Beyond the sinus of the world tree, something glistened.

As I peered into the trunk of the world tree with my mouth fully open, I saw something about five mertes in position, a burst of intricately curved "tree caves".

Sage Grecas, there's something in the back.

"Obviously not a tree. I wonder what it is? Let's have a look."

"I'll give it to you, too!

Makes me smile excitedly as Metius sits on my shoulder.

- Could it be a fragment of the Holy Sword Battleship?

I stepped out of a wooden rift into a cave to be driven by my gushing curiosity.

Inside, the entire wall emitted pale light, and there was a degree of brightness that was hard to tell the shape. Not that it's a complete dark world, but it doesn't seem like enough light to walk.

"Phosphorescent Magic (Will O Wisp), illuminate where you're going"

I emerged a "sphere of light" about the size of a grip, floating like a flutter pushing forward. As soon as the blue and white light illuminates the cave and the foot.

"Sage Grecas, this is tough if you get lost"

"Ah......!

The feet are gotten bitter like roots, and the cave walls and ceilings are folded together like trunks (...) texture.

The road is about a merte to two mertes, but when you look up, the ceiling is about three mertes tall and less compressive. The roads are branched and intersect steep downward and upward paths, paths leading horizontally.

From the entrance alone we can see the intricately intertwined spaces that continue to extend.

"Hmm, the exploration inside is going to take a while"

"Mr. Grey, Plum is going too -!

Pram came after me from behind there. Hemperoza seems confused at the entrance and says "Be careful -".

And then Pram grabbed my back.

"Plum, I'm just gonna take a look, you don't have to come"

"Don't you let your legs slip and fall -?

"Ugh... so is that"

Pram's imaginary worry (...) was largely understandable. I'm sure I slipped my legs and deep in the dark I said, "Whoa!?" and you think you're going to slip by the dusk.

Well..., I can't say there isn't.

I grabbed Pram's little hand. It's been a long time since we've held hands alone. Sook...... I think my palm has grown.

Going about five mertes back, half of the glittering stuff was buried in the wall. Shivering and observing, it also looked like a part of something hexagonal.

"It's still a piece of metal! Let's reclaim it for a bit."

I carefully checked the magic thread (Magiwire) to see if there was any danger before touching my hand.

In case it was actually an ancient magic weapon... because it wouldn't be stylish if something happened.

"Heh... heh!

"Ooh! I got it!

While me and Plum were pulling and pushing a few times, the metal pieces that were buried got polarized.

The metal pieces, about 20 cm in size and 1 cm thick Merte, have a beautiful hexagonal shape.

It appears to be surprisingly light and made of strange metals or alloys.

The surface is rugged and dull silver. On the back there is a fine hive-like carving; on the six corners there was a triangular protrusion. Is it for coupling with some kind of hardware? It seemed to be part of the interior parts, not the exterior armor etc.

"Greg, is this a treasure?

Look at my reaction. Plum blinks at me strangely.

"hehe, some people might be more than treasure (...)"

It would be the Magic Society of the Kingdom, the Royal Army, or a bunch of craftsmen who produce weapons and magic tools in the city who are wanting to get pieces of the Holy Sword Battleship and are wussing it.

Plus, you can add Marino Serese extremist groups.

This would undoubtedly be traded for a pretty high price as a special research material. 100 goldo or no 300...... given the scarcity, maybe more......

"Well, sage Grecas, that's a face that's already been calculated for selling (...)"

The fairy Metius stared at my face as she danced in the air. They instantly cut out fairies I've known for a long time, such as in my mind.

"Nah!? I don't know what to say, Meti, people are not listening."

"Oh, I thought you were gonna sell on the dark route through Mr. Dwarf, the driller."

"Ko, because I give this to Chikin and Sir Rembrandt!? And don't worry."

I'm sure my mind has shaken slightly, but it's "at work" for once.

I went back to where everyone was resting, and I said, "Look at that piece of metal I found! It's a fragment of the Holy Sword Battleship! Awesome!?," he showed off.

But I didn't react well.

"Heh?"

"Plate cut. Right?

"Is this all...?

Hmmm, I figured I'd sell it secretly......

Even as we stopped by like that, we had climbed the inside of the world tree smoothly and, if we noticed, had reached near 500 Merte from the ground.

It's been about three hours since we left the ground, but it'll be a good pace.

The time goes around 10 a.m., and the light that plugs from the ceiling of the world tree lights up the area more and more brightly.

When I looked up, I saw a green light lid (lid) about the same size as the sun. There must be a hole in the edge of the sky.

On the contrary, a peek directly underneath, the bottom of the hole was dark and invisible to nothing.

"I've climbed a long time..."

"Top of the line. You're almost there!

Manuferno seems to be getting excited too. I'm really excited about what's at the top.

"But, hey, when you climb, you're going down, right?

And that's where Hemperoza asked as she hung her dark hair in her ear with her fingers.

"I didn't get ready to sleep upstairs. We have to be back by evening."

The first investigation ends today. We're flying back to Finovocchi village at night.

"I'm walking on a chisel."

"No, because this time you're the least walking..."

"I'm tired of just doing this for you!

Hemperoza gave a slightly tired grin as she gently stretched out the spreading magic (Shrub Garden). Looks like I'm getting tired of boulders.

Shall I at least carry him home......

"Are you going down this glue hole again..."

The boulder lu also looks down and laughs bitterly.

Four hours, including a slow rest to ascend. Then I guess I thought the same way down.

"Huffle. I'm thinking there."

I lifted my fingertips when I put on my glasses.

Everybody's got their attention on me.

"What do you think I brought this' full 'and' blurb 'for?

Bang, and slap the back of the barrel.

"What... ah!? No way."

Lentomia raised her elf ears and narrowed her jade eyes half-eyed.

"I have a hunch. I don't like it... I only have a hunch"

Manu has a tight laugh.

"Nha...... ah!? Are you kidding me?

Lu blues sassy.

"Yes! From the top of the world tree we grab 'full' and 'blurb' and dive! Full force reverse injection where you fell free to near 300 Merte on the ground! And then slowly down to the ground... an operation!

"Don't like it!

"Me neither. Yikes!

"Don't hesitate!

"Resolute. You refuse..."

"Plum is flat...... I'm a little scared -"

"Ugh... right"

Until brilliant unanimity. The great return operation was vetoed with all its might.

and a warning popped up on the tactical information display (tactics).

"Colour?"

- Emergency information and communication? Garrison base... from Sir Rembrandt.

"Master Sage! Immediately, circular!

"Sir Rembrandt, what is it?

I could hear him looking pretty panicked. Communication status is not good because it is in the world tree.

Golem! Two example Tarantia, up the outside of the world tree (...)!

"Hey, what!?
