Farmer of Shu Han

In fact, before the industrial revolution, the development of the global metallurgical industry was limited by the temperature of fuel combustion.

Within the allowable range, the higher the controllable temperature, the easier it is to smelt iron and steel.

The key to Feng Yong's assurance that good iron can be smelted with charcoal is that he knows that there is a way to increase the temperature of charcoal when it is burned in the forge.

That is to add a blower to the iron furnace.

I remember that when the history book talked about the history of metallurgy in China, it said that the handicraft industry in the Song Dynasty was particularly developed. What impressed Feng Yong most was that there was an illustration on that page, which showed a person pushing and pulling a blower.

The explanation in the book is that the blower can increase the temperature inside the furnace.

When working on coke, Feng Yong wanted to build a better blower, but unfortunately, the time was too tight, and he had to design, test, and even improve the furnace to see how to match the blower...

He is not an almighty superman, how could he take care of it?

In the end, a few small test machines were built.

So this is why he can only create thirty sets of armor - the efficiency is really too low.

Anyway, I didn't intend to make money from iron smelting. This method, I handed it over as soon as I handed it over, and there was no loss.

As far as the current requirements of the prime minister of the Han Dynasty are concerned, he only needs to produce good iron. As for the production efficiency, there are not many requirements for the time being.

Solve the problem of whether or not first, and then think of the problem of how much.

It is a way of thinking with Chinese characteristics.

Feng Tubie wanted to be lazy with peace of mind.

As for the day when the prime minister of the Han Dynasty suddenly discovered that charcoal is too restrictive for iron smelting, if he wanted to produce refined iron better and faster, his eyes would naturally fall on coal—at that time, I would earn money by selling coal and coke. Big hair!

The method of smelting refined iron is handed over to the country... Well, the imperial court, you are always embarrassed to rob my coal mine again, right?

If you dare to snatch it, I will recruit the queen to join the gang again!

If it still doesn't work, tell the old demon Zhuge that there is coal all over the ground in Nanxiang, and as long as you are willing to put in the effort to find it, you can definitely find it.

Nanxiang is so big that it includes two counties in later generations.

With the current level of technology and this amount of manpower, it will take decades or even hundreds of years to dig, and I am afraid that they will not be able to finish digging.

Decades later, either the big man is gone, or I am gone, who can control the affairs behind?

It would be even better if the ideal of the prime minister of the Han Dynasty to return to the old capital can really be realized-if it is true to return to the old capital, who would care about the coal in Hanzhong? Guanzhong is all over the world!

"Ordinary iron stone, how can you refine refined iron with charcoal?"

Seeing that Feng Yong was willing to tell the secret technique of his master, Pu Yuan asked impatiently.

"Oh, that's simple. To smelt refined iron, one must either find high-quality iron ore, or increase the temperature in the iron furnace... um, um, find a way to make the fire in the furnace even hotter."

It is often said that China has a vast land and abundant resources, and is rich in mineral resources, but there is a sentence that is often ignored.

That is, there are many lean ores, few rich ores, and many associated ores, which have brought many difficulties to smelting.

So it is very difficult to find high-quality iron ore.

China began to enter the Iron Age in the Spring and Autumn Period and the Warring States Period, but it would take the Han Dynasty to say that iron ware completely replaced bronze ware.

It is a pity that due to the limitation of the temperature of the forge, the improvement rate of smelting technology has been very slow.

Therefore, the current level of iron smelting can only be regarded as initial or even primitive. It is not too difficult for Feng Yong to improve the iron smelting furnace.

The difficulty lies in how to produce high-quality iron in large quantities.

It is not difficult to add a blower, but the difficulty lies in how to add a large blower to improve production efficiency.

"How to burn it?"

When Pu Yuan heard this, he finally believed in his heart that Feng Yong really knew how to smelt iron.

