The Adventure was flying at sea, aiming for an ice-covered continent.

I sat in the captain's seat and the cockpit had Early on it.... I'd be surprised if you thought about letting the princess grip the joystick. Because it's her hobby.

"But Jin, why is it a Northern Continental ruin?

Early to say strangely. I manipulated the console to display the world map on the screen.

"The Ice Continent is close to the Great Empire. Once engaged, massive reinforcements are sent in quickly. I just want to put Keri on before that happens."

"I see."

"According to SS Intelligence, the Empire has already sent an investigation team and escort,"

Observers and reconnaissance pods are reporting local footage. The ground forces of the Great Empire will be searching for the land of ice, where the ruins seem to be.

Early shouted "Wow".

"Fine, that's a lot of them."

Multiple tents have been erected to serve as base camps. There will be more than a thousand people out there in the empire alone.

There are other magical civilization weapon frigates and tanks on the escort. Are you assuming the Imperial Army would have ruins in the basement, or were trying to dig a hole?

"This one knows the underground passage to the ruins. Keep going straight to the World Tree."

This one leads the way on the shortest route while the Empires work hard to locate the ruins.

"But, Jin. Surely the ruins here weren't the roots of the world tree at the bottom of the ocean? Can you dive in the Adventure?

"Asahi would be fine. But it's no problem, Early. Because Aletti knows the route from the World Tree to the ruins below."

I turn my gaze to the silver-haired girl in the navigation seat. She also looked back.

"Yes, Father. The World Tree has an underground and incoming transfer team, so we can get inside on this ship."

Yeah, you don't have to dive into the ocean to let me in.

Previously, when Reele and Habara investigated, they only knew roughly, but they were good at identifying the location of the world tree.

While avoiding drifting ice, the Adventure flies near the sea level.

"Oh, I see it"

coastline of the ice continent. It's like a cliff. Plus, there's one hole that seems like a giant cave.

"Human-sized, no. It's a big hole in an AS or a demon machine, but if it's the Adventure, it's cynical."

"If you're not sure, shall I take your place, Early?

"I'm a fighter pilot, too. Compared to penetrating the canyon at a fierce speed, I'm fine! I think..."

Did I say the last thing that makes you so anxious? About my daughter-in-law calling herself a celebrity in cursive flying.

"... Early?

"I'm coming!

The Adventure speeds up… without, rather, lowering and switching to flight by floating magic, it broke into a cliff hole.

If you slow down, it's normal to lose lift and fall, but floating stone-mounted aircraft, basically, 'don't crash'. Therefore, even cramped caves for small craft can be safely maneuvered through....... Still few critical places though.

"Divine!"

"Compliments are nothing."

Or something like that, but I can illuminate it, Mr. Early. The Adventure jumps through the ice and rock caves. Though at low speeds, her brains and maneuvering arms are truly excellent. Even if it is illuminating the front with lighting, it will not come into contact or it will be shiny.

Cancer, and the contact sounded. The SS-made Verde on the console reported administratively.

"Starboard, shield in contact."

Well, you didn't hit it.

In the words Early returned, the gaze of everyone in Cockpit focused on her, including me.

"... if you hit the shield, you didn't hit the hull. Right?"

The shield of magic that protects the hull unfolds its protective membrane about a few dozen centimeters away.

"Oh, sure, it didn't hit the 'hull'"

I smiled bitterly.

"So, is there anything else?

"No, there's nothing."

Early concentrates on maneuvering.... If it hadn't been for the defensive shield, maybe we would have been in contact? I thought so, but I kept quiet.

The Adventure, which continued to advance through a serpent-like, linear cavity, eventually went out into a wide space.

"... it's a world tree"

The great tree with its icy leaves, the part above it, is out of the sea. But other than that, it's submerged in the ocean. It's horrible to think that this is here for 10,000 years or thousands of years without rotting.

Either way, we arrived at the point we were aiming for.

"Areti?"

"I will direct you"

The silver-haired girl who took her seat went to Early in the cockpit. I glanced and pointed at the view I could see from there.

"Over there."

Copy that.

The Adventure slipped between the branches of the world tree and moved to the underground transfer formation.

Ahead through the branches, there was a platform and the Adventure landed there. A few seconds after Aletti went outside and found the operating terminal, we were inside a structure that seemed to be inside the building.

It is a metastatic formation. That's magical civilization.

Get off the ship and call for a follow-on collection unit on the portal. Mr Daska, Yuna, the Olivia Kingsguard and a group of SS soldiers came on floating motorcycles and Dezelt II troop carriers.

"I don't think there's anything, but be on your guard"

I give instructions. If you look at Areti, she was operating a nearby access terminal.

Father, this facility is still alive.

"Can you get a visual?

"Yeah."

Aletti manipulates the magical civilization-era equipment without difficulty. The shape of the keyboard is not a corner shape from the era of mechanical civilization, but a design with a wide variety of triangles and circles. Early and Daska also stare at the holographically displayed maps.

"This is island seven, isn't it? islands where residential compartments are taken more widely than factory facilities"

Aletti points to the map.

The overall silhouette is a gravy boat - an island shaped like a saucepod pouring curry loo. The world tree stands on the back side if it is to be in front of a thin part of the shape like a pour.

"The control facility is just halfway between the tip and the world tree, this outpouring part. Military ports and facilities are concentrated in the previous area."

"You're quite a distance away"

Mr Daska said, extrapolating the overall size from the size of the world tree. Probably about ten kilometers from here.

"It's okay. There are multiple military transfer formations in the facility. With a keycard, it won't take much longer."

Aletti's words were reliable. I held the key card I kept from Reele in my hand.

"Let's move to a room with a transfer team first."
