The group left the town of Banyou and headed west along the highway. They had an early lunch in Croix and stayed overnight in Hatata.

The trip was only about 40 kilometers per day, but Reinhard was not in a hurry because he was already in his homeland.

In fact, he seemed to be regretting that the trip was coming to an end.

When he was stranded in Asund, he wanted to return to his homeland as soon as possible.

The town of Hatata was a busy town for a rural area, with many people coming and going as the roads crossed each other.

The spring sun was still high in the sky, and Jin was touring the city of Hatata with Reinhardt as his guide. Reiko was accompanying him in silence.

"Unlike yesterday in Banyú, there are many one-story houses in Hatata.

In Banyú, there were a few two-story houses here and there, but here in Hatta there were many one-story houses.

The roofs have small eaves, and to Jin's eyes, the roofs look very small. The windows were also small.

"Ah. "Yeah. Because there is too much land and the population is small. There's no need to build a two-story house.

You're right.

Although there is a lot of traffic due to the intersection of streets, the town itself is so large that the people are scattered, and as a result, the area appears deserted.

"There is not much rain around here. Yesterday, Banyú was close to the Divide River, so there was plenty of water, but around here you have to dig a very deep well to get water.

Hearing this, Jin understood why the roof was so small. When it rains a lot like in Japan, the roofs are bigger and the eaves are deeper.

"Oh, so that's why it's kind of dusty.

The windows are also small to prevent dust from entering.

"Well, yeah. One more thing,...... the food here is not very good."

Reinhardt looked disappointed.

We returned to the inn at around 4:00 p.m. after a day of touring the city with such talk.

"Welcome home.

The inn was an unusual two-story building. As is typical in this town, the grounds are large and the garden is spacious.

"I'll bring you your rinse now."

said the girl at the front door in a cheerful voice.

Rinse" means water and towels to wipe your face, hands, and feet when you come back from a day out in this dusty town.

A well had been dug beside the wide entrance hall of the inn, and water could be drawn from it with a pulley and a fishing bottle.

"Nsho, nsho..."

Seeing the girl working the entrance hall drawing water, Jin was reminded of the village of Kaina in the past. He had built the pump after seeing Hanna working so hard to fetch water.

Hannah was 8 years old at that time. Now, the child fetching water is about 12 or 3 years old. Jin watched the pumping without looking.

"Oh, no!"

The hand that was pulling the fishing bottle seemed to have slipped, and the pulley was spinning at a tremendous speed. Soon after, I heard the sound of water.

When pumping water into a fishing bottle with a pulley, it is difficult to stop the bottle from falling down by its own weight if your hand slips even once.

Sure enough, the girl's palms were red and chafed as she hurriedly grabbed the rope.

"I'm sorry!　I'll pump it again right now!

The girl said and pulled the fishing bottle again. Jin watched him, but when he saw that the bottle did not come up, he realized again that the well was quite deep, as Reinhardt had said earlier.

"Sorry I'm late. Here is your rinse, please."

A tub of water and a towel were offered. Jin and Reinhard took them silently and wiped their faces, necks, hands, and feet.

"Thank you. I feel refreshed."

Reinhardt said and handed the tip to the girl.

"Oh, thank you!"

Jin saw the look of joy on the girl's face as she received it, and realized that he did not have any money with him. Then..,

"Let me see your hand."

He takes the child's hand,

"<>".

and he cast a healing spell on her hand. His palm, which had been chafed and bleeding, was now clean.

"Oh, thank you for ......!

The girl must have been happy, because she bowed her head deeply, thanked Jin, and left with a bucket of water.

The room was a large room with separate bedrooms for each of us. Jin, Reinhard, Matheus, and Reinhard's butler Claude were in the same room.

Jin, who had something on his mind, called out to Reinhardt first.

"What's up, Jin?"

I need to talk to you."

Jin told Reinhardt about the pump he had built. It had been widely used in the Kingdom of Klein, but Reinhardt had never heard of it,

"I didn't know such a tool existed!　I am very interested in it, and I will cooperate with you.

He was very enthusiastic.

So Jin and Reinhardt went to see the innkeeper.

