As the name suggests, it is the residue left behind by iron ore after iron smelting.
Since it is called residue, it is understandable... In Li Sheng's original history, this kind of slag has always been regarded as useless.
In this life, it is still the same.
But this is not a big problem for Li Sheng.
Since things like slag are subconsciously considered waste, the price can be imagined...
There is no price at all, it’s completely free!
Of course, this is not accurate.
Li Sheng saw this, so he specially said hello to Ying'er, don't say you want to buy slag then.
To put it bluntly, you can find someone to help transport the slag, and then...
In turn, let Li Er's steelmaking blast furnace give him some money...
So in the end it only cost money to recruit civilian workers, rent horse-drawn carriages and ox-carts to transport the slag, and then deduct the official processing fees... the whole process was almost free of charge.
Completely for nothing...
Despite this, Li Sheng did not have any psychological burden.
With this steel-making technology, you can't make yourself a county boy or something like that?
You don’t have anything, why don’t you let me wipe some wool?
In short, with such a high-quality supply of cement raw materials, Li Sheng quickly took advantage of it and fired a batch of high-quality cement.
In addition to the original version of cement fired from clay lime, Li Sheng's Chengxi College soon expanded with countless buildings.
The classroom has turned into several small third-floor buildings.
Accommodation turned into a small two-story courtyard.
Of course, this scale is actually not very large, and even compared to the mansions in a few squares in the south of the city, it is still shabby.
But the living experience is definitely not on the same level.
Compared with rammed earth and wood buildings, cement buildings are warmer in winter and cooler in summer, and have stronger shielding ability. When the wind and rain come... it was also a problem before, but now?
Don't worry about it at all!
The most important thing is that since there is no wooden structure in the cement building, there are no insects...
This alone made Li Sheng feel like he was reborn.
The dormitories of several maids, Teacher Wei, Teacher Fang, Teacher Du... and others are naturally here.
In order to give scholars from far away a place to stay and rest, Li Sheng specially built a dormitory area. Unfortunately, there was no running water or flush toilet. If there were, it would be perfect.
Of course, it would be even more perfect if there is electricity and internet...
It's a pity that they all want to eat shit. Of course, as a shelter itself, this is already very amazing. The scholars who successfully passed the exam and entered the school were all amazed by the houses here.
Of course, no one could tell how this house was built and what materials it was made of. They all thought it was rammed earth made of some rare soil...
Li Er came here with a group of people, and the impression was the same.
I was amazed when I saw that there were actually several buildings standing in this wilderness, and they were well planned.
"These buildings are really exquisite, Keming, Xuancheng, Yaoshi, Xuanling, look at this!"
Du Ruhui and other ministers followed Li Er's gaze.
Sure enough, I saw a bungalow standing on the roadside.
At first glance, this bungalow seems to be nothing special. There are no cornices or carved beams.
Not to mention compared to the inner courtyard of the palace, even compared to their official residence, it seemed very ordinary.
but……
Even for such a small house, the angles and lines around it are extremely square and precise.
It's incredibly accurate!
At first, everyone just thought this small house was a little unusual.
But I soon understood what Li Er meant.
This house is so exquisite!
“It’s such a blessing to be able to turn clay into rammed earth and do it so skillfully!”
Fang Xuanling stroked his beard and smiled, "Your Highness is so lucky. I don't know where to find craftsmen with such exquisite skills."
"..."
Du Ruhui said nothing.
He was the first person to follow Li Er and see His Highness.
The day Queen Changsun recognized His Highness, he was by her side.
His understanding of Li Sheng is also deeper than others.
According to his intuition...this house must contain some kind of magical ability, and it must be the work of the young master!
But thinking about it rationally, I can't help but feel that my idea is a bit ridiculous.
After all, this young man is not really a fairy. How can he even build a house and be able to do it so well?
Wouldn't that mean that gods really descended to earth? It's impossible.
Shaking his head, Du Ruhui told himself that this must be an illusion...
After a while.
Li Er saw a passing scholar and stopped him.
"Brother, please excuse me. I'm here to visit the principal of your academy. Where is the principal at this moment?"
"You want to see the chief? The chief is in the office, but right now... you may not have time to meet the guests. You should come back at noon."
"Don't have time to meet guests? Brother, this is Mr. Li, a first-class wealthy businessman in Chang'an. He has countless connections in the court..." Seeing that the other party did not give directions, Fang Xuanling started to talk about it on the spot.
However, it was unexpected.
The scholar gave him a disdainful look.
"Since you are here to visit the mountain chief, don't you know who the mountain chief is?"
"The Immortal of Poetry, the Immortal of Musical Instruments, the Immortal of Confucianism, the Immortal of Martial Arts, and even more so, your Majesty today..."
"...A person like Shanzhang can only exist in the sky and not on the earth. You can see it if you want to see it?"
Li Er:......
Li Er and others were speechless after eating a lot of pai tou for no reason.
They looked at each other and exchanged a look. Everyone's eyes were clearly saying one thing...
It's not necessarily a good thing that His Highness is too talented...
A few people had no choice but to coax the scholar with nice words, and finally asked where the legendary "office" was, and then walked towards a courtyard...
The entire campus area is divided into several courtyards.
As soon as they entered the door, Li Er and others were startled.
This courtyard is so beautifully decorated...
Wei Zheng opened his eyes even more. Although there were no rockeries or flowing water in the courtyard, the trees were well-proportioned and the sunlight was very regular. From the perspective of his Taoist education background, he could tell that the courtyard was full of sunshine every day.
From sunrise to sunset, the sun and shade are about two to one.
Absolutely amazing!
Everyone stood at the door of the courtyard and looked inward for a while, speechless for a while, and then walked into the courtyard.
But as I walked, I encountered another hurdle this time.
"stop."
Then, a strong, muscular man walked out of the small house at the entrance of the courtyard and stopped everyone.
"What do you do? Why do you come to the office area?"
"Office area...what is the office area?"
"Ha! At first glance, you are countrymen from Chang'an. The office area is where our professors work and prepare lessons. What do you want to do when you come here? Register first."
Li Er was speechless, but Du Ruhui and other ministers were secretly surprised.
This college is too well-organized. Is this a small court?
