After crossing the bridge, we go further into the cave.

The cave is still a gentle uphill slope.

"Hey, Marina, are you Captain Mithrill? What kind of treasure did the pirate leave behind? The gold and silver treasure?

When Rio called, Marina shook her index finger and replied.

"Shh shh shh, Rio, you don't have to know what's waiting for you. If you knew what the treasure was from the beginning, would you be interested?

"Er, but, you know, I've been trying to find something, but if it's not that big, you'll be disappointed."

"I don't know if it's romantic, including that. ─ ─ Ah, maybe it contains a love medicine that immediately makes the person who took it fall in love with the person in front of you.

"" Eh...?

Damn it... damn it...

Our teachers start groaning.

"Well, that works for everyone!?"

"For example, even for such a dull person....!

"... Rio, England, calm down.... on the contrary, there is a way for us to pretend to have drunk it.... in that case, it's because of the medicine that I can't help it."

I see! Mayfa, you're smart!

Yeah, I don't know, but the three of you, including Mayfa, are gonna calm down.

I'm talking about something.

I'll tell the kids with a bitter smile.

"The Captain Mythrill treasure I've found so far seems to contain a lot of gold and silver treasure, plus some powerful original magic tools. It seems to be in a magnificent chest like the one pictured."

"Ah, Mr. Brett, don't say that!... I don't know, even though you're not a pirate. Were you a pirate once?

"I didn't do it. I'm only interested in brave miscellaneous studies."

The legendary pirate Captain Mythrill is a mysterious figure, but he is also a super celebrity with a fairly high name as a famous brave man in history.

He was also seen as the greatest brave man of his time, and all the pirates he brought with him were no less powerful.

It is also said that it was the Captain Mythrill who created the image of pirates crouching the world's oceans for treasure hunting and romance, such as the Marinas.

Before that, pirates were referring exclusively to the Dark Warriors of the Sea who attacked innocent ships and looted them.

And as we went through the cave with such a chat, the road eventually turned right to the left hand, and from there the road went down slightly steeply.

"Everybody, be careful, your feet are slipping a little."

"" "Yes" "

When I noticed, Marina and Argna responded well mixed with our teachers.

It's starting to look like an excursion.

That was when we went down the long downhill road for a while.

─ ─ Clicking.

The sound of some sort of switch was heard at the foot of the leading marina.

"Nh...? It just kind of clicked..."

As Marina gently raised her legs, there was a slightly more concave ground than her surroundings.

Apparently, it was not a natural topography, but a trick obviously obtained by people.

And then...

─ ─ Gagoooooooooon!

On the road behind us, I heard something big and heavy fall from above.

Turning around, what was ahead ─ ─

What a classic trick.

"... oh!... oniisan, look, the rolling rock (rolling stone)!"

Mayfa sneaks in, pointing to the end of the ramp where they descend.

From the tip of the ramp, huge round rocks were rolling towards us.

Logo, logo, logo...!

It gradually increases its speed, and eventually it rolls down the ramp at a fierce speed.

Incidentally, the big rock is about twice the diameter of my back.

If that rolls at that speed, one of the dwellings will easily become a mess.

"Yaba, really...! ─ ─ What are you doing, Mr. Brett? We need to get out of here or we're gonna get crushed!

"Rio, Iris, Mayfa, hurry up!

Marina and Argna rushed down the ramp, but seemed confused to see us not moving.

By the way, Mayfa shows his willingness to agree with both of them.

"... yeah, I know.... niisan, let's run.... it's polite to run away in a hurry."

"Courtesy is you.... Well, no. Rio, England, let's do it."

"Aye, brother!

"Yes, Doctor!

"... no, oniisan, that's no good...!... I'm so sorry for the Captain Mithrill...!

Ignore the hard-working Mayfa.

When Rio and I stand in front of the rolling rock, England activates magic behind it.

"Rio, let's go ─ ─ [Earth's Rigidity (Earth Might)]!"

There was a magical glow in Rio's body, exercised by England.

In front of Rio and me, the big rock rolled down at such a fast pace ─ ─

"─ ─ Haaaa!

─ ─ Zdhhhhhhhhhh!

There are roars in the area.

Slowly, the sand falls from the ceiling.

Me and Rio were catching the rolling rock by the two of us.

My feet slipped slightly, but I managed to kill the momentum by being pushed one step or the other.

Behind us, Marina and Argna are squeaking their mouths.

"Uhhhhhh...!?"

"Ah, I'll catch that... that sort of thing..."

And it's Mayfa who slaps me in the face.

"... oniisan's idiot...! Stupid, stupid...!... the rolling rock (rolling stone) is not like the rolling rock (rolling stone) if you don't run away in a hurry...!

It is the specification that makes the point that only one person is strange.

I don't know what Mayfa is saying, but unfortunately safety is the first priority.

Marina, Argna, come back up a little bit.

"Ha, yes..."

Two brave men who had been running down a long way and followed my instructions honestly.

Confirm that and I'll signal Rio.

All right, let's go, Rio.

Hoisa, brother

Sei-no!

Rio and I both lifted the big rock and threw it under the aisle.

The big rock, which landed again with a roar, rolled down the downhill road and eventually stopped moving with a water noise.

Looks like this downhill is a water field.

"Hmm...."

Marina and Argna looked at the end of the big rock in a gloomy manner.

Even if you look at them like this, they're very similar.

"You did it, brother!

"Doctor, you did it!

Nh, well done, both of you.

Rio and England raise their hands, so they're in turn hitting high.

Then, when they put their heads on as usual, they nostalgically missed each other as usual.

Very cute.

"... slimy"

Meanwhile, Mayfa was the only one who seemed to regret it.

As always, I'm not sure where to focus.

Anyway, when we attack the rolling rock (rolling stone) in this way, we go further into the cave.

Just in front of the water field where the big rock jumped in, there is a sidewalk on the right hand side, and it will take a while to go there.

Eventually...

"Brother, look at the light outside!

Beyond the path Rio pointed to, something like a cave exit appeared.
