Faced with Zhao Xu's questioning, Ning Fu smiled confidently.

"This brother mentioned Xixia, so we have to talk about the foundation of a small country, especially like Xixia, which has the Liao Kingdom in the north and the Song Dynasty in the south. It is sandwiched between two big countries. Xixia can survive.

It’s quite difficult.”

Ning Fu paused for a moment when he said this.

"So in addition to its own strength, the most important thing for Xixia is to take care of its relations with Liao and Song. If Liao and Song are evenly matched, then Xixia will not fall to any one country, but if one side is strong...

"

When Ning Fu said this, he glanced at the entire audience, and finally his eyes fell on Zhao Xu.

"If one side is too strong, then Xixia can only act as a lackey of the strong side and constantly provoke the weak side, so as to show the strong side the value of its existence."

The students present here are all smart people, so they naturally understood the meaning of Ning Fu's words, and many of them gritted their teeth secretly for a while.

Zhao Xu's originally sallow face turned red again. As an emperor, Ning Fu's words made him feel ashamed and ashamed.

The Liao Kingdom was powerful, and even if Zhao Xu was reluctant, he had to admit that this was a fact.

That's why Xixia turned to the Liao Kingdom and tried its best to provoke the Song Dynasty. To the Liao Kingdom, Xixia was more like a vicious dog they raised.

Although this vicious dog is occasionally not obedient, as long as the Liao Kingdom maintains a strong position, there is no need to worry about Xixia biting him back.

"I would like to be taught!"

Zhao Xu finally suppressed the anger in his heart towards Liao Kingdom and Xixia, and bowed his hands to Ning Fu.

Ning Fu nodded to Zhao Xu, and then continued to talk about the mountains and rivers geography of the Liao Kingdom.

In fact, Ning Fu could take this opportunity to propose to Zhao Xu a strategy of contacting the Jurchens and attacking Daliao from the north and the south.

Although it was decades earlier, the Jurchens were now in a strong position. As long as the Jurchens raised their troops, even if they could not destroy the Liao Kingdom, they would still be able to deal a heavy blow to the Liao Kingdom.

It can be said that there is no problem with this strategy itself. The key is that the strength of the Song Dynasty is too overwhelming.

From the perspective of the Song Dynasty in history, they contacted the Jurchens to attack the Liao Kingdom, which was a strategy to drive away the wolf and devour the tiger. Unexpectedly, it turned out to be a way to lure the wolf into the house.

Therefore, in Ning Fu's view, the most important problem of the Song Dynasty is actually internal. If it does not enhance its own strength, no matter how clever the diplomatic strategy is, it will be useless.

After talking about the geography of Central Continent, Ning Fu also talked about the customs and customs of several other continents.

On the drawing paper behind Ning Fu, there was a world map drawn, with the locations of each continent marked on it. Although it was not very accurate, the approximate location was still correct.

Finally, Ning Fu talked about the Two Americas, which made him silent for a moment, and then he started to introduce.

"North and South America, I would like to call them a land given by God. The hinterland of North America is full of fertile plains. If cultivated, it would far exceed the cultivated land of the Song Dynasty. As for South America, there are various high-yielding crops, such as corn and potatoes.

The output of sweet potatoes, etc. far exceeds that of wheat and rice.”

Ning Fu paused for a moment when he said this.

"The most important thing is that both North and South America are rich in gold and silver. Some native tribes even use gold to build temples. But what's interesting is that they don't know how to smelt iron. They don't even have metal weapons. They can only use stones to smelt them.

Make various tools.”

Upon hearing Ning Fu's introduction to North and South America, the imperial students below also exclaimed, and everyone showed expressions of disbelief.

Let’s not talk about gold and silver. Fertile land and high-yield food are the foundation of a country. No amount is too much.

"Uncle Qing Ping, since America is so rich, can we send people there by boat?"

A tall and thin imperial student below couldn't help but stand up and asked.

"Theoretically it is possible, but at least you need to organize a fleet and be prepared to drift at sea for several months before you can reach the Americas."

Ning Fu replied.

"A few months!"

