Scholars in the courtyard

It was late at night, and the cold wind was howling outside.

It was the end of the year again, and the snow in the sky was reveling again.

In the house, the coal in the heating furnace was about to burn out. Yang Xiaotao slowed down the beauty in his arms, kissed her sleeping forehead, covered her with a quilt, put on his clothes, got up and went to the stove.

He changed a coal ball with the fire tongs, and the fire was burning.

Then he went back to the house and lay down in the quilt.

Then he opened the personal attribute panel.

He looked at the credits, which were still more than 30,000, and then looked at the system's exchange column and found that there was nothing good.

But Yang Xiaotao was still looking forward to this weekend.

Because this Sunday happened to be the end of the month, and the first day of 68, that is, New Year's Day, happened to be Monday.

In other words, at midnight on Sunday, the exchange column was refreshed.

This is not only a weekly refresh time, but also a monthly, or a year. If it follows the system's rules, if it doesn't refresh out a good thing, then there must be something wrong with the system.

So, Yang Xiaotao saved the credits and waited for that day to come.

However, 30,000 credits is still a lot of money.

Last time, because of my eagerness, I only unlocked Chemistry Mastery and got an element symbol pen.

If I had this kind of pen that can automatically judge right and wrong in my previous life, the college entrance examination would not be so difficult.

However, the first level of Chemistry Mastery requires 2,000 credits, while the second level requires 5,000 credits.

This is much more expensive than Steelmaking Mastery.

But there is a reason for being expensive.

At this moment, Yang Xiaotao is hesitating whether to upgrade to the second level.

With his familiarity with the system, the more credits he needs, the better things he will get.

Just like hard work and harvest, the more credits you earn, the richer the harvest.

He looked at the credits again, then looked at Chemistry Mastery, and then put it on his wife's hips, silently saying to his wife, "Wife, give me good luck."

"System, upgrade Chemistry proficiency to level 2."

"Ding! Does the host need to consume 5,000 credits to upgrade the sub-skills and Chemistry proficiency to level 2?"

"Sure enough, it's expensive."

"Yes!"

"Ding, congratulations to the host, the Chemistry proficiency level has been upgraded, the current level is level 2."

"Ding, congratulations to the host, the ultra-pure silicon production process has been obtained."

The next second after Yang Xiaotao confirmed it, the familiar feeling appeared again.

The credits on the system changed rapidly from left to right like quicksand, and finally reached the number 26528, and at this moment a torrent also appeared in the mind as the credits disappeared.

In an instant, Yang Xiaotao felt countless knowledge filling his mind.

What about the amount of substance, mole, Avogadro constant, atomic structure, molecular structure, redox reaction, reaction rate and chemical equilibrium, etc.

These theoretical knowledge are like the deep memories in the mind being dug out and then imprinted in the mind one by one.

It's like these things were originally his.

It's just that the impression is more profound now.

Yang Xiaotao also knew that these were just theoretical knowledge, and some of them were just to remember to do so, but he didn't understand why they were done this way.

And there was still a long way to go before he could apply them in practice.

However, these were not problems. This was the second-level chemistry mastery. As long as he was willing, the third and fourth levels would be a matter of minutes.

At that time, he didn't believe that with the enlightenment of the system, he couldn't be a chemist?

Then there was another reward.

A reward that made Yang Xiaotao feel that the five thousand credits were worth it.

He was even a little excited, and he reached out to hug his wife in his arms, thanking his wife for the good luck she brought him.

Ultra-pure silicon production process.

This is a very important semiconductor material.

In his previous life, Yang Xiaotao came into contact with computers in junior high school, and at that time he often heard people talking about Silicon Valley.

Then he knew what silicon was.

At that time, he naively thought that it was just some stones.

There were many stones by the river in the village, and he could find a bunch of them of any size and color.

But when I was older and in high school, I realized that stones are still the same stones, but silicon is an element in stones.

When I went to college, I could clearly distinguish between stones and silicon.

After a deep understanding of this silicon, I understood why it is called Silicon Valley.

That is to study stones to the atomic level, no wonder they are so powerful.

However, now that I have the production process of ultra-pure silicon, I may not be able to study stones thoroughly, and then I can establish a Silicon Valley, Silicon Slope, and Silicon Mountain.

Thinking of this, Yang Xiaotao hugged the koi in his arms and fell asleep.

It was so cold, but it was still warm in the quilt.

The next day, just after dawn, Yang Xiaotao felt something around him, and then he opened his eyes and saw Ran Qiuye getting dressed.

"It's still early? Lie down for a while."

Yang Xiaotao sat up, but Ran Qiuye shook his head, "I can't sleep, get up and tidy up."

He felt something strange in his mouth while speaking, and glanced at Yang Xiaotao and then went out to wash.

Yang Xiaotao grinned when he saw his wife rolling her eyes at him.

His wife is the cutest thing about her.

She did everything, but she still looked tough.

After Ran Qiuye left, Yang Xiaotao couldn't sleep, so he just sat on the bed and checked the system panel.

"It's time to eat hot pot."

Seeing the exchange bar, which was full of hot pot ingredients, Yang Xiaotao wondered whether he should invite Huang Lao and Xia Lao to eat hot pot some other day.

After all, it's winter, eating hot pot, drinking and chatting is the most suitable.

Looking at the things in the system space, there are 80 kilograms of meat rewarded every month, and a lot of vegetables. It's impossible to eat them at home on weekdays, so it's just right to find time to get together.

"Well, this is possible."

Thinking of the matter of the Nine Departments, Yang Xiaotao felt that it should be put on the agenda.

Putting away the panel, Yang Xiaotao closed his eyes and rested, and then sorted out the gains of last night in his mind.

