Taisun has always been wary of the barbarians and has a deep grudge against the barbarians.

Strictly prevent barbarians from obtaining writing and knowledge from the Central Plains.

Now that the Jin Yiwei is sent to Spain, it is naturally impossible for these killers to negotiate and establish relations with the Spanish monarch, nor can they kill people in Spain.

So what else can these people do if they go to Spain?

Pry into the terrain, power, and national conditions...

Xia Yuanji thought of many things in an instant.

Then, he looked at the emperor's grandson walking in front with ambiguous eyes.

The great grandson of the Emperor has great plans!

It's just thousands of miles away, does the Ming Dynasty really have a chance to reach the land of Europe like it conquered Cochin?

As this idea came to mind, Xia Yuanji could not help but deduce countless possibilities.

A Ming Dynasty with a vast territory far beyond the peak period of the Yuan Dynasty?

Xia Yuanji felt that his internal organs were trembling.

But when such a Ming Dynasty appears, how will people from all over the world be connected?

There are also a series of questions that follow.

Unknowingly, Xia Yuanji felt that his whole head was boiling and it was difficult to suppress it.

The back of his head was throbbing, making Xia Yuanji frown.

At this time, Zhu Yunxi, who had been walking in front, suddenly stopped and turned to look at Xia Yuanji, whose head was twitching.

What's wrong with this guy?

Suppressing the doubts in his heart, Zhu Yunxi smiled and asked: "Brother Wei Zhe, can you do farm work?"

"Huh? Huh?" Xia Yuanji was still thinking about the Ming Dynasty's conquest of Europa at this time. Hearing this, his face was blank. After a while, his face turned red and he said: "I studied when I was young and did farm work in the fields."

Zhu Yunxi smiled and clapped his hands: "In that case, we are relieved."

After finishing speaking, Zhu Yunxi turned around and stepped into a mansion gate.

Xia Yuanji raised his head.

Shanglinyuan Supervisor.

They have actually gone from the riverside pier in the west of the city to the foot of Shenlie Mountain in the east of the city.

Xia Yuanji resisted the deductions and doubts in his mind and entered the Shanglinyuan Prison Yamen with the oak barrel containing sweet potato vines carried by Jin Yiwei.

"I respectfully welcome Your Highness."

By the front lakeside inside Shanglin Yuan Prison, Yuan Sutai no longer wears official robes at all, and even a group of Shanglin Yuan Prison officials wear farmers' clothes to go to the Yamen all day long.

Xia Yuanji was following behind Zhu Yunxi, looking at the group of officials in front of him with doubts and curiosity, who were now members of the Shanglin Garden Supervisor of Tongwu Temple.

Very different from other officials in the court.

This is Xia Yuanji’s first impression.

Zhu Yunxi had already smiled and said: "I got a few new seeds from the Yi merchants today, and I want Yuan Jianzheng and Shanglin Yuanjian to seize the time to cultivate them this year."

Yuan Sutai nodded respectfully like an old farmer: "I will definitely do my best to cultivate new species."

Everyone raised their heads sharply: "But the new species that His Highness offered a reward for a few days ago?"

Zhu Yunxi nodded and waved: "These are peppers. The seeds are all raw. Although it is a little late to plant and cultivate seedlings at this time, it is not too late. I have seen that there are roughly three types, and Shanglin Yuanjian has to plant them separately.

."

Then, Zhu Yunxi pointed to the oak barrel that was carried over.

"This thing is a sweet potato, which can make our Ming people full. It is not suitable to be planted in waterlogged areas, nor can it be planted in clay soil. It should be chosen on soft sandy land with little water. Plant the branched seedlings by cuttings and dilute the agricultural fertilizer.

Nourishing.”

Yuan Sutai's eyes shined as he listened to Zhu Yunxi's introduction.

He repeatedly greeted the officials from the same government behind him: "Take pepper seeds and plant them in the newly cultivated vegetable field by the front lake. Send someone to take care of them, prevent insects, and record the growth every day. This season, we will focus on breeding. Next time

You need to cultivate again every season to distinguish the difference in planting."

Several officials immediately took the old farmer from Shanglinyuan Prison and took away the bag of chili peppers.

