I’m an Adventurer! ~Musou Skill is Plane Magic~

When I laid blankets in the carriage I brought in and laid them down, my complexion returned to normal and I stopped sweating. Apparently, it seems like there is nothing else in life, so it's a relief. As a precaution, please remain at rest for a while.

In the meantime, they tea with Kikka's water magic and Luca's fire magic. Sit in the car seat near the carriage and calm your mind with the scent of tea. If you feel comfortable, find out what caused it.

The cause of ill health is definitely that of the pontoon (...). But what the hell is going on?

"I don't think it's bacteria or microbes. It develops too soon, and it seems to recover as soon as it leaves the depression."

"My balance magic didn't detect any foreign matter. It could be caused by magin, but in terms of concentration, it was higher when I was in the dungeon."

"A monster attack or something? Some monsters use spells, charms, magic. Something like a spiritual magic."

"But I didn't feel anything when I perceived the signs. Wu was the only one who could react to something, so I think it was something with a smell...."

"At least I didn't make a sound. It was just a bug squeal."

Hmm, sounds. The charm of Serene was on the song, and insect-based monsters could use their magic on crying. But I didn't feel any strange magic.

Even now, I can still hear a loud bug chirp from the depression. The loudest is the sound of the semi, because it is large or thick and the bass is effective. The next unpleasant sound you hear is probably a butterfly or a butterfly worm. I know you're rubbing your wings together, but it's spreading strange sound waves like a novice violin. It seems like insects and birds are loving females, but I'm not sure I can get along with someone who likes this kind of noise. Well, I'm not a bug or a slut, so it's only natural.

If you're throwing magic on the sound, it's strange that we're still unaffected. The magic line of sound will be thin.

Gus after all? Kristella, are you sure there's anything unusual about the analysis? It doesn't matter if it's trivial. "

That's right. The detailed breakdown is that the magic element is slightly more than this area by two percent, the carbon dioxide that becomes acid deficient when there is more is less than one percent, and the oxygen that becomes acid deficient when there is no more is still slightly more than 32 percent.... "

"Ah! That was it!!"

"Eh!? Which one?

They did it! It's not a mixture of strange things, but the ratio of original things has changed!

"I know the cause of the two illnesses. After all, the gas was also caused by the" oxygen "that we normally inhale. Probably."

"What is oxygen?"

"No, no, no. If we don't have oxygen, we're gonna die. If there's a lot of them, why would they do that? Why is that the cause?

"Oh my, the oxygen comes out from grass and trees, right? Isn't it obvious that there are many in the woods?

Science knowledge up to junior high school level is taught to everyone. In adventurer activities, there are many unexpectedly useful occasions.

It also teaches the relationship between oxygen and carbon dioxide and plants. Among them, he also told me about acid deficiency, but he forgot to tell me about oxygen overload.

No, I may not have been taught in middle school either. Indeed, diving became a topic of cylinders when I talked to my hobby colleagues, and I felt that it was a miscellaneous knowledge taught at that time. It is said that the use of high concentration oxygen cylinders for medical use in diving can cause oxygen poisoning.

"If you don't have enough oxygen, you'll die of acid deficiency, but on the contrary, it's not good for you. I don't really remember the reason, but about 30 percent should have been the upper limit. I think that's what caused it, because it seems to have exceeded that limit this time."

"Oh, is it like drinking too much and falling down?

"That's right. It doesn't have to be a problem if it's the right amount, but if you drink too much, you'll lose your health or, worst of all, you'll die, so it might look like alcohol in that sense."

I see, there's just so much salted plum.

The ratio of oxygen in the world's atmosphere is about 23 percent. It should have been about twenty percent on Earth in the previous life, so there's a little more. I think this is due to the fact that the world has not yet developed and the consumption of oxygen is low, and the large area of forest that has not been developed.

This depression in the middle of the forest is in a sense a space isolated from the surroundings. The wind hardly passes. Oxygen may have accumulated at the bottom of the depression over time so that gas would accumulate in the cave. The molecular weight of oxygen is slightly greater than that of nitrogen, the main component of air.

I should have noticed at the time it was a giant insect. It seems that there was a long time ago when giant insects were walking around on Earth, but the theory that the cause of the giant was due to the high oxygen concentration at that time was powerful. It can be explained if you think that the dragonflies of other worlds were bigger than the advance information because of the influence of oxygen as well as magic elements.

