The sensation caused by cheap paper in Chang'an was no less than that of the two atomic bombs dropped by the United States on the book, and the paper produced was in short supply, and the more than 1,000 pieces of paper produced in the workshop were bought out on the same day, and some readers even willingly waited all night in order to buy these papers.

Duhe papermaking, in most respects, is for the benefit of the poor scholars, so when choosing the address, he left a mind, the store is not built in Chang'an, let alone in the downtown area, but in Wannian County near Chang'an, and that is, in the fiefdom where Duhe is located.

This has two major advantages, first, because the place is a village, it is more conducive to the purchase of Hanshi, and second, there are 500 guards in the village, who have already lived in the village, by the way to protect the safety of the village, they can rectify the law and order, prevent others from making trouble, and by the way, they can also increase the prosperity of the village, which is considered to kill multiple birds with one stone.

On this day, Du He returned to Cai Guogong's Mansion from the workshop, but saw Du Ruhui and Fang Xuanling drinking tea in the hall. Because this high-grade dragon well is extremely difficult to pick, it is not in a hurry to go on the market, and more inventory is the last word for sustainable development.

But this good thing was tasted by herself first, and the first batch of Longjing was made, and Wu Meiniang personally sent some.

Du He is a good wine, but it is not very good for tea, but it is dispensable, so he gave Du Ruhui a lot, and he only left a little bit.

At that time, Du Ruhui drank it, and immediately became obsessed with the taste, and immediately looked full of emotion, but he didn't say that he drank this tea, only to find that what he drank before was all horse urine. So that every day to drink, like a baby, the guests are reluctant to take out to entertain.

Du He is also secretly happy, drinking too much tea is beneficial and harmless to the body, and I wish he drank more.

But today is special, Fang Xuanling has always been Du Ruhui's iron buddy, they are left and right, political views are the same, one is good at strategy but a little indecisive, the other is not good at strategy, but has a unique vision, the two cooperate seamlessly, both are Li Shimin's right-hand man, belong to the people who wear a pair of pants together, and only he can let Du Ruhui take out this first-class Longjing.

"I've seen my father, I've met Uncle Fang!" Duhe greets them!

Du Ruhui nodded slightly.

Fang Xuanling said with a smile: "The virtuous nephew's every move is amazing. Take this West Lake Longjing, for example, this taste is more than 100 times better than our previous tea! I just don't know where to buy it! As he spoke, he still had a look of unfinished business.

Du He said: "This is a friend who gave it, and now there is no sale on the market, waiting for the time to come, the east and west markets should be able to buy it." The little nephew has some here, if you don't dislike it, uncle take it and drink it! ”

Fang Xuanling's kind face and smiling eyes narrowed into a gap, Fang Du's two families, they were in the same family, and they were not polite, and said with a smile: "In this way, the old man is also disrespectful, the virtuous nephew should sit down and talk!" ”

Du He smiled slightly, knelt aside, originally thought that Fang Xuanling was just visiting the door, but now it seems that he is looking for something to do, and he also asked: "I don't know if my father and uncle have something important to do with their juniors?" ”

Fang Xuanling smiled kindly: "It's about my Tang Dynasty for thousands of years, and the old man is not polite here." Virtuous nephew, the old man is here, only for the papermaking technique. To know something from your father about what happened. It would be a pity that such a remarkable invention could be used as a tool for profit. ”

Hearing him talk about papermaking, Du He also smiled heartily and said: "My nephew also thinks so, so I persuaded Peng Yiliang to lower the price of paper, and not to open a store in Chang'an City, but to choose Wannian County." ”

Fang Xuanling nodded and admired: "The old man has also noticed the heart of the virtuous nephew. It's just that the virtuous nephew doesn't think it's enough? In the past seven days, the old man asked his subordinates to buy them every day, but he only bought ten. In Chang'an, it is in short supply, let alone elsewhere. Although you have the heart to benefit the world, but this move can only benefit the vicinity of Chang'an, not to mention the north, these remote places in the south of the Yangtze River, even the nearby capital Luoyang can not be taken into account, how to benefit the world? ”

Du He nodded, and did not object, because judging from the current situation, what he said was the truth, "Then according to my uncle's opinion, what should it be?" ”

Fang Xuanling said in a deep voice: "Just like Cai Lun back then, I will make this papermaking technique public to the world and share it with the people of the world, so that my Datang will have thousands of workshops." The paper made by the virtuous nephew can also be passed on to everyone in the world in the shortest possible time. ”

Du He was stunned for a while, looking at Fang Xuanling's eyes changed, there was a taste of looking at two hundred and five, and he also secretly wondered: "Why are these celebrities so generous, top-secret technology, don't grasp the hand, but always think about making it public to the world and benefiting the people of the world, haven't you thought that once this thing is made public, it is not only the Tang Dynasty people who will learn, but also millions of alien races in the Tang Dynasty will also master this technology." is just this amount of energy, compared with what Li Shimin has, it seems that the father also means. ”

Fang Xuanling made Du He look a little embarrassed, coughed, and said, "Could it be that what the old man said is wrong?" ”

Du He immediately decided to wake up the famous minister: "It's not just a mistake, it's a mess of mistakes." ”

"Don't be rude!" Du Ruhui frowned and reprimanded.

