Chapter 840 This Is a Leap of 133 Times! God Has Millions of Fully Armored Elite Soldiers?

Seeing Ying Zheng's firm attitude, Ying Chengjiao didn't get angry with him.

Reaching out and picking up an iron pickaxe from the table, Ying Chengjiao handed it to Ying Zheng and said, "What do you think?"

Ying Zheng was puzzled, but he had already taken the still warm pickaxe.

First, he tapped it lightly with the back of his finger to listen to the sound, then held the two sides of the pickaxe with both hands, twisted it hard, and finally put the pickaxe on the table, drew his sword and chopped it down hard.

"Dang~~~"

The sound of metal clashing exploded, and the pickaxe that had just come out had not even been chopped once, but Ying Zheng had already chopped out a gap the size of a fingertip!

Picking up the pickaxe again, after carefully observing the cross section and lines, Ying Zheng gave his evaluation: "This pickaxe is about ten forgings."

"Is that what you said, brother?"

Ying Zheng had a very confident smile on his face.

The reason why Ying Zheng clearly expressed his love for swords was to increase the enthusiasm of the metallurgical industry and to leverage the power of all parties to vigorously promote the development of the Qin metallurgical industry.

Because Ying Zheng knew that only sharp swords and solid armor could help Ying Zheng better unify the world!

However, Ying Chengjiao sighed softly: "Is it only at the level of ten forgings?"

The smile on Ying Zheng's face slowly faded, and he was even more puzzled: "This hoe was given to you by my brother."

"My brother, don't you know how many times this hoe has been forged?"

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

"How to forge?"

Looking at the broken iron hoe head in Ying Zheng's hand, Ying Chengjiao frowned and said: "Even if hematite is used, the directly cast finished product can only reach the level of ten forgings."

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

"If you want to achieve it in one step and expand production, you still need to make a flat furnace."

"But this thing is too difficult to make!"

Being able to improve the blast furnace, make coke, extract coal gas, and complete the preliminary preparations for the coal-steel consortium has exhausted Ying Chengjiao's brain cells.

But Ying Chengjiao had never seen a Thomas converter or an open-hearth furnace in his previous life. He only knew their principles. He needed to design and manufacture them based on the principles and the industrial foundation of the current Qin Dynasty, and he also needed to improve the industrial level of the upstream industrial chain.

As for the oxygen top-blown converter and other steelmaking tools that Ying Chengjiao had seen in his previous life, they were far beyond the industrial foundation of the Qin Dynasty, and Ying Chengjiao didn't even consider them.

Ying Chengjiao wanted to continue to use the exhaustive method to try, but steelmaking is different from treating manure. If something goes wrong with this thing, it can be fatal!

So Ying Chengjiao could only study it stumblingly, and at the same time, he told the craftsmen all the steelmaking methods such as the pouring steel method, and while constantly promoting the growth of the craftsmen, he worked together to study together.

Looking at the various ‘open hearths’ next to the blast furnace, Ying Chengjiao sighed softly: “I want to research a method to turn iron into steel, but I have made no progress so far.”

“I need a better sealed pipe.”

“I need a better blast system.”

“I need more talents to study with me.”

“Brother, this is the problem I am facing now.”

“Brother, you are knowledgeable and intelligent. Please help me think about how to solve these problems when you are free.”

However, Ying Chengjiao waited for a few breaths, but did not receive any answer from Ying Zheng.

Ying Chengjiao turned around and asked in confusion: “Brother?”

As a result, when Ying Chengjiao turned around, he saw Ying Zheng holding an iron hoe in his hand, staring at the blast furnace in a daze.

All the Qin officials, including Lu Buwei and Wei Liao, stared at the iron hoe in Ying Zheng’s hand, their eyes full of heat!

Ying Chengjiao was even more confused and shouted in a loud voice: "Brother!"

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

I have already determined that this thing is used for sacrifice.

So you told me that this is a blast furnace? !

Ying Chengjiao nodded as a matter of course: "Yes, this is a blast furnace."

Many people think that blast furnaces are modern products.

But in fact, as early as the Shang and Zhou dynasties, the predecessor of blast furnaces, vertical furnaces, had appeared in China for large-scale smelting of bronze.

By the middle of the Spring and Autumn Period, with the development of bronze smelting technology, vertical furnaces had evolved into primitive blast furnaces. Although their appearance and structure were very different from those of later blast furnaces, their core principles were the same.

When China entered the Iron Age, China's superb bronze smelting technology was directly used in iron smelting. The blast furnaces originally used for smelting bronze were only slightly modified and put into the iron smelting business on a large scale.

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

So it would be a big mistake for Ying Zheng to not recognize the blast furnace!

Ying Zheng came back to his senses, stared at Ying Chengjiao and said: "Brother, you have certainly seen blast furnaces."

"But you have never seen such a tall and fat blast furnace that is shaped like a pillar!"

"Brother, is this thing really a blast furnace used for iron smelting, and has no other uses?"

