Chapter 2008: 2008 - - 54-07 Lecture No. 4

After Freddy talked about magil resin, it was Greiner's turn to speak. She talks about biological materials, especially threads of ground spiders.

In recent years, the cultivation of "ground spiders" has become popular, and the threads from these spiders are used in various fields.

True to his word, there are at least three farms in each country producing <> and <>.

"I think many of them are using abandoned mines as aquaculture farms. ...... I would like to go a little off topic here, but I would like to say a few helpful things about this aquaculture."

Everyone listened attentively to what Greiner had to say.

"The ground spiders live on free magical element (ether), so it is not necessary to take care of them, but it is a good idea to make some adjustments to the environment in which you keep them.

The subterranean spider's vision is actually ultraviolet and infrared rays. Visible light is completely invisible to humans.

Infrared rays in dark places and ultraviolet rays in bright places. The ultraviolet rays are the tricky ones.

"Threads spit in the presence of ultraviolet rays are weak.

On Horai Island, the threads are cultivated in an environment where there is almost no light, tens to hundreds of meters below the ground, so the strength of the threads is much stronger than those from other regions.

Of course, this is not the whole story, but this is the result of my research on why the threads of ground spiders cultivated elsewhere are not as strong as those of other spiders.

It is speculated that freshly expelled threads are less resistant to ultraviolet rays, but it is not known whether this is true or not. Verification is still awaited.

"The reason for this is still not well understood. I would like to avoid discussing it here. ......Now, the threads collected from this subterranean spider (grand spider) react to magic as well, so ......"

The main topic, the material of <>, was discussed.

"Before the ground spider, we used the threads of insects. (a kind of insectoid) and (a moth-like creature). However, since the supply was not stable, they were replaced by ground spiders, which can be cultivated.

This explanation is a bit roundabout, but this is due to the fact that Jin told me that most of the students do not know the background and blindly choose the materials.

It is not surprising that they do not know. Such lectures are rarely given.

This is because the materials on such matters have been lost due to the <>.

"......Therefore, the threads of the ground spider (grand spider) still have potential applications. It is the role and privilege of our generation to find it. Let's keep up the good work!"

With this, Greiner's part in the discussion was over. The auditorium erupted in applause.

Then it was Rubina's turn.

Somehow, Jin thought, he could feel the audience's confusion ....... (Well, that's understandable, isn't it?

(Well, it is understandable...).

(Well, understandably so, since all the people who had gathered to listen to the lecture were older than Rubina.

My name is Rubina. My talk is about <>.

Rubina began to speak more clearly than Jin had expected. She must be the type of person who is good at the real thing.

"Some of you may be wondering about my age. But please put that aside for the moment and listen to what I have to say.

Jin was impressed with the introduction. He must have been thinking about it for a long time. ......

"What did you think of when you heard about rare materials?　Adamantite?　Dragonite?　Or eladolite?　They are all rare."

The audience seemed to be listening attentively, impressed by the way Rubina spoke.

"Rare materials have wonderful properties of their own. Adamantite is the hardest and strongest metal in the world, and dragon materials are highly durable. Eladolite has amplification properties not found in other magi crystals.

Here Rubina's description returns to the new golem.

"The golem that the three of us created under the guidance of Professor Jin does not use any special materials. We discussed the possibility of using them, but that would have defeated the purpose of mass production and industrialization, so we used common materials.

But," says Rubina.

"We all agreed that we didn't want to compromise the performance of the product. So, we devised a solution. We are proud to say that we were able to achieve a performance ...... that is not quite on par with rare materials, but close to it."

Water on the board. Rubina speaks without hesitation. The audience had already forgotten that she was 10 years old.

"The first one. . I think that we want to make the case that protects an important magical device as strong as possible.

In fact, we would also like it to have a shielding effect to prevent <>.

"We have considered the forces that would be applied to this case. We have concluded that more than 90% of the force will be from the outside to the inside.

