"Can this be?"

Above the court, Dai Xuan looked at Du Ru talking eloquently, and couldn't help but sigh.

As soon as he went to court today, Du Ruhui raised the issue of passive breeding after people in various places recently received duck seedlings.

Then a set of solutions is given.

The analysis of people's labor costs, time costs and expected benefits can be said to be unheard of, but when you think about it, it makes too much sense.

Now people can only be exempted from ten days of forced labor if they raise ten ducks, and then under Du Ruhui's calculations, the labor cost and time cost of raising ten ducks far exceed the impact of ten days of forced labor on people's income.

Everyone also reads the Four Books and Five Classics, why is Brother Keming suddenly so good?

"All men seek profit, let it be profitable!" In the end, Du Ruhui concluded: "The people spend hundreds of dollars and get ten dollars, how can they make it? ”

"The minister seconded the proposal!" Fang Xuanling stood up: "Being a pet and carrying a high position, having a warm family and eating a generous meal, because of the wealth and wealth, in order to compete with the people for the next advantage, the people's security can be as good." ”

Then several courtiers agreed, of course Li Shimin had nothing to say, only a few core members of the Tang Dynasty knew about this matter, and the real purpose was to restrain the locusts and alleviate the upcoming locust plague.

If the duck farmers themselves are passive and do not let the ducks go out to hunt more locust larvae, then the duck seedlings they exchange for iron ore will completely lose their original meaning.

It's just that why did Du Ruhui suddenly know so many things? Li Shimin looked at Du Ruhui frequently on the dragon chair, and he was puzzled.

"Du Xiang, Your Majesty is invited!" After retiring from the dynasty, Du Ruhui was stopped by an attendant.

Fang Xuanling gave him a look, Du Ruhui nodded, and followed to the Hall of Virtue.

"Keming, sit!"

"Don't dare!" Du Ruhan bowed: "What the court said today is not what the minister thought of!" ”

You must know that in the court, Li Shimin praised Du Ruhui a lot at that time, and it was inconvenient to say it at that time, but if this will not be explained clearly, then it is really suspected of bullying the king.

"Oh? I don't know who Keming listened to? In fact, when Du Ruhui said it just now, Li Shimin was suspicious.

Because many words are not what this Datang should have, and the place where such words have appeared the most recently is Shanghe Village.

"It's what a little girl in Shanghe Village said!" In fact, Du Ruhui blushed a little.

It's not a day or two that the people are not very enthusiastic about raising duck seedlings, but the Manchu civil and military forces can't come up with a good way to do it alone.

The reason for this is the idea that the ass decides the head.

Everyone is in a high position, and they all feel that it is already a kindness to be exempted from ten days of forced labor, and it is a matter of course for the people to help the court raise ducks, so they don't think about improving the people's income at all.

"A little girl?" Li Shimin was also stunned for a moment, and then suddenly realized: "Hahahaha, are those students of Tang Ping?" If you guessed correctly, it should be Erya! ”

He has been to Tang Ping a few times, and he has also seen Tang Ping go to class, and he has paid special attention to the person named Er Ya in Tang Ping's group of children in Shanghe Village, that girl is indeed astute, and she learns everything faster than others, and among Tang Ping's students, she is second only to Li Bai.

Du Ruhui nodded yes, but he already knew in his heart, His Majesty knew so much about Tang Ping in Shanghe Village, it seemed that his and Fang Xuanling's guess was really not wrong.

It's just that now Datang has set up Li Chengqian as the crown prince, and I don't know that there is an extra illegitimate son with such a talented person, which is sometimes good and sometimes bad for Datang!

The two chatted for a while, and Du Ruhui was let out, just like Fang Xuanling, after coming out, he was already in a cold sweat, involving the royal family's fortune, and every word had to be cautious.

And he was very much looking forward to meeting Tang Ping in Shanghe Village yesterday, but now he has extinguished this idea.

He is in the phase, Tang Ping is sensitive, and he still has little to do with him!

Li Shimin criticized Du Ruhui's recital, and he was also a little worried.

His own prime minister, why do they like to go to Shanghe Village when they go out of the city? Is Feng Shui good or what's wrong there?

But you can't order that no one is allowed to go there, can you? Isn't that trying to cover up?

After thinking about it, I didn't come up with a good solution, so I could only go with the flow for the time being.

Only Tang Ping, the person concerned, doesn't know that he has actually become an illegitimate child in the mind of "Fang Mou Du Xuan".

I didn't know that I had actually made a lot of waves in the court.

He's going to be looking at a set of numbers in his system.

"Sora, what does this 1568 mean? Hey, it's 1602 again! ”

"This is your progress in promoting math, this task can be finished at any time, and the reward will be settled according to the data at the end."

"That means that now because of me, these mathematical theories have begun to be promoted, and the more they go to the back, the greater the impact, and the better the rewards, right?"

"Yes!"

In this way, Tang Ping understood, anyway, he is not in a hurry to ask for any reward now, just let it hang like this, just like an idle game on a mobile phone, and then collect it when you need resources, that is, this reward is a blind box, what it is, I don't know now.

Soon, a piece of paper was sent to all parts of the Tang Dynasty, and half of the ducks raised by the imperial court were handed over after half a year, and the remaining half was solved by each family by themselves.

As soon as this document arrived, many people couldn't believe it, and after confirming it again and again with the officers in the yamen, they were sure that this was actually true.

"Go, make some bamboo fences, fence off our fields, put the ducks in them, they like to eat insects, and then surround them after eating!"

"Sanwa, go and call your brother to go to the river to catch some river shrimp to feed the ducks!"

"Dad, do you think these earthworms I dig can feed the ducks?"

Just like Du Ruhui said, the world pursues profit to make it, and all of a sudden, those who received the ducks were enthusiastic, and the court provided duck seedlings, and they could take half of them away by only being responsible for raising them.

Even if some ducks may die halfway, it is more cost-effective than the original ten days of forced labor!

And many people who had not received the duck seedlings and laughed at their neighbors for their thankless work also went to the local yamen to ask if they could still get them.

After learning that raising ducks would become the norm in half a year, he left in a huff.

Yes, this time the high-level of Datang discovered the sweetness of the breeding industry through calculations, so of course it will be promoted for a long time in the future.

Even Menxia Province is already considering not only being limited to chickens and ducks, but all kinds of poultry and livestock can adopt this new model of state-individual joint breeding!
