Quick wear is not a cannon fodder

Although Li Nian is two years older than the original person, he is now fourteen or fifteen years old - many people in this era study late, so it is normal to be fourteen or fifteen years old in the first year of junior high school - but no matter how two years older, he is still She was still a young man, not as precocious as ancient girls, so naturally she couldn't bear hearing people praising An Ran and belittling her. She cried a few times and then hated the third wife, especially An Ran, to the core of her bones.

Li Nian may have forgotten how she boasted about herself before, and then belittled her.

She couldn't stand such a thing, but how could she have thought that she was younger than her and was treated like this, and she couldn't bear it even more?

Naturally, she couldn't have thought about it. After all, she was self-centered and would not consider other people's feelings.

An Ran is not afraid that Li Nian will hate her. Anyway, this girl doesn't hate her, but she will cause trouble for her from time to time, so it doesn't matter if she hates her, she will still cause trouble for her anyway.

Oh no, she is not at home now. She has gone to the city. Even if she hates her, she can't find her trouble. She can only be angry alone, then she has nothing to fear.

But he said that Enron was number one in the city, so there would naturally be rewards. Also, Enron invented solar energy, and now he is giving those experts help to explain the solar energy production process. This naturally requires a salary, and it is impossible to help in vain. Enron accepted all these and asked Those people, don't tell the Li family, lest they have to hand it all over to Grandpa Li and Grandma Li. She also wants to save some money, buy some materials herself, and make some small things, so as not to just read books without practicing, and she can't understand some things. .

Experts all said that she could ask them for any materials she wanted without spending any money. However, they also promised her that they would not tell the Li family about her salary, so that Grandpa Li and Grandma Li would not ask An Ran for money. If an adult asks a child for money, they can't do it anyway, but Grandpa Li and Grandma Li can do it. In order to prevent this kind of thing from happening, they naturally won't say anything.

Although she didn't tell the Li family about her salary, An Ran used her salary to buy some towels, cream, clothes, shoes, school supplies, etc., and gave them to her parents and younger brothers at home, saying that she was filial to her parents.

As for others, Enron will naturally not buy it.

She also told her parents who came to visit her that if Grandpa Li and Grandma Li asked them for it, they should tell them: She is filial to them. If they want it, they should let their children be filial. Unless Uncle Li and the others also want it, Buy something for Grandpa Li and Grandma Li, otherwise, Dad and Mom Li won’t buy it either.

Father Li, Mother Li, and the others had already been heartbroken, so naturally they would not be stupid enough to give the things An Ran bought them to Grandpa Li and Grandma Li.

Grandpa Li and Grandma Li were naturally unhappy when they saw that An Ran was buying things for his parents and brothers, but not for them. He would probably have beaten her again when An Ran was at home. But now, An Ran was in the city. , they couldn't fight even if they wanted to, they could only get internal injuries from anger.

Summer vacation is here. An Ran doesn't have to go to school, so she studies solar energy with Mr. Zhang and the others. After receiving her salary, she has to do something.

At home, An Ran naturally told her father and mother the reason. When they heard that she wanted to study solar energy with the leaders, they naturally would not stop her.

As for Grandpa Li and Grandma Li, I thought that An Ran would come back during the summer vacation and be able to deal with her. Now seeing that she is not coming back and wants to help the experts in Xuancheng, she is naturally angry, but there is nothing she can do about An Ran. After all, They can't stop Enron from studying things with experts.

Therefore, An Ran left the Li family for this reason, so that she no longer had to deal with Grandpa Li, Grandma Li, and the pile of top-notch products in the big house.

With the addition of Enron, solar energy research has naturally progressed rapidly.

In the past two months when I was studying at An Ran, thanks to An Ran's constant guidance, I was working on solar energy. Now that An Ran is directly involved in the research, the progress is getting better day by day. In less than a month, the first set of solar power generation equipment was built. come out.

Of course, this is mainly due to the advanced knowledge of this thing and the full cooperation of the materials, otherwise it would be difficult to make it.

It was a sunny summer day, when the sun was at its best, and the solar energy absorbed throughout the day was enough to power several lights at night, and everyone who saw it couldn't help but be extremely satisfied.

“Not only can we provide lighting at home, but we can also create solar power stations to generate electricity; we can also create solar water heaters to heat hot water, so that people can have free hot water; we can also make solar street lights for use on the road; we can also make solar calculators for small electrical appliances. , solar flashlight, etc." An Ran said.

The principles of solar street lights and other things are not complicated, and experts can understand them, but this solar water heater, although solar water heaters are not available abroad, other types of water heaters have long been available abroad, but they have not been available in China, at least not yet. This After a while, the expert listened to An Ran and said, "Can you make a water heater?"

An Ran nodded and said: "This thing is much simpler than solar power generation. It can be done."

Immediately, he explained the principle to everyone, and everyone secretly thought that although it was not as simple as they thought, it was indeed much simpler than creating solar power from scratch. They immediately said: "This thing is very good. Let's get there." It has also been organized so that ordinary people can use such convenient hot water."

Although solar energy materials are quite expensive, this thing will definitely not be given to the people for free. It will definitely be the same as other things. People will have to buy it with tickets and money, so they are only responsible for making it. Whether the people buy it or not is up to them. Look at the people themselves. Don’t worry about it being too expensive. If the people can’t afford it, they won’t invent it.

Soon, An Ran and others also made a solar water heater.

Once the sample is produced, mass production will be faster. After all, this is the advantage of collective work.

Soon, solar lamps appeared on the market, which were specially used in places without electricity. Considering that large-scale solar power generation equipment was unaffordable for ordinary people, this simple solar lamp appeared. The solar panel was embedded above the light bulb. There is a hook, so you can take it out to dry in the daytime, bring it into the house at night, and hang it on the hook to provide lighting.

It is very popular with people in places without electricity. In addition, the price is not affordable for ordinary people. Many people have bought it for lighting. After all, burning oil is expensive and it is still dim at night. Now that we have this thing for lighting, we don’t need it after buying it. If you buy oil, it will be much brighter than an oil lamp. It will be great to be able to make money doing things at night.

As for solar water heaters, it is difficult for people in the countryside to afford it, and only people in the city can afford it. Although solar energy materials are not cheap, in this era, the country prices various things very low, so people in the city can still afford it. People in the village can afford it if they save for a long time, but most people have stoves to boil water, so they may not spend that much money to buy it.
