All the feelings of compassion and repression will be smoothed out with the long road, and will be replaced by the long boredom and boredom.

In the yellow sand, the carriage convoy walked on the sparsely populated sandy ground.

This geographical situation is not a desert, but somewhat similar to the Gobi, and the land is mainly composed of loess and yellow sand. When the wind blows, it is extremely prone to windy and sandy weather, but in fact, it is not a real desert.

It is said that 70 percent of the vast land is desertified. But dig 50 meters down, and it's all loess. Dig further down and you'll find an underground river. There is no shortage of water.

"Ah, it's so boring, how long will it take to get to Huangpu County."

Liu Quan roared shirtless, with a veil wrapped around his head.

Li Zhen is also a little embarrassed, he has been on the road for more than a day, and it is really a long road. On this carriage, you can't read books, and you can't learn to study. Because of the bumps, everyone actually has some motion sickness.

Teacher Wang, who rushed to the exam with the team, laughed and said, "You two, you really haven't traveled a long distance." When I was studying here and there a few decades ago, I even walked alone from Hangcheng County across Kyushu to Xizhou. ”

Another teacher Li took a sip of water and said lightly, "What's the hurry?" Now that we are in Tongxiang County, there is probably more than an hour to go before we can enter Jiahe County. When we arrive in Jiahe County, it is not far from Huangpu County, and we can stay in Jiahe County for a day and have a good rest. You two kids haven't been out of the house yet, have you? Let me tell you, Jiahe County is much more prosperous than Hangcheng County. ”

Li Zhen asked curiously: "How prosperous is it?" ”

"Jiahe County, seventy percent of the land area in the city is a loess oasis. It's not far from our Hangcheng County, but Hangcheng County is a sandy environment. Jiahe County is a loess surface. There were a lot of merchants in the past. In addition, Jiahe County is also the only way to Huangpu County, and merchants from all over the country will gather in Jiahe County, which is extremely prosperous. In the entire southeast state, only Jiahe County can be compared with Huangpu County. ”

Li Zhen asked again: "How many people is there in Jiahe County?" ”

"It is rumored that Jiahe County has a population of more than one million."

Liu Quan's eyes widened: "Million!" Legend has it that Huangpu County has a population of only 1.5 million, which can be called a giant city in Southeast Prefecture. The population of this Jiahe County can also exceed one million? ”

Li Zhen asked again: "What is the GDP of Jiahe County in a year?" What is the data of the differentiation of the old and the young in China? What is the ratio of men to women? Has there been a per capita property count? ”

“……”

The whole team was full of black lines.

Teacher Wang wanted to laugh, but when he saw that Li Zhen didn't seem to be joking, he livened up the atmosphere, and saw that Li Zhen had already recorded a lot of dense things in a small book. It's all about the human geography along the way, and my heart is immediately full of emotion. This is what a scholar!

Teacher Wang Zhengse said: "I can't give you a rough idea of these rigorous data. If you're interested in something from Golden Harvest County, we're still an hour away, and when the time comes, wouldn't it make more sense for you to investigate it yourself? ”

Li Zhen nodded and stopped talking.

Liu Quan laughed and said, "Are you nervous?" How much do you care about people's gross domestic product (GDP), and it has a relationship with you......"

Before the words fell, Teacher Li interrupted: "Student Liu, what you said is not right. You are students, you are the talents of the future empire, and you are going to serve the empire. Know more things, know more things, if one day the official is added, it will be the benefit of the four seas. As the old saying goes, this is the truth of reading 10,000 books and traveling 10,000 miles. ”

Liu Quan pursed his lips and said unconvinced: "It's useless to know these things, what is the gross domestic product, that's someone's business." Even if you know, it's meaningless, can you still analyze it? ”

Teacher Wang laughed and said: "There is nothing difficult in the world, but I am afraid of people with hearts." Lee is really a mathematical genius, and he can analyze extremely useful things from some numbers that ordinary people can't understand. It's a science, and if you have the opportunity to go to university, you'll learn a variant of mathematics, 'statistics'. ”

Liu Quan shrugged his shoulders and poked his fingers at Li Zhen, who was in a daze: "Hey, tell me what 'statistics' is." Don't hide it from me, you'll know it. ”

Li Zhen smiled, summed up the language and said: "Its practical sentence summarizes statistics, that is: through sorting, searching, describing, analyzing data and other means, to achieve the essence of the target of an object, predict the future direction of the speculated target, the feasibility of diversified development, and even predict the percentage of the target's life and death, a discipline covering social science, natural science, prediction, etc., which is extremely comprehensive and complex. ”

'Ah......h

A convoy of people collectively petrified and looked at Li Zhen dumbfounded.

Liu Quan was stupid and buckled his head: "What did you just say?" You say slow down, I didn't hear clearly, my brain is buzzing at this moment, it's messy. ”

Li Zhen repeated it again with a smile and wrote it down for him, so that he could understand it more intuitively and literally.

After Liu Quan finished reading it, his heart was about to jump out of his mouth, and he said in horror: "How can it be so magical?" Do you know the specific data of a city, and use statistics to calculate it? Can you calculate the future business direction of the city, which direction of development has a high success rate, and even when the city will collapse? ”

Li Zhen smiled and said nothing.

Teacher Wang said with a straight face: "That's just the skin." Real statistics is more complicated than you imagined. ”

Several teachers glanced at Li Zhen deeply, feeling a little unbelievable.

If memory serves...... No one in public high schools teaches statistics at all, seeing that Li Zhen knows more than his own teachers, how does he know?

Liu Quan also looked at Li Zhen with complicated eyes, and sighed softly, no one knew what this sigh meant.

