Zhang Chengchuan laughed, the power of her beating didn't cause him any harm at all, so he said while laughing, "Didn't I show you a clear path?"

"You are really annoying." Chen Xiayue said while biting on his shoulder.

"Okay, okay, let's ask Ans if there is any."

"I also know that my own problems can definitely be solved by Ans, just buy an oral cleaning product. But, don't I want to do business with netizens in 2020?" Chen Xiayue sighed .

"Then change the prescription with Ans." Zhang Chengchuan said.

"Forget it." Chen Xiayue thought about it and let it go. She should continue to study pharmacology. As for the research and development of new products, she didn't care about it before that time.

After Zhang Chengchuan handed in the information of the oil detector, he did not immediately put it into the research of the next project. Like Chen Xiayue, he felt that his knowledge reserve was relatively small, so he was busy studying.

He had only just begun to learn about biology and chemistry before, and this time he really needed to learn more and more advanced knowledge.

Zhang Chengchuan didn't study for a long time like before, but now he trains with his soldiers every morning when he wakes up, and starts to study after nine o'clock in the morning.

He rests from 9:00 am to 11:30 noon. After lunch, he has a lunch break until 2:00 pm and then learns to 5:00 pm, and after 5:00 is his free time.

In fact, after 5 o'clock, Zhang Chengchuan will give the soldiers a make-up class. After having dinner at six o'clock in the evening, Zhang Chengchuan will continue to teach the soldiers.

Because Zhang Chengchuan wanted to teach the soldiers, he bought a solar lamp. He only needed to absorb solar energy to illuminate a certain area every day, and then he could teach the soldiers.

Chen Xiayue looked at Zhang Chengchuan who hung the solar lamp and asked, "You take out the solar lamp now, have you figured out how to explain it?"

Zhang Chengchuan of solar energy should not be studied yet, right? Nowadays, people either use candles or kerosene lamps, and even if there are electric lamps, there are very few. As a result, this guy took out the solar lamp directly. Have you figured out how to explain it?

"Not yet, I believe these soldiers will help me keep it a secret." Zhang Chengchuan replied while placing the solar panel on the roof.

"So your next research project is solar energy, right?" Chen Xiayue asked Zhang Chengchuan, who hung the solar lamp on the shelf in the yard, looking up at the roof.

"Probably?" Zhang Chengchuan hesitated. "Anyway, I have to study hard in a short time. As for solar energy research, it will take a long time."

"Also, you are indeed not a knowledgeable genius. The most urgent task now is to replenish your knowledge reserve. Otherwise, when the big guys want to communicate with you in the future, it will be bad to find that you are just a sham." Chen Xiayue joked.

"Have you said that about your man? Where am I a sham?" Zhang Chengchuan glared at Chen Xiayue pretending to be angrily, "I am also very talented, although I can't compare with those big guys, But it's not just a **** that's lost in gold and jade."

"Who knows?" Chen Xiayue raised her eyebrows and smiled.

After Zhang Chengchuan and Chen Xiayue hung up the solar lanterns, there was a place where they could make up lessons for the soldiers that night.

Lu Zhanguo had already arranged for his wife and eldest brother. His eldest brother still needed to stay here for a few days before going back. Lu Zhanguo went shopping with his eldest brother, and sent his eldest brother away a few days later. .

Lu Zhanguo is not a native of Yunnan and Guangxi. His hometown is thousands of miles away in the north, and his wife is also in the north. His eldest brother has something to do at home, so it's impossible to stay here with them all the time.

After sending off the eldest brother, Lu Zhanguo told Yu Xiujuan that he still had a task, but because the task was relatively free, he could come back in a few days and let her stay at the family home with peace of mind.

Lu Zhanguo also asked his comrade-in-arms and his boss's wife to help take care of his wife. His wife had just arrived in many unfamiliar places. Moreover, she is from the north, and he was a little worried that she would not be acclimatized when he first came to the south, so he asked his sister-in-law to take care of her.

Of course the sisters-in-law will not refuse.

This boy Lu Zhanguo is young and capable. He has always had a good relationship with their men. He is also polite and polite to them who are sisters-in-law. They all like this young man.

Isn't it just to take care of Lu Zhanguo's wife? What is this?

After settling his wife, Lu Zhanguo returned to the team.

Zhang Chengchuan's tutoring Lu Zhanguo also caught up. Recently, Zhang Chengchuan continued to teach them pharmacology and mechanical knowledge.

The ability of the soldiers to survive in the wild is stronger than that of Zhang Chengchuan, but Zhang Chengchuan's knowledge of mathematics, physics and chemistry is not comparable to the soldiers. Even Lu Zhanguo doesn't necessarily know more than Zhang Chengchuan.

When Zhang Chengchuan was in class, the soldiers listened carefully to the class. He also took care of some soldiers who had a slower learning progress. He spoke in a simple but broad-ranging way. The content he taught was really useful.

Although what he said had nothing to do with the army and the military, it was closely related. Although it is knowledge of physics, soil, biology, chemistry, machinery, etc., but it does not involve the secrets of the military, I am not afraid of what will happen to others after listening to it.

That's why Zhang Chengchuan taught classes in his own yard so openly that occasionally educated youth would come and listen, and other people in the village would also come and listen.

Some of those people in their twenties can understand what Zhang Chengchuan said, and some people don't understand it at all. There are also teenagers and girls who are still reading, so they can understand a little bit.

Zhang Chengchuan's cram school is in full swing every night, and even some illiterate villagers come to listen to it occasionally and can read and even learn to count.

The brigade captain didn't say anything about Zhang Chengchuan's practice. Zhang Chengchuan was tutoring the soldiers and literate the adult villagers by the way. He didn't take the jobs of the teachers of the brigade primary school. Why did he ban it?

Moreover, what Zhang Chengchuan taught is not inaudible. He taught all scientific subjects. If others wanted to report him, they really couldn't find any wrong reason to report the content of his lectures.

Zhang Chengchuan and Chen Xiayue taught the soldiers from time to time, but in fact they were more concerned about their own studies.

Spending about six or seven hours a day studying, and then spending an hour or two teaching others, can be regarded as consolidating your knowledge.
