"Xuewen, is this the painting pod in "Han Feizi, the Foreign Prince Says Left"?" After everyone came out to sit down, the first thing Li Er said turned out to be such a sentence.

But how could Yang Heng have seen Han Feizi, don't say that the foreign reserve says left, or the foreign reserve says right, don't say that there is really a foreign reserve saying right.

"Your Majesty, the minister is lonely and unheard, the minister only knows that there is such a book as Han Feizi, but there is no one there, naturally I don't know what the foreign prince said left, I don't know what to say left, and I don't know what painting pods are, I don't know if Your Majesty can let the minister see what Han Feizi's foreign prince said left?"

"Well, don't read this, let me explain it to you." Finally, Li Er has a knowledge that Yang Heng doesn't know, and it's not good to show off, if Yang Heng is allowed to see it, Yang Heng will understand it when he looks at it again, doesn't it seem that he is even more incompetent, but he thought wrong, since there was such knowledge in ancient times, but at this time there was no more, so it proves that these things have been lost, just like Mozi, although some bamboo slips have been handed down, but some explanations have been lost.

"The guest has painted pods for Zhou Jun, and it has been completed in three years, and the monarch has a ...... Zhou Jun did it, and when he saw it, he became a dragon, snake, bird, beast, chariot and horse, and everything was ready. Li Er was frustrated, isn't this just a slide in ancient times, but seeing that Li Er is so happy, it's better not to mess with him.

"This, Your Majesty, the minister really doesn't know what the painting pod is, can Your Majesty explain it to the minister," "Yes, yes, father, there is something that my brother-in-law doesn't know, you can tell me." What does this mean, maybe my brother-in-law can make it. Yu Zhang was anxious on the side, and the eldest grandson saw Yu Zhang like this on the side. Shook his head helplessly, it seems that this daughter has completely fallen, and it is too embarrassing for the royal family, and there will be two princesses marrying a person with no background.

Li Er was also a little displeased when he saw Yu Zhang like this, but what could he do. The princesses of the Tang Dynasty are all very individual, if they don't agree, I don't know what Yuzhang will do. It's better to go with the flow, otherwise it will be even more humiliating.

If you want to say that Li Er is not doing well, it is that the two of them do not know how to educate their children, which makes it clear that their sons and daughters are all very individual. But it's incredible.

"Ahem." Turning his face and seeing Yang Heng's eyes with a desire to learn, Li Er's unhappiness just now disappeared without a trace, and then it turned out to be pride, and even an indescribable emotion, "Okay, let me explain it to you, just talk about Zhou Tianzi." I heard that there is an artist among the people who is very good at drawing. So he called him to the palace to ask this painter to paint for him, and it took three years to paint, but it looked like a pod-like transparent thing, but there were pools of paint on it, so Zhou Tianzi was unhappy...... This is a story that Han Feizi said inside and outside, at first I thought it was a joke, how could it be, but since I watched the one you did in the dark room. "Back to Your Majesty, it's a demonstration." "Well, as you can see from your demo, is this similar to this?"

"Yes, Your Majesty, listening to your explanation, it should be a tired thing, it seems that the minister is lonely and unheard, and there is a record of this phenomenon of light that is still early, but the minister can't draw such a pod, if it is a bigger thing, the minister can let the craftsmen draw it, but there are still some problems that need to be solved."

Yang Heng is naturally talking about movies, but movies really have a lot of problems to solve, although light can be solved, this can be explained from this painting pod, as long as the sun is full every day, even make some small holes in the house, and then choose the appropriate holes according to the hour, and the painting, you only need to paint on the glass, you can see some active pictures.

It's not that Yang Heng hasn't considered the movie, but he hasn't figured out how to solve the light source, but the ancestors have already had a way to solve it, and even the paintings have been drawn, not only not to say that the ancestors are really powerful, but the descendants are too uncompetitive, or because of the secrecy of the skills, in the end, only the text is recorded, and the actual thing has been lost.

"Since there is a problem, then needless to say, don't you have anything else to say, such as your Yang number?" It seems that Li Er is still thinking about this number, "This, Your Majesty, don't you think it's a bit complicated for us to use words to represent these numbers, and it's hard to remember, especially when writing big numbers, what a big piece of paper it will be, even bookkeeping is also very difficult, isn't it, and the minister's uncle knows carpentry, but when he does carpentry, without a simple number, it is difficult to make the same thing, so the minister thought about it, painted and painted, and suddenly, the minister made a discovery!" Yang Heng was like telling a story, talking, talking, and suddenly stopped his words.

"What, what did you find?" Sure enough, Li Er was attracted, what does this have to do with thinking, thinking, painting, painting.

"Because the minister suddenly found that the minister drew some symbols on the ground, there were as many as ten, and there was no one identical, so the minister considered, can you use these ten numbers to represent ten numbers, at first the minister used the number zero as ten, but when the count to ten, he found that it was a little inappropriate to twenty or thirty, so the minister thought again, thought, this is how to come out, there is no zero in my numbers, if we are counting, put zero in the first place, Isn't that more rigorous, for example, there is a fan in your majesty's hand, and there is no fan in the minister's hand, so can it be said that there are zero fans in the minister's hand, and one in the front, zero in the back, you can form ten, the following is twenty or thirty, Your Majesty, you see, this is not simple, so the minister made use of the number in this way, and the minister's family has also learned this number, in a few years of practice, the minister's home is still good, and the minister has also taught the craftsmen in the mountains. ”

This nonsense, but Yang Heng is tired, believe it or not, anyway, you are not an expert in mathematics, how can you know that the creation of this number is not so simple.

"Well, well, I'll stop believing you, even if you pass the test, if I find out that you lied to me, then I will really blame you."

Okay, I finally passed the test, Yang Heng secretly breathed a sigh of relief in his heart, and even secretly thanked the old ancestor named Han Feizi in his heart, thank you very much, it was your story that made me pass, otherwise don't talk about making up numbers, it was Li Er who asked Yang Heng to explain how he could know some of the words on Mozi, and he couldn't explain it.

"No, I almost fooled you through." Suddenly, Li Er remembered something again, and Yang Heng was so frightened that he trembled, if you are finished, I will definitely not tell you that I am here through time.

"Your Majesty, there's nothing, but the ministers have explained it to you!" "Confessed? Then where did your hunting theory come about, that is, I am also my archer master and told me, you shoot arrows, you have to shoot away in front of the people, and how do you understand so much, what is the amount of advance, what fruit fell on the head, why didn't you smash you stupid? ”

This, Yang Heng breathed a sigh of relief, and saw that I made it up for you, "Your Majesty, this, it is really a matter of the minister's thinking, you know, the minister has opened up the wilderness in the countryside, especially in the early days, there is no output in the field, and the minister has to hunt to make a living, and at first the minister could not hunt when he hunted the prey of sports." "That, you're too good at making it up, if you can't fight, you'll starve to death early," the minister has been studying and studying, and finally found out that the place where the minister hit was actually the place where the prey was just now, and then the minister thought, the prey is also moving, and the stone thrown by the minister is also moving, and the place where the natural minister's stone is aimed at is the place where the prey was just now, because both sides are moving......"
