The day after Elsa's birthday party, Jin officially received his award and inventory.

According to the inventory, he received a certificate of <>, an insignia, and a half-coat.

Since I had received the insignia the day before, I have the certificate and the half-coat today.

The standard attire for a noble mage is a robe, and for a knight a coat, but the Magi Craftsman of the Kingdom of Egelea wore a half-coat.

The coat of arms of the Kingdom of Egelea is displayed on the left breast and back.

The certificate is a mithril silver plate engraved with Jin's name and the words "guaranteed by the King of Egelea".

The insignia with an eladrite on it, which he received yesterday, is to be worn on the chest or lapel of his daily clothes.

And, although it is not a complimentary gift, Jin will be given a carriage and a horse for his exclusive use.

At this time, when I told him that I wanted to make it myself like a magecraftsman, he laughed and agreed, writing out the necessary materials and handing them over to me.

"Well, I guess I'll just have to give it a shot now," he said.

After yesterday's award ceremony, Jin had been threatened by Reinhardt that he would be in a lot of trouble, so he was going to build a defensive carriage, at least in case of unfriendly contact.

"Basically, the frame is made of light silver with adamantite coating on the sliding parts. It is pulled by a golem horse."

You can imagine what an extraordinary carriage this would be.

"The wheels are also light silver with adamantite ball bearings.

But there's just one problem. There is only one problem... there is not that much light silver in the castle's warehouse.

"Well, what should we do?

Jin has an idea. It is to install a warp gate in the carriage.

Originally, he had planned to install a warp gate to Horai Island somewhere, and he had brought the important parts with him.

If a small warp gate that one person can pass through is installed in the cabin or in the corner of the luggage space, he can return home anytime he wants.

And Jin is planning to bring materials from Horai Island.

So, the first step is to build a temporary cabin. Since this cabin will not be used after the completion of the original carriage, it should be made appropriately.

It is more difficult to set up a warp gate in it.

Reiko, who is small, took care of most of the work, and Jin only had to fuse and joint the materials.

The temporary cabin and the warp gate were completed in about an hour.

Reiko immediately jumped to Horai Island to send out the necessary materials.

"Well then, father, I'll be on my way.

With these words, Reiko jumped to Horai Island.

On that day, Reinhardt and Erza were invited by Reinhardt's friend, and Count Kuzma and Bina were invited by the Count's friend, and both Reinhardt and the Count wanted to take Jin out with them, but Jin stayed alone because he wanted to build a carriage.

Until the materials are gathered, Jin decides to study the details of the carriage.

"Hmmm, I should be a little cautious," he says auspiciously.

He is thinking auspiciously, "Hmmm, maybe we should weigh it a little," but he knows even now that the result will not be dead weight, but no one is here to point this out to him.

"Would it be a bad idea to have a 4-wheel independent suspension ....... Let's go with a trailing arm ......."

The front and rear trailing arms can take a large stroke, and the axle acts as a so-called torsion bar.

The axle is fixed and the wheels turn, so turning is easy.

"What should we do about the damper? It would be a bad idea to make an oil damper. I should use a material with viscoelasticity for the suspension spring.

Reiko came back to the room as I was putting together my ideas, muttering to myself.

"Father, I'm home!

"Oh, Reiko, just in time, I've just decided on a plan too.

"Well then, I'll start bringing in the materials."

Reiko then speaks into the manacam in her hand.

"This is Reiko, Topaz 2, send out the materials."

"Topaz 2, copy."

Topaz 2, who must be waiting behind the warp gate, replies, and after a few seconds,

"Here it comes."

A light silver ingot came out of the warp gate. Reiko takes it and places it next to Jin.

"Okay, next."

<, and Topaz2 follows the instruction and sends out the materials. In the blink of an eye, piles and piles of materials are piled up.

Jin, who was watching them, said

"All right, stop it for a while. If you run short again, ask for help."

"Yes, sir."

Reiko gave the order, and the shipment of materials was temporarily halted.

(It would be convenient if Reiko and the others had a built-in communication function, wouldn't it?)

(It would be convenient if Reiko and the others had a built-in communication function...) Jin headed for the pile of materials, thinking about it.

"Let's start with the cabin.

He decides to start with a space that can be used as a living room. The image he has in mind is a six-passenger one-box car.

The interior dimensions are 1.8 meters wide, 4 meters long, and 1.9 meters high. Even Reinhardt would not hit his head on it.

The frame is made entirely of light silver, and the walls and floor are both honeycombed and covered with wood to give the appearance of wood.

So far, no one has seen it. It was worth working in a lonely place behind the guest house.

"Well, now we can move the warp gate.

The warp gate is moved from the temporary cabin and installed. Reiko can pass through it as it is, but Jin has to bend down a little to get through. However, there is no problem in its function.

It is well disguised and hidden in such a way that it cannot be seen even if one looks closely.

The windows are not made of glass but of white mica and have window frames that can be opened and closed. Skylights were also installed on the roof for ventilation and to allow the driver to look outside.

Finally, the body of the car.

"First of all, the wheels.

The diameter of the wheels should be large enough to allow the vehicle to travel on rough roads, but if they are too large, they will affect the overall length of the vehicle (making it longer), so we decided on a wheel diameter of 60 cm.

The wheels are made of light silver and painted black.

"I think it would be better to have a larger stroke."

I thought about the length of the swing arm. Then, an idea came to him.

"Yes, yes.

I don't have to imitate the carriages of this world, nor do I have to recreate the suspension of modern Earth.

"Golem's arm ......"

That's the answer. Jin's golem arm has a skeleton and muscles. Muscles are springs and dampers.

In other words, when an external force is applied, it bends to release the force, and when the external force is removed, it stretches to quickly return to its original position.

"This is good!

So, using a reinforced light silver skeleton and magical fiber muscles, we ended up with a four-wheel independent suspension.

The outside is covered with a light silver cover, so that no one would be able to tell that the inside has such a structure.

In addition, Jin added a reclining function to the seats, including the coachman's seat.

He has also added brakes, something he forgot to do when he and Reinhard converted the carriage. It is a simple structure that uses a golem's hand and a palm-like part with brake pads to grip the wheel and stop it.

And a front light using the magic of <> and a ventilation system using the magic of <>.

Furthermore, it is equipped with an air conditioner that uses the magic of <> and <>.

Finally, we build a horse to drive it. In other words, a golem horse.

You may be thinking, "Of course we can't install a golem engine.

I can almost hear them from somewhere thinking, "We can't just install a golem engine, can we?

The golem horse has been built many times and completed in a short time. At that time,

"...... Thank God. We made it in time."

I heard her voice.

I looked and saw a gasping Elsa standing there.

"Jin, I wanted to see the first carriage you made.

Erza, who must have been running, gasping for breath and with sweat beading on her forehead, looked at the carriage with a twinkle in her eye.

"Is this Jin's carriage?"

"Erza, did you come running?"

"Yes."

Jin was a little surprised at the unusual sight of Elsa,

"Yes. Well, you can drink this."

Reiko, who had prepared the snacks for Jin, who was absorbed in the cooking, took the Citran juice from the set and offered it to Elsa,

"Thank you."

Elsa thanked him and drank the juice in one gulp.

"Fuu."

Returning the empty glass to Jin, Erza again said

"I want to ride in the carriage you built, Jin. I want to ride in it. Can't I?"

Jin couldn't refuse. He had not tried it yet, but there seemed to be no problem with it,

"Okay, we're going to try it out now, if you want.

With these words, Jin hurried to finish the last adjustment.
