Iron ore was mined one after another.

The first batch of iron ore was transported back to Wanghai City, but the next iron ore was not left to be done, An Zhongzhi arranged nearly 100 craftsmen, rushed to Linjiang City, stationed near the mine, and directly refined the mined iron ore.

This efficiency is self-evident and exceptionally high, as it saves time in transporting iron ore, and at the same time, one benefit is also revealed, which is the slag left over after the iron ore is smelted.

Now the two cities of Wanghai and Linjiang are desperately building roads, the foundation of the road is very important, now with these slag, only need to be dumped on the road to be paved, and then tamped, than simply smooth the dirt road much faster.

"With slag, the speed of paving the road has increased by at least half." After looking at the speed of road construction for a day, Lin Bei said with certainty.

Paving, paving, paving, this stone road from Wanghai City to Jiuzhen County extends forward at a rapid speed, this is the main road, like a big tree, and the rest of the path is a tree branch, extending from the big tree, forming a dense road network between Wanghai and Jiuzhen County.

The results are quite rich, but unfortunately, there is still a lack of something that can run on this road, that is, the steam carriage that Lin Bei never forgets, without the steam carriage, the role of this road cannot be reflected to the greatest extent at all.

"Blind Lee hasn't been out yet?" This is the outside of the blind Li blacksmith's shop, and Lin Bei and An Zhong are standing in the shade.

"Yes, my lord, only a few of the apprentices of the blind Li came out from time to time to take a look and bring some food to the blind Li, they said that the blind Li was a little crazy, by the way, an apprentice was scolded by the blind Li a few days ago."

"It seems that there is not much progress, otherwise the blind man Li would not be so angry. It's hard for him. Lin Bei sighed.

"My lord, what is the method of filling steel to the bottom? I've heard those blacksmiths say this all these days, isn't a hundred steels just steel? An Zhongzhi asked curiously.

"Although the names of 100 steels and 1000 steels are steel, they are actually only iron in essence, and the method of filling steel is the real steel. The biggest difference between steel and iron is oh. Lin Bei's body shook suddenly, and he finally remembered that the biggest difference between steel and iron should be divided by the amount of carbon, right? How much? Lin Bei really couldn't remember.

"Carbon content? The method of filling steel with carbon content" Lin Bei muttered these two words, if he had no understanding in his heart, but it was almost there, as if there was a film across it.

"What's wrong, sir?"

Lin Bei had an answer in his heart that was about to come out, and at this moment, there was a loud cry from the blacksmith shop, which was the voice of the blind man Li: "The dragon god blesses." The method of filling steel is done, it is done"

Then the door slammed open, and the blind man Li Li ran out of the house, this guy should have not taken a bath for a long time, bare-chested, and his body was all black, and it was estimated that Hanako was cleaner than him.

The ecstatic blind man Li Ben came out and saw Lin Bei. was stunned at first, and then ran directly in front of Lin Bei. Dancing hand and said: "My lord, I can fill the method of steel, my lord, the steel is out, my lord, I succeeded"

Lin Bei watched the blind man Li jumping around there. He was also very happy in his heart, but now that he was doing well, he said, "I know, you go wash up first." ”

was cooled down by Lin Bei like this, and the blind man Li slowly calmed down. looked at his body, and his black face was a little red: "The adult forgives the sin, let the villain go and come." ”

Seeing the blind man Li stepping over the house, Lin Bei suddenly asked, "This method of filling steel is to add a certain proportion of charcoal to the iron?" ”

The blind man Li turned around suddenly, because he turned too fast, he almost fell, and his one eye opened so wide: "My lord, how are you, you knew it before?" ”

"No, no, no, I still suddenly knew just now, let's go wash up first, I have to give you a big credit this time."

Just now, Lin Bei finally linked the carbon content with the method of filling steel, and the word "irrigation" means adding something to it, what can be poured to make iron into steel? The difference between iron and steel is only in the difference in carbon content, and when the two are connected, it is naturally carbon filled, and a certain proportion of carbon is poured into the iron, and the molecular structure is changed, and it becomes steel.

