After getting permission from the students, search through the magic bag to find what you need.

First, it’s important to drill a hole in that log barrier.

It doesn’t have to be big.

Small enough to throw a potion at…

“Ah, here it is.”

Wood corrosion solution.

Made based on the body fluids of mountain slime, which mainly ingests and decomposes plants and trees.

This is something that corrodes plants and wood.

Originally, it was used in the event of a landslide or when woodcutters cut down huge trees that were difficult to cut down, so adventurers rarely use it.

It’s a good thing I made it just in case I needed it.

I’m lucky that I have mountain slime’s body fluids.

“Miss Schnero. Could you please check where there are no goblins beyond the wall?”

“Uh, this way.”

If you happen to make a hole in the log barrier, go to the side where there are no goblins as much as possible to avoid being caught right away.

I felt students snooping around behind me, as if they were curious about what I was going to do.

Certainly, wood humus may be a bit unfamiliar to adventurers.

Unless you’re dealing with plant-type monsters like Ents, there’s almost no use for it.

Sigh─

Carefully open the cap of the potion and gently spray it onto the log barrier.

OK.

Push…

As if a metal was dipped into an acidic liquid, the wood began to bubble and slowly melt.

“Wow…”

“What is that?”

The students were amazed to see that.

“Is it wood corrosion liquid? It’s been a long time since I’ve written anything.”

Even Mr. Larsen looked at me curiously.

I’ve seen it before, and I think I’ve probably even used it myself.

Because it’s not common.

“Yes. It mainly corrodes trees and plants. As you can see the effect. Please note that it is also effective against plant-type monsters such as Ents and Carnival Rose.”

“I see.”

“Amazing…”

“……”

The students seemed like active adventurers, but it seemed like there were still things they didn’t know.

I feel proud that I have broadened the knowledge of my friends who will become great adventurers.

Push profit─

So, he drills a hole in the log while constantly checking to see if he gets caught by the Schnero student using detection magic.

A small hole barely big enough to fit two people’s heads was opened, and the inside of the fortress was finally visible.

“Are you going to widen the hole from now on?”

A Cumel student asked that question.

Well, I’m definitely planning to open this area widely and infiltrate it.

Not yet.

Then wouldn’t we end up fighting 300 goblins head on?

“Let’s use this first.”

He rummages through his magic bag, finds a mask, and hands it to them.

“This is…?”

“Is it a mask…?”

It’s a bit big to be called a mask.

It’s so big that it covers the entire face.

Additionally, the material is made of rubber, so it sticks to the face and blocks outside air from entering.

The eyes have transparent plates that allow you to see the outside world.

And there is a thick filter near the mouth that filters the air.

“Well… it’s not just a mask, it’s a gas mask… that blocks poison.”

“Gas mask?”

“Ah. It’s something you use when exploring a poisonous area.”

“Yes. It has a purification filter so it filters out poisons from the air.”

It felt like I was seeing Mr. Larsen for the first time too.

Well, basically, people with strong magical power can create a magical shield in their bodies that blocks poison.

There is no particular need for it when going to highly poisonous areas or polluted places.

However, this gas mask is necessary for people like me who have weak magic power, or for situations where magic power cannot be used.

I made the purification filter myself using clean mush, so I can guarantee its performance.

Well… these students have high magical power, so it may not be necessary.

This is because they will not yet be used to fighting in highly poisonous areas or in situations where the air is polluted.

I thought it would be a good idea to wear this so I could focus on the battle.

“…Are you really spraying poison?”

Students who were handed gas masks were surprised and asked questions.

Well… as you say, it’s okay to spray real poison.

There is also an explosion potion containing extreme poison that can completely paralyze a goblin with just one breath.

If the range is expanded by increasing the capacity as much as possible, it is not impossible to cover the entire fortress.

But I’m reluctant to use something like that in a forest like this.

Although it is deep in the forest, if the poison spreads with the wind, it could cause damage to surrounding villages.

This is because it can have a serious impact on other monsters, animals and plants nearby.

I don’t know if the situation is so desperate that there really is no good solution, but it’s not that serious right now.

Moreover, in the first place, this request should be made primarily by students.

You can’t use such extreme measures to deal with it.

“It is not a severe poison. Does it just make your eyes sore and make it difficult to breathe? The effect quickly subsides in about an hour or two.”

