"Learn literature, is this the painted pod in "Han Feizi, Foreign Crown Telling Zuo"?" After everyone came out to sit down, the first sentence Li Er said was actually like this.

But how could Yang Heng have seen Han Feizi? Don’t say that the foreign reserve said the left, or the foreign reserve said the right, but don’t say that there is really the foreign reserve saying the right.

"Your Majesty, I am ignorant. I only know that there is a book like Han Feizi, but I don't have it. Naturally, I don't know what the foreign throne said, and I don't know what the foreign throne said, "I don't know what the painted pods are. I wonder if Your Majesty can let me see what the foreign throne said, Han Feizi's foreign throne said, "

"You should not read this, let me tell you a little." Finally, Li Er had a knowledge that Yang Heng didn't know, and he didn't show off his appearance. If Yang Heng saw it, Yang Heng would understand it after seeing it again. It wouldn't it seem even more incompetent, but he was wrong. Since there was this knowledge in ancient times, it was gone at this time, then it proved that these things had been lost, just like Mo Zi. Although some bamboo slips were passed down, some explanations were lost.

"The guest painted a pod for Zhou Jun, and it was made in three years. You looked at it... Zhou Jun was doing it, and saw it, and all things were ready." Li Er raised his back with excitement. Isn't this an ancient slide? But seeing Li Er was so happy, it would be better not to mess with him.

"This, Your Majesty, I really don't know what kind of painted pods you can explain to me," "Yes, yes, my father, there are things that my brother-in-law doesn't know. Tell me, what does this mean? Maybe my brother-in-law can do it." Yu Zhang was anxious, and Changsun saw Yu Zhang like this. He shook his head helplessly. It seemed that this daughter had completely fallen. It was a sin that was too embarrassing to the royal family. It happened that two princesses married a person without background.

Li Er was a little displeased when he saw Yu Zhang like this, but what could he do? The princesses of the Tang Dynasty were very unique. If they didn't agree, they didn't know what Yu Zhang would do. It would be better to let it go. Otherwise, they would be even more embarrassing.

If Li Er did something bad, it was that the couple couldn't educate their children. This was awesome for their sons and daughters.

"Well," turned his face and saw Yang Heng's eyes with desire for knowledge. Li Er's displeasure just now disappeared. Then he was proud, even an indescribable feeling. "Okay, let me explain it to you, and I will say that Emperor Zhou is the emperor. I heard that there is an artist in the folk who is very good at painting, so I called him to the palace to ask the painter to draw for him. It took three years to draw it. But it looked like a transparent thing like a pod, but there were a pool of paint on it. So Emperor Zhou was unhappy... This is a story about the Left Zhong in Han Feizi's inside and outside the store. At first, I thought it was just a joke, how could it be, but since I watched the performance you did in the dark room." "Go back to Your Majesty, it's a demonstration." "Yes, the demonstration. From your demonstration, it can be seen that this is similar to this one?"

"Yes, your majesty, you should be tired after your explanation. It seems that I am ignorant and have a record of this phenomenon of light that is still early. But I don't know how to draw such pods. If you say something bigger, I can let the craftsmen draw it, but there are still some problems that need to be solved."

Yang Heng naturally talks about movies, but movies really have many problems to solve. Although it can be solved by just one can be explained from this painted pod. Every day, when there is plenty of sunshine, you even make some small holes in the house, and then choose appropriate holes according to the time. When painting, you only need to draw on glass to watch some active movies.

It’s not that Yang Heng hadn’t considered the movie, but he never thought about how to solve the problem of the light source. But the ancestors had already had a solution and even painted the paintings. Not only did the ancestors really be very powerful, but the descendants were too unsatisfied, or because of the confidentiality of their skills, they were only recorded in the text, and the actual things had been lost.

"Since there is a problem, there is no need to say anything else. What is your Yang number?" It seems that Li Er is still thinking about this number. "This, Your Majesty, you don't realize that we use words to express these numbers is a bit complicated, and it is difficult to remember. Especially when writing big numbers, it would be so big that it would have to be written, even if it was difficult to keep accounts, it was also difficult, but when he was doing carpenters, it would be difficult to make the same thing without a simple number. So I thought about it, draw and draw, and suddenly, I made a discovery!" Yang Heng was like telling a story, talking and suddenly stopped his words.

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

"Because I suddenly discovered that I had drawn some symbols on the ground, and there were as many as ten, and there was no duplicate, so I thought, could I use these ten numbers to represent ten numbers? At first, I used zero as ten, but when I counted ten, I found that it was not suitable when I reached twenty-thirty. So I thought again, and then I thought, I didn't think of this number, which was zero in my numbers. If we were counting, give zero to zero.

If you put it first, does it seem more rigorous? For example, if Your Majesty has a fan in his hand, but I don't have one, then can I say that I have zero fans in my hand, and once in front and zero in the back, I can form ten, and the bottom is twenty-thirty. Your Majesty, you see, isn't this simple? So I used the numbers in this way, and my family has also learned this number. In the years of practice, my family has used it well, so I have taught it to the craftsmen in the mountains."

This clue made Yang Heng exhausted. Do you believe it or not? Anyway, you are not an expert who specializes in mathematics. How can you know that the creation of this number is not that simple?

"Well, okay, I'll stop believing you. Even if you pass the test, if you find that you have lie to me, I will really blame you."

Okay, finally passed the test. Yang Heng secretly breathed a sigh of relief in his heart, and even secretly thanked the ancestor named Han Feizi in his heart. Thank you, it was your story that made me pass the test. Otherwise, let alone make up numbers, even Li Er asked Yang Heng to explain how he could understand some of the words on Mozi, but he couldn't explain it.

"It's not right, I almost let you get away with it." Suddenly, Li Er remembered something again, and Yang Heng was so scared that he shivered. Are you finished? I will definitely not tell you that I came from time to time.

"Your Majesty, there's nothing left, I've explained it to you!" "I've explained it all? Then how did your hunting theory come from? Even I am my archer and archer tell me, "You shoot arrows and shoot the front of the person walking, why do you understand so much? What else is there to measure in advance? What fruit fell on your head, why didn't you smash it stupid?"
