Chen Xiabai followed Zhang Chengchuan to the forging room, took out an envelope from his pocket and handed it to Zhang Chengchuan, saying, "This is the bonus for the bicycle improvement information you handed over before. Your name has also been reported. Although there are not many rewards, at least someone knows your name."

"It's okay, I didn't expect that I could exchange for other benefits in this time. It would be nice to have a bonus." Zhang Chengchuan said indifferently, and opened the envelope and saw the money inside. He counted and found that it was about thirty yuan, which was not too much.

Zhang Chengchuan also knew that everyone was very poor now, and it was already very good to be able to give himself a bonus of more than 30 yuan, and he was not dissatisfied with it.

"What are you studying recently?" Chen Xiabai said with concern. He was very surprised that his brother-in-law was able to make a bicycle by himself. The improved data of the bicycles he wrote also opened Chen Xiabai's eyes.

Chen Xiabai believed that his brother-in-law was very smart. He had never been serious before, so he was so frustrated with a reputation of being careless, ignorant, and lazy.

I just don’t know what my brother-in-law is going to continue studying after studying the bicycle, and whether to study tractors, trucks, etc.?

"I'm studying wallpapers." Zhang Chengchuan did not hide his second brother-in-law and took out the biology book he had read recently for Chen Xiabai to read.

"Why do you need to read biological books when studying wallpaper? Also, what is wallpaper?" Chen Xiabai looked at the book handed over by Fan's brother-in-law in confusion. Fortunately, the book handed over by Zhang Chengchuan was specially published in the 1950s, otherwise he would have made a joke when he saw the book that was published on the 21st century.

"It's also a bit of a benefit to read more books, right? Biological books, which contain a lot of knowledge about plants, insects, animals, and organisms of various subjects. I find it very interesting," said Zhang Chengchuan.

"Wallpaper is to paste the wallpaper on the wall. The walls in our house are covered in dust. I plan to study the wallpaper and paste it to make it look better in the house." Zhang Chengchuan said.

Chen Xiabai raised his eyebrows, "Don't you plan to continue researching machinery?"

"Let's go through a while, start the research from a simple one. And I plan to change my mood. The bike I made before took me more than two months, so I was a little annoyed."

Chen Xiabai felt helpless when he looked at his brother-in-law. This guy might be so popular for three minutes, and the time limit for paying attention to something is limited.

From the time Zhang Chengchuan gave his cousin the good work of the brick kiln factory and then went home and did nothing, he should have understood that his brother-in-law is such a restless person, not the kind of person who likes to study something unchangingly.

"How many books do you want to read?" Chen Xiabai looked at a bookshelves beside a wall in the forging room, with about dozens of books on it, including mathematics, physics and chemistry, and there should be more than a dozen books on it.

The books Zhang Chengchuan placed here can be released. Mathematics, physics and chemistry were published in the 1950s and 1960s, and biology were similar. Who would report such scientific books? What should he report? He loves learning and science?

Of course, the essential thing on the bookshelf is quotes. That book definitely occupies an absolute position and is a very eye-catching book.

"Have you finished reading all these books?" Chen Xiabai asked at the bookshelf such as mathematics and physics. He was also a little scared when his brother-in-law loved studying so much.

Chen Xiabai thought that after entering the machinery factory, he read books on machinery, and it seemed that he rarely read mathematics, physics and chemistry. Sure enough, he still had to add other knowledge.

Mathematics, physics, chemistry and machinery can also be used. If you learn too much, you won’t be fooled. You will regret not being able to use it until you use it. You will regret that you will not let it happen if you use it.

"Second brother, I'll show you this is a circuit board I made myself, look..." Although Zhang Chengchuan was studying biology and preparing to study wallpapers and how to incorporate silent flowers into wallpapers, other studies have not been left out.

This circuit board was made by himself after reading so many physics books before, especially he found a small light bulb, which was a small light bulb with a low wattage for experiments.

"I follow this circuit board..." Zhang Chengchuan excitedly introduced the circuit board he had studied to his second brother-in-law. He planned to study it and then make a biogas tank and biogas lamp.

It will take a long time for Yunhe Brigade to pull the wires, but Zhang Chengchuan wants to have a lamp, light candles, kerosene lamps and so on, he has had enough, he wants electric lights.

So he also needs to study the biogas lamps and other biogas lamps. Now he has just created a circuit board to observe. When will the lamp be integrated and then try how to make the biogas lamps after it is integrated.

Chen Xiabai was very interested when he saw the circuit board that Zhang Chengchuan made himself. After Zhang Chengchuan connected the positive and negative poles, he became even more interested.

The two were very involved in chatting. Chen Xiayue and Hu Xiaofang and the others chatted for a while and then prepared to cook lunch. They would stay with their second brother to have dinner together later.

Because his second brother came over, Chen Xiayue took out the bacon she had prepared before and prepared a fried bacon for her second brother.

In addition to stir-fried bacon with spring bamboo shoots, Chen Xiayue also took out the braised duck neck and duck feet he made before, and of course he would not take out pickled pepper chicken feet and other things.

I fryed another scrambled egg with tomatoes and fried beans. Chen Xiayue did not continue to cook the four dishes. The portions of the four dishes were very large and I didn’t plan to make them more.

Chen Xiayue did not cook soup because the rice cooked was porridge. The rice with a lot of rice soup did not need to be cooked separately.

"Second brother, Achuan, have dinner." Chen Xiayue prepared the meal and walked to the door of the forging room and shouted.

When Chen Xiayue opened the door, she saw the two of them doing experiments with great enthusiasm. The way she looked like a child who was particularly dedicated to playing with her beloved toy made her teeth so sad.

Pure liberal arts students, especially those who are poor students, do not understand the hobby of boys who love science, love various machinery, physics, etc.

"Second brother, Achuan, have dinner." Chen Xiayue stood at the door and shouted.

"Ah--" Zhang Chengchuan was shocked by Chen Xiayue's shouting, and the circuit was short-circuited, and a spark appeared.

Chen Xiayue: “…”

Zhang Chengchuan was so irritable that he wanted to curse people because of the short circuit of the circuit. When he raised his head and saw Chen Xiayue standing at the door, he choked when he saw Chen Xiayue standing at the door with expressionless face.

"Xia Yue... Is there anything wrong?" Zhang Chengchuan smiled awkwardly. Although he was very angry just now, he was also very guilty when he saw his wife's expressionless look.

"It's time for dinner, when are you going to play?" Chen Xiayue said in a bad tone.

Zhang Chengchuan was very devoted before whether he was studying or doing research. He was almost at the point of forgetting to eat and sleep. She often reminded him that he did not really not eat or sleep.

Although he is usually lazy, he is definitely very devoted when inspiration comes or interest comes. When he doesn't want to study, it's like fishing for two days and drying the net for three days.
