But Li Hua is indeed half an outlier, and after a long time of "boldly questioning and carefully verifying", he shook his head: "Well, the master has had, and since the disciple is aware of it, he should naturally speak out about his mistakes. As for 'taking a path of one's own', this is nonsense, the monarch has had it, and it is just to say that it is wrong, why go out behind the door. ”

That night, Guo Dalu didn't have time to teach the children, so he told them to study on their own and talk with Li Hua at night under the torch.

Although Li Hua is a square person, he is not stupid, you must know that he has studied hard for more than ten years, and if he can be a teacher in the county school, he will definitely not be a stupid person, and he soon found that although Guo Dalu's stomach is full of strange knowledge taught by the old people in the mountains, he knows nothing about common sense.

But Li Hua was soon relieved, his little senior brother, followed the old man in the mountain to live in Fengshen Mountain since he was a child, far away from the people, so he didn't know anything about the world.

Li Hua thought about it, picked out some common sense that everyone in the world knows, and slowly told Guo Dalu to listen, such as the reign of the Holy Son of Heaven today, the people are in the Ying Dynasty, the country and the people are safe, there are three princes, the prince is diligent and loves the people, and now he is supervising state affairs, the second prince is heroic and extraordinary, conquering the four yi, and winning great military exploits, but unfortunately the second prince was ordered to conquer the South Vietnamese barbarians a few years ago, but he was defeated, his subordinates mutinied, and even suffered a big defeat, and he was seriously injured――

What Li Hua said is actually the "basic knowledge" of the Great Li Dynasty, which is the common sense taught by the masters when the children are enlightened today, and now Guo Dalu deliberately opens a small stove alone, Guo Dalu silently remembers in his heart, in fact, he is a little disapproving, because in the "history" that Li Hua said, the saints of all dynasties have been assisted by the gods, for example, the founding ancestor, it was with the help of the Nine Heavens Xuannu that he defeated the Siyi. Since then, the monarchs of all dynasties have also received the help of different immortals, and there have been several kings who have become immortals and attained the Tao by themselves because of their great achievements.

Guo Dalu laughed secretly in his heart, these things are actually made up by the emperor Lao'er in order to show his divine authority to fool the people, in fact, when the people's wisdom was not opened, there were similar "histories" in ancient and modern China and abroad, and to put it bluntly, it was just one sentence - to scare the people.

Guo Dalu sneered in his heart, if there are really immortals in this world, then why do the immortals not keep out the endless white rice, and why do they let the people all over the world, including Houlong Village, go hungry and wear rags? Hmph, there has never been a savior in this world and it does not rely on the immortal emperor, and it is up to us to create the happiness of mankind.

However, Guo Dalu also learned from Li Hua's mouth that the Great Li Dynasty was a very large country, riding a horse from the northernmost point to the southernmost point, it would take several months, and the Siyi Dynasty respected the Great Li Dynasty, but in the northernmost desert, there was the Hu tribe, which established a Golden Horde, which was not civilized, and would violate the boundary from time to time, and the Great Li Dynasty fought for thousands of years.

In short, the Great Li Dynasty was rich in the four seas, the four Yi guests, all the countries came to the dynasty, and the whole world was the king's land, and within the four seas, all were kings' ministers.

Guo Dalu pondered in his heart, how to listen and listen, this big Li Dynasty that he crossed over is almost the same as the ancient **** of another time and space, and even in Li Hua's description, even the geographical environment is almost the same, and there are big rivers in the border, but one is called Tongtian River and the other is called Daqing River.

The only difference is that every few hundred years in the **** history of the original time and space, the dynasty will be changed, and in the Great Li Dynasty, since Taizu dominated the world, it has continued to this day, hanging for 2,126 years, and it can really be called an iron-beaten country - of course, Li Hua's explanation for this is that the Holy Son of Heaven has the help of the gods, although occasionally there is a small rebellion in the territory, but as long as the gods make a move, it will be immediately quelled.

Guo Dalu knew that all history was whitewashed by the rulers, and it was really a detour to learn the truth about this dynasty from the orthodox history books, so he soon lost interest in Li Hua's basic knowledge education, and the two turned to talk about "science".

