I saw a huge wooden barrel with a pot of yellow-colored paste-like things.

"What's, what is this?" Yang Ruo saw a wooden stick for stirring in the barrel, she took the stick and stirred it twice.

Smelling the smell, it's a bit like rosin.

"It's rosin resin. I heard you say that these copper wires are easy to conduct electricity, and you need to find something to wrap them, so I finally found this after many experiments. When Shen Mu spoke, there was also a look of pride on his face, presumably after many efforts.

Yang Ruo didn't see that Shen Mu would actually study this by himself. However, she did know that Castle Peak Academy also taught physics courses.

Could it be that he also dabbled in these things?

Thinking of the last time Shen Mu would set up a formation, he would see him, and he even studied chemistry. Yang Ruoxin said, Shen Mu was unfortunately born thousands of years early, if he was reincarnated in modern times, he must be an all-rounder.

Yang Ruo knows that rosin is a natural resin, but to make it into a plastic component, it must be with the help of synthetic resin, does he have a formula for plasticizers.

Then I saw Shen Mu show Yang Ruo the copper wire made on the side.

I saw a piece of copper wire wrapped on the outside, light gray plastic-like packaging.

Yang Ruo's eyes suddenly lit up.

Well done, Shen Mu is really smart, he actually studied it.

Seeing Yang Ruo's expression, Shen Mu hurriedly asked, "Ah Ruo, do you think this is useful?" ”

Yang Ruo took the copper wire in his hand. asked: "Shen Gongzi, how many more have you done like this here?" We'll do a test later, and if it works, we'll have electric lights here. ”

Shen Mu saw Yang Ruo say this, and hurriedly said, "You come here with me." ”

I saw a room next door, a little messy, with all kinds of things on the floor, including rosin resin.

Yang Ruo thought to himself, this is probably the place where Shen Mu did experiments, and he didn't know how long he had been doing experiments here alone.

Thinking of this, the slightest suspicion she had about him before disappeared.

Shen Mu strode inside, pushing the things on the ground to the side with his feet, so as to push a way for Yang Ruo to stand still. "Sorry, it's a bit messy here."

Yang Ruo smiled and said politely, "It's okay." It's like this when you do experiments, and if it's neatly organized, there's no taste of experiments. ”

Yang Ruo looked around, this room was really messy. Moreover, Shen Mu would wear clean clothes, standing in this messy room, and immediately gave people a feeling that the painting style was wrong.

"Looks like you've been putting in a lot of work lately." Yang Ruo rummaged around, and there were still branches on the ground that had been cut back and were still on the side, and it was estimated that he was used for experiments.

"Anyway, I don't have anything to do, if I can really research the so-called wires, then all the schools in our academy can use electricity, and then other places can also be electrified, which will also be a great kindness."

Yang Ruo nodded, this is easy to say, but it is really not easy to do it.

Not only does it require a lot of manpower and material resources, but financial resources are the most important.

However, Yang Ruo knew the strength of Qingshan Academy, and he had the financial resources at all.

So she was right to entrust this matter to Shen Mu at the beginning.

A little inside the room, a small room, Yang Ruo saw the generator made by Shen Mu.

It's much more refined than what she did last time, and the baffles are fixed with wooden strips. The carbon rod is also a thicker one, so that the power emitted will be more sufficient.

Electric lamps are also glass bottles made of ceramics, which are used to make electric lamps, but they can also be used. It's just that the brightness is much worse.

"Shall we do an experiment?"

"Well, you can do it."

According to the steps taught to him by Yang Ruo, Shen Mu first skillfully wound the wire to the poles of the carbon rod, and then put the carbon rod into a high concentration of nitrite water.

After everything was done, I saw that the electric light was on, but the outer skin of the copper wire was also burned.

Shen Mu stared at it, and his face showed a look of helplessness.

"I've tried it many times, and the end result is like this."

Yang Ruo looked at the wires, the outside was burned black, she thought about it, and went back to look at the resin in the barrel.

Eventually, she found the reason.

"It's okay Shen Gongzi, don't be discouraged. At the very least, you've taken an important step. The copper wire was found for us, and next, as long as we could find something with insulation, wrap the copper wire thoroughly, and we were ready to put it into use. ”

"But whatever, it's true that they don't melt."

Yang Ruo thought for a moment, and then said: "I know that there is a kind of tree that can be extracted from that tree, an ingredient called plasticizer. This ingredient accelerates the consistency of the resin, which then eventually solidifies into the wires we need. ”

Shen Mu's eyes lit up, and he excitedly put his hand on Yang Ruo's shoulder. "Aruo, can you really find that kind of tree? Is there really such a magical thing in the world? ”

"Of course, in fact, the world is much bigger than you think. Like Wang Fuzi's electric oven, it's not an ordinary thing. And the electric light I mentioned, in fact, people have used it before, so what I said about this, as long as we find that kind of tree and make a plastic outer packaging that is used to cut off the power supply, our wish can be realized. ”

A contemplative look appeared on Shen Mu's face, because Yang Ruo's statement was very novel, he seemed a little excited for a while, and couldn't help grabbing Yang Ruo's arm and said, "Ah Ruo, are you saying that there are other human beings outside of our world?" Do they live like us? ”

Yang Ruo nodded, but she didn't dare to reveal too much, otherwise she would have to show her bottom. So she said in a somewhat ambiguous tone: "I once read it in a book, and that's what it said. There are some human civilizations that are higher than ours, but I don't know how. ”

"I see, I'm going to make the plastic outer packaging you mentioned. But do you know what that tree is called? How does it look? ”

This will be a calm look, and suddenly become eager.

Yang Ruo knew that Shen Mu was very fanatical about these things, just like she loved cooking. If she thinks of a new dish and doesn't try to make it herself, and then masters how to cook it, she will be very uncomfortable, and sometimes she will not be able to sleep.

The current Shen Mu is probably in this mood!

"The tree I'm talking about is called the palm tree, and the palm oil and rosin extracted from this tree are fused together, and a chemical reaction takes place, and then we can make the synthetic resin that we need."

"Then you can draw it for me, what kind of tree it is?"