A chemical substance made by mixing tarcos grass leaves, which cause severe stinging when they come into contact with mucous membranes such as the eyes or nose, and rumyl root, which promotes the secretion of fluids in the body.

It is said that the eyes are so sore that tears pour out without stopping, so it is called tear gas.

As I told my students, the effect lasts for about an hour or two.

The only reaction would be itching in the eyes and tears and snot pouring out?

Even if you prepare a little, it is not very effective.

However, if you happen to be unprepared, it can be extremely embarrassing.

“…Is there something like that?”

“Alchemy is amazing… There are all kinds of star potions. It corrodes trees… and stings your eyes…”

It’s definitely interesting.

If I hadn’t read it in a book, I wouldn’t have known about the existence of these things at all.

Actually, when I first saw it, I thought it would be better to make mainstream potions like healing potions and fire potions instead of making things like this.

But learn about adventurers and the numerous terrains and monsters that exist in the world.

There are countless situations that we face.

The more I learned about such things, the more I thought I would need various potions and consumables to cope with so many variables.

Although it is said that most problems can be solved with magic and magic, there may eventually arise situations where magic cannot be used.

Because there may be people like me who are not good at using magical power.

That’s why we made things like tear gas, gas masks, and wood etching liquid.

In fact, like now, there are students who have temporarily received A-rank adventurer registration certificates.

Isn’t this how it works?

” Looking at it, it’s definitely a mess. If the effect lasts for about an hour or two, it will probably be almost resolved, right?”

When I said that to the students with a grin, they nodded.

“I will sort it out soon.”

Looking through the hole, it appears that someone was seriously injured, as expected.

The goblins’ movements are quite chaotic.

If tear gas explodes in this situation, there will be chaos.

“It’s fascinating. First time using a gas mask.”

“……”

I make sure the students are wearing masks, and I wear them too.

Teacher Larsen doesn’t seem to be using it since he will protect his respiratory system and eyes with his magic power anyway.

If you checked…

“Throw it.”

Prepare a potion bottle containing tear gas solution and a flame potion that will vaporize and spread immediately when exploded at once.

This amount would roughly cover the entire fortress area.

It would be a pity if there were people or animals passing nearby… but anyway, if you leave right away, you will recover quickly.

Swish─

Throw the potion bottle into the hole in the log barrier.

Fly as far as you can, and hit hard enough to explode in the center of the fortress.

“Kkgeong?”

“Kyaak?”

The goblins suddenly saw the potion bottle flying and tilted their heads.

But it’s too late to notice now.

Clang-Clang.

The flame potion breaks and ignites due to friction.

The fire spreads quickly, and the tear gas liquid inside the other potion bottle begins to boil.

It changes from liquid to gas and cannot withstand the increased volume.

Pow!

The tear gas potion exploded and the gas began to spread at an incredible speed.

“Keez?!”

“Kyaaagh?!”

They are startled by the sound of the explosion.

But the startling starts now.

Now, they are panicking and taking advantage of the time when all eyes are focused in that direction…

Sigh! Sigh!

Spray wood humus over the log barrier.

Now the hole needs to be widened to allow them to pass through.

Push profit─!

If you spray a large amount at once, it corrodes quickly.

Although mountain slime body fluid is difficult to obtain and expensive, its performance is certain.

“Keueeek?!”

“Kyaaagh! Kyahak!”

As if it was slowly starting to take effect, the goblins near the gas began to cause an uproar.

Bodily fluids are gushing out from the goblins’ bulging eyes and noses, and the goblins can’t stand it and are rubbing their eyes and noses.

Not a good choice.

If you rub like that, the particles will further damage the mucous membrane, which will only cause you to suffer more pain.

“Keek?!”

“Keeek!”

In panic, goblins rush out to check the situation.

Those guys will soon become victims of tear gas anyway.

Okay, I drilled a hole.

Slowly, the gas began to spread throughout the fortress.

“Okay, you can go now. Students.”

Saying that, let’s look back.

“……”

“Ah, yes.”

For some reason, the students who had been standing there in a daze were startled and started to go into the log hole.

…what?

Was the gas mask ineffective?

Well, it looks like it’s running fine.

…Oh, perhaps.

Was it too much…?
