"Let's go to Tatsumi Bay first after we take a break for a while.

Jin mentioned the sightseeing plan of Horai Island.

"It looks like the fishponds have been finished, and seaweed and oysters are starting to grow.

We can take a boat ride," Jin said,

"Oh, I want to go on a battleship!

Rubina says. Jin smiles bitterly.

（Well, that's okay.)

Jin thought that if Rubina was having a good time, that was fine with him.

"We'll leave it to you, Jin-san.

He said this in a very modest manner.

* * * * * * * * * * * * * * * *

The trip to Tatsumi Bay was made by car. The driver was Hope.

The view of rice fields, orchards, and fields on either side of the road was a tourist attraction.

It has been five months since the beginning of the year. The fields and rice paddies that had been idle are now in operation again, and the orchards have been cleaned up.

"Well, the rice fields are beautiful.

Since Horai Island belongs to the subtropical zone, rice planting has already finished, and the rice paddies that have become a are a sight for sore eyes.

"Ah, an egret!"

Rubina shouted.

Her gaze fell on a white, long-necked, long-legged bird.

The one on Horai Island is a little egret. It is easily recognized by its crown feathers on the back of its head.

In fact, there is no heron whose official name is <.

<......< or is a generic name for white-colored egrets.

In addition to the little egret, there are also the chusagi and the great egret, but only the little egret was found on Horai-jima Island.

"They are probably looking for loaches or frogs in the rice paddies."

Because no pesticides are used, the island is home to many such small animals.

Pests are removed by hand as soon as they are found. Topaz and the others.

Diseases were prevented by using sterilization.

"Well, this is an advanced farming method, isn't it?"

Jin explained, and Ellis nodded his head in admiration.

"I think this is the only place in the world where you can get rid of pests <>by hand."

The 100 golem maids of Topaz in charge of agriculture, and sometimes land troops, craftsmen (Smith), little craftsmen (Smith), and mini-craftsmen (Smith) were also sent out to do the work.

This is certainly the only place in the world where such unprofitable farming is practiced.

Beyond the rice paddies, there are wheat fields and orchards.

White flowers of citran (orange) were blooming and beautiful butterflies were dancing.

But swallowtail butterfly larvae eat citran leaves, right?

So you have to thin out the leaves moderately or you will lose them, Jin said.

"Oh, dear, you leave a few instead of taking all of them. That's very kind of you."

"Yes, well."

Yes, well," Jin replied, "I'll miss the butterflies.

The car carrying the group drove down a gentle slope and approached the seaside. The scent of the sea wafted through the air.

Oh, that's the sea. I saw it once when I was ...... young."

The Kingdom of Klein has no sea, so you can't see the sea unless you travel abroad.

"It's beautiful. ......"

Ellis gazed at the sea, which was getting closer and closer.

"Well, straight ahead is the beach, to the right is the fish pond, and to the left is the harbor. Let's start with the fish tank. Hope, please."

Yes, sir.

At the three-way intersection, turn right first.

"There is a fish pond ahead, where fish are farmed. We call it aquaculture, but it's more like keeping a specific kind of fish in the bay with nets and boundaries.

Jin explained politely.

"That's a very large scale aquaculture!"

Freddy was indeed surprised.

"If we have too many, we can release them.

"Oh, yes, that's right.

Yes, we release them as needed so that we don't have too many to eat.

Unlike fruits and grains, living things cannot be preserved.

After that, we watched the seaweed and oyster cultivation, and headed toward the beach along the sea. Our destination was the harbor.

The car carrying Jin and his group was coming to the port of Tatsumi Bay.

The water here is so deep that even a 200-meter class battleship can easily navigate.

The battleship is now anchored in the harbor.

"...... is this ...... the ...... ship?"

Freddy exclaimed as he saw for the first time in his life a 200 meter long all-metal ship.

"My goodness, you built this too, Jin-san!　That's amazing!"

Ellis, on the other hand, had a twinkle in his eye.

"Would you like to try it?"

"Yes, by all means!"

Ellis was the most excited of the group.

Freddy was looking at him with a complicated expression on his face.

"Oh, so this is how it's going to be!

Rubina was also excited, running around the deck, peeking inside the ship and asking questions to the mariners there.

Ellis, on the other hand, was standing near the bow, staring out to sea with a satisfied smile on his face.

Seeing this, Jin decided to take the <> out to sea instead of the planned <> excursion.

"Marine 5, get the Hotaka out of the water."

"Yes, Master."

At Jin's request, Hotaka leaves the harbor and slowly exits Tatsumi Bay.

"Wow, that's great!"

Rubina, who has been obsessed with the idea of riding on a battleship, is all excited. I guess she had been reserved the last time I invited her.

And Ellis was still standing near the bow.

"Mr. Ellis, would you like to go up on the bridge?"

"Yes, thank you. Yes, thank you.

So we all went up to the bridge. The higher up we were, the better the view was.

"Oh, the sea is so blue. And I've never known that the horizon is round."

Since the curvature of the arcs is greater than that of the earth, the roundness of the horizon becomes more apparent when you climb a little higher.

"Our current speed is 50 kilometers per hour.

The lack of knots in Ars makes me feel a little less like a sailor, but it makes it easier to understand.

"50 kilometers for a ship this size ...... must be amazing."

Whatever he sees or hears, it seems to tug at his heartstrings, and Ellis remains impressed.

< made a large turn in the open sea and returned to Horai Island.

When they arrived at the harbor and disembarked, Ellis looked up at and bowed.

"Thank you very much."

Jin was somewhat moved by this gesture.
