Li Shimin knows Xia Hongsheng's situation, and it is not an exaggeration to say that his family has a lot of money, and when it comes to the ability to make money, Chang'an may not be the best. Because Xia Hongsheng's business has never been hidden from him, and most of them have even pulled Li Chengqian or Li Ke into the gang, so Li Shimin understands clearly that Xia Hongsheng is not short of money. But at this time, Xia Hongsheng said that because the method of preventing malaria was his, he gave it to the Tai Hospital, so he had to ask the Tai Hospital for money. Asking for money is just asking for a penny! The dignified Marquis of the founding county of the Tang Dynasty, how could he ever lack that copper coin? So Xia Hongsheng must have other meanings when he did this.

Seeing that Li Shimin let himself speak directly, Xia Hongsheng bowed and said, "Your Majesty, last winter, Weichen made a coal stove and honeycomb coal for heating, and the effect is okay." Compared with the previous heating, or firewood, or charcoal, the charcoal pot in the house, is not warm, unsafe, people are very easy to get charcoal poison. The coal stove made by Weichen can not only warm the people sitting next to it, but also warm the whole house, and the flue gas from burning coal can be put outside through the pipe, as long as the seal is not broken, people will generally not be poisoned by charcoal. And burning coal is much hotter and warmer than burning firewood and charcoal. It is precisely because of so many advantages that coal stoves quickly became popular in Chang'an, and the honeycomb coal used in coal stoves also spread. ”

"Yes, the coal stove is good. Placed in the house, it is like winter going to spring. Li Shimin nodded and said.

Xia Hongsheng nodded, and said: "A few days ago, someone was in the clouds and found that someone imitated the honeycomb coal made by Weichen without permission, but the honeycomb coal he made was of poor quality. It hasn't burned for long before it crumbles into slag. The point is. He pretended to be the honeycomb coal on my Zhuangzi. But it can be made but it can't be used, and if it is sold, it will inevitably damage the reputation of Wechen honeycomb coal, if it spreads, others will say that Wechen relies on the practice that only he knows about honeycomb coal, so he deliberately makes things that cannot be used and cheats people of money. ”

Li Shimin looked at Xia Hongsheng and remained silent. just asked lightly: "Then how did Xiahou deal with it?" ”

"Wechen sent a few skilled people from the coal yard to Yunzhong." Xia Hongsheng smiled and said, "Ask that person for a penny, and then let those skilled people teach him the craft of making honeycomb coal." ”

"Oh? Xiahou's move? ......" Taiyi Ling was surprised on the side: "Isn't that the craft of making honeycomb coal going to be spread, and anyone can make honeycomb coal according to this craft in the future?" In this way, wouldn't Xiahou's business be ......?"

Xia Hongsheng shook his head with a smile and said, "It's okay, I'm not worried about being known." Because whoever wants to use this technology to make honeycomb coal must first pay the next penny and buy it. to be able to use it. So the more people who use this kind of craft, the more people who pay for it. Therefore, more people are not allowed to use such a craft in the chin, where will there be private secrets? ”

Li Shimin narrowed his eyes and stared at Xia Hongsheng, but did not speak. Instead, Sun Simiao opened his mouth and asked, "Xiahou has the ability of Tao Zhugong, but why does he value this money so much?" ”

"Yes, searching the entire Chang'an City, I can't find anyone more slippery than you, tell me, why are you so entangled in this copper coin?" Li Shimin nodded, leaned back, looked at Xia Hongsheng and said.

Xia Hongsheng smiled and said, "Your Majesty, Daoist Sun, Fei Sheng is entangled in this money. Since Weichen left Luanzhou, he has cooked new tea, made sugar, brewed liquor, and burned glass...... Isn't that a dividend of tens of thousands of dollars a year? Your Majesty, what Weichen values is not a copper plate in this mere area, what Weichen values is the rules behind it. ”

"Rules?" Li Shimin suddenly raised his eyes and asked.

"Yes, Your Majesty, it's a rule." Xia Hongsheng stood up and bowed again, and replied: "Your Majesty, the rules that Weichen said have been lacking for a long time, so there are countless people who hide their unique skills, only pass them on to their descendants, not outsiders, and would rather bring them into the coffin than let the world know about them." It is precisely because of the lack of such rules that people stick to the secret skills in their hands one by one, unwilling to take them out and spread them, and unwilling to let the people of the world benefit. Your Majesty, how many skills have been lost throughout the ages, and why have these skills been lost? Naturally, because no one will meet again. And why doesn't anyone do? Guy cherishes the broom and never wants to pass it on to outsiders, so that more people can learn it. And the reason for this is nothing more than another sharp word. Only if you know, you can guarantee that you will benefit from it, and if two people know, this benefit will be reduced by half. If more people know about it, everyone in the world will know it, and naturally they will not be able to rely on this thing to make a profit. Therefore, those who hold a certain skill never want more people to know about this skill, which leads to fewer and fewer people who will know, and if there is a slight accident, the skill cannot be passed on, and then it is lost. ”

As soon as the words fell, Li Shimin was about to speak, but suddenly heard Sun Simiao sigh, and Imperial Physician He also looked sorry, shook his head and sighed.

