Lin Ran is the most famous teacher at Guanshishan Academy Medical College.

Even if it is placed in the entire Tang Dynasty, in addition to his master Sun Simiao, his fame is also very famous.

With his development, many people have said that surgery has been accepted by him.

However, during the years of surgery, Lin Ran has always had a heart disease that has not been resolved.

"Teacher Yao, although these surgical instruments made of special steel have better rust resistance than before, they still rust."

The rust of steel is a headache for no matter which industry it is.

Some parts can be used to relieve rust by painting, etc., but for the operating rooms of medical schools, it is difficult to use this method of surgical instruments.

"Teacher Lin, the research and production of this special steel involves theoretical issues in all aspects. I just heard His Highness the King of Chu mention it before, saying that the steel smelted after adding some special ores may become stainless steel.

But what ore is added and how much ore is added is a big question, and countless experiments are required to find the rules.

Our special steel institute's experiments are not like those of the School of Calculation, which can be completed with almost no money.

For us, the iron in each furnace is a cost. To speed up the research, we can only continuously increase the frequency of experiments.”

Yao Mosan is a star in the mining industry of Guanshishan Academy and has very high attainments in smelting ore.

So he is now the head of the Special Steel Research Institute of Guanshishan Academy.

"Our medical school needs special steel that can be rust-free, the bearing research institute needs special steel that is more wear-resistant and harder, and the machinery workshop needs special steel that can be installed on steam engine equipment to process steel, but until now, we still lack the understanding of special steel.

You said we would like to ask the King of Chu to come down and our academy to give you a special speech on special steel?”

After hearing Yao Mosan's words, Lin Ran suddenly felt that there was a shortcut to try to walk.

If you encounter any special topics, go to Li Kuan.

This is already a habit for many people in Guanshishan Academy.

Over the years, Li Kuan has not disappointed everyone.

Although he often cannot give a direct solution, he can always give you some tips and point you out some research directions.

"It's OK, but various basic experiments cannot be avoided. In this regard, students may need to increase their investment in the Chemistry Academy. Only when we have a further understanding of the various chemicals and metals that exist in this world can we make materials that meet our needs."

As an expert in mining, Yao Mosan has a deeper understanding of the various materials that exist in this world.

In addition to the familiar gold, silver, copper, lead and tin, he is sure that there are other metals in this world.

There are even more types of metals in this world that have not been discovered by everyone than everyone is familiar with.

But these things require time to prove them continuously.

"This is no problem. His Highness the King of Chu has always been very willing to invest in Guanshishan Academy."

When Lin Ran said this, he was about to clean up and go to the Chu Palace.

...

Li Kuan's chemistry is relatively average.

Although we can still memorize the names of more than twenty elements in the periodic table so far, we have almost forgotten many basic theories.

Fortunately, the previous rewards included the periodic table of chemical elements.

With this periodic table of elements, Li Kuan can also blow water with others for a long time.

For example, when seeing hydrogen, Li Kuan immediately could talk about it for half a day, and then introduce his understanding of hydrogen and processing methods.

The other elements are similar.

Although there are many words that Li Kuan cannot even recognize, it doesn’t matter. At worst, the discovery of the periodic table of elements can be attributed to a Taoist priest passing by.

Of course, this kind of confidential thing that involves core craftsmanship will not be held in the public speech at Guanshishan Academy.

Even if Lin Ran and Yao Mosan came here to ask for help, Li Kuan only agreed to explain to the graduate students of the School of Chemical Science and Technology of Guanshishan Academy and the teaching staff in related research institutes on a small scale.

"Prince, do you mean there are more than a hundred elements in this world, and all the materials are made up of various elements?"

Li Kuan's theory was thrown out and immediately caused a huge reaction.

Although it is only a small-scale teaching, there are also quite a lot of people.

All of these people are core talents of Guanshishan Academy.

"That's right, in fact, you can find this rule by just studying it more. For example, iron smelting is actually to let the iron oxide and carbon undergo chemical reactions, extract the metal iron, and carbon dioxide will be produced in the middle.

As for the most common water, it is the material directly generated after the combustion of oxygen and hydrogen.

I have also done experiments in the academy before, and everyone has proved that the existence of hydrogen and oxygen, and various other chemical reactions, are in line with these rules."

In recent years, Li Kuan has proposed some new theories for Guanshishan Academy every few days.

After years of accumulation, many theories have taken root and sprouted.

I still remember when I first proposed the concept of air and oxygen, almost few people in the entire academy believed it.

However, to the present, Guanshishan Academy has a production workshop dedicated to making hydrogen and oxygen.

Even in Guanshishan Academy Medical College, we have been studying how to use oxygen in the treatment of patients to improve the survival rate of some patients.

So although Li Kuan’s lecture content today was thrown out more, everyone immediately accepted it after simple digestion.

"His Royal Highness, does the existence of this periodic table of elements mean that there are still many metals in this world waiting for our discovery?"

"Of course! The metals that everyone often comes into contact with now are just a fraction. Different metals have different properties. If they can be combined in a suitable proportion, some materials with special properties can be obtained.

For example, the stainless steel I mentioned before, I think it may be a mixture of iron and other or concentrated metals. As long as you experiment more, you will definitely find these things."

Li Kuan had no way to tell everyone that by adding metals such as tungsten, manganese, nickel, vanadium, etc. to steel, you can get various special properties of materials.

Because these metals are still unfamiliar to the Tang Dynasty.