Zhu Yunxi did not stop him.

Since the 25th year of Hongwu, Shanglin Yuanjian has made long-term development in cultivating crops. Nowadays, people have begun to try hybrid Shanglin Yuanjian. Simply cultivating peppers is not difficult.

In the end, Yuan Sutai put all his energy and attention on the oak barrel in front of him.

Something to fill your stomach.

Planting by cuttings.

The soil is soft.

Every word Taisun said was engraved in his mind.

In a flash, Yuan Sutai raised his hand and said: "Between Qianhu and Pipa Lake, there is a piece of land with quite soft and dry soil, which is sandy land. The surrounding forest has just been cut down this year, and the light is sufficient. I think it is enough to plant sweet potatoes from cuttings."

When Zhu Yunxi heard that there was such a place in Shanglinyuan Prison, he was still willing to wait.

Who knows how long this bucket of sweet potato vines can continue to produce? According to Fan Chong, there were originally several other buckets of branches and leaves that had withered and the sweet potatoes were rotten.

He didn't dare to stay too long.

Immediately, a group of people went to the sandy land with little water between Qianhu and Bipa Lake.

"First we need to rid the ground and make drainage ditches, and then we can start cuttings."

Looking at the land that had been plowed, Zhu Yunxi gave direct instructions.

Sweet potatoes are really easy to grow.

Even if you have a piece of dry land, prepare it a little, insert the branches and leaves into the soil, and irrigate it with diluted agricultural fertilizer, there will be almost no need to take care of it afterwards.

Yuan Sutai nodded and waved his big hand, which was already covered with soil. Immediately, a group of Shanglin Yuan Supervisor officials wearing farm clothes led a group of old farmers into the field and started to make ridging.

Taking advantage of this opportunity, Yuan Sutai went to the oak barrel again, stretched out his hand to pinch off a branch and leaf, and looked at Zhu Yunxi: "Your Highness, just cut it into the ground like this? Can this thing really make the people of Ming Dynasty full?"

Xia Yuanji, who was on the side, felt something in his heart, and took a few steps forward, wanting to get a closer look at the Superintendent of Shanglinyuan who had reached the third rank.

Zhu Yunxi also walked to the oak barrel and waved to invite Yuan Sutai and Xia Yuanji to come over and share the sweet potato vines.

Several officials from Shanglinyuan Prison immediately came forward diligently and stood aside with a bamboo basket, so that they could wait for the grandson and the supervisor to separate the sweet potato vines and put them into the bamboo basket.

Zhu Yunxi said while dividing the pieces: "Sweet potatoes are the easiest crop to grow, and they do not require soil fertility. And not all the land in the Ming Dynasty was good paddy fields, and there were countless dry lands. In the past, rice was grown.

, wheat production was insufficient, but now sweet potatoes can make up for the poor output of dry land, and the yield is far higher than that of rice!"

"Your Highness, may I ask how much sweet potatoes can be produced per acre?"

Yuan Sutai stopped what he was doing and looked at the emperor's grandson in front of him sincerely.

Zhu Yunxi was stunned for a moment.

I quickly converted the weight in my head.

Once it's about 120 pounds.

What is the yield per mu of sweet potatoes?

Two thousand to three thousand kilograms.

That’s an output of forty or fifty shi per mu.

Just...

"It is estimated that the yield per mu is no less than twenty stones!"

Zhu Yunxi finally gave an extremely satisfying figure for the yield per mu.

After all, the sweet potatoes at this time obviously cannot be compared with those of later generations. The high-yielding sweet potatoes of later generations were cultivated and improved.

However.

The familiar words of twenty stone are spoken.

The entire situation was in an uproar, and then fell into deep silence.

Xia Yuanji opened his mouth. He clearly remembered that when he was in the palace, His Highness Taisun was talking about ten stones per mother. At that time, he and others were extremely disbelieving. Even Prince Yan refuted angrily.

Now His Highness Taisun actually said that the yield of sweet potatoes can reach 20 dan per mu!

Twenty stones!

There was a clang.

Yuan Sutai, the supervisor of Shanglinyuan who had been classified as a third-grade servant, was completely lost and fell to the ground with a crash.
