prosperous national teacher

Back in time, when Su Yi first got the piano manufacturing drawings, after a false alarm, Su Yi began to look at the manufacturing drawings.

This drawing is quite simple, but the accuracy of the data is quite high.

However, there are centimeter and millimeter length marks on the drawing, through which, a more accurate ruler can be made.Just leave it to the craftsman.

The piano blueprint drawn by Su Yi, although the materials used are relatively precious in order to achieve the best sound quality, but there are royal stocks and Mu Yan's full support, this is a trivial matter.The only difficulty is the strings.

The piano strings of modern top brands are all made of low carbon steel wire, which is a special alloy with strong ductility and not easy to deform.

For this era, this technology is naturally too advanced.

Although Su Yi has drawings made of this alloy, it is definitely not up to standard now.It can only be said that the sound quality is definitely not as good as that of modern pianos.

After Su Yi studied the drawings, he felt that the manufacturing process was too complicated.Having difficulty finding the emperor’s father, Su Yi immediately found the emperor, saying that he finally figured out the blueprint of the musical instrument that he used to use in the past, and now asked the emperor’s father to help him make this instrument called "piano".

At first, the emperor thought to himself, isn't it just a musical instrument, no matter how complicated it is, he can make it for his son.

When Su Yi gave the blueprint to the emperor, the emperor felt that his son was being mischievous again.

This is not to let him make musical instruments for him, it is obviously to present the new metal formula!

That's right, the emperor was talking about the strings.

Su Yi's design drawings include the production methods of the parts, and the material of the strings is very demanding, so there are even instructions on how to smelt them.Not to mention whether the metal called low-carbon steel can be made into weapons, but the steelmaking method shown above, which is most likely to be achieved under the world's technical conditions, is enough to keep the emperor awake at night with excitement.

Huaguo was able to smelt steel a long time ago.Before the first industrial revolution, Huaguo led the world in steel manufacturing technology.

In the Western Han Dynasty, the steelmaking method used was iron-making and carburizing steel, that is, cast iron was heated and beaten in a charcoal fire, so that carbon elements slowly infiltrated into the cast iron.The carbon element of this steel is unevenly distributed and the texture is not good.Therefore, the working people in ancient China repeatedly heated, folded and forged cast iron to make the texture of the steel more uniform.This is the legendary hundred steelmaking.

Steelmaking is labor-intensive and time-consuming. During the period from the end of the Eastern Han Dynasty to the Northern and Southern Dynasties, the method of frying steel and pouring steel was invented, and the quality of steel was greatly improved.

But now, frying steel is not popular, and only famous generals or wealthy families have stockpiles of extremely time-consuming hundred-steel-making weapons.

Metal casting technology is basically related to the national strength of a country.This is not only military strength, good metal materials can be used in many places.

When the emperor was leading the army to fight, he heard that someone had mastered more advanced weapon forging methods, but after he ascended the throne, he issued notices widely, but no one came.

The emperor guessed that these technologies were likely to be in the hands of local wealthy families.

I just don't know when the local wealthy families who have mastered this technology are willing to take it out, and what conditions are required.Or, when will this technology leak out.

In the drawings given by Su Yi for the steel used for forging the strings, there are several methods of forging steel, and each evaluates its pros and cons.

Su Yi was surprised when he saw it.

He always felt that the things drawn in this lottery were a bit strange.Do I need to write in such detail?

Or does the system think that if you don't write more details, you can't forge the strings you need, and it feels uncomfortable all over?

Su Yi really wanted to communicate with the system, but he found that the system seemed to be dead, and it had been sleeping all the time, and he didn't know what went wrong.

After the system restarted, there was no big bargain like this lottery.

Su Yi guessed later that it might be a bug in the system that caused such a "mistake".

However, the bug was not recovered, and Su Yi took advantage of it this time.

(Probably) In order to make piano strings, the system drawings list all possible methods of improving steel production and quality under the current technology, and provide several steel formulas that can withstand high temperatures, which greatly improves the steelmaking furnace. Heat resistance.

The steel frying method and the pouring steel method are directly the finished products that have been perfected and tested by later generations, and the converter method is also attached.

The converter method was invented by the British Bass in the first industrial revolution, and it is the beginning of modern steelmaking methods.I don't know because the technology in this world has not yet developed to the point where oxygen can be separated from the air. The final drawing recommends the open-hearth steelmaking method.

Su Yi's lottery draw this time directly forcibly raised the level of steelmaking in Huaguo by nearly 900 years. It was really a shocking bug.

Su Yi knows how to separate oxygen from the air, but whether it is deep freezing or other methods, the current technology really cannot achieve it.Although Su Yi is a technical geek, he didn't care about how to make steel, so even if he separated oxygen, he didn't know how to improve it.

However, Su Yi decided to write down all the scientific theories he knew and publish them on a large scale.I hope that in the future, there will be able people from his books to apply the scientific knowledge verified in his world to contribute to the scientific and technological development of Huaguo.

