I finished my story and went outside.
　The zunana grass is labeled in kilograms, probably because it was cut into small pieces or because it was not picked one by one.
　It was 100kg. 　If each plant weighs 10 grams, that's 10,000 plants.
　I guess we can't consume all of it, so we should sell as much as we can and think about the rest later.
　Do you want to try to extract only the active ingredients?　I don't see much value in using .......
　Even if a small amount of the drug has the same amount of active ingredient as a large amount of the drug, it will just be trapped by the upper limit.

　I'm sure you'll be able to figure out how to use it.
　I feel like it's a waste of time to spend two years just doing routine work after having come all the way to another world.
　Let's see if we can't shorten the time.

　Let's start by analyzing the reasons why logging takes so long.

　First, there is the problem of demon disposal.
　If you cut down a tree, but the demon escapes before you can cut it down, you will have an influx of demons that have been driven out of their homes into the town.
　Because there is a limit to the amount of time that can be spent dealing with this problem, it is only possible to cut down trees for about five hours a day.

　The second problem is simple logging speed.
　After solving the problem of the demons, we can only cut about 1/20th of a square kilometer in five hours, so it will take six months to retake Brokens if we cut 20 hours a day.
　This could be doubled by increasing the speed of flight.
　You may have to sacrifice the Zunana grass, though.

　That's about it.
　To achieve this, we need to get rid of a lot of trees.
　I don't know if there's anything you can use to accomplish that.
　...... Oh, by the way, you have surplus magic.
　I've only been cutting trees for five hours or so, and I haven't used half of my magic while cutting.
　It would be better to store up magic power all day and throw it into the forest at once.
　You can then boost it by logging for five hours. This will be more efficient than doing it purely with magic power.

　For more information, see ......
　Burning or blowing up the tree is a good option.
　If it burns, it burns, so why not blow it up?
　There was some kind of warding magic, so it would be strong if we used that as well.

　But it's not a good idea to go that far on your own, should we consult with them?
　I'll just prepare the magic power.
　Imagine an explosion, not a fire magic, but a pure explosion of magic tools.
　And a warding spell to confine the explosive power.
　Both of these things can be done with magic, since we have magic tools.
　It's relatively easy to imagine.
　The fact that you are sure of their existence is a big deal.

　I don't know how long I can store the magic power that can be activated, but for now, I'll divide it about three to one between the explosion and the ward. Of course, the warding will break down, but there is no need for the warding to endure.
　It is enough that even a part of the blast is reflected and destroys the low positions on the ground.
　I'm thinking of setting up the wards about 30cm above the ground, so that only the lower surface faces the ground, and firing a lot of magic explosions just above the ground.
　I went to bed praying that I would have enough magic power to use it until tomorrow, if possible.

　The next morning, my prayers were answered, and the magic power had accumulated.
　There was no way to check, but I had a feeling.
　At any rate, I decided to go to the guild to ask for permission.

　I arrived at the guild. 　The mayor was awake.

"I'd like to destroy a tree with a big spell, is that okay?

"Big magic, how big?　I've never heard of a spell that could take down a tree.

Is it that hard?　Can it be burned?

　I wondered if there was any reason why it hadn't been burned, but I had to ask.
　If it can be burned, it's the easiest way.

No, it's not possible. Three days after it's been cut, it will become scaly and flammable, but a tree left standing in the demon's territory is not something that will burn.

　It's not a matter of wildfire or anything, it simply won't burn. .

I don't know how powerful the magic would be to shatter the tree, so I'd like to try some things at the beginning of today's felling time, is that okay?

"Sure, I'll pay you if you can fell the tree. 　If it doesn't, you can just go ahead and cut it down, or you can give up and go home. 　I can't ask for anything more than a cheap tree to cut down.

　Okay, let's give it our best shot.

　Just before noon, I came to the guild as yesterday.
　The same orders as yesterday were given to the mayor and we started to act.

　Unlike yesterday, I flew through the air and went a little deeper into the forest.
　There's a good chance that there will be more collateral damage than yesterday.
　It's been about 15 hours since I started storing magic. 　My available magic power is 530,000.
　More precisely, it's about 540,000, but that's trivial.

　At any rate, I went into the forest for about two kilometers to check.
　Prepare a 10m x 10m area with about 12 magic wards and about 48 magic explosions.
　The explosion spell seems to be a bulletproof spell, but from what I've heard, I think the spell of the ward activator can pass through the wards.
　If that's the case, the wizard shouldn't be able to use the wards on the mages, unless there's some other way.

