After the whole sect traveled to ancient times, I led the rebellion

Mu Qing had inquired before and knew that the Tianchi Dynasty used vertical furnaces to smelt iron.

The main method of ironmaking in China in the 21st century is blast furnace ironmaking.

Iron is more susceptible to rust than steel.

Steel has high strength and good plasticity and toughness.

In China, steel is widely used in all aspects of life.

Since he had to smelt iron anyway, Mu Qing chose to do it in one go.

Mu Qinghui's theory of traditional steelmaking.

Mu Qing also has Shen Moyan and Jiang Ji as backup.

The conditions that cannot be met in this era can be met by another element, Reiki, which is beyond the scope of science.

One of the steps in traditional steelmaking is blast furnace ironmaking.

The main raw materials for blast furnace ironmaking are coke, iron ore and limestone.

Iron ore contains silica, which is converted into slag by limestone.

Coke reacts with air to produce carbon dioxide, which generates heat to maintain the high temperature of the blast furnace.

The carbon dioxide combines again with the coke to form carbon monoxide, providing the reducing agent for the reaction.

Inside the blast furnace, the carbon monoxide continues to react upward with the iron ore.

The ferric oxide and carbon monoxide in iron ore react at high temperature to produce iron and carbon dioxide.

The chemical equations for these reactions can be found in junior high school chemistry.

The generated molten iron has a high density, while the slag at the bottom of the blast furnace has a low density, so the slag will float on the molten iron.

The molten iron obtained at present is considered pig iron.

From iron to steel, there are the frying steel method and the pouring steel method.

The pouring steel method is easier to master than the frying steel method.

Pour molten pig iron onto the wrought iron sheet.

Wrought iron becomes steel due to the penetration of carbon, and pig iron becomes steel due to decarburization.

The essence of tempering steel is the method of frying steel.

This method can greatly improve the quality and output of steel.

The theory is feasible and practice begins.

A few days after Mu Qing arrived in Huang County, he had a clear understanding of the distribution of nearby mineral resources.

There are iron ore and limestone mines, but the coal mines are far away from Huang County and are distributed near Guangsha County.

There are no signs of limestone or coal mining.

Coke is produced from coal mines.

If you want coke, you have to make coke.

The temperatures required for coking and steelmaking cannot be achieved by burning wood alone.

but it does not matter.

If the blast furnace cannot reach the required temperature due to material reasons, it will be Shen Moyan and Jiang Ji's turn to take the stage.

Although both of them were sword cultivators, they also practiced other basic techniques after joining the Tianjian Sect.

Although the damage caused by fire spiritual energy is not as high as that of a cultivator with fire spiritual roots, it is still easy to maintain high temperature using the Divine Fire Technique.

In fact, Mu Qing still felt a little guilty.

If Shen Moyan and Jiang Ji were placed in the world of cultivation, each would have higher talent than the other.

Such a gifted child of destiny did not practice, but was caught by Mu Qing to be a blacksmith. If those old bones in the world of cultivation knew about this, they would definitely complain about it.

How can you kill a chicken with a bull's knife?

However, although Mu Qing felt guilty, he still appeared very calm.

The eldest brother had to raise children, so she usually provided them with food and clothing, and taught them knowledge.

These things cost money. My senior brother hasn't paid off his debt yet, so there's nothing wrong with working for her.

As for the second brother.

Mu Qing saw Jiang Ji a few days ago and discovered that his cultivation had sprinted from the early stage of Golden Core to the peak stage of Golden Core, and he was almost breaking through.

Iron and steel smelting and the like might even help to promote the proficient use of spiritual energy.

She is doing this for Second Brother's own good.

It only took a quarter of an hour for Mu Qing to go from feeling guilty to straightening his back and handing over the new work tasks to Shen Moyan and Jiang Ji.

Master Xu, who was obsessed with studying biochemistry, did not forget to help Mu Qing contact students from farming families, and even contacted a distant cousin of the Mohist school.

Mu Qing quickly came to meet these technical workers (bushi) who were about to shine for Huang County.

Mu Qing slightly modified the words he had used to persuade Master Xu that day and repeated them to the farmer student with deep emotion.

Mu Qing didn't have to say anything, these students from farming families decided to move to Huangxian with their families and become part of the laboratory's thriving workforce.

The development of biology and chemistry in this world finally ushered in new vitality after Mu Qing.

Once Mu Qing has taught all the theoretical knowledge to Master Xu, he can get out of the laboratory earlier.

And the great subject of physics still depends on Mohism.

Mu Qing has been coveting the Mo family's mechanical devices for a long time.

China has a history of 5,000 years.

Starting from Han.

With the implementation of the policy of abolishing all schools of thought and respecting Confucianism alone, the Mohist school gradually disappeared due to its noble ideas and strict requirements.

Mu Qing had read an incomplete version of Mozi, in which some chapters were lost for various reasons.

And the Mohist mechanical techniques have disappeared in the long river of history.

The Tianchi Dynasty is like a parallel universe during the feudal period on Earth.

The mechanical devices of the Mohists, such as the crossbow chariot, windlass, and pulley, were used in production and military affairs; these objects alone, which have been recorded in history, can be regarded as sacred artifacts.

Not to mention that the Mohists were also good at arithmetic and physics.

During the early days of Western physics, the Mohists had already conducted experiments on pinhole imaging.

This made Mu Qing more curious and awed about the mysterious Mohist school.

Xu Yu, a distant cousin of Master Xu, came to Huangxian in part because of what Master Xu had seen and heard about Huangxian in his letter.

Xu Yu had never found the multiplication table mentioned in it in any other book.

Another reason for coming to Huang County was because the Mohist school had strict rules, but Xu Yu acted casually. He majored in Taoism before joining the Mohist school.

Xu Yu followed the old Zhuangjia's casual nature and became more unruly. Asking him to abide by the strict rules of the Mohist school was like making him itchy all over and very painful.

However, Xu Yu still stayed in Mohism for a few years and learned all the techniques that interested him.

Huang County can temporarily be Xu Yu’s next stop.

Mu Qing's eyes lit up when he saw Xu Yu.

A living disciple of Mohist school!

Xu Yu lived according to his heart, and Mu Qing did not promise Xu Yu a huge fortune or anything right away.

It's not like moral blackmailing the farmers. Ahem, how can we call it moral blackmailing for the sake of the people?

Withdraw. Withdraw.

Xu Yu is not very old, just over 20 years old.

He sat on the chair without any image, and without waiting for Mu Qing to come in, he started reading the book on the desk with great interest.

Mu Qing walked closer and saw that the book Xu Yu was holding was a revised and simplified version of the elementary school mathematics textbook.

When Xu met Mu Qing, he did not look down on him. He just glanced at him and continued to read.

Xu Yu hadn't taken care of his hair for many days, and the black hair in front of his eyes barely covered his eyes. If it was longer, it would cover half of his face.

Mu Qing has been in this world for so long, and this is the first time he has seen a otaku version of a boy in the Tianchi Dynasty.

She looked at Xu Yu silently.

Xu Yu did not take the initiative to say hello, nor did he speak.

It was as if the elementary school textbook in his hand had some magical power that made Xu Yu ignore Mu Qing's existence.
