"Hurry, hurry up, you guys set up the stove." This is Changsun's palace. The two princesses can still do whatever they want. After a while, they made a mess of a good palace of the queen, but a stove was also set up.

It turned out that after the two princesses returned to the palace, they first went to Li Er's place. When they arrived, they saw that Li Er was not there, so they heard from the little eunuch that his father was with his mother, so they led people all the way to Changsun's territory. This time, they happened to block Li Er and Changsun, so let's perform in front of these two people.

So, the world's biggest joke came about. Changsun's palace was like being robbed by the hands of two princesses. This was miserable. Brocade and satin were thrown all over the floor. This was to set up a place to set up a stove, and there were also calligraphy and paintings of the great scholars of the Han Dynasty, calligraphy and paintings of the great scholars of the previous dynasty, and imitation calligraphy and paintings of the great scholars of the current dynasty, which were also torn off the wall to avoid causing fire.

The two princesses said that Yang Heng said that this can prevent fires. There should be no paper products, cloth products, and wood around the furnace tube.

Fortunately, the two princesses did not demolish the house, but instead took a knife saw and started to saw the lattice on the door. This is some rosewood or red sandalwood. Alas, it is a very precious wood anyway, and Li Er couldn't call it a name, but was actually destroyed by the two princesses. Li Er kept gritting his teeth with hatred, "Yang Heng, you wait for me, see if I don't cure you, you provoke the princess to come back and make trouble. Fortunately, it's not in my palace, but in the queen, I still have some face."

However, he saw the two princesses jumping up and down, and felt heartbroken again, "Come here, why don't you help the princess cut that place?" Several eunuchs walked forward, took the knife saw from the princess and helped to cut the lattice. And every time they saw it, they had to look at Li Er. He was also afraid that Li Er would get angry. The princess didn't understand, but they understood that there was no cheap thing in the palace.

"See what I do, just do it as the princess wishes. Oh, let me see the saw on your hand." "Your Majesty, your Majesty." Li Er's stuttering frightened several eunuchs, thinking that Li Er wanted to punish them.

"What are you asking for? I'm not going to cure your sins. I'm just going to see the saw on your hands." As he said, Li Er took the knife saw from a eunuch. "This is a saw, Lizhi, why didn't the father listen to you?" "Father, this is not a very ordinary saw? This is all used in Yang Heng's house." Li Lizhi was a little confused. Why was his father interested in this saw? It's really a common utensil in Yang Heng's family, "Yu Zhang, you said." "It's Ao, Father, when my mother played with us, she sometimes used this kind of saw to see things, so we learned it. Otherwise, my sister and I forgot to use a saw."

OK, Li Er had a question string. Actually, Li Er had a good attitude. This kind of saw was created by Yang Heng after seeing the saw used by his uncle. If you want to say this saw, it was so long. What do you think? The child is not a mother, and it was a long story. When Yang Heng made a water truck, some components needed a saw for fine sawing. But after Yang Heng saw the saw with toothlessness that his uncle got, he was a little stuck. That's it. The uncle also used the saw as a treasure. So, after the water truck was made, it was just erected on the water. The first thing Yang Heng did was to make a grinder. Grinding wheel, which was naturally not a synthetic grinding wheel of later generations, and there were all kinds of materials. But now, Yang Heng

The only choice is sandstone. After careful selection, Yang Heng chose several sandstone flakes of different thicknesses, and then made a round hole in the middle. This is the fixing of the grinding wheel. After the power was put on, a few pieces were broken. The next ones were good. After the friction between the sandstone and the sandstone and the correction of the grinding wheel knife, there were thick grinding wheels for sharpening tools and thin grinding wheels. Some people might say that it would be great to use a file, so don't be so troublesome, but the saw made by Yang Heng is steely and cannot be filed with a file. After the grinding wheel was made, the knife saws at Yang Heng's home became popular, especially the aunts liked it the most. When cooking, some harder wooden sticks were directly sawed with a saw knife.

But even the grinding wheel is forbidden by Yang Heng, even if he is uncle, he cannot use it. This is too dangerous. If he is not careful, it will easily break and hurt people. Therefore, Yang Heng would hide the grinding wheel after grinding things, and even warned Xiaoniang and others not to take it out to play.

Li Er was even shocked when he looked at the saw in his hand. Should this be the same good tool, and it was an unprecedented tool. "Father, Father, can we still set up a stove?" Yu Zhang looked at Li Er in a daze and asked coquettishly, but Li Lizhi was not speaking any more. She also saw that the saw was extraordinary. She regretted that she had never thought of it before. This ordinary thing was also a good thing.

"Stack, stand, you guys continue." At this time, Li Er's teeth were even more ruthless. You Yang Heng, you have such a good tool and you won't give it to me. Also, you actually asked the two princesses to mess with my queen.

To be honest, it was not Yang Heng's idea to bother Changsun. Yang Heng thought the two princesses would bother Li Er's palace. In order to make the two princesses do this, Yang Heng was a good actor.

"Two princesses, my house is newly built, so don't worry, why don't you make a fuss? Otherwise, let's try it in the yard." Yang Henghua said pitifully, "No, just build it in this house, otherwise how can we know the quality of the stove?" At first, Yang Heng planned to tear down the roof, but then he thought, no, if the two princesses don't tear down the roof, wouldn't it be in vain to act? So he changed it to a lattice on the door. You must know that the lattice of the Yang Heng family is ordinary wood. When the two princesses leave, they will be able to make up for it.

Yang Heng did not expect that Li Er was here at Changsun, and the two princesses were not distinguished from Changsun or Li Er's territory. We had to cook and cook for our father to eat. This was their idea.
