Chapter 42 Inventions of the Song Dynasty

In the Duobao Pavilion, several people sat around the wooden table.

Shopkeeper Li patted the dark brown wine urn and sighed: "The Song Dynasty was open-minded, prosperous in business, open-minded among the people, and did not regard craftsmen as a cheap industry, all kinds of inventions emerged in an endless stream, and the science and technology were leading the world. ”

Xiaoxiao came to be curious, held a small face, and asked playfully: "Grandpa, what did the Song Dynasty invent?" ”

"The Song Dynasty, if it weren't for bad luck and ran into Mongolia that swept across the Eurasian continent, it would have been a great dynasty."

Shopkeeper Li sighed lightly and said: "Among the four great inventions of China, the compass, movable type printing were all invented in the Song Dynasty, and there are cannons ······."

"What? The cannon was invented in the Song Dynasty? Yin Duobao exclaimed: "I always thought it was the Ming Dynasty, or a foreign devil, what kind of Franco's cannon, red-coated cannon or something." ”

"Surprised, what's there to make a fuss about, is it unusual for the ancestors to invent cannons?" The shopkeeper Li reprimanded angrily, and said: "There are detailed records in the history books that the cannon was invented in the Song Dynasty, in 1126, the Jin people besieged Bianjing, and Li Gang used a thunderbolt cannon to repel the Jin soldiers when defending the city.

And the basis of firearms, hand cannons, also appeared at that time. ”

He Shen said softly on the side: "This old man has a good memory, master, there is indeed such a record in history, and it is also clearly pointed out in the "Siku Quanshu" compiled by the slave. ”

Su Ren nodded to show that he understood, after the little milk cat finished drinking, his wet nose sniffed, accurately found Su Ren's location, gently rubbed his ankle with his little head, and raised the cat's face to "meow" and scream.

Bending down to hold it in his arms, the little milk cat was full of food and drink, curled up in a ball and closed his eyes, and snored comfortably.

At this moment, the phone rang, and the shopkeeper Li answered the phone, his surprised look flashed, "En'en, ah" replied a few words, and then touched his little head dotingly, glanced at the wine urn on the table, showed a regretful look, and left anxiously in disappointment.

A few people got up and sent Shopkeeper Li to the door, and on the way back, the little Lala Suren's clothes and blood-red eyes were full of expectation and asked: "Uncle, the old man is gone, do you know what else the Song Dynasty invented?" ”

Su Ren sat back in place, stroked the soft fur of the little milk cat, and pondered: "I also invented the technology of drilling deep wells, and Zhuo Tube Well is a salt well with an upright thick bamboo tube to absorb brine," digging the ground and planting bamboo, and Zhuo Tube Well was invented in the Qingli period of the Northern Song Dynasty (Gongyuan 1041 ~ 1048), more than 800 years earlier than the West. Its caliber is only the size of a bamboo tube, but it can drill wells as deep as dozens of zhang, and is known as "the fifth great invention in ancient China" and "the father of oil drilling in the world".

The scientific and technological circles have a very vivid analogy for Zhuo Tuojing: "Without Zhuo Tuojing, there would be no Gulf War."

Regardless of whether Xiaoxiao can understand it or not, Su Ren said a paragraph as if he was memorizing a text, this paragraph was the key exam content at the beginning, and he memorized it by rote many times, so Su Ren remembered it very clearly.

"Anything else? Anything else? "Xiaoxiao is beside him.

Su Ren was embarrassed, and there was nothing he could do in the face of the pestering poor little girl, so he couldn't help but set his eyes on the know-it-all and Shen.

He Shen lived up to expectations, and immediately bowed and said: "Master, the Song Dynasty also created an abacus. ”

Su Ren nodded and spit out the word "abacus" directly.

"I know that." Xiaoxiao clapped his hands and said in a jumping voice: "I still learned this, add five to ten plus break five into ten."

