When Emperor Chongzhen heard this, he was stunned for a moment, and seemed to think seriously for a while before saying: "It seems that there is such a thing, about ten years ago." I remember that at that time, the ministers all said that the fish and turtles in the Zedwelling, the elk in the mountain dwelling, and the living Huainan was orange; Born in Huaibei, it is citrus. The leaves are similar, but the taste is different......"

Speaking of this, he paused before adding: "Rice and wheat are cultivated for thousands of years, and if we rashly replace them with sweet potatoes, we are afraid that more people will starve to death." In addition, the state affairs were erosive at that time, so the final conclusion of the imperial court was not possible for Xu Qing's performance. ”

After finishing speaking, Emperor Chongzhen looked at Zhang Mingwei and asked with a little surprise: "Sir, this thing is really better than rice and wheat and other things?" ”

Since ancient times, there has been a deep-rooted impression that a certain creature should only exist in a certain area, and if it is transferred to another place, it will be restricted by water, soil, climate, etc., and it will either die or deteriorate.

Emperor Chongzhen just explained, which is probably what he meant.

It is precisely this concept that is so common that Xu Guangqi even emphasized this matter in the preface of Sweet Potato Shu, saying that Sweet Potato would be an exception. However, judging from the results, he still did not change the impression of Emperor Chongzhen and the hundred officials. Coupled with the headache of thieves and Jianyu up and down, no one wants to try. And Xu Guangqi died in the early years of Chongzhen, and this matter is over.

When Zhang Mingwei heard this, he frowned and thought, or this is because the court, including Emperor Chongzhen himself, is not like Xu Guangqi who will personally serve the farmland, so they only believe what the book says, and they have not been able to change their inherent impression.

Thinking of this, he couldn't help sighing, and said to Emperor Chongzhen seriously: "This sweet potato is a great weapon for disaster relief!" It is possible that the sweet potato at this time has not been improved, and it may not have a high yield per mu in later generations. However, the most important thing is that this sweet potato can be planted not in the field, but in the mountains or anywhere. It is a powerful supplement to farmland planting. If Your Majesty were to promote it with all his might, many people would inevitably starve to death! ”

"Huh?" When Emperor Chongzhen heard this, he was immediately shocked, and then his face was full of remorse. If he had known that he could not occupy farmland, maybe he would have been allowed at that time!

What the Ming Dynasty lacked the most was the lack of food! If there was food, it would not have reached the point where the country is going to die now!

No matter how remorseful he was, Zhang Mingwei turned his head and instructed the crown prince Zhu Cihong: "After you go to Nanjing, immediately look for experienced old farmers who grow sweet potatoes, and make every effort to promote them in the southern provinces, do not occupy farmland, and remember to cultivate excellent varieties." ”

Of course, Zhu Cihong also knew that this matter was very important to Daming, so he nodded seriously and said, "Sir, I wrote it down!" ”

Emperor Chongzhen listened to it on the side, and also instructed Zhu Cihong very seriously: "If the magistrate is perfunctory, he must deal with it seriously!" ”

Zhu Cihong listened, and of course nodded again.

As for the northern side, there are military disasters everywhere, and it is too difficult to promote sweet potatoes, so let's slow it down for a while.

Zhang Mingwei continued: "There is also a high-yield crop, which does not occupy farmland, which is very suitable for cultivation in the north, and the yield in the cold zone is very high. It's called a potato, and it should have been introduced to Daming from Fanbang at this time. When the prince arrives at the place, he must go all out to find this kind of potato so that it can be promoted in Daming! ”

When Emperor Chongzhen heard the great joy, without waiting for Zhu Cihong to answer, he grabbed Zhang Mingwei's hand first, and confirmed loudly and happily and hurriedly: "Is this true, sir?" ”

If he is worried that the sweet potato from Fujian may have problems in the north, what kind of potato is he talking about now, Zhang Mingwei emphasized that it is very suitable in the north, then there is no previous worry, how can he not be ecstatic!

Zhu Cihong was also very happy, but he immediately made a mistake: "Sir, I don't know what this potato looks like, how can I find it?" ”

Sweet potatoes are already common in Fujian, so he is not worried, but no one has heard of this potato before. That's why he asked.

"I'll show you a rough picture!"

