The Lantian mining area is an area that belongs to the smelting workshop.

After a day of cooling, personnel went inside for a detailed inspection, and after confirming that everything was correct, a new sponge iron was installed.

Although the improved iron-making furnace can be directly thrown into ore and smelted into molten iron.

But in that case, the efficiency was a little too low, so Liu Ponu still decided to use the original smelting method.

The ore is smelted into iron sponge in the traditional way, and then the iron sponge is placed in a new furnace for secondary processing.

The separation of the two processes can save waste to the greatest extent and improve the efficiency of the ironmaking furnace.

Otherwise, a furnace full of raw materials is added, and the final one is not even one-fifth of the molten iron, how embarrassing it is.

"Young master, the master is here, and he brought a lot of people...... Hearing that the emperor was coming, Liu Qu couldn't sit still, and hurriedly left the affairs in Lantian County and ran to the mine.

This time, the emperor came with a lot of ministers, and it is estimated that it has something to do with molten iron.

Liu Qu was also a little unsure of what the emperor's intentions were this time, and he didn't dare to ask about it.

Therefore, I can only remind Liu Ponu in advance and tell him to talk about the door and not throw out any tiger and wolf words to embarrass the emperor.

"Come on, I'm busy!" Liu Ponu was directing people to install the furnace while thinking about trying something else.

How can Liu Ponu, who is interested in scientific research, have the kung fu to take care of Liu Che?

Even if Liu Che walked to the door, he might not have time to greet him, let alone the people he brought, what does it have to do with me?

"Who's that, go next door to get some steelmaking materials, and find some steel!" Liu Ponu suddenly wanted to try to see if this thing could directly train the steel.

Although I don't have any confidence, but who hasn't done it in scientific research?

Isn't there a saying in the scientific community that research is an accident, and you never know if the things you find by accident will be more important than what you want.

Liu Ponu didn't know how to make steel, but it didn't prevent him from messing around.

Anyway, Minke told him to just throw some scrap steel into it, as for the converter thing.

Liu Ponu can only say that there is nothing to be done for the time being, the current furnace is lined with ceramic, and I really don't know if it will explode when it turns around.

You must know that except for one drain that is automatic, everything else has to be done manually.

People are standing on the top of the high-temperature furnace to add materials inside, suddenly the stove bursts, and then the whole person can't even find a single ash, do you dare to imagine that scene?

……

Liu Che's face was a little unhappy.

I ran from Chang'an in a hurry, and I didn't even have the time to drink saliva along the way, but you kid didn't even want to go out to greet him?

Looking at Liu Ponu, who was squatting under a tree and looking at the iron-making furnace and didn't know what to think, the anger in Liu Che's heart instantly dissipated a lot.

Ignoring his image as an emperor, he walked towards Liu Ponu by himself.

The three princes and nine ministers behind him naturally didn't dare to hold it up, but they also followed some distance from the emperor.

Many people are ready to watch the play in their hearts, this Liu Ponu is so unruly that he doesn't even understand the most basic etiquette.

However, the facts shocked them.

Even if the emperor walked in front of him, Liu Ponu still didn't stand up, and instead of getting angry, the emperor naturally squatted down beside Liu Ponu.

"I heard that your kid has trained molten iron?" Liu Che asked with a smile on his face.

"Hmm!"

"Why aren't you happy at all?"

"Isn't it normal to practice molten iron? What's there to be happy about? Bad old man, you shouldn't jump three feet high in excitement and go to the emperor like a fool to pretend to be forced, right? Liu Ponu smiled, deliberately pretending to be silent, and at the same time sarcastically mocked Liu Che.

'Hiss......'

Liu Ponu's words frightened the three princes and nine secretaries behind him, and they couldn't help but gasp.

What kind of wild way is this special mother?

It's okay to call the emperor a bad old man, but you dare to scold the emperor for being a fool?

"When will you kid spit out the ivory from his mouth?" Liu Che scolded angrily.

Liu Ponu thought for a while and replied seriously: "From the perspective of genetics, I suggest that you retract this sentence, otherwise I really can't ......answer this sentence."

"Why?" Liu Che was stunned, what genetics is not genetics, I haven't died yet, why did I leave it behind?

"I'm a dog, so what are you?"

"......" Liu Che looked at Liu Ponu with a confused expression.

', this Liu Ponu is really a head iron, scolding the emperor one after another, really dare to throw any tiger and wolf words out? ’

The three princes and nine princes felt that their three views had been completely subverted by the father and son, and they had never seen this scene appear in the royal family, and they didn't even dare to think about it.

This scene also made Sima Qian feel very deeply, playing and playing, who is playing with you?

He had already figured out how to describe the relationship between Liu Che and Liu Ponu after he went back.

The love between father and son is deep, the father is kind and filial to the son, not limited to form, no words or no words, I dare not talk about it, like a friend for many years......

"Where's the molten iron you practiced? Pull it out and give my bad old man a good eye-opener! Although Liu Che wanted to beat people very much, but at this time, he remembered his poor imperial prestige, so he asked forcibly.

