The firing of cement is a long and boring process, and Lin Chuan naturally will not wait.

During this time, it can just be used to teach Cao Jie a lesson.

Lin Chuan had already thought about it, anyway, he was idle, so it was better to instill modern knowledge into Cao Jie little by little.

Cao Jie is Cao Cao's daughter after all, if she wants to do something and change something, she will definitely not be as tired as herself.

After all, the name of the family is here.

Moreover, Boss Cao is an informal person, and he never thinks about the inferiority of men and women and heavy etiquette.

These things, in the eyes of Boss Cao, are all dross.

Since Lin Chuan taught Cao Jie, Cao Jie naturally no longer called Lin Chuan a young man, but called him sir.

In ancient times, sir was definitely an honorific title.

belongs to the existence of Confucianism, and the status of Mr. Teaching has always been very high.

For example, the Pope's husband, even if the prince ascends the throne, he is polite to the teacher.

There are really a lot of gentlemen who have become Taishi in history.

"Sir, what are we going to study today?"

Cao Jie looked at Lin Chuan with a blank eye.

Lin Chuan smiled:

"History is finished for you, but in fact, these are not very useful, just to let you understand how many mistakes have been made in history."

"In the future, we must pay attention to these things and avoid them."

"What I'm going to talk to you about today is geography."

"Geography?"

Cao Jie looked at Lin Chuan with a dull expression:

"Is it farming? I know this, is there a unique way for Mr. to govern the land? ”

Lin Chuan smiled bitterly and said:

"What farming? Geography is geography, to put it bluntly, it tells you how big the world is, where there are people, and what culture is. ”

Seeing that Cao Jie still didn't understand much, Lin Chuan simply exchanged a world map Three Kingdoms version from the system mall.

There is still a big gap between the map of the Three Kingdoms version and the modern world map.

At the very least, there are not so many countries.

In addition to the Kushan Empire, Rome also had Egypt, Persia, etc., and the rest were almost all primitive tribes, and some even lived in primitive societies.

This is not an exaggeration at all.

China, ancient Rome, ancient Egypt, ancient Babylon, these are all ancient civilizations.

There are many uncivilized and civilized peoples.

How long has the history of the United States?

But China has a history of 5,000 years.

Looking at the huge map, Cao Jie was suddenly extremely shocked:

"Sir, why is this map different from the map that Jie'er has seen since childhood?"

Lin Chuan carefully taught:

"What you saw before is just a map of China, only the land of Kyushu and the surrounding alien races."

"You know, it's a big world out there."

"Let's just say that the closest to the land of Kyushu is this Kushan Empire."

"The Kushan Empire, in later generations, was also known as the Asan Empire, and this country was extremely strong in the late Eastern Han Dynasty."

"His strength is no less than that of the land of Kyushu, and even surpasses the Central Plains in some aspects."

Hearing Lin Chuan's words, Cao Jie's worldview was directly subverted.

What?

In addition to the Han Dynasty, there was such a powerful country?

Shock was shock, but Cao Jie quickly accepted it.

In fact, a long time ago, Cao Jie felt that the world must be far bigger than the land of Kyushu.

For example, when the Silk Road was in the past, a lot of new worlds had been discovered, and a lot of good things were brought back.

This is enough to show that there are other extremely powerful countries in the world.

Of course, Cao Jie thought that only the West had it, but he didn't expect that there would be such a big country in the south.

"Sir, where is the land of Kyushu?"

Cao Jie asked curiously.

Lin Chuan pointed to the map and said indifferently:

"The red areas are all over the place."

Cao Jie was suddenly shocked:

"I didn't expect that the land of Kyushu was only so small......"

Originally, Cao Jie thought that the land of Kyushu was big enough, but now it seems that there are many places larger than the land of Kyushu.

Lin Chuan smiled:

"It's not big, it's not big, but the civilization bred in the land of Kyushu is too far ahead of other places."

"Don't look at these gray areas so big, but most of them are not inhabited, and many places are still primitive societies, living a life of wool and blood."

Cao Jie nodded weakly, and then continued:

"Sir, where is this blue area?"

"That's the ocean, and the ocean is much bigger than the land, and about seventy percent of the world is the ocean."

Lin Chuan explained unhurriedly.

"The sea!"

Cao Jie's eyes suddenly lit up:

"If only one day I could go to the beach."

Speaking of which, Cao Jie has never been to the beach, nor has he ever seen the sea.

It's not that there is no sea in the north, but that Cao Jie can't get out at all.

Even Cao Cao, who wrote about watching the sea, has never seen the sea a few times.

After all, there was only one mysterious impression of the sea in ancient times.

During the Three Kingdoms period, there was not so much technology to make ships that could cross the oceans.

Sun Quan discovered Yizhou Island, but the distance between Jiaozhou and Yizhou is not long, and if it is farther, it will not be able to pass at all.

A little more advanced is the neon country in ancient times, which was called Yamatai country during the Three Kingdoms period.

At that time, the king of the Yamatai Kingdom, Himiko, had visited the Han Dynasty and learned a lot of advanced knowledge.

At that time, the neon country had just been able to eat rice, and I don't know how many years behind the Chinese civilization.

That's basically the farthest you can travel in the ocean right now.

"Someday, I'll take you."

Lin Chuan said with a smile, and then shook his head self-deprecatingly.

If you can go out, you will definitely see the sea