History is so mysterious, ancient things are national treasures today, and they are priceless; Today's things are in ancient times, they are miracles, and they are to be worshipped, and between this back and forth, across thousands of years of time and space, no matter what it is, it has been given a thousand years of time value, so the four operations will also rise, and they will naturally be valuable......

Only then did Suning react, and almost forgot, well, the level of mathematics in the Tang Dynasty may be the level of elementary school to junior high school in later generations! Especially for basic operations, there are no four rules of operation and formulas at all, and they are still stuck in a way of adding up to the top, and they have not jumped out of the original basic field of knotted rope counting, how many years, except for a few amazing people, such as Qin Jiushao, such as Zu Chongzhi, most people still dare not jump out of that crucial step.

Be a stick in the mud! Treasure yourself!

This shortcoming must be corrected! Otherwise, so many excellent skills will be lost! What's the best way to preserve your skills? Get it out! Of course, it is not passed on to other ethnic groups, but only to the people of the Tang Dynasty, like some small Japanese envoy to the Tang Dynasty or something, well, all put it in the Hongwen Museum, let an old Confucian like Kong Yingda teach them the Four Books and the Five Classics, and pour a belly of Confucian knowledge back to preach and teach and solve doubts! Want steel smelting jishu? Want a weapon jishu? Miss your sister!

"It's just a very simple four-rule operation, the so-called addition, subtraction, multiplication and division, arithmetic is so simple, is it difficult?" Suning pretended to be puzzled and asked, Li Chengqian rolled his eyes, what kind of person is this! Such an unpredictable skill, shouldn't it be taken seriously? If this stunt is mastered, how much easier will it be for the dizzy officials of the household department who hold calculations every day? Do you still need to prepare for emergency rescue as soon as you arrive at the tax season?

However, it seems that people in this era respect private property, and they seem to take the master's stunts and family heirloom stunts very seriously, even the emperor, and it seems that he has no right to ask others to offer the stunts, otherwise, it is not respecting the ancestors, not respecting the teacher, not being filial, that is a big crime, and it is to be scolded, so Li Chengqian is embarrassed to say it, but where can Suning not see Li Chengqian's thoughts?

"You want to learn?" Suning asked lightly, Li Chengqian was startled, and quickly shook his head: "No, no, no, Sanming, this is your master's skill, and it can't be passed on, if I learn it, isn't it disrespecting the teacher?" Never! Never! ”

Suning looked at Li Chengqian's contradictory appearance of wanting to learn to death but not letting go of his mouth at all, and he was very unhappy: "Who told you that my master's stunt is not passed on?" My master and I are the only two of them, and there are not so many bad rules! If you want to learn, you can say, my master is not an antique, he said, if you want to keep a skill all the time, the most haode method will be passed on, one person is not insured, a hundred people are not safe, ten thousand people should always do, right?

These four calculations are not gold and silver or anything like that, they are just some knowledge, what if I don't pass them on and hold them in my stomach? Am I that kind of person? I have always been upright, kind, pure, and majestic! Never hide your selfishness, especially in the face of your own brothers! Second goods, Xiaozhen, Bo Yao, do you want to learn? If you want to learn, just tell me! It's all my own brothers! I also thought that if I had a reputation in the future, I would accept disciples from all over the world to impart knowledge, and now is the right time to practice with you! ”

Li Chengqian said with a look of surprise: "Sanming, you, you, you still want to start a sect?" "Since hearing everything Suning said in the morning, Li Chengqian is very yearning for the knowledge that Suning has learned, very eager, and has decided that even if he is a teacher, he must learn these knowledge, and now Suning doesn't care about the spread of his master's skills, and is also preparing to start a sect? Recruit disciples from all over the world?

Eldest Sun Chong also looked incredulous: "The Venerable Master is so enlightened? This, that's not quite right, right? ”

Li Zhen and Li Boyao, the two Xiao Lis, opened their starry eyes, and their crazy curiosity made Suning unable to say anything else......

"I've said it all, there aren't so many rules, I'll teach you if you want to learn! It's simple! Everyone in Datang will know these things in the future, including literacy, writing, and reading, and everyone in Datang will be able to know these things in the future! My greatest wish is that there are no illiterate people in Datang! Everyone is literate! "Suning said his great goal, the great goal of eradicating illiteracy!

