Looking at the cement pillar in front of him, Chu Ze knew that yesterday's experiment was a success. However, the hard work paid for this is also very huge. In the past, I only heard a little about how this cement is made. However, I don't know anything about the ratio of various raw materials. In the past few days, Chu Ze has been experimenting.

"Okay, Cheng Chuliang, don't hold it, don't you think this thing is a little cold. It's a gold ingot."

Seeing that Cheng Chuliang was still hugging the cement pillar tightly like a baby, Chu Ze could only remind him.

"Hehe, I just thought, it's kind of amazing."

Hearing Chu Ze say this, Cheng Chuliang scratched his head a little embarrassed, smiled at Chu Ze and said, and then put the cement pillar back on the ground.

"Actually, this thing is really a good thing, and it's very useful..."

Cheng Chuliang sighed after listening to Chu Ze's words, "Good baby, really good baby." There is such a magical thing, in the future, whether it is building a house or building a bridge and paving a road, it will definitely get twice the result with half the effort.

Chu Ze said lightly, "However, it's a pity, this thing is good, but it's too troublesome to do." If you want to produce it in large quantities, there is no door. ”

Hearing this, Cheng Chuliang frowned, and the excitement on his face turned into disappointment.

Cement, without a doubt, is definitely a good thing to come from, and it is extremely versatile. Building houses, roads, bridges, especially when building piers, with it, it is definitely much simpler. As for the use of water canals and the like, it is even more superb. If it can really be produced in large quantities, it will definitely be a great blessing for the whole society.

It's a pity that this thing, if it is put into the modern society of later generations, does not belong to any high-tech products, and the cement of later generations can also be widely used, and the price is not high.

However, in this Datang, it is impossible. Let's talk about how Chu Ze came up with this thing.

But let's talk about the two most difficult processes.

The first is to break up large pieces of limestone into small gravel. This job alone is scary enough. There is another one, that is, the calcined mixture, which is ground into powder by stone grinding, which is another tiring work.

Not to mention the calcination of these things, these two processes alone are destined to not be produced in large quantities in this era. Even if it is produced in small quantities, including the cost, it is definitely sky-high.

The reason why this is so is because, in this era, there are no such large machines to use, and it is completely manual.

In the following days, Chu Ze fell into complete busyness. After all, this time it was to build his family's house, and he had to take care of everything on the construction site.

And because the structure of the house is very different from the houses of the villagers, in many places, Chu Ze must be present and personally commanded, so that everyone can understand how to do it.

Chu Ze was directing the craftsmen to reconcile the cement, when he suddenly heard a loud roar outside the courtyard.

"The holy decree has arrived, where is Chu Ze, the son of Yangquan County? Hurry up! ”

Two people wearing purple brocade robes and high-headed hats stood outside the courtyard of the Li family, their faces were white and beardless, their expressions were indifferent, they were about thirty years old, their eyes did not look at everyone, but they only looked coldly at the sky, looking extremely arrogant.

The busy people inside and outside the courtyard of the Chu family were frightened, and they were busy and consciously separated from each other.

The two of them were not polite, glanced at everyone lightly, and swaggered into the courtyard.

"Where is Yangquan County? Come and take the order. ”

Everyone stood stupidly, their eyes focused on Chu Ze, their eyes full of shock.

Chu Ze hurriedly stepped forward, knelt down towards the two, and said, "Chu Ze takes the order." ”

Chu Ze knelt down, and all the people inside and outside the courtyard knelt down, hanging their heads and not daring to move.

The two of them were quite feminine, obviously the palace attendants, and when they saw this, they couldn't help but snort, and began to recite the holy decree with expressionless faces.

The holy decree is not too formal, in fact, it can only be regarded as the dictation of His Majesty Li Er, and I have to admit that the current Chu Ze has not yet asked His Majesty Li Er to use the qualifications to give him a holy decree in writing.

"Yang Quanxian Zi Chu Ze, the instrument is magnificent, the demeanor is chong Miao, the instrument is Shen Yi, the knowledge is clear, and the opportunity is long. Today, I will give the country a special superintendent to study, and I hope to study hard....."

There is no flowery rhetoric, and there is no so-called "Fengtian carries the emperor, edict" and the like, His Majesty Li Er's face is still relatively thin, and the shameless words of "Fengtian carrier" are probably not too embarrassed to say, after all, the old Li family is also from a noble family, and it is very shameful.

After the Tang and Song dynasties, the emperor surnamed Zhu didn't care so much, his culture was not high, he was born with mud legs, how to exaggerate how to come, a poor man called Huazi and a monk and a small leader of a cult organization, he actually became an emperor in a daze, is this not enough "Fengtian carrier"?

The format of the holy decree of the Tang Dynasty did not pay much attention to the system at the beginning, and there was no sentence that spread all over the streets and alleys in later generations, "Fengtian transport, the emperor's edict", the beginning of the decree is generally "system said" or "剌曰", very formal such as the canonization of the prince, the sealing of the concubine, etc., so directly use "edict".

In a format like Chu Ze now, there is not even a "system saying" at the beginning, and he goes straight to the point when he opens his mouth, in addition to showing that His Majesty Li Er is a very straightforward person and is informal, it also shows that Chu Ze ...... Don't have that face?

After the holy decree was recited, the chamberlain looked at Chu Ze quietly and said, "Yangquan County, thank you for the decree?" ”

Chu Ze knew that according to the procedure, it was time to kowtow and thank him, so he fell to the ground and said, "Thank you, Your Majesty for your grace." ”

Chu Ze didn't understand much of the words in front of His Majesty Li Er's will, and he thought that he should have praised him, and he praised him very hard. But he understood the latter sentence of the Guozijian who went to school.

I remembered that His Majesty Li Er said in the Liangyi Hall before that there would be a will come to the door in a few days, and it turned out that this was it, "But I don't want to go to school, I don't want to accept the poison of feudal ideology!" Chu Ze kept complaining in his heart.

The scale of Guozijian is very large, no less than that of later universities. It is said that His Majesty Li Er built more than 1,200 additional school buildings for the school at one time.

There are 6 majors in Guozijian, namely Guozixue, Taixue, Four Studies, Law, Calligraphy, and Arithmetic. Among them, Guozixue, Taixue, and the Four Disciplines mainly study Confucian classics and are used to cultivate generalists, while law, calligraphy, and arithmetic are used to cultivate specialists.

Such a high-level school, of course, is not something that any cat or dog can enroll, this is a noble school in the Tang Dynasty, and there are strict restrictions on the source of students.

Guozijian has clear requirements for students' family backgrounds, they must be the children of officials, and Guozixue is the most demanding among them, and only the children and grandchildren of senior officials above the third rank are eligible for admission. In the eyes of others, Chu Ze can be regarded as shit luck, His Majesty Li Er personally issued an order to let him go to Guozijian to study, but what Chu Ze thought in his heart, only he knew.
