In fact, in the Central Plains civilization, it is not only the various ideas and the four great inventions that lead the world, but also the arithmetic is also the world's top.

After the harvest in Yunnan, people with good intentions quickly calculated the output of those grains.

Corn is at least twice as large as rice and wheat, and potatoes are even more intimidating, more than ten times as much.

According to the third volume of the "Hejian Chronicles": "A husband cultivates fifty acres of land, and harvests more than one stone of wheat per mu." ”

It is said in the "Book of Supplementing Agriculture": "The field is extremely ripe, the rice is three stones, and the spring flowers are one and a half stones, and then there are them." Dayun has a total of three stones for Chang Er. ”

During the Ming Dynasty, one stone was about 150 catties, so the yield of rice was usually less than three stones, that is, about 400 catties, while the yield of wheat was lower, about two stones per mu, about 300 catties.

However, there is one point, which is the yield of a single season, and it is still taken from those good lands, that is, the highest yield.

What does that mean? In fact, in the south, there are usually two crops of rice, and there are still very few places where three crops of rice can be grown, among which the yield of early rice is lower, but these data are numerically taken from the yield of late rice with higher yield.

That is, the actual production is not so high, and these figures are even a little higher than the average.

But this is also very normal, especially in the court, this kind of thing is not uncommon, and there are even more outrageous than this, which is not a thing.

The output of potatoes can reach 3,000 to 5,000 catties in later generations, which is obviously unattainable in this era without chemical fertilizers and pesticides.

Zhu Zhanyan picked the best land and let people take care of it every day, and the final yield per mu was only about 1,000 catties.

This may have been very low for Zhu Zhanyan, but it was terrifying enough for others.

What? How do you say those people determine the grain?

Preconceived notions, in this era, the most important thing is food, there is enough food, coupled with the right time, it is not impossible to overthrow a dynasty.

Zhu Zhanyan spent so much effort to arrange people to enter the market, and the loss of this trip was so big, in the eyes of those people, it was impossible to do anything other than food.

Even, from the perspective of Huang Huai and others, this is already a precursor to the rebellion of the Han Dynasty.

But!

It's a threat to Huang Huai and others, but what about Zhu Gaochi? Is it also a threat to him?

Don't forget, in this world, the surname is Zhu.

……

Qianqing Palace.

"Is this true?" Now Zhu Di no longer has the light breeze on weekdays, and his face is full of nervousness.

"Back to Your Majesty, the yield can already be determined, but is it grain...... This is yet to be investigated. ”

"However, His Royal Highness the King of Han is watching too closely, if you don't startle the snake, I'm afraid it will be ......"

"Don't worry, it's the same as before!" Zhu Di waved his hand and made a decision very simply.

"Yes!" Ji Gang chuckled in his heart, and his evaluation of King Han's father and son was one level higher.

In the past, people always thought that the king of Han was gone, and he lost the possibility of competing for the crown, although with Zhu Zhan Yan did several major things in a row, people's minds have changed, but it is still not very thorough.

After all, Zhu Di's attitude is more ambiguous and unpredictable.

You said that he wanted to make the Han king's lineage competitive, he let the Han king go to the domain, but you said that he wanted the Han king's lineage to have no chance at all, and he kept giving the Han king preferential treatment.

And now, Ji Gang has finally made this answer clear today.

can repeatedly let go of such things as food, if it is a different person, it is estimated that it will either be taken over by the imperial court or there will be no corpse.

There is only one lineage of the Han king......

"By the way, how is the prince's side?" Zhu Di didn't know what Ji Gang thought, and then asked him a question.

"Back to Your Majesty!" Ji Gang quickly retracted his thoughts and lowered his head to report.

"Previously, Xie Jin, Huang Huai, Yang Rong and Yang Shiqi went to see His Royal Highness the Crown Prince after getting the news from Yunnan, among which Xie Jin and Huang Huai were more excited, and Yang Rong and Yang Shiqi were relatively calm."

"As for His Royal Highness the Crown Prince, there was no reaction, but instead reprimanded Xie Jin and Huang Huai."

"Well, I know, stand down."

"Yes!"

Ji Gang slowly withdrew from the Qianqing Palace, and the attendants and palace maids guarding the door did not dare to enter casually.

In the Qianqing Palace, Zhu Di sat alone on the chair that symbolized supreme power, holding his forehead and pondering.

——

Henan, Zhangde Mansion, the place where Zhu Gaosui, the king of Zhao, took possession.

Placing the letter paper in his hand on top of the candle flame, Zhu Gaosui quietly watched it slowly turn to ashes.

"Second brother, are you really good......"

"Are you sure you can, though?"

"If there is no Zhan Gully, and the current Zhan Gully is afraid to be ......"

