The time goes back from the wedding of Selene to the time of returning to the wilderness.

"I was able to master [Transfer Magic], but I'm still lacking in training."

Although long-distance transitions are difficult, I am used to medium- and short-distance transitions in the visible range.

Until now, the [Void Wilderness], which used to fly with a flying broom, has been used together to spend several days checking the magic devices placed in various places.

"I thought about living with Selene, and built a base in the outer edge of the [empty wilderness], but you still need a base in the center."

In the center of [Void Wilderness], there is a magic tool that seals the great devil, breaks it down into magic power, and annihilates it.

In the unlikely event that the seal of the Great Devil is broken or the magic device breaks down, we want to keep the base nearby so that we can quickly repair it.

"Now, it's on. Oita trees are growing here too."

It used to be a small place in the past, though it used to be a place with nothing to do.

The various trees that were planted formed a forest, and in the center of it, one head was able to jump up and look up at a large tree-the world tree.

"Yeah. The world tree is growing fast. And the surrounding area is very magical."

Even today, microorganisms and insects are breeding in places of high magical concentration where trees were planted, and slime and small animal monsters barely live on the outer edge of the wilderness where weeds grow even under low magical power.

Within a few decades, the forests created at various places in the [Void Wilderness] will be connected to each other, forming a huge forest, and the concentration of magic inside the Great Barrier will be small enough for small animals to survive. Would.

By that time, I think that the setting should be lowered by one step so that small animals can flow into the Great Barrier that created the whole [Void Wilderness] area, and I hope that the Great Barrier will disappear in the future.

"Oh, there's a small fountain."

When I walked to see the trees in the forest, there was a small fountain springing up near the world trees.

Perhaps because the roots of the world tree had dug deep into the ground, the water had gushing out due to the water pressure inside the ground.

The sight of such spring water can be seen at various places in the [Void Wilderness], and the seeds of the plants carried by the wind are germinating and green spaces are being created.

"Yes, think about the flow of a small river at the spring ... I think it's good to build a house around here. Before that-Summon Servant!"

Before the base is set up, use the transfer magic to apply a summoning spell that calls your own kin, causal, or contracted object.

Tet, his buddy, came out of the shining magic circle with light steps.

"I was called by a witch! And I missed it!"

Tet emerges from the summoning magic circle, poses with Shakin, and immediately catches her with a smile with a smile.

"Tet, thank you for going with the experiment."

"Huh, welcome."

When the distance from the royal capital of the Ischair Kingdom to the [Void Wilderness] was transferred with Tet, it consumed about 300,000 magical power.

However, with transfer magic, the magical power consumed increases at an accelerating rate, depending on the distance to be transferred and the number of people and mass.

For that reason, if it is an efficient long-distance travel method, it is more efficient to call a Tet with a [summoning magic] after moving alone, or a fixed type of moving magic tool like [Transition Gate] It is good.

"Now, let's build a new house here. Tet, please improve the ground."

"Yes, that's it!"

When Tet holds his hand over the ground, the ground in a predetermined area wriggles and the trees begin to move.

In order not to cut down the trees that were planted and planted for the establishment of the base, I had to move a little with Tet's earth magic.

Then, on the vacant land, Tet makes a foundation with the bedrock of compressed earth and stone, and then I use the magic of [fixation] so that the foundation does not deteriorate.

"Now, a temporary house-<< Creation >>!"

A temporary house is built on the base thus created with creative magic, and a transfer gate is set up from a magic bag to connect with the house near the southeastern outer edge of the [empty wilderness] currently used.

"In the future, I'd like to connect transfer gates like hubs from the center here to various places."

"What is a hub?"

"Well, in a nutshell, it's like a wheel."

Draw the wheels and axles so they are easy to understand on the ground, and Tet will understand right away.

"Is it a hub! Tet is one more clever!"

"Hmmm, yeah. And we had the architects of the royal capital create blueprints for the base, and little by little ..."

When I was talking about trying to build up my magic little by little, I felt strange movements within my sense of magic.

"Witch? What happened?"

"Something is sucking the magic of [Void Wilderness]?"

Until now, this [emptiness of the void] has been under extremely low magical power.

Trees have been planted in the last ten years or so to release my magic and increase the magic concentration, but the magic is still not enough.

If an entity that absorbs magical powers appears in such a situation, there may be a delay in the regeneration of [Void Wilderness].

"Tet, let's go see him."

"Yes!"

I take out the [flying carpet] from the magic bag and search with Tet for a place where magic is absorbed from the sky.

While concentrating magic on his eyes and watching the flow of magic, he was sucking up magic so that he could breathe through gaps in a slight crack on a flat ground without any change.

He slowly lowered the [flying carpet] onto the ground and asked Tet, who is good at soil magic, to look under this ground.

"Witch. A building is buried under this ground."

"Ah, the ruins of an ancient magical civilization.

Born in the aftermath of the magical runaway [empty wilderness], the buildings at that time were left underground.

Previously, when searching the central area of [Void Wilderness], I found a control magic tool, created a magic tool with the same function using [Creative Magic], and incorporated it into the barrier management system.

Also, although I thought that [the wilderness of the void] may have preserved the heritage of ancient magical civilization, I had no opportunity to investigate it.

No way, I didn't think there were any more archeological sites in operation.

"Let's isolate and excavate at the barrier to avoid any impact."

"Yes, that's it!"

Install a barrier magic shield to block the absorption of magical power, and repel the soil in the barrier with Tet.

"It doesn't seem to have any effect on the creature's magic or activating magic."

Even if it says that it absorbs magical power, it seems that animals and plants absorb the excess magical power emitted in the air, and it does not seem to absorb magical power directly from living things or inhibit magical activation by absorbing magical power.

"Maybe a facility that operates automatically by absorbing the magic of the air has begun."

If that is the case, the reason why they started to work because the magical power began to be supplied to the [Void Wilderness].

"Witch, there was something."

"Is this ... concrete architecture?"

Despite the magical protection and immobilization, it was apparently able to excavate part of the building.

If you carefully dig up and throw away the surrounding debris so that it does not break with Tet, a building about the size of a gymnasium will appear.

"Witch, what is this?"

"I don't know, but it is. Let's go in and check it out."

I try to find and open a place that looks like a door.

However, the doors remain tightly closed, perhaps because most of the functions have been broken because they were buried underground for 2000 years.

"Is there any help?-" Laser ""

I create a light blade that converges light on the tip of the cane, and burn off the door.

"Oh, the witch. Is it okay to work in power? The archeological site is precious."

"Isn't it good? Even if you handle it a bit sloppy. At worst, if there is any material of runaway of the magic experiment, you have to destroy it."

If the material of the magic experiment that caused the [Void Wilderness] remains, it must be destroyed to prevent the disaster from happening again.

Then inside the building was dark.

"It's dark.-" Light ".

The underground facility buried for 2000 years has traces of human inhabitants.

It looks like an underground shelter.

Weathered people's clothes and mummified corpses roll around.

Some people are fighting with each other, and some corpses with their heads collapsed.
