"And this last one is probably the one you want to read the most. Here, the adventurer's record of explorations and battles.

Oren unlocked his desk drawer and pulled out a yellowing stack of papers.

More than thirty years ago, there was a hero who conquered the "Fearless Serpent Hole," a labyrinth created by the miasma.

The city named after him is the border town of Dadan.

Using this town as a base, adventurers begin their search deeper and deeper into the world.

Fighting monsters, they carve out a path through the forest and set up a stop along the banks of a muddy, blood-red stream.

They crossed the wilderness covered in sand and crossed blades with orcs.

The adventurers continue on smoothly toward the next maze of miasma, but only as far as the end of the wilderness.

What awaited them there were endless black swamps and monsters that had grown more vicious.

Still, they managed to wade through the mud, and what stood in their way was a white fog that ate away at their bodies.

The adventurers stood speechless at the sight of the huge monster looming beyond the thick fog.

And then, at the sight of the shadowy figure that looked just like an old woman, there was only one word that came out of their mouths.

"............ witch?"

--This is the moment when the name of the Witch of the Spooky Swamp was born.

Since it is impossible to reveal the true nature of this terrible monster, only the word has spread throughout the border town.

Whatever the name, there is no doubt that the witch is a formidable obstacle.

Determined, the candidates for the greatness of the time took up the challenge to the monster with great vigor.

But only one of them came back.

From there, the rumors of the Witch of the Swamp began to spread as a kidnapping presence, far removed from the reality.

"So that's how it happened."

"That's why there were no specific anecdotes about witches."

Thereafter, the adventurers who had come before us, while developing countermeasures, fought three battles. 

Needless to say, the outcome of the battles was not good when the witches were still alive and well.

"Some of the things that made it so, I should mention first of all the characteristic of awe..."

"ig?"

It means to inspire a strong fear. The records say that just looking directly at the witch up close caused her limbs to lose strength and she would shake uncontrollably."

Thor and Thora, who had an idea, looked back at the child who was silently looking up at the bookshelf.

Normally, the child would have climbed on the bookshelf by now, but today it was too quiet.

Perhaps the child's young age and his extra sensitivity had a strong influence on him.

When I held out my hand, the child came up to me silently and squeezed it back.

I picked him up and he buried his face in Thor's neck. 

"Next is the corrosive fog. It is said that when exposed to a high concentration, the whole body decomposes. It seems to be inferred that this is a dark technique.

"Dark techniques!"

Dark techniques are those used by subhumans who have been baptized by evil gods.

From this point of view, it is clear that it is not just a spirit type. 

"......This is beyond the level of nasty."

"Other descriptions include wielding a large staff and summoning giants and evil spirits. And that's not all."

Is there more?

"No, I don't. No sightings, to be exact.

"What do you mean?"

When Yuril tilts his head and raises his eyebrows a little, Oren reveals the truth.

"In all three battles, there has been no sign of a frenzy.

Thor's eyebrows lifted at this unexpected comment.

If the animal is a strong one, it should change its form to a frenzied phase with increased ferocity when it is damaged to a certain degree.

The fact that it has not shown such a change is...

"Either he has bottomless physical strength, or he has a disgusting amount of regenerative power."

"Based on the characteristics of the Mud Poison Titan, I'd say it's the latter."

"If even that Titan can't be defeated so easily, there's nothing we can do about it."

Without defeating the Titans, we will not be able to move up to the Vajrayana level.

On the other hand, if we defeat them without thinking, the witch will retaliate.

We were at a complete loss.

To Thor, who had fallen silent, the owner of the reference room continued to speak.

"I am glad to hear that you understand. It is our role here to correct the young man's recklessness. Please don't take it personally.

No, thank you for all your help. Thank you."

After thanking them, Thor and his friends leave the room full of bookshelves.

As soon as they were outside the door, Siegka, who had been waiting for them, came up to them.

"You don't look so good, Thor.

"Thank you for being so quick to guess. I really don't know what to do now.

Now, how about a little friendly conversation?

Thor's eyes move slightly at the offer, as if he had timed it perfectly.

Siecka noticed this and dismissed his doubts with a panicked voice.

No, no, don't get me wrong. I was told to bring this up with Mr. Thor when he came out of the reference room.

Thor asked sharply, his words becoming even more suspicious.

"Who told you that?"

"That, of course, is my former boss, as you well know, Master Thor."

Then, there is only one person I can think of.

Thinking of a certain person who was reliable but reluctant to meet with him, Thor had no choice but to listen.

"It seems that you are listening to me. Well then..."

After a few minutes of listening, Thor and the others left the Adventurers' Bureau and headed for the outer gate.

As they approached the carriage parked by the gate, Moe, who was still clinging to Thor's neck, asked a small question.

"Hey, Thor..."

"What's wrong?"

"Are you going back to that mud-spattered place again?"

"Hmm, what's wrong?"

"Well, if that's the case, maybe Moo would like to have a good night."

Thor nodded firmly at the child who looked up at him.

He gently strokes the golden curls of her hair as he replies.

"I'm sorry, Moo. Next time I'll make sure you're aware of it. And don't worry. The swamp is closed for the time being.

True to their word, the horses were riding not east toward the supposed noxious gas, but north.
