"This book is not cheap." Jian Yong felt a little distressed when he looked at the book. When he opened it, he almost spurted blood.

It actually says things like one, two, three, people, mountains, and trees, and they're all in abbreviated form.

How to put it, this is basically equivalent to someone in the later generations buying a flagship computer worth 20,000 to 30,000 yuan just to play Lianliankan, but what they play is a castrated version.

"If you have money, burn it!" Jian Yong himself was reluctant to use the Cai Lun paper. When he saw someone wasting it like this, he couldn't help but cursed secretly.

"What I just gave out was Chinese, now I'll give out math."

Okay, this time Jian Yong took a look and didn't understand.

Can anyone help explain what these writhing things like caterpillars are?

Waiting online, I have to go to class later, it's quite urgent.

"Chief Guo Shan, why can't Bei understand this book?" Liu Bei was the first to ask.

"Well, this is the math written by Ma Lang. From today on, he will help you with lessons. If you have any questions, just ask him.

The last book is called Science. You all should know that this is what Ma Lang studied. Now I am giving you some introductory things. If you want to really learn it, you can pass the exam and enter the science class in the future."

"Science?" Liu Bei's eyes lit up, and he was also curious about what kind of knowledge Ma Qiang had learned.

The book arrived quickly. It was a very thin booklet. When I opened it, I saw that there were only a dozen pages.

"What is science? Introduction to chemistry of science, introduction to physics of science, introduction to biology of science, introduction to geography of science, and introduction to social sciences of science."

Liu Bei murmured as he read the table of contents, then eagerly opened it and started reading.

There are many people like Liu Bei. Although Ma Qiang writes in simplified Chinese, these people can't even make a guess at reading it.

"The most ridiculous thing in the world! They actually said that there are extremely small organisms in the world called bacteria, and there is also a kind of virus, and people will get sick if they are infected. What theory is this? You can't see it, how can you prove it?"

"And here, no matter how hard you give the other person, you will also receive the same amount of force. In this way, if someone hits me, I don't have to fight back. If he hits me, I hit him."

"Such ridiculous knowledge, Mr. Guo Shanchang, even if we are hired here, there are things we can do and things we should not do."

Jian Yong looked at it for a few times, but also looked disdainful. He looked at Zhang Fei and saw that Zhang Fei was looking deep in thought. He couldn't help but smile and said, "Is Yide wondering why Mr. Ma would write such a ridiculous article?"

?"

"I think what is said above is correct." Zhang Fei scratched his head and said, "I can't explain clearly, but as for the force thing I just mentioned, when I hit someone, it will naturally hurt, but when I hit

The stone hurts me, but the stone didn’t hit me. I hit the stone, so why do I feel pain?”

"That's not because you hit a rock! The rock is hard, so it will naturally hurt."

"But when I was practicing martial arts, I would feel pain if I hit the water for a long time. Is the water also very hard?"

Liu Bei nodded secretly and said with a smile, "That makes sense. I didn't expect Yide to be so observant. From this point of view, Mr. Ma's science is not without purpose."

Everyone listened to what Zhang Fei said and couldn't help but secretly speculate.

Ma Qiang had told Guo Ping before that if someone didn't want to learn this science, there was no need to force it, so Guo Ping was ready to give up if it was no longer possible, but he didn't expect to be brought back again by Zhang Fei's words.

"You are also scholars. If you know the principle of studying things to gain knowledge, if you have any questions, just ask Ma Lang when he teaches you in the future. Don't be presumptuous here! Okay, let me tell you about the schedule.

and school rules.”

Guo Ping's words made everyone quiet down and continue to listen to Guo Ping's words.

"So, the reason why we can stand on the ground is because there is a gravity sucking us under the ground, and the reason why we can walk is because of friction. It's unbelievable, it's really unbelievable." Jian Yong tilted his head and said with a smile, "Xuande

, we are really right to come here, this knowledge cannot be learned at home."

"Yeah, what I'm most interested in is this chapter of social science. Nations can be divided into marine, farming, nomadic and fishing and hunting according to the main ways of obtaining food. Among them, agricultural people need to guard the fields and work hard to satisfy their hunger, so generally they are not

Due to the difficulty in obtaining food, the other three ethnic groups, such as nomads, are willing to plunder. They are more accustomed to plundering to meet their own needs. This can actually be used to explain why our Han people are so docile and simple, while the barbarians from all over the world are so brave and fierce.

It really makes people feel refreshing. Unfortunately, this book only contains a little bit, and I always feel that it is still unfinished." Liu Bei held the book and read it again and again.

After Liu Bei finished speaking, he looked up at Zhang Fei and found that Zhang Fei was making strange movements.

"Yide, what are you doing?"

"Brother, I always feel that this kind of friction can be used in martial arts. Don't say anything. I'll think about it some more." As he spoke, Zhang Fei seemed to be holding a spear in his hands and making an assassination move.

"There is food, drink, and reading here, but it's a pity that there is no young lady, otherwise it would be perfect." Jian Yong laughed.

"Xianhe...you!" Liu Bei shook his head.

With food, drink, and learning, the still young Liu Bei and others were naturally willing to stay here with peace of mind, and half a month passed in the blink of an eye.

On this day, Liu Bei, Zhang Fei and others were practicing equestrian skills on the road outside the camp. Thanks to Ma Qiang, Liu Bei could finally ride a horse again after leaving Luoyang.

Suddenly, a flying cavalry galloped over. Seeing Liu Bei and others, the knight suddenly pulled his horse to a stop, raised his hands and asked, "Brothers, do you know where Mr. Ma Qiangma is?"

"Are you looking for Mr. Ma? Who are you?" Zhang Fei asked as he looked at this man who was dressed in a dusty suit and wore official boots only for military attachés.

"I am Zhang Sheng, the county lieutenant of Jixian County. Mr. Xunma has something important to ask of me. It affects the lives and deaths of hundreds of thousands of people. Please tell me quickly!" Zhang Sheng was already anxious to draw his sword.

"It turns out to be Captain Zhang. Since you have something important to do, I would like to lead the way. Please come with me."

"Thank you. I don't know your name yet."

"My Excellency Liu Bei and Liu Xuande are temporarily the teachers of the Red Star Academy." Liu Bei replied and rushed to the Red Star Camp with Zhang Sheng.

Arriving at the Red Star Camp, Yan Rou was on duty today. He saw Liu Bei bringing someone back, waved the sergeant to be alert, and then shouted, "Mr. Xuande, who is behind you?"

Zhang Sheng took off his hat and shouted, "I am Zhang Sheng of Jixian County, and I am here to see Mr. Ma."

Yan Rou also met Zhang Sheng and said, "It turns out to be County Captain Zhang. I'm going to inform Mr. Xuande. I see that County Lieutenant is very busy with work. You can take Captain Zhang to the restaurant to have something to eat first."

"

"Okay, please report it as soon as possible. This matter is extremely urgent!"
