In fact, if it's just a matter of money, Gu Dong has a way to get it.

He found a lot of jewelry in Technopolie, some of which were obviously gemstones, diamond rings, etc., so if he sold them, they would definitely be worth a lot of money.

And Gu Dong was almost certain that these things were true.

But the most important problem now is that he can't reasonably own these things.

Say it was picked up?

Thinking about this matter seriously, Gu Dong felt that he still had to use other methods, for example, to use the method of manufacturing high-quality graphene to ask his father for a little money.

Dad is an electrician and knows very well what batteries do.

The manufacture of high-quality graphene is not high-end, in the final analysis, it is obtained by the method of graphite oxide, but the steps are different.

Graphite oxide requires some small equipment, which most of Gudong can make.

Although the graphene he made himself was certainly not as good as the small spider-man's one, it was enough to have this excuse.

He was just trying to find an excuse to ask for a little money.

Thinking like this, Gu Dong made up his mind.

He still had some savings in his hand, about 2,000 yuan, and he threw it out at once, bought some instruments online, and then had them delivered to his doorstep.

Tang Xiu seemed to have a little money over there, Gu Dong thought about it, and then directly borrowed a thousand yuan from her......

Speaking of borrowing money, it was quite funny, that day Gu Dong was thinking with a sad face, what should I do? As a result, Tang Xiu sent it directly to the door.

After Gu Dong told her, the little girl was immediately startled, and asked in slight surprise, "You want to borrow a thousand yuan?"

Gu Dong nodded and said, "Yes, do you have it over there?" If not, then forget it!"

Although their family is not poor, for high school students like them, a thousand yuan is actually a lot of money.

If it weren't for the New Year's money, there wouldn't be so much at all.

Tang Xiu seemed to be a little happy, staring at him with big bright eyes and asking in surprise, "Brother Dongzi, why do you want so much money?"

Gu Dong smiled: "I want so much money, it's naturally useful, I need to buy some instruments!"

"Buy instruments?" Tang Xiu continued to be surprised.

"Hmm!" Gu Dong didn't hide it from her, nodded and explained: "Aren't I studying that battery? Recently, I feel that it is almost the same, and it can be manufactured, but now it needs some instruments to cooperate." If you have money, lend it to me first, and when I make money, I will pay you back double!"

Tang Xiu asked again: "Is that the lithium battery you studied?"

"It's not a lithium battery, it's something else!" Gu Dong smiled and said, "I feel like I'm about to research it!"

"Brother Dongzi, you are really good!" Tang Xiu smiled, took his schoolbag and looked for it, then looked up at him and said, "My money is all at home, I need to go home to get it." Brother Dongzi, I still have 3,000 yuan!"

"Three thousand yuan?" Gu Dong was surprised.

Tang Xiu nodded, and said with a smug smile: "Yes, I have saved it for a long time, and it is all left from before, if Brother Dongzi wants it, I can give it all to you." ”

Gu Dong was also happy, thought about it, and said with a smile: "If there are three thousand yuan, it will be even better." Xiuxiu, don't worry, when I make money, I'll pay you back twice!"

Tang Xiu immediately laughed: "Well, then let's say it, you will pay me back nine thousand yuan in the future!"

Forehead!

Gu Dong was choked and looked at her: "Isn't double six thousand yuan, how did it become nine thousand yuan?"

Tang Xiu blinked playfully, full of cunning, and said with a smile: "Of course it's nine thousand yuan, and there is interest! Only six thousand yuan is too little." Brother Dongzi is so good to me, of course I have to have more with Brother Dongzi. ”

Gu Dong couldn't cry or laugh, in fact, Tang Xiu was just joking with him when he said this, this girl was still very generous when she was generous.

After thinking about it, he had no choice but to laugh and say, "Okay! Nine thousand is nine thousand! I didn't expect your little girl to be so treacherous, I won't borrow money from you in the future!"

"Ha, of course!" Tang Xiu blinked his eyes and laughed playfully: "I won't be polite to Brother Dongzi." Brother Dongzi, have you really researched that lithium battery?"

Gu Dong smiled: "It's all said, it's not a lithium battery, it's something else, it's almost." I feel like I can make something out. Originally, I was thinking about where to get some money, but I didn't expect our family's Xiuxiu to send it to me. Haha, Xiuxiu, you may be my lucky star. If I make a lot of money in the future, I will definitely be indispensable to you!"

When Tang Xiu heard him say this, his heart felt as if he had eaten honey, fragrant and sweet, and immediately smiled: "Thank me so much?

"Done!"

With money, it's easy to do things, three thousand plus two thousand for a total of five thousand, that's enough, at least it's enough to buy equipment for making graphene.

He doesn't need to be good at first, as long as he can make it, and with this excuse, the money will continue to come later.

The 5,000 yuan was quickly spent, and all kinds of equipment and instruments were delivered to the doorstep one after another.

Although my father was laid off, he was looking for a new job these days, and he was still away from home most of the time, so this gave Gu Dong some space to move some equipment into his room and assemble it by himself.

Graphite oxide does not require many parts, it is very simple equipment and instruments.

After the equipment and instruments were assembled, Gu Dong immediately chose a time when his parents were out to take some graphite for oxidation.

Tang Xiu was very curious about what he made, so he also came over to take a look.

Because these graphenes were originally intended to be shown to others, all Gu Dong did not hide it from her, and when she saw Gu Dong extremely skillfully manipulating several chemical instruments, she looked slightly surprised.

In one of the glasses, a yellowish liquid appeared, and on the surface of the liquid, a layer of yellowish needle-like crystals appeared.

"Isn't this a battery?" she asked, surprised.

"No!" Gu Dong smiled: "But this is something better than a battery." ”

"What's that?" Tang Xiu asked.

"It's called graphene nanoribbons!" Gu Dong smiled mysteriously, looking at the fruits of his labor with great satisfaction.

Tang Xiu didn't seem to have heard of graphene, and was slightly surprised: "Graphene nanoribbons?

Gu Dong glanced at her and said with a smile: "Something that can make a lot of money." Xiuxiu, this thing is said to be able to change the world!"

"Uh!" Tang Xiu was a little crying and laughing when he heard this, and said, "Is it? Then Brother Dongzi is happy." With so much equipment, Brother Dongzi has already spent all the money?"

"Almost!" Gu Dong smiled: "But this equipment is kept secret for the time being, and you are not allowed to tell outsiders without my permission." There's room for improvement!"

"Giggles, I'm sure I won't tell outsiders!" Tang Xiu smiled: "I thought Brother Dongzi was studying something?

Gu Dong smiled.

Although the graphene that is made today is very poor, it is indeed graphene, which is a two-dimensional crystal composed of a single layer of carbon atoms.

It's only 5,000 yuan, and most of the money is used to buy equipment, so at present, Gu Dong has not made much, only a loss.

But it did.

The process is also very simple.