　Well, test fire for now. 　It's only enough magic for one strong wizard at best, but I have high INT and a warded blast spell to trap the explosion.
　Activate a ward 30cm above the ground, fire four projectile explosion spells using 12 magic power per shot, and retreat.

　The whitish ball explosion spell bypasses the ward as expected and lands on the ground.
　The inside of the ward turns black, and a moment later, the ward breaks and an explosion occurs.
　Then, a few moments later, a tree falls. 　It seems to have worked.


　After that, the black wolf that I had checked on the tentacles before the experiment but hadn't dared to look at came falling down.
　Its legs exploded, and then it was blown off the ground as the wards were broken and it fell.
　It was powerful, and it took less magic than expected.
　Unlike the explosions I've seen before, it wasn't red, so the explosion magic might not be the expansion of air due to heat, but simply the phenomenon of an explosion.

　In any case, I was able to confirm that this magic works.
　All we have to do now is to increase the scale of the explosion and shatter it.
　If the demon breaks the wards before the explosion, it's no use, so we'll have to change the procedure a bit.
　First, put away the blade wand and intentionally slow down the magic.

　Then, ascend into the sky and fire about 10,000 shots at once at the ground.
　Evenly distribute them over a square about a kilometer on each side.
　Even though it's a bullet, it doesn't have a shape as an object, so it doesn't take shape even if it stores magic power, and it becomes a bullet only when it shoots.
　Thanks to this, it can fly without interference.
　Perhaps I should have used it to shoot birds.

　After overtaking a flock of bullets flying to the ground, deploy a ward about 5 cm above the highest point on the flat ground, and leave upward.

　Immediately after impact, there is a deafening roar.
　The ground of the forest turns black, and for a moment it seems to rise, and then the trees and monsters are launched.
　Then the trees fell and the monsters fell.
　The forest, which used to be green all over, is now black with torn grass and fallen trees.
　Together with the corpses of the demons, it is a picture of hell.
　It's a wonderfully destructive force.
　I thought I heard the sound of an increase in level mixed in with the explosion, so there's a possibility that it will be even stronger tomorrow.
　Of course, there was no Zunana grass left even with the current power, but there was no choice.
　It's a bit of a surplus anyway.

　Due to the difference in elevation, there were about ten trees left, but we cut down the trees in those areas and completed the cutting of one kilometer square.
　I checked my guild card and found that I had cut down an astonishing 42,562 trees.
　If the reward per tree is reduced by a factor of ten, why not just cut down 20 times as many trees?
　It's not logging, it's blasting and dismantling, but since the guild card allows it, I guess it's okay.
　I quickly collected the demons - many of which had their legs torn off and their bellies damaged, but there seemed to be some usable meat - and the hard wood, and headed back towards town.

　On the other hand, I started to cut down the trees while mowing the lawn.
　It's not as efficient, but it's also a good way to collect Zunana grass and save magic power.
　Since I won't be using the full amount of magic, I'll use the surplus to blow up the forest tomorrow.

　After about four hours, you hear an explosion that is much quieter than the forest explosion.
　You finish logging, hunt some demons, and return to the guild.

The explosion was a success.

　You hand over your guild card to a staff member who was waiting with the mayor.

I heard a tremendous explosion coming from deep in the forest.　......445,000 bottles?

"Yes, about a kilometer square, magically boom.

That's great ...... great, but ...... how much magic did you use?

Roughly ...... ten thousand wizards, I'd say.

　That's about 54 wizards each, which is a little strong.

"...... Okay, so we know that no matter how hard we try, we can't imitate them. 　Can you do the same thing tomorrow?

Yes, that's the plan.

　Please don't make it sound like I'm not human.
　From my point of view when I was on Earth, 20 hours of running to Photoren is more than enough to be human.

I knew it was out of the ordinary, but this much? 　I think we'll be done with Brokens in 30 days.

Maybe three, 40 days. 　What do you do with the trees after they're cut down?

We'll burn the trees as soon as they're burnable, and then we'll take control of the area we've cut. 　Once we have control of the Brokens, we'll rebuild the outpost.

　Rebuild it.
　Well, there won't be any exterior walls left.
　I don't know how we're going to do it with the demons attacking us, but I'm sure we can manage.
　We could push the front line up to the front and then build behind it.
　However, the narrowest point between us and the demon's territory is Brokens, and it gets thicker from there, so it might be hard to control.
　Oh well.
　Construction is not my area of expertise, I'm sure the experts will take care of it when the time comes.
　You don't have to do everything by yourself.
　For now, just focus on destroying the forest with your magic and status.

I understand. 　In short, all I have to do is cut down the trees and blow them up.

That's it. 　You got it.

　We'll figure out the rest when we get there.
