I am the cook, but I am Li Er's son-in-law

When he said these words, Yin Xuan also thought carefully.

Patent this thing...

It can allow researchers and inventors to eat meat, so that their hard work will not be wasted, but there will be gains and losses. When this thing appears, it will inevitably cause the immobility of knowledge.

And knowledge is in circulation, will produce qualitative change.

Researchers must not be able to eat meat, at least a comfortable life must be guaranteed, and at least a class transition must be guaranteed.

But we can't let the "non-circulation" last for too long.

Otherwise... the progress is too slow, and this is not what Yin Xuan wants to see.

So after a compromise, Yin Xuan came up with such a way - not to go through the Tang court, but to make an order from him alone.

After the scientific research is on the right track and the outbreak period has passed, we will consider letting Datang Chaotang pass the patent period.

At that time, it will not be just five years.

Of course...Yin Xuan can also be shameless, learn to be the face of a certain country, I can use the things you research for free, but you are not allowed to use the things I researched, you must buy mine!And there is no guarantee of quality.

With his current status and power, it is very easy to do this.

There may be some fish that slip through the net, but it will not affect Yin Xuan's monopoly.

But if this is the case, what is the difference between Yin Xuan and the aristocratic family he has always looked down upon?

As a human being, you still have to have a conscience.

As for making a lot of money, isn't it the most normal way to improve quality and output?

The merchants in the restaurant suddenly realized that it was no wonder that the first two methods mentioned by Mr. Zhengyang just now were like that. It turned out that they were buying technology.

Lead by example, to fulfill this rule?
Although...this rule may not be useful to Yin Xuan, after all, there is no one in Tang Dynasty who is richer and more prestigious than Yin Xuan.

No one would choose not to sell their technology to Mr. Zhengyang, right?
The merchants were restless.

This... If I can research something like this, will I have a chance to become a great merchant?Not to mention that he can be compared with Duke Zhengyang, after all, he is the Duke of the county, and he is just a merchant.

But...becoming a great merchant second only to Duke Zhengyang.

Just thinking about it, they felt as if an overwhelming amount of copper coins had been dropped on them.Hmm... No, copper coins are too painful, let's change them to banknotes.

Speaking of paper money.

The banknotes printed by the imperial court are already being issued, and they are slowly spreading to places other than Chang'an—of course, only the cities along the railway line.

Datang is now paying more and more attention to the importance of railways.

There is no such thing as stealing railways.

Ordinary people can't do these things - what's the use of these things for them, and now there is no recycling of waste products, and industrialization has not yet taken root in Chang'an.

It can only be used as a farm tool if it is stolen.

But who would commit the crime of decapitation for the sake of some farm tools?

That is to say, Juzhou, the people from the area near the sea in Goguryeo, including some civilians who used to be Silla and Baekje. Since the railway is something that Tang Dynasty cares about, it must be a good thing.

So he built a section of railway overnight, planning how to sell it for money-but before he could make a plan, he was caught, sentenced to death, and sent to Chang'an.

There are even... there are those who are not clear-headed. After poking out the railway, they ran to the governor's mansion in Juzhou, swaggered and put the railway at the door, and then yelled that Datang would give it to him at the price of one hundred guan. Acquire the past.

The guards in front of the governor's mansion looked straight at him.

Do you really think that the railway is something that is naturally raised?

It's good to take the initiative to deliver it to the door, so as to save my group of people from bothering to catch it.

Of course, Yin Xuan didn't have much to do with the railway and banknotes. Although Wu Jue sent the account book, Yin Xuan didn't take a look at how much money he had made from the replacement of banknotes.

Just by looking at Wu Jue's face, one could tell that this was an exaggerated astronomical figure.

The matter of the fountain pen is on the agenda, but the production of this thing is still more troublesome than toys and other things. After all, although the nib of the fountain pen does not require such sophisticated technology, it is more or less a fine part.

There is a lathe.

There is no assembly line yet, and the movement of the steam engine has not been studied to that extent by Fengchao, and the construction of the entire system is a long process.

It's the same even if Yin Xuan gave them the answer. To be able to do this is already the result of a lot of resources.

actually…

What Wang Gui said is correct, but it is not the world raising Chang'an, but the world raising Tang.

Datang used genuine copper coins to exchange for these things before, but now it is even more lucrative, just using some paper with scribbled words in exchange for a lot of resources.

After the winter snow falls, Fengchao can come up with a feasible production plan.

It's just that... the cost can't be suppressed. The wooden pen holder and the copper nib don't use many materials, but counting so many processes and the manpower consumed by the process.

The cost of a pen is almost a hundred cash.

Considering the market for things like fountain pens, Wu Jue didn't make too many strides, but just pulled a production line with more than ten people, and the daily output was not much, only more than 200 pens a day.

The selling price is also more expensive than brushes, a pen costs five hundred cash.It is incomparable with those expensive brushes, but it is also much more expensive than the pens used by ordinary scholars.

but……

The production is small and the price is expensive, which does not affect its popularity.

The practicability of the pen is very high. When reading, taking notes, and researching things, you can't write slowly like calligraphy.

The imperial court buys half of the quantity every day-every department needs such a practical pen.

The remaining half of the amount was naturally snapped up by scholars from all walks of life.

In addition to being easy to use, the most important reason why fountain pens can be dumped every day is the advertising slogan that Wu Sui came up with.

"The No. [-] Scholar card is recognized by Zhengyang Gong."

In Yin Xuan's opinion, this sentence is a bit embarrassing. I can't wait to dig out another Chang'an city and change all these people. What is this thing!
But for the readers of Datang, this sentence possesses unparalleled magic power.

Which of them doesn't want to be recognized by Zhengyang Gong?
Although...they knew the unspoken part of the advertisement, the so-called "recognized" did not refer to them, but to the Zhuangyuan fountain pen.

But if you use the Zhuangyuan brand fountain pen, will it be a step closer to being recognized by Zhengyang?
I have to say that Wu Jue is a genius.

She has already begun to learn how to swindle and abduct this group of scholars out of money.
