An investigation of the surrounding area revealed a black swamp deep in the mine.

Miners sometimes told me that there were more undead monsters inside than outside the mine, as expected in the middle of the day.

Soon after the discovery was reported, we headed for the cleansing of the black swamp.

"Light"

When the court magician accompanying him sang the "light" of life magic, a blurry glowing sphere appeared, illuminating the area.

It's a life magic that anyone in this world can use, but when using it, it consumes MP.

Sometimes people don't have much MP, and they usually live with ordinary lamps and lanterns that light the fire.

Light sources in mines used by miners are also dominated by ordinary lanterns.

However, since the lantern is likely to break during the demon crusade, people with room in the MP used "light" as a light source.

This time, too.

As the surroundings became brighter, I heard feathers from behind.

It was bat-shaped monsters that gradually appeared.

I thought I'd be here since I heard it was a mine, but I knew it.

The knights stepped forward as soon as the support magic was cast and everyone was ready.

Everyone is working together to defeat them without danger.

Then, when the battle was over, he stepped back into the mine.

Bat-type monsters aren't the only ones in the mine.

There were also wolf-type and lizard-type monsters.

However, the body is often covered with rocks rather than ordinary individuals.

It seems that there are many monsters with earth attributes in the mine.

As I went further, the number of monsters I encountered gradually increased.

I think it's because the black swamp is near.

Unlike in the woods, the mine was not open, and I felt the density of monsters was high.

However, the battle itself may be a little easier as the direction of attack is also limited.

Moreover, the walls of the mine are full of soil and rock, and unlike the forest, there is little risk of the surroundings burning.

When that happens, it is the division chief who is active.

The division commander was able to perform the fire attribute magic that he was good at one after the other, and then proceeded crisply.

Of course, when I encountered a monster of earth attributes, I used wind attribute magic, which is a weakness.

It seems that the use of wind attribute magic is for efficiency.

After that, they mostly dealt with fire attribute magic.

After a while, the type of monster changed.

An undead monster began to emerge along the way.

The monsters that came out were animal type, but the parts of the body were rotting.

And the smell was as bad as I was worried about.

When I first encountered it, I was unexpectedly vomiting.

So when I encountered an undead monster, I tried not to breathe and fought.

But there are limits to things.

It was difficult to keep fighting while holding my breath, so I eventually covered my mouth with the cloth I had.

It was better than nothing, but the smell was relieved a little.

It may be better to develop something like an odor mask for the next time you crush monsters that emit unpleasant odors.

In the original world, I feel like there was such a mask, but what kind of principle was that?

You don't know anything about it because you don't specialize in boulders.

Then we have to develop it from scratch?

If we just talk about something like this, is there anyone who can develop it?

As I was thinking about the odor mask, I finally arrived at the black swamp.

As I heard in advance, the size of the swamp is not so great.

However, one undead monster after another was gushing out of the swamp.

Somehow, the smell has gotten worse even though the cloth has passed.

I want to finish it quickly and do something about the smell.

"We're gonna stop here. Reapply your magic.Watch out for HP and the rest of the MP. "

"" Yes ""

Well then, let's do some magic.Neighborhood Heels, Neighborhood Protection

"" "Thank you!" "

I feel suddenly, but I don't go in there.

There are a lot of monsters around the swamp, and it will definitely be a series of fights from now on.

Before we started the fight, it was a steady stone to pause and get ready.

At the call of the commander, I stopped in a position where I could not find the monster near the swamp.

Drink potions to restore your HP and MP, or apply backup magic again.

Everyone was ready for the game like before the boss fight.

When I thought it was time to go, the division chief opened his mouth with his hand on his chin.

"Excuse me, may I have a little experiment?"

"Experiment?"

"Yes, I'd like to see if I can purify the black swamp."

Dear division chief, it seems that I have always been concerned about what I talked about during the new cooking meeting at the laboratory.

Although more than a certain concentration of moisture mutates into monsters, it is thought in the royal palace that something with more dense moisture mutates is a black swamp.

From this, the division chief speculated that it would be possible to purify the black swamp as well as the monster in a way other than Virgin's Magic .

The division chief who thought so first said that he wanted to try to purify the black swamp with sacred attribute magic.

"I don't have to go to the cleansing, but I want to see if I can make a difference."

"Did you choose Holy Attribute Magic because it's close to [Virgin's Magic]?"

"That's true, but...."

As division commander, he wanted to develop magic specialized in the purification of black swamps and try it out, but unfortunately he hasn't developed it yet.

So you decided to try it with sacred attribute magic as a next best measure.

"Come here and experiment."

"Yes, this swamp is not that big, and I thought it would be affordable to do experiments."

"But look at the number of monsters.Would it be a good idea to deal with someone other than Lord Dreves? "

At the end of the explanation, the commander called out to the division commander with a difficult face.

The commander and division commander are in the same position, but it is the commander who is leading this team now.

I don't suppose you could have kept your mouth shut after hearing about the experiment.

As the commander-in-chief said, with the division commander out, I think it will be difficult to hold on to the monster until [Virgin's Magic] is activated.

It was tough when I purified the black swamp in other lands.

