The Master of the Kingdom

Time turned back to when Su Yi just got the piano manufacturing drawings. After a false alarm, Su Yi began to look at the piano manufacturing drawings.

This drawing is very simple, but the accuracy requirements for the data are quite high.

However, there is a length mark of centimeters and millimeters on the drawing. Through this, a more accurate ruler can be made. Just leave this to the craftsman.

The piano drawings that Su Yi pulled out, although the materials used are more precious to achieve the best sound quality, but there are royal inventory and Mu Yan's help, which is a trivial matter. The only difficulty lies in the strings.

The piano strings of modern top brands are made of low-carbon steel wire, a special alloy, which is very ductile and not easily deformed.

For this era, this technology is naturally too advanced.

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

After studying the drawings, Su Yi felt that the manufacturing process was too complicated. Having difficulty finding the emperor's father, Su Yi immediately found the emperor and said that he finally came up with the blueprints of the commonly used musical instruments before, and now he asked the emperor's father to help him make this kind of musical instrument called "piano" for his son.

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

When Su Yi gave the emperor the drawing, the emperor felt that his son was naughty again.

This is to make myself a musical instrument for him, obviously I want to offer a new metal formula!

Yes, the emperor was talking about strings.

Su Yi’s design drawings show how the parts are made, and the string material is very demanding, so there are instructions on how to smelt it. Not to mention whether the metal called low carbon steel can be made into weapons, but the steelmaking method that is most likely to be achieved under the technical conditions of this world is enough to make the emperor excited and sleepless at night.

China was able to make steel long ago. Before the first industrial revolution, China's steel manufacturing technology led the world.

In the Western Han Dynasty, the steelmaking method used was ironmaking and carburizing steel, that is, cast iron was heated and beaten in a charcoal fire to allow carbon elements to slowly penetrate into the cast iron. The distribution of carbon elements in this steel is uneven and the texture is not good. Therefore, the working people in ancient China repeatedly heated and folded cast iron to make the texture of steel more uniform. This is the legendary hundred steelmaking.

Hundreds of steel-smelting was laborious and time-consuming. During the period from the end of the Eastern Han Dynasty to the Northern and Southern Dynasties, the steel frying method and the steel filling method were invented, and the quality of steel was greatly improved.

But now, steel speculation is not popular, and the extremely long steel-making weapons are only available in the possession of famous generals or wealthy families.

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 war, he had heard that someone had mastered more advanced weapons forging methods, but after he became the throne, he issued notices and no one came.

The emperor guessed that these technologies were probably in the hands of local tycoons.

I just don't know when the local tycoons who master this technology are willing to take it out and what conditions are needed. Or, when will this technology leak?

There are several methods for forging steel in the drawings of the steel used for forging strings given by Su Yi, and the merits and demerits of each are evaluated.

Su Yi was also surprised when she watched it.

He always felt that the things drawn in this lottery were a bit strange. Does it need to be written in such detail?

Or does it mean that the system thinks that if you don't write detailed points, you can't forge the required strings, and it feels uncomfortable?

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

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

Su Yi later guessed that it might be a bug in the system that caused this kind of "fault".

However, the bug was not recovered, and Su Yi took a big advantage this time.

(Probably) In order to make piano strings, the system drawings enumerate all possible ways to improve steel production and quality under current technology, and provide several steel formulas that can withstand high temperatures, which greatly improves the steelmaking furnace’s performance. Degree of heat resistance.

The steel frying method and the steel filling method are directly 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 Beth during the first industrial revolution, and was the beginning of modern steelmaking. 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 draw this time directly forcibly raised Hua Guo's steelmaking level for nearly 1,900 years, and it was really a bug that shook the world.

Su Yi knows how to separate oxygen from the air, but whether it is deep freezing or other, the current technology is indeed unable to achieve. Although Su Yi is a technical house, he has not cared about how to make steel, so even if oxygen is separated, he doesn't know how to improve.

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 capable people who will use his world-proven scientific knowledge from his books to contribute to the development of science and technology in China.

