A group of adventurers, torches in hand, walk down a low-ceilinged tunnel.
Eventually, they came to a dead end.

'What the hell, it's a dead end!

The leader of the warriors kicked the wall of the dead end in frustration.
As a large man, he had to stoop down to explore due to the low ceiling, and the more he explored, the more stressed he became.

And so did his companions, who were taken aback by his behavior.
The bandit man clicks his tongue at the leader of the warriors.

'Shut up and stop ranting. That's why I said right earlier. You're the one who decided to go left.'

'Huh? You're saying it's my fault?

'That's what I said, but it sounded different?

'Don't split up in here. ......'

The sorcerer man intervened, but he was also a snake.
The warrior's frustration was directed at the sorcerer.

'Whose fault is it that I'm so irritated! It's because you're embarrassing me in front of my clients!

'Huh? Don't be so accusatory. Then why didn't you answer?

'What are you talking about? There's no way I'd know about a monster I've never seen. That kind of knowledge is the responsibility of the sorcerer, of course. In fact, that sorcerer-like gentleman was able to answer.

'You know, if you had ......, you would've just known by chance. How many monsters do you think there are in the world? It's doubtful that even a diligent student graduating from a magic academy would be able to memorize all of their characteristics. Normally, you have to go to the library and do some research before you go.

'Then why didn't you look it up?

'Huh? I've been telling you for a long time that you need money to use the library, haven't I? Who was the one who dismissed it as a waste of money?

'Ngggg ......! Oh my god, you're so annoying!

The warrior, at a loss for a response, kicked the wall again in frustration.
Then...

Gogo gogo gogo. .......
A sound like the rumbling of the earth could be heard from somewhere.

Hearing the sound, the men who had been arguing with each other gather together in fear.

'Oh, hey, ...... you kicked him too hard, didn't you ......?

'Hey, idiot, no matter how much I kick the ground, it won't look like this.

'That means ......'.

The men looked around the tunnel.
The gray rock cave was a dead end in front of them, and behind them was the path they had taken, with no other path of any kind.
There is a fork in the road a few dozen meters back, but...

'Shh, shh, shh, isn't it close ......? Where are you coming from, ......?

'You idiot, I don't give a shit!

'Aaaaah!

At that moment, the sorcerer man shouted loudly.
The warrior, the bandit, and the priest all jumped up.

'What's with the sudden shouting?

'Alert ......! I should have used the alert ......!

'What the hell is that? Is that magic?

'The one that notices when a monster enters within 50 meters!

'What the hell? You idiot! If there's such a thing, why didn't you use it?

'It can't be helped that I didn't think of it! You guys always treat me like I'm useless if I don't leave any mana for attack magic!

I'm not sure what to do. I'm not going to use it now.

'There's no point in using it now! The alert only reacts when you come within range, and even if you use it when you're already within range, it's still ......!

I don't know about you, but you're really useless!

'What the hell is wrong with you?

'This is not the time for you idiots to be fighting...'

This time, the bandit intervenes, but then...

Gong!
The rock wall that was supposed to be a dead end suddenly collapsed, and a huge hole opened up.

'What the heck is ......?

As the adventurers looked at it with trepidation...

Then...
From the other side of the big hole, something like a huge moving rock with a diameter as tall as a man emerged.

It has no eyes or anything.
But in the center of it, slightly downward, there was a streak running horizontally, like a gap between rocks...

It opened up and down in front of the men's eyes.

Sharp teeth lined up in a row.
When the mucus that dripped like saliva splashed out, the rock surface of the cave made a sizzling sound and emitted white smoke, and a hole appeared there.

It was the head of a monster called a rock worm that came out of the hole and opened its big mouth.



The screams of the men echoed through the mine.
