Reincarnation with AI (Unemployment-Free)

Chapter 77 Ultrapure Water

After receiving Philip's permission, Rudius toured the library in the following days.

Unfortunately, Rudeus did not find any magic book.

The library contains a large amount of financial documents, followed by history, etiquette, and storybooks.

These books did not teach Rudeus any new magic.

The magic books in the library are exactly the same as the magic textbook that Rudeus owns.

It is said that this book has been a bestseller with hundreds of copies since it was published about a thousand years ago.

And it began to circulate widely in the market fifty years ago.

Thanks to this magic textbook, which is cheap and available to anyone and anywhere, the number of magicians has exploded.

A trend of becoming a magician also emerged among the nobility, with many learning magic during their education.

But since printing didn't exist in this world, books were still very expensive.

While shopping, Rudius saw the book that Senes had given him when he was five years old in a high-class bookstore. It was priced at seven gold coins.

Based on Rudius's current salary, he would have to work for three years without eating or drinking.

For ordinary people, that is an insurmountable chasm.

If you calculate it that the magic textbooks can be mass-produced, someone must be subsidizing the distribution.

Rudius instinctively felt that the "sages" of the jobless world were exerting their influence, and that this behavior was clearly a form of popular education.

Who has such great love?

Rudius opened the magic textbook, turned to the copyright page, which read: Published by Lanoa Magic University.

Hmm... is this a conflict of interest?

Perhaps we shouldn't think of them as too noble.

Rudius then thought of another example: If you're selling sports equipment, like table tennis, then your best marketing strategy is actually to build more table tennis tables.

However, whether it's to popularize education or to expand the market base, these two are not contradictory. As long as it actually promotes social development, it's not a big problem to call out "the sages".

With a sigh, Rudius silently put down the textbook in his hand.

The purpose of exploring history is to uncover the treasures left by our ancestors.

But after some investigation, Rudius's long-held suspicions were confirmed.

The reason why magicians in this world are so weak is precisely because of the gap in knowledge, which deprives magicians of the fertile ground for growth.

As the head of a high-ranking noble family in the Kingdom of Asura, the only entities with a collection exceeding this library are probably the royal family and the Magic University.

Since nothing can be found here, it means that magic has not formed a complete knowledge system in the jobless world.

If even the libraries of high-ranking nobles don't have high-level magic books, then the problem isn't "not enough books," but "there simply aren't any."

Even if some high-level magic has been passed down, it will only be remnants of history, scattered here and there in the treasury of some royal family.

Rudeus put the spellbook back in its place and walked out of the library—it seemed that the idea of ​​digging out Euclid's Elements from the library and then stepping on the shoulders of giants to reach the top was just wishful thinking.

Back in his room, Rudius fell into a brief daze.

What to do next?

Rudius originally intended to learn some new knowledge, and of course he would take the shortcut if there was one.

To avoid spending half a year struggling to figure it out only to find that the book already has a detailed tutorial.

That would be incredibly stupid.

Since we haven't received any additional information, we don't need to think about it too much.

Rudeus intends to start all over again with the magic.

This kind of thing was actually done when I was teaching Sylphie.

From the very beginning, following the incantation, to later adding imagination, and finally becoming true magic without incantation.

What was I thinking back then?

Rudeus was lost in memories, seemingly a reaction to the flames of fire magic.

Because of the fireball's color change, he incorporated his imagination into the spellcasting process, thus unlocking true incantationless magic.

With a raised hand, Rudeus released a small fireball and began to continuously supply and compress magical energy, imagining the addition of metallic elements.

The fireball's temperature continued to rise, gradually changing from orange-red to blue-white.

Visible ripples began to appear in the air above the fireball.

The attempt ended in failure once again.

The fireball changed from red to blue-white simply due to a natural change caused by the increased temperature.

While the inclusion of imagination was correct, Rudeus had tried to recreate the flame reaction using fire magic more than once afterward, but all of them failed.

This aligns with Rudius's understanding.

According to Einstein's theory, matter and energy can be interconverted.

However, this transformation requires a huge amount of energy as a prerequisite.

Rudius felt that his failure was due to insufficient energy.