"Everybody is literate?" The four little tyrants shouted loudly in unison......

Suning looked at the four of them: "What's wrong?" "Although this thing is very difficult to do, it is not that no country has done it, it is difficult to popularize education, it is not impossible to do it, fifty years, one hundred years, as long as you have time and power, even if it is just to make a prototype, as long as you find a suitable heir, this cause will definitely be done!

The four of them looked at each other, their eyes were shocked and incredulous, but they shook their heads neatly and reserved their opinions, because in their opinion, in this era when books are hard to find, if you want to do such a thing as national literacy, it is not a question of whether it is difficult or not, but a question of whether you can become a god, and people's worship of culture is destined to become a god......

Suning didn't care about this, took out a pen and paper and began to explain the basic operations of addition, subtraction, multiplication and division, by the way, the Arabic numerals were also said, and the conversion of Chinese characters is so simple, one to zero, Chinese characters have long been there, a conversion, it is not difficult, and then it is a simple four operations, this is not a moment and a half to explain clearly, how to learn in elementary school Suning almost forgotten, so just said a rough idea, and then predicted what the future would be, and listened to the next decomposition......

After feeding the four little tyrants, one person hit a big bag and drove away, Suning began to work on the future of Jihua, by the way, the two thousand acres of fiefdom given by Li Erbixia have not been taken care of, these fiefs need to be taken care of, and then look for a few more Haode fields, find a few reliable honest people, take advantage of the arrival of the spring ploughing season, and start trial planting a series of high-yield crops such as hybrid rice, potatoes, and corn, to see if time and space will have an impact on these crops.

This package of hybrid rice seeds is very important to Datang, Suning understands, at this time, the grain planted in Datang is basically wheat, as well as some other miscellaneous crops with very low yields, as for rice, this plant can only be planted in the Jiangnan water town and the place near the tropics that is still regarded as a wild land because of the primitiveness of the variety, double cropping rice has been recorded as early as the Han Dynasty, but it has not been introduced and planted on a large scale, almost because rice seeds are still relatively primitive, It cannot adapt to the colder and water-scarce environment in the north.

Later, more than 1,000 years of planting process have also proved that rice is a more fragile food species, and the production environment is relatively restrictive, which prompted Mr. Yuan Longping to preside over the hybrid rice jihua, after a long time of hard work, hybrid rice this super food can be produced, not only stronger than the current conventional rice, but also the yield per mu will be much higher.

According to the information consulted by Suning, the scientific research team led by Yuan Longping successfully overcame the two major difficulties of super hybrid rice yield of 700 kg and 800 kg per mu in 1999 and 2005, so that China's hybrid rice ultra-high yield research maintained the leading position of Shijie, and this bag of seeds was purchased by Suning's father and mother three months ago, and it was 2013!

Counting the gap between the area of the Tang Dynasty and the fertilizer and planting methods, there should also be five or six hundred kilograms, that is, the yield per mu is more than 1,000 catties, and one stone in the Tang Dynasty is converted into the current weights and measures is almost fifty-nine kilograms, and the main grain crops planted in the Tang Dynasty The yield per mu of wheat is only one stone, and the most Haode Gyeonggi fertile land is only about one stone and a half.

Chang'an is located in the north, although it has the title of thousands of miles of fertile land in the country of abundance, but the problem of climate still exists, whether this hybrid rice can be successfully planted is also a problem, but now the south of Datang is still a barren, want to develop into a thousand years after the land of fish and rice, it is really not easy, with the current ability of Datang and Li Erbixia's temperament, if you immediately start to develop Jihua in the south of the Yangtze River, Datang can die in almost ten years......

Roads, climate, diseases, manpower, material resources, resources, official appointments, pig-like teammates, etc., etc., all need to be considered, the so-called if you want to get rich first to build roads, to develop Jiangnan first, you have to solve the problem of roads first, cement? It's not very difficult to get it, and the things that come out of the sand are not expensive, and you can use local materials, but laying a cement road is a very troublesome thing.

There are so many things that need to be considered if you want to transform Datang, and there are definitely more than just a few things......

