Pei Lin wanted to tease Feng Jing, but ended up watching it. He was so absorbed that he forgot to call Feng Jing and watched with relish.
As a result, Feng Jing's hand got sore from writing. She stopped writing and raised her hand and shook it, and it hit Pei Lin. She was startled, turned around quickly and looked behind her, and saw Pei Lin standing quietly behind her.
.
Feng Jing was so angry that she raised her hand to hit him: "You know, people are scary to death, you know? Come in and make some noise."
Seeing that their mother was frightened, the four little guys stared at Pei Lin unhappily.
Dabao stood up quickly: "Mother, it's our fault. Next time my father comes again, I will be the first to speak out."
Erbao nodded vigorously.
Sanbao explained: "Mother, we originally wanted to call you King Father, but King Father wouldn't let us."
Huh, my father is still booing, just like a child.
Xiao Sibao rolled his eyes at Pei Lin. He used to think that his father was very cold, but now he realized that his father was very childish.
Feng Jing was angry with Pei Lin, but seeing the four little guys blaming themselves, she quickly said, "It's okay. Mom was so absorbed in writing that she didn't notice the shock. It's okay."
"But if your father does this again in the future, we won't let him enter Yuehuayuan."
The four little guys immediately nodded vigorously in agreement: "Okay."
Pei Lin immediately apologized: "Don't be angry, Jingjing, it's all my fault."
After he finished speaking, he pulled up a chair and sat down next to Feng Jing, stretched out his big hand to take Feng Jing's hand, rubbed her wrist, and asked while rubbing it.
"What you wrote is fat-picking."
"Yes, I thought about it carefully. In fact, alkaline soil is also suitable for growing sorghum and wheat. Wheat and sorghum are grown in Youzhou, but the yield does not seem to be high. I think this is because the soil is not fertile enough, so I thought
To dig out fertilizer, teach people how to dig out fertilizer and make the land fertile, which will increase the yield of sorghum and wheat."
Pei Lin immediately nodded: "That's okay. When the time comes, this method of peeling fertilizer will be distributed to all counties. If the people learn to peel fertilizer, they will definitely increase production."
Fengjing nodded: "Yeah."
Pei Lin and Feng Jing stopped talking about this matter and talked about the suggestions of the previous gentlemen that they would send people up the mountain to find potato and sweet potato seeds tomorrow.
Fengjing had a confused look on her face. She bought the potatoes and sweet potatoes from the system. I'm afraid they don't have them on the mountain. It would be a waste of time for them to go up the mountain to look for them.
Feng Jing said softly: "These things are not so easy to find."
After she finished speaking, she looked at Pei Lin and said, "Actually, I was able to find it because I was lucky."
Pei Lin suddenly remembered that Feng Jing had brought people up the mountain to collect herbs for him, and found several rare medicinal materials at once.
He immediately believed Feng Jing's statement.
"Can Jingjing go up the mountain with us tomorrow?"
Fengjing blinked. She wanted to stop him, not accompany him up the mountain. There was no way to buy potatoes and sweet potatoes in the system. How could she find them?
But seeing Pei Lin looking at her eagerly, she couldn't think of a way to refuse.
Fengjing had no choice but to agree: "Okay, then I will accompany you up the mountain to look for him tomorrow."
After hearing this, the four little guys immediately ran over excitedly: "Mom, can we accompany you up the mountain to look for her?"
Feng Jing looked at the four little guys who were looking forward to her. What could she do? She could only agree.
She decided that at best she would get some other things that could be planted tomorrow.
"Okay, let's go up the mountain together tomorrow. Now you go back and go to sleep."
The four little guys just finished the math problems, stood up, picked up the math notebook, and handed it to Feng Jing: "Mom, help us check if it is correct. If it is correct, we will go to bed."
Fengjing reached out and took it for inspection.
On one side, Pei Lin subconsciously reached out to take the math book from Erbao's hand.
Feng Jing subconsciously wanted to stop him, but soon thought that Pei Lin often came to Yuehuayuan now, and she couldn't hide this for a long time, so she decided not to stop him.
