The peddler looked at the place where Li Er pointed, "Oh, the steel pipe is built on a shelf, so that the workers can climb up, as for the gray surface, we call it cement, I use it to solidify and bond the bricks, just like the glutinous rice milk you use, but this is made of stone, after calcination, it solidifies when exposed to water, and is invulnerable!" ”

Li Er's surprised cigarette forgot to smoke, and it took a long time to "Zhijie, Zhijie, you come here!" ”

"Hey, it's coming, what's the prince doing?"

"Zhijie, go and take your iron lance and poke a hole in Dabao's wall, I don't believe that Dabao's cement is so strong!"

Lao Cheng saw that the hawker did not object, phew, spit out the cigarette, spit and foamed in his hand, and took his weapon from the hand of the family next to him, a stainless steel lance, the hawker only then knew that this product was not made of a plate axe, it seems that the novel also has a misleading time, Lao Cheng held the lance upside down, and poked it against the wall with the point steel tip on the handle of the lance, and with a bang, a spark, leaving a white mark on the wall, Lao Cheng hurriedly threw his lance, his hands trembled, it is estimated that it is bald skin, we all know that the lance is similar to a mace, It's a big thorny head, estimated to be no less than twenty pounds, plus twenty pounds of rods, Lao Cheng's fierce effort, because he didn't prepare in advance, he suffered a dark loss!

However, this also indirectly confirms that the cement thing is indeed better than ordinary building materials, Li Er couldn't believe it, and touched the seal smashed out by Cheng Biting the gold, "Tsk, amazing, I didn't expect there to be such a wonderful thing in the world, if I didn't see it with my own eyes, I can't believe it!" ”

"Forget it, Brother Li, don't think about it, I have a lot of novelty gadgets, let's take a look at the horseshoe I brought you, that thing is a sharp weapon to save your thousands of military horses!"

As soon as the hawker mentioned the horseshoe, Li Er immediately forgot about the cement, after all, he couldn't do this thing for a while, and the horseshoe was related to the military affairs, "Go, where is it!" ”

"Here, it's this gadget, it's very simple, oh, don't think about those two, that's more handicrafts than practical, this simple iron palm is the most practical thing!"

Li Er put down the aluminum alloy horseshoe, picked up an iron palm and played, "Such a simple thing, no one in my Datang has come up with it, it's really....right Dabao, how to use this thing!" But I finally understood why I wanted to give money in the first place, and the vendor refused to do it!

"It's simple, hey, which of you would want to contribute a horse?" The peddler looked at the people present.

Qin Qiong took over the conversation: "Use my yellow horse!" ”

"Hey, Brother Qin, didn't your yellow horse sell? How can there be? ”

Qin Qiongle's smoke came out of his eyes, "Oh, Dabao, do you know a lot?" You know that I have sold yellow horses! ”

The peddler patted his chest and gave himself a thumbs up, "That's, don't you look at me, I mean, people give nicknames, Niu Banxian!" "This thing is a joke, and someone actually takes it seriously!

"Hehe, then why don't you know that the horse I rode later was always a yellow gelding because I missed the one I sold!"

The peddler's face immediately collapsed, and he was embarrassed, "Uh, forget it, come a few people, stop the horse, Lao Cheng, you are pulling the horse's hooves, don't let it kick me, who else has a dagger, the better!" ”

After getting Li Er's hint, a guard on the side handed over a short dagger, and the peddler despised it, stingy, and was afraid that he would stab himself! Exactly, the shorter the better, Lao Cheng pulled the horse's hooves, the hawker took the knife and scraped off the old cuticle on the horse's hooves, took the horseshoe and made a comparison, took out a nail from the package, and directly knocked the dagger handle into it, and saw that the guard frowned in distress, it is estimated that this thing is his beloved thing, and now he is used as a hammer by this goods, and he can't stand it.

