That night, after Lin Yan finished his cultivation, he began to think about what to teach Shi Zhi and them.

Everything has to start from the most basic, mathematics is better to teach, they have mastered the basic algorithms, increase the difficulty a little bit, and start to learn systematically.

The hard part is physics and chemistry, what to teach from scratch.

"Fat Bao, is there any basic textbook to use?"

Fat Bao: "What basic textbooks do you need?" ”

Lin Yan's eyes rolled, there is a question to ask, and you can still make a choice, she said: "I want enlightenment textbooks for people who have zero knowledge of physics and chemistry." ”

Fat Bao: "There are basic chemistry and basic physics, which need to be exchanged for contribution points, 5 contribution points per book. ”

"Really? Is there any basic math? Lin Yan hurriedly asked, only five contribution points, and he could afford it completely.

Fat Bao: "Yes. ”

Lin Yan was happy in his heart, "Where will the exchanged books be?" ”

Fat Bao: "The exchange is a virtual book, which is stored in the core of the science and technology museum, and you can see it from the display screen at any time if you need it." ”

"Will it always be?"

Fat Bao: "It's always there, forever." ”

Lin Yan immediately spent 15 contribution points to exchange for basic textbooks of mathematics, physics and chemistry, and then she saw that there was an icon in the display area of the black crystal ball, which was the three books she had exchanged.

Her mind moved, and the three books were displayed on the big screen, very clearly.

"Fat Bao, open basic physics."

Fat Bao: "Okay, please take a look." ”

Lin Yan browsed it, and it was really the most basic, telling some simple examples, and then going from shallow to deep.

It touches on the basic concepts of weight, volume, etc., then the basic mechanics concepts, and finally the electromagnetism concept.

Lin Yan was very satisfied, this was what she needed most. She thinks that many things are already common sense, but she doesn't know how to explain them.

Nowadays, learning from scratch still requires professional books as a guide to study systematically.

With the teaching materials available, Lin Yan slept satisfied.

The next day, I followed A-Niang to see the situation in the field and helped mow the hay and pile the haystacks.

In the evening, Lin Yan said to Hua Hong: "Auntie, I want to use the room in the middle of the house to teach my friends to learn." ”

"What are you studying?" Hua Hong was stunned, when she was still living in the cave, those children often asked their daughters to study, why did they still have to learn.

"It may take a little longer to learn something new, and they will come to our house more often in the future. A-Niang, do you agree? ”

Learning is a long-term process, and there are more children at home, so I don't know what to think, so I still have to communicate first.

"How long does it take?" Bonus asked. In fact, she is also relieved to have children staying with Lin Yan. Although the family is safe, Lin Yan is still too young.

Lin Yan hesitated, "I'm not sure, it depends on how fast they learn." It could take a few years. ”

"Are you going to eat at our house?"

"No, go back to your own house when you eat."

"That's fine. You have to get along with those children and don't get bullied. ”

Lin Yan smiled and nodded, "A-Niang is so good." They will be grateful to Ah Niang in the future. ”

Hua Hong didn't care about gratitude in the future, she just looked at the moment, and it was good to have a child with Lin Yan.

After eating, Lin Yan went next door to find Ye Ya, proposed that she wanted to organize the child to study, and asked Ye Ya if she was willing to join.

Of course Ye Ya is willing, he is Lin Yan's follower, "Who are they?" ”

Lin Yan said: "For the time being, we will first set on Red Spirit, Shi Zhi, Aquatic Life, Hua Min, Blue Moon, Bai Chen, and you." ”

"Who are Hong Ling, Shi Zhi, and Hua Min?" Ye Ya looked confused, when did there be more of these friends who didn't know each other.

"Haha, it's grass branches, small stones, and flowers, and they have a new name."

Ye Ya immediately said: "I also want to take a new name, well, I want Ye Cong, I'm the smartest." ”

"Okay, good, call Ye Cong." Ye Zi happened to hear it very agreeing, "I have the same surname, and everyone in our family will be surnamed Ye in the future." ”

Mu Shi did not express an opinion on this, the tribe was originally respectful of the mother, and it was normal for the child and the mother's surname to be taken seriously.

Nowadays, every family is basically headed by a woman, and the children are all surnamed by their mothers.

Ye Cong also smiled, "A-Niang, call me Ye Cong in the future, don't call me wrong." ”

"Okay, my son's name is Ye Cong, and A-Niang will call you that in the future." Ye Zi looked at him and Lin Yan with a smile, "There will be more children in the future, you have to protect Lin Yan and don't let her be bullied." ”

Ye Cong puffed up his small chest and promised: "I will definitely protect Lin Yan, whoever bullies her, I will beat her." ”

Looking at his serious appearance and small body, Lin Yan couldn't help but sneer.

"Ye Cong, you are so cute."

Ye Cong frowned, "I'm serious." I am greater than you and can protect you. ”

"Uh-huh, I know you're serious, I won't laugh anymore, okay?"

On September 1st, Lin Yan took a group of children to start a new learning.

In the hall of Lin Yan's house, there is a large stone slab and homemade charcoal.

The children each came with their own stools and their own slate charcoal pens.

The children Lin Yan said were all here, and Shui Sheng could have some twists and turns, but it was the water woman who resolutely supported it, so that Shui Hua agreed.

The other children's families are very supportive, and parents want their children to become as smart as Lin Yan.

The simple classroom made Lin Yan extremely disgusted, but it was already the best he could do.

She glanced at the children sitting obediently and announced earnestly: "From today onwards, I will teach you three subjects, mathematics, physics and chemistry. Let's talk about the rules first, you can't give up halfway when you come, you need to stick to it every day. ”

"There is one lesson in the morning for each subject, and the same is true in the afternoon, and the rest is adjusted according to the learning pace. If you don't understand something, you can ask questions at any time and everyone will discuss it together. ”

The children were eager to try, their eyes wide open, wondering what they were going to learn today.

Shi Zhi was the first to ask, "Which course to learn first?" ”

"Mathematics." Lin Yan turned around and wrote down the four symbols of addition, subtraction, multiplication and division on the slate, and then listed a few simple equations.

"You've learned the ten numbers from 0 to 9, and you know addition and subtraction. Today, we're going to learn about the four most commonly used symbols in math......"

There were eight children in total, and they listened very attentively. The first time I entered the wonderful world of mathematics, before it was just a simple addition and subtraction algorithm, verbal mental arithmetic, they all understood.

When everything is clearly displayed in words and symbols, it is a completely different feeling.

The four basic symbols are understood, and the addition and subtraction operations have a foundation, Lin Yan's middle point in this lesson is the algorithm of multiplication and division, and she listed the ninety-nine multiplication table.

Eight of the more than 3,000 children were selected to learn very quickly.

Lin Yan only spoke once, and they were able to draw inferences.
