Agrarian civilization is indeed a disadvantage in the face of nomadic civilization, in the case of pure war.

Weakness, though?

Liu Rui asked Han Jiang rhetorically: "Han Jiang, does Wu Anjun have weaknesses?" ”

Han Jiang replied: "On the battlefield, he didn't. ”

Liu Rui asked again: "Wu Anjun can be defeated by a new army with new equipment. ”

"This!" Han Jiang was a little hesitant about his own judgment, but he still said: "After all, it is human beings who go to the battlefield to fight, and it is also human beings who use weapons. ”

"That's right." Liu Rui didn't refute Han Jiang's words, but said: "Not to mention, there is no one in this world who does not have weaknesses, even if he doesn't." Stronger than him, twice as strong as not enough for five times. ”

Liu Guo shook his head: "No, no, he is strong, he is strong, we can still overcome rigidity with softness and use strength." What's more, we are stronger. It's just that we lack horses. If this problem cannot be solved, it can only be kept, and if it is only guarded, there will always be a day when it cannot be kept, so the horse farm must get a piece at any cost. ”

Lack of horses.

Liu Rui and Han Jiang both had headaches in this matter, and it was not an ordinary headache, it was a very, very headache.

The Great Song Dynasty lacked horses, and it was lacking since 200 years ago.

Now it's even more scarce.

Han Jiang and Liu Rui touched their wine glasses and drank the wine in the glass together.

This sip of wine, depressed!

Liu Rui opened the topic: "By the way, what else can the pressure cooker do?" ”

Han Jiang said: "It's my fault. ”

Blame you!

It's interesting.

Han Jiang said: "I used to get a little cement to build a house, and my eldest lady said that cement can save the Great Song Dynasty." ”

Liu Ruixin said: This is good, but it is impossible to save the Great Song Dynasty.

The biggest role of cement is to build a strong fortress, and it is really useful. But the Great Song Dynasty is no longer something that a few fortresses can save.

Han Jiang said again: "Later, I told her, Danfei. ”

Liu Rui asked, "What is Danfei?" ”

"There are three types of dandan, potassium, phosphorus, and nitrogen."

"Natural phosphate fertilizers such as sea bird droppings, fish bone meal, etc., are what I say a lot of people say can be used to synthesize phosphate fertilizers, and at the same time, red phosphorus can be produced."

Liu Rui answered: "I know red phosphorus, a good thing to make matches." I heard that it is being used to make burn off, and the effect is similar to that ghost fire bomb, and it is safe. ”

Han Jiang nodded: "That's right, that's it, now after discovering the phosphate mine, my eldest lady is very happy, and the senior uncles and brothers of the Daomen are very excited, that is, several senior sisters have personally started it, I seriously suspect that they are researching a super powerful big guy, about one stone, which is used to blow up the city." ”

Liu Rui interrupted Han Jiang: "Let's continue to talk about Danfei." ”

"Well, there are two other kinds of Dan fertilizer, and the most suitable potassium fertilizer is chicken manure, which is still the old saying, which can be artificially refined. These need to be extracted from the ore and a pressure cooker is used. ”

Liu Rui asked: "What will happen if you use Danfei?" ”

"Half good and half bad."

"How can a good one be half bad?"

"Well, doubling the yield of the field is a normal degree, basically tripling up." As Han Jiang was talking, Liu Rui and Liu Guoteng stood up in a moment, they were stunned, and the grain output doubled.

Don't say it's the eldest lady of the Han family, if you change it to anyone, you will throw money into it desperately, even if there is only a little achievement, increasing the output by thirty percent is enough to leave a name for eternity.

Han Jiang was very calm: "The disadvantage is also great." ”

"How's that bad?"

Han Jiang knew the disadvantages of long-term use of chemical fertilizers, and replied: "The land will become worse and worse, and eventually it will rely on Shangdan fertilizer until the land is exhausted." ”

Liu Guo asked: "Is there a solution?" ”

Yes, but human nature is like this, and if there is understanding, there may not be anyone who works for this god. After easily doubling the yield, people forget the gift of the land. The solution is very simple, that is, to continuously pile humus, that is, dead leaves, compost, etc., instead of pure chemical fertilizer. ”

Liu Rui laughed: "What's so difficult about this, establish an agricultural law." Whoever abuses Dan fat, the whole family is sent to the frontier as slaves. ”

Simple, brutal.

However, it works.

Liu Guo said: "A new object from research to production, it always takes a few days, even if the workshop wants to let the whole world use Dan fertilizer, I am afraid that it will not be possible without a hundred years, and the output determines the use." But there will always be a day when the output will be enough for the people of the world to use, and it is indeed necessary to plan early. ”

Han Jiang raised his head: "There is one thing, I have been putting up with not telling my eldest lady." ”

Liu Rui smiled and asked, "It must be something that can save the Great Song Dynasty?" ”

Han Jiang nodded: "Yes, there are dozens of super good fields in Liaodong, each with a hundred thousand hectares, which has accumulated a humus layer for thousands of years, and thousands of years of dead branches and leaves have formed a soil layer nearly one zhang deep by the power of heaven and earth. ”

"Black earth."

Liu Rui patted Han Jiang lightly on the shoulder: "Don't worry, the old man may not be able to see it in his lifetime, but the old man's son and nephew will let you stand on that black soil, and will let your farmer build the granary of the world." ”

Han Jiang nodded heavily.

Talk on both sides.

Huainan East Road.

The troops responsible for besieging and killing Xu Zhiguo went home separately.

The blind dog also went home.

The blind dog returned to Yangzhou City and ran for two days before returning home.

In two days, the blind dog invited all the help of the officials and underground in Yangzhou City, and even Wang Xilu personally helped him intercede.

At home, the blind dog's mother was giving the blind dog the soles of his shoes, and the blind dog entered the house and knelt down, holding a cloth bag in both hands, and when he opened the corner of the cloth bag, he could see a green stone.

The blind dog's mother was stunned, and then pounced on it, and hugged the green stone tightly.

But when I touched it again, it was a little lighter.

Open the cloth bag, this piece of inkstone with a corner left, a green inkstone.

Tao Yan.

Although a corner is broken, it is still the same one back then.

This was left by the blind dog and his father, and it can be regarded as a family heirloom, and it was once a scholarly family. That year, I really couldn't survive, so the blind son of a girl sold this inkstone.

After changing hands several times, it was accidentally broken.

In this way, Wang Xilu still came forward to buy it back at ten times the price, in order to fulfill the blind dog's filial piety.

The blind dog spoke: "Mother, my son is not filial, my son has to travel far away, and he will go for ten years." To borrow a phrase from the sovereign: If you don't go back, you won't go back. ”

The blind didn't say a word, she had been observing these days, and she knew that her son had changed.

His own son knows for himself.

In the past, Ah Dog didn't like to read, he liked to fight and kill, and he was righteous. Now Ah Dog is more rational, and he has begun to learn to read, judging from the guests who come and go at home, his son has been learning, and he is constantly learning about the world.

Son, grown up.

The blind dog knelt on the ground: "Mother, I want to go to Mr. You'an to serve." ”

Xin abandons the disease, and the thief is also.
