survival in the wilderness

Chapter 44
That night, after Lin Yan finished training, he began to think about what to teach Shi Zhi and the others.

Everything has to start from the most basic. Mathematics is easier to teach. They have already mastered the basic algorithms. Just increase the difficulty a little and start learning systematically.

What is difficult is physics and chemistry, starting from scratch, what to teach.

"Pang Bao, do you have any basic teaching materials?"

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

Lin Yan rolled her eyes. It is reasonable to ask such a question, and she can still make choices. She said, "I want enlightenment textbooks for people with zero foundation in physics and chemistry."

Fat Bao: "There are basic chemistry and basic physics, you need to exchange them with contribution points, 5 contribution points per book."

"Really? Do you have basic mathematics?" Lin Yan asked hurriedly, only five contribution points, completely affordable.

Fat Bao: "Yes."

Lin Yan felt happy, "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 on the display screen whenever you need it."

"Will it always be there?"

Fat Bao: "Always there, forever."

Lin Yan immediately spent 15 contribution points in exchange for the basic textbooks of mathematics, physics and chemistry. 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 for. .

With a thought, the three books were displayed on the big screen very clearly.

"Pang Bao, open the basic physics."

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

Lin Yan browsed through it, and it really was the most basic. What he talked about were some simple examples, and then he went from the simple to the deep.

It involves basic concepts such as weight and volume of matter, then basic mechanics concepts, and finally mentions the concept of electromagnetism.

Lin Yan is very satisfied, this is what she needs most.She felt that many things were already common sense, but she didn't know how to explain them.

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

Now that the textbook was ready, Lin Yan fell asleep satisfied.

The next day, I followed my mother to see the situation in the field, and helped mow the grass and piled the haystacks.

At night, Lin Yan said to Hua Hong, "Aniang, I want to use the room in the middle of my house to teach my friends."

"What are you studying?" Huahong was taken aback. When they were still living in the cave, those children often asked their daughters to study, so why did they still want to learn.

"Learning some new things may take longer, and they will come to our house often in the future. Aniang, do you agree?"

Learning is a long-term process. There are too many children in the family. I don’t know what Huahong thinks, so I still need to communicate first.

"How long?" Huahong asked.In fact, she felt more at ease when she had children staying with Lin Yan.Although the home is safe, Lin Yan is still too young.

Lin Yan hesitated, "I'm not sure, it depends on how quickly Ye Ya and the others learn. It may take a few years."

"Dining at our house?"

"No, we go back to our homes during dinner."

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

Lin Yan nodded with a smile, "Niang is so kind. They will be grateful to her in the future."

Huahong doesn't care about being grateful in the future, she only cares about the present, as long as there is a child to accompany Lin Yan.

After dinner, Lin Yan went to the next door to find Ye Ya, and proposed that she organize children's study, and asked Ye Ya if she would like to join.

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

Lin Yandao: "Temporarily, let's decide on Hong Ling, Shi Zhi, Shui Sheng, Hua Min, Lan Yue, Bai Chen, and you."

"Hong Ling, Shi Zhi, who is Hua Min?" Ye Ya was stunned, when did these little friends whom he didn't know become more.

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

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

"Okay, okay, it's good to be called Ye Cong." Ye Zi just heard that he agreed very much, "It has the same surname as mine. From now on, everyone in our family will be named Ye."

Mu Shi does not comment on this. The tribe respects the mother, and it is normal for children and mothers to have last names.

Now every household is basically a woman as the head of the household, and the children follow their mother's surname.

Ye Cong also laughed, "Aniang, call me Ye Cong from now on, don't make a mistake."

"Okay, my son's name is Ye Cong, and my mother will call you that from now on." 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, don't let her be bullied."

Ye Cong puffed out his small chest and promised: "I will definitely protect Lin Yan, and I will beat anyone who bullies her."

Seeing his serious appearance and small body, Lin Yan couldn't help but chuckle.

"Ye Cong, you are so cute."

Ye Cong frowned, "I'm serious. I'm older than you and can protect you."

"Well, I know you're serious, so I won't laugh, okay?"

On September [-]st, Lin Yan led a group of children to start a new study.

In the main room of Lin Yan's house, there was a large stone slab and homemade charcoal pencils.

The children arrived here with stools and their own slate charcoal pencils.

The children Lin Yan mentioned were all here, and Shui Shengneng had some twists and turns. It was Shui Pozi who firmly supported Shui Hua, so Shui Hua agreed.

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

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

She glanced at the children who were sitting obediently, and seriously announced: "From today on, I will teach you three subjects, mathematics, physics and chemistry. Let me talk about the rules first, you can't give up halfway when you come, you need to persevere every day .”

"Each subject has one class in the morning, and the same in the afternoon, and the others are adjusted according to the progress of the study. If you encounter something you don't understand, you can ask questions at any time, and everyone will discuss it together."

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

Shi Zhi was the first to ask, "Which subject 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 calculation formulas.

"You have already learned the ten numbers from 0 to 9, and you also know addition and subtraction calculations. Today, let's learn the four most commonly used symbols in mathematics..."

A total of eight children listened very engrossed.It was the first time they entered the wonderful world of mathematics. Before that, they only understood simple addition and subtraction, verbal and mental arithmetic.

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

Now that I know the four basic symbols, I already have a foundation for addition and subtraction. Lin Yan's class focuses on the arithmetic of multiplication and division. She listed the ninety-nine multiplication table.

The eight children selected from more than 3000 children are really fast in learning, and they can learn a little bit.

Lin Yan only said it once, and they could infer other cases from one instance.
