"Your Majesty, how is this blast furnace??"

When Du Pre smiled and showed Cao Chao the blast furnace in front of him, Cao Chao was startled and hurriedly stepped forward, "Ma Gong! Come down! Come down! ”

At this moment, Ma Jun is standing on top of the blast furnace.

Cao Chao visually inspected it, and this blast furnace was more than two meters high and more than three meters long.

When Ma Jun saw the emperor suddenly arrive, he also hurriedly climbed down from the blast furnace.

"Minister, minister, minister to see Your Majesty, the minister is not intent on trespassing, I hope that Your Majesty will forgive your sins!"

According to the etiquette law, Ma Jun cannot stand taller than the emperor, and the height of the building in Luoyang cannot exceed the palace.

But Cao Chao didn't ask about this, he was afraid that Ma Jun would fall down.

This person is a lot old, and if he falls, he can set back Dawei's scientific level for more than twenty years.

He hurriedly said: "Ma Gong, what are these words, I am worried that I will hurt you by falling, don't do dangerous things in the future, didn't I send someone to you?" ”

"Yuan Kai?!"

Cao Chao looked at Du Yu sharply, with dissatisfaction in his eyes.

Du Yu hurriedly lowered his head and said, "Your Majesty, it's me who didn't handle things well."

Ma Jun stammered and said: "Don't blame Du Shangshu, don't blame Du Shangshu, I want to do it myself, young, young students, lack of work, lack of experience, so I do it myself, Du Shangshu, arranged, the people are very good." ”

Cao Chao held his hand and said sternly to Du Yu: "Send more people to follow Ma Gong's side, he just wants to go up, and there must be two people around him to support me!" ”

"If something happens to Ma Gong, don't do it anymore!"

Although Ma Jun also knew that Du Yu was the emperor's confidant, and his words were also to appease himself, but when he heard the emperor say this, he was inexplicably moved in his heart, he was not a big man when he was in the temple, and now he is an ordinary retired old man, and he can get such a love from the emperor.

Du pre-received the order and repeatedly said that he would never let the old man take risks in the future.

Cao Chao followed them and looked at the blast furnace in front of him.

Blast furnace smelting method.

Iron and steel manufacturing in ancient China has always been at the forefront of the world, and the second large-scale breakthrough in steel smelting technology occurred during the Wei, Jin, Southern and Northern Dynasties.

In fact, during this period, many science and technology have made great breakthroughs.

Cao Chao guessed that this was probably because of the drastic changes in the social atmosphere and the decline in the binding force of etiquette in the Later Han Dynasty.

But in the Wei and Jin dynasties, no one cares about you when you grab food with pigs, and you still boast of being bohemian and uninhibited, what's wrong with a little hobby of scientific invention? No one cares at all.

As a result, scientists came out in large numbers, and the children of the big clan had nothing to do and began to engage in various hobbies.

Ma Jun is also a child of the big family, Fufeng Ma, Zheng Xuan's original teacher Ma Rong is from this Fufeng Ma clan.

In the Taiping period of the Later Han Dynasty, if Ma Jun dared to put aside his family scriptures and not ponder, and ran over to engage in scientific research, the elders in his clan would be able to break his legs!

Cao Chao talked to Du Pre about this smelting method.

Ma Jun really didn't disappoint Cao Chao.

At this moment, Ma Jun was explaining the blast furnace in front of him to Cao Chao.

Ma Jun changed the method of charcoal smelting to coal, and in addition, he added a "fire wall" to the blast furnace.

This greatly increased the carbon content in pig iron, and in addition, he was also improving the method of boiling steel, which was also a new thing that appeared in the Wei and Jin dynasties, and only appeared in the late Eastern Han Dynasty for the first time in the official record, and was widely used in the Wei and Jin dynasties.

Cao Chao listened to Ma Jun's narration and was extremely excited.

Compared with those farm tools, the improvement of this smelting technology is really too huge for the entire Great Wei.

After the smelting technology is improved, whether it is agricultural tools or weapons, it can be greatly improved.

The improvement of the quality of agricultural tools will accelerate the development of agriculture, and the improvement of the quality of weapons is needless to say.

When the weapon of the Wei State armor collided with the weapon of the Shu State armor, the weapon of the Shu State armor was cut off, what was that scene??

The technical crushing, coupled with this high-pitched morale, the Shu State took the lead in fighting the Wei State??

That is to say, Cao Chao's qi cultivation kung fu is good, otherwise, he would have to raise his head and laugh at this moment.

The power of science.

His eyes when he looked at Ma Jun became softer and softer, he just told Ma Jun some ideas, including saving heat and the like, and the rest of the things were all made by Ma Jun himself through practice.

He remembered that there were actually scientists in Shu and Wu, but they were not allowed to be reused.

But I can't remember the name, but it doesn't matter, just wait until these two countries are destroyed, and then recruit them.

Cao Chao said with a smile: "In addition to this smelting, there is also mining, and you can come up with a better way." ”

"I don't know if Ma Gong has ever watched "Fan Zi Jiran"?"