As soon as Zhang Mingwei finished speaking, Emperor Chongzhen immediately led him to the imperial case, and personally picked up the imperial pen and held it with both hands. Princess Kunxing, who had been listening silently, was also very conscious of being a maid, and immediately went to polish the ink.

Zhang Mingwei took the brush and looked at it, and said a little embarrassedly: "The brush only learned a little in elementary school, and later it will be used with ballpoint pens and pens. ”

After that, he began to draw potatoes on the imperial rice paper.

Zhang Mingwei is from a rural area, and he is no stranger to potatoes and sweet potatoes. So, the potatoes and leaves that he drew had a rough idea. But if you want to say how similar it is, it is not necessarily true.

Emperor Chongzhen and others, as soon as they saw Zhang Mingwei's gesture of holding a brush, they knew that he could not write with a brush.

However, no matter who it is, they don't have the slightest contempt for Zhang Mingwei. Because they all think that brushes are like knives and guns, and what Zhang Mingwei said about ballpoint pens and fountain pens is like the artillery they saw in the documentary, and they must not be compared. So, how could future generations use brushes again!

After the painting, Zhang Mingwei explained to the three onlookers. Then, I don't know why I held the pen just now, so I subconsciously stretched and yawned.

Seeing him like this, Princess Kunxing suddenly came back to her senses and said to Emperor Chongzhen in surprise: "Father, I'm afraid it's already the third watch now." ”

Emperor Chongzhen had already come back to his senses when Zhang Mingwei yawned. However, he was excited, and he couldn't get a little sleepy. But no matter what, Zhang Mingwei is already a little sleepy, and he wants to express it no matter how excited he is.

So, after thinking about it for a while, he asked Zhang Mingwei with respect: "Sir, why don't we sleep on our feet and talk for a while?" ”

"......" Zhang Mingwei was speechless when he heard it, and he slept in a bed with Emperor Chongzhen?

What he didn't expect was that Zhu Cihong actually said on the side: "Father, the son still wants to listen!" ”

It was really Zhang Mingwei's impact on them, and it was indeed too great. As long as there is a trace of curiosity, they can't help but listen more, and they don't want to miss a little bit of the news that Zhang Mingwei brought them.

When Zhang Mingwei heard Zhu Cihong's words, he couldn't help but turn his head to look at him, speechless in his heart: One more prince on the bed?

"Father, I want to hear it too!" Princess Kunxing heard Zhu Cihong speak, and she couldn't wait to follow the request.

But as soon as she said the words, she immediately realized something, and her face was flushed, and even her neck was red.

…………………

Besides, Wang Chengen went to interrogate Wang Dehua, although he had already been instructed to deliberately keep a low profile. But at this time, it was already night in the palace, and no matter how low-key things were, this movement could not be too small.

I saw a chamberlain walking quickly in the dim palace without even beating a lantern. After a while, he bumped into a group of people.

I saw two chamberlains lighting lanterns and lighting lanterns to a eunuch in a big red robe.

As soon as he saw this, the hurried chamberlain hurried over and whispered, "Godfather, it's not good, Godfather, something happened!" ”

When the eunuch heard this, he immediately stood up, looked at the chamberlain who had already arrived in front of him quickly, and asked, "What is the situation on the emperor's side?" What's going on? ”

He obviously heard that there was something abnormal on Emperor Chongzhen's side, and looking at him, he also rushed over to see the situation.

"Godfather, my son saw that Wang Dehua was taken away by Wang Chengen's people!"

"What?" When the eunuch heard this, he was immediately taken aback, "The lights are blind at night, can you see clearly?" ”

In fact, in his heart, he understands that it is absolutely impossible to make a mistake about such a big thing. However, Wang Dehua, the eunuch and the commander of the East Factory, said that he would take it if he took it, how angry would the emperor be?

"The specific situation, the son is not clear. just saw Wang Dehua hurrying to the emperor's side, and not long after, he was escorted out by Wang Chengen's people. ”

The eunuch listened for a while, and then immediately asked, "Did the emperor summon him?" ”

"It doesn't seem like it, it's supposed to be to see the movement, and then ......"

When the eunuch heard this, he immediately turned around and left, and at the same time spoke: "Inquire about this matter secretly, and then come to the imperial horse eunuch to report." ”

Obviously, he didn't understand the movement on the emperor's side, and was frightened by Wang Dehua's matter, and didn't dare to go again: what if he bumped into it headlong without knowing it, what if he ended up with Wang Dehua?
