"With a mill, it's the same as milling rice?"

Wei Yinglong listened to Li Fei's words and fell into deep thought.

The more he thought about it, the more he felt that this idea was really genius—not impossible!

As long as the site is set up, the molten iron burned out is poured into the shallow pool, and when it is half solidified, it is directly pressed with a stone mill, and it only needs to be pressed a few times to be able to press out a thin enough iron sheet!

He immediately stood up and prepared to test it!

However, Li Fei grabbed him and said with a smile:

"Brother Wei...... You don't mind if I call you that, do you? ”

"Don't mind, Li Gongzi has something to say!"

"I'm telling you so much, naturally it's not for nothing!"

Wei Yinglong reacted at this time, but he was not a pedantic person, so he asked:

"Li Gongzi has something to say, but as long as it is within Wei's power and responsibility, he will not disappoint Li Gongzi!"

"I only hope that the pressed iron sheet can be sold more for Master Ma, and I need to make some stoves here."

"No problem," Wei Yinglong waved his hand and agreed.

He knew the blacksmith's shop, and he was just that person, and he had always insisted on it. The iron used for a month is not as good as the iron used by the craftsmen on their side for a day.

How much iron can he use?

"I use a lot!" Li Fei was overjoyed when he heard this, this thing is now an official business, just like the tobacco of later generations, at some critical times, no matter how rich you are, you can't buy more if you want to!

Wei Yinglong smiled:

"Since I have promised, I will not go back! In this way, I will write a note and give it to you, and then you can take the note and pick up the goods! ”

After speaking, he wrote a note with a brush, signed it, and handed it over.

Li Fei immediately took the slip overjoyed and solemnly put it away.

With this thing, the problem of the stove is solved.

Everything is in place, only the east wind is owed!

Wei Yinglong didn't leave Li Fei and Ma Blacksmith behind, he hurried to test the new method.

But when leaving, Wei Yinglong still said to Li Fei:

"Li Gongzi, if you have new ideas in the future, remember to inform me! Rest assured, you won't be at a loss! ”

Li Fei nodded hard.

In these years, iron represents productivity, and it seems that when you are free, you should try to recall some of the knowledge you learned in middle school, by the way, how was the blast furnace built?

The two of them walked on the way back, and the blacksmith Ma sincerely admired:

"Fei Ge'er is really not an ordinary person! That Wei Yinglong never pretends to talk to people, if the words are not speculative, he will get up and leave immediately, and he will not say more than half a word, today Fei Ge'er only has one thought, so he has a big change in attitude, it is really amazing! ”

Li Fei smiled and said: "I just talked about his concern - this kind of technical talent, the most concerned is technology, as long as you mention the key, even if you beat him and scold him, he is willing, if there is no technology, even if you coax him to lick him, he will abandon you like a piece of!"

Blacksmith Ma didn't seem to understand, but Li Fei didn't expect him to understand, but changed the topic:

"Master Ma, now that the iron sheet is available, and the number is not limited, then we have to change it!"

Blacksmith Ma didn't expect Li Fei to talk about the product immediately, with Wei Yinglong's previous attitude towards Li Fei, Blacksmith Ma couldn't help but congratulate and listen carefully.

"Before, we just talked about the stove, I was afraid that the iron sheet would not be easy to beat, so I didn't say anything else, now since there is no shortage of raw materials, then in addition to the stove, the matching chimney is also to be played!"

"Pipes?" The horse blacksmith sounded a little confused.

Li Fei said it again, the horse blacksmith seemed to understand whether he understood it or not, and seeing that he had immediately walked to Yongning Fang, Li Fei simply picked up a branch on the side of the road and drew it on the snow!

Yes, it's winter now, Chang'an City, it's already snowing!

"You see, the previous stove burned charcoal, and basically there was no flue, but charcoal gas can hurt people, so we have to design this point well, and we can't turn good things into bad things!"

Li Fei explained to the blacksmith Ma while drawing.

As soon as the blacksmith heard that it was a matter of human life, he immediately became serious.

Actually, the chimney straight is very understandable, but the important thing is where the bend is turned.

This involves cutting the iron sheet into the hole, then cutting off the excess, then rolling the rest up and closing it, and beating it together.

This is very important.

Afraid that the horse blacksmith would not understand, Li Fei directly drew three views on the snow, which made the horse blacksmith nod vigorously and said that he understood.

Li Fei was painting here, not feeling that there was one more person next to him.

Xiao Yu was standing behind Li Fei, and suddenly asked at this moment:

"Little brother, how do you know that charcoal gas can hurt people?"

Li Fei turned his head and was startled!

When did this old man appear behind him?

But then he smiled and said:

"I've seen Guogong!"

Guogong can talk to himself so kindly, that is to look up to himself.

Even if in later generations, it will be said that everyone is equal, but if a big man with a national name talks to you so kindly, will you be excited?

"Don't be so polite," Xiao Yu waved his hand and said, "I heard what honeycomb coal you are doing these days, but is there such a thing?" ”

Li Fei nodded and said:

"Coal is a thing that can be burned when it is mined from the ground, and it was called charcoal in ancient times, which itself shows its function. We are now mainly used for iron smelting, and there are too few households, and the reason is that charcoal is easy to hurt people, and coal is easy to smoke and choke. ”

Xiao Yu said with a smile:

"So, you came up with the idea of using this method of making honeycomb coal to solve this problem?"

Li Fei nodded and said:

"Yes! The problem of carbon gas can be solved through the chimney, and the problem of flue gas, after being beaten into honeycomb coal, as long as the lid is covered, this problem will be gone. And with the lid, it can also greatly increase the combustion efficiency of coal and save costs! ”

"Efficiency?" Xiao Yu was a little puzzled, "What does this mean?" ”

Li Fei was stunned for a moment, and then inadvertently said a word that has not yet spread or has not spread, he thought about it and explained:

"This efficiency, for example, is the same charcoal, and the more hot water is burned, the higher the efficiency...... That's roughly what it means. ”

Xiao Yu was the secretary of the household department, and immediately understood what Li Fei meant.

He nodded and said:

"You're a good idea, have you practiced it?"

"I've practiced, and now that's what I have at home!"

"If it is feasible, then the official coal can also be purchased from you!" Xiao Yu did not hesitate to appreciate Li Fei at all, "But this will have to wait until you make it!" ”

When Li Fei heard this, he was pleasantly surprised!

If you really want to open up the channels of official procurement, this is equivalent to a royal businessman!

In these years, there is no kind of exploitation in later generations, and the official procurement is real money, and it will not lose the merchants, which is a great thing!

Now, it's going to be developed!
