Tang Shanzhi was really killed by Li Chengqian this time, and after recovering, he didn't say a word to Li Chengqian for five days.

But fortunately, Li Chengqian couldn't use him now, so he simply didn't care about him, and ordered someone to make this generator again.

The so-called one has two, there is positive and negative, that is, I don't know what the current and voltage are, so it is better to make another one according to the original appearance, and then connect it with copper wire.

In this way, the newly made generator becomes an electric motor, that is to say, through the conduction of wires, and then the generator works in reverse to complete the conversion of electricity to magnetism and then to kinetic energy.

So when Li Chengqian saw that the stator of the other motor began to rotate, an excited smile appeared on his face again.

……

"Li Gaoming, what was the purpose of asking me to pick up that thread last time?" Looking at the excited smile on Li Chengqian's face, Tang Shanzhi finally couldn't help it anymore and ran to him and asked.

"Haven't you reacted yet?" Li Chengqian looked at Xiao Tang and smiled happily.

"You let me go on purpose, didn't you? I just want to see if that thing is good, right? Xiao Tang said depressedly.

"No, I just think it's a bit of a hindrance to put that thread there." Li Chengqian shook his head, and when he saw that Xiao Tang was still staring at him, he sighed and said, "Good knowledge, you said that you are a big man, why are you so stingy, can't you be generous?" ”

"Me, I'm stingy? I ......" Tang Shanzhi was almost fainted by Li Chengqian,

Girl, don't say anything about Lao Tzu half dead, and now you still say that Lao Tzu is stingy? Is there really no place for this Datang to be reasonable?

However, Li Chengqian didn't give him a chance to continue talking, patted him on the shoulder and said, "From today onwards, we will get rich, you know?" ”

"I don't know." Tang Shanzhi, who felt that he had been deceived by Li Chengqian again, said angrily.

"I don't know? It's stupid. Li Chengqian smiled disappreciatively, and then said to Xiao Tang: "You will go to the ironworks again in a while, and get a set of small propellers back, remember not to be too big."

"Got it." Tang Shanzhi agreed, and flew away, as if he didn't want to stay by Li Chengqian's side for a moment.

……

When the propeller blades were brought back, Li Chengqian knew that this time the matter was estimated to be tossed again.

Because the two motors are exactly the same, the speed of the other reversed motor is also the same as the speed of the transmission shaft of the steam engine, which is equivalent to saying ...... There was no such thing as an electric fan, and he had to change another motor to increase its speed.

So another round of tossing began.

……

This time, Li Chengqian tossed for nearly two months, and when he came out of the Datang Academy of Sciences, not only Su Mei and others, but even Empress Changsun was a little afraid to recognize his son.

With his oily body, his long beard, and his messy hair hanging down one by one, even the beggars on Suzaku Street were much cleaner than him.

"Qian'er, what are you busy with all this time? Why is it so sloppy? Empress Eldest Sun looked at her son and frowned dissatisfied.

From the mouths of Su Mei and others, Empress Changsun knew that her son seemed to have been busy for half a year, and sometimes he didn't even return to the palace, and he stayed outside for ten days and half a month.

"Queen Mother, Erchen has made a gadget out during this time, and I will install it for you in a while, so that you won't have to suffer from heat and dryness in the summer." Li Chengqian didn't realize the suppressed anger of the old lady, beckoned excitedly, and ordered someone to lift the electric fan that had been successfully made.

"What is this?" Empress Eldest Sun looked at the huge object with the propeller blades in confusion, completely unable to understand what it was.

"The queen mother is a little restless, and the son of the son will be sold first." Li Chengqian smiled mysteriously, ordered someone to place a huge electric fan in a corner of Empress Changsun's room, and then led people to the courtyard.

……

The slender wires pierced through the ridge of the house, bypassing the sky above countless palaces, and hundreds of palace people were turned around by Li Chengqian's instructions, and the eldest grandson queen frowned vigorously.

His Majesty Li Er, who was reviewing the folds, was also alarmed.

Since the last time Li Chengqian took advantage of the bombing of the East Palace and began to pretend to be sick, the old man took back power and started a life of countless folds again.

The husband and wife watched Li Chengqian tossing there like a foreman, and wanted to call him several times, but in the end no one spoke.

There is an old folk saying that dogs can't change eating, Li Chengqian can't change this kind of habit of tossing, rather than telling him to stop, it's better to see what tricks he can toss.

……

Soon, when the time came to night, His Majesty Li Er, who had returned to the study to complete the recital, looked at the sky outside, and then looked at the courtyard that had quieted down, and slowly paced to the sleeping palace of Empress Changsun.

As soon as he entered the door, the old man immediately felt something different, there was a breeze in the originally stuffy room, and when he looked closely, he found that there was a large thing in the corner of the room that was constantly rotating, and the wind was blowing from there.

"Your Majesty is done with official business?" Empress Changsun was sitting on the sofa reading a book on the side, and when she saw Li Er coming in, she put the book aside and greeted her.

"Is this what the rebel has been busy all afternoon?" Li Er nodded at his wife and pointed to the fast electric fan.

"Yes, Qian'er said that this is called an electric fan, which can replace the palace people to play the fan, or you can work twelve hours a day, if you want to be cooler, you can put two basins of ice in front of it." Empress Eldest Sun had a hint of pride in her voice.

After all, this thing is her son's filial piety, and there is no second station in the entire Datang except for her.

"Well, yes, that's good." His Majesty Li Er circled around the electric fan, and finally looked at Empress Eldest Sun and said, "But how does it turn?" And no one came to shake it. ”

"The concubine doesn't know either, but Qian'er always gets something out that people can't understand, and this is not the first time."

"Well, this rebel also knows filial piety, and you didn't hurt him in vain." Li Er, who didn't understand the working principle of the electric fan, simply didn't want to think about it, and sat on the edge of the bed accompanied by the eldest grandson, and said jealously.

"Your Majesty, where are you talking about this, isn't Qian'er afraid of disturbing your official business, so I installed this electric fan here." Empress Changsun explained for Li Chengqian.

But is that really the case? I'm afraid it may not be!

Since there is such a thing as an electric fan, in the next few days, His Majesty Li Er's office has become the dormitory of Empress Changsun, and after two basins of ice cubes are placed in front of the electric fan, the kind of comfort similar to spring makes Li Er really not want to leave here.