But no matter what, even if only two stones and three stones can be grown, and it will be two or three times the grain growth in the whole Datang, what will Li Erbixia be happy about? This is not counting potatoes and corn, the absolute high yield of potatoes, although it is more suitable for cooking than grain, as for corn, there is still no rice and wheat suitable for food, but they are all the same high yield, these three killer features down, Datang is still afraid that there will be no food to eat?

Oh! The locust plague is also a problem, by the way, the history books seem to say that who went deep into the locust origin to solve the locust plague, and since then it seems that there has never been a large-scale locust plague in China, how is this done? And what's more serious is that locust plagues are often accompanied by droughts, which is a two-pronged approach, if the locust plague that covers the sky and the sun appears, rice, potatoes, and corn can't bear it!

Suning still took out the magic machine on Baidu, and began to study how to exterminate locusts in depth, the history books record that the nearest relatively large locust plague is a locust plague in the second year of Zhenguan, and a locust plague of a considerable scale appeared in an average of seven or eight years during the Tang Dynasty, although there is no record, it is normal, who does not understand the penmanship of the Spring and Autumn Period? Can't discredit the prosperous world! There is no need to record locust plagues in several states......

After checking the locust matter, Suning began to check the planting methods and precautions of hybrid rice, but unexpectedly found that hybrid rice cannot be left with seeds, it can only be planted once and eaten all, and then it is necessary to continue to buy seeds! Suning was devastated, although he had planted the land before, but he had never considered this kind of problem, the second generation of hybrid rice planted as rice seeds would produce trait separation, and then it would cause the tragedy of a sharp decline in yield!

If hybrid rice is tried to grow, only the first year can produce high yields, and the second generation is a tragedy! If you don't know this, after the first generation is planted, you will be able to plant it to Li Erbixia, and Li Erbixia will be overjoyed and ordered to plant extensively, but the tragedy of the second generation will occur and the yield plummets, and Li Erbixia will not stew himself immediately under the joy and sorrow?

Luckily, I have a little more heart, damn it, how is this good? What a cheat! It seems that nothing can violate the laws of nature, and if you get the yield, you have to pay the price, which is a big hidden danger......

Suning took out his backpack and continued to flip through, in addition to the big bag of hybrid rice seeds, Suning also found a bag of rice seeds, took a look, Suning was overjoyed, it seems that he was too nervous when he turned over the backpack, and he didn't see it clearly, in addition to this bag of hybrid rice seeds, there is also a bag of japonica rice seeds, conventional rice, not hybrid, rice suitable for planting in North China, are temperate regions, should also be planted here in Chang'an, and the yield of this japonica rice should also be relatively high, although I don't know how much, But it was always much higher than the wheat it is now.

As for hybrid rice, Suning has other ideas...... After all, it is a modified seed after a thousand years, if something can be discovered, or simply cultivated to the third and fourth generations, even if the traits are separated and the yield is extremely low, will there be some mutations and surprises? Can you keep the seeds and continue planting? After millennia of development and adaptation, the vitality and yield of these seeds after production will inevitably be stronger than the current seeds.

That night, Suning instructed the servants to go to the Confucian Mansion to take leave, saying that they were infected with the wind and cold, and their hands were swollen, so they asked for three days of leave, hoping that Mr. Kong would approve it; Kong Yingda smiled slightly, disappreciated, and agreed.

So Suning had three precious days to go to his fiefdom for field investigations, and to carry out the first batch of trial planting, so early the next morning, Suning and Wang said hello, and took Niu Geng and the four major soldiers, as the county of Sanyuan out of Chang'an, all the way to Sanyuan County, which opened the prelude to the agricultural revolution.

Speaking of the four pro-soldiers, it is also quite interesting, one is called Zhang San, one is called Zhao Si, one is called Wang Ermeng, and the other is called Ma Xiaoliu, it is simply weak, and there must be a little momentum by his side, if there is no momentum at all, is this kind of name laughing and generous soon after it is called? So Suning suddenly had a whim, and gave each of the four of them a name that shocked the past and the present - Zhang Long, Zhao Hu, Wang Dynasty, and Ma Han!

When the time came to hoe the strong and help the weak, as soon as he appeared, he shouted: "Zhang Long Zhao Hu Dynasty Mahan!" "What a momentum! It's just that Suning is not a little worse than Bao Zheng's black charcoal......
