Li Yan, who couldn't guess Li Shimin's thoughts, didn't delve into it anymore, anyway, this matter was beneficial to the development of Tiangong Academy.

Under the status of "official craftsman" and the corresponding treatment, the craftsmen of Tiangong Academy will only exert greater enthusiasm, which can speed up Li Yan's plan to promote the development of Datang industry to a certain extent.

Li Yan took the holy decree and personally sent Wang De, who came to deliver the decree.

After returning to the Tiangong Academy, a group of craftsmen are still immersed in excited emotions, just now Wang Deke said that tomorrow someone will come to the Tiangong Academy to make a register for their "official craftsman" status level, and it is normal for them to be difficult to calm down.

"You five come with me."

Li Yan called out to the five newly recruited papermakers and forcibly dragged their emotions back on track.

Entering the inner room with the five people, Li Yan took out the brand-new papermaking process that he had spent a long time summing up, and handed it over to the five papermakers.

"I want you to make a batch of samples in seven days, in this way."

Li Yan directly assigned tasks to the five people.

He believes that with the level of detail of the process he has recorded, it should not be difficult to reproduce the paper.

"It's ......"

The five of them gathered together and carefully examined this "papermaking secret recipe"

Li Yan's papermaking technology for them combines the two processes of machine papermaking and manual papermaking, and even requires a hand-cranked mechanical assistance while preparing the paper.

In other words, this papermaking technique involves semi-automatic machinery, and if these papermakers want to reproduce it, they have to ask those carpenters and blacksmiths to help build this "semi-automatic paper machine" according to the drawings in seven days

After the machine is made, the real work of the papermaker is only to adjust the concentration of plant fiber pulp and take and dry the paper.

The paper-making process in the middle is completely controlled by a semi-automatic machine, which realizes the streamlined operation of papermaking.

In this way, as long as the machinery and processes are complete, the paper industry will leave the field of handicrafts and directly enter the field of light industry of mechanized production.

Paper will also enter the mass production stage, and the paper price will inevitably be reduced to a considerable standard.

"You give the drawings to the group outside, and they should be finished in three days."

Li Yan instructed the five people, he was now quite familiar with the group of people who first entered the Tiangong Academy, and he was very clear about their handmaking ability.

This semi-automatic paper machine is not complicated, it is composed of two or three main structures, according to the level of Tiangong Institute, three days are more to say, the reality is likely to be completed in one day.

"Yes."

The five papermakers were amazed, they didn't expect that the papermaking industry could be done like this.

Li Yan waved his hand and motioned for the five of them to leave, it was not early now, he had to go back home early, and tomorrow, he still had to be busy with his marriage.

Of the three in-laws, Li Yan's family hasn't visited yet.

In this way, Li Yan sorted out the information he wrote out in the afternoon, locked the door, and left the Tiangong Courtyard, and returned to his Qin State Mansion.

This night Li Yan was no different from the previous one, he was not anxious about the marriage, but was quite happy in "My World".

In the past two days, Li Yan's experience reserve has returned to the 5,000 mark, and the speed of accumulating experience must be incomparable to that of the past.

"Upgrade as soon as possible, maybe it won't be long before you can get the immortal cultivation module by upgrading!"

Li Yan is still thinking about the immortal cultivation module, people are afraid of death, not to mention the traverser who holds the golden finger, Li Yan never thought that it would be over if he left his name in history.

He, like the ancient Qin Shi Huang, longs for cultivating immortals and longing for immortality.

At the current rate of experience gain, it only takes him about three days to level up again.

While liver experience, while shopping in the quest bar of achievement tasks.

The importance of the achievement level and the experience level are generally the same, and Li Yan will not expect to rely on luck and wait for the Immortal Cultivation Module to smash it by himself, most of his hopes are still pinned on the achievement module store.

"Real Book Mod (Nine-year Compulsory Education Edition): Basic Education is the Most Important (Special Progress Achievement, at least one-third of the nine-year compulsory education textbooks are extracted, based on the average mathematics level of the sixth grade, to achieve more than 80% basic education coverage in Datang, with a reward of 100 achievement points for 5% progress, and 200 achievement points for 10% progress...... ）”

When Li Yan saw the achievement task that came with the real book module, his eyes instantly widened.

It's another special progression achievement, and every 5% increase in progress rewards you with an additional 100 achievement points.

By calculation, he only needs to push the mission progress to 20% to get a full 1,000 achievement points!

