After Nao entered the hole that Rock Worm dug, Sharia and the others, as Nao told them, split into the left and right of the hole and watched the front and back of the tunnel.

The slightly deflated air turns around, and there are sometimes signs of a real threat in front of them, and there is no relaxation between them.

Instead, however, there is a sense of anxiety.

Regardless of the long-standing relationship between Mary and Meetings, Sharia and the three of them sometimes look back at the hole and look worried.

"... hey, are you sure Nao was okay by himself?"

"I don't know. We don't know Rock Worm well either...."

"It's a reflection. We didn't have enough research."

"It wasn't on the original request form."

Mary said and followed Sharia, who breathed deeply, but Tania slowly shook her head.

"But I knew about Meatier."

"In our case, Nao-san and I have a monster encyclopedia..."

As Mary lowered her eyebrows and buttocks, she followed again.

To be precise, the volume containing the sea monsters is missing, but it covers most of the known monsters encountered in this country.

It is an undeniable fact that Mary's learning environment is quite favourable because she is free to read it at any time.

"Oh yeah, I knew I was with a high rank..."

"I can look into it in the Adventurer Alliance! It's easy!"

………

Meetings cut off Mary's followers and silenced Sharia and the others.

And then I chased him even further.

"Oniichan said he was doing his best in the Adventurers Guild in the first place!"

………

If Meatier was older, she would have a little excuse for herself, but she was actually over five years old.

Sharia and the others could not say anything because they understood that the age difference was huge and that there was room for us to work on it because the rank was high and the environment was good.

"I can't leave without trying.And knowledge is also the power of adventurers! "

Funny! Funny! Mary also gave up following and gave up laughing bitterly to her rough nose and breath.

"Well, there's no doubt that Nao-san and the others are very hard-working.I read quite a few books, and I think it's because of the healing magic, but I also do training that can cause serious injuries every day. "

"... is that the same with Mary?"

"We don't get hurt much."

"Compared to Nao-san, it's weak.Even if we do everything we can, Nao-san and I can afford to edge properly. "

"But you're training hard enough for that, right?"

"Of course, I think that's a natural thing to do."

"When I get stronger, I'm not afraid of anything!"

In fact, they worked pretty hard.

Considering their age, Nao people were getting a little worse, but despite the age at which they wanted to play, they would never participate in training, nor would they cry.

I don't know, super stoic.

When I first met him, he said, "I want to be fed," but I can only think of him as aiming for an independent woman.

From Nao's point of view, it was a little worrying, but given the severity of the world, I could not stop because I could understand the feelings of both of them.

And their hard work has also been a driving force for Nao and others to continue their efforts.

"I see. We need to work harder too!I might have been a little proud of my grades in the dojo. "

"That's right, I was relieved to hear the best thing about synchronization."

"I'm going to train more times!If you like, I want Mary and the others to train together! "

"I don't know how long I'll be in Valm Grey, but it would be nice if I had time.Nao-san is also very popular, so I think he will go out with me if you ask him.When I settle down, I think I'll start training here in the morning. "

"... yeah, it's backed by training. I'm sure if it's Nao..."

Dogan!

Gogogogogo!!

Suddenly, the sound of an explosion and something collapsing came from inside the hole.

Obviously some sort of combat noise.

The sound, unlikely to occur if Sharia and the others fought, aroused anxiety among them, and the three looked at each other in dismay.

"Hey! It's really okay!?"

"It's making a great noise!"

"It's okay, if Nao-san isn't okay...."

What if I don't?

Mary answered Argna's question with clear eyes.

"I give up."

"Give up early!?"

"That's all I can trust.Without Nao-san, neither I nor I would be alive. "

"... is that so?"

"Yes, they picked me up where I was dying."

Mary nods to Sharia, who answers surprisingly.

"I was an adventurer that year, so I thought there was something there ~"

"It was Nao who cured my wounds, put clothes and shelter on, and trained me as adventurers."

"If oniichan gets caught up with you, everything will be fine!"

Meettia's words seem to be blind, but if you ask the adventurers around you a little bit, you'll soon know how blessed they are.

Never before, at least, have Nao and the others failed to live up to Meatier's trust.

"So I think we should just wait and see."

"Okay, we'll trust you and wait."

And the explosion stopped for a while.

Slurp, slurp.

I heard something heavy crawling through the ground from inside the hole.

Eventually, it appeared from there.

◇ ◇ ◇

"Phew, that was tough..."

Nao!

As I crawled out of the hole and raised my face with a big breath, for some reason Sharia stood with her weapons around me.

"Hmm? What's wrong? Should we be alert to the left and right passages?"

In that regard, Mary and Meatier passed because they had weapons on the side of the aisle while looking at us.

We should be vigilant, too, but we shouldn't stray from the aisle.

There is a danger that enemies will come from you.

"I mean, it sounds suspicious!I care! "

"That's right. I wonder what's approaching."

I bowed my head to the two of them who shook their hands to protest.

"Suspicious sound...? Ah, this is it.Just fine, just take it. "

When I pressed the end of the rope I had in my hand against Argna, I stretched my hips and relieved (loosened) my body.

"Ouch! I thought my hips and knees were going to die!"

"Were you attacked!? Are you all right?"

"Ah, no, it's just that I've been bending all along.It's really hard to travel long distances in the middle waist? "

If you think it's a lie, try it.

There is a tunnel-shaped plaything in the park that uses sewers.

How tough it is to travel hundreds of meters in this adult body when you're a kid!

"... how about a fight?"

"Especially you. It was a magic shot."

Thanks to the advance of Light, we were able to discover the Rock Worm with considerable room, and more conveniently, he turned his head towards us.

All you have to do is throw a 'fire ball' in your mouth.

Rock Worm blew his head off without escape.

The calculation was somewhat incorrect because it was closed or because the Fireball was more powerful than expected.

I was supposed to be close enough, but the blast and the stone fragments flew all the way to where I was, and the surrounding walls collapsed a little.

Fortunately in misfortune, the fragments of the Rock Worm did not fly, so the slippery things were avoided, but it was a little difficult to clean up.

"I'm glad you didn't get hurt ~"

Sharia and the others look relieved by my words and the fact that they don't seem to get hurt.

"I was worried because of the sound of collapse."

"And then there's the noise of crawling."

"That's the rope.It's not a souvenir, but pull it. "

"What? Ha, yes... it's heavy!"

"Eh, what is this!? Nao, did you pull it alone? Do you want this?"

"Awesome! I can't believe it!"

Well, it was pretty heavy.

I guess I managed because I had Strength Enhancement skills.

Argna could barely pull herself, and Sharia and Tania could help immediately, but finally.

Once again, I began to hear the heavy noise that had been echoing until just now, which eventually made me peek at my face.
