"Safety check, all the sources?

'Oh. That's everything except the stash room. Let's see where we can see it, even in the hidden room.'

'... How wide is this source?

"If you include a fine path or something, don't make it a total extension and close to a hundred kilometers. If you walk and explore properly, it won't be a day or two '

The source is the giant equipment of ancient civilization.

Most of them will not be functional by now, but it is not strange that the road remains quite a bit.

That's why it's so hard to find out you're diving in like this.

If the source is not a very large facility, the Demons must have planted detective magic props on all roads.

If that were the case, the time taken to investigate would not have been like this.

'... could you walk and explore?

'I might do that if the room I'm going to now doesn't help... but I probably don't have to worry about it'

That's how I put magic through the nearby walls.

Then the wall that was nearby disappeared... from inside, a very small hidden room appeared.

It's more or less two meters wide.

"Hidden room?

"Oh. It's so narrow, but it'll probably help."

Since the source is a very large but important facility, there are many hidden rooms inside.

Some "official hidden rooms" were written from the beginning in the blueprints, while others "informal hidden rooms" were created on their own by humans involved in the production of the source, like me.

This hidden room is the latter... or the hidden room I've been sneaking around in.

Its function is' monitoring inside the source '.

As well as the normal compartment of the source, this room has a device that allows everyone to monitor all the hidden rooms that were there at the time of construction without anyone noticing.

Some of the stash rooms at the sixth source were made without my knowledge, but I also found them and kept them under surveillance to make it easier to deal with them when the source was used for crimes, etc.

Well, being able to monitor all the hidden rooms assumes that there are no hidden rooms that were well disguised enough to deceive my eyes at the time.

With that in mind, I undo the door and activate the magic props inside.

When this is broken, it's a lot harder to do...

"All right, you're alive."

Apparently, the magic props are working properly for me.

Shortly after the launch, the walls of the concealed room showed the figure of seven people inside the sixth source and footage of the place.

"I knew you were here."

That said, I'm referring to a medium-sized stash room, located directly below the warehouse where the masked man procured the poison.

There was a poison conditioning facility there that took life, and inside, three demons were conditioning the poison.

'You were really formulating in the source... Why are you making it in such an easy place to find it?

'No, this place is rather hard to find. Hidden rooms can't be found unless they're special magic, and even if someone were to explore the origin of the poison, it's easy to overlook them as candidates in the source.... it looks like the poison is being transported from the outside.'

'I was wondering why you carry it in a luggage car or something when you're making poison in the source... is that a mislead in the origin of the drug...'

'Oh.... there seems to be a reason, simply, that the hidden room at the source is ideal for a safe house'

This time I was found hiding in the source for only one reason.

That's because I already knew there was a hidden room at the source.

If I had no knowledge of the source, it would have been impossible to find the Demons.

It's 100% impossible to discover a hidden room, although we could have noticed enough from the surrounding circumstances that maybe the enemy was inside the source.

The heritage of ancient ruins works that much if you know how to use them.

That's why, if a human being who knows how to handle it has turned to his enemies, it's dangerous.

'... so we're raiding this room, right?

'Oh. Don't be.... but this demon, why are you in a place like this...?

That's what I say, I observe the demons reflected on the walls of the room.

What you see there was a demon tribe that wasn't supposed to be here.

"Is this demon race unusual? You look like a normal demon clan... '

"Oh. Unusual.... or if this guy's who I expected him to be, he's not supposed to be here. '

That's what I whine about as I see the demons reflected on the walls.

"The Demons who aren't supposed to be here?

"Oh. I'm not strong enough."

Among the demons, there are different races.

The 'Misty Demons' and 'Subdemons' we've fought before are one of them.

And the type of Demon Nation shown now is' The Demon Nation of the Earth '.

It is a species that has no great distinctiveness except that it is sturdy, fast escaping, and relatively easy to create a herd among the Demons… "The Demons of the Earth" is a species that should have perished.

"The Devil Nation of the Earth" boasted a great force in the past due to its ruggedness and the nature of making herds, making it a great threat.

And thousands of years ago, there was a great war between the demons of the three races, including the 'earthly demons', and man, and as a result, the 'earthly demons' were utterly destroyed.

Their demise was confirmed using state-of-the-art detection techniques at the time.

I myself confirmed doom by using detective magic that would penetrate even cover-ups, or magic that would find very few traces from all over the world.

That its extinction determination is incorrect cannot be the first.

Yet here is the 'earthly demon tribe'.

... There was no such thing as the magic of resurrecting an extinct species in previous generations.

There wasn't even magic in the magic I studied that would make that possible, or even a clue to resurrection of the dead.

The only magic that is close to resuscitating the dead is the reincarnation magic I used in my previous life.

But only human personality can be reincarnated with that magic. It is impossible for a reincarnated body to have the body of a 'earthly demon tribe'.

'It's a rare demon race... But you're not a strong demon!

That's what Alma said when she heard me.

... For now, will we put behind us the reason why the 'Devil of the Earth' is alive and defeat the Devil Clan?

"I'm not strong, but I'm hard and fast on the run. When I'm going to defeat all three of them properly, I need to block my way out."

With that said, I'm leaving the room where I have my surveillance magic props and heading to the hidden room where my enemies are located.

In a hidden room with enemies, there is no surveillance equipment like the one we were in earlier.

Since the walls of the concealed room are made of material that blocks magic, the situation is not explored from the magic reaction.

So the enemy will have no idea what we're doing.

Let's create an attitude where our enemies can't escape right now.

'In the meantime, Ilis is here, Alma is here to stand'

That's what I'm gonna tell you. I'm gonna show you two the placement.

The Iris stands just in front of the exit, and Alma is a short distance from it.

Seeing you two on the placement, I'll tell you what the operation is.

'It's easy for the two of you to do. If I go inside and defeat the Demon Clan, there's a chance that the Fast-Running Demon Clan will escape.... it's the job of the two of us to stop the demons from moving then and beat them back inside the room'

'Well, then I guess I should use this arrow!

So Alma takes out the arrow she was carrying.

This arrow is a Magic Inhibitor arrow for the Demon Clan previously made by Lurii.

With this, we can stop the demons from moving.

'The eagle, that's enough!

That's what Iris said, putting up his usual spear.

Well, with the power of Illis, it would be easy enough to knock the Demons back into their hidden rooms without weapons or anything.

The important thing is that it starts here.

"Lurii is here, and the moment I open the entrance door, keep your consciousness focused on the magical reaction in the wall."

That's what I'm talking about. I'm pointing to a wall just outside the entrance.

This is the most important part.

'In the wall, you mean the hidden room?

'No, it's either the wall itself. This wall is equipped with magic props, but only during the operation of the concealed room walls can you interfere with them. In the meantime, I want you to break one of the magic props inside'

"Break... What kind of magic equipment do you have?

"This is the magical prop of a magical reaction."

With that said, I impart magic to the magic stone at hand.

Of course, the magic props actually planted inside the walls are very complicated and not like I can make on this occasion.

It's just, like, a magic reaction.

But this would suffice as a sample for Lurii to find the target demon prop.

'Okay!... I don't see a magic reaction like that right now, but you're going to see it when it opens and closes, right?

'Oh. It's only for a moment that I see you, so take a good look.'

'Yes!'

With that said, Lurii began to focus his consciousness on the wall.

It will be a bump production, but Lurii's technical skills today will not fail.

With that in mind, I turn to the door of the entrance to the hidden room.

"Everybody ready?

'You can do it!

"It's all right at all times!

"It's ready!