If you complete this achievement task completely, it will be a full 13600 achievement points!

Such a number of achievement points is simply an unimaginable number for Li Yan at this stage.

"Is it ......difficult to implement compulsory education?"

Of course, with such generous rewards, the difficulty of achievement missions is not light.

It must be known that the land area of Datang today is larger than that of later generations, and if Datang is allowed to develop for a few more years, it is estimated that it will not be too difficult to sweep across the Eurasian continent.

In addition, basic education has a large investment and slow results, and it will be hindered by various families.

And most importantly, the task turned out to be settled at a mathematical level!

If Li Yan dared to set up a school that valued mathematics and despised Confucianism, he would inevitably suffer endless impeachment, and then he would have to face the double pressure brought by the world's scholars and the emperor.

Therefore, the difficulty of this task can be imagined, and it is estimated that reaching 5% of the minimum standard for receiving rewards is not a small problem.

"What are you afraid of, do it! Isn't it just teaching mathematics, Datang preschoolers, fear! ”

Li Yan gritted his teeth and made up his mind directly.

You know, mathematics is definitely the cornerstone of science and engineering.

If industry wants to develop, the theoretical foundation must be laid.

The so-called theory is mathematics, physics and chemistry, of which mathematics is the cornerstone of the cornerstone.

Perhaps the role of mathematics was not reflected much in Datang's first industrial revolution, but if Li Yan wanted Datang to further develop science and technology, then mathematics must be the top priority.

Thinking of this, Li Yan directly sorted out the mathematics-related textbooks in his backpack.

Li Yan has obtained all the mathematics textbooks from the first to the third grade, and he is still alive in the three sets of people's education, Jiangsu education, and Zhejiang education.

But if you want to really make it work, Li Yan has to make it up himself, otherwise even if it is extracted, the Tang people will not be able to understand it.

"Fortunately, the paper industry has begun to develop, otherwise it would be really difficult."

Li Yan muttered to himself.

To be honest, Li Yanzhen felt that his luck was not bad.

Without the thick and outrageous "Four Great Inventions of Ancient China", Li Yan might not have been able to promote the development of the paper industry so easily.

At most, like other traversers, he can only tinker with the fragmentary methods in his memory to improve the quality of the paper, and it is difficult to achieve low-cost mass production.

If we don't even have the capacity to mass-produce paper, then promoting the popularization of basic education is pure nonsense.

"Huh? Is it dawn? It's not good, I made an appointment with Cheng Yanjin to go to Changsun's house today! ”

Li Yan looked at the sun in "My World", and suddenly felt bad, and felt withdrawn and returned to reality.

Sure enough, it was almost eight or nine o'clock in the morning, and if Li Yan didn't set off again, he would not be able to catch up with the time agreed with Cheng Yanjin.

He got up slowly, changed his clothes, went out immediately, and walked quickly all the way to Cheng Yanjin's mansion.

In just five minutes, Li Yan arrived at Lu Guogong's Mansion and met Cheng Yanjin.

"Virtuous nephew, how do you say it now, you are also a prince, it is best to bring two guards to travel on weekdays, and take a carriage ......"

As soon as he saw Li Yan, Cheng Yanjin began to chatter.

Of course, this is not Cheng Yanjin's voluntary!

Just yesterday, Cheng Yanjin was just about to go to bed when he received a secret letter from the palace.

Li Shimin had almost no concealment of Cheng Yanjin, and directly explained that Cheng Yanjin taught Li Yan some basic details, including things like the etiquette specifications of nobles.

At the end of the secret letter, Li Shimin specially told Cheng Yanjin that Li Yan's body may be a little weak, and it is best to travel by carriage.

All in all, the content of this secret letter is like an old father's chatter, and the corners of Cheng Yanjin's mouth twitched when he read this secret letter.

"Yes, yes, taught."

Li Yan didn't know that these words were relayed by Li Shimin to Cheng Yanjin, he just kept nodding his head.

Of course, yes to yes, as for whether to do it or not is another matter.

When Li Yan first arrived in Chang'an City, he actually didn't have a carriage.

But after experiencing the bumps of pure wood interiors and solid wood tires, I decisively gave up this mode of travel.

There is no such thing as a carriage, there is no shock absorption, how does Li Yan sit and feel his buttocks.

As for traveling on horseback, that's even more nonsense.

The flow of people in Chang'an City is not low, Li Yan is a brain-dead second generation, and the speed of low-key horseback riding is not as fast, Li Yan decisively chose to walk out on weekdays.

