There is one thing that makes Yun endlessly happy.

Her Royal Highness, the princess still needs him occasionally.

For example, ask him to help calculate the weather, whether it will rain or something in the last few days.

Seeing that it was already summer, Tang Guo remembered that at this time of year, there would be drought in the north, and it just so happened that clouds followed the emperor.

She called him, "Guo Shi."

"I don't know what the princess has ordered." Yun Buxi was especially happy to be called by her. As long as she used him, he felt that being a national teacher was not for nothing.

System: Look at the way that pleases, endless clouds, endless clouds, what about the good outsiders? Look at your followers, they all look speechless, don't you care about the image?

"Guo Teacher, please help me calculate whether there will be a drought in the north this year, and what is the rainfall in the south? Will there be floods."

As soon as Tang Guo's words fell, the emperor's face sank.

If there is such an irresistible disaster, the people will not only have enough food, but life problems may also occur.

Especially where there was a flood, it really came as soon as it was said, without warning.

He was happy that Yun endlessly was able to join the Northern Xia Kingdom, just because he liked Yun's endless divination ability.

"Okay, I will divination right away."

Speaking of which, after arriving in the Northern Xia Kingdom, Yun Wuxi has not done divination.

He generally doesn't use divination, and divination is basically a major event. After all, divination is also troublesome.

The matter that Tang Guo asked about now is within his duties, and now he is the national teacher of the Northern Xia Kingdom.

However, even without divination, he has recently faintly felt that the Northern Xia Kingdom, which was originally weakened, seemed to have a feeling of becoming stronger and stronger.

Yun's endless divination is not as complicated as in the legend, but the divination is a major event, so it still takes some time.

After about an hour, Yun Wuxi's expression turned pale.

"Yingzhu, go and pour a cup of tea for the national teacher."

"Yes, Your Highness."

Yun kept opening his eyes, and at the last moment, his frowning brows spread out, with a faint smile on his face.

"The emperor, the princess, there will be no floods in the south this year, but the north will be a bit more droughty."

The emperor was a little surprised, "Since the drought is serious, why does the national teacher laugh out?"

"That's because, even if the drought is severe in the north, there will be no harvest of grains as usual, and people will be hungry and even starve to death."

After speaking, Yun kept looking at Tang Guo with a smile on his face.

It turned out that Beixia's national spirit was functioning well, and it was all her Royal Highness the princess.

However, the mysterious princess, he couldn't tell her origin, he only knew that her luck was pressing, and her body was covered by a thick fog.

Even if he found something abnormal, he still couldn't see through.

The emperor was a clever man. Seeing Yun kept looking at Tang Guo, he asked, "Guo'er, do you have any ideas?"

"Father is wise. In the past few months, my ministers sent people to various places and even other countries to collect the seeds of crops. I wanted to study it first. I didn't expect to discover a treasure by accident. With it, my ministers can guarantee. , The hungry will never reappear."

This baby, of course, is potatoes.

She brought out the potatoes, and there are varieties suitable for various places.

"Where?" The emperor was somewhat surprised.

"When my son discovered the magic of this crop, he sent someone to plant three acres of land. If my father is fine, he can go and see it today."
