"Tell me, what kind of things and what hunting are you taught, what's going on?" When Yang Heng and Yu Zhang and the others saw Li Er, before Yang Heng and the others saluted, Li Er was anxious first.

"What's going on?" Yang Heng didn't react at once, Li Er was so anxious, was it necessary? "Isn't it that I found that those craftsmen and old farmers are too stupid, so I just gave them the knowledge of these things, and even the knowledge of some changes in things, which is nothing?"

"It's nothing, that's what you heard from that Xiucai who wasn't Xiucai? You think I'm a fool! "Yes, is it necessary, isn't it just some knowledge of physics and chemistry, and it's not to hide what small actions you are doing behind your back, you are too much of a fuss, fortunately, Yang Heng is still prepared.

"Oh, that's what Your Majesty said, I don't know if Your Majesty has seen the ink scripture in Mozi, the minister just added some of his own understanding on this basis." Yang Heng said a little lightly, you can't panic at this time, panicked words will make Li Er even more suspicious, and even Yang Heng's tone still has a mocking meaning, it's a pity that no one has noticed such a good book for more than a thousand years.

"Huh!" Li Er was choked by Yang Heng for a while, but at this moment, Yu Zhang also fell into the ground, "Father, I seem to have seen that book in your study, but how can my brother-in-law make so many things?" Yu Zhang didn't care about thirty-seven twenty-one, but actually said that Li Er was coming, "I thought my father called us here, my brother-in-law is holding the ink scripture every day!" "Do you know what Lu said, Yang Heng got the Ink Sutra. It was only collected at the homes of some veterans in the countryside this time. If you go late. Maybe it will be burned as firewood and grass, when Yang Heng found out that these rotten bamboos turned out to be the Ink Sutra, he was a little ecstatic, he was really going to fall asleep, there was a pillow, you must know that this Ink Sutra is mathematics, and there is everything in the grid, and even the small hole imaging was first proposed on the Ink Sutra. Although Yang Heng didn't understand this scroll of the Ink Sutra very well, he knew that this was the Ink Sutra, but the most fortunate thing was that Yang Heng had seen a tool book for explaining the characters in his previous life, and he bought it for the child at that time, in order to let the child learn, he had to read it himself, but the child didn't read it, but he read the book of the Ink Sutra, so he still knew most of the words in this scroll of the Ink Sutra. It's no problem to fool Li Er now.

For these ancient oracle bone inscriptions, there are still very few things that Datang can explain. But because of this, maybe Yang Heng caused some trouble for himself, because finally someone could debate with him openly for some things.

"I'll settle accounts with you later, come here, bring the ink scripture." Li Erbai glanced at Yu Zhang, and then asked people to take the ink scripture.

"Your Majesty, is this to be given to the minister, thank the lord Longen." Yang Heng knew that Lu Dao was going to test him, but he pretended to be stupid, and then knelt down to thank him.

"Well, this, I, you, you give it to me, I don't want to give it to you, this is the only book in my palace, come, you explain it to me, and see where the content you said is?"

"Alas, the minister thinks that His Majesty wants to give it to the minister, you must know that the ink scripture there is incomplete, if Your Majesty gives this book to the minister, the minister is grateful, otherwise, Your Majesty, you will give it to the minister to go back and copy it."

"Then explain the meaning of this sentence to me first." This is really profound, it turned out to be oracle bones, but it was picked in Yang Heng's heart.

"The shadow is down, and there is a long shadow at noon, saying that it is at the end. …… In the near and far, there is an end, reflected in the light, so the photo library also. "Your Majesty, this doesn't need to be explained by the minister, and the minister can't say it clearly, but the minister can show it to His Majesty."

What does this mean, it is the part of the small hole image, when Yang Heng read it again, he was happy, "Your Majesty, please find a dark room, and then find a thin plate for the minister, and a candle, the minister will show it to His Majesty, you can also follow, this is a part that I have not touched, and it is also a part that is incomplete in my place, and it happens to be completed here under Your Majesty." ”

The dark room is naturally easy to find, but if there is none, Li Er will also ask the eunuchs and palace maids to quickly arrange a dark room. "Your Majesty, what are you doing here, the concubine is late." "I've seen the queen mother (Niangniang)." All the people saluted in unison.

"Okay, Xuewen, you're so bold!" Yes, what's the matter, this Li Er didn't even have time to train when he saw Yang Heng, even the eldest grandson, fortunately, he let everyone train after the ceremony.

"You two still know how to come back!" What's the matter, it's not pleasing to the eye when you see anyone, "The little lady is here, let Bengong take a look, it's really getting more and more beautiful." "Yes, after all, there is one who has been praised, but what kind of praise are you, how do you let the little lady answer, is the answer average, or is it not as beautiful as the mother.

"The little lady has seen the mother." Okay, then let's give you another salute, "Come, come, let Bengong see," as he spoke, he took off a bracelet from his hand and put it on his wrist for the little lady, what is this phenomenon, this is your daughter-in-law, how can she be so polite.

Oh, by the way, the eunuch in front said that Li Er was very happy, and the natural purpose was not to reprimand Yang Heng, so since he was reprimanded, he had to express his goodwill like this and not let Yang Heng be suspicious.

"Mother, mother, brother-in-law wants to show us something interesting, you can go in with us and have a look." "Well, okay, I'll go in and have a look, too." It seems to be very reluctant, but her heart is still itchy, you must know that Lu Dao is not only Li Er was surprised when he heard it, but even the eldest grandson was also very curious, how could Yang Heng know so many things about Lu Dao, so isn't the live demonstration just to see what kind of ability this is?

"Your Majesty, Niangniang, the dark room is ready, and the cardboard and candles are also ready, do you want to go in now." There are eunuchs who come to report, it seems that there are no dark rooms in the palace, or are the dark rooms some secret places? This is just a temporary preparation, or the requirements are too high, and there is no light in it, mainly because he is afraid that the demonstration will fail.

"Your Majesty, wait a minute, let the minister drill a hole in this cardboard," because it is cardboard, so the hole is very easy to drill, as long as a thin round wooden strip is used to drill a small hole of one millimeter in the middle of the cardboard, "You see Your Majesty, the minister drilled such a small hole in this cardboard, and then it is time to witness the miracle." When Yang Heng said that he was ready, everyone walked into the dark room, and at this time there were already candles lit inside.

Yang Heng looked around, "You, come here, hold the candle, I say stop, you stop." Yang Heng commanded a palace maid to carry a candle, and then came to a wall, which was a smooth wall.

If it was in a previous life, some people might say, I took off my pants, you just let me see this, but at this time, Li Er didn't understand these humors, even if he did, he didn't dare to say, to know how many girls there were in Lu Dao.

"Look at Your Majesty, a miracle has happened." As he spoke, Yang Heng put the cardboard in the middle of the candle and the wall, and put the small hole parallel to the candle flame, and then an inverted candle flame appeared on the wall, how can this be seen, someone walks, naturally the flame will swing with the wind, and naturally on the wall, you can see an upside-down flame head swinging with the wind. Then Yang Heng moved the cardboard back and forth, and saw that the flames on the wall would be big and small.

"Oh!" Everyone let out a sound of exclamation, this is really a miracle, could it be that Yang Heng will not be able to do any magic, or will he be able to do Taoism. Just such a small hole imaging shocked everyone.

"Okay, Your Majesty, the minister's demonstration is finished, can we go out?" For a long time, Li Er had already closed his mouth, he was so surprised that Yang Heng was able to turn the shadow of the candle upside down on the wall. (To be continued......)