One-one-up-down, five-to-four-one, nine-in-one-two-two-up, two-two-down, five-to-three-two, eight-in-one·······"

A series of digital formulas made Su Ren dizzy, and Yin Duobao was even more unbearable on the side, his eyes were straight, and a trace of saliva flowed from the corner of his mouth, looking like a demented child.

"Uncle, did I carry it right?" Xiaoxiao was full of anticipation and eager to be praised, Su Ren was very authentic, and satisfied the other party lightly, and immediately raised his thumbs and gave five likes.

"Uncle, is there any invention in the Song Dynasty?" Xiao asked.

Is there an invention or not, how do I know, Su Ren scratched the itchy bandage on his forehead, half a sound, and said with some uncertainty: "There should still be banknotes." ”

Xiao Xiao was surprised: "So early, did the Song Dynasty invent paper money?" ”

Su Ren nodded, and said thoughtfully: "Jiaozi, called Jiaozi in the Song Dynasty, remote access and withdrawal, common throughout the country, similar to the current bank, six hundred years earlier than the earliest Swiss bank in Europe. ”

Xiaoxiao asked, "Is there anything else?" ”

He Shen stalled his hands, saying that he couldn't help him, the Qing Dynasty, Shinong industry and commerce, craftsmen were lowly industries, and strange and clever tricks were not welcomed, and how could the big officials pay attention to these things.

Su Ren leaned back in his chair weakly, thinking about it, the Song Dynasty invented a lot and learned it in college, but these unpopular knowledge are easy to forget in his mind.

Yin Duobao quietly handed over a mobile phone, the screen was the checked information, Su Ren was inexplicably grateful, and hurriedly took the mobile phone to Xiaoxiao.

Seeing this, Yin Duobao covered his big round face in pain, and looked at Su Ren with small eyes and complained.

Xiaoxiao took a look at it and read to the screen: "Watertight bulkhead, the warships of the Song Dynasty (960~1279) have generally adopted watertight bulkhead technology to improve unsinkability. It can protect the ship from sinking due to flooding, and it is still an important structural form in ship design. The discovery of Nanhai No. 1 proves that China was the first country to invent this technology.

Finally, the canal lock in the form of a double lock, invented in 984, the Huainan transshipment made Qiao Weiyue responsible for the management of the Huai River, and created the Erdoumen, which is a canal lock in the form of a double lock, thus improving the river transport capacity. After influencing the world. ”

"It turns out that the Song Dynasty invented so many things." After Xiaoxiao finished speaking, Mei Zizi put the mobile phone in her pocket, and stretched out her pink little hand to pat it on the pocket a few times, showing a smug expression to Yin Duobao.

"Ah, seven generations of my Big Apple!" Yin Duobao was greatly remorseful, and hurriedly begged for mercy: "Good niece, good niece, this is my newly bought Big Apple ······." ”

"Master Su."

The middle-aged man rubbed his eyebrows and walked from the back room to the hall with a little tiredness.

"The place has been found, it's a huge school."

Su Ren sat up straight and asked, "Where is it?" ”

The middle-aged man glanced at Xiaoxiao, who was playing with Yin Duobao, and said with relief: "The prairie, Sara Town, the town is not big, with a population of more than 100,000, but the school accounts for half of the area of the town, because there are still nomadic customs, and the herdsmen within a radius of three hundred miles will board their children in the school."

The name of the school is Yucai High School, and the students at the three levels of elementary, middle and high school are all in the same school, and the boarding capacity is about 20,000, while the number of children enrolled in the primary school is about 3,000. ”

Su Ren asked, "Is there only one school in a district?" ”

The middle-aged man nodded: "There is a developed nomadic industry, there are many ethnic minorities, and due to the environment, there is indeed only this school." ”

Su Ren stood up, threw the little milk cat to his shoulder, ignored its big tail wrapped around his neck, walked back and forth a few times, and said in a condensed voice: "Enough, if the situation is true, there are many vitality suppression, and Xiaoxiao will be able to sleep peacefully." ”
