Li Chengqian may still have the patience to wait for the times to develop slowly.
But after the battle to aid the Western Turks ended, Li Chengqian felt a strong sense of crisis.
Maybe it's because of his arrival, maybe it's because of other reasons.
The current Western world already has a hint of rising.
And that battle also proved that although Datang's technology is still ahead of them, it has not reached the level of crushing them.
This also forced Li Chengqian to change his plan and take action in advance to promote the rapid development of science and technology.
He knew very well the urinary nature of those careerists in the West.
Once their technological and military power surpassed that of the Tang Dynasty.
Then they will definitely attack as soon as possible and enslave the people of the Tang Dynasty.
Li Chengqian will never allow this to happen.
Therefore, when Liu Min was asked to increase the range of his artillery to 10,000 steps within two months, it was not because Li Chengqian deliberately wanted to create problems for him.
Really, they don't have much time to waste now.
But he knew these things, but others seemed to understand.
Especially Changsun Wuji and Cheng Yaojin.
At this moment, the two of them were in a daze after hearing the conversation between Li Chengqian and Liu Min.
They had just seen with their own eyes the power of the new artillery.
With one shot, the stone mill weighing a thousand kilograms was gone.
If all this power cannot meet Li Chengqian's requirements, then how terrifying must the cannon he wants be?
Both of them looked at Li Chengqian, hoping that he could give them an explanation.
However.
However, Li Chengqian had no intention of explaining the matter. He left the shooting range and walked towards the ordnance camp.
Seeing this, several people could only put aside the problem temporarily and step up to follow.
The current ordnance camp has undergone earth-shaking changes compared to before.
Not only does it have a steam engine, an artifact that can change an era, but it also has a complete R&D system and production system.
Although the hardware facilities here now are not as good as the heavy industrial production chains of later generations. But it is a miracle that these can be established in this era of scarcity of materials.
Li Chengqian drove on a familiar road and stopped outside a single-family courtyard behind the ordnance camp.
Just as he was about to raise his hand to push the door open, there was a sudden quarrel inside.
"I said my surname is Zhu."
"I, Tian Xuan, and you are not at odds with each other. I have never offended you in my life."
"But you keep picking on me again and again. What does this mean?"
In the courtyard, Tian Xuan looked at Zhu Guang with a gloomy face and asked.
Zhu Guang looked helpless: "When did I pick a fight with you?"
"If you want iron, I will give it to you. If you want iron, I will give it to you."
"Even if you want meteorite, I'll get it for you."
"But now you are telling me that the quality of these things is not up to standard and they need to be remade."
Tian Xuan felt insulted.
Think of him as Feng Hu, who has been forging iron for decades. Even if you look at the Tang Dynasty, he is still one of the best swordsmiths.
This was the first time he heard someone say that the quality of the iron he made was not good, and they said more than once, if this is not looking for trouble, then what is it?
"The quality of your iron is not up to par, it just isn't up to par."
Zhu Guang rolled his eyes and said, "Can I still insist that the quality of the iron you make is good?"
"you!"
Tian Xuan was so angry that he couldn't speak. He glared at him and said, "Okay, then let's take the things and go to His Highness for comment!"
As soon as I said this.
Zhu Guang also put away his idle applications.
"Tian Xuan."
"I hope Guang and you will not work together for just one or two days."
"The first artillery piece was made by the two of us, and the first musket was made by the two of us."
"I Zhu Guang never looked down upon you in the slightest, nor did I mean to disrespect you."
"But
I have to fight you to the end on this matter. If something doesn't work, it just won't work. There's no point in asking anyone."
Zhu Guang narrowed his eyes: "And everything I do is assigned by His Highness. If you have time to find His Highness, you might as well seize the time and think about how to improve the hardness of these irons."
"Promote? Improve your ass!"
Tian Xuan casually grabbed an iron block and said, "This iron is already the best thousand-fold iron."
"If you break the iron into ten thousand pieces, it will break even if you drop it lightly, let alone use it."
"I don't blame you for your ignorance, but don't always tell me the same things you do."
"Anyway, I brought these irons to you. If you use them, you can use them. If you don't need them, take them to the melting house and melt them. Then you can find the iron you need."
After saying this, Tian Xuan threw down the thousand-fold iron block and walked out angrily.
But as soon as he opened the distance, Tian Xuan was stunned.
He said in disbelief: "Your Highness... Your Highness? Why are you here?"
"Come over and watch you quarrel."
Li Chengqian reached out and pulled Tian Xuan's arm, pulling Tian Xuan into the courtyard.
Later.
He walked over to the pile of iron blocks and took a closer look.
Just from the glossiness of the iron surface, you can know that the density of these irons is very high.
It can even be compared with those produced by machines in later generations.
Li Chengqian asked without raising his head: "Where are these iron discs?"
"Return to Your Highness."
Zhu Guangdao: "The difference lies in the hardness."
"hardness?"
Li Chengqian couldn't help but raise his eyebrows.
It's no secret that the higher the density of iron, the harder it will be.
But everything has two sides.
As Tian Xuan himself said, the iron he has tempered is basically the limit of iron weapons.
If we continue to increase the density, the iron will inevitably become brittle.
At that time, let alone using it to build things, it will break even if it is lightly knocked.
Li Chengqian frowned and asked, "What are you going to do? Bring me the drawings and let me take a look. look!"
"good!"
Zhu Guang didn't hesitate, turned around and ran back into the house.
Not long after, he came back with a drawing.
Two big words are clearly marked on the drawing, machine tool!
This drawing was drawn by Li Chengqian himself, and many of the annotations on it are concise and concise.
"Now that everything is done, all that's missing is a machine tool."
Zhu Guang pointed to a component marked as a machine tool knife on the drawing and said: "Your Highness, you see, your requirements are very clear. You want the machine tool knife head to be several times harder than ordinary iron."
"I have tried all the iron he brought, and it is far from meeting the requirements on the drawings."
When Li Chengqian heard this, his eyes became strange.
"What's on your mind?"
"What I'm telling you is that the knife head is several times harder than iron."
He looked at Zhu Guangdao: "But I didn't say I had to ask you to make a knife head out of iron, right?"
Zhu Guang was dumbfounded.
In his mind, the hardest thing in the world is iron.
No need for iron? Then what to use?
Li Chengqian was quite speechless about this.
He said angrily: "You have been a craftsman for so many years in vain."
"Don't you know that diamond is dozens of times harder than iron?"
Zhu Guang was stunned.
Obviously, he didn't think about it at all.
"Can diamond be used as a knife head?"
"Otherwise? I want you to take it home and cook it to eat?"
Li Chengqian raised his hand and patted Zhu Guang's head: "When you go back to do things, can you use your brain more?"
Zhu Guang's face was full of embarrassment.
"okay!"
"That's it for today."
"I don't care whether you and Lao Tian have a fight or quarrel and give up."
Li Chengqian didn't want to talk to him about this matter anymore, so he asked instead: "Where are those things I asked you to do half a month ago? Have they been done?"