The peddler doesn't care if he is distressed or not, anyway, it's not his own thing, fortunately, this yellow husd is more honest under Qin Qiong's appeasement and Lao Cheng's restraint, and he nailed the four horseshoes very smoothly, and the tired hawker sweated, "Okay, that's it, Second Brother Qin, you ride it up and try it to see how it feels!" ”

When Qin Qiong heard this, he pulled his yellow horse and turned over, and the people around him looked strange and made way for Qin Qiong to go out, Qin Qiong rode a horse and ran two back and forth along the stone road in the street, and after bolting the horse, he pulled up the horse's hooves and looked at it, "Well, good thing, I have picked up the bad road in these two laps, you see that the edge of the horse's hooves does not have any traces of bruises and cracks, and this thing is simple and easy to make, it is indeed as Dabao said that it is suitable for my thousands of military horses in the Tang Dynasty, the prince is a good thing!" ”

This sounds awkward, and sure enough, Li Er's face also darkened, but thinking of Qin Qiong, it was probably a slip of the tongue, "Well, this horseshoe is indeed a good thing, thank you Dabao!" ”

"The prince is polite, thank you, by the way, I have tea for Your Majesty, help bring it when the prince leaves, I won't enter the palace!"

"That's fine, but I'll score a point!" Li Er followed the vendor to the side of the car, opened the car door to take out the tea inside, and hugged two sets of tea sets, the glass tea set shone in the scorching sun through the transparent packaging, and the eyes of the people who followed Li Er lit up, to be honest, since this goods came, these people have seen more novelties than they have seen in the first half of their lives.

Everyone wants to pull good things home, the eldest grandson Wuji really can't help it, literati, of course, they are more concerned about things that can improve Yaxing, just like Lao Cheng and their group of generals care about bicycles, "Niu Daochang, how much is this tea set worth?" ”

Go on the road! Give thirty-two likes, let's bring this thing to give gifts, then it must be sold "two taels of gold, thirty taels of silver, and forty taels of money!" "I don't know the rules of the hawker listened to this price and gasped, of course I also took a breath, today the sun hit the west out, Niu Daochang sold things cheaply, usually this thing is not less than five taels of gold, even those girls at home wipe their faces to five taels of gold, today this set of tea set a pot of four cups is only two taels, cheap!

"I want, I want, and I have me!"

"Don't quarrel, don't argue, the prince is still there, if you want to go over there to register, pay the deposit first, and today while the prince is here, everyone who pays in gold will send two taels of tea! Well, if you need it, go and register! ”

Li Er, who already has a certain immunity to this money fan, didn't say anything, and instructed his subordinates to take away the share sent by the hawker and didn't care about it, anyway, he didn't ask him for money, this is Li Yuan who exchanged ginseng for "By the way, Dabao, you should tell me about this mixer and that vibrator!" ”

"I can't see it, the prince is very concerned about building a house!"

"Isn't this Your Majesty's stay in your examination school, so care about it!"

"Well, that's right, give it, Brother Li drinks Coke, Lao Cheng, you take it yourself, but don't move home, I will cut off his goods after anyone moves!" Regardless of Lao Cheng, the mess when they got in the car to grab Coke, anyway, every time the hawker sends something for free, there is no time not to grab it, "Brother Li, this mixer and vibrator are nothing, and it is the same for adult stirring, the main thing is to help people save some effort, and the biggest or so in this is this generator!" “

The vendor took Li Er to the side of the generator, kicked the generator with his foot and said to Li Er, "This thing drinks oil, then converts it into electricity, and then goes to the motor over there through the wire, and the motor does the work to drive the mixer and vibrator!" “

Li Er squatted down and was about to touch the generator with his hand, but the hawker hurriedly stopped, "Don't touch it, if there is a leak, it will be troublesome!" “

"What happens if there is a leak?" Li Er asked suspiciously.

"Brother Li, have you ever seen someone killed by thunder?" After asking the peddler, he regretted it, and in the novel it was said that Li Er had a younger brother Li Yuanba who was killed by thunder, hoping that this was wrong.