It would be better to keep China at the world's leading level without experiencing that humiliating century.

But who can tell what happened after a thousand years? In his time and space, China has been standing at the top of the world for thousands of years, only a few hundred years behind. Who knows if what he wrote didn't let the younger generations of China awaken, but let people abroad awaken them, and then use his scientific theories to benefit their country, and China is falling behind faster?

Su Yi can only say that he has tried his best and can only do this step.

After the emperor got the new steelmaking method, he was first ecstatic and then worried. Will Su Yi be condemned by God if he takes out such things that are against the sky?

Su Yidao, he just made a musical instrument, and didn't do anything, he wouldn't.

The emperor thought to himself that his son would really take advantage of heaven. But I don't know if I can succeed in this loophole.

The emperor was probably the crow's mouth. Soon after he told Su Yi, something went wrong with Su Yi. No, to be precise, it wasn't that Su Yi had an accident, but someone else thought that Su Yi had an accident.

There are more thunderstorms in summer, and Su Yi wants to experiment with thunder and lightning devices on a whim. The purpose of this experiment is to draw down the lightning spots in the sky, and then what is the effect... Well, there is no other effect.

What is the role of the technology house experiment? Fun is enough.

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

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

Su Yi was standing under the eaves where he had installed lightning protection devices, observing that the tree was chopped, and then jot down some data that no one understands except himself.

That night, the people in the capital saw the scene as described in the deified script, like a catastrophe.

The thunder spots in the sky were concentrated in the sky above Su Yi's yard, and they kept going down a lot. The scene was spectacular and terrifying.

After that night, it was rumored that Su Yi had violated the rules and was killed. People in the capital are full of hearts.

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

Mu Yan was by the side when he was doing the experiment.

After Mu Yan came into contact with Su Yi's various experiments, he was deeply fascinated by the magical effects of experiments. He thought, no wonder there are so many people indulging in alchemy. Don't talk about what you get, this process is attractive enough.

When Su Yi said that he wanted to use thunder and lightning to observe, after repeatedly confirming that there was no danger, Mu Yan was very bold and gave up his life to accompany Su Yi.

Then the two sat under the eaves, watching the old tree in the courtyard being struck by lightning. Is this moral decay or...

Keke, the topic is off the track.

After Mu Yan watched the experiment, he began to clean up Su Yi's mess. For example, going out for a stroll shows that he is safe and sound, such as going to the palace to report safety.

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

Su Yi agreed.

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

The news that he was okay had already let his servants stay at the gate of the palace overnight, and reported it to the empress as soon as the gate was opened, lest the empress slept with him and heard that Su Yi was struck by lightning and scared of myocardial infarction.

Actually, I was scared after God.

They didn't believe that Su Yi was experimenting on his own. The emperor was very convinced that this must have something to do with the steelmaking method.

The emperor waited for Su Yi in the palace very nervously.

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

The queen was even more sturdy and wanted to take off Su Yi's clothes on the spot, frightening Su Yi.

The imperial doctor is also in place. After they checked, they concluded that Su Yi had consumed too much energy and needed to rest.

After thinking about it for a long time, Su Yi could only figure out that it was probably because he was busy working on this experimental device for a few days.

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 empress's wife to call Mu Yan to testify, and he was really fine.

After Mu Yan arrived, he said that he felt uneasy and forced Su Yi to take him in, but he fell asleep as soon as he entered the door, and did not wake him up even by the sound of thunder and lightning. He didn't wake up until the thunder and lightning was over, and then learned of the matter from the subordinates, and hurriedly sent someone into the palace to report his safety.

Isn't this nonsense?

Because this experiment is very dangerous to others, the yard that Su Yi used to do experiments on weekdays has been installed and can be locked from the inside. So the servant doesn't know what happened inside.

Su Yi informed the housekeeper and nurse in advance that no matter what happened in the yard, they were not allowed to panic or come in. He's okay, if someone comes in, it's okay.

Therefore, the subordinates only dare to wait outside, and dare not enter to disturb.

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