First, the second-level chemistry mastery. In Yang Xiaotao's opinion, the content of this indoctrination is the content of inorganic chemistry.

In his previous life, Yang Xiaotao remembered that when he was in college, this was a class that he took a semester to take.

And it was an extension of basic chemistry.

Now, the systematic indoctrination starts from the most basic periodic table of elements, and then goes deeper little by little. It contains a wide range of content. If he had not received several indoctrinations before, this time alone would be enough for him to have a good sleep.

But this time, he really gained a lot.

I read the correct version in the 16-9 book forum!

Thinking of this, he checked the production process of ultra-pure silicon.

Just like the aluminum alloy production process obtained before, how to do it and how to do it are explained clearly.

In other words, as long as you do it according to this, you can make ultra-pure silicon.

However, to do it according to this, you also need matching raw materials and matching production machines.

If it was before, Yang Xiaotao might not understand the reaction inside, but with the chemical knowledge indoctrinated by the system, these process requirements are clear.

"The next target of this chemical plant has been found!"

Yang Xiaotao got up happily, but he still said, "I have to find some chemistry books to read, at least it can't be too abrupt."

But in a blink of an eye, I thought of the books I needed to read, including radar, aerodynamics given by Mr. Qian, and now a chemistry book. I always feel that there is not enough time.

"Sitting in the position of a big leader, there should be a lot of time."

Thinking so, Yang Xiaotao went out refreshed, and then saw Ran Qiuye brushing his teeth and rinsing his mouth.

Yang Xiaotao walked up to him and picked up the toothbrush, and the two of them washed side by side.

"There may be social events in the next two days."

Ran Qiuye naturally understood what Yang Xiaotao meant. After all, people in high positions always have to socialize.

I just didn't expect that my man would start to enter the social circle at such a young age.

The two prepared breakfast, and Comrade Lao Jin and Lao Dao came back from a walk outside, holding fried dough sticks and twisted dough sticks in their hands.

"This fried dough twist is really delicious."

Old Jin came up to him and said, "The restaurant in the south of the alley just opened. It was open when I went there, so I brought back a few and let the children taste them."

The old Taoist rolled his eyes at the side. What did he mean by just walking over and opening the door? He obviously went there on purpose and waited for almost half an hour.

Yang Xiaotao didn't expose it when he saw it, and hurriedly took it into the house.

After a while, the children got dressed and got up to eat. There were a lot of people at the table, and it was lively to eat.

It was also thanks to the supplies donated by the system every month.

What pork, beef, mutton, vegetables and fruits, cotton cloth tickets, eggs and grains, if they were not available every month, it would be a headache for the two of them to satisfy so many mouths with only the salary of two people.

Not to mention that there are elderly people to take care of and a litter of dogs to raise.

After dinner, Yang Xiaotao went out to work.

Just after passing the hanging flower gate, a figure walked in and almost bumped into Yang Xiaotao.

Looking closely, who else is it but Sha Zhu?

At this time, Sha Zhu was panicking and anxious, panting heavily, and sweating on his forehead in the cold weather, looking like he was chased by a dog.

When Sha Zhu saw Yang Xiaotao, he was also stunned, and a trace of struggle flashed across his face.

However, Yang Xiaotao just took a look and didn't mean to stay, and walked out the door.

Seeing that Yang Xiaotao ignored him, he felt resentful in his heart, but it was soon replaced by worry, and he ran to the house of the aunt.

Many workers in the yard were about to go out, and they also saw Sha Zhu running in. Although they were surprised, it was better to have less trouble than more, and out of sight, out of mind.

Sha Zhu ran to the door of the aunt, who was cooking steamed bread at this time. Xiaodang and Huaihua were still covered with quilts on the kang. It was cold outside, so it was better to stay at home.

"Zhu Zi?"

The aunt was surprised to see the figure running in, and when she saw it clearly, she immediately showed surprise, "You"

"Auntie, help me!!!"

On the other side, Yang Xiaotao drove to the machinery factory.

She greeted the workers on the way and then came to the office.

Lou Xiao'e saw a kind of awe on Yang Xiaotao's face that she had never seen before.

This was her father's warning. Even if she had a good relationship with Yang Xiaotao, she couldn't be disrespectful.

Moreover, their family situation was special, so she couldn't ask around or spread rumors.

This was a taboo.

Therefore, Lou Xiao'e was more careful and respectful at work.

"Boss Yang, this is the situation of the factory in recent period."

Lou Xiao'e put the documents on the table, and Yang Xiaotao sat down in a good mood.

"What are the important matters?"

Yang Xiaotao asked habitually, and Lou Xiao'e immediately took out several documents on it.

"This is from the Red Star Steel Plant. Several of their blast furnaces need to be shut down for recovery, which may affect production. Ask when they can be repaired."

"This is the news from the pharmaceutical factory. There are still two main production machines missing for artificially synthesized bovine insulin. I hope we can help solve it."

"This is."

After Lou Xiao'e finished speaking one by one, Yang Xiaotao placed the important ones in front of him, and then picked up the first one, "The steel plant still focuses on safety. Consult with the workshop to reduce the task arrangement in the near future, which is also a good opportunity for the workers to have a rest."

"Talk to Lao Yang about this."

Lou Xiao'e nodded.

"Regarding the pharmaceutical factory's machinery, let Director Zhang go and see what kind of machinery is needed. If it can be purchased, then purchase it. If it cannot be purchased, then write down the machine's performance and style and we will try to make it."

"Okay."

"The welfare of the Yanzhou branch is the same as that of other branches. There will be no adjustment. Please ask Deputy Director Chen for specific arrangements."