"Uncle Cheng, let's go."

Li Yan is not like ink, he just wants to deal with these miscellaneous things as soon as possible, and then hurry back to compile math textbooks.

As for why Li Yan gave his marriage to the spot, it was naturally because the temptation of cultivating immortals was much more than getting married.

"Okay."

Cheng Yanjin was a little helpless, since Li Yan came out on foot, he couldn't take the carriage by himself, he and Li Yan walked towards the Changsun Mansion on foot.

"Uncle Cheng, are we going in the wrong direction?"

After Li Yan walked for a while, he found that something was wrong, and the route to Changsun Mansion didn't seem to be like this.

"That's right, we didn't go to the eldest grandson Wuji's mansion, we went to the eldest grandson Wuyi's mansion, and you took the niece of the eldest grandson Wuji's old thing......"

Cheng Yanjin glanced at Li Yan helplessly.

FeelingsLi Yan didn't even know who his marriage partner was, and he had to explain it one by one.

"I see, the ...... of the Wang family and the Cui family"

"Yes, it's not the two you think, we have to go to Chang'an tomorrow."

Only then did Li Yan figure out the situation.

Feeling that things are not as simple as you think, and this visit route is much more troublesome than expected.

"It's annoying, and it's going to waste a few days......"

Li Yan muttered to himself in a low voice.

“？？？”

Cheng Yanjin heard Li Yan's self-talk, and his head was full of question marks.

What is a waste of time?

Is it a waste to work for a marriage?

This kid doesn't know how troublesome it is to marry a woman from the eldest grandson's family and the five surnamed Qiwang families, right?

If it weren't for Li Shimin's marriage, how could Li Yan be able to settle a family affair after three trips? Usually, a family runs more than a dozen times, which is not to say!

"Uncle Cheng, let's hurry up, I have to go to Tiangong Academy today."

Li Yan was still worried about compiling the textbooks, and he didn't put the marriage matter at all.

"Wait! Have you prepared the dowry? ”

Cheng Yanjin suddenly remembered one thing, the main purpose of this trip was to be hired, what happened to these two people empty-handed?

"Hired?"

Li Yan looked confused, if it weren't for Cheng Yanjin's reminder, he really wouldn't have remembered this stubble.

Seeing Li Yan's expression, Cheng Yanjin instantly understood that Li Yan really didn't prepare anything, and he really went to deceive other people's daughters empty-handed.

"Let's go and get ready, we'll ...... later."

Cheng Yanjin only felt that his brain hurt a little.

He didn't have such trouble getting married in the first place!

If it weren't for the fact that the emperor had handed over the matter to him by default, he really wanted to pick his son and leave.

"Okay."

Li Yan nodded hurriedly.

As a "little white" in this regard, he can only obediently listen to Cheng Da's matchmaker's words, and whatever Cheng Biting Jin says, he will do it.

So, the two of them consulted and went directly to Li Yan's Qin State Mansion.

The dowry is not challenging for Li Yan at all.

Although Li Yan has no interest in money and has never touched money, if he dares to say a poor word, then no one in the entire Chang'an will dare to call himself rich!

It is important to know that since the opening of Xianyunju, business has not stopped.

Almost all the wealth of Chang'an nobles was quietly plundered by Xianyunju.

In the end, after thinking about it, Li Yan chose to give such a dowry.

A thousand taels of silver, a set of glazed tea sets, and a gold card of Xianyunju!

The list of dowry gifts is not long, but the value is as high as nearly 20,000 yuan, that is, 20,000 taels of silver!

Looking at the world, how can anyone give such a valuable dowry.

20,000 taels of silver, which is the accumulation of the top gate valve for more than half a year.

Of course, for Li Yan, this is nothing at all.

The silver thousand taels are earned from the family gate valve, and the thousand taels just seem to be too much, but in fact they are just the flowing water of the idle cloud residence for several days.

The glazed tea set, the glass block extracted from "Minecraft" is burned by itself, how much and how much it wants, a monopoly luxury, and it is not worth much at all.

Xianyunju voucher card, this is even more outrageous, although it is a voucher card worth a thousand yuan, but it basically has no value.

Anyway, Xianyunju is famous for its huge profits, and the profits are usually about 100 times, and the mere Wanguan voucher card is also worthless to Li Yan.

After finalizing the dowry, Li Yan set off again and went straight to the eldest grandson's mansion.
