"Quick, quick, you set up the stove." This is the eldest grandson's palace, and the two princesses can still do whatever they want, and after a while, they will make a mess of the queen's good palace, but a stove has also been set up.

It turned out that after the two princesses returned to the palace, they first went to Li Er's place, and when they arrived, Li Er was not there, so they heard from the little eunuch that their father was in the queen mother's place, so they led people all the way to the territory of the eldest grandson.

As a result, the world's biggest joke was born, and the eldest grandson's palace was robbed as if it had been robbed by the hands of the two princesses, which was miserable. What brocade and satin were thrown to the ground, this is to make room for the stove, and what calligraphy and paintings of the Han Dynasty Confucianism, the calligraphy and painting of the former Confucian, and the imitation calligraphy and painting of the Confucianism of the present Dynasty were also torn off from the wall, this is to avoid causing fire.

The two princesses said that Yang Heng said that this can prevent fires, and there can be no paper products, no cloth products, and no wood around the stove.

But fortunately, the two princesses did not demolish the house, but directly took a knife and saw and began to saw the lattice on the door, what kind of rosewood is this, what kind of rosewood, alas, it is a very precious wood anyway, Li Er can't name it, it was destroyed by the two princesses, Li Er has always gritted his teeth with hatred, "Yang Heng, you kid wait for me, see that I don't cure your crimes, you provoke the princess to come back and toss so much, fortunately, it's not in my palace, in the queen's place, I still have some face." ”

However, he watched the two princesses jumping up and down, and his heart ached again, "Come on, don't help the princess sawing down that place." A few little eunuchs walked forward, took the knife and saw from the princess's hand and helped saw the lattice flute, and every time he sawed it, he had to look at Li Er, he was also afraid that Li Er would be angry, the princess didn't understand, but they understood, there were no cheap things in the palace.

"Look at what I'm doing, just do what the princess wants, well, slow down first, and show me the saw in your hand." "Your Majesty's life, Your Majesty's life." Li Er's stumbling frightened several eunuchs, thinking that Li Er was going to punish them.

"Whatever you ask for, I don't want to cure your sins, get up, and I just want to see the saw in your hand." As he spoke, Li Er took the knife and saw from a eunuch, "This is a saw, Lizhen, come on, why didn't my father listen to you about this thing." "Father, isn't this an ordinary saw, all the saws used in Yang Heng's house are this kind of saws." Li Lizhi was a little confused, why is his father interested in this saw, this is really a common appliance of Yang Heng's family, "Yuzhang, you come on." "Yes, Father, when my little mother used to play with us, sometimes I would use this kind of saw to see things, and we learned it, otherwise, my sister and I forgot to use the saw."

Yes, this Li Er asked the strings, in fact, Li Er's vision is good, this kind of saw is still Yang Heng after seeing the saw used by the uncle, he only began to build it, if you want to say this saw, the words can be long, how to say it, the child has no mother, it is a long story, when Yang Heng made the waterwheel, there were some components that needed a saw to be fine sawing, but Yang Heng saw the toothless and toothless saw that Uncle got out of nowhere, he was a little thundered, that's it, Uncle still took the saw as a baby, so, After the waterwheel was made, it was just erected on the water, and the first thing Yang Heng did was to make a grinder, the grinding wheel, naturally not the synthetic grinding wheel of later generations, and there are all kinds of materials, but now, Yang Heng's only choice is sandstone, after careful selection, Yang Heng chose several sandstone chips of different thicknesses, and then made a circle, and made a round hole in the middle, which is fixed the grinding wheel, after the power, and threw a few pieces, and then those good ones, After the friction between sandstone and sandstone, as well as the correction of the grinding wheel knife, there is a thick grinding wheel for grinding knives, and a thin grinding wheel for grinding saws, some people may say, how good it is to use a file, don't be so troublesome, but the saw made by Yang Heng is steely, and the file cannot be filed, after the grinding wheel is made, the knife and saw in Yang Heng's home are popularized, especially the aunts like it the most, so that when cooking, some harder wooden sticks are directly sawed with a saw knife.

But it is a grinding wheel, Yang Heng prohibits anyone from using it, even the uncle can't use it, it's too dangerous, if you're not careful, it's easy to break and hurt people, so Yang Heng will hide the grinding wheel after grinding things every time, and even warned Xiaoniang and others that they can't take it out to play.

Li Er looked at the knife and saw in his hand, and was even a little shocked, is this also supposed to be a very good tool, and it is an unprecedented tool. "Father, father, we can't set up a stove yet." Yu Zhang looked at Li Er in a daze, and asked coquettishly, but Li Lizhi was silent on the side, she also saw that this saw knife was unusual, she was regretting, why didn't she think of it before, this ordinary thing is also a good thing.

"Rack, rack, you go on." At this time, Li Er's teeth were bitten even harder, good you Yang Heng, you have such a good tool, and you don't give it to me, and you actually let the two princesses toss my queen.

To tell the truth, tossing the eldest grandson, this is not Yang Heng's idea, Yang Heng thought that the two princesses would toss Li Er's palace, in order to let the two princesses do this, Yang Heng has acted enough.

"Two princesses, this house is newly built, don't toss it, or let's put it up in the courtyard and try it." Yang Heng pretended to be pitiful and said, "No, just set it up in this house, otherwise how can we know the quality of this stove." "At first, Yang Heng was going to tear down the roof, but after thinking about it again, no, if the two princesses go back and don't tear down the roof, then it will be in vain, so it was changed to a lattice on the door.

And Yang Heng didn't expect that Li Er was here with the eldest grandson, and the two princesses didn't know whether they were the eldest grandson or Li Er's territory, but we had to cook and fry vegetables for our father to eat, this was their idea.