Fang Xuanling didn't think it mattered: "It's okay, Keming, let the virtuous nephew talk about it." This person is not perfect, everyone is at fault, and maybe there is something we don't care about! ”

Fang Xuanling said this, which also made Du He feel a little surprised, but he also secretly admired.

"If you are a threesome, you must have my teacher; Choose those who are good and follow them, and change those who are not good", everyone will say, but there are a few people who can really accept the opinions of others with an open mind.

There is no doubt that Fang Xuanling is one.

Du He said: "Cai Lun made papermaking public to the world back then, and his little nephew felt that he was not doing it right. It is true that because of him, papermaking has been widely used, but at the same time, it has also been learned by other people. However, with the technology of the time, even after his improvements, the paper produced was still expensive, so it could not be popularized, and it was not a big mistake. The little nephew is different from Peng Yiliang's papermaking technology, which is extremely cheap, and can be regarded as the culmination of papermaking in the world. Once it spreads, not only my Datang will benefit a lot, but even the surrounding alien races can also benefit a lot. If they master this papermaking technique, they will be able to learn the knowledge of our Datang Dynasty more easily, and it will be easier to develop and grow, isn't this equivalent to adding a strong enemy to themselves? ”

Glancing at the two of them in contemplation, Du He continued: "A few years ago, my little nephew said that there are some things that can be shared, such as culture, and cultural exchanges between countries are also of great benefit to my Datang. But there are some things that can never be shared, such as weapons, armor, medicine, and today's paper, these unique technologies. ”

Fang Du and the others understood what Du He meant, and felt that there was some truth, but they were a little disapproving.

Du Ruhui said: "What if they let them learn? My Datang is strong, even if they have the same technology as my Datang, they are still not my Datang's opponents. ”

"That's true, but father, uncle, do you think it's necessary?" Du He raised his voice: "It's obvious that my Datang has the advantage, why do you want the alien race to stand on the same starting line as us?" Let's talk about the armor, my Datang armor is sharp, ten people can break the enemy 30 people, but not one person, but if the enemy has the same armor as my Datang, 10 Datang people can still break the enemy 30 people, but they have to pay the price of two deaths, why bother? ”

"It's the same with papermaking, take Goguryeo as an example, His Majesty's greatest wish is to level Goguryeo, and this battle is inevitable. If I were to make papermaking known to the world now, Goguryeo would surely be able to learn it and spread it widely, so that everyone in Goguryeo could learn cultural knowledge. Among the Goguryeo people who have been influenced by knowledge, it is inevitable that some outstanding characters will appear. It's still the same, I Datang may not be afraid, but why bother asking for unnecessary trouble! ”

These words were true, and Fang Xuanling and Du Ruhui also had to nod in admiration.

Fang Xuanling said: "Virtuous nephew, what you said is not unreasonable, but as the old saying goes: 'The weight of the two benefits is the heavier, and the lesser of the two evils', the papermaking technology will be made public to the world, and the old man does not deny that it will bring a little harm to my Datang from the side, but it can make me Datang millions of people can get benefits, and the benefits still far outweigh the disadvantages." This is also the most critical reason why the old man insists on spreading the papermaking technique. ”

"Being a father means the same thing!" Du Ruhui also interjected at this time: "You alone will never be able to make all the people of the Tang Dynasty able to use paper." ”

Du He suddenly thought that this technique would be learned by other races, but while despising the foreign race, they thought that there was no way to let paper spread all over the world except to make papermaking public. Therefore, there is a saying that "the weight of the two benefits is the heavier, and the lesser of the two evils".

Du He said: "Didn't my father and uncle consider the best of both worlds?" ”

"The best of both worlds?" Du Ruhui and Fang Xuanling were each surprised.

"Not bad! It does not pass on the technology, but at the same time, it can allow all the scholars in the world to enjoy the same treatment. Du He's face was full of bamboo.

"Say it quickly, you have a good way to explain it, don't be sluggish, I'm worried that the old man will whip you!" Du Ruhui was a little anxious, and directly used Lao Tzu's power to beat his son.

Du He can said: "Chain workshop! That is, first choose a trusted person, let him master all the processes of papermaking, and then scatter around Datang to open large-scale papermaking workshops. They are not responsible for buying and selling, only for production. Then they choose well-known and really famous vendors from all over the world as dealers, and they sell the paper everywhere. As long as there are many factories, there is no fear that paper will not be able to spread. ”

He explained the distribution methods of later generations to Fang Du one by one, and the transcendent knowledge made them nod their heads again and again, just like a teachable baby.
