Reincarnation with AI (Unemployment-Free)

Rudius retrieved the diaper from the washing tub.

He frowned slightly.

The washing machine performed far worse than expected.

Honestly, clothes from the jobless world can't withstand the test of an upright washing machine!

This is not to say that the current methods are not feasible.

Rather, it's inefficient.

Rudius had to spend a lot of time "quietly" stirring the water to wash the clothes.

Otherwise it will cause damage.

Even at this stage, compared to carrying it to the riverbank and beating it with a stick, it's already a qualitative leap.

But Rudius, who knew the efficiency of modern laundry, still felt that the efficiency was too low.

Damage is due to a problem with the strength of the clothing.

Rudius knew nothing about the textile industry.

He just instinctively thought that washing clothes this way was okay, so he went to try it.

But the deformed and torn diaper in his hand seemed to be saying, "No."

From the stories of the rich he had heard in his previous life, Rudeus probably knew that clothes made of animal skin could not be washed with water and needed to be dry-cleaned.

But why are these cotton and linen-like diapers so "delicate"?

Rudius understood after a moment's thought.

This can be compared to the food on the dinner table.

The little things in life will make you understand.

Just how much effort did your charming ancestors put in to live a good life?

It's just that people tend to regard things that existed before they were born as always.

The earliest rice was no different from the weeds and seeds that could be found everywhere on the ground.

It has low yield, falls off easily, is difficult to harvest, and has a rough and hard texture, making it impossible to use as a staple food to feed humans.

It is just one of many weeds.

Humans have transformed wild rice into the cultivated rice we know today through thousands or even tens of thousands of years of selective breeding.

Breeding, hybridization, genetic improvement, and processing.

This has turned natural creations into highly standardized industrial products displayed on tables.

To enjoy fragrant rice, all you need to do is rinse it and use a rice cooker with one-button operation.

What about the clothes?

What is it that allows these natural creations to withstand the frantic pulling of the water?

Why buy cotton clothes for twenty or thirty yuan?

You can put it in the washing machine, use hot water, and use laundry detergent. It won't shrink or fade after you take it out.

Whether it's the rice in our mouths or the clothes on our bodies, they are all the result of humankind's countless generations of intervention, modification, and standardization, which have completely reshaped the original natural objects.

It can be said that in modern society, most of the natural attributes of these things have been stripped away, and humans have inscribed artificially designed attributes into their DNA.

Rudius had little interest in the textile industry, but with agriculture as a comparison, he immediately understood the key point.

In fact, many protagonists in time-travel novels will search for the delicacies of their previous life after they travel through time.

Even the male protagonist of the original work, who had no job, was no exception.

Rudius actually wanted to do that too. He was also very interested in agriculture and longed to eat the food from his previous life.

However, for agriculture, a science grounded in reality, the most crucial limiting factor is time.

This constraint is a rigid, fundamental physical law that cannot be completely bypassed through technological means.

You must wait for the crop to mature before you can begin the next stage.

Photosynthesis takes time, cell division takes time, and starch accumulation takes time.

Spring planting, summer weeding, autumn harvesting, and winter storage—this is an ironclad rule.

This is seriously inconsistent with the input-output ratio that Rudius values ​​most.

If there were no threat from the gods, Rudeus would probably be quite happy to go with Senis to the garden to tend to the seedlings.

Who knows, his fifth birthday present might turn into a little hoe belonging to Rudius...

Now that he knew the reason, Rudius could only start with the washing itself.

We need to find a more efficient way to do laundry.

Rudius used his existing abilities to find several feasible solutions.

[Air wash/steam wash (high-end household washing machine)]

Industrial vacuum cleaning machine

Ultrasonic cleaning (utilizing the cavitation effect in liquids)

The first two are easy to understand; Rudius can do both steam and pressure adjustment.

However, in Rudius's mind, the most powerful cleaning agent is undoubtedly ultrasonic cleaning.

Rudius vividly remembered the scene from his past life where he put his eyes into an ultrasonic cleaning tank.

It wasn't just clean; the efficiency was truly astounding.

Logically speaking, humans cannot emit ultrasonic waves.

Even if ultrasound is classified as sound magic, it is ultimately categorized as wind magic.

Rudius also believed that such a vibration frequency was impossible to achieve.

