By the time Ru Taisu returned to the noon gate after asking for instructions, Li Wei had already disappeared, and the old man was so angry that he jumped to his feet.

Ministry of Works, Sun Jian covered his ass and came to Zhao Jun.

As soon as Zhao Jun saw him like this, his face sank: "That Li Wei beat you again?" ”

Sun Jian made a bitter face and nodded: "Yes!" ”

"Hmph, this traitor is really lawless, tomorrow I will impeach him again to His Majesty!"

"Don't don't, don't ......" Sun Jian hurriedly dissuaded with a bitter face: "The lower officials are at fault, and Lord Li should teach him a lesson, so Lord Zhao should not tell His Majesty again." ”

"Huh?" Zhao Jun frowned and said dissatisfiedly: "Are you afraid of being beaten by him?" ”

"This ......, the lower official thanked Lord Zhao for his kindness, but he really doesn't need it."

Sun Jian is really afraid of that Li Wei, he doesn't want any face, he is even more arrogant than the current emperor.

"Hmph, can't stand this pain? What a rubbish! ! ”

Zhao Jun was very dissatisfied, didn't he just beat him twice, and he was subdued? What a non-compromising thing!

It didn't hit you, of course you don't have a backache when you stand and talk. Sun Jian didn't say anything, but muttered in his heart.

"Hey, thank you, Lord Zhao, the next official has retired."

After speaking, Sun Jian covered his ass and retreated.

Zhao Jun looked at Sun Jian's cowardice, and there was a fire in his heart, originally Sun Jian and these people were all under his control, but as soon as Li Wei came, he took more than half of it, and his current authority as a left attendant is not even as good as Li Wei, the new right attendant, how can he bear it!

Li Wei returned to the Ministry of Industry and began to do business, the weapons and equipment that Lao Zhu wanted had to be made quickly, otherwise if he couldn't get it out in the end, I don't know how Lao Zhu would fix him.

instructed Guan Ziming and Jiang Shouqing to take care of other departments, so he called Sun Jian, who was still covering his buttocks, and went to the Ordnance Bureau with a few errand officers.

Xu Yong and Lu Ti, ambassadors of the Ordnance Bureau, came to greet them, and Li Wei was perfunctory, urging them to gather craftsmen and start transforming the Ordnance Bureau.

First of all, you have to build a coke oven, this principle is also very simple, Li Wei gathered the craftsmen, took out the sketch and explained it to them in detail.

Sun Jian and Xu Yong were confused and couldn't understand anything, but it was the deputy envoy Lu Ti who heard the doorway and occasionally asked Li Wei for advice.

"My lord, why are we refining this...... This coke? ”

Although Lu Ti understood what Li Wei meant, he didn't understand why he was refining this thing, it sounded like a superfluous move, didn't the coal burn the same?

Li Wei patiently explained: "The temperature of coal burning is not enough, and the reason why your blast furnace cannot make steel is not enough is one of the main reasons. ”

"What, my lord means, as long as the temperature is raised, it is directly smelted steel?"

"No, but high temperature is one of the main steps, and after the molten iron is smelted at high temperature, it must be blown or stirred, so that the residual carbon elements in it can fully react with the oxygen in the air to further reduce the carbon content."

"What does carbon content mean?"

"Carbon content is the main indicator that distinguishes steel from iron, and the so-called steel is actually an iron-carbon alloy with a carbon content between 0.02% and 2.11%."

He researched this when he was developing a new product for the dog boss.

"What is oxygen? Isn't the air empty, how can there be something? ”

“……”

Luti's eyes widened, and while thinking and listening to Li Wei's description, he felt as if he had seen a new world.

He is different from Xu Yong and Sun Jian, he is a craftsman with craftsman skills, after all, officials can't all point fingers, there must always be an officer.

The last time Li Wei came to inspect, he was only a big official who came to pretend, but at this time, with Li Wei's narration, he realized that this squire is different from other officials who can only point fingers, and he is a truly talented person.

Li Wei tried his best to explain the principle to these craftsmen, hoping that they could understand the reason for doing this, understand the reason to do it, and do it without knowing anything, there is still a big difference, in case there is a problem, or know how to find a solution.

However, he soon found that his idea was a little naïve, although these craftsmen did not have to say the craft, but they told them the basic principle, that is, to play the piano to the cow, just like Luti, the composition of the air could not be understood for a long time, in their consciousness the air is air, nothing.

Not only that, but many times there will be conflicts between scientific theories and their inherent cognition, you talk to them about matter, they talk to you about the attributes of the five elements, you talk to them about chemistry, they talk to you about the changes of the five elements, and even metaphysics and religion, which is messy, which makes Li Wei big for a while.

After a long time, he found that it was too difficult, and it was better to find a group of children to start teaching from scratch.

Well? That's a good idea.

Children are a blank slate, there is no inherent cognitive impairment, they will listen to what you teach, starting from the baby, it is a good way to promote science and technology.

It takes years or even more than ten years.

"Just do as I say."

Li Wei gave up explaining the principle to them and directly talked about the method.

"Just make a coke oven, you must isolate the air, by the way, the coal must be washed first, remove dust and impurities, select high-quality coal, and then crush it to make a briquette, and iron ore must also be washed first......

Coking is one of the important steps in industrialization, not only to provide coke that can produce higher temperatures, but also to by-products such as coal tar and gas, which can be distilled to produce other industrial products, such as asphalt, pesticides, etc., are all good things.

Of course, he can't make the latter for the time being, but he has to keep them and study them slowly in the future.

Industrial development is interlocking, and when one industry rises, it will drive other industries.

After arranging the coking matter, Li Wei talked about the upgrading of the blast furnace, the transformation of the waterwheel, and the preparation of generator materials.

The craftsmen listened carefully to Li Wei's explanation, although they didn't understand, but they just listened to the arrangement of Lord Shilang when they worked.

These jobs are all big projects, and Li Wei can only let them take their time.

Sun Jian and Xu Yong were basically playing soy sauce throughout the whole process, which made Li Wei very dissatisfied, Xue Xiang had his squire to share his worries, and he was leisurely all day long, while his own subordinates had no use for farts one by one, so they could only do it themselves!

After a busy day, he finally returned to the Ministry of Industry, and just as Li Wei was about to leave after greeting Xue Xiang, someone came to him again.

"Little Dezi, I haven't seen you for a long time."

Xiao Dezi smiled, it's been a long time, and the author has almost forgotten me.

"Lord Li, Your Majesty has summoned you to the palace."

"Ugh."

Li Wei didn't have to think about it to know, it must be that the writing business is not over, and Lao Zhu is going to trouble him again.

I've been busy for most of the day, and I'm already very tired and have to deal with the leader, which is really annoying!

Helpless, Li Wei could only follow Xiao Dezi into the palace.

In the Qianqing Palace, Xiao Dezi took Li Wei to Zhu Yuanzhang and retired by himself.

Zhu Biao was reporting government affairs to Zhu Yuanzhang, and stopped first when he saw him coming.

Li Wei lazily saluted: "Meet Your Majesty, I have met His Royal Highness the Prince, Your Majesty, what do you have to tell me?" ”

Zhu Biao was depressed and nodded casually.

And Zhu Yuanzhang stared at him with an ugly face: "Do you think you are the smartest?" ”

"What do you mean?"

"Let's arrange for you to write a word, you have repeatedly misinterpreted our will, is it itchy?"

“……”

Li Wei pursed his lips and objected to Lao Zhu's stinky problem of using violence to solve problems at every turn.

But the opposition is obviously ineffective, fortunately, he has already thought of countermeasures on the way here, and he should be able to escape today's fight.
