The prefect of Yan'an said: "Xincun Bookstore is indeed more than just a bookstore, it has become a place for people from all walks of life to communicate. ”

Hong Chengchou was a little stunned when he heard it, but he didn't care, he had arrived at the door, and he would understand when he went in and took a look.

Walked in with your feet raised!

As soon as I entered the first yard, I smelled a strange stench, like the smell of "feces".

How can there be such a smell in a bookstore?

Hong Chengchou frowned, very dissatisfied, turned his head to look at the taste, and immediately saw a group of scholars, who were surrounding a flower garden, studying something.

One of the scholars was shaking his head and said, "Look? I just said, the effect of chemical fertilizer is better than manure, don't you believe it, now you see it? The crops that have been watered with manure will grow ordinary. And the crops that have been watered with chemical fertilizer here are growing more gratifying, which is called science! ”

As he spoke, the scholar took out a book and flipped through it in a loud voice: "The book says that the things that crops need are very complicated, the acidity and alkalinity of the soil, the iron and sulfur in the fertilizer, and various chemical elements must be corresponding. If you simply pour manure on crops like this, you can't understand some of the chemical ingredients, it's too unscientific, and it can't be dropped. And on my side, the fertilizer is carefully used to every pound and every tael, how can it be better than you? ”

Another scholar next to him was obviously the losing side, with a bitter face: "Xiaosheng was born poor, and his family farmed on behalf of others, all of which used manure, but I didn't expect to carry such a big heel here today, just that, in the future, Xiaosheng will also obediently learn to use chemical fertilizer." ”

The scholars next to him coaxed: "Hahaha! Who told you not to even believe in the Book of Heaven? That is, Tianzun is generous, and he will not be held accountable, otherwise, if you question the Book of Heaven, you will be convicted of blasphemy. ”

As soon as they finished speaking, Gao Shan, the owner of the bookstore, jumped out and said with a smile: "This is not right, Tianzun is very supportive of this kind of questioning of Tianshu and using experiments to demonstrate Tianshu's behavior." It will never be considered blasphemous! Anyone can doubt the Book of Heaven from any angle, as long as you can prove that the Book of Heaven is wrong with examples, Tianzun will award you a grand prize. ”

The scholars laughed: "Tianzun is merciful! ”

Hong Chengchou was shocked, walked over, and said to the scholar holding the book: "This brother, can you lend the book in your hand to the official." ”

The scholar smiled: "Of course there is no problem. ”

He handed over the book in his hand......

Hong Chengchou picked it up and took a look: "Methods and Techniques for the Use of Chemical Fertilizers." ”

To be honest, he couldn't read the title of the book, but when he opened it and looked inside, he understood that it was a book that taught people how to fertilize crops, how many crops were drawn in it, and each crop was detailed how to use chemical fertilizer.

How to match it, what season to use it, the level of detail is simply outrageous.

It's as if there are a hundred old farmers teaching themselves how to farm.

Hong Chengchou didn't need to learn such knowledge, but he also admired the person who made this book, and couldn't help but sigh: "This is a good book for the benefit of the people, and it should be vigorously promoted." ”

The scholar said: "Of course it is being vigorously promoted, this book is very cheap, ten cents a copy, it is simply half bought and half given." ”

Hong Chengchou: "! ”

The scholar said: "However, ordinary farmers are illiterate, and they can't read this book when they buy it, which is the biggest problem. ”

The scholar who had lost for a while just now also got up from the ground: "Xiaosheng also has to go back to teach his parents to use chemical fertilizer, well, I have to buy a copy of this book." ”

Hong Chengchou felt as if he had learned something, and he had just entered the door of the bookstore, and he saw such a scene, and there was something else in it, which made him very excited.

Walking further inside, I saw a few scholars, arguing about something here.

As soon as he listened attentively, he heard a scholar say: "It turns out that the Francos we have been talking about is actually from two countries, one is called Spain and the other is called Portugal. ”

Another scholar said with a smile: "There is also the red-haired man in our mouth, the one called Holland, also known as the sea coachman, they run trade all over the world through big ships, and they are very powerful, we are far behind Europe in terms of maritime trade, we must be vigilant." ”

"Brother Zheng, your father seems to be in the silk business? Have you been running the Silk Road? ”

"Yes!" The man known as Brother Zheng said: "My caravan is only as far as Persia, and I am blind to the situation further west, but I didn't expect that there are so many countries and such a complicated political situation on the western side." Tut! ”

As he spoke, Brother Zheng took out a huge map and spread it on the table: "Look, this is the farthest place my caravan's caravan has reached, but further west, there is still a lot of vast place...... I really want to make all these people's money. ”

A group of scholars laughed together: "You Zheng family alone, you can't do it, don't think about it, hahaha!" We'll have to go up with a few of us. ”

Hong Chengchou was secretly shocked in his heart.

He also didn't know much about the Silk Road, so he skipped it.

Walking into the next courtyard, I saw two scholars, facing a sand table, falling into deep thought.

The sand table is made very large, and the mountains and rivers are lifelike.

Hong Chengchou glanced at it and actually recognized that this sand table was...... Topography near Shanhaiguan.

This is no small surprise!

A scholar picked up a villain and placed it on a mountain outside Shanhaiguan with a snap: "I set up an ambush here, what should Your Excellency do?" ”

The villain on the opposite side snorted and said, "It depends on what kind of soldiers you deploy." You don't have many flags to use, so you'll have to place an infantry squad here, but my artillery unit hasn't moved yet. ”

He picked up a miniature cannon and swung it at the foot of the mountain: "Boom, boom! All your ambush soldiers will be killed. ”

Hong Chengchou smiled dumbly: "On paper!" ”

While he was laughing at this, he saw a scholar grab a strange model, which seemed to be a chariot, but not like a carriage, like a square box made of iron.

The scholar slapped the square box on the back of the hillside with a "snap", and said with a smile: "You have been tricked, my armored cavalry regiment has been waiting here for a long time, and your artillery position has just been arranged, and my armored cavalry unit rushed out from behind the mountain and crushed your artillery position into powder." ”

Hong Chengchou jumped out of the ground: "Slow! You call this strange thing armored cavalry? Where the hell does it look like a cavalry? ”