"Naturally, I've seen it."

Cao Chao said with a smile: "It is recorded in this book that saltpeter comes out of Longdao and those who are good at serving powder today like to refine all kinds of loose medicine to eat."

Hearing this, Du Yu's face changed greatly, and he hurriedly said: "Your Majesty, this Zhusan is definitely not a good thing. ”

"Don't be afraid, I don't want Ma Gong to help refine the medicine, I want Ma Gong to think about another thing."

The history of gunpowder is actually very long, the first record of gunpowder formula in history was in the Sui and Tang dynasties, and gunpowder was officially used in warfare at the end of the Tang Dynasty.

In other words, it is very likely that gunpowder technology was also an invention of the Northern and Southern Dynasties.

In fact, this is easy to understand, after all, there are a lot of practitioners in this era, everyone in this era talks about metaphysics, they believe that ghosts and gods become immortals, and the book of Jin is full of ghosts and gods.

In the process of their alchemy and seclusion to seek immortals, they found that several minerals could not be burned together, and as soon as they were burned, they immediately became immortals, and then this thing was recorded.

But this kind of invention is improved step by step, and none of the four major inventions appeared suddenly, all of them have been explored and developed for a long time.

From the appearance of gunpowder to its military use, it took more than 100 years.

Cao Chao didn't expect Ma Jun to suddenly make gunpowder, and use this thing to blow up the city wall of Shu.

But the sooner it appears, the sooner it will be applied to the military.

Even if Cao Chao can't use it in his life, future generations will be able to use it sooner or later.

He talked to Ma Jun about his thoughts, and Du Yu was also listening.

Du Yu is also a family heirloom, but he is very interested in these things.

It seems that people in this era like to have a little hobby.

When Cao Chao left from here, Du Yu followed behind him, still praising Ma Jun.

Cao Chao opened his mouth and said: "You can't put everything on Ma Gong alone, you have to recruit more talents like Ma Gong, my Great Wei, can't you find the rest of the famous skills?" No matter how much money it costs, you have to recruit me, and you have to invite me. ”

"I know you're busy, but you've just seen how many problems can be solved with such a large blast furnace? How big is the lift? ”

"Just the replacement of agricultural tools can make the treasury full of grain!"

"You can't take it lightly."

"Yui!!"

At this moment, Zhonghui's mansion.

There were dozens of people standing in front of Zhong Hui, their faces a little solemn.

Zhong Hui said seriously: "Remember what I said? ”

"Remember that Your Majesty Zhong Gong, the only thing that Shu needs to be afraid of is Zhuge Zhan, and the rest of the people are not worried."

"Jiang Wei is not a threat to Great Wei, he is definitely not General Deng's opponent, but Zhuge Zhan relies on his father's prestige, the soldiers of Shu are very admired by him, and the people support him, he is extremely talented, if the emperor of Shu begins to reuse this person and let him replace Jiang Wei, it will be a disaster for Wei!"

These people repeated Zhong Hui's words.

Listening to these words, Zhong Hui felt disgusted.

Zhong Hui really won't pull down his face to give others a long reputation, and he is even more reluctant to use himself as a step to lift others up.

However, for the sake of business, Zhong will endure it!

Jiang Wei is difficult to deal with, and this person's desire to attack is very strong, although Shu may not be Wei's opponent, but Wei is not willing to be suddenly attacked by Shu.

Compared with him, Zhuge Zhan is too far behind.

If Zhuge Zhan can replace Jiang Wei, Zhong Hui guarantees that the winning rate can be increased many times, of course, even if it can't succeed, it won't matter, as long as it can provoke disputes and contradictions within Shu.

Jiang Wei would never easily give up the Hanzhong defense line, and it was impossible for a young man like Zhuge Zhan to replace him, but if he refused, then in the eyes of the Emperor of Shu, the situation would be different.

Zhong Hui knew that the emperor of Shu attached great importance to Prime Minister Zhuge and even loved Zhuge Zhan very much.

He is younger than himself, and he has already served as a servant of Shangshutai, and I heard that he is ready to be promoted to be the general of Wei.

This is simply outrageous, Zhong Hui can't stop his promotion, so just add fire to him, don't be a general of Wei, just step in place, wouldn't it be good to let him be a general?

Look at Wu Guo, who is also a general in his twenties, isn't the final result also very good?

We have to keep up the good work and try to surpass the person next door as soon as possible.

When the Shu Kingdom is destroyed, I have to let the world see if you can be on an equal footing with me!!

Zhong Hui looked at the people in front of him and ordered: "Since you know, then go to various places to publicize, the people of Shu will find out, and you don't need to go to Shu." ”

"The people of Shu must be more willing to believe the news they have found, and now they are panicking, knowing this news, I don't know what height to push Zhuge Zhan to."

Zhong Hui had a smile on the corner of his mouth, but his eyes were extremely fierce.

"There are many warriors in Shudi, I don't know when I will be able to meet them"

"I'm really looking forward to it."
