A sudden attack by a rockworm sent the adventurer men scurrying away from the dead-end wall.

The large mouth of the rockworm snapped at the spot where the men had been just before.
Fortunately, there was no one there anymore, but the giant rockworm, which had missed its target, crawled out of a large hole in the wall.

Meanwhile, the men watching from a short distance away were in a panic.

'Ow, ow! You'll die instantly if you're eaten by that thing! What kind of D-rank is that?

'Oh, calm down. It's not that fast. Just keep a cool head and you'll be fine.'

'Then why don't you come forward and do the wall! I can't dodge everything in such a small space!

'You've got to be kidding! If I slip for a second, it's over! That's right, you're wearing chainmail, you should be able to withstand at least one blow. You should stand in front. If you take damage, you can recover.

'Are you kidding me? Didn't you see that saliva? It melted the rock! It's chainmail...''

The adventurers had assumed that the attack would not reach them because they were a little far away, but the rock worm opened its large mouth and attacked, spitting out acid from it.
The warrior barely jumped out of the way to avoid it, and the acid splashed onto the ground where he was, gouging out the ground with smoke and sound.

At that time, the acid was also slightly caught in the chainmail worn by the warrior.
The iron chains used to weave the armor still emitted a cloud of white smoke, but they did not melt as much as the rocks, and the surface of the chains only lightly melted.
The quilted armor worn under the chainmail immediately melted and made holes in the armor. .......

The bandit saw this and pushed the warrior back.

I'm sure you'll be able to figure out what you need to do. It's not that easy. You've always been so arrogant, why don't you show us your good side at times like this? And if you run away here, you'll lose to that picnic guy, right?

'Gosh, ......! d*mn it, I get it! But you've got to cover me!

'''Okay!'''

The bandit, the sorcerer, and the priest give each other the thumbs up behind their backs.
Only at times like this were they in perfect harmony.

So the warrior stood in front of the adventurers, while the bandit, the sorcerer, and the priest covered them from behind.

Toward them, a huge rock worm approached, dragging its feet.
They were so large that two of them side by side would have filled the entire tunnel.

And then...

'Whoa, whoa, whoa, Magic Missile!

Bash, bash!
Two arrows of light released by the sorcerer exploded in front of the Rockworm.

The rock worm screamed.
The rockworm screamed.

'Did you do it?

'Of course not, look!

Despite the fact that the rock-like skin on the surface of the rockworm was somewhat peeled off and the flesh underneath was damaged, the rockworm came towards the adventurers, bobbing and weaving wildly.

'No way, it won't stop!

'd*mn it, you just pissed me off!

The bandit swears as he pulls out the dagger at his waist and throws it at Rockworm.
But that dagger...

'Now ......?

Crack!
The dagger was bounced off the rocky surface of the rockworm, and was unable to do any damage.

'd*mn it, ......! It's too hard! Hey, what are you slacking off on, sling?

'You can't use a sling on this low ceiling!

At the exchange between the bandit and the priest, the vanguard warrior clicks his tongue.

'd*mn, they're useless! Aaaaaaah!

The warrior slams his battle axe into the rampaging rockworm, just in time.

The warrior's battle axe.
The blade of the battle axe shatters the rock face of the rock worm and digs into the flesh beneath.

However, it was only the tip of the blade that bit into the rock worm's flesh, and it was hardly a fatal wound.
Due to the height of the ceiling, he could not swing down from directly above, so he had to use an unfamiliar side-knife blow, which inevitably lacked some power.

'd*mn it...ohhh!

The warrior, who was unable to stop the charge with a blow from his battle axe, was blown away by Rockworm's charge.
He rolled around on the ground, but somehow managed to stand up in front of his comrades.
The priest rushes to the side of the warrior, whose head is bleeding, and casts a healing spell.

'Gah ......! That hurts, dammit. ......!

'What are we going to do about that monster? Let's get out of here!

'I've already done some damage! Just a few more hits and we can do it! Let's do it!

'Oh, yeah!

They were D-rank adventurers, even if they were rotten.
They couldn't just give up on a quest that was nominally of a lower rank.
