Going Back and Forth Between Earth and The Other World with Space Time Magic

After handing the caught Devils over to Lella and sending Aya and the others home, I went to the [Tower of Sunrise] by myself.

Its because Id like to strengthen the [Brown Belt Sword] to prepare for the upcoming fight with the Devil race.

Of the Brown Belt Swords Trial, the only one remaining was [Light-attributed monster subjugation 0/30], so I completed it in around 2 hours and my level also rose by 1.

The next morning, I stopped by Masamune-sans place first thing in the morning before going to work and left the [Brown Belt Sword] to him.

Since it became White Belt Sword Brown Belt Sword, its would be that color for sure.

Im looking forward to its completion.

And then, on the evening of that day,

The escaping Devil leader, who still had a [Tracking Beacon] attached on him, became unsteady on his feet as he walked in the forest alone with no subordinates and food,

but after struggling, he arrived at a cave in the side of a mountain and went inside.

When he passed through that cave, the view suddenly broadened and a really huge, dome-shaped space spread out.

Somehow or other, it seems the inside of the mountain is hollowed out.

Theres a huge hole leading outside at the topmost part of the dome-shaped hollow and light comes in from there.

And then, the entire hollow was a huge town.

Its the [Devil races town]!

It was in such a place, huh..

I sent a [Tracking Beacon] to fly around the place, checking out the situation of the town.

There are many devils residing inside the town, probably around 10, 000.

After that, the ones that caught my eye are the detention-facility-like facilities located at several places throughout the town.

When I tried to check those facilities out, they housed a large number of human slaves and were made to do forced labor.

So theyve been abducting humans and turning them to slaves to make them work, huh

The people, who were turned to slaves, are being lashed by a devil with a whip.

All of them had become thin and had ragged figures.

Whats to be done with this

After work, I called Mai-san over and teleported towards Lellas place with everyone to discuss what were going to do from here on out.

Seiji, did you finally find it?

Yeah, Ive found the Devil races town.

I showed everyone the video of the Devil races town.

Its quite a big town, huh. There are many Devils, too.

Ah! Seiji-sama, people are forced to work.

After seeing people being lashed by Devils with a whip and forced to work, Elena had a sad-like expression on her face.

Onii-chan, are we not going to help them right now?

Aya looked a little angry.

Aya, I understand what you feel, but if we attack recklessly, it would be troublesome if the people, who were turned into slaves, are held hostage. Lets come up with a plan properly.

U-, Un.

After that, we talked about it thoroughly with Lella and decided to start the attack with the elite few on Saturday.

I can gather soldiers if its around 3, 000 people, but do you really not want it?

Yeah, the Devil races town is far, its better to reduce the number of people to a certain extent in order to teleport them with my [Teleportation], besidesits a hindrance.

I-, Is that so

Well, Ill leave the selection of personnel, who will participate in the Devil raid on Saturday, to Lella.

Onii-chan, what kind of preparation should we make?

Ah, thats right~, prepare by raising your levels or something?

Ill go, too!

It was Mai-san, who first showed great interest on leveling up.

Certainly, since Mai-san wasnt acting together with us, there was a little gap between our levels.

Im a little uneasy to let the girls grind levels alone, but its fine if I rush over quickly in case something happens, right?

That week, for three daysWed, Thu and Frithe schedule was repeated with me sending the 4 peopleAya, Elena, Hilda, and Mai-santo the [Tower of Sunrise] in the morning before going to work, the four of them raising their level on their own during noon and me fetching them up in the afternoon.

On Friday night, at the time when they finished grinding levels, their levels rose considerable like this:

Elena, level 50.

Aya, level 41.

Hilda, level 47.

Mai-san, level 38.

And then, Ayas [Wind Magic], Elenas [Staff Technique] and Mai-sans [Body Reinforcement Magic] rose to level 5 respectively.

Since theyve become strong to this point, theres nothing to be afraid of anymore with the fight against the Devils.

We prepared for defeating the Devils tomorrow and fell sound asleep.
