Ye Mei was so depressed that she was arranged by Yang Yuxin to have a fake show with the daughter of Anshi City, but Li Chengqian was in a good mood in Chang'an City. Seeing the rubber-like thing made by the "master" Taoist priest, she was trembling all over.

"How much more is this thing? Is it insulated?" Holding the rubber rod in his hand, Li Chengqian was excited and completely ignored the fact that this thing was not rubber at all.

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

Can a guy who doesn’t even know electricity still expect him to know insulation? Of course, the Tang people still know the lightning, but if you talk about electricity alone, I’m sorry, I don’t have this concept!

"Insulation is..., forget it, you can make more of these things and make them into thin sheets. If they are of this size, they should be so big." Li Chengqian used his hands to roughly compete in a hugging posture, and then drove the "master" out.

"Who, go find Lao Liu and ask him to get an iron plate for this palace. It probably needs to be so big." Looking at the back of the 'master' leaving, Li Chengqian once again made a hug gesture to a guard standing at the door, and sent the person out at the same time, but soon he called the person back: "Wait, let Lao Liu get an iron rod as thick as a finger, which is ten feet long, go."

The series of tosses confused countless people, only Li You was eating without anyone else, and looked down on Li Chengqian's busyness.

"Your Highness, what can a ten-foot-long iron bar be used for?" Shu Tian, ​​as a personal adjutant, needed to always grasp the movements of the 'leader'. While Li Chengqian was still excited, he couldn't help but ask.

"Of course it is for conductivity. By the way, don't be idle. Find some people in a while and go to Xichiyuan to dig a trenches for me, so that I can dig deeper." Something similar to rubber made Li Chengqian feel excited until he was on the verge of diaper, and the arrangements of all things are inexplicable.

But there is no way. The emperor is not at home, except for the queen, the prince is the biggest. As long as he doesn't kill anyone, making a slab and digging a trench is really not a big deal.

Of course, Shu Tian didn't need to feel uncomfortable for this little thing. He didn't need to dig a trenches anyway, so he ran to find someone without any complaints.

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

"Do you know how to thunder? The one that flashed before was electricity." Li Chengqian sat next to Li You, wiped the sweat from the top of his head because he was too excited, and picked up the chopped cold melon and ate it. Only after 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, watch TV, and you can..." As he said that, Li Chengqian stopped and seemed to be stupid.

Damn it, I don’t know if I don’t say it, I was shocked when I said it! Li Chengqian suddenly realized that even if there was electricity, it was useless because he had nothing to use electricity.

Just now, I just thought that if I had rubber, I could make wires, and then I tinker with the generator, and then... I found that the ideal was full and the reality was skinny! He had to face the difficulty of not having electrical appliances.

"Brother, brother, what's wrong with you?" Li Chengqian was so muddy that Li You were scared. This guy who was still two years away from becoming an adult three times, came to his side in two seconds and raised his slap.

"If you dare to fight, do you believe it or not, I will deduct your pocket money?" Li Chengqian, who was stunned, used his light to discover Li You's actions and couldn't help but snort.

"Ah, hehe..." Li You smiled awkwardly and withdrew his slap with regret: "Brother, what were you thinking just now? Also, what is a TV? What is a phone? What is a cell phone?"

"Mobile phone? Did I just talk about mobile phone?" Li Chengqian looked at Li You with no spirits and asked mutely.

"Yes, I said it." Li You nodded seriously.

Speaking of such high-end things as mobile phones, no one in the Tang Dynasty can say except Li Chengqian. Li You can know it, which is enough to prove who said it.

"Just pretend you haven't heard of it. Everything is just a mirror and water moon." Li Chengqian, who was stimulated by reality, had no interest in explaining to Li You what a mobile phone was. After perfunctory, he began to daze again until Liu Min, who was the general, ran to him to find him.

"Your Highness, can you tell me what you are going to do with a ten-meter-long iron bar? Can't you be more delicate?" This is the first sentence when Liu Min saw Li Chengqian.

"How thin is it? Can you still make wire?" Li Chengqian said angrily.

"If it is silk, the iron ones are not good. This one must be made of gold, just like those used on His Highness's clothes."

Golden wire? Who uses golden wire for electric wire? Isn’t this too rich? Li Chengqian complained fiercely in his heart, and then looked at Liu Min and said weakly: “You try your best. As long as you can make it ten feet long, you can use iron if you can use iron. If you can’t use iron, use copper if you can’t.”

The Central Plains lacked copper, not only in later generations, but also in the ancient Tang Dynasty. Moreover, due to low productivity, the Tang Dynasty lacked copper and was not ordinary.

"Here!" After clarifying what he should do, Liu Min felt relieved and agreed to get up and leave, leaving Li Chengqian to continue sitting there in a daze.

Li You circled around him for a few times, but he felt bored, so he patted his butt and left. There was still a slack outside, and it seemed that it was much more interesting to go to him to play with him than to get along with Li Chengqian.

In this way, two days passed in a flash. On the third day, the sky above Chang'an City was covered by the dark clouds that Li Chengqian had been waiting for for a long time. Looking at the drooping clouds, it always gave people the feeling that the sky was about to collapse.

In the main hall of Lizheng Hall, an iron spear with a cold light stood on the top of the hall. Under the iron spear was a long copper wire, until it was connected to an iron plate on the ground.

On the iron plate was a sheep with four hooves tied together. The poor guy was screaming in horror while surrounding Li Chengqian and more than ten people.

But it was obvious that no one cared about this poor sheep at the moment. More than ten people looked up at the sky, with their eyes full of anticipation, as if some gods and other figures appeared in the sky.

This is an experiment, an experiment about lightning, but because there are no electrical appliances, the success of this experiment has become less important. If Li Chengqian had not wanted to try whether the rubber was insulated by the "experts" to try whether it was insulated.
