Even if Wang Fuzi's senior brother who is proficient in astronomy and geography and has excellent medical skills, he has asked for advice, but he does not understand what electricity is. It's just that Yang Ruo, a fourteen or fifteen-year-old girl, how could she know?

"Shall I try my best?" Yang Ruo knows the principle of power generation, but it is more troublesome to make an electric motor, but she has those things in her mind.

The strange thing is that since Yang Ruo was reborn, his memory has indeed become better and better. A lot of things, such as some recipes, she remembers, it can be called a living version of Xiaobaidu.

But whether it can be done in the end depends on how many materials they can provide her.

At this time, Yun Yan couldn't help but persuade on the side, "Master Wang, I advise you to think twice, what if there is still danger in this, if it weren't for Yang Ruo today, you would be in danger." ”

"Girl, if you teach me how to generate electricity, I will allow you to make a request to me." Today, he owes Yang Ruo a great favor. Thinking that Yang wanted to teach him how to generate electricity, he immediately marked his attitude first.

When Yang Ruo heard this, his eyes suddenly lit up. "What the Master said is true, including any requirements?"

When Wang Fuzi saw Yang Ruo's eyes that emitted a strange light, how could he feel like he was in a trap. But if you say it, it is the water that is spilled, and you can't get it back. And for the sake of face, he also has to be generous. He hurriedly replied: "Of course, as long as I can do it, I will definitely promise you." ”

"That's great." Yang Ruo's heart was suddenly full of joy, in this way, wouldn't she have to go all out.

Fortunately, when she was in school, she did well in physics and chemistry, and it was more than enough to get a few to deal with them at her fingertips.

Wang Fuzi stretched out his hand and showed Yang Ruo the big gloves that were thrown on the table. "Girl, what I don't understand is why you can pull me out with those big gloves when I'm electrocuted. Also, you said that Yunzine was going to save me in front of you, and the posture was not right. ”

Yang Ruo picked up the life-saving gloves and looked left and right. Cai said: "I'm ashamed, last time I said that I wanted to make gloves for my master and Aunt Yun, but I saw the workmanship of this glove today, and I was really ashamed." I'm not so good at my craft. ”

Master Wang hurriedly said: "This is what Aunt Yun did." If she does it, you don't have to do it. ”

That day, Yang Ruo talked about making gloves, and Yun Zine made a few pairs of gloves according to her request.

I kept two pairs for myself and gave two pairs to Master Wang, but I didn't want to, it was this pair of gloves that came in handy today and saved my master's life.

"This brings us to insulators and conductors. We also have damp wood, graphite, and saline solutions in our human body, which are easy to conduct electricity. Dry wood, cloth towels, paper, fur, etc. are insulators. If Aunt Yun pulls you directly with her hands, because the human body is also a conductor. Not only will it not save you, but it will also be electrocuted at the same time. It could lead to both of us being electrocuted at the same time. But I had gloves on my hand and it cut off the power so I could save you. ”

"Oh, I see." Wang Fuzi had a look of sudden realization on his face.

"In fact, this is also a phenomenon of physical science, but electricity is a very magical thing, and ordinary people don't know it." Isn't it, the generation of electricity was discovered as early as 585 century BC. However, from discovery to popularization, this process took hundreds of years.

We have realized the era of upstairs and downstairs electric lights and telephones, and it is not more than a hundred years. No wonder they don't know anything at this time.

Master Wang was silent for a while and did not speak, and Yun Yan also had a look of surprise on his face. They had to digest what Yang Ruo said well in order to fully understand.

Now I can only memorize what she said by rote.

At this time, Yang Ruo took out an empty bowl, sniffed the seasoning in front of him again, and scooped some into the bowl.

After she had mixed the bowl of thick salt and sugar solution, she brought it to her master.

"Master, your electrocution today is relatively short, and it is relatively light, so there is no major problem. After you drink this bowl of water, pay attention to rest, this can help you replenish your energy and the water lost in your body. ”

Wang Fuzi saw that Yang Ruo spoke in a set way, and he no longer regarded her as a teenager and a half-year-old child. Smelling it, he picked up the bowl and drank it all in one gulp.

"It's salty, sweet and salty, it tastes weird."

Yang Ruo smiled, "This is a salt sugar aqueous solution, which can replenish the electrolytes in your body." ”

"What is the term electrolyte, and what do you mean by physics?"

"Yes, it's a physical term. You'll understand later. ”

Master Wang nodded, put the bowl down, and wiped his mouth with his wide sleeves with some grease.

He must be usually unkempt, Yang Ruo really can't imagine how a person like him can be the emperor's imperial chef.

She even had some bad taste to think of the scene when Master Wang wiped his mouth with an oiled sleeve while cooking imperial meals. When the emperor sees such a royal meal, can he still eat it?

After Wang Fuzhi finished smashing his mouth, he looked at Yang Ruo again and asked, "Girl, how do you know this?" It's hard to imagine that you have so many things in your little brain besides cooking. ”

Yang Ruo couldn't help but smile modestly. "I have met a master of the Tao before, he is familiar with astronomy and geography, Qimen Dunjia, but unfortunately I only cooked for him for a few days, and learned a little bit from him.

He ate my food for three days and then left. He taught him the principle of power generation, but unfortunately I learned too little. After Yang Ruo finished speaking, he still looked regretful.

She is actually talking nonsense casually, and no one has checked it anyway, so it's better to say it is more mysterious.

"He didn't say, where is he?" Master Wang was full of surprise on his face, he was actually taught by a master, and sure enough, he was taught.

Yang Ruo shook his head, and said with a little regret on his face: "He said that if we are fated, we will definitely meet again." He usually travels all over the world, but where he is at the moment is really unknown. ”

"It's a shame." Mr. Wang's words seemed very regretful.

At this time, Yun Zine found paper and pen from elsewhere. "Ah Ruo, what do you want with paper and pen."

Yang Ruo said thank you, drew and wrote on the paper, and made it for a long time. Finally, he wrote down the materials he needed and the things he wanted the king to do.

"Show me it." Wang Fuzi took what Yang Ruo had written.

"What is this big pool for?" Seeing that Yang Ruo drew a big pool on paper, and the pool was full of some discarded things that are usually useless, he couldn't help but be a little curious.

Knowing that Wang Fuzi was a problematic old man, he couldn't help but patiently explain: "The one I made is called a biogas digester, don't look at it is full of biogas, but we can use waste gas, not only can we use it to generate electricity, but also can be used to increase indoor temperature, can be used for cooking, fruit storage, and can also be used in agricultural production." ”
