Emperor Chongzhen was a little stunned when he heard this, as if he had thought about it carefully for a while before saying, "It seems that there is something happening, about ten years ago. I remember that at that time, all the ministers said that fish and turtles in the zen, elks in the mountains, and those in the south of Huai, were oranges; those in the north of Huai, were tangerines. The leaves are similar, but they actually taste different..."

Speaking of this, he paused before adding: "Rice, wheat and other things are grown for thousands of years. If you rashly replace sweet potatoes, you will be afraid of starving more people to death. In addition, the state affairs were corrupt at that time, so the court finally concluded that Xu Qing's report was not allowed."

After saying that, Emperor Chongzhen looked at Zhang Mingwei and asked in surprise: "Sir, this thing is really better than rice, wheat and other things?"

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

Emperor Chongzhen just explained it, probably this is what it means.

It is precisely because this concept is too common that Xu Guangqi even emphasized this matter in the preface to Sweet Potato Spray, saying that Sweet Potatoes would be an exception. However, judging from the result, he still did not change the impression of Emperor Chongzhen and all officials. In addition, the top and the others were both worried about the bandits and Jianlu, and no one was willing to try it. Xu Guangqi passed away in the early years of Chongzhen, so the matter was left to nothing.

When Zhang Mingwei heard this, he frowned and thought, maybe this was because the court, including Emperor Chongzhen himself, was not personally serving the farmland like Xu Guangqi, so they only believed what was said in the book and failed to change their inherent impression.

Thinking of this, he couldn't help but sigh and said to Emperor Chongzhen seriously: "This sweet potato is a powerful tool for disaster relief! It is possible that the sweet potatoes at this time have not been improved, and may not be as high as those in later generations. However, the most important thing is that this sweet potato can be not planted in the fields, but in the mountains, and it can be all. It is a powerful supplement in addition to farmland cultivation. If Your Majesty promotes it with all his might, many people will definitely starve to death!"

"Ah?" Emperor Chongzhen was shocked when he heard this, and then he looked regretful. If he had known that he would not occupy the farmland, he might have been sure at that time!

What the Ming Dynasty lacked the most was food! If there was food, it would not have reached the point where the country was about to be destroyed!

No matter how regretful he was, Zhang Mingwei turned around and instructed the prince Zhu Cilang, "After you go to Nanjing, immediately look for experienced old farmers who grow sweet potatoes, promote them in the southern provinces, do not occupy farmland, and remember to cultivate excellent varieties."

Of course, Zhu Cilang knew that this matter was very important to the Ming Dynasty, so he nodded seriously and said, "Sir, I have recorded it!"

Emperor Chongzhen listened to Zhu Cixuan very seriously: "If the local officials are perfunctory, they must be dealt with seriously!"

When Zhu Cilang heard this, of course nodded again.

As for the north, there are war disasters everywhere, and it is too difficult to promote sweet potatoes, so let it go first.

Zhang Mingwei continued: "There is also a high-yield crop that does not occupy farmland. It is very suitable for planting in the north. The yield in the cold areas is very high. It is called potatoes. At this time, it should have been introduced to the Ming Dynasty from the foreign countries. When the prince arrives at the place, he must make every effort to find this potato so that it can be promoted in the Ming Dynasty!"

When Emperor Chongzhen heard this, he was overjoyed. Before Zhu Cixuan could answer, he grabbed Zhang Mingwei's hand first, and confirmed happily and quickly, "Sir, do you think this is serious?"

If he was worried that the sweet potato originating from Fujian might have problems in the north, what potatoes are mentioned now? Zhang Mingwei emphasized that it is very suitable in the north, then there would be no previous worries. How could he not be ecstatic?

Zhu Ciyang was also very happy, but he immediately thought: "Sir, I don't know what this potato looks like, how should I find it?"

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

"I'll show you a rough idea!"

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

Zhang Mingwei took the brush and looked at it, and said a little embarrassedly: "I just learned a little in elementary school. I always use ballpoint pens and fountain pens. I really don't know how to use this, I laughed at you."

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

Zhang Mingwei is from a rural area and is not unfamiliar with potatoes and sweet potatoes. Therefore, the potatoes and leaves he drew probably look like. But if you want to say it is very similar, it may not be necessary.

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

However, no matter who it is, they have no intention of despising Zhang Mingwei at all. Because they all think that brushes are like swords and guns, and what Zhang Mingwei said about ballpoint pens and fountain pens are like cannons they see in documentaries, and they are definitely incomparable. So, how could people in later generations use brushes again!

After finishing the drawing, Zhang Mingwei explained to the three people watching. Then, he didn't know why he was holding the pen just now, so he subconsciously stretched and yawned.

When Princess Kunxing suddenly came to her senses and said to Emperor Chongzhen in surprise: "Father, I'm afraid it's already the third day now."

Emperor Chongzhen had already come to his senses when Zhang Mingwei yawned. However, he was excited and had no sleepiness. But no matter what, Zhang Mingwei was already a little sleepy, and he would like to express his excitement even if he was excited.

So, after thinking for a moment, he asked Zhang Mingwei with respect, "Sir, why don't we sleep and talk for a while?"

"..." Zhang Mingwei was speechless when he heard this, and he slept in the same bed with Emperor Chongzhen?

What he didn't expect was that Zhu Cilang actually said beside him: "Father, my son still wants to listen!"

The impact Zhang Mingwei brought to them was really too great. As long as you have a little curiosity, you will not help but listen more and do not want to miss any news Zhang Mingwei brought to them.

When Zhang Mingwei heard Zhu Ciyang's words, he couldn't help but turn his head to look at him, and he was speechless: There is another prince on the bed?

"Father, I want to listen too!" Princess Kunxing couldn't wait to ask for it when she heard Zhu Cilang's words.

But as soon as she said that, she immediately realized something, her face turned red and even her neck turned red.

…………………………………

Besides, Wang Chengen went to interrogate Wang Dehua, although he had already given instructions and deliberately kept a low profile. However, it was already night in the palace. No matter how low-key it was, the movement could not be too small.

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

Two eunuchs were lying lanterns and lying lanterns for a eunuch in a big red robe.

As soon as he saw this, the eunuch hurriedly walked over quickly and whispered: "Godfather, it's not good, godfather, something happened!"

When the eunuch heard this, he immediately stopped and looked at the eunuch who had already arrived in front of him and asked, "What's going on with the emperor? What's going on?"

He obviously heard something abnormal on Emperor Chongzhen. Judging from his appearance, he rushed over to see the situation.

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

"What?" The eunuch was shocked when he heard this, "It's dark at night, do you see clearly?"

In fact, in his heart, he knew that such a big thing would never be wrong. However, Wang Dehua, who was the eunuch in charge of the seal and the admiral of the East Factory, said he would take it down as soon as he wanted to take it down. This would make the emperor angry that he would be like this?

"My son doesn't know the specific situation. He just saw Wang Dehua rushing to the emperor. Not long after, he was taken out by Wang Chengen's people."

The eunuch listened for a while, and then immediately asked, "Is it the emperor who summoned him?"

"It seems not, I should have gone to see the movement and then..."

When the eunuch heard this, he immediately turned around and left, and said at the same time: "If you are secretly asking about this, then come to the Imperial Horse Supervision to report it."