But it's easy to say, it's definitely difficult to do, it must be fully integrated with carbon molecules and iron molecules, Lin Bei's vision is the height of later generations, surpassing the current people countless times, the blind man Li naturally does not have this kind of vision, it is indeed not easy to make steel, but think about the blind Li research day and night, it is obviously not a fluke to succeed,

The blind man Li soon returned, he probably just wiped his body, and as soon as he reached the door, he asked urgently: "My lord, how do you know this method of filling steel?" ”

"What's wrong?" Lin Bei smiled: "Do you still want to hide this method of filling steel from me?" ”

The blind man Li hurriedly shook his head: "Naturally not, it's just that the villain thinks it, thinks it"

The blind man Li was a little awkward, because the method of filling steel was studied by him after working hard for many days, and he thought it was unique, but Lin Bei knew it, and it was difficult for the blind Li not to suspect that Lin Bei had known the method of filling steel for a long time, but this adult didn't say it.

"The adult already knows the steel filling method, but he doesn't tell me to wait, but asks me to wait day and night to think hard, the adult is really" The blind man Li complained a little in his heart about Lin Bei.

Lin Bei saw the unease of the blind man Li, so he smiled and said: "Don't think too much, I didn't know the method of filling steel a quarter of an hour ago, I only knew about steel, but Zhongzhi asked me a question, and asked me what is the biggest difference between steel and iron, and I remembered." ”

"My lord, what's the biggest difference between the two?" The blind man Li was also very curious, although he got the steel out, he still did not understand the molecular principle in it.

"The difference in carbon content is the biggest difference between steel and iron, iron has a low carbon content and steel has a high carbon content."

An Zhongzhi frowned: "My lord, this doesn't seem to be any different, right?" It's like a bowl of porridge, adding some rice to it is porridge, and adding more rice is still porridge, but one is thick porridge and the other is thin porridge. ”

"The difference is big, thin porridge can only be drunk as water, but thick porridge can be eaten as rice, one is rice and the other is water."

Well, An Zhongzhi and the blind Li are both black lines, and for the poor, thin porridge and thick porridge are life-saving meals

Lin Bei was just joking, because he couldn't explain the molecular structure to these two people. At this time, the identity of the dragon god was easy, he didn't want to answer, An Zhongzhi and the blind Li could only stare dryly.

"Alright, don't talk about it, blind Lee. Take that steel out and show me. Lin Bei got down to business.

The blind man Li personally entered the house, then came out and raised his left hand: "My lord, this is iron." Then he raised his right hand, "This is the new steel." ”

In fact, the difference between iron and steel is really not big, many people can't tell the difference between the two at all, and Lin Bei can't tell the difference, but it doesn't matter. It would be good for the craftsman to know: "How is this steel better than iron?" ”

The blind man Li said proudly: "It is harder than iron, and it is definitely enough to make boilers, please look at it." ”

Iron and steel are strips, the blind man Li first held the iron, and then pulled it violently, the iron began to bend, and the blind man said with difficulty: "My lord, iron is like this." It's actually a little soft. ”

"What about steel?" An Zhong asked directly.

The blind man Li picked up the steel bar and pulled it with the same force. The muscles on the arm flare up, and the steel bar only slightly concave to the sides and then stopped moving, and after letting go, it rebounded back to its original state, this way of watching even An Zhongzhi can understand: "It's really strong." ”

Lin Bei was also quite satisfied, this steel can be regarded as invented: "Okay." Well done, in this way, the steam carriage is hopeful, Blacksmith Li, wait for the carriage to be built. You should take credit. ”

"Master Xie." The blind man Li Xi said, his eyes rolled, he thought about one more thing, and shouted into the house: "Niu Er, come out." ”

A Han Zhuang ran out of the house and knelt down and kowtowed to Lin Bei, Lin Bei wondered: "This is?" ”

The blind man Li touched his head: "My lord, in fact, the villain can make steel, thanks to this disciple who is not a weapon." ”

"Oh?" Lin Bei looked at this Niu Er with great interest, but An Zhongzhi shouted: "Blind Li, you won't say that this Niu Er gave you an idea, right?" This kid doesn't have a very flexible brain, and he's stupid. ”

"Zhongzhi, do you know Niu Er?"