That's true. It is too unlikely that an outward force would be generated from the inside.

"So we examined the structure and devised a honeycomb structure made of stainless steel to increase the strength. This structure is described in Appendix 2 at the end of this document.

The sound of a bee flipping through the document echoed through the room.

The honeycomb, or honeycomb-like hexagonal structure was used.

Honeycomb" means "honeycomb," or honeycomb" is an English word meaning a comb of bees.

Why it is called a comb, Jin does not know. <, .

Regardless, this structure is especially strong against forces perpendicular to the hexagonal surfaces. It can also be light.

In other words, it is able to gain strength against forces from certain directions while keeping the weight low.

Then, if you build the same structure with adamantite, there is no ....... Certainly it would be stronger, but there is no end to it.

Jin was a little worried that Rubina would explain all the innovations to the assembled engineers,

"I think it would be rude to all of you who are here if I tell you everything," she said. Please come up with some ideas that are better than ours, and let us work together to develop the technology. And let's work together for the development of technology.

He concluded by saying.

"Well then, thank you very much for listening to this young man's talk."

Rubina bowed and withdrew.

Her bow was in stark contrast to her mature tone, and she burst into laughter, which was followed by thunderous applause.

"Oh, oh, ......, I can't take it anymore. I'm at my limit."

Rubina retreated to her dressing room and slumped back in her chair.

"That was good, Rubina."

Jin praised her.

"You'll be out of action now, so get some rest."

"Yes, ......."

"Thank you very much for your hard work, Gulina and Freddy."

"...... tired, but I learned a lot."

Me too."

But Hitoshi, who couldn't bear to see them like that, said,

"Hope, Reiko. Serve them Persian juice."

"Serve them Persian juice," he instructed.

"Yes, sir."

"Yes, Father."

Reiko, who had not been present at the lecture, was particularly enthusiastic and took a thermos filled with Persica juice from her luggage. Hope prepared a glass.

Persica juice from Horai Island is full of nutrients and relieves fatigue.

"Oh, it's delicious!"

All three of them are taking a break after drinking the juice.

"Ha-ha, that must have been a good experience.

Speaking in public takes more mental strength than one can imagine.

When Jin was a newcomer, he too felt sick to his stomach when he was asked to give an explanation at a client's site. Well, you get used to it and you don't feel it anymore. .......

"Jin-sama, may I start the last lecture with you?

Marikka asked. She seemed to want Jin to give the last lecture.

"Yes, we agreed on that in the meeting, didn't we?　Marikka is the senior here and her name is well known.

"Oh, I see."

* * * * * *

<>. Professor Jin, Marikka-sama, thank you very much for your cooperation.

At this point, Jin took the podium first, as had been arranged.

"Today, I have given my poor opinion at length, but it seems that it is time for me to summarize it.

>I can hear you saying, "I didn't feel it was that long, did I? Jin thought again that the Japanese way of speaking did not seem to be well understood.

"I am ...... a Magecraft Meister, and my philosophy is to make things that benefit people, even those who can't use magic.

This time everyone listens in silence.

"We have no intention of forcing you to do so. I am not trying to force you to do it, but even a little bit is good enough. Remember, it is not only for your own sake, but for the sake of many others. That's all for me.

Jin bowed and received thunderous applause.

Maricka took the podium in his place.

She said, "I believe that all of you here are ambitious people. Please keep that ambition alive. You will fail at times. You may experience setbacks. But that is the path that everyone goes through, big or small. Even I, ...... my mentor and my predecessor, , have had to go through it. What matters is what you do afterwards. Let your failures and setbacks be your food for thought. Use your ambition as a driving force, your intellect as a rudder. And let your heart of love be your compass. That's all I have to say.

Maricka also received thunderous applause.

The applause did not cease for a full ten minutes.

Finally, it was time for the Q&A session.

Jin was a little excited to see what kind of questions would come from the audience.