I'm sure the division commander knows that.

Still, the division chief didn't give up.

"But it's worth a try.If it can be purified with sacred attribute magic, it means that people other than Sei-sama can cope. "

"Well... I hope that someone else will be able to handle it..."

"It doesn't matter if it's the first shot. Please."

"... hahhhh. Okay, okay.However, only the first shot will be tried. "

"Thank you!"

After all, the commander-in-chief was reluctant, but he drank the commander-in-chief's request.

I might have thought it was tactically or strategically effective.

I tried to say that, but it's a mystery whether it's right or not.

After the discussion, the battle began at the command of the division commander.

Well then, let's go. "Holy Arrow"



After listening to the chant, he turned to the division chief unexpectedly.

Damn it, I've never heard of the magic name "Holy Arrow" or seen it in a book.

The magicians around me had the same flickering expression, so it was probably a new magic.

Even though magic has not been developed specifically for purifying the Black Swamp, it seems that a new magic called attack magic of the Holy Attribute has been developed.

You can't develop new magic overnight.

This is Shizuishi, division chief.

"The impact seems to be very small.Let's just say we understand.After that, Sei-sama, please. "

Yes!

The "Holy Arrow" released by the division chief was sucked into the swamp in a straight line.

The state of the swamp seemed unchanged, but it wasn't from the Master Division who was familiar with magic.

However, I didn't have time to listen to the division chief in detail.

Because of the magic, the monsters who noticed us came all at once.

While the knights managed to capture the monster, the magician behind them magically attacked.

As usual, while others were dealing with monsters, I began to develop Virgin's Magic .

I have activated it many times so I feel familiar with it.

But getting used to it is a different matter from getting embarrassed.

As I concentrated, feeling my cheeks burning up slightly, my chest began to feel soft and magical.

Without stopping, the magic is gradually overflowing.

I saw the golden eagle cover all the black marshes and activated the magic.

The surroundings were dyed white instantly.

A little back in sight, I saw golden particles glittering from the ceiling.

You seem to have been cleansed safely.

It's a boulder. Good work.

The black swamp and the surrounding monsters seem to have been wiped out.

There were no monsters in sight, and the ground was spreading out where there was a black swamp, similar to the path I had been through.

While thanking the commander for his hard work, he exhaled relieved.

After that, I just went back, so I took a short break before I started on my way home...

"Eh! Why?"

Undead monsters appeared and shouted.

Immediately after the purification of the black swamp, the nearby area of monsters were often purified, and there were times when I didn't encounter monsters on my way back.

But it's not like I won't run into you at all.

Also, after a while after purification, the monsters will come out again.

Still, it's as springy as it was before the Black Swamp appeared.

Would it be easier to understand how to return to the state it was in before the black swamp appeared?

That's why I thought it would go back this time.

However, I was surprised to hear that an undead monster had appeared that had not appeared before.

Though I dared to annihilate it, the upset did not subside.

"Undead monsters aren't from before, are they?"

"Ah, the monsters of the earth must have been the main ones out here."

I wasn't the only one who had doubts, even though it wasn't enough to be upset. The division commander also confirmed with the commander.

The commander answered the questions without losing his suspicious expression.

I don't suppose this mine has ever seen an undead monster flourish with the appearance of a black swamp, has it?

Just like here, there was a place where new monsters began to gush because of the black swamp.

However, after the purification of the black swamp in any part of the country, new monsters no longer spring up.

Unprecedented anxiety spread among everyone.

"Perhaps there are other causes?"

Anything else?

I've spoken casually, but it's a possible story.

If I could just list the other causes first...

Thinking about it, the division chief started talking.

"If so, could there be other black swamps?"

"That seems to be the most likely...I've searched all these mines, but I haven't heard anything else about the black swamp. "

Really?

It seems that the division commander shared the same idea.

However, it appears that the presence of a second black swamp has not been confirmed in the mine.

Does that mean it's outside the mine?

We all thought about it for a while, but we didn't come to a conclusion.

Even if you decide on your future policy, you should leave the mine first.

In the current situation, the monster may attack me while I'm thinking about it here.

Eventually, the idea was to go back to the settlement and start walking again to the entrance to the mine.

Then, as I walked down the monster I met on the road, I felt uncomfortable with my feet.

Apparently, a pebble got in my shoes.

Though I try to endure it until I get out, every time I walk, it hits the soles of my feet, and I'm worried about the plain.

Hmm, when the next fight is over, shall we hurry and take off our shoes and remove the pebbles?

What's wrong?

"Oh, no, it looks like there's a stone in my shoes."

"Oh, that doesn't bother me.I hope you let me out now. "

As I thought about it, the commander who noticed that I was making a strange expression called out.

I apologize for stopping everyone's feet because it was not a big deal, but it was also the limit of patience.

Let's be honest here and let the commander sweeten your words.

It was when I lowered my head to everybody and put my hand against the wall to take off my shoes.

At the same time as I suddenly heard an unpleasant sound, my body leaned.

Eh!

"Sai!!"

Looking at the wall in a hurry, I saw the slab of wood that had been punched off and a hole in it.

And the body that lost its support was thrown into a dark space.