"Of course I know, our village." An Zhong said with a straight smile.

The blind man Li told the matter again, and heard that it turned out that Niu Er made a mistake and got the charcoal into the molten iron, and the blind Li because the iron smelted at that time was different, so he had today's steel, Lin Bei really felt wonderful, but think about it, aren't many inventions and creations due to various accidental events?

"Then you can't blame this Niu Er too much." Lin Bei said with a smile.

"Adult, the villain naturally knows that this Niu Er is usually diligent, and maybe he can inherit my craftsmanship." The blind Li is quite optimistic about Niu Er.

After talking for a while, Lin Bei said to the blind man Li: "Now that this steel has been made, then you can make a boiler according to the carpenter's needs, and I want to see the steam carriage made as much as possible." ”

"No."

Because of Lin Bei's attention, the steam carriage is already the hottest word in Wanghai City, even if they are not craftsmen, they all know that there is only one difficulty left in the steam carriage now, that is, the need for better quality iron, the blind Li is also pinned on by the people of Wanghai City, and now he has finally created something called steel, which is stronger than iron, so that the steam carriage can be built.

The news soon spread throughout the city, and all the idle people flocked to the blacksmith shop of the blind man, and when they saw that Lord Ryujin was also here, these people no longer had any doubts, and they all craned their necks to look into the blacksmith shop, as if flowers could grow inside.

"This is our grand event in Wanghai City." Bian Ji also arrived, twisting his beard and smiling.

"We'll have to build a steam wagon." Lin Bei still didn't dare to be too optimistic.

The wood had already entered the blacksmith's shop, and he discussed with the blind man Li how to cast the boiler, and it took half a day for the blind man Li to build a boiler like a barrel.

The sergeants carried the boiler out of the city, and the carpenters were already waiting there, and they were all hands and feet to install the boiler on a carriage, which was an enlarged version of the miniature carriage that the wood began to show Lin Bei.

The carriage is two zhang long and half a zhang wide, and the wheels are naturally crawler-type.

"The first steam engine in history has been formed." Lin Bei looked at the movements of the craftsmen, and felt a full sense of pride, and after magnifying it, Lin Bei could see the structure of the steam engine more clearly, "This should be regarded as a reciprocating steam engine, right?" The history is strikingly similar. ”

The charcoal fire in the stove became more and more vigorous, and the water in the boiler began to boil, and the craftsman listened, "The water is boiling." ”

"How's the boiler?"

"Nothing out of the ordinary."

"Wait, it shouldn't explode, right?"

"The boiler blew up the last time the water was boiled, and this time the steel boiler is really better."

"Great, wood, what do you see? Is it possible to open the stopper? ”

"Wait a minute." Wood was also nervous on his face, and even put his ears on the boiler a little, so hot that he quickly shrank his head.

There was already a snorting sound in the boiler, on the contrary, the tens of thousands of Wanghai people around didn't even make a sound, and all eyes were fixed on the boiler.

The wood unscrewed the stopper, and with a long thud, the parts of the steam engine moved, and the car shook and began to move slowly.

"It's moving, it's really moving."

"Sure enough, it moved."

"Was it a success?"

"Nonsense, it must have been a success, the cars are running."

"Wow, it's not slow, it's like you're kicking your legs."

"It's amazing, I can really run."

Mu Tou watched the car move forward, turned around and knelt down towards Lin Bei, "My lord, I am fortunate not to be dishonored, the steam carriage has been completed!" ”

Lin Bei looked up to the sky and smiled, "Haha, good!" Very good!! ”

"Long live the adults." The people of Wanghai City sent an earth-shattering cheer. (To be continued......)
