On March 4, Jin, together with Erza, Licia, and others, had come to the Demon Territory...... or <>.
It was to send Zion and Marikka, whom he had invited to the Dolls' Festival the previous day, on their way.
Or, more precisely, to observe the paving method of the <>.
"Hey, it's nice."
"You don't have to be so hard on yourself, Zion, it wasn't your idea."
Now Jin, together with Zion and Zion's mother, Rorona of Morura, had come to the village square.
"But I was surprised. I thought you knew everything.
"That's not true. There are many things in this world that I don't know.
You are very humble.
"More importantly, how to pave this place ......"
I happened to mention in front of Zion and Maricka that a road was going to run through to the village of Lycia and that it would be nice if it was paved,
He muttered something along the lines of "It would be nice to pave it. "Can't you just put gravel on the road and pave it?"
I heard Zion say,
"Well, if you put crushed gravel on the ground and push it into the ground, it will harden. I don't know why ......."
I don't know why," I heard Maricka say.
I know a lot about making things, but I'm an amateur in the field of civil engineering.
Lorona explains to me. She had some background in civil engineering as well as agriculture.
"This pavement is made by breaking rocks, scattering the broken stones, and then hardening them.
Lorona thought and thought as she explained.
"Well, I heard from an older colleague that when the crushed stones are pushed together, they engage tightly with each other due to friction or something.
It is said that water is sometimes sprinkled on the stones.
This method corresponds to what is known as "macadam paving" in modern Japan. It was often used before and during the war.
This method is effective because there are no heavy trailers, trucks, or dump trucks running on the road.
"I see, I get it."
Jin thought that if he named this method and spread the word about what he had learned from the northerners, it would be a good opportunity for them to be accepted.
"Licia, this is going to be useful, isn't it?"
"Yes, yes, yes!
It would have been nice if we could have brought Princess Rieschen with us, but it was not possible.
Since Reiko is with her, the information has been sent to the old man.
We'll have to try it out at Horai Island or Kunlun Island soon.
"Are you leaving already?"
Theon says in a frustrated tone.
"Oh, I'm sorry. I'll come back later.
He had reached the end of his rope with Lysia.
"I'm sorry.
Jin drove Licia back to Toka village by .

......Spring is almost here.
"Hmm."
Jin and Erza took a walk in the village of Kaina.
There were still patches of frozen snow here and there in the shade, but the roads and fields were already covered with soil.
The green buds of wheat were beginning to grow, indicating that spring was definitely on its way.