I've also heard stories about using high concentrations of oxygen water to cultivate fish at an early stage. The fish in that swamp wasn't that big, but maybe they were eaten by the goats before they got big. If you look carefully, there may be giant fish that survived predation. Lord of the swamp. Romantic!

"But why did Atai and Daisy just fall down? They're all pinching."

"... unconscious"

I guess you were listening inside. Samantha and Daisy come down from the carriage with the blanket on their shoulders. I feel my voice is a little blurred, but my complexion is no longer the same as usual. Rest assured. Luca makes tea for both of us.

"No, I think it was a matter of time. Sooner or later, I think we all fell down. It just so happens that they fell first."

Probably because of "basic physical abilities" and "proficiency in physical strengthening". Daisy, whose body has not yet grown well, and Samantha, whose strength is not high. It just so happens that the symptoms appeared before, and if the situation was a little different, it might have been me who had the same symptoms as Daisy and I haven't developed any body yet. It was close.

Thank you to Woo-chan for noticing the anomaly as soon as possible. After drinking tea, I erased the empty flat cup and stroked Wu's back lying on my right side. Yeah, it's a nice hairy day, too.

"All right, then, take care and rest today. Tombo, I'll be there tomorrow morning to catch him."

If the cause is known, there are many ways to deal with it. If you know where the poisonous fur is, you can remove it and eat it deliciously.

◇

The next morning after camping for the first time in a long time. After breakfast, the sun is already that high.

I'm floating about a hundred meters above the swamp. Above the outer edge of the pocket. Oxygen is stored at the bottom of the depression, so there is no need to worry about poisoning at this height. If there's anything harmful on the bottom, you don't have to go there. It's a simple story. We're going to manipulate the plane from here to catch the dragonflies.

I don't want to use planar magic remotely because it feels game-oriented and unrealistic, but I can't help it if it's for safety. I don't have to weigh my personal feelings or my safety. Avoid danger when adventuring. That's the adventurer.

By the way, I'm asking everyone else to take herbs. It's a plain job, but the Adventurer Guild's constant request makes it very demanding. It's not bad for earning points in procurement.

I didn't say anything in particular to Woo-chan, but it wasn't unusual for me to follow everyone. Feel like I'm gonna keep an eye on the herd? He's a good kid to look after.

Dragonflies that follow the same route on the marsh are reminiscent of passenger planes that travel between the airports of each city. Though I think dragonflies are lighter and more free to carry extra luggage (passengers). Even if you take a detour, it won't be a problem.

If you think it's easy to get caught flying the same route, surprisingly avoid flat surfaces. It's supposed to be invisible. It's okay to surround it in a large plane and shrink it later, but it's too much work and boring. We also need to play at work. Let's use the nature of the dragonflies to capture them here.

In the middle of the route, stand a pillar on a plane. It is a cylinder about 50 centimeters in diameter and 5 meters in height that matches the size of the dragonfly.

You were alert to the sudden appearance of a cylinder, the dragonfly turns and leaves. When I think about it, I'll be back soon. Then stop at the end of the cylinder. I knew it was a bug. The vigilance against immobile objects is terribly low. The moment it stops, the wings are fixed flat. It's simple. I cut off the neck of the dragonfly that I couldn't fly, and then I cut off the chest with the magic stone. His stomach, wings, and feet were carved into the swamp. Shortly after, the little fish gathered together and disappeared without a trace. You have a good appetite.

Once we catch the other dragonflies in the same way, it's time for the Kamakiri. Other insects didn't have big eyes, and only these two types of glasses could be used as materials.

Most turtles are ambushed, but it seems to be the same even if they become huge. They wait for their prey in the middle of trees and grass. It's not as hard to catch as a dragonfly because it doesn't move. It's over without having to be surrounded by a flat surface. It's too late. I'll just hunt one more and finish it.

Tamara asks me to "make as many materials as I can", but I don't want to hunt too much and destroy the ecosystem. This could be the last habitat for giant dragonflies. He said that the material could be a large crystal, so let John make the bulk.

If we could create the same environment inside of John, we could also cultivate it, but there's no way to supply oxygen. An easy way to electrolyze saline is to treat the chlorine and aqueous sodium hydroxide solution that comes out. They're both plays. Cultivation is on hold.

As soon as I've fulfilled my purpose, I'll retreat to John, have him make two large crystal pillars, and then return to Dorton.

This concludes the forest accommodation and insect collection. But this summer has just begun. Now, what do we do next?
