If the red bricks and cement were used well, along with gunpowder and steel, it would only be a matter of time before the Great Tang dominated the world!
However, he was not in a hurry to get the cement and red bricks.
Because cement was very simple.
It was to grind limestone and clay into powder and place it in a blast furnace for firing. Then, it would be mixed with the slag left after ironmaking.
This way, the cement came out.
Just as Li Chengqian was planning what to do first, the crowd suddenly erupted in cheers.
Li Chengqian looked over and realized that with their hard work, a blast furnace was completed just like that!
Looking at the blast furnace that had been completed, Li Chengqian found the steward and asked him to make some tools.
It was something like a crucible.
Without any tools, how could he let Li Chengqian throw the sand into the blast furnace?
The manager said to Li Chengqian with a bitter smile.
"Your Highness, it's almost midnight!”
"Although I can still hold on, the others can't!”
He considered that if he wanted to burn glass, he would need to use coke.
And coke was a very important thing in the future!
This was because if he wanted to make steel, he had to use coke. Otherwise, the temperature would not be enough!
Li Chengqian had yet to get the coke out, but he still asked.
"How long will it take to make a crucible?”
The manager thought for a moment and then raised two fingers.
"No, it's too long!" Li Chengqian shook his head and said.
He opened his right hand.
"I want ten cauldrons by tomorrow afternoon!”
"I'll give you a hundred taels of silver for a cauldron!”
The steward, who was about to shake his head with a bitter smile, instantly widened his eyes.
"Then if there are more than ten…"
Li Chengqian smiled.
"If you have one more, I'll give you an extra 100 taels of silver!"
The manager immediately patted his chest and said in high spirits.
"Your Highness, just wait and see!"
Sure enough, there really wasn't anything in this world that money couldn't buy…
Li Chengqian smiled and shook his head, then went back to sleep.
However, while he was sleeping, in the palace in Chang 'an.
Cheng Yaojin sat in front of Li Shimin with a bag of salt that was as white as snow.
Cheng Yaojin was no stranger to salt because it was a profitable industry!
When he saw the salt and letter that his son had sent back, Cheng Yaojin knew that he could not monopolize the profits.
Therefore, he ignored the night and went straight to the palace to meet Li Shi Min.
Li Shiming looked at the salt in his hand with a complicated expression.
"Such a good child, why doesn't he want to be the Crown Prince?”Li Shi Min muttered to himself.
"Your Majesty, what did you say?" Cheng Yaojin asked in confusion.
Li Shimin shook his head and threw the salt to Cheng Yaojin.
"Let your wife find the Empress."
Cheng Yaojin nodded.
Li Shiming stood up and said to Cheng Yaojin.
"Zhijie, look at this letter.”
Li Shimin handed a letter to Cheng Yaojin.
Cheng Yaojin opened it and looked at it. His expression gradually became solemn.
"Your Majesty, is this true?"
Li Shi Min nodded slowly and said with certainty.
"This is the news from the blanket we planted on the grassland.”
"The plains have already begun to turn cold, and there are already signs of snow in some places!”
Cheng Yaojin's face was full of worry.
"Your Majesty, these Prairie people are like wolf cubs.”
"It's snowing early this year, so they definitely won't have anything to eat. When the time comes, they might really raise an army to attack us for food!”
Li Shi Min sighed.
"How could I not know?"
"If we were to fight with real weapons, our Great Tang would definitely not be afraid of them!”
"But the national treasury doesn't allow it!"
"And the drought in Guanzhong…"
"Although the news from Guanzhong has already spread and Chengqian has basically settled the disaster victims, without the taxes from Guanzhong this year, the national treasury is in a difficult position!”
Cheng Yaojin also sighed.
he muttered.
"If only God could have struck them with a few bolts of lightning when the Huns came…"
The two of them looked at each other and sighed in unison.
They did not know that Li Chengqian had already produced black gunpowder.
Although it couldn't compare to heavenly lightning, it wasn't inferior to it!
The Xiongnu mainly had cavalry.
As for the horses of the cavalry, once they were frightened…
Hiss!
That scene was too beautiful, so beautiful that it was unimaginable!
How could Li Chengqian not know about this matter?
However, he could not hand over the black gunpowder now.
Currently, spies from the aristocratic families were everywhere in the Imperial Palace.
If the black gunpowder formula was leaked, it would be a severe blow to the Great Tang.
Imagine this: one day, an important minister of the Great Tang was sleeping at home when a few packets of ignited gunpowder were suddenly thrown in…
He could also throw a few of them into Chang 'an Fortress or pile a few on the city wall at any time...
It was simply a very terrifying thing!
Li Chengqian had already made up his mind.
The formula for the black gunpowder must not be handed over!
However, he could give Li Shiming some support for the bomb, which was the finished product.
Once there was a water source in Qinghe, he was ready to start making steel.
With steel, there would be elite weapons, and with elite weapons, there would be advanced preparations.
Just imagine, when the Xiongnu fought against the Tang army, the Xiongnu would slash a Tang soldier and leave a white mark on the armor of the Tang soldier.
However, the Tang soldiers had given the Xiongnu a slash, and they had both fallen to the ground!
Moreover, with the addition of gunpowder, this battle was as big as an adult bullying a child.
The adults were the Great Tang, and the children were the Xiongnu.
However, Li Chengqian decided not to tell Li Shiming.
After all, the fewer people who knew the secret, the better!
The secret was to not even tell one's own people. Only then would it have the greatest effect!
Moreover, Li Chengqian could guarantee that among the Great Tang's aristocratic families, there were definitely some who had connections with the Xiongnu!
However, this was all for the future.
The current Li Chengqian was still working hard on how to produce penicillin.
I still owe everyone 21 chapters!
Was everyone still sleeping in the morning?
I don't believe it, I refreshed the background for a long time, but I didn't see a single flower…
The votes!