Li Zhen was a little embarrassed when he saw that everyone was silent, and sneered: "Actually, it's not as difficult as you imagined." ”

"Isn't it difficult?"

Teacher Li hurriedly came over.

Li Zhen shook his head: "It's not difficult, it's like doing a 'single-digit X equation'." When we know the known data of a thing and get the conditions, it is not difficult to find the unknown number X. It's just that the means of calculating it are more complex and require more formulas. ”

The teachers shook their heads with wry smiles and never spoke again.

Liu Quan squinted at Li Zhen, and there was disdain in his eyes.

Rub, I hate you pretending to be bland like this. And to say it seriously...... It's not hard.

Alas, this is probably a peerless powerhouse.

Legend has it that there is such a peerless powerhouse, who sighs before every exam, saying that he didn't review yesterday. After the results came out, it turned out to be the first place in the perfect score, and I said to other students, I didn't expect this question to be so simple......

In Liu Quan's eyes, Li Zhen is now this kind of peerless powerhouse who is extremely underbeaten.

It's so complicated, it sounds like a big head, and it's not difficult for him to end with a sentence.

Liu Quan didn't want to talk to Li Zhen anymore, so he took out a square box from his personal backpack as if offering a treasure, and held it in his hand as if it were a treasure.

Li Zhen glanced at it and said in surprise: "You even have a radio!" ”

Liu Quan finally saw Li Zhen with a surprised look, and couldn't help but be proud: "Hmph, this is what my father bought for me." Awesome, right? This is a 'semiconductor radio' that a great scholar of the empire reconstructed and invented according to the description in ancient books. It's not been a long time since it was invented, and now it's 100,000 yuan a piece. Expensive or not. ”

Li Zhen gasped: "100,000 coins!" ”

"yes, I didn't brag to you. In the entire Hangcheng County, there are only ten semiconductor radios. There are two in my family, and there are a few other wealthy businessmen. There is also a county lord who only has Hangcheng County, which is used to receive the latest instructions from the state, as well as big news events. In the whole of Hangcheng County, there are only ten, and I only have one! ”

Liu Quan was extremely pretentious, and began to pull out the one-meter-and-five-long antenna, and then fiddled with it. After a while, there was a noisy voice of people talking and broadcasting.

A group of teachers also came around, scrambling to watch, and they were amazed.

"It's amazing."

"What kind of principle is this?"

"How can a square box receive an audio signal far away?"

"I've heard that the senior officials of the Southeast State have plans to lay some roads to receive audio, so that the signal will cover the entire Southeast State. It seems to be covered, and before it reaches Jiahe County, you can hear the sound. ”

“……”

Liu Quan looked at everyone triumphantly and showed off: "You don't understand. This is because we are approaching Jiahe County, so we can hear the sound, and there is a radio station in Jiahe County. We don't have it in Hangcheng County, and we generally can't receive the signal. The radio of the county lord was given by the Kyushu Imperial Court, and it was the most advanced and dedicated. It seems that people's radios can receive signals from Nakashu. ”

Along the way, everyone magically surrounded Liu Quan, and Li Zhen was also quite curious, listening to the voices of the people speaking in the gradually clear inside.

Li Zhen naturally knows the semiconductor radio, and he also knows the principle. These are the basics of high school, and Zhang Zhi taught him this course a long time ago. But he had never seen it.

Liu Quan said impatiently: "It's all light, don't break it for me." Okay, okay, let's get here today, and listen to it tomorrow. Just listen to it for 20 minutes a day, this battery is expensive. Only Zhongzhou sells it. ”

As he spoke, Liu Quan put away the semiconductors with pride on his face, and looked at Li Zhen, and his eyes became even more colorful.

Hmph, I've finally compared him a little bit, and I've finally been able to get a little bit of attention from this guy.

"Ahh

Liu Quangang installed the radio, but suddenly heard a terrible scream from the front of the horse convoy.

"What's wrong!"

The crowd gathered in a carriage was shocked. They all ran out to take a look.

Li Zhen jumped out of the carriage and stepped on the ground to look forward. But when I saw the hired groom standing at the front, his legs trembled, and the whole person was already frightened......

At the forefront, in a valley, forty or fifty bloodied corpses lay on the ground, and their deaths were miserable.

"This ...... This ......"

The crowd was in a state of disarray, and their hearts became heavy and frightened.

Li Zhen kept a trace of calm in fear, and looked at the corpses carefully, but saw that seven or eight of the corpses were weak-crowned teenagers. There was a lot of luggage scattered along the way, and all the daily necessities such as clothes were turned out.

There were carriages, but only carriages remained, and the horses were gone. Everyone's pockets were turned out.

Looking at the topography of this valley, there are stone mountains on the left and right, and only a narrow passage in the middle is about two or three kilometers long. There is no road in all directions.

"It's ...... What's going on. ”

Liu Quan was already paralyzed to the ground in fright, where had he seen a corpse?

Li Zhen became short of breath, and hurriedly said, "Hurry up, keep quiet, everyone must not make a noise." Over here...... There are horse thieves! ”

"Ahh Horse thief! ”

"What a bold man, this is the main road to Jiahe County, and there are horse thieves here."

"I know, this is Swallow Rock!"

"Swallow Rock?"

"I always heard that in recent years, when rushing to take the exam, there will always be some students who have disappeared near Yanziji, and they can't see anyone alive or dead. Some people say that it is a horse thief, a candidate who specializes in robbing the exam, and a merchant who goes to Huangpu County to do business. I didn't expect it to be true......"

Swallow Rock!

Li Zhen hurriedly jumped into the carriage and shouted in a deep voice: "Go!" Come on! ”
