My job is to investigate other worlds!　~ A dull ex-salesman, but easily liked by girls of different

Assigned room, bug checked.

We managed to get an extra spot for all three of us to take the test. But it's too dangerous here. Let's go register for the test in the capital city as soon as possible.

'Huh?　Was it really so hard to see them?　I'm sorry Ryota, maybe I didn't learn enough.

"How can you pass the exterminator's test in the Alps?　Thank you, sir.

'No, it was just an unexpected turn of events that I had trouble dealing with. That's not the Japanese way of doing things.'

"Ryota-sama, this is a place near the center of the Alp continent. We would like to set up a relay point with a communication satellite, if that's okay with you?

The location is a bit off-center, but the elevation is quite high. If you go to the mountains, it goes up even higher. South Ares will have better coverage and easier access to our host families' territory.

It's true that there are some areas where it's difficult to communicate with satellites. "That's true, there are some areas where it's difficult to communicate with satellites," he said, "but if we send a communication terminal to the Viscount as an artifact, it could be used to contact Viscount Sailor in an emergency. But do you have access to power or a suitable location for it?

There is a valley in our possession that is almost inaccessible. I propose the installation of a satellite transponder there with a wind turbine.

'We can't make solar cells, and power generation is only during the day. You can make a generator motor, but you can't make a hydroelectric generator because it's easy to get caught along a river. That's why you're in a valley where no one comes to visit... but wind turbines are unstable and inefficient.　I don't suppose you could afford the rechargeable batteries?

A waterwheel can generate electricity as long as the water doesn't run dry... but the wind isn't conducive to a steady supply of power, and there's no room for a rechargeable battery.

The topography of the valley is such that there is almost no wind. We will design it so that there is plenty of room to generate more power. The energy reserves are not necessarily power, the surplus is pumped up from the water to be used as potential energy. It is inefficient, but its purpose is communication.

Well, as long as the window flowers are okay, we're good. Are the parts complete?　

Up a secluded and inconspicuous valley

'There's a shallow river down there, but we can't get a water wheel. The wind is steady, so you're right.

The path of the wind that connects the mountains to the territory. The wind direction seems to change between day and night, but modern windmills can handle it. The valley of the wind is not too strong and not too weak. It's the best place to be.

Yes, we are going to build a communication system and more water tanks on top of this valley. The wind turbines will be placed on the sides of the valley and the excess energy will be used to pump up the water at the bottom. When there is no wind or when the output is increased, the water will be pumped up to generate electricity.

Primitive and energy-lossy but sufficient for communication, no batteries needed, designed to last 3 years without maintenance. As expected, no problem was found.

Start construction

The depression is dug out and the stones are laid down. Next, the plaster is applied on top of the stone. When it dries to a certain extent, the last part is covered and the last part is covered with a coat of plaster as well. There is a water intake at the top and a drainage pipe at the bottom. The inlet is covered with a fine round net to keep out dust.

I release the stopper on a timer to get it running when it's hardened. When there is wind, the water is pumped up. When there is no wind, the drainage pipes open automatically and the water returning to the valley turns the generator motor. It seems to work for more than 5 years without any maintenance, although it also receives a little bit of dust.

'We also need to install a wind turbine and a pumping machine. It would be easy to rappel down, wouldn't it?

When I came to another world, I had to do my first jumping job. Window flowers are too highly regarded by me. I've never done it in Japan either, so I'm not at all sure... I mean, I'm scared?

Installation completed

"The wind was shaking and the stones were falling down, and the windmill was gunning for my head... I thought I was going to die...

Please prepare the cliff above the windmill and plaster it with plaster, too.

'....Yes....

.........The relay point was set up, we just needed to get it set up and running after it had dried, and then we headed to the test site in Lutzen, the capital of the Alps. Anyway, working at heights was scary!

Lutzen, the capital of the Alpes Guards

When we arrived at the capital, the retainer, Dominic, came to meet us. We secured the informal consent of three of the five examiners........

The hall was crowded with people who wanted to become exterminators and guards, and the races were diverse. Furthermore, the reason why there are two types of mercenaries, the guard and the exterminator, is that the guard is specialized in guarding demons and bandits, while the exterminator specializes in defending and protecting the contracted cities. The Exterminators are specialized in dealing with demons and bandits, while the guards are responsible for the defense and security of the contracted cities. If attacked, not only the demons but also the humans are targeted if they are enemy soldiers.

Guardsmen are paid a fixed rate of pay for defense, with basic waiting lists and defensive facilities such as city walls. Exterminators can choose the time of attack and the number of men to hunt and attack demons, but they are paid a fixed fee.

The rules are different in the case of cities.

Guardsmen are forced to participate in the defense of a city. Guards must be prepared to kill even if they are forced to do so by the peasants or warriors. Exterminators are free to join in. But in the case of a demon attack, if the exterminator does not participate, his reputation will be tarnished. But in the case of a human invasion, they can say no.

Furthermore, the reason it's limited to defense is to avoid a battle between the Alp mercenaries.

''You arrived early. You're very competent, and we've got three judges under control. Don't worry.

Unless the result is very bad, I passed first. Well, you don't usually think of cheating because qualifications above your ability will ruin you. That's how serious this job is. All we asked for this time was to qualify Anya for the exam and to get her license, but....

Ryota, let's aim for the release of the limitation!　We're exempt from censorship in town and country.

That's a good one!　I don't want to see new inventions anywhere in the world, you know.

Even though I have the informal consent of three people, two of them started saying irresponsible things. If you meet the qualification requirements, you'll pass, but at least you'll be fighting a large special demon, right?　I think I just need the necessary qualifications.

''That's a useful qualification. But if you're above the big special, it's more difficult to find your prey.......Ryota-sama. There's a forest to the east outside the border, and I heard there are many big game.

Geez, even the window flower is going to be interested in it... and I'm pretty sure it's unlocked, which is better than a Kong Troll or a giant crocodile tortoise, right?　I'd avoid it if I could.

But entering the country without censorship is very convenient for investigations... hmmm.

Furthermore, only this time, Window Flower said that we are free to use weapons other than the main gun system. Midia and Manya also [Carl Gustav and Simonov will be fine! And then they start to fuss. In the end, we were pushed out of the border and ended up going to the East Forest.

The Eastern Forest

The target is a lone 7m class king troll.

Is the test based on size?　A fishing tournament?　And 7 meters is about the size of a small telegraph pole.　It was too scary to fight such a giant.

So I made Window Flower promise to limit the battle to long distance. However, when they come before the forest, they will run into an incredibly powerful enemy....

We have a visual on an incoming object. But it is very big, isn't it?　I'll have to identify... this!　The Superior Dragon!　All green, all armed, including the main gun!　Change ammunition type to adjusted fragmentation rounds, armament support system activated!

No.....

What do you mean, a superior dragon?

I thought the research mission was supposed to be less dangerous.

Will I ever win?　No. Do you have an eye for survival before that?　I broke out in a cold sweat with such anxiety and hurriedly prepared to intercept them.
