The "continental shelf" refers to the topography of the seabed, from where the seabed slopes slowly to a certain distance from land to where it suddenly deepens.

The fact that there is a continental shelf here means that the archipelago of the wise is quite far away and on a different continental plate... what a thought I have, but it doesn't matter now.

I explained the entire continental shelf, but Ms. Dantes said, "with the face of his neck,

"Reggie, I've never heard of the continental shelf. How's the mayor?

"The depth of water around where the seaboy was seen is well over 100 meters and we don't know how deep it is. So the underwater topography is unknown."

"Ah...."

Well, that's true. I can't find out what the topography of the ocean floor is like.

There are no underwater explorers in this world, and of course there are no ultrasonic measuring instruments.

"But... I've heard stories that fish species can change in the waters around here. Isn't it?

And the mayor asked the knights, but most of them felt like "I don't know," and a young knight raised his hand.

"My grandfather is a fisherman, but he said," The seaboy doesn't come to the port because the food is different. "

"... that's the first time I've heard of it, but I don't think I've ever heard of it in my report."

"Hey, Mayor, Grandpa's remarks have to be taken seriously... because I don't know what kind of monster the seaboy is in the first place, but I don't even know what he's eating."

"Hmm... I see. Your grandfather must have a wonderful fisherman's instinct."

"Yes, I'm afraid so."

"--Lord Reggie. I've never heard of a place called the continental shelf, but will the ecosystem of the fish that inhabit it change?

I desperately recall my knowledge when I was in Japan. [M]

"Uh, yes, maybe. The existence of the continental shelf should also change the movement of the current, so I think not only the habitat of fish but also the season when migrating fish visit will change."

"Hmm... so the seaboy appears on the continental shelf off the coast of Zucker Halfen for prey?

"... possibly. But I guess...."

It was when I tried to talk about another possibility.

"--Mayor! I've got a magic ship ahead!

I heard the knight under surveillance.

"In battle!! I'm fighting someone!!"

It was hard to believe immediately that the small dots that appeared on the horizon were the magic boats we were chasing - Lark's, but I didn't know what to expect.

The water is splashing brightly.

It was uncertain whether it was an attack from a magic ship or an attack from the sea floor.

"Would you like to go faster!?"

"This is the full speed...!

I called the knight in the steering bay, but he said he was already as fast as he could.

When I jumped onto the deck and headed to the berth, Zelly was there.

"Boy."

"Zelly, can you see me?

"Somehow."

Zelly's mouth, which was drunk on the boat, was dirty with something sparkly, but she didn't feel like sticking it in.

Zelly has better eyes than me. [M] Even though I am absorbing my talent, I sometimes see Zeli better, and I'm sure it's a species trait called a cat beast.

"... that sucks."

Zelly, who was staring at her forehead, said.

"Oh, I'm not fighting. He's on the run!

"Eh--"

Is that so?

It was strange that I caught up with Lark's magic ship, which was supposed to be a day ahead, but I ran into a seaboy and turned around and ran off to the coast.

Something like a green tentacle jumped up with a sharp splash of water. Although the direct hit was avoided, the magic ship was shaking.

"Seaboy... that's it!?"

I doubted my eyes. [M]

The magic ship heading towards us from the coast was running in a dark sea. I thought it was just a change in the color of the ocean —— a huge shadow.

Suppose all of them are sea bastards.

It's big enough to swallow up an entire village or town.

(How do I fight such a thing!? An enemy in the sea!?)

I can see the magic ship clearly. They also noticed us, and somebody on deck waved a white flag without saying "run." There, the waves rose, the magic ship swayed, and the white flag danced to the sky.

The tentacles are stretching. If you get caught, it's over.

"Ah--"

The black blade slams and rips the tentacle open.

"... you idiot! Bacalark!!"

I didn't hesitate to use Shadow King Magic Sword . Don't you understand that talent is what keeps you from losing it? Do you use it even if you understand it? Either way-- stupid.

"I can't get any closer! Fall back, Mayor!

"But...."

"You'll catch up while you spin!?"

Uhm

In the back, the mayor was crowded with knights.

The knights are right. I don't think I can handle that giant creature with the equipment on board.

"Mayor--"

I said.

"Please turn back."

"Baby, that 's--"

Zelly, who was sitting beside her, looked faint.

But what I tried to say was a little different from what Zelly thought. [M]

"Please turn around. I will fly alone to the other magic ship (...)."

I developed Fire Magic and Wind Magic .
