75 of the world's most advanced

Early the next morning, Emperor Chongzhen went to see Concubine Tian and asked her to match it with appropriate jewelry based on the look of the dress. He chose several sets in total, then took photos and sent them to Liu Weichao.

Then, he was not interested in political affairs and waited for Liu Weichao to send him a message.

After he sent the message for a while, the phone finally started to buzz. It was Liu Weichao who had replied and sent him three documents.

When Emperor Chongzhen saw it, he was immediately overjoyed. He quickly opened it to look at it, only to find out what kind of mathematics, physics and chemistry it was.

What is this?

Emperor Chongzhen was stunned for a moment before he came back to his senses. This was probably what Liu Weichao said was scientific!

So, he immediately looked at it, first to see what chemistry it was.

Because Emperor Chongzhen still remembered that he didn’t understand the content of this chemistry at all, so it was a pity that he couldn’t create such powerful gunpowder!

After reading patiently for a while, Emperor Chongzhen couldn't help but rub his forehead, feeling that it was a bit difficult to learn!

Forget it, let’s look at the others first!

So, he clicked on physics again and started reading.

This is slightly better than chemistry. However, it is only slightly better.

After a while, Emperor Chongzhen patted his forehead again, and with a little reluctance, he finally closed the document.

Finally, he clicked on mathematics and found that it was very simple at the beginning, just arithmetic!

Emperor Chongzhen finally found some confidence, and then he started to read.

As a result, he looked at it, and at the end, he closed the mathematical document again.

"It's not that I don't understand, it's just that I don't have time to learn!" Emperor Chongzhen said to himself, and then he became a little irritable. To be precise, he was impatient.

He stood up, walked back and forth a few times, and looked at the mobile phone on the desk. There was no other movement, which made him even more impatient.

At this time, what Emperor Chongzhen is looking forward to is the information Liu Weichao mentioned last night. Those are what he needs most urgently now.

He was irritated when suddenly his phone vibrated and it was Liu Weichao requesting video communication.

As soon as Emperor Chongzhen saw it, he rushed to the imperial court, quickly picked up the phone, and quickly clicked the "Connect" button.

Suddenly, Liu Weichao appeared on the phone, smiled and said to Emperor Chongzhen: "I found out that after I checked the information, I realized that things were far from as simple as I thought. I'd better tell you verbally first, and then give the information to you

I’ll send it to you. If you still don’t understand anything, just contact me again!”

Upon hearing this, Emperor Chongzhen couldn't help but breathed a sigh of relief.

After waiting for so long, what he was most afraid of was that Liu Weichao was busy with other things and did not take his matter to heart, or that he did not deal with it first!

Now it sounds like Liu Weichao attaches great importance to this matter, but the complexity of the matter is beyond his expectation.

Thinking of this, Emperor Chongzhen replied with a little relief, and then a little worry that it would be too difficult: "Okay, I will listen to you!"

After hearing this, Liu Weichao said to him: "In the era of industrialization, the most basic thing is steel. When you fight, the most important thing is actually steel. If your steel is good enough, then your armor, weapons, muskets, etc.,

The quality of everything that uses steel is better than that of the enemy, and your winning rate will be greatly improved."

Having said this, he paused and then added: "There are many steel tools used in people's livelihood. If good steel is available and the price can be reduced, it will be of great help to both the military and people's livelihood. Therefore,

I’ll solve the steel problem for you first!”

Upon hearing this, Emperor Chongzhen couldn't help but be overjoyed, nodded quickly and said: "Okay, okay, I listen to you!"

Liu Weichao was not in a hurry to get to the point, but said to him: "Actually, the steel smelting in the Ming Dynasty was already the most advanced in the world. It was even better than that in the Western Yi Dynasty at this time!"

At this point, he smiled and then said: "I checked and found that the steel smelting process in the book "Tiangong Kaiwu" has reached the stage of large-scale, mass production, and continuous production of raw and wrought iron.

.This is to connect the iron-making furnace and the iron-frying furnace in series, allowing the liquid pig iron smelted from the iron-making furnace to flow into the iron-frying furnace, and stir it with a willow stick to oxidize the carbon in the liquid pig iron and mature iron. This kind of continuous production

The process has begun to take shape in the systematic thinking of combined production, which not only improves production efficiency but also reduces energy consumption. This is what I meant by the automated assembly line operations I mentioned to you before."

"What is "Tiangong Kaiwu"?" Emperor Chongzhen was a little puzzled when he heard it. He thought about it in his mind, as if he had never seen this book at all!

When Liu Weichao heard this, he was a little dumbfounded and immediately explained: "What I told you is the book written by Song Yingxing that I recommended to you. The contents of his book are all what he saw along the way when he went to Beijing to take the exam.

Smell. The technology inside was definitely available in your time."

"Oh!" When Emperor Chongzhen heard this, he finally remembered that Liu Weichao had indeed said this, and nodded with a little pride.

There was nothing he could do. He had always felt that he was being crushed by Liu Weichao. But now, he finally had something that Liu Weichao praised.

"The iron smelting recorded in "Tiangong Kaiwu" was invented by the Western Yi people a hundred years later." Liu Weichao introduced it to Emperor Chongzhen in detail, "The difference is that the Western Yi people usually use wrought iron.

Stirring rods or steel rods are used to burn off the carbon in the pig iron, and finally obtain low-carbon wrought iron. In the Ming Dynasty, willow sticks were used to stir, and the willow sticks were gradually burned while stirring, which allowed carbon to be mixed into the pig iron.

In other words, reduce the speed of decarbonization of pig iron."

After a pause, he said with a little regret: "Unfortunately, although the Xiyi people invented it late, they continued to develop for more than a hundred years; while here after the Jianlu rule, not only did we not have many inventions within a few hundred years,

Development, on the contrary, regressed significantly. Then..."

At this point, Liu Weichao thought of something and quickly stopped the topic and said: "Forget it, I won't talk about the rest. What I want to tell you now is to improve the smelting process so that you can produce high-quality steel at a lower price."

It can also drop significantly!”

Emperor Chongzhen was listening, still thinking, why is there carbon in steel? Then he heard Liu Weichao's last words, and suddenly a trace of contempt emerged in his heart. Jianlu was a barbarian, how could he have any knowledge!

But when he came back to his senses, he was stunned again. Because he suddenly thought that he was the barbarian he despised, and he was beaten to the point of almost subjugating the country!

Emperor Chongzhen's face looked unnatural for a moment, and he quickly put aside this idea, and then quickly said to Liu Weichao: "I am all ears!"

If high-quality steel can really be produced and the price can be significantly reduced, it will definitely be something worth looking forward to.
