Chapter 259

In the backyard of the county men's residence, the door of Li forgetful's study was closed.

Aphrodite and Perrin could only hear the voices of their husband and sister Changqing from time to time in their study.

Especially my husband, his breathing sound is quite rapid, and he seems to be doing some vigorous exercise in the room.

"Ah! Hurry up, hurry up!" Su Changqing's excited voice came from the study.

"Hoo... I can't, rest... Let me rest for a while." Li forgetful's panting voice came.

"Forget your worries, don't stop, don't stop, continue!"

"Hoo, I'm so tired. I can't. let me rest for a while and then continue."

"You're useless. It's time to exercise."

"Well, how can you talk? How can you say that men are useless? I've insisted long enough! Half an hour?"

"Hum, it's useless. It's only ten minutes at most!"

“……”

Little girl Peilan didn't know why. She wanted to knock on the door of the study room to see what sister Changqing and Lang Jun were doing, but she was dragged away by Alfred.

Although Alfred is a virgin, he seems to hear such a voice in the Hu people's wine shop

However, there is naturally no picture made up by Aphrodite in the study, which is not suitable for children. But Li forgot to worry, panting and shaking the handle of the generator

At one end of the generator, two silver wires are wound around the beautiful boss's mobile phone charger. The data cable of the charger is connected to the mobile phone, and the charging icon is displayed on the mobile phone.

Obviously, Li forgot to worry about the success of the generator and is now charging his mobile phone.

Li forgot to worry about learning slag before and was baffled by the question raised by Su Changqing. How to insulate metal wires is a very serious topic in the Tang Dynasty.

After pondering for a long time, Li forgetful and Su Changqing don't know how to insulate the metal wire.

Where was it that easy to make a hand-operated generator 1300 years ago?

The "generator project", which has been busy for a long time, has not yet begun to end in failure, which has hit Li forgetful and depressed for several days.

However, there was no way out of heaven. Li Qieyou soon found a way to solve the problem of wire insulation - painting the wire with a layer of paint.

The use of raw lacquer was recorded long ago in China. In the book of mountains, seas and North mountains, it is said: "the wood of Guo mountain is mostly painted brown. The wood of Yingtan mountain is mostly painted wood."

Raw lacquer is a pure natural liquid coating cut from lacquer tree. Because of this, the output of raw lacquer in China since ancient times is low and expensive, which can not be used by non dignitaries.

Not to mention that it is impossible for ordinary people in the Tang Dynasty to paint their furniture with raw paint. Even in the families of powerful people in the Tang Dynasty, few can use raw paint. Because raw lacquer is non-toxic, it is often used to make tableware.

In Li's house, there is a set of wooden tableware painted with raw lacquer.

This is a congratulatory gift sent by a dignitary in Chang'an City after it was reported that he was granted Huxian baron.

Li forgot to worry about how to insulate the metal wire. When he was eating, he saw his maid serving him with this set of lacquer wood tableware. Then he suddenly had a flash of inspiration and thought of the good thing raw lacquer.

Li forgot to worry and couldn't help laughing. He couldn't take care of his meal. He immediately found Niu Wu and asked him to buy some raw paint for himself.

Where to buy raw lacquer?

Nature is still a universal medicine shop... There is nothing wrong. Raw lacquer is still a kind of medicinal material.

"Compendium of Materia Medica": "dry lacquer is used as medicine to cure the absolute injury of this divination, renew muscles and bones, fill marrow cells, secure the five internal organs, invade the five internal organs and six emergencies, pinch the spleen due to wind cold... It has the dynamic effects of expelling insects and relieving cough."

Chinese medicine is so awesome!

Everything can be used as medicine. Li Qieyou admires Chinese traditional medicine and always wants to find out how they found that these strange things can be used as medicine?

What's more, the ancient Chinese were able to keep the raw lacquer from solidifying and hardening.

The method is to throw a few crab shells into the raw lacquer, so that the raw lacquer can remain liquid without drying and hardening.

The raw lacquer cut from Shandong, Gansu, Guizhou and other places is transported all the way to Chang'an City by several crab shells. It is very magical.

After Niu Wu bought raw lacquer from the county medicine shop, Li forgot to worry about soaking all the silver and copper wires in the raw lacquer. After they were taken out and dried in the shade, they became a simple version of enamelled wire.

Finally, with insulated silver wire and copper wire, Li forget worry's "Datang generator plan" which has been put aside for several days has a chance to restart.

Carefully winding the enamelled silver wire on the stator and tightly fixing the magnet on the rotor, a simple generator to the extreme is completed.

But whether this thing can generate electricity or not, no one has a clue, whether it's Li forgetful or a beautiful boss.

If in future generations, you can connect a small bulb and see if the bulb lights up after shaking the handle, it will be clear. But Datang doesn't have a light bulb. If you want to try whether the generator can produce electricity, you have to rely on "human experiment".

Li forgot to worry. The thief smiled and asked Niu Wu to hold both ends of the silver wire.

"Lang Jun, what are you doing?" Niu Wu asked foolishly.

Li forgot to worry, holding back a smile and pretending to be relaxed, said, "nothing. I made a gadget and let you try. Niu Wu, hold these two silver wires and don't let go."

The beauty boss rolled his eyes on one side, but he didn't stop Li forgetful's funny.

Anyway, now, in addition to the direct induction of the human body, she doesn't know whether the thing li forgets to worry about can generate electricity.

Niu Wu was confused, but he didn't feel anything wrong. He pulled two silver wires tightly with his hands and watched Li forget you quickly shake the handle

"Ah!" Niu Wu uttered a scream and immediately shook away the two silver wires in his hand.

"Lang Jun, why does this silver wire bite?" Niu Wu shook his hands and looked in horror at the two silver wires connected to the hand-operated generator.

Li forgets worry and the beautiful boss, but their eyes brighten and stare at Niu Wu: "Niu Wu, do you really feel it?"

"Yes, it hurts very much. Mr. Lang, What immortal method are you playing with? Why does the silver thread suddenly bite? Has it been refined by you?" Niu Wu stared at the big eyes of Tongling, shocked and inexplicable.

Li forgot to worry but ignored him. He looked at the beautiful boss: "this should be a success?"

Su Changqing nodded uncertainly: "maybe? It seems that the current is not small, otherwise you can't make Niu Wu electricity like this."

"Then try?"

"Well, try it."

Niu Wu was confused, but no one explained to him. Li Qieyou and Su Changqing picked up the hand-operated generator, ran back to the study, and closed the door again.

So there was the scene that Perrin and Aphrodite heard outside the study.

In any case, Li Qieyou's extremely simple hand-operated generator was a success. Su Changqing's mobile phone screen, which has been powered off automatically for a long time, now has a charging icon on