……

Wa country, Bo Qi.

As the temperature slowly warmed up, Zhu Zhanyan's push slowed down, not because he didn't want to be fast, nor because the morale of the soldiers was insufficient, but because he had to do it.

He had slaughtered the nobles and samurai class of Iwami before, and the great feudal lord of Iwami was naturally gone, and this Iwami Silver Mountain became an ownerless piece of fat in the eyes of other great feudal lords of the Japanese Kingdom.

What? Ming army?

Don't be funny! Can they be stationed here forever? I am afraid that at this stage, there is no better understanding in the world than their Japanese countries about the cost of transnational and cross-sea operations.

After all, they were responsible for the troubles of North Korea and the Ming Dynasty.

Therefore, those big feudal lords planned to gather together and use their collective strength to attack the Ming army, so that the Ming army would retreat in the face of difficulties, and then they would divide the stone and silver mountain.

But unexpectedly, they mistakenly substituted their combat power for the Ming Dynasty during the period of the Japanese Invaders.

When they plundered the Daming Sea Frontier, they were all surprise attacks, and when the Ming Dynasty's prepared Japanese army did not react, they left after robbing, but now?

The soldiers of the Ming army waited for each other night and night, and in the event of a war, they were able to enter the battlefield at what can be said to be the fastest reaction speed of human beings.

This is the origin of the Kyokan Temple next to Lake Shinji.

But these were not Zhu Zhanyan's original intentions, because what he wanted now was to squeeze the value of the Japanese people as much as possible.

In Iwami, he asked the Japanese people to work as miners and mine silver for the Ming Dynasty; In the places where he first landed, he let the Japanese people farm the land, and then "inadvertently" lost control of these places.

Then, the big feudal lords of Okuma, Hinata, Higo, and other places would fight back, and after occupying those places that the Ming army had "lost", they would conscript troops and levy food.

Then, the Ming army slaughtered the horse pistol, killed the elite and the samurai class, and took away the supplies and weapons and equipment of the Japanese army as captured, and "liberated" the Japanese people.

This is a sustainable development plan, which is the purpose of Zhu Zhanqi, and the Jingguan of Shinji Lake is obviously not in line with this plan.

"His Royal Highness!" Just when Zhu Zhanyan was thinking about a solution, Zhu Ling's voice came in, but his words revealed full of anxiety.

"Your Highness! Letter from His Royal Highness the King of Han! ”

"Huh?" Zhu Zhanyan frowned, and then quickly relaxed.

After receiving the letter, Zhu Zhanyan opened it and looked at it twice, and then threw it aside.

There is nothing to do, but his father told him about the recent situation in Yunnan, and the most important thing is that those seeds have been harvested, and secondly, Siam is a little restless.

Before Zhu Zhanyan escorted Chen Jikuo to Yingtian, he deliberately let his grandson go, and Zhu Zhanyan originally felt that the child couldn't live, after all, he was alone and in that kind of place.

But unexpectedly, this child didn't know how to run to Siam.

Siam didn't make any big moves, but the fact that he received Chen Jikuo's grandson was enough to make Mu Sheng vigilant, but Zhu Zhanyan was not in Yunnan, so he could only tell Zhu Gaochu the news, and Zhu Gaochu passed it on to Zhu Zhanyan.

Zhu Zhanyan picked up the pen and quickly wrote two letters and handed them to Zhu Ling.

"This letter is sent to the family, and this letter is sent to Yingtian."

"Yingtian?" Zhu Ling was stunned for a moment, and then asked in an uncertain tone.

"Your Royal Highness, what do you mean by Yingtian......"

"It's okay to send it to the emperor's grandfather, or to the uncle." Zhu Zhanyan said without raising his head.

"Don't worry too much, it doesn't matter if people see it."

"Yes!" After receiving a definite answer, Zhu Ling left in response.

"Whew......" Zhu Zhanyan let out a sigh.

"Zhu Ping! In! ”

"His Royal Highness!"

"What about the Japanese man who knew Chinese before? Let him go find some Japanese people, give them money, and let them go to Inaba, Misaku, and other places to buy some things for us. ”

"Huh?" Zhu Ping was stunned.

"Ahhhh Let you go, you will go! ”

"Yes!"

Zhu Zhanyan rolled his eyes angrily, recently he found that his two guards were talking more and more, but it was also true that his recent behavior was becoming more and more unexpected.

But there is no way, now he is killing is cool, since the beginning of the Eastern Expedition to the Japanese Kingdom, the new souls under his name are not 500,000 but 400,000.

That's it, it's still a conservative estimate.

Now that he has entered a period of calm, he has begun to plan for greater gains, especially to prepare for the future Sado Kanayama.

