Jin followed the amidakuji lottery to determine the competition events.

"......Ko de, ko,ko,ko ......To."

"a,a,a,a......"

Just when you think you are about to reach your desired event, it takes a sharp turn.

And then...

"A boat!　I did it!"

Natalia shouted with delight.

"Yes, I think we've got it!"

Maricka closes the event.

"This time it's a boat competition.

She added that she was glad to have a ship for the first competition, since there was no course for a golem car competition and the airship competition would require safety precautions such as crashing.

He added that it would have been better to use a ship for the first competition because ship competitions have been held in many places including Potrock, and know-how on the operation and safety of the competitions has been accumulated.

"I see, there are no car races.

Jin said a little disappointed. Then he added,

"There are circuits, which are a combination of curves and straight lines, and there are also those that are held on public roads or off-road," he added.

Maricka heard this and said, "I'm not sure if you can do it on a track or off-road. Maricka heard this and asked, "A circuit?

"A circuit? Sounds interesting. Shall we build it for the future?

She is very enthusiastic about the idea.

If we perform well in all the competitions, we can become the King of Magecraft or the Queen of Magecraft.

"......A pity it's not a giant golem competition at first. ......"

Rubina is a little disappointed, but Jin is not,

"If you want to be a queen, you have to be able to make anything.

Rubina was a little pouty. Rubina was then suddenly in high spirits.

"Yes, you're right!　I'll do my best!"

She jumped down from her chair,

"Let's get to work!

and ran to her workshop.

It seems that she has her own workshop in this institute.

"Master Jin, I am sorry for my noisy grandson.

Rubina's grandmother Amanda apologized,

"No, don't worry about it. A child should be as energetic as that.

Jin gently stopped her from apologizing.

"But before that, we haven't even decided on the rules and regulations yet.

That is more problematic.

I'll let you know when it's decided.

So, Jin and Marikka took the lead in deciding the details of the competition.

"Shall the boat be less than 10 meters in length and less than ......8 meters in width?

"Yes. ...... One pilot, can be a human, golem, or automata. The assistant can be a golem or an automaton, any number of them.

The number of assistants can be any number of golems or automata.

"The power can be freely ...... or with some restrictions?"

< was brought into the race, it would no longer be a boat race.

"Should we limit it to screws?　Or only jet propulsion systems (jet thrusters) ......"

Too many restrictions would reduce the fun by half, so it is difficult to decide how much to limit the use of jet thrusters.

"Let's limit it to jet propulsion (jet thruster) systems."

Marikka said that since the Golem can carry any number of people, the propulsion system should be such that it cannot be used to power the Golem.

She said, "Let's make it so that the golem can't row for propulsion.

"That's a good idea. Yeah, let's do that."

"Besides, as a boat, it should be in contact with the water except when it's bouncing.

We also decide on the rules.

"We can use any material we want. ......"

At any rate, I wrote down on paper what had been decided.

"Yes, I think this is good.

Jin thought that it might be interesting even if there were some omissions.

Jin was very interested in seeing the unconventional ideas that could be developed by taking advantage of such omissions.

"And then, when is the event scheduled to be held?

"About a week from now, I guess.

When Trihart suggested this, Jin wondered if it was a little too short.　Jin thinks that it is a little short, but if he thinks about it in terms of his own schedule, it is more than enough.

"Guys, two days should be enough time for production, but with time for adjustments and improvements, we're talking about a week."

"Yes, that would be fine."

Jin nodded his head, and thus the <> was held.

* * * *

"...... I want to make one too.

After announcing the competition to all of Onogoro Island, I had some free time.

"You can't go out, Gin-sama!"

Marikka said to me,

"Oh, no, it's not that. <

Jin explains.

"Oh, so that's what you mean. An example of production, something like that.

"That's what I mean."

"Then feel free to use the materials in this laboratory. We also have a few more workshops with docks by the beach, so feel free to use those as well.

Okay. Thank you.

Thus, Jin also decided to build a boat.

His assistant was, of course, Reiko. But..,

"Let me observe."

Marikka, Alvin, Edith, Stephanie and others came to the boat.

Jin has just started to build the hull.

The trimaran he is building is designed for stability.

It is disadvantageous in the sense that it will increase the viscous resistance of the water, but we are planning to reduce that resistance by adding water repellency through <>.

"A trimaran?"

Alvin seems to know the format.

The framework is 64 light silver.

Reiko, hold this side.

Yes, sir.

It is the same type as the still in operation on Horai Island, but in a more sophisticated form.

"I like the 64 light silver exterior plate."

Jin is assembling the machine by using <> and <>,<> and so on.

The speed of his work had everyone watching in awe.

"Wow, that's fast. ......"

"That's just what Jin-sama would expect."

"This is the power of your ancestor ...... Jin-sama ......."

After finishing the hull in about an hour, Jin checked the overall distortion and made slight corrections, and then started to build the propulsor.

"I'll use 64 light silver for this one too."

The advantage of using the same material for all the parts is that the distortion caused by the difference in thermal expansion coefficient does not need to be taken into account.

But usually we don't go this far.

"The main engine has three <>. There are four side thrusters for changing direction and one for retreating.

Jin continued his work quickly.