Li Hua said: "Little Senior Brother, I came to Houlong Village to visit you, and I originally came for printing. ”

Guo Dalu smiled: "I understand what you want to see." He got up and turned out a few pieces of wax paper left after the printing method and punctuation method: "Senior Brother Li, the secret of printing is here, this wax paper was passed on to me by the master, with ink, iron pens, and iron plates, it can be printed very conveniently." ”

Li Hua carefully examined the wax paper: "This wax paper is obviously painted with wax on a very thin paper, and then engraved with an iron pen, and the wax is completely removed, covered with ink, penetrates the handwriting, and is printed on the paper behind it, which becomes the printed text." This method is much simpler than engraving or movable type printing. As far as I know, a clever craftsman engraving plate, a plate takes more than ten days, carved a wrong word, the whole version will be invalidated. Movable type printing also needs to do a good job of clay mold in advance, and new words must be opened in a new mold. And this wax paper, written and printed, is convenient and fast. Especially in the midst of large armies, when marching and fighting, tens of thousands of official documents can be printed at once through wax paper. ”

Guo Dalu nodded and said: "Yes, the biggest advantage of the wax paper printing method is convenience. However, although I have now prepared ink, I only have these few sheets of wax paper, which were passed down to me by my master, and I don't know how to make wax paper. ”

Li Hua muttered: "The key to wax paper is that the paper should be thin, and the paper can be covered with wax, I know several paper-making workshops in Fucheng, and I can ask their craftsmen if they can make similar thin paper." ”

Guo Dalu clapped his hands: "Okay, then it's troublesome Senior Brother Li." ”

Li Hua was stunned: "Little senior brother, aren't you worried about the spread of your master's wax paper printing skills?"

Guo Dalu said with a smile: "What do I have to worry about, the master has already said when he passed on my knowledge, and hopes that I will spread his science as widely as possible, his various skills, the more people who know, the more people who learn, the better, but it is not hidden in his own cave and moldy." ”

Li Hua said with a smile: "Our master, the old man in the mountain, is really an immortal sage, but I hate that I, an anonymous disciple, have no chance to meet his old man." ”

Guo Dalu said: "The master once said that the process of his knowledge transmission is also a process of re-learning by himself. His knowledge is not always right, if others can find the problems and solve them in the process of learning, then he is willing to worship others as teachers, this is endless learning. ”

Guo Dalu said excitedly, and suddenly asked: "Senior Brother Li, who do you think is the stupidest, master, me, and you?"

Li Hua was stunned: "Do you still need to ask? Among the three of us, naturally the master is the smartest, you are the second, and I am the stupidest." ”

Guo Dalu shook his head and said: "No, no, but the master said that he is the stupidest!"

Guo Dalu picked up a piece of charcoal from the stove and drew three circles of different sizes on the ground, he pointed to the circle and said: "This circle is like the knowledge that the master, me, and you have, and outside the circle is our unsolved knowledge." Senior Brother Li, look at it, Master, me and you, who has come into contact with the most unsolved knowledge?"

Li Hua gestured to three circles of different sizes, and suddenly jumped up: "I understand! I understand! The master has the greatest knowledge, the bigger his circle is, and the more places he comes into contact with the unsolved knowledge next to him, the master knows that he doesn't know knowledge, much more than us, so he said that he is the stupidest!"

Guo Dalu threw the charcoal in his hand, clapped his hands and said: "That's right, how stupid the world is, always like to hold his little bit of superficial knowledge and think it is a treasure, keep it secret, and hate to pass it on to his children and grandchildren from generation to generation, but he doesn't understand that knowledge needs to be exchanged, and only in exchanges and collisions can knowledge become clearer and clearer, and can it move forward." The more you learn, the more you realize that you are ignorant, and resting on your laurels is the most stupid thing to do. I hope that I can spread science in this world on behalf of my master, and the more people who learn it, the better. ”

"What is a mere wax paper printing, I still have lead movable type printing and color ink printing here, I only hope that this kind of printing technology will spread as widely as possible, and I welcome that clever and talented people to improve these printing techniques, so that more and more exquisite books can enter thousands of households at a cheaper price, so that the children in Houlong Village can also have a full shelf of books!"

Li Hua was dizzy, a shelf full of books? He is a person who loves books very much, but he only collects a box of books, many of which he copied one by one, and in the wish of Guo Dalu, the little brother, even the little doll in the countryside can have their own book house!

But Li Hua knows that Guo Dalu is not bragging, because only one wax paper printing technology can greatly reduce the cost of books, if Guo Dalu really has all kinds of magical printing techniques as he said, so that the world's reading seeds can afford to buy books, and it is not a lie.

Li Hua praised: "Senior Brother Guo has such great ambitions, it is really a blessing for the people of the world. It will take time for this kind of novel printing invention to take time, but I think that I can use the wax paper given by the master to print the "Three Character Classic" first, and if I can make the "Three Character Classic" compiled by the master become a must-read for the enlightenment of the children of my Great Li Dynasty, it can be regarded as my senior brother and I have made a name for the master. ”

Guo Dalu nodded: "Fame or not, the master doesn't value it, but the master has indeed compiled a few books suitable for children to read, in addition to the "Three Character Classic", there are also "Hundred Family Names" and "Thousand Character Text", which contain various small stories such as astronomy and geography, human ethics and righteousness, loyalty, filial piety and righteousness, which are not only catchy to read, but also allow children to understand what benevolence, righteousness, sincerity, respect and filial piety are imperceptibly. ”