Li Shimin looked at the two of them and asked, "Daochang Sun, why is Imperial Doctor He sighing?" ”

The two glanced at each other, only to see Imperial Physician He bow and salute, and replied: "Back to Your Majesty, Weichen listened to Xiahou's words and thought of some medical things. For most of the past six months, His Majesty has taken pity on the people and ordered Weichen to assist Sun Daochang in compiling the world's medical prescriptions for the benefit of all the people in the world. Weichen and Sun Daochang collected ancient books everywhere, searched for medical books, and found many diseases today. However, Weichen and Sun Daochang consulted countless medical books, and vented many prescriptions, but they didn't say that they had found it, but they had never heard of it. There are even some recipes on it, in order to prevent people from misappropriating them, deliberately writing the wrong prescriptions, replacing them with other similar medicinal materials, or giving those medicinal materials a false name, as for what kind of medicinal materials the real name is, I am afraid that only the formulator himself knows. All these have caused countless good remedies to be lost, and countless symptoms have no cure. Guy refused to spread the word at the beginning, just as Xiahou said, he would rather bring it into the coffin than let others know. Wei Chen just listened to Xiahou's words, and it was these things that he thought of, so he sighed. Thinking about it, Sun Daochang should have thought of one thing with Weichen. ”

"Not bad." Sun Simiao nodded, sighed, and said: "Take this malaria as an example, if it weren't for Xiahou Gaoyi, who sacrificed the method, I'm afraid the world wouldn't know that there is still a cure for this malaria, and the effect is excellent." But how much can the world be like Xiahou's righteous people? More people are holding Fang Zi in their own hands for profit, but they are unwilling to contribute. ”

"It's a pity that the skills are lost." Li Shimin also said: "I watched Xiahou's "Romance of the Three Kingdoms" before, and saw that Zhuge burned the rattan armor army in it, and I was very curious about its rattan armor, so I checked the classics and did find some words about the rattan armor, but it was only a few words. It can be seen that there was indeed this rattan armor at that time, but now it is lost, but it cannot be used in my Tang Army. ”

"Yes, Your Majesty." Xia Hongsheng said: "We just lack a rule, a rule that allows the holders of those skills to take out their unique skills with peace of mind for everyone to learn and use for the people, a rule that can make them wish more people to learn those skills." We need a rule that will make it possible for the holder of his skills to make his skills known to the whole world, but the more people who will do it, the greater his benefits, and who will hide his secrets? On the contrary, they will not get anything by hiding their smuggling, but they can get more benefits by taking them out, so naturally they do not have to worry about hiding their smuggling, and they do not have to worry about the loss of those skills if no one learns those skills. ”

Li Shimin's eyes lit up: "What rules?" ”

"Patent!" Xia Hongsheng explained to Li Shimin: "Exclusive rights! The court established a law to determine from the level of the law that whoever invented a skill, or a prescription, or any other utensil, had the exclusive right to such a thing. This exclusive right is protected by the laws of the Tang Dynasty, and others cannot infringe on its exclusive right. Those who infringe on the patents of others shall be punished in accordance with the law, and those who invent something very useful shall be rewarded. It is a legal rule that anyone other than the proprietor who wants to use this technique must obtain the consent of the patent holder and provide a certain amount of remuneration to the patent holder as a patent fee. Datang's laws punish those who maliciously infringe, impersonate, or coerce the use of patents to protect the interests of patent owners. In this way, those who hold a certain technology, in order to make their unique skills protected by the laws of the Tang Dynasty, need to apply for a patent from the imperial court. Only when the imperial court approves and approves his patent will he enjoy the right to the patent, and his skills or things will be protected by the laws of the Tang Dynasty. In this way, the imperial court has an understanding and record of these unique skills, and knows that there are these skills. Some of them have a major effect on the people and the country, and the imperial court can buy the right to patents, and then reward and promote them for the benefit of the people. In this way, the imperial court has an understanding of these things of the people, and at the same time, their rights are protected. If other people want to use, or give royalties, or other benefits, he can get greater benefits from them, so he will definitely no longer keep his skills private, and our Datang will also become more powerful, or richer, more convenient, or more advanced because of the promotion of these things! ”

Xia Hongsheng's words were very demagogic, and painted a picture of Li Shimin's endless emergence of various skills, which made Li Shimin's eyes brighter and brighter. (To be continued.) )