That golden mountain has not been discovered yet, but it is a good thing, and it is an important part of Zhu Zhan's plan in the future.

Yinshan let go, Jinshan has to give it a try, even if he can only get a part.

But because of this, many of the orders he gave were incomprehensible, after all, the ideas of those soldiers were relatively simple, and they were only keen on military merits.

For example, this time, he asked Zhu Ping to select some Japanese people to help the Ming army procure, does the Ming army need their procurement?

Since the last time Zhu Zhanyan rushed into the Korean palace and forced Li Fangyuan to hand over the prince's son Li Zheng, no one in North Korea or the Ming Dynasty dared to provoke Zhu Zhanyan again.

Li Fangyuan's experience let everyone know, if you dare to pull Zhu Zhanyuan back, he really dares to get you.

This last time was Li Fangyuan, the size is the lord of a country, if you change people, it is estimated that someone on the grave will give you the incense of the last anniversary.

In addition, Zhu Gaosui also went to the domain, who would dare to cut off Zhu Zhan's supply?

There is no shortage of supplies, why should the Japanese people go to help the Ming army procure? What else are you going to buy? Don't say it's Zhu Ping, I'm afraid everyone doesn't understand.

In fact, Zhu Zhanyan wanted to let those Japanese people spread the news, although he didn't say it, but he only needed to work in the mine to be exempt from taxes, and there was also a salary to pay, this kind of life was already the best life in the hearts of ordinary people.

Although Zhu Zhanyan never mentioned it, if these people went to other places, some people would definitely be tempted to talk about it with the locals.

Over time, the news will spread, and the resistance to Zhu Zhan's follow-up will become smaller, and it will be easier to let those Japanese people do absenteeism in the future.

The last time I asked the soldiers to spread the news, the Ming army suffered some losses, and this time Zhu Zhanyan didn't want to repeat the same mistakes.

"Someone! Chuan Liu Sheng and Wang Jinghong came to see me! ”

Thinking of this, Zhu Zhanyan felt that he could start to prepare, and now his next target in Boqi would definitely be Inba, and the Shenji Battalion and the fleet would come in handy at that time.

……

Yingtianfu, Imperial Palace, Qianqing Palace.

Zhu Di looked at the letter sent back by Zhu Zhanyan, his face was dumbfounded.

Although he had long thought that the things that Yunnan had grown before were grain, he still habitually put them aside until he got a definite answer.

Now, he has been confirmed by Zhu Zhanyan himself, and although the impact on him at this time is a little smaller, it is still difficult for ordinary people to bear.

Imagine what it would be like if one day, Daming's overall grain production increased by five or six times or more?

Undoubtedly, the first is the stability of the society.

In the early years of Yongle, rebellions broke out, and almost every year someone broke out, what was the reason? Except for a few people at the top who are in it for power and money, most of the others are in it to get enough to eat.

When the grain production comes up and the people are satisfied with the rule of the imperial court, the disappearance of such a situation may not disappear completely, but it will definitely decrease a lot.

After all, the people's idea is simple, they just want to be fed and clothed, and then raise one or two children, which is what they want all their lives.

After getting food and clothing, the people rarely do things like uprisings, which are very likely to lose their lives and may lead to not having enough to eat.

You must know that even if you count all dynasties, there are few things in the entire history that can keep the people fed and clothed, and they can all be recorded in history, such as the rule of Wenjing and the like.

Second, an increase in food production will also lead to population growth.

When the grain production comes up and the people have a surplus in their families, the first thing to consider is to pass on the lineage.

For the Ming Dynasty, the increase in population means that productivity will increase, and the source of troops will also increase.

Finally, there is the war aspect.

The increase in food production will lead to an increase in population, and will provide new sources of troops for the Ming Dynasty, although the cycle is very long, but it is also worth looking forward to, in addition to another very important issue: supply.

With sufficient supplies, what Tatar Warat, whoever dares to jump on the Ming Dynasty will dare to fight whom!

It is no exaggeration to say that with this kind of high-yield grain, Zhu Di is confident that he can defeat any country in this world!

Some people may think that Zhu Di is a little suspicious of thinking too much about these things now, after all, things are still in Yunnan now, and Zhu Gaoxu looks at it very closely, but he is the emperor.

Without saying an order, Zhu Gaochu has to send him something, even if he is reluctant, even if Zhu Gaochu has a lot of dissatisfaction in his heart, can he still disobey the emperor's order?

Besides, Zhu Zhanyan had already said in the letter that after enough seeds were cultivated in Yunnan, some of them would be sent to Yingtian.

Spread everything out, that's the best thing to do.

This kind of self-cutting back road will be confused by whoever comes.
