Since the day he traveled to the Tang Dynasty, Li Yuanjia has never stopped colliding with this era in terms of thinking - from eating habits to ways of thinking, from world view to life outlook.

The list goes on.

And today, Chen Mu, Zhang Wan and others, as well as Han Lucheng and others, do not understand, in fact, from this conflict of ideas.

In their opinion, it is a matter of course to cover good things tightly, especially good things like Han Wang Paper, which are extremely high and extremely popular among the powerful; And the top technology that can make a lot of money such as seawater salt drying must be kept strictly confidential and must not be released in the slightest!

The craftsmen who know how to do it are better to protect them all, like the valley where the glass workshop is located.

In their opinion, this is all the wealth of the Han Palace.

It's a pity that they don't know what the king thinks, except for the glass workshop and the dim sum, and the old housekeeper Han Shan sent out in the house, others such as the paper workshop, seawater and salt, etc., although they didn't take the initiative to teach others, but it seems that they have never told everyone to keep it strictly secret or something.

In this case, they can only manage their own people in private, and constantly warn them not to talk nonsense after they go out, and not to reveal the secrets of the house to the outside world......

This difference in philosophy is almost immutable.

The reason is very simple, because Li Yuanjia's way of thinking is completely different from Chen Mu, Zhang Wan and others, and it can even be said that he is now very different from himself more than a thousand years later.

The root of this lies in his identity as the prince of the Tang Dynasty.

This identity put a huge shackle on Li Yuanjia, so that he had to be cautious and cautious, after all, Li Shimin in the early years was really terrible, not only his brothers were terrified, including the famous general Li Xiao of the royal family complimented to prevent suspicion, but also locked himself at home every day, entertaining himself with singing and dancing beauties.

Even though Li Shimin has sat firmly in his position in recent years, his vigilance against his brothers has been reduced a lot under the expansion of self-confidence, and his pursuit of a good reputation has gradually made his attitude more tolerant, but Li Yuanjia does not dare to really "let go of the wreckage".

And......

To be honest, does he really need to make money in this life?

Long before he left the cabinet, the imperial concubine and his uncle Yu Wenshi had prepared everything, such as copper coins, gold and silver, cloth and silk in the treasury of the Han Palace, and hundreds of slaves and tenants. Of course, what is more important is the tens of thousands of acres of fertile land in the name of King Han's mansion, plus the 10,000 acres of vocational land obtained by Li Yuanjia as the prince of Yipin, which is enough to make him the top landlord in the world.

You know, it's just the early years of the Tang Dynasty.

Land annexation is not so powerful, except for some big families, who can own tens of thousands of acres of land, that is, prince-level nobles like Li Yuanjia. In addition, even the upstarts of the Tang Dynasty like Cheng Zhijie and Fang Xuanling don't have so much land under their names, after all, the words are too eye-catching.

So apart from glass, Li Yuanjia doesn't plan to leave too many industries.

Especially the seawater salt drying technology, it is impossible to stay, Li Yuanjia can only think of dedicating it to his second brother Li Shimin, and then let him watch it, if he can reward himself with a large amount of money for this, it would be better.

In addition, there is such a technology as movable type printing, if someone is willing to learn, Li Yuanjia will definitely be eager to hand it over, and if necessary, he can even fund the other party. This thing is really too expensive, and the annual loss can be said to rank first in the industry of Han Wangfu!

Otherwise, Li Yuanjia wouldn't have covered the glass to death, and he was going to use this thing to make money a few years ago......

Making a whole set of metal movable type is really expensive!

Anyway, after calculating all the Chinese characters and the number of movable types needed to print several books at the same time, Li Yuanjia had raised the expected expenditure of the movable type printing workshop in the next ten years to at least 50,000 guan, and perhaps even to 100,000 guan if he felt it necessary......

And this is only the cost of making movable metal type, if you take into account the need to train literate typesetting workers, at least one or two thousand more expenses!

After all, there is a world of difference between the cost of cultivating a craftsman and cultivating a scholar in these years.

He plans to earn all this money back from glass......

Well, that's a long way off.

In a word, even if he was a dick in his previous life, it does not prevent Li Yuanjia from treating money as dung in this life, because he really has no use for asking for so much money.

His prince is enough.

In the upper social circle of this era, everyone likes to compare those things, such as the hunting dogs and horses raised at home, such as the beautiful dancing queen, Li Yuanjia is not interested, let alone the so-called top wine and food.

No matter how top-notch the wine is, can it compare to a glass of draught beer in summer?

No matter how delicious the food is, can it be compared to a meal of sheep and scorpions in winter?

No matter how fun a game is, can it compare to "League of Legends" and "PlayerUnknown's Battlegrounds"?

Compared with enjoying the glory and wealth, Li Yuanjia is still more interested in leaving a name in history - this is a decision made after countless late night thoughts in the past few years, and it is also the best way for him to think that he will live a new life and not feel that it is the best way to waste his time.

So, how old is the money?

Isn't the painstaking improvement of papermaking techniques just to enable the Tang people to use cheaper and better quality white paper? There is also movable type printing, in addition to hoping that the originator of movable type printing will no longer have a rip in the future, Li Yuanjia also hopes that one day in the future, the price of books in Datang can be reduced, so that more people can afford to read books.

There is also the emergence of iron pot stir-frying, in addition to satisfying people's appetites, maybe it can stimulate the development of the smelting industry, after all, the demand to promote technology is not empty words.

There are also seawater salt, overturning and quyuan plows, etc., Li Yuanjia really doesn't know how much impact it will have on this era if he takes them out in advance, or improves them in advance, but when he thinks about it, it can't be a disadvantage, right?

But what is the point of all this if it only exists in the Han Wangfu, or if it is just used to make money for him Li Yuanjia?

Only if it's free and easy to get, can it spread quickly!

So in the reluctance of Chen Mu, Zhang Wan and others, Li Yuanjia just waved his hand and said, "Don't worry, I won't ask you to complete all the drawings right away!" I'll give you three years...... No, I can give you five years to draw slowly, and with patience, you will be able to draw it all sooner or later......"

……

Just when Li Yuanjia was pondering whether to write a Tang version of "Heavenly Creations", Li Shimin, the emperor who was far away in Jiucheng Palace, received a letter from his younger brother.

And after reading the letter, Li Lao Er blinked his eyes and sat on the chair and thought about it for a long time!

What kind of seawater salt drying method can really be so powerful?

And......

Blinking again, Li Shimin reached out and picked up a book on the table...... A very thin, thin, seemingly weightless book, and then a face gradually became serious.

Because on the cover of this book, there are two big square characters written on it.

University!
