"It's out...... Come out......" The little black thin man Du He excitedly waved the record in his hand, and ran towards Li Yuanjing and Li Shimin frantically.

After half a year of hard work, dealing with feces every day, he finally waited for the result he had been waiting for for a long time.

"How much?" Li Shimin also stopped talking with Li Yuanjing and set his eyes on Du He.

For Du He, Li Shimin also has some admiration, the descendants of meritorious deeds can actually suppress their temperament and squat in the field for half a year, and they still deal with dung.

The eldest grandson was canonized as the county prince of Ankang as early as two months ago, and the technology of blast furnace iron smelting is not too much to give a county duke, but the eldest grandson Wuji persuaded Li Shimin, which lowered the reward of the eldest grandson Jun by one level.

"Less than six stones! According to previous years, there are about five stone after drying, and the yield of this land in previous years is about four stone. This year has been a bit dry, and the yield is a stone's higher than the surrounding land that is not composted! Du He said excitedly.

The yield per mu of Shangtian is about four stones, and the yield of Xia Tian is not even one stone, and the output of the entire Datang during this period is only about three stones.

And there is also a problem to consider, this average yield is counted for all crops, for example, high-yield soybeans are also included, but people do not eat soybeans very much, these are basically used as livestock rations.

So if you convert it, the average yield of human rations such as corn is actually not high.

"Good! Good! Good! Li Shimin excitedly said three times in a row, there is a planting method for the upper field, and there is a planting method for the lower field.

After the waterwheel is popularized, it can ensure that more middle and lower fields get water, but the only defect is the problem of fertility, and now this problem has been solved, if this method is promoted throughout Datang, Li Shimin can almost imagine that Datang will never be short of food again.

"Your Majesty, start doing this right now, if it can be completed within half a month, and it will be almost used when the autumn ploughing is time, this time next year will definitely be a bumper year." Du He hurriedly reminded.

"Good! I'll arrange it when I get back to the palace! Li Shimin's face turned red and nodded, and he immediately glanced at Du He, and said, "You will go back to the palace with me in a while!" ”

The important information is in the hands of Du He, even if it is promoted, it is necessary to hand over the technology to other people first, and only one Du He can only operate it in the Huangzhuang at most.

Li Yuanjing smiled on the side and said nothing, in fact, there was nothing to say.

The little brothers who followed him are now considered to have a successful career, and Li Yuanjing suddenly found that his life seemed to be a little boring.

It's been a year since I came back, and I've been busy protecting myself every day, or engaging in people, and I haven't really enjoyed a good life in Datang.

"Yuan Jing, I plan to directly cast iron farm tools!" Li Shimin said with confidence.

Everyone knows the benefits of iron farming tools, but in the past, it was limited by the lack of iron production, so no one could use iron to make agricultural tools.

But now it is different, with the mastery of blast furnace technology, it is only necessary to build blast furnaces in various places, and one blast furnace can make thousands of iron agricultural tools in a day.

Farm tools are different from weapons, farm tools can be cast directly, and then taken back to open the blade can be used, but after the weapon is cast, the craftsman needs to hammer it again, otherwise the hardness is not enough, and it is difficult to take advantage on the battlefield.

"It is better to set up a separate yamen to be responsible for this matter, the price of farm tools must be low, not to mention to ensure that every household can buy, at least to ensure that every two can buy a one, as for sales, my opinion is that the county government will sell, the imperial court will set a unified price, and it is not allowed to buy and sell, in addition, the imperial court can also appropriately release the rumors, and will send the imperial history to conduct secret visits, which will be an important factor in the evaluation in recent years." Li Yuanjing thought for a moment and said.

He didn't plan to get involved in this matter, he was too tired to talk about it, and he didn't make money.

As for whether local officials will be greedy for ink or change policies privately, Li Yuanjing also feels that he doesn't need to worry about it, and naturally some people in the DPRK and China will think about these things.

"Hmmm! I'll think about it! Li Shimin nodded, this is indeed a way.

Officials are most concerned about the annual evaluation, if the evaluation is not as good as that of colleagues, then when the term of office is reached, they will fall into a disadvantage when they are promoted in the future, unless there are people in the court, otherwise it is difficult to say what the career will be, and it is even possible to be dismissed.

This trip was connected to several good news, so that Li Shimin's mind had already flown back to Chang'an.

With the support of experimental data, the weaving mill made a second improvement to the loom, and the output was further increased, and the blackstone was processed into coke, although it was not smelted into steel, but it was no longer pig iron, but wrought iron, indicating that this idea was feasible.

One good news after another, Li Shimin was a little overwhelmed, especially the problem of composting, he felt that he couldn't delay, and hurriedly took Du He to gallop back to Chang'an on horseback.

……

It wasn't until Li Shimin left that Cheng Chuliang and Fang Yiai, who had been dodging, dared to show up.

"Your Highness, it's not very easy to do...... Cheng Chuliang handed a piece of paper in his hand to Li Yuanjing with a sad face.

Looking at the content recorded on the paper, Li Yuanjing couldn't help frowning.

His idea of dealing with the family is to implement it from economic means, and when the economic suppression of them reaches a certain extent, Li Shimin is taking action to suppress them politically, attacking from both sides, and the effect will not be too bad.

But now Li Yuanjing felt that his plan seemed a little reckless.

The Zheng family, including the industrial situation of several other companies, can be investigated through Liu Hu, and there is basically no big difference, but the relationship network of each family is not something that Liu Hu can find.

Cheng Chuliang and Fang Yiai had been going to engage in this information before, as for where to do it, of course, they went home to find their father to understand, and then the two of them summarized it and removed some duplicates, which led to the current list.

Well, the five surnames are Qiwang, except for Er Li, the other four surnames say that they are a family, and there is no big problem.

The marriages of all the important people in the family come from one of the other three surnames, and outsiders who want to enter the family as wives should not even think about it.

Their arrogance is not just talk, even Li Shimin wants to marry a woman from a family as a concubine, they don't sell this face.

However, on this complex list, there are hundreds of intersecting relationship networks, and such intensive marriage methods have long connected them into one.

Dealing with the Zheng family in the past could only be regarded as a small fight, and for the sake of face, the Zheng family did not let several other families get involved.

But if you want to do a big thing, you have to face the five of them at the same time, and your own small body......

Li Yuanjing subconsciously shook his head and sighed: "This matter will be discussed for a long time, we have been busy for so long, let's go to Chang'an to relax first!" ”