The problem is that water and soil are also generated by converting them using magic as an energy source.

Why is it so easy?

Rudius had no idea.

Make a water ball with your left hand and a stone with your right hand.

Rudius looked back and forth at the substance in his hand.

Gradually, Rudius recalled a question—doesn't water also contain ions?

Does this count as the formation of matter?

This issue was not investigated in depth at the time.

Rudius removed the stone from his right hand and made a new stone bowl.

Throw the water ball in, then heat it up with fire magic.

My hands were busy, and my mind was also working.

Rudius watched the rising steam and quickly realized the difference between the two.

The ions in water are hydrated ions, while the ions in flame tests are, simply put, chemical reactions caused by the addition of solids.

The ions in water magic are inherent to the release of magic, while the flame reaction has an additional step of generating a solid state—the experiment itself is essentially generating matter.

As the water in the stone bowl boiled away, Rudeus used magic to refill it.

After repeating the process several times, a layer of scale appeared in the stone bowl.

Rudius did not conduct this experiment last time.

Since it's a complete overhaul, it's normal to have more steps involved.

Rudius looked at the stone bowl—where did all this limescale come from?

In Rudeus's understanding, water generated by magic is transformed from magic power; it can be said to be generated out of thin air.

He reached this conclusion when Locci led Rudius to release the Cyclops Rain Cloud.

On the grassland under a clear blue sky, a violent storm is about to erupt.

The moisture in the air alone was clearly not enough; it had to be magically transformed into water vapor.

After Rudius could think of no other possibilities, he began to ask questions.

When magic generates water, it may not just be "creating" water molecules, but rather "transporting" or "simulating" water from the environment.

Moving?

Rudius pondered the principles, referring to the possibilities offered by the AI.

If it's about transport, does that mean water magic is essentially a type of teleportation magic?

It seems outrageous, but it's free to try.

Rudius created water spheres again, experiencing the process of casting spells, trying to catch some clues.

Got nothing.

Rudius dropped the water ball into the kettle and made another water ball, this time slowly increasing its volume.

Still nothing.

Rudius tossed it back into the water bottle, gathered his magic, and in one go created a water ball the size of a basketball.

Still nothing.

Rudeus could not sense any fundamental difference between the three spellcastings.

If it's teleportation, the casting process should feel noticeably different depending on the size and speed.

Standing up, Rudius opened the window and launched the water balloon in his hand into the flower bed not far away.

I made several larger water balloons and threw them into the flower bed, but still found nothing.

I closed the window, sat back down at the table, and looked at the suggestions the AI ​​had given me.

The experimental logic is not rigorous enough.

The water inside the water sphere should be tested to ensure it is identical to water in the environment (e.g., by labeling it with isotopes or mineral composition).

"As if I could do that. If I could separate isotopes, why don't I just make a nuclear bomb?" Rudius looked directly at another possibility: simulation.

What does this mean? What simulation? What are you simulating?

When magic generates matter, it refers to a "standard sample" in the caster's perception.

"Tsk," Rudius clicked his tongue.

Isn't this just imagination?

Rudius knew the concept of pure water, also known as ultrapure water.

Rudius realized the importance of ultrapure water during the previous derivation process, but after creating it, he put it aside.

Knowing the concept doesn't mean you have to imagine it when casting water magic.

Making ultrapure water wouldn't benefit Rudyus at all.

This water doesn't taste good; in fact, it's quite unpleasant.

Rudius did not put the ultrapure water on a fire to see if it would leave any scale.

Rudius took just one sip and was certain he had made ultrapure water.

The first sip often tastes bitter or sour, or has a dry, cotton-like sensation.

Many lab technicians who drank ultrapure water for the first time described it as "dead water," saying it not only failed to quench their thirst but actually made them thirstier.

Rudeus was already used to using magic to make water to drink; the taste of ultrapure water was significantly different from that of normal water.

The feeling of electrolytes being stripped from the surface of the tongue is unpleasant.

As for other uses...

Back then, when I asked AI what ultrapure water could be used for, the answers were all about applications like lithography machines, reagent preparation, and nuclear power plants.

Once this was put aside, Rudius forgot about it.