Even if you want to smelt good iron, you can only find a good iron mine, and you must also pay attention to the quality of the water for quenching the iron, but how to make the fire in the furnace burn hotter is unknown.

"I can't say it out of words, I'll draw a picture for Madam later."

The stingy Feng Tubie still remembered what Pu Yuan accused him just now, but he deliberately didn't tell him.

Most importantly, Feng Yong also thought that since Huang Yueying had studied the book "Lu Ban Jing", then the handwork should not be bad. It is said that all the inventions of Zhuge old demon in history were inseparable from Huang Yueying, and now it seems that it may not be true.

Send this blower to her, what if she can improve this thing into what she wants?

Isn't that meant to be fun?

This woman... To be honest, she is really a top-notch woman.

Zhuge old demon's luck... can't be said.

Feng Tubie was thinking wildly, only to see Huang Yueying turned her head away, nodded slightly to Zhuge Liang, and then turned to look at him lovingly, with joy at the same time.

"Okay, then I will wait for you to draw it. It has been delayed for a long time, then I will not bother the prime minister to ask you any more questions."

With that said, he got up and walked out.

Seeing this, Pu Yuan had no choice but to reluctantly say to Feng Yong, "Feng Langjun, after talking with Kong Ming later, don't forget about it."

Only then did Huang Yueying and Huang Yueying walk out one after the other.

Looking at the expression of satisfaction under the plain face of Zhuge Old Demon who was sitting above, Feng Yong suddenly understood, this... It seems that three people plotted against him together?

Just for the secret of armor and weapons made of fine iron?

As for what?

"See it?"

Zhuge Liang was the number one person under the emperor of the Han Dynasty, and Feng Yong's change of mind naturally couldn't escape his eyes.

It's just that the prime minister of the Han Dynasty is magnanimous after all, and after seeing the two of them going out, he admitted openly, "I won't hide it from you, ever since Pu Yifan heard that you have armor weapons made of fine iron, I am very excited. It's curiosity."

He said with a sigh, "All these years he was entrusted by me to find iron smelting places that can make good weapons. It's a pity that he has searched all over the land of Shu, but there is no place where he can be with the late emperor again. Compared with the Jinniu Mountain at that time."

"I thought this was the end of the matter, but I didn't expect God Bless the Great to see this kind of refined iron in your hands, so I had to ask you to test it out."

"Thieves Cao are very powerful, occupying the confidant of the Central Plains, which cannot be compared with the big Han who is partial to one side. Therefore, if we want to revive the Han Dynasty, we have to resort to some extraordinary measures."

It's understandable, and I also know that for this, you invented a lot of things later.

Feng Yong muttered in his heart.

"In the past two years, I have taken something from your hands, and I will remember it in my heart. Whether you complain or hate, it is all because of me, but there are some things that I have to do."

"I just hope you can understand a thing or two because of the fact that the big man is so weak."

Seeing Zhuge Liang who was sitting on top saying these words calmly, and looking at his face, it seemed that he was a little older than the previous two years.

I don't know if it's because the light is too dark to see clearly, but Feng Yong always feels that his temples are a little gray.

With a soft heart, Feng Yong said, "Yong is a man of the people, and he has to do his best for the man, so the prime minister doesn't have to worry about it. After all, the prime minister has taken a lot of things in the past two years, but It also gave a lot of things, enough."

Although the old monster Zhuge kept shouting, Feng Yong still knew that the prime minister of the Han Dynasty was indulgent and tolerant enough for him.

And secretly gave himself a lot of help.

Besides, rejuvenating the Han Dynasty is almost all his beliefs for the rest of his life.

For the sake of faith, he can even give up his own property and life, what else can you do to him?

Even the emperor has to shrink back, how can the soil turtle turn over under his hands?

So Feng Yong never had too many extravagant hopes.

Zhuge Liangliang nodded, "If you say it's enough, then I'll take it as enough. Anyway, the big man can't give you more now. If in the future..."
