 By the evening of the same day, the amphibious vehicle was completed as a gift.

"Wow, you did it, Jin! I only helped a little with the ......."

"No, Eira helped a lot too. Besides, if you were asked to build another one, you could, couldn't you?"

"Well, ......, if you're willing to put in the time," he said.

"Well, you can't say I just helped out a little bit.

 It is true that more than half of the work can be said to have been done by Jin, but Eira was definitely instrumental, and KaChea made a major contribution to the design.

 So did Jin,

"It's been a long time since we worked together as a , so it was a lot of fun.

 He is not afraid to say.

"Yeah, me too.

"Me too!"

 The three of us smiled at each other.

"......By the way, what did you say about Groma and ......, what happened to the <> teacher?"

 Jin asked after all these years.

 <>. Marikka used to be a lecturer at this laboratory, which is at the cutting edge of Golem research.

"It's a little late for that. ....... He's back in the country on vacation. Oh, only Groma isn't."

 He says he has no intention of returning to the Principality of Mercana.

"I'm accompanying the teacher to the Kingdom of Egelea."

"Oh, I see."

 It seems that he is trying to broaden his horizons. It was just like the earnest Groma Tollei, Jin thought.

"We're staying at home. But thanks to that, Jin and I were able to do such an interesting job.

"No, what?"

 Afterwards, Jin and his friends took a bath and promised to have dinner together.

 So Jin is soaking alone in the men's bath.

 The first bath was a salt spring with water from the sea. It warms your body.

 Next is a baking soda spring. It makes his skin smooth.

 Then Jin takes a bath in the simple spring.



 After Jin left, Eira and Ka-cea came to the lounge to drink cold juice.

"I'll have one too," said Eira.

"Me too."

 After spending such a long time together, Jin and his friends had dinner together in the dining room and went to bed early, promising to see each other the next day.

 The next day, of course, meant making a gift.

 <
"I was thinking about it last night before I went to bed, and I thought that since it was going to be a gift to the king, it would be nice to make a figurine instead of a tool.

 A crystal figurine," Jin said,

"Yes, indeed. A gilded ornament, that would please the powers that be.

 Eira agreed in a way that showed no respect.

"And..."

 Jin said, remembering Stearina, who had been a member of the in the past.

"Let's make a crystal golem."

"A crystal golem?

 Eira was astonished. Katya rolls her eyes, unsure of the level of technology involved.

"Well, it doesn't have to be crystal, it could be diamond or ruby..."

 Come to think of it, when is the new king's birthday? Jin muttered,

"September," Reiko told him.

 Reiko told him.

"I see, so it's sapphire.

 There is not much concept of birthstone in this world, but Jin wanted to be particular about it. Another reason is that sapphire is easy to synthesize.

"Alumina is available at ......."

 Alumina, or aluminum oxide, is used here in Avalon for various purposes, including crucibles, as a heat-resistant material.

What do you make of it, Jin?

"Sapphire is a crystal of corundum, or aluminum oxide."

 Reiko refused and brought a bag of alumina from the warehouse. These are powders, which can be sintered to make crucibles or heat-resistant materials.

"I should have about 200 kilograms."

 The specific gravity of aluminum oxide is approximately 4.0, which means that 200 kilograms would be needed to make a human model that weighs 50 kilograms.

"Gin? What on earth are you doing ......"

 Just as Eira is about to ask, Jin activates his engineering magic.

"<>"

"Wow!

 The powdered alumina crystallized and turned into transparent corundum. > is, as the name suggests, a magic to promote crystallization. Since it consumes a lot of mana, it is not an engineering magic that anyone can perform.

"Now, we need to add some color to it.

 Corundum is mixed with trace amounts of iron and titanium to give it that blue color.

"<><>>"

"Whoa?"

"Wow. ......"

 After the trace elements were added and uniformly dispersed, the material was crystallized again, resulting in a blue sapphire mass.

 Both Eira and Katya admire the beauty and Jin's skill.

"That's it! Reiko, take care of the mithril too.

"Yes, Father."

 The color is slightly muddied by the addition of mithril, but this is unavoidable, as it allows the magic to pass through more easily. And even if it is muddy, it is only a little and does not matter at all since it is not treated as a gem.

<><>"

 In the case of mithril, the trick is not to crystallize it.

"Now the material is complete."

"...... That's great, Jin. That's what I'm talking about.

"Really ......."

 The two marveled,

"Eira, use this to make a body for the golem. Katya, I want you to decide on the proportions."

"Okay, okay."

"Okay." "Yes."

 While Eira and Katya were preparing the body, Jin prepared the control core.

"Jin, how about this?"

 Eira and Katya were building a female adult body. She was about 160 centimeters tall, with glamorous curves. Her hair was designed in a short-cut style.

"Oh, she's beautiful. You're both so beautiful."

 Jin compliments them both.



"And the sensor?

"I have no idea about that one. Let's see what Jin can do.

"I see. I hope ......< will do some research on this. Well, you'll see."

"Yes, I will. I'll be glad to help."

 Eira declared and leaned forward to watch Jin's every move.

 Katya, with a notepad in her hand, was also watching closely.

"Here's what we're going to do."

 Jin began to add more processing.
