactivated, and the finished ether converter and mana driver are handed over to the ten maintenance golems, who proceed with their work quickly and efficiently.

Although not as fast as Jin's work speed, it is still fast enough.

"When you're done, you can help each other maintain your bodies, and then stand by. Then we wait."

Jin gave the order and left the room, thinking that this would take about two hours.

"Ah, Jin-sama, how was it?"

Mii asked when Jin returned.

"Yes, the maintenance golem will be complete by the end of the day. After that, we'll see what happens tomorrow.

Mii was moved to tears when she heard this.

"Really?　...... Oh, it's Jin-sama after all!　Thank you!"

"No, I hope I didn't mess with it without your permission..."

Thinking about it calmly, Jin felt that he had done something quite arbitrary.

"Don't worry!　I was with him, and there was nothing wrong with it!　If anyone complains, I'll complain too!

Jin let his words sink in and confirmed one more thing that was bothering him.

"...... Factory manager, where is the warp gate for bringing in materials?"

"Yes. It's just outside this room, opposite the maintenance golem.

Okay.

Now we all headed for that room.

"......Oh, that's definitely a warp gate.

It may look a little old-fashioned, but there was definitely a warp gate there.

"...... but it hasn't stopped."

"What?"

Erza is still a novice when it comes to warp gates. She still doesn't understand what Jin has found out.

"See, the magic circle ...... inside the Warp Gate is emitting a faint glow, isn't it?　That's the evidence that it's on standby. So don't step in it by accident, okay?"

"Uh-huh."

Erza, who had once stepped into the warp gate of Horai Island and almost got lost, though it was an accident, nodded her head mysteriously.

"But why?　The golem had stopped moving.

"Oh, I think it's because the ether converter and mana driver in the Warp Gate are specially made."

Jin cites the fact that the warp gate to <> was working, and that Akitsu was also working, albeit unsteadily.

"So you are saying that even old things can somehow work if they are well made?

"That's right.

However, it is too risky to go and check what is on the other side of this warp gate by ourselves.

Therefore, we decided to throw a <> into the warp gate, and use the <> and > to locate its position.

Reiko moved to a little distance and received the <> from the old man. Now we can proceed with the work without Mii's knowledge.

"Let's see if it really works," she said.

With these words, he throws a , which looks like a stone, into the warp gate. It disappeared in an instant.

"It's gone!

Mii is surprised. Jin throws the same marker into the remaining two warp gates, and confirms that they disappear as well.

The warp gates are still alive after all. Then, it must be a trouble on the other side that the materials have not been sent. There is no more time today. Let's get ready and come back tomorrow.

The next thing I knew, it was almost 5 o'clock.

Jin and the others left the factory and returned to the town of Miyako.