"This is too long!"

Other Tai students also exclaimed repeatedly. Although Ning Fu drew a map of the world, they still did not have a very intuitive feeling about the size of the world.

"Everything has been going smoothly for a few months. The sea situation is changing, and no one knows what dangers they will encounter. Maybe a big storm may kill the entire fleet, so if you want to reach the Americas, you need to overcome

Great difficulty.”

Ning Fu explained again.

He didn't know much about the navigation conditions of the Song Dynasty, so he couldn't make an accurate judgment on whether he could reach America.

When the Tai students heard Ning Fu's explanation, most of them showed frustrated expressions.

But there are also a small number of people who have set their sights on North and South America on the map. Although Ning Fu's words are not enough to make these people take practical actions, they still plant a small seed in their hearts.

Maybe one day in the future, when the conditions are right, this seed will take root and sprout, thus bearing a fruit that no one can expect.

Near noon, Ning Fu's lectures came to an end for the time being, and there would be another lecture in the afternoon.

Today, Ning Fu came to Taixue, and after discussing with Li Gefei, he decided to give lectures at Taixue for three consecutive days, giving a general introduction to the geography of the world, so that the Taixue students would have a preliminary understanding of the world.

Although the Tai students who were listening to the lecture were reluctant to leave, they also knew that Ning Fu needed to rest, and it was also time to eat.

So the Tai students left the lecture hall one after another. When there were no outsiders, Ning Fu, Li Gefei and others immediately stepped forward to salute Zhao Xu and Zhang Dun.

"No need to be polite!"

Zhao Xu said and looked at Ning Fu.

"Ning Fu, your performance really surprised me!"

"I am not good at reading, but I have done some research on miscellaneous subjects."

Ning Fu told the truth, but in other people's ears, it sounded like he was being self-effacing.

"Don't be so modest. I asked you to come to Taixue University to study, but it's only been one day. One of you is a good student, and two doctors have recommended you as a doctor. I don't even know what to say?"

Zhao Xu looked at Ning Fu with a smile, and then asked again.

"Are there any classes in the afternoon? How many days do you plan to teach?"

"To inform the officials, there will be classes in the afternoon. Because the Tai students responded strongly, I discussed with Uncle Qing Ping to give lectures for three days in a row."

Li Gefei answered first.

"Very good, leave me a seat in the lecture!"

Zhao Xu immediately ordered.

After lunch, Ning Fu started giving lectures again, and Zhao Xu also came as scheduled.

This time Ning Fu did not talk about new continents, but talked about some neighboring countries and islands outside the Song Dynasty, such as Goryeo, Japan, Nanyang and other places.

Zhao Xu and the students were no strangers to these places, but they did not know them in as much detail as Ning Fu.

For example, Ning Fu explained in detail the current situation of some Japanese countries and the situation of Nanyang mineral deposits, allowing Zhao Xu and others to have a deeper understanding of the surrounding situation.

The entire lecture hall can only accommodate three to four hundred people, so when Ning Fu was lecturing, someone would take quick notes below and pass the notes outside every half an hour.

After the Tai students who were waiting outside got the notes, someone immediately followed the notes and preached loudly, passing on what Ning Fu said to as many people as possible.

Some college students with clever minds even secretly copied their notes and then took them outside to sell them to students in other colleges.

You must know that Taixue represents the highest level of education in the Song Dynasty, so the notes of Taixue doctors’ lectures can also be sold for money.

What's more, the world geography taught by Ning Fu is even more unique and opens everyone's eyes, so there must be many people willing to pay a high price to buy it.

Ning Fu probably wouldn't have thought that he would help others open up a way to make money.

In the next two days, Ning Fu would give lectures on world geography every morning and afternoon, and Zhao Xu also came to the lectures on time.

At the same time, with the spread of Taisheng, the content of world geography spread to various academies in the capital at the fastest speed.

The content of world geography finally caused a strong shock among scholars. Everyone was scrambling to copy Ning Fu’s lecture notes. For a while, the price of pens, inks, paper and inkstones in the entire capital actually increased because of this.
