Today’s supper is particularly fragrant. I used to eat some cakes, which was almost unchanging. But today I ate it, with such a delicious pie, peach pits, I felt that life was so beautiful.

"After eating, hurry up and do your homework." Yulian said.

Since we are all in school, we must have homework. However, when we heard Yulian's words, Taohe and her sister shook their heads: "Today is the first day, and the teacher has not left homework yet."

On the first day, there were so many kids coming, and the teacher didn't teach any courses at all. Almost all of them were used to maintain order. The most basic rules for teaching primary school students, such as sitting well in class, not running around, and not talking, so it took a whole day. In the end, the teacher had already started to use force to those students who did not perform well, and several children were beaten up.

Since I haven’t learned anything today, of course I will not have homework.

"No, the teacher has no homework, so I have to leave you homework." Lao Liu said: "Copy the first five pages of the textbook for me."

Lao Liu is Gao Huai, and now he is definitely one of the few people with ink in the village. Lao Liu will not waste time watching his children.

From this day on, a tradition has been formed. The teacher keeps one homework and the sixth brother has to keep one homework. In many cases, the sixth brother has more homework than the teacher. Anyway, the sixth brother collects junk and has enough white paper, so it’s enough to nail a few more books.

The sky outside gradually became dark. Yulian pulled the light rope, but the light did not react at all. It was almost the same as before, and it was time for a power outage again.

There are almost no household appliances in the countryside, the main one is electric lights, but it is very depressing. There is electricity during the day, but power outages are often done at night, so the electric lights almost become a decoration. Just like Stephen Chow's flashlight, when the sun shines during the day, it will light up. When there is no light, it will definitely not light up!

At this time, Taohe and Hongxia were still writing on the kang table. Looking at the two children writing, Lao Liu said, "Let's light the light!"

In the past, all kinds of things at home were done before dark before dawn. When it was dark, there was no need to do anything. Just roll onto the kang. After all, if there was no electricity, it would be a waste to light candles. The family didn’t have the money to buy so many candles.

Now that the child is going to school, he must have a lamp. When he heard Lao Liu say that he should light the lamp, the peach pit was still strange. He thought his father was willing to light the candle, but he saw Lao Liu take out something strange.

It was a cylindrical device, about the same size as a can, and it looked very thick. It should be made of steel. There was a stick a foot long on it. There was a bullet-shaped thing on it. This strange thing immediately aroused the curiosity of the peach pit.

"What is this?" Taohe asked. My father didn't answer. He held the thing and hit the ground slantedly. Then, the middle loosened, and the half below fell directly, and it turned out to be two parts!

It was good to separate and open. Lao Liu took out a densely packed piece of plastic cloth from under the eaves. The peach pit thought it was a treasure. When he opened it, he found that it was a stone?

Taohe's curiosity increased greatly. He watched Lao Liu smash the stone with a hammer, then wrapped the remaining ones and put them back to the original place again.

What exactly is this thing? Peach pits are very interested.

Lao Liu put this small piece of stone into the can, and then sprinkled a little water on it. When the water soaked into the stone, you could see the surface of the stone, bubbles were whispering.

Then the can was reassembled, and Lao Liu put the device in a thicker bottle, which just passed over the device that looked like the can, and only the stick was exposed.

The peach pit had its ears raised, and he had already heard the sound of bubbles coming out inside. The gas was coming out through the bullet. It turned out that it was a pipe, and a small hole was also opened in the middle of the bullet.

Lao Liu took out a match, wiped the match with a sneer, and then approached the bullet. The bullet whizzed and fire came out. The flame looked extremely vigorous and bright.

"So amazing!" Taohe shouted, and he was full of curiosity about the things.

"Go into the house!" Lao Liu entered with this treasure, and the room suddenly became brighter, which was definitely much brighter than the 15-watt light bulb.

"This is a calcium carbide lamp." Lao Liu briefly introduced it to you.

In fact, this thing is used in industry, and its scientific name is acetylene gas, which can be used to cut steel plates. It is produced by calcium carbide. Lao Liu received a piece of calcium carbide, and then he imitated others' appearance and asked a blacksmith to make such a thing. Now it is pretty good to use!

This thing soon spread throughout the village, and every household had such equipment. When they lit it at night, the whole room was very bright and quite cheap.

From then on, there is no need to worry about power outages at night, but this thing is obviously unfriendly. I don’t know how many times it has been, because I bowed my head and got too close to doing homework. Tao Huer’s hair was smoked by this flame, and if it is not done properly, this thing might explode.

You know, this thing can cut steel plates, so how high the temperature of the flame is? It is quite dangerous to get close to it.

A small piece of calcium carbide can last for several hours. Taohe was lying on the kang table. After finishing his homework, Lao Liu took it over to check it. He saw that there was no problem, so he nodded with satisfaction.

It was already past eight o'clock in the evening, and several people got on the kang. The extinguishing of the calcium carbide lamp was also given in particular. It should not be blown. If it was blown inside and exploded, it would be a tragedy and the roof could be blown away.

It was also very simple. Lao Liu took the lamp out of the pool, and in a short while, the light bulb went out by itself.

Calcium carbide needs to be reacted when it encounters water. The can is made of two parts. Although it is very tight, it will slowly seep into the water and cause chemical reactions. Now it is pulled out without water and it stops quickly.

The room became dark, and the peach pit was wrapped in his broken quilt and fell asleep happily. His happiness came from the delicious mutton patties. The peach pit had never eaten mutton, and in his eyes it was the best thing.

The night became darker and darker, and the whole earth was shrouded in darkness, and every household fell asleep.