Pei Lin originally wanted to read the Erbao arithmetic problem, but was stunned when she saw it and couldn't understand it for a long time.
He turned around and looked at Fengjing, who was correcting Dabao's arithmetic problems without changing her expression. Then he looked at the three treasures and the four treasures.
I found that the arithmetic problems in the hands of the little ones were all the same, but they were obviously different from the arithmetic calculations they were currently using.
It seems that what the young masters learn is simpler, but he has never seen this.
Pei Lin subconsciously looked at Feng Jing on one side: "I don't think I've seen this Jingjing before."
Feng Jing nodded: "It's a new arithmetic, it's very simple and convenient."
As soon as Fengjing opened her mouth, Sanbao said happily: "This is very powerful, especially Xiao Sibao. He is very good at mental arithmetic. He can do it mentally without using a pen."
Pei Lin looked at the book, confused, and subconsciously looked at Xiao Si Bao: "Is it true?"
Little Si Bao straightened his chest: "Father, if you don't believe me, you can take a test on me."
Pei Lin thought about it and came up with an arithmetic problem. As a result, the four treasures used multiplication and calculated it in the blink of an eye.
Pei Lin was shocked now and looked at Si Bao in surprise: "How did you calculate it? This is too fast."
Xiao Sibao said with a smile: "My mother taught us to memorize the oral formula of multiplication and division. I can calculate it easily by using this."
"Oral formula for multiplication and division?"
Pei Lin knew that this must be the mathematics that Feng Jing learned from her dreams, which was more advanced than their current arithmetic.
Pei Lin stared at Feng Jing with compelling eyes: "I also want to learn, Jingjing, can I teach this to the people of Youzhou? I feel that it is much easier to learn this."
Academic calculation is too difficult for ordinary people, but this seems to be easier to learn.
Feng Jing raised her eyebrows and looked at Pei Lin and said, "You can teach, but how do you tell others about it?"
Pei Lin immediately expressed his position: "You teach me first, and I have learned it, and then I teach a few gentlemen. The gentlemen have disciples, and let them teach the people of Youzhou. When the time comes, you will tell me what you have studied, and you
What do you think?"
Feng Jing thought about it and felt that it would be feasible to teach this simple arithmetic to the people, because simple arithmetic is indispensable in daily life. If the people learn it, they can be hawkers, do business, or even farm.
count.
However, she agreed to publicize this arithmetic, but disagreed with Pei Lin's statement. She had no face to bear this reputation.
"It's better to say that I got a strange book and learned it from the book."
"OK."
Pei Lin quickly nodded in agreement. He looked up at the four little guys and said, "Son, when you have finished your studies, go back to sleep. Father wants to learn arithmetic from your mother."
The four little ones are indeed a little sleepy. After studying for a day and doing arithmetic problems in the evening, their eyelids are now clenched.
However, the four little guys did not forget to warn Pei Lin: "You are not allowed to bully mother."
Pei Lin immediately promised: "Father, I promise not to bully your mother."
The four little guys turned around and left after hearing Pei Lin's promise. Pei Lin looked at Feng Jing with a smile: "The four little guys will definitely be filial to you in the future. You didn't raise them in vain."
Feng Jing smiled and said: "I raise them just to make them upright people, not to be filial to me."
This statement was very different. Pei Lin stared at Feng Jing. Feng Jing didn't want to discuss this topic and quickly spoke.
"Don't you want to learn arithmetic? Let's get started. The first thing we need to learn is the various symbols in arithmetic. Your Majesty, please quickly take a piece of paper and write it down."
Pei Lin immediately listened carefully to Feng Jing's lecture on arithmetic problems, which lasted for an hour and a half.
Feng Jing was worried that Pei Lin wouldn't be able to remember it, so she stopped and said, "Okay, that's all for today. Your Majesty, I'll memorize it more when I get back. Once these symbols are memorized, we'll learn the numbers again."
Pei Lin was very excited. He didn't hate learning these at all, but was very interested. However, seeing that it was getting late at night and Feng Jing was getting sleepy, he had no choice but to stop.
However, Pei Lin was a little reluctant to leave. Looking at Feng Jing, she asked tentatively: "Should I stay tonight?"
