Qin asked

From Handan in the state of Zhao to Xianyang in the state of Qin, in modern times it is only from Hebei to Shaanxi, with Shanxi in a parallelogram in between. It only takes a few hours to take the high-speed rail, even if you want to come here It is more than enough to drive a car for three days if you want to go on a self-driving tour.

But this is ancient times... Let alone high-speed rail cars, it doesn't even have a decent road!

What is trekking?That is, when you encounter obstacles on land, you have to carry the carriage to overcome hardships... Mo Dou can no longer tell whether it is the carriage carrying people or the people carrying the carriage.

So, after experiencing the people-carried carriage that subverted the three views, Mo Dou even felt that the crazy vibration of the carriage was nothing to worry about... Just kidding, you can try the feeling of riding a bumper car for a whole day, it can make you cry.

Mo Dou understands why so many ancient people died on land, and wrote so many homesick poems, it was because of these roads!

However, even if riding in a carriage is so painful, it is still more comfortable than walking on foot. Mo Dou couldn't bear to see how many scars were scratched on the bodies of those followers and servants by the branches on the road, and those servants walked all day wearing straw sandals. Dozens of miles away.

The Red Army is not afraid of the difficulty of the expedition, thousands of rivers and mountains are just waiting...

Mo Dou thought that he didn't have such courage and spirit, so he could only cowardly stay in the carriage with Ying Zheng to discuss Qin's affairs.

"Dou Ke knows how Qin is doing?"

"My lord, don't worry too much, King Qin doesn't have many heirs..."

King Zhuangxiang of Qin really doesn’t have many sons, only Yingzheng and Chengyu. Chengyu’s presence is not high. His ability is not strong. In the later period, Qin Guoqiang became like that. He was able to betray Qin and subdue Zhao. I don't know how he did it. In short, this achievement is nothing to fear.

However, this reason cannot be used for comfort. Mo Dou held onto the strings of the car and tried to maintain his balance. He was just about to say don’t be afraid, anyway, there is Lu Buwei to support you, but a shocking big hole shook Mo Dou to the ceiling, and his head was alive. Smashed a big bag.

Mo Dou covered his head, and continued with tears in his eyes: "My lord, do you still remember Lu Buwei? It's... hey!"

Another shocking crater, this time Mo Dou directly bit his tongue.

……

He wants to get out of the car!He wants to go home!

Ying Zheng suppressed his laughter, and finally stopped Mo Dou kindly: "There is no need for Dou to talk anymore, Zheng understands."

Now that Ying Zheng had said this, Mo Dou didn't bother to say more, wiped off his normal saline, and looked at the scenery along the way with peace of mind, although it was very barren.

The territory of the later state of Qin included most of Shaanxi, southwest of Shanxi, west of Henan, southeast of Gansu, and even a part of Sichuan. In terms of land area, Qin State can definitely be called the boss, but with so much land, the population is only more than 80 million.

What is the concept of 300 million?Beijing has a population of 2000 million, which is only 15% of the population.

Even after Qin unified the six countries, the national population was less than 3000 million. According to historical records, the ratio of Qin's population to the army during the Warring States period once reached 5:1, which means that the army had a full 60.

There are 60 people, all of whom are young and middle-aged, but they still serve as soldiers in an era when productivity is extremely backward... How chaotic this world must be.

Ying Zheng, who also didn't know what he was doing, was even more bored than the ink fountain who was looking at the scenery, so he took out the Rubik's Cube given to him by the ink fountain and tried hard to turn it, but he couldn't solve it no matter how hard he turned it, Ying Zheng could only turn his attention to Mo Dou's body.

"What is Doo thinking?"

Ying Zheng blinked innocently, pretending that he didn't reassure Mo Dou just now...

But Mo Dou, who was thinking about state affairs, didn't notice this, he replied casually: "I'm thinking about the number of people."

"Number?"

"Look, son, we haven't encountered any people at all along the way. The number of people is really too small."

Ying Zheng frowned: "Didn't we meet a few villages?"

"That adds up to only 1000 people."

"Isn't 1000 people enough?"

"Is 1000 people a lot?"

The two stared at each other, shocked by each other's thoughts.

In Mo Dou's eyes, this population is really very small. With 80 square kilometers of land and a population of more than 300 million, there is only one person in about 300 hectares!This is not sparsely populated, this is almost extinct, right? !

Of course, it is not as exaggerated as the extinction of human beings, but this figure is still shocking to Mo Dou.

Besides, 1000 people are really not many, and 1000 people is the amount of a primary and secondary school. In this era, even if they are gathered together, what can they do?In fact, he did not need to gather 30 people to build the Great Wall. It was not a formal construction, but just connecting the original Great Walls of various countries.

Mo Dou rubbed his head, and really wanted to tell himself that he was wrong and couldn't look at ancient problems from the perspective of a modern person, but after thinking about it, he still felt very strange, and felt like asking a few more questions.

"Since you think 1000 people is a lot, what about 1 people?"

"It's also a huge number."

"What if one thousand is compared to ten thousand?"

Ying Zheng frowned: "Aren't the two similar?"

Mo Dou was taken aback by Ying Zheng's impressive mathematical ability, and his voice became sharp: "Almost?!"

It was the first time Ying Zheng saw Mo Dou so excited, he was a little confused: "Isn't it?"

It is indeed similar, but this is from the perspective of modern times with a population of billions, but you, a person with a total population of only 3000 million in ancient times, thinks that it is very problematic, right? !

Mo Dou took a deep breath and felt that this matter was very serious. He needed to discuss it with Ying Zheng, and then he realized that he really overestimated the mathematics of this era.

Modern people know that the bigger the number, the bigger the gap between zeros, just like folding a piece of paper 26 times, it can be folded into the height of Mount Everest.

But this is an era when 0 didn't even appear, and the coins used to exchange transactions are not so popular, more people still barter, people basically don't use mathematics, so in their eyes , the difference between one and ten is not much different from the difference between a thousand and ten thousand.

Of course, not everyone is like this, at least businessmen can still figure things out; rulers need to be in charge of a country, and they also have certain mathematical skills, but don't expect them to be able to calculate the ratio of men to women, birth rate, death rate, etc. After all, the census will not be conducted until the future Qin Shihuang.

In fact, most countries may not know how many people they have. They only have a very vague concept. Let the people plant seedlings in spring, wait until autumn to harvest, and recruit civilian husbands or troops in winter. I feel that the collection of people is enough. I probably understand that there are not many people in my country...

Why do you say Shang Yang is great?They have done things like household registration in a serious way, and they have a very long-term vision.

Mo Dou covered his face. He understands why Taoists advocate inaction and governance. It is true that governing the country is better than no governance. It is better to let the people develop in peace and stability. It is better than you as a monarch...

King Liang Hui in "The Widow in the Country" in "Mencius" is a typical representative of tossing around. You said that you transferred all the refugees to Hedong, so why did you transport the grain to the disaster-prone Henan?What do you let the people in Hedong eat? !

When I first learned this text, Mo Dou was already unable to complain. This logic is as touching as the study of letting the freshman sweep the snow this year and the sophomore next year.

But no matter what, Mo Dou would never allow Ying Zheng to make such a mistake, so he silently put basic mathematics on the agenda.

I don't want to learn any trigonometric functions, but please understand that although there is only a difference between one thousand and ten thousand, just like one and ten, the difference between them is completely different!
