"It's not cheap." Jian Yong looked at this book and felt a little distressed, and when he opened it, he almost spurted blood.

What is written on it is actually one, two, three, people, mountains, wood, and other things, and they are all in shorthand.

How to say it, this is basically equivalent to someone in later generations buying a flagship computer worth 20,000 or 30,000 oceans in order to play Lianliankan, and playing the castrated version.

"There's money to burn!" Jian Yong himself was reluctant to use this Cai Lun paper, and when he saw someone wasting it like this, he couldn't help but scold secretly.

"I just sent it in Chinese, and now I send it in mathematics."

Yes, Jian Yong didn't understand it when he glanced at it.

Can anyone help explain what these caterpillars are writhing around?

Waiting online, waiting for the next class, it's quite urgent.

"Guo Shanchang, why can't you read this book?" Liu Bei was the first to ask.

"Well, this is the number technique written by Ma Lang, from today onwards, he will help you with the class first, and ask him when you have any questions.

Finally, this book is called science, you should all know that Ma Lang is learning this science, and now I will send you some introductory things, if you want to really learn, you can enter the science door after the exam. ”

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

The book soon arrived in my hand, it was a very thin booklet, and when I opened it, 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, introduction to social science of science."

Liu Bei muttered a look at the catalog, and then couldn't wait to open it and read it.

There are many people like Liu Bei, although Ma Qiang writes simplified characters, but these people can even read it with guesswork.

"What a joke in the world! What kind of theory does it say that there is an extremely small creature in the world called bacteria, and there is another called a virus, and people who are infected with it will get sick? I can't see it, how can I prove it? ”

"And here, how much force to give the other party, how much force will be received by yourself, so I don't have to fight back when others beat me, if he hits me, I will beat him."

"Such ridiculous learning, Guo Shanchang, even if we are hired, we still have something to do and something not to do."

Jian Yong glanced at it a few times, and he also looked disdainful, he looked at Zhang Fei, but saw Zhang Feizheng's contemplative expression, and couldn't help laughing, "Is Yide thinking about why this Mr. Ma would write such a ridiculous article?" ”

"I think that's right." Zhang Fei scratched his head and said, "I can't say clearly, but just what kind of force I just said, I hit people, people naturally hurt, but I hit stones, and it hurts me, but the stones didn't hit me, I hit the stones, so why do I hurt?" ”

"It's not because you're hitting stones! The stone is hard, and it naturally hurts. ”

"But when I practiced martial arts, I would feel pain when I hit the water surface for a long time, is the water also very hard?"

Liu Bei nodded secretly and said with a smile, "That's reasonable, I didn't expect Yide to be so subtle, so it seems that Mr. Ma's science is not untargeted." ”

Everyone listened to what Zhang Fei said, and couldn't help but secretly figure it out.

Ma Qiang had told Guo Ping before that if someone didn't want to learn this science, they didn't have to force it, so Guo Ping was ready to give up if he couldn't do it, but he didn't expect to be brought back by Zhang Fei's words.

"You are also scholars, when you know the truth of learning from things, if you have any doubts, you will ask him when Ma Lang teaches you a lesson in the future, don't be presumptuous here! Okay, so I'm going to tell you about the schedule and the rules of school. ”

Guo Ping's words quieted everyone down and continued to listen to Guo Ping.

"So, we can stand on the ground because there is a gravity in the ground that sucks us in, and we can walk because there is friction, which is incredible, it is really incredible." Jian Yong tilted his head and said with a smile, "Xuande, we really came here to come to the right place, this kind of knowledge can't be learned at home." ”

"Yes, what I am most interested in is this chapter of social science, which can be divided into marine, farming, nomadic herding, and fishing and hunting according to the main way of obtaining food, among which the farming people are generally reluctant to plunder because of the need to watch over the countryside and work hard to satisfy their stomachs, and the other three peoples such as nomads are more accustomed to plundering abroad to meet their own needs because of the difficulty in obtaining food. It is really refreshing to be able to explain from this perspective why my Han people are so docile and simple, and how brave and ruthless the barbarians are from all directions. It's a pity that this book is only a little bit written, and I always feel that I can't get enough of it. Liu Bei held the book and read it again and again.

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

"What are you doing?"

"Big brother, I always feel that this friction can be used in martial arts, don't speak, I'll think about it again." As he spoke, Zhang Fei seemed to be holding a spear in both hands and making an assassination move.

"There is food, some drinking, and books to read, but unfortunately there is no little lady, otherwise it will be complete." Jian Yong laughed.

"Kenwa... You! Liu Bei shook his head.

There is food, drink, and learning, and for Liu Bei and others, who are still young, they are naturally willing to live with peace of mind, and half a month has passed in a blink of an eye.

On this day, Liu Bei was practicing equestrianism with Zhang Fei and others on the road outside the camp, and Liu Bei was finally able to ride a horse again after leaving Luoyang.

Suddenly, a flying horse galloped over, and when he saw Liu Bei and the others, the knight pulled his horse to a halt and asked, "A few brothers, do you know where Mr. Ma Qiangma is?" ”

"Are you looking for Mr. Ma? Who are you? Zhang Fei looked at this person dressed in dust and dust, and wearing official boots that only military attaches have, so he asked.

"I am Zhang Sheng, the county lieutenant of Jixian County, Mr. Xunma has something important to ask for, it is related to the life and death of hundreds of thousands of people, please tell me quickly!" Zhang Sheng was already anxious to draw his knife.

"It turned out to be County Lieutenant Zhang, since there is something important, I am willing to lead the way, please come with me."

"Thank you, I don't know the name of Brother Tai yet."

"Liu Bei Liu Xuande is temporarily the gentleman of the Red Star Academy." Liu Bei replied, and then took Zhang Sheng to the Red Star Camp.

When he came to the Red Star Camp, Yan Rou was on duty today, he saw Liu Bei bring one person back, waved his hand to put the sergeant on guard, and then shouted, "Mr. Xuande, who is behind you?" ”

Zhang Sheng took off his hat and shouted, "I'm Zhang Sheng from Jixian County, and I'm here to see Mr. Ma." ”

Yan Rou also met with Zhang Sheng, and arched his hand and said, "It turned out to be County Lieutenant Zhang, I'll go and inform Mr., Mr. Xuande, I see that County Lieutenant is in the dust, you can take County Lieutenant Zhang to eat something in the restaurant first." ”

"It's okay, please report it as soon as possible, this matter is urgent!"

"Don't worry, I'll go."
