Craftsman: I continue to learn for the sake of the saints

Chapter 165

Seeing Qin Luo's innocent drunken appearance, Sister Cha couldn't help showing a smile on her face. After thinking about it, she pulled out her hair and gently scratched Qin Luo's nose.

Sudden itching, Qin Luo sneezed, but also opened his eyes, staring at her in a daze.

"Go to bed..."

"Go take a shower..."

Qin Luo pursed her lips and smiled, but she was a little sober. She nodded, and after washing up, she lay down on the bed.

Really sleepy.

On weekdays, I wouldn't be so sleepy like this.

Today, one is because of drinking.

Secondly, it is also emotional ups and downs, which are too strong.

Emotions, anger, sorrow, and joy consume a lot of mental energy.

"It seems that you are really happy. I haven't seen you so happy for a long time."

Sister Cha lay flat on her side, looking at the ceiling, whispering softly.

"How come? Don't you feel happy every day?"

Qin Luo retorted with a smile.

Sister Cha: "That's calm, not happiness. Happiness is when you smile to show your back molars."

Qin Luo couldn't help but turned over and looked at her.

So she turned around too.

Under the dim light, the four eyes met.

"Can you tell me about your past? It seems that you have never heard of it."

Sister Cha said in a leisurely voice.

Ever since he met Qin Luo, he has been like this, gentle and calm, mature and decent, almost never losing his composure.

Like a dummy, he has cultivated to a level of calmness.

Of course this is not a bad thing.

It can even be said that he is quite a superb man.

However, women are always greedy and feel that there is something missing.

"There's nothing to say, an ordinary person, going to school, working, living, going step by step."

"I had two friends."

"One is Zhang Ziqi, and the other, let alone talk about it, has passed away."

Qin Luo said softly.

Tea Sister: ...

Well.

It was silent for a while.

She felt that the atmosphere was a bit heavy, and wanted to relax, so she asked with a smile: "Do you have any female friends? Have you ever had a crush? Have you ever been in love? Have you ever been together?"

Qin Luo: ...

Laugh twice.

"No, I won't say anything. In order not to be used as a weapon against me in future quarrels."

Hearing this, Sister Cha couldn't help laughing briskly: "Six, it's so terrible."

"That's necessary, this is called prejudgment."

Qin Luo said proudly.

at this time.

Qin Luo's cell phone suddenly turned on, causing a slight vibration.

He took it out and took a look.

Under the dim light, the WeChat messages on the screen of the mobile phone are very clear.

"Are you asleep? Brother Luo?"

It was Fang Yichen's message.

It was already past one o'clock in the morning. Qin Luo frowned slightly when he sent such a message at this time.

I don't really want to reply right now.

I don't know what she was talking about with me.

Moreover, Sister Cha was still watching, feeling weird.

Although he has a clear conscience, but the melon field Li Xia.

The second message was sent again.

"Brother Luo, that Li Minghao, Mr. Li, has been teasing me for the past two days, which makes me a little... at a loss."

"Do you know him well? What kind of person is he?"

"I feel that the character is not bad, and the career is quite successful, but it is somewhat greasy."

Fang Yichen said this to Qin Luo as if he was complaining to his "best friend".

Qin Luo: ...

This……

It seems to be a very advanced way of chatting topics.

Qin Luo also had a preliminary judgment in Li Minghao's mind. He was definitely a veteran of flowers, and he was very purposeful, and he never did useless work.

It can be seen from the style of his organization.

The reason why the later Hanshan Temple Bureau was formed was probably because there was no plan to pick up girls through fan gatherings.

However, this kind of thing, I still can't explain it in detail.

We are all adults, one is willing to fight and the other is willing to suffer, what room do I have to interfere?

"I don't know, you can see for yourself."

"Talk if you like it, block it if you don't like it, how can there be so many entanglements?"

Qin Luo typed the reply casually.

Fang Yichen quickly replied: "Haha, okay, let me take a look again. I think it seems to be really good, but I am a little worried, afraid of being scumbags."

Qin Luo: "Make up your own mind, I'm asleep, bye."

"Okay, good night, Teacher Qin."

End the chat.

Qin Luo casually turned off the screen of his phone.

When we were chatting just now, Sister Cha watched the whole process, but now she licked her lips and looked at him with a half-smile.

"Good night, Teacher Qin."

She said in a slightly sweet tone, coquettishly.

Qin Luo gave her a blank look, but couldn't help laughing out loud.

