Chapter 840 This is a leap of one hundred and thirty-three times! How many million elites do gods have in full armor?

Seeing Ying Zheng’s resolute attitude, Ying Chengxuan was not angry with Ying Zheng.

He reached out and picked up an iron hammer from the table. Ying Chengxuan handed the hammer to Ying Zheng and said, "Evaluate one or two?"

Ying Zheng was puzzled, but his hand I have taken over this stick which is still warm.

First tap lightly with the back of your fingers to listen to the sound, then hold both sides of the hammer with both hands, twist it hard, and finally put the hammer on the table, draw the sword out of its sheath and chop with all your strength. Down.

"Dang~~~"

The sound of gold and iron clashing exploded. The hammer that had just come out didn't even touch the ground once, but Ying Zheng had cut a gash the size of his fingertip!

Picked up the hammer again, and after carefully observing the cross section and texture, Ying Zheng gave his evaluation: "This hammer is about ten times forged."

"Brother Nai Is that what you said correct?"

Ying Zheng had a rather confident smile on his face.

The reason why Ying Zheng made it clear that he liked swords was to increase the enthusiasm of the metallurgical industry and use the power of all parties to vigorously promote the development of Daqin's metallurgical industry.

Because Ying Zheng knows that only a sharp sword and strong armor can help Ying Zheng better unify the world!

However, Ying Chengyu sighed softly: "Is it just the level of ten forgings?"

The smile on Ying Zheng's face slowly dissipated, and he was even more confused: "This Brother Wang gave this hammer to Brother Nai.”

“Brother Wang, don’t you know how many times you have forged this hammer?”

Ying Chengyu did not respond to Ying Zheng, but pointed to the blast furnace beside him and said: "This iron ingot is cast directly from the molten iron from this blast furnace."

"How to forge it?"
 Looking at the broken iron head in Ying Zheng's hand, Ying Chengyu frowned and said: "Even if hematite is used, the directly cast finished product can still only reach the level of ten forgings."

" It's enough for agricultural tools, but it's far from enough for weapons and armor!"

"If you want to expand production in one step, you still need to build an open-hearth furnace."

"But this thing is so difficult to do!"

Being able to improve the blast furnace, produce coke, extract gas, and complete the early stage of the coal-steel complex has exhausted Ying Chengyu's brain cells.

But Ying Chengyu had never seen a Thomas converter or an open-hearth furnace in his previous life. He only knew their principles. He also needed to combine the principles with today's Daqin industrial base for design and manufacturing, and he also needed to improve the industry in the upstream industrial chain. level.

As for the oxygen top-blown converter and other steel-making tools that Ying Chengyu had seen in his previous life, they were far beyond the industrial base of Daqin, and Ying Chengyu did not even consider them.

Ying Chengyu originally wanted to continue using the exhaustive method to try, but steelmaking is different from curing excrement. If something goes wrong with this thing, it can really kill you!

Therefore, Ying Chengyu could only study stumblingly. At the same time, he informed the craftsmen of all the steel-making methods such as the steel filling method, and while constantly promoting the growth of the craftsmen, he worked together to study together.

Looking at the 'open-hearth furnaces' of different shapes next to the blast furnace, Ying Chengyu sighed softly: "I am determined to research a method of making iron into steel, but so far I have made no achievements."

“I need better sealed pipes.”

“I need a better blower system.”

“I need more talents to study with me. ”

"Brother, this is the problem I am facing now."

"Brother is well-informed and highly intelligent. Please help me think about how to solve these problems when I have some free time." 
However, Ying Chengyu waited for several seconds, but did not get any answer from Ying Zheng.

Ying Chengyu turned around in confusion and asked: "Brother?"

When Ying Chengyu turned around, he saw Ying Zheng holding an iron shovel in his hand, looking up at the blast furnace in a daze.

Lu Buwei, Wei Liao and all the officials of the Great Qin Dynasty were all staring at the iron hammer in Ying Zheng's hand, their eyes full of blazing heat!

Ying Chengyu became more confused, and raised his voice and shouted: "Brother!"

Ying Zheng subconsciously asked: "Is this a blast furnace?!"

Everyone was stunned. It has been determined that this object was used for sacrifice.

In the end, you told me that this was a blast furnace? !

Ying Chengyu nodded matter-of-factly and said, "Yes, this is a blast furnace."

Many people think that blast furnaces are a product of modern times.

But in fact, as early as the Shang and Zhou dynasties, the shaft furnace, the predecessor of the blast furnace, had appeared in China, which was used to smelt bronze on a large scale.

By the mid-Spring and Autumn Period, with the development of bronze smelting technology, the shaft furnace had evolved into a primitive blast furnace. Although its appearance and structure were very different from those of later blast furnaces, its core principles were the same.

When China entered the Iron Age, China's superb bronze smelting technology was directly used to smelt iron. The blast furnaces originally used to smelt bronze were only slightly modified and put into large-scale iron smelting.

To this day, even the Yan State, which has a low level of metallurgy, has its own iron-smelting blast furnace.

So it would be a big mistake if Ying Zheng couldn’t recognize the blast furnace!

Ying Zheng came back to his senses, stared at Ying Chengxuan with his eyes and said: "Brother Nai has certainly seen a blast furnace."

"But brother Nai has never seen such a tall one. A blast furnace that is as fat as a pillar!”

“Brother Wang, is this really a blast furnace used for iron smelting and has no other uses?”

The blast furnace with the highest output in Daqin Furnace today is only a little over ten feet tall (mostly about three meters), and is generally square in shape. Its appearance looks more like a house than a furnace.

The blast furnace standing in front of Ying Zheng is not only much taller and wider than the common blast furnaces in Da Qin, but its appearance is also very different.