"Isn't this well deep?　Wouldn't you like to install a tool to make it easier to fetch water?"

In addition to Jin's persuasion, the name of Reinhardt, the creator of the <>, was quite famous in the Shoro Kingdom, and the innkeeper asked him to make a pump for him with a simple reply.

"Jin, are you on time?"

"Yes. Yes. The days are long.

After such an exchange, Jin ordered his golem, Steward, to fetch the materials.

"Hi."

Reinhardt looked at Steward who replied shortly and walked away, and said to Jin in a whisper.

"That golem is not as good as it looks, is it?"

This was an insight that only Reinhardt, who had known Jin for a certain length of time and had seen his works, could have come up with.

"Well, you know. "Well, you're right, Reinhardt."

Steward soon returns. He said he had a bronze figurine, and that was the material.

Three unexplainable, avant-garde figurines. The whole thing weighs about 120 kilograms. That's plenty of material.

"I think this is the work of <>, isn't it?"

Reinhardt says a strange name.

"Who is it?　Who is it?

"I don't think Jin would know."

Then Reinhardt explains simply that Tengkunhan is a craftsman who was popular for a while, but now he is tired of it and no one knows what he is up to.

"...... will be gratefully used."

After expressing his apologies to the author with his hands together, Jin easily fused and homogenized them into ingots.

"Brilliant as always," he said.

Now, the real work begins.

What Jin is going to make is a pump for deep wells.

The depth of the well here was about 10 meters.

Since ordinary pumping wells use atmospheric pressure, the theoretical depth of the well is about 10 meters (at 1 atm = 1013 hectopascal), but in reality, only 7 to 8 meters of water could be pumped up.

Therefore, several methods are considered for deep wells.

For this project, Jin adopted a submersible pump because of its ease of construction and maintenance.

"Reinhardt, you make the pipes. I'll adjust the final size, about 8 cm inside diameter. The length is 10 meters."

"Okay, here we go."

Jin made the same pump as the one he had made before, but with a more precise piston and cylinder.

The handle of the pump is quite long. He also made a very long stick.

"Reiko, Steward, help me set this up."

"Yes."

"Yes."

The pipes are long and heavy. Steward weighs more than 200 kilograms, so this is the perfect time for this.

"I'll explain it all later."

Jin said to Reinhardt and started to install the pump.

The biggest difference between this pump and an ordinary pump is the location of the pump itself.

In the case of deep wells, the pump itself is submerged underwater. This is called the submerged cylinder method.

In this way, the water is <> instead of <>, and can be pumped as far as meters, as long as there is enough power.

However, this can only be used with a dug well, not a well with a pipe driven into it.

"Okay, yes, yes. Hold me to that. ......<>"

The pipes are assembled. The piston of the pump is attached to the long stick, which is then attached to the handle.

"Father, I'll hold this one down.

With Reiko's help, the work is much easier. It was my first time to install a deep well pump, but I could finish it in about 15 minutes.

"Okay, the piston and cylinder are sliding well.

Jin nods in satisfaction as he moves the handle and looks around at the crowd of onlookers.

Some of the innkeepers who were not available and some of the guests who were staying at the inn had gathered there as if they were curious to see what the Magi Engineer from another country was doing.

Among them, Jin found the girl who had been working as a doorkeeper.

"Oh, there she is. Come here for a minute.

Jin beckoned her to come out, and she came out with a slightly worried look on her face.

"Yes, is that me? ......?"

Jin smiled reassuringly,

"Yes, it's you. Listen, try moving this handle up and down like this ......."

Lifting water from the depths requires a certain amount of force. Therefore, the handle of this pump was longer than the one in the village of Kaina.

"Yes, like this. ......?"

The girl slowly moves the handle up and down. 20, 30 times. The handle became heavier and heavier. Just then, water came out of the outlet.

"Ah!"

The girl is surprised. The gallery watching the show also gasps in amazement. >>The gallery watching the show also let out an exclamation of amazement.

"Good, you made it. You can fetch water a little easier from now on.

Jin then patted the girl on the head. Jin patted the girl on the head.