"sleep?"

"Hmm. After chatting with other women, sleep with me?"

Sister Cha gently raised Qin Luo's chin with one finger, and said deliberately finding fault.

Qin Luo couldn't laugh or cry.

But also understand what she means.

- Paying taxes according to law is the basic obligation of every citizen.

……

Next room.

Yang Zi is still staying up late playing mobile phones, listening to music, and relaxing moments at night.

Suddenly, I heard strange noises from the next door. The sound insulation effect of this hotel room is really a bit poor.

She was stunned for a moment, and then suddenly came back to her senses, and immediately jumped up from the bed with a little excitement, and put her ear against the wall, eavesdropping.

After listening for a while...

For a moment, the complexion and eyes could not help but become a little strange.

Suddenly thinking of something, he couldn't help laughing out loud.

She thought of a couplet.

The first couplet is: Big fish eat small fish, small fish eat shrimp, shrimp eat water, and the truth comes out.

The second couplet is: the master presses the teacher's wife, the teacher's wife presses the bed, the bed presses the ground, the earth shakes and the mountains shake.

After listening to it for a while, the little girl rolled on the bed boredly, put on her earphones, played the cross talk again, and then slowly fell asleep after listening.

……

More than two in the morning.

Qin Luo was completely refreshed.

All the tiredness was swept away, and there was no sleepiness.

After practicing Wuqinxi until now, Qin Luo really felt that his desire for sleep was getting less and less.

If you really want to sleep, you can sleep.

But really not sleepy.

Qin Luo also took the time to learn a lot about the state of the body. It is said that there is a meditation method called mindfulness meditation, which keeps the spiritual platform clear and clear, and it is much better for mental rest than sleep.

I have never meditated before, but practicing Wu Qinxi may not have such effects.

at this time.

Closing his eyes, maintaining a posture of falling asleep, Qin Luo's thoughts sank into the system space.

cast sword.

……

I have read the history of sword casting in that book.

Qin Luo has some understanding of the context of sword casting.

However, it is impossible to compare the extent to which modern people have inherited this set of techniques, and how awesome the ancient people are.

In fact, Qin Luo thought about it himself.

Those ancient heat treatment processes, or the strength of materials, should not be as strong as modern ones, right?

Otherwise, what is the industrial revolution?

Compared with other handicrafts, the industry of sword casting is still closely related to "industry".

However, Qin Luo did not dare to be completely sure.

Because the cost is not on an order of magnitude.

The ancient master swordsmith may devote his whole life to forging a peerless sword with the support of the whole country.

It is hard to say that this extreme pursuit of precision and craftsmanship can be 100% imitated by modern times.

especially……

Those swords with almost mythical effects.

such as:

The Chengying Sword is one of the top ten famous swords in ancient times.

The reputation of this sword is simply unbelievable. Moreover, its special features are unprecedented and unprecedented.

This is a nearly invisible sword.

The Jiao bears the shadow, and the geese forget to return.

Could it be that in that era, the ancients had already mastered invisible materials?

Or, accidentally got a piece of material that can be "invisible"?

After all, invisibility in the modern sense cannot be detected by radar, but it can be seen by naked eyes.

And in many classic records, this Yingying sword seems to belong to the kind that cannot be seen with the naked eye under the sun.

It is more like using the characteristics of the material itself, coupled with the superb grinding process, to produce a refraction effect on light, which is almost transparent at a specific angle.

Oh.

This can be done with modern techniques and materials.

Could it be... glass?
Could it be that Chengying is a quartz sword?
Qin Luo's imagination was running wild.

Thinking in this way, it is very interesting to feel that myth and reality, ancient and modern, are intertwined in my mind.

Except for Chengying...

There are others.

Another example is Goujian Sword, the King of Yue.

Needless to say the name of this sword, unearthed more than 2000 years later, it can still maintain its sharpness and toughness, which is simply a myth.

Technology cannot explain.

It is said that the anti-corrosion material on the surface of the Yue King Goujian sword was discovered and patented by the West only after the [-]th century.

But more than 2000 years ago, the ancestors had already used it.

They may not understand the periodic table, but they know how to use it.

It's so magical.

Where are you going to make sense?
and……

Not only domestic...

In addition to China, in fact, in the ancient history of foreign countries, there are also some "magic soldiers" that can be called myths.

For example, in ancient Egypt, Tutankhamun's gold dagger.