In the past, ultrasound was formed by passing a high-frequency alternating electric field through piezoelectric ceramics.

This is similar to flying; the human body is not designed with this function.

But AI has provided a feasible solution.

If you are skilled with water and wind, you can utilize the "whistle" principle from fluid mechanics.

[Principle: In the real world, a dog whistle emits ultrasonic waves by blowing air. The key is that the airflow creates vortices and resonance when passing through a specially designed cavity.]

The key is to make a dog whistle.

Coincidentally, besides water and wind, Rudeus is most skilled in earth magic.

With continuous training, it is now possible to create a pot with the strength of metal using earth magic.

This is different from water magic.

In the rainbow experiment, Rudius was unable to stabilize water into a prism, which was due to the physical properties of water.

Soil, or rather, solid matter.

If you can't squeeze it anymore, you can just let go; it won't fall apart or deform.

You must continuously and steadily output magic to maintain the liquid's form.

The process was like practicing calligraphy or performing surgery.

The output of magic is like a hand; it must be applied continuously and kept stable.

Otherwise, even the slightest vibration would cause ripples in the triangular mirror.

Of course, it's not that you can't use it if you really want to.

Let's assume that Rudius can perfectly control the water-based triangular mirror, ensuring that its cross-section always maintains the shape of an equilateral triangle, only with some ripples on the water surface.

Even so... to make a comparison, if you had a perfect water sphere now, would you still use that constantly shaking prism?

It's like you can watch 4K videos directly. No, a perfect water sphere could easily be described as 16K, and it's 16K effortlessly.

Even if an unstable prism has a resolution of 360p, let's say it does.

At this point, would you choose to watch the 360p video that you went through so much trouble to get, or the effortless ultra-high-definition 16k video?

Solids are different.

Without external interference, a stone will always remain a stone.

Therefore, when using earth magic to create items, whether it's increasing or decreasing, strengthening or weakening, it's simply a matter of adding more water to more flour.

This means that even if Rudius knew nothing about dog whistles, he could still produce ultrasound by constantly adjusting the AI's text prompts and using the resulting physical phenomenon as a reference.

I just don't know how long this process of trial and error will take...

Rudius turned his attention back to the steam washing.

steam.

This was the first magic developed by Rudeus.

Since encountering a bottleneck in combat applications, it has shone brightly in other areas.

Cooking, experimentation, and now housework.

At a glance, Rudius knew that steam was useful.

When developing combat applications, Rudeus identified the property that steam could penetrate clothing fibers.

However, the most suitable application scenario for this feature is not combat, but washing clothes.

Clothing that deodorizes, removes wrinkles, and kills bacteria.

Oh my goodness!

Steam Lord's Divine Power!

It surprisingly combines practicality, safety, and aesthetics.

What should we do then?

Instead of using water, can we use a pneumatic washing machine?

Is there a possibility of using pneumatic force to beat clothes?

[To toss a thick, water-soaked cotton coat high into the air like it's in a tumbler and then drop it back down, the required airflow speed would be supersonic, which is neither safe nor energy-efficient in real-world use.]

Energy consumption and noise levels... poor washing performance...

Rudius frowned as he leaned over the washing tub, looking at the AI's description.

Seeing the noise reminded me of the terrifying howling sounds I heard in a factory in my past life.

Just thinking about it makes me uncomfortable.

Is this not allowed either?

Does this mean we absolutely have to design a front-loading washing machine?

Mechanical transmission is also a blind spot for me...

"Rudy?"

Hilfi's voice came from outside the courtyard.

Rudius clung to the edge of the washing tub, poking his head out and looking towards the doorway.

"Silphie".

"Rudy, you haven't been to the secret base for the past few days." Upon receiving Rudy's response, Sylphie walked towards him. "What are you doing?"

"Ah, well, I'm researching magic for washing clothes at home..." Rudeus scratched his head.

Since there were no cell phones in the Middle Ages, Rudius had no way to leave a message to notify Sylphie.

These past few days, Rudius has been so preoccupied with the family crisis that he hasn't had a chance to visit the secret base or Sylphie's house.

"Washing clothes?" Sylphie looked at the diapers in Rudeus's hand, then at the large bucket beside him. "Rude, you're really something."

"No, no." Rudeus said, showing the diaper in his hand to Sylphie. "Look, it's all torn here."