The highest blast furnace produced by Daqin today is only a little over ten feet high (mostly about three meters), and the overall shape is square. It 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 Daqin, but also looks very different.

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

"But it can't do it!"

"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 have made some improvements to the blast furnace."

"Now this blast furnace can produce 1,200 dan (72 tons) of molten iron, enough to supply three..."

However, before Ying Chengjiao finished speaking, Ying Zheng's eyes had already turned to Ying Chengjiao, and he asked in disbelief:

"Duo Shao?!!"

Ying Chengjiao was slightly stunned and repeated: "One furnace can produce 1,200 dan of iron."

Ying Zheng subconsciously clenched the iron hoe in his hand, with a strong fire rising in his eyes, and asked solemnly: "My brother!"

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

"Can this furnace really produce 1,200 dan of iron?!"

Seeing Ying Zheng so serious, Ying Chengjiao also corrected his attitude and said in a deep voice: "Brother, no lies!"

"This furnace of iron has just been poured. If you have time, you can wait here for ten Hours."

"Ten hours later, you and I will watch the next furnace of molten iron come out of the furnace!"

Ying Zheng asked again and again: "What about the cost? How much is the cost?!"

Ying Chengjiao tapped his temple with his fingers and frowned: "I have never calculated the cost."

"The iron ore I used was transported from Fushi."

"The fire burning in this blast furnace is not generated by charcoal but by coal, but this coal is also transported from Tunliu by me, so the cost is really hard to calculate."

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

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

"Can the workshops of my Great Qin imitate this furnace?"

Ying Zheng did not doubt Ying Chengjiao at first, but the matter was serious and the facts were too exaggerated, so Ying Zheng asked again with trepidation.

As Ying Chengjiao answered Ying Zheng's questions one by one, neither Ying Zheng nor his ministers needed to wait for ten hours to completely believe in Ying Chengjiao.

Han Cang looked at the blast furnace that was spewing black smoke and murmured: "After my Great Qin destroyed Han, I gathered many skilled craftsmen from the former Han."

"By combining the skilled craftsmen from the former Han, Wei, Chu, and Zhao with the skilled craftsmen from my Great Qin, my Great Qin blast furnace can finally achieve nine stones (540 kilograms) of iron per furnace!"

"When I heard this news, I danced out of control."

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

"1,200 stones!"

Although Ying Chengjiao's research and development of fertilizers made Han Cang ecstatic, it was still within Han Cang's acceptable range. He felt that this was something that humans could do.

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

From the furnace output of nine stones to the furnace output of 1,200 stones.

This is a leap of 133 times!

If the person who developed this blast furnace was not Ying Chengjiao, Han Cang would definitely sneer and laugh, thinking that the man was daydreaming!

Lü Buwei stared at the hot molten iron, but his eyes were even hotter than the molten iron: "More importantly, this iron not only has a very high output, but can even be comparable to ten forged steels!"

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

"It can be used for farming and fighting!"

"God bless Daqin!"

"This is really God bless Daqin!"

Pig iron is indeed not suitable for casting armor plates, but the fundamental reason why Daqin does not use pig iron to produce armor is that the iron output is too low. Instead of using a large amount of iron to produce armor, it is better to use precious iron to forge farm tools.

But if the pig iron output of the Qin Dynasty has increased by more than a hundred times, and the pig iron of the Qin Dynasty can be comparable to ten forged steels, why doesn't the Qin Dynasty use pig iron to cast armor?

Even if the pig iron armor is fragile, it is at least much better than stone armor!

Li Si stepped forward, bowed his hands loudly, and shouted loudly:

"I congratulate the king! I congratulate the Qin Dynasty!"

Seeing Li Si like this, the other court officials also came back to their senses, and followed Li Si to bow their hands loudly, and shouted excitedly:

"I congratulate the king! I congratulate the Qin Dynasty!"

Listening to the cheers of the officials, thinking of the future scene of the Qin Dynasty's entire army wearing iron armor, Ying Zheng excitedly clapped his hands and praised: "Colorful! Great color!"

"Although this furnace is not used for worshiping gods, it is more precious than the things for worshiping gods!"

Worshiping gods?

God has millions of fully armored elites?

Pull them out and show me!

Ying Chengjiao was at a loss for words and said, "What do you mean this furnace is not used for worshipping gods?"

"Brother, you don't think this blast furnace is used for worshipping gods, do you?!"

"This blast furnace does emit much more smoke than ordinary blast furnaces, but look at how black the smoke is."

"Which good god would be willing to enjoy such worship!"

Ying Zheng was a little embarrassed, but he tactfully skipped the topic and looked at Ying Chengjiao eagerly and said, "My brother has developed such a treasure, why didn't you tell me!"

"Such a great joy, it should be celebrated by the whole world!"

Ying Chengjiao shook his head and said, "I haven't spent too much time on this blast furnace, everything is just a modification made to facilitate steelmaking."

"Now the output of this blast furnace is only 1,200 stones, it's not worth it for me to tell my brother."