After the dagger was actually unearthed, it was praised as "not a human thing."

According to the research of archaeologists, it is more than 1000 BC, the funerary object of the ancient Egyptian pharaoh Tutankhamun.

However, after testing by modern technology, the metal elements in this sword, except for gold, cannot be found on the earth.

Its material and composition are highly similar to meteorites in meteor showers.

It's just that where the meteorite is, because human beings' research on the sky is still limited, it is not yet possible to distinguish it.

The long river of ancient time has buried too many things.

What works?
what doesn't work?
What is essence?

What is dross?

What should be eliminated?

What should be inherited?

These are the main tasks of oneself, and they must be screened in detail.

Thinking about this...

Qin Luo now feels that, as far as sword casting is concerned,... material should be the king, and craftsmanship should be the supplement.

Take the iron sword as an example...

The sword that I broke during the day must be an iron sword, that's why it's so brittle.

This "Longquan Sword Records" says that iron swords are very difficult to produce famous swords.

Usually, the iron that everyone refers to is an iron-carbon alloy with a carbon content greater than 2.11%.

During the Spring and Autumn Period and the Warring States Period, the iron used was mainly white iron.

The difference between iron and steel is that:
Iron is very brittle, easy to crack when forged, and lacks toughness.

And steel is tough.

The so-called "smelting steel" that is often heard is fried steel, which is steel made by repeatedly folding and forging iron blocks.

After the Spring and Autumn Period and the Warring States Period, there were fewer legends about swordsmiths in history. It is estimated that they have changed from "swordsmiths" to "swordsmiths" with hammers on their wheels.

The difference in the strength of the material is enough to bridge the gap in the process.

To be more practical...

For example, if you cast the deck of an aircraft carrier, or the special steel used for aircraft blades, even if you don’t need to make it into the shape of a sword, you don’t need to cut it with a modern cast sword. The former will definitely win.

……

in the system space.

At this time, four teachers appeared.

Information about them also came to mind.

They are: Ou Yezi, General Mo Xie, and Feng Huzi.

have to.

They are all from the Spring and Autumn Period and the Warring States Period.

Ou Yezi and General Mo Xie are both famous existences, and many famous swords exist in the world.

The current Longquan swords are still hidden in the Palace Museum.

As for the wind beard...

Although there is no work handed down from generation to generation, it is forging swords, and it is the "queen sword casting consultant" of the King of Chu at that time.

After Qin Luo appeared in the system space, the four of them acted like a fully simulated artificial intelligence, and soon began to teach step by step.

Let's start with watching the sword.

All kinds of materials, shapes, and styles of swords are all presented, allowing them to be appreciated, played with, and identified.

And Qin Luo, at this time, quietly discovered his "shallowness" and "ignorance."

The swords they are familiar with, they don't even know, and even the impressions in history are quite different.

……

"This one, named Canhong, was entrusted by Prince Dan and made by Mrs. Xu. It was handed over to Jing Ke to assassinate King Qin's weapon."

"The Remnant Rainbow Sword is not so much a sword, but more like a dagger. Its material is neither gold nor iron, both soft and hard. When it is in its natural state, it is extraordinarily soft, but when it is suddenly exerted, it will instantly become hard and sharp. "

Wind Beard explained.

Qin Luo was stunned for a moment.

I go?

This……

It sounds amazing.

Moreover, it reminded Qin Luo of... science.

Anyone who has studied physics knows that there is a type of material called non-Newtonian fluid.

Non-Newtonian fluids produce weak resistance when the force is applied slowly.

But when the force is severe, the resistance will be very large, and even a solid form will appear.

Known as "eating soft but not hard", it is a real contradiction.

How similar is the characteristic to this sword?
"What material is this cast from?"

Qin Luo asked softly.

Feng Huzi was silent for a moment: "Made of flesh and blood, to cast this sword, four boys and girls were thrown into it."

Qin Luo: ...! ! !
Silent.

However, immediately, his body trembled suddenly, and a definition emerged in his mind.

Definition of non-Newtonian fluids.

Non-Newtonian fluids, half of which are concentrated solutions and suspensions of polymers.

In addition, most biological fluids belong to the defined non-Newtonian fluids.

Various body fluids such as blood, lymph, and cystic fluid in the human body, as well as "semi-fluids" like cytoplasm, all belong to non-Newtonian fluids.

This……

does it matter?

Qin Luo thought carefully and was terrified.