While researching the magic of laundry, Rudeus did recall that ultrapure water did not offer any significant advantage in washing clothes.

So it was put on hold again.

At that time, Rudius had not yet made the connection between the two ions; he simply felt that since he could make ultrapure water, he should be able to make a flame test.

It now appears that the so-called flame test is stuck on the path of producing the substance itself.

We still need to do the experiments ourselves.

Rudius made a new stone bowl, added ultrapure water to it, and started boiling the water.

As for directly creating matter, or rather, metallic elements, using magic.

Rudius had no clue about this matter either.

Metals are far more complex than water.

Rudius doesn't actually need to think about oxygen and hydrogen atoms; he only needs to think about water to make ultrapure water.

But the sword in the swordsman's hand must be made of an alloy of various substances, and Rudeus could not imagine what that was.

In a different world, is iron still iron?

Is water really made up of oxygen and hydrogen?

Without conducting experiments, Rudius dared not draw any conclusions.

Based on the boundaries of cognition, oxygen, hydrogen, and water are clearly three different things.

There is no periodic table in the world without jobs.

Given our current level of knowledge—we haven't even discovered cells yet—the discovery of atoms seems even more distant.

Rudeus remembered that in the original Seven Stars section, it was mentioned that everything in this world contained magic.

In a world without job titles, magic is probably as inseparable from time and space as spacetime.

The more Rudius thought about it, the more complicated things became. Although he was very interested, he decided to put it aside for now.

I'll study it more carefully when I have more free time later.

Let's turn our thoughts back to ultrapure water.

Rudius recalled that the AI ​​mentioned that this thing could be sold for money.

Perhaps alchemists would be interested in this kind of water that produces no impurities no matter how it's boiled.

Rudius, who was still in the village of Buena at that time, kept this in mind.

Dirty adults are always thinking about how to make money.

Rudius added ultrapure water several more times, and then boiled it dry.

Sure enough, no limescale was left in the stone bowl.

Hmm—the tongue's judgment is correct.

I'll ask Philip for a favor another day.

As for other characteristics of ultrapure water, such as boiling over and supercooling, these are all caused by the fact that it is too pure and there are no substances in the water that can act as condensation nuclei.

It is an application of phase change processes, which are also related to water.

Ultrapure water can be heated to temperatures far above its boiling point without boiling.

Rudius remembered that in his previous life, there was a rule in the laboratory that ultrapure water could not be heated to avoid burns.

This could be a clever little trick: offer someone a glass of superheated ultrapure water that looks like cold water.

However, this little trick is far inferior to the one used to sprinkle medicine powder.

It lacks both practicality and destructive power after completion.

Rudius put the little idea that had just come to mind out of his mind.

Trying to scald someone to death with ultrapure water is less reliable than trying to cause water intoxication with ultrapure water.

For Rudius, when discussing the physical properties of ultrapure water, the most crucial aspect is insulation.

As is well known, ultrapure water is non-conductive.

With the Great Transfer event drawing ever closer, it's time for Rudius's final sprint, according to his plan.

Rudyus needs a decisive move.

Therefore, ever since he learned magic, Rudeus has been relentlessly practicing magic compression.

The so-called killing move is naturally the Water King-level magic [Lightning].

The power of lightning is terrifying, and it is also unavoidable.

For Rudeus, who was eager for power, this kind of magic that could be used immediately was the best.

However, Lightning Strike is a higher-level spell than Thundercloud, and according to the procedure, Thundercloud should be released first.

Rudeus would not release a water-level spell before engaging an enemy.

If one has the leisure and inclination, there's no need to develop any magic at all.

With his ability to fly, Rudeus is now invincible.

Lightning can obviously be controlled, and given the casting range, there's no need to worry about being struck by lightning.

Rudius's main concern was close-quarters combat with the warriors.

To use it in this situation, lightning needs to be developed into magic that can directly unleash lightning.

The purpose of ultrapure water is to prevent electrocution during this process.

Before going to the library, Rudeus would also have the delusion that he could find gravity magic.

Taking shortcuts has always been Rudius's top priority.

For now, let's proceed according to the original plan.

As the sun set, the room gradually grew dark.

The boy sat quietly in the room, a tiny light shimmering in his hand.