"Yes." Hilfi looked closely. "Could it be that you washed too vigorously, Rudy?"

"That's how it is, but if you don't use a little force, it will wash very slowly and waste a lot of time."

"Rudy, how did you wash it? Can I see?" Hilfi asked curiously.

"Sure," Rudius replied.

Rudius casually tossed the diaper on the ground, shook off the excess mud, and then threw the soiled diaper back into the washing tub.

The two of them lay together on the washing tub, watching the water churning inside.

"Is it clean now?" Hilfi tilted her head and looked at Rudeus.

"Yes, just keep turning it clockwise a few times, then counterclockwise a few times, and keep repeating that," Rudius replied, controlling the flow of water.

After a short wash, the diaper was clean again.

After all, it's just washing a diaper, and mud isn't that hard to wash off...

However, the diapers that were already in bad shape seem to be completely unusable now.

It looks just as dangerous as translucent toilet paper.

If you use it to wipe your bottom, it will only remind you of one word: "penetrating the paper".

"So, Rudy, are you looking for a way to wash clothes quickly without damaging them?" Hilfi asked.

"Yeah, I was just thinking about using steam to wash clothes."

Can steam be used to wash clothes?

"Of course, nobles..." Rudiusca hesitated.

Did medieval nobles use steam irons to iron their clothes?

do not know!

"Hmm?" Hilfi asked in confusion.

"Ahem, that's how it is, Silphie." With that, Rudeus pulled Silphie over.

He lifted up Silphie's coat and held it suspended in one hand.

Steam began to appear in Rudius's hands, and after it appeared, it passed through Sylphie's coat and floated upwards.

That piece of clothing underwent a deep "sauna".

Feeling that it was about time, Rudeus stopped the magic, and the steam dissipated.

"Do you feel the wrinkles have disappeared?" Rudius asked, pointing to the clothes.

"It seems so?"

Well, there aren't many wrinkles after all, and such a small patch won't make a visual impact. If the entire garment were ironed, the visual effect would be much more noticeable...

Rudius tilted his head. "Then feel it. Isn't it soft?"

"Hmm...it's very soft, but is it done washing already?"

"Silphie, I'm stuck right here." Rudeus leaned over the laundry tub again.

Pointing to the dirty water in the bucket, Rudius continued, "Hilfi, you see, if you wash it with water, the dirty stuff will go into the water."

Rudeus withdrew his hand and cast a steam spell. "Steam only makes clothes easier to wash; it doesn't actually remove any dirt."

"Huh? Then why not use both methods together?" Hilfi asked疑惑地, "Can't we just use steam first and then wash with water?"

"That's right, that makes sense!" Rudius, who had been lying on the barrel, sat up and looked at Silphi, saying, "Silphi, you're a genius!"

"No way... Rudy, you could probably guess that too," Hilfi said shyly with a smile.

"Yeah, how come I didn't think of that? What was I thinking about just now?" Rudeus scratched his head.

"Oh well, let's just do it the way of steaming first, then cleaning," Rudeus said, then invited Silphie, "Silphie, want to come along?"

"Okay," Hilfi replied happily.

Seeing that Sylphie had agreed, Rudeus naturally took her hand and walked towards home.

The diapers we have are already overloaded, and we need new clothes to continue.

Remembering the less-than-ideal ironing results, Rudeus decided to demonstrate for Sylphie.

As they walked, Rudeus said to Sylphie, "Let me tell you, Sylphie's steam is really amazing for ironing clothes."

"Really?"

"That's right, we'll go find a bigger dress, and you'll see."

Rudeus led Sylphie through the door, and Senis, noticing them, greeted them, "Oh, it's Sylphie. Are you here to play with Rudeus?"

"Yes," Hilfi nodded.

At the same time, Hilfi looked with a puzzled expression at Paul, who was standing not too far away, as still as a virgin.

Paul waved to Hilfi, as if to say hello...

This quiet feeling reminds me a lot of Lilia?

Slightly puzzled, Sylphie was pulled into the room by Rudeus.

"Rudy, isn't Uncle Paul acting a little strange?"

"Not surprising at all..." Rudeus said helplessly.

"This is how people of low status should behave..." Rudeus added helplessly to himself.

How should I explain this to Sylphie...? I'll just tell the truth.