It is best to keep Huaguo at the leading level in the world and not go through that humiliating century.

But who can say clearly what will happen after a thousand years?In his time and space, the country of Hua has been standing at the top of the world for thousands of years, only falling behind in the last few hundred years.Who knows if what he wrote didn't enlighten the descendants of Huaguo, but enlightened people from abroad, and then used his scientific theories to benefit his own country, and Huaguo fell behind faster?

Su Yi can only say that he has tried his best, and this is the only way he can go.

After the emperor got the new steelmaking method, he was ecstatic at first, and then worried.If Su Yi took out such a heaven-defying thing, would he be punished by God again?

Su Yi said, he just made a musical instrument, and he didn't do anything, so he won't.

The emperor thought to himself that his son would really take advantage of Heaven's loopholes.But I don't know if this loophole will be successful.

The emperor probably had a crow's mouth. Not long after he told Su Yi, something happened to Su Yi.No, to be precise, it wasn't that something happened to Su Yi, but others thought that something happened to Su Yi.

There are many thunderstorms in summer, so Su Yi decided to experiment with a lightning-inducing device on a whim.The purpose of this experiment is to lure down the thunder dots in the sky, and then what effect will it have... well, nothing else.

What is the purpose of the experiment of the technical house?Funny enough.

Then Su Yi completed the experiment during a thunderstorm, attracting lightning from the sky and splitting the poor old tree in the middle of the courtyard.

What's more pitiful is that the old tree was split many times during the whole thunderstorm.

Su Yi stood under the eaves of his own lightning protection device, observed the tree being split, and then recorded some data that no one could understand except himself.

That night, the people in the capital saw the scene as described in the deified storybook, as if they were going through a catastrophe.

The thunder spots in the sky concentrated over Su Yi's courtyard, and they continued to strike down many times.The scene was magnificent and terrifying.

After that night, it was rumored that Su Yi violated the rules of heaven and was hacked to death.People in the capital are excited.

On the second day, in order to show that he was safe and sound, Su Yi had to go to the palace in an open carriage to report his safety.

When he was doing the experiment, Mu Yan was at the side.

After Mu Yan came into contact with Su Yi's various experiments, he was deeply fascinated by this kind of experiment that would produce miraculous effects.He thought, no wonder so many people are addicted to alchemy.Not to mention what is produced, the process is attractive enough.

When Su Yi said that he would lead the thunder and lightning to observe, after repeatedly confirming that there would be no danger, Mu Yan boldly risked his life to accompany Su Yi.

Then the two sat under the eaves, watching helplessly as the old tree in the courtyard was struck by lightning.Is this a loss of morality or...

Whoops, off topic.

After Mu Yan watched the experiment, he started to clean up the mess for Su Yi.For example, go out and wander around to show that he is safe and sound, such as going to the palace to report that he is safe.

"Your Majesty and Empress must be terrified." Mu Yan said, "Go early tomorrow morning!"

Su Yi agreed.

In order to show that he was alive and well, he deliberately chose to enter the palace at dawn.

As for the news that he was fine, the servants had already ordered the servants to guard the gate of the palace overnight, and reported to the empress as soon as the palace gate was opened, lest the empress would hear that Su Yi had been struck by lightning and had a myocardial infarction when she woke up.

In fact, the empress was still frightened.

They didn't believe that Su Yi did the experiment by himself.The emperor was very sure that this must have something to do with the steelmaking method.

The emperor was anxiously waiting for Su Yi to come in the palace.

When Su Yi came, the empress, prince, and second prince were all there.

The queen was even tougher and wanted to take off Su Yi's clothes on the spot, scaring Su Yi very much.

The imperial physician is also in place.After their inspection, they came to the conclusion that Su Yi had exhausted too much energy and needed to rest.

Su Yi thought about it for a long time, but he could only come to the conclusion that it was probably because he was busy working on this experimental device for a few days, and stayed up all night last night, due to lack of sleep.

But this conclusion is probably only believed by him and Mu Yan.

What made Su Yi even more depressed was that he asked the emperor's father and the queen's mother to call Mu Yan to testify that he was really fine.

After Mu Yan came, he said that he felt uneasy and forced Su Yi to bring him in, but he fell asleep as soon as he entered, and even the sound of thunder and lightning didn't wake him up.He didn't wake up until the thunder and lightning were over, and then he learned about it from his subordinates, and quickly sent someone into the palace to report his safety.

Isn't this bullshit?

Because this experiment is very dangerous to others, the yard where Su Yi usually uses for experiments has a door installed, which can be locked from the inside.So the servants don't know what happened inside.

Su Yi notified the housekeeper and nurse in advance, no matter what happened in the yard, don't panic and don't come in.He's fine, if someone comes in, it's fine.

Therefore, the servants only dared to wait outside, and did not dare to enter to disturb.

And what Mu Yan did, whether he was asleep or awake, they didn't know.