"Pull it next door and let the blacksmiths play, these furnaces have just been added, if you want to see the molten iron, you can only wait until the evening......" Liu Ponu said casually, but he was still thinking about steelmaking in his mind.

"You can make molten iron, this is a great achievement, why can't the emperor be too bad for you last time, why do I look at you sullen?" Liu Che could see that Liu Ponu seemed to have something on his mind, but he had never seen anything that could bother him for so long.

According to the past practice, two or three sentences of kung fu this kid can be like a person, which is like today, it has always been like someone owes him money.

"Oops, old man, I really wonder how the emperor fell in love with such a superficial person as you?" A smile suddenly appeared on Liu Ponu's face, and he quipped with a sly face: "If you can make molten iron, can you make molten steel?" Let's not talk about the quality, let's just say that all the weapons in the hands of the soldiers are replaced with weapons made of steel, so what will happen on the battlefield? ”

"Steelmaking? How can it be so easy! Liu Che smiled.

It's not that he looks down on people, and it's not a joke.

Of course, everyone knows the benefits of weapons made of steel, but what is the material so easy to obtain?

He needs the blacksmith to keep beating and tempering repeatedly, and it may be an exaggeration to come a hundred times, but it is normal to temper thirty or fifty times repeatedly.

Generally speaking, an experienced old blacksmith can build a steel weapon in ten days and half a month.

And even so, only middle and senior generals above the captain level can be equipped with steel weapons in Dahan, and not everyone can equip them.

As for the ordinary soldiers, they are divided into two classes.

Most of those who fought on the front line were equipped with iron weapons, and those who were on duty at home were equipped with bronze weapons.

Even though the current iron-smelting process has been improved, the yield and quality have been improved.

But the Han Dynasty was still very reluctant to ensure that the front-line soldiers used iron weapons.

You must know that it is not a pair of weapons, but hundreds of thousands of weapons, and the iron smelted here is to be poured to make new ploughs.

"How else to say that you are pedantic and don't know how to be flexible?" Liu Ponu still unceremoniously counted down.

And today's scene really opened the eyes of the ministers, as if Empress Dowager Dou didn't scold the emperor like Liu Ponu back then, right?

The question is, why isn't the emperor angry?

Could it be that the emperor is sick?

Why did Liu Ponu scold him more and more happy?

Looking at the smile on Liu Che's face, Liu Ponu was also completely speechless.

There is really a kind of boy who has what kind of boy, and the reason for his cheekiness has finally been found.

"The molten iron has been trained, why can't we try to see if we can train the molten steel? What if it does? Liu Ponu looked at Liu Che with disdain, then pointed to the pipes connected above the blast furnace and continued: "See those pipes? Originally, it was used to blow air in the furnace, using a bellows, not to mention the small wind, and people need to keep rotating, and the people who were replaced were tired and couldn't scream when they lay on the ground, and they were covered with stinky sweat. ”

"I can't bear to see it, so I want to find a way to replace them, this back and forth, don't you just make a water drain, now you don't need someone to pull the bellows, the wind blowing out is still bigger than before, and there is no need for people to rotate, it can keep sending gas to the furnace all the time, it used to take two days to refine a furnace, now it only takes one day to be enough."

It didn't seem to be too enjoyable, Liu Ponu didn't hide his contempt, and then said: "Don't think it's impossible when you encounter something, you can't even do it, how do you know that he can't do it?" ”

Liu Che nodded helplessly.

There are still three princes and nine kings standing behind him, you kid is shameless, am I shameless?

Although what you kid said is very reasonable, I am the emperor.

Don't you really have a little bit of a count in your kid's heart?

Is it true that you don't save any face for me?

"I know, you told me about this, in the end, isn't it because you're too lazy......" Liu Che suddenly remembered what Liu Ponu said before, people who like to be lazy, he will try his best to complete his task while being lazy, and now Liu Che feels that it is very appropriate and perfect to use this sentence to fight back against Liu Ponu.

"Lazy or not, go back and talk ......" Liu Ponu lazily quibbled with Liu Che in this regard, his little head turned around, the corners of his mouth rose slightly, and he said shyly:

"Bad old man, it's very expensive to do research, the money left behind is almost bottoming out, and now the molten iron is also out, you have a good relationship with the emperor, while the emperor is happy now, you go and fool the emperor to get me some money, let me tell you, I've already tied up with Yizhou, when the time comes, let's go over and shout, and the people can surround the government overnight......"

There was news from Hanzhong that the people in the county were very motivated, and the timber output was amazing, and when the farming was completed, they would start arranging a batch to be sent over first.

Although Liu Ponu is not short of money, the more money the better.

Trading with Hanzhong, only by handing over the money and delivering the goods with one hand can he gain the hearts of the people, Liu Ponu didn't want to wait until someone sent the timber over, he smiled, and then told them to pay on credit......

So, it's reasonable to take this opportunity to have more money as a backup, right?

Isn't this much better than letting Liu Che spoil it?