Ying Chengyu sighed helplessly: "I hope this blast furnace can directly help me make steel."

"But it can't do it either!"

" The molten iron produced by the existing blast furnace is too low, the temperature is too low, and there are too many impurities, so I made some improvements to the blast furnace. ”

"Now this blast furnace can produce one thousand two hundred stones (72 tons) of molten iron, which is enough to supply three..." However, before Ying Chengyu could finish speaking, Ying Zheng's eyes suddenly turned to Ying Chengyu, in disbelief. asked:

"Seize the young master?!"

Ying Cheng was slightly startled and repeated: "One furnace can yield one thousand two hundred stones of iron."

Ying Zheng subconsciously clenched the iron shovel in his hand, his eyes filled with fire, and he asked solemnly: "Brother Wang!"

"This matter is related to the country, and there is no room for jokes!"

"Can this furnace really yield one thousand two hundred stones of iron?!"

Seeing Ying Zheng being so solemn, Ying Cheng Xiu also corrected his attitude and said in a deep voice: "Brother, there are no false words!"

"This furnace of iron has just been poured. If brother is free, you can wait here for ten hours."
>
"Ten hours later, you and I will watch the next batch of molten iron coming out of the furnace!"

Ying Zheng asked again and again: "Where is the cost? How much does it cost?!"

Ying Chengyu tapped his temples with his fingers, frowned and said: "I have never calculated the cost."

"Brother The iron ore used was transported from Fushi.”

“The fire in this blast furnace was not generated from charcoal but from coal. However, this coal was also transported from Tunliu. The cost was high. It’s really hard to calculate.”

“If we only consider manpower and do not include the manpower consumed in transportation, the manpower required to produce 100 kilograms of molten iron is only about 10% of the Xianyang blast furnace.”

Ying Zheng nodded repeatedly and then asked: "Is it difficult to build this furnace?"

"Can our Daqin workshops imitate this furnace?"

Ying Zheng did not doubt Ying Zheng at all. Cheng Yu, it was just that the matter was serious and the facts were too exaggerated, so Ying Zhengcai asked again anxiously.

As Ying Chengyu answered Ying Zheng's questions one by one, neither Ying Zheng nor the ministers needed to wait ten hours to fully believe in Ying Chengyu.

Han Cang looked at the blast furnace that was spewing black smoke and murmured: "After I, the Qin Dynasty, destroyed Korea, I gathered many good craftsmen from Korea."

"With the combined efforts of the good craftsmen from the four countries of Han, Wei, Chu, and Zhao, and our good craftsmen from Great Qin, our Great Qin blast furnace can finally achieve nine stones of iron (540 kilograms) per furnace!"

"In the past When I heard the news, I lost my composure."

"I never thought that the blast furnace built by Lord Chang'an could produce 1,200 stones of iron!"

"One thousand two hundred stones!"

Han Cang was ecstatic when Ying Chengyu developed fertilizers to increase the yield per mu, but it was still within the acceptable range of Han Cang. He felt that this was something that humans could do. thing.

But the blast furnace in front of him and the increase in furnace production it brought have far exceeded Han Cang's imagination!

From the furnace producing nine stones to the furnace producing 1,200 stones.

This is a leap of one hundred and thirty-three times!

If the person who developed this blast furnace was not Ying Chengyu, Han Cang would definitely sneer and laugh, thinking that the person was just having a whim!

Lü Buwei stared at the hot molten iron, but his eyes were even hotter than the molten iron: "What's more important is that the output of this iron is not only extremely high, it is even comparable to ten-forged steel!"

"This iron can not only be used to cast farm tools, but can even be used to cast armor pieces and weave armor for grassroots generals!"

"It can be used in farming and war!"

" God bless Da Qin!”

“This is God bless Da Qin!”

Pig iron is indeed not suitable for casting armor, but the fundamental reason why Da Qin does not use pig iron to produce armor is that the iron output is too low. , instead of using a large amount of iron materials to produce armor, it is better to use precious iron materials to forge agricultural tools.

But if Daqin's pig iron production has increased by more than a hundred times, and Daqin's pig iron can be comparable to ten-forged steel, why doesn't Daqin use pig iron to cast armor?

No matter how fragile the cast iron armor is, it is at least much better than stone armor!

Li Si took a step forward, raised his hands with a bang, and shouted loudly:

"Congratulations to the great king! Congratulations to the great Qin!"

Seeing Li Si like this, other courtiers also After coming back to his senses, he and Li Si all raised their hands and shouted excitedly:

"Minister, congratulations to the king! Congratulations to the Qin Dynasty!"

Listening to the cheers of the ministers and thinking of the scene in the future when the entire army of Qin Dynasty is wearing iron armor, Ying Zheng excitedly clapped his hands and praised: "Color! Great color!" 
“Although this furnace is not used to worship the gods, it is more precious than the things used to worship the gods!”

Sacrifice to the gods?

How many million elites do gods have in full armor?

Pull it out and show it to everyone!

Ying Chengyu couldn't laugh or cry and said: "What do you mean this furnace is not used to worship the gods?"

"Brother, you don't think this blast furnace is used to worship the gods?!"

“The smoke emitted by this blast furnace is indeed much more than that of ordinary blast furnaces, but look at the black smoke.”

“Who is a good god willing to enjoy such worship?”

Ying Zheng was slightly embarrassed, but he smoothly ignored the topic. He looked at Ying Chengyu eagerly and said, "Brother Wang has developed such a treasure, why didn't you tell Brother Nai for so long?"

"This is It will be a great joy for everyone to celebrate!"

Ying Chengxuan shook his head and said: "I haven't put much thought into this blast furnace. Everything was just modified to facilitate steelmaking." 
“The current output of this blast furnace is only 1,200 stones, so it’s not worth telling my eldest brother.”
