The depression in the heart of Ye Mei, who was arranged by Yang Yuxin to go to the city lord's daughter of He'an City, was indescribable, but Li Chengqian, who was in Chang'an City, was in a good mood, and looked at the rubber-like thing made by the 'master' Fang Shi and trembled with excitement.

"How many more of this stuff are there? Insulation not? Holding the rubber rod in his hand, Li Chengqian spoke incoherently excitedly, completely ignoring the fact that this thing was not rubber at all.

"Your Highness, absolutely, what is insulation?" The 'master' looked confused.

A guy who doesn't even know electricity, can he still be expected to know insulation? Of course, the Tang people still know about thunder and lightning, but if you talk about electricity alone, I'm sorry, I don't have this concept!

"Insulation is ......, forget it, you go get more of this thing, you have to make it into thin sheets, the size is so big." Li Chengqian made a gesture of hugging with his two hands, and then drove the 'master' out.

"Who, you go to Lao Liu and ask him to get an iron plate for the palace, it probably needs to be so big." Looking at the back of the 'master' leaving, Li Chengqian made another gesture of hugging to a guard standing at the door, and at the same time sent the person out, but soon he called the person back: "Wait, by the way, let Lao Liu get an iron rod thick with fingers, it will be ten zhang long, let's go." ”

A series of tosses confused countless people, only Li You, the guy, was eating as if no one was around, disdainful of Li Chengqian's busyness.

"Your Highness, what can you do with a ten-zhang long iron bar?" As a personal adjutant, Shu Tian needs to keep abreast of the movements of the 'leader', and while Li Chengqian is still excited, he can't help but ask out loud.

"Conductive, of course. By the way, don't be idle, find some people in a while, go to Xichi Courtyard to dig a ditch for Lao Tzu, dig deeper. Something similar to rubber makes Li Chengqian's whole person have been in the stage of excitement to the verge of diabetes insipidus, and the arrangement of everything is inexplicable.

But there is no way, the emperor is not at home, except that the queen is the eldest prince, as long as he doesn't kill people, it's really not a big deal to get an iron plate and dig a ditch or something like that.

Shu Tian naturally didn't need to make himself uncomfortable for this bit of, anyway, he didn't need to dig a ditch, so he didn't have any complaints to run to find someone.

"Brother, what is that 'electricity' you are talking about?" After Li Chengqian finished arranging everyone's work, Li You finally put down the cold melon in his hand, turned his head and asked.

"Thunder, you know? The one that flashed before was electricity. Li Chengqian sat down beside Li You, wiped the sweat on the top of his head because he was too excited, and picked up the cut cold melon and took a big bite before satisfying Li You's curiosity.

"Oh, but what's the use of that?" Li You continued to ask.

"That's very useful, you can light the lights, you can watch TV, you can ......" Li Chengqian paused as he spoke, and the whole person seemed to be stupid.

Damn, don't say you don't know, I'm scared when I say it! Li Chengqian suddenly found that even if he had electricity, it was useless, because he had nothing to use electricity.

I just thought that if I had rubber, I could make wires, and then I would tinker with a generator, and then ...... I found that the ideal is very plump, and the reality is very skinny! He had to face the difficulty of not having electrical appliances.

"Brother, brother, what's wrong with you?" Mu Ran's Li Chengqian frightened Li You, and this guy, who was still two years away from becoming an adult, came to his side three or two times and raised his slap.

"If you dare to fight down this time, believe it or not, I will deduct your pocket money?" Li Chengqian, who was stunned, noticed Li You's movements with his afterglow, and couldn't help but snort.

"Ah, hehe......" Li You smiled awkwardly, and regretfully withdrew his slap: "Brother, what did you just think?" Also, what is TV? What is a telephone? What is a mobile phone? ”

"A cell phone? Did I just say mobile phone? Li Chengqian's eyes were blank again, looking at Li You boringly, and Mu Ran asked.

"yes, yes." Li You nodded seriously.

Speaking of such a high-end thing as a mobile phone, no one in the entire Datang except Li Chengqian seems to be able to say it at all, and Li You can know, which is enough to prove who said it.

"You don't think you've heard of it, it's just a flash in the pan." Li Chengqian, who was stimulated by reality, had no interest in explaining to Li You what a mobile phone was, and after perfunctory him, he began to be in a daze again, until Liu Min, who was about to be a general, came to him.

"Your Royal Highness the Crown Prince, can you tell me what you are going to do with a ten-zhang long iron bar? Can't it be more detailed? This was Liu Min's first sentence when he saw Li Chengqian.

"How fine is finer? Can you still make wire? Li Chengqian said angrily.

"If it's silk, it's not iron. This must be of gold, like the one used on His Highness's clothes. ”

Gold wire? Who uses gold wire for wires? That's too rich, isn't it? Li Chengqian complained fiercely in his heart, and then looked at Liu Min and said weakly: "You do your best, as long as you can make ten zhang long, you can use iron if the material can be used, and copper will be used if the iron is not good." ”

The lack of copper in the Central Plains is not only in later generations, but also in the ancient Tang Dynasty, and because of low productivity, the lack of copper in the Tang Dynasty is not ordinary.

"Whoa!" After clarifying what he should do, Liu Min put down his heart and agreed to get up and leave, leaving Li Chengqian to continue to sit there in a daze.

Li You circled around him a few times, but he also felt bored, so he simply patted his ass and left, there was a loose pine outside, and it seemed far more interesting to go to him to 'play' than to mess with Li Chengqian.

In this way, the two days passed in a flash, and on the third day, the sky over Chang'an City was covered by the dark clouds that Li Chengqian had been waiting for.

In the main hall of the main hall of the Lizheng Hall, an iron lance shining with cold light towered on the top of the main hall, and a long copper wire was attached to the bottom of the iron lance, until it was connected to an iron plate on the ground.

On top of the iron plate was a sheep with four hooves tied together, and this poor guy was screaming in horror surrounded by Li Chengqian and more than ten other people.

However, it was obvious that no one cared about this poor sheep at the moment, and more than a dozen people all looked up at the sky at this time, their eyes full of expectation, as if there would be some gods or other characters in the sky.

This is an experiment, an experiment on lightning, but because there is no electrical appliance that uses electricity, the success of this experiment has become less important, and if it were not for Li Chengqian's desire to test whether the rubber developed by the 'master' is insulated, this experiment would not exist at all.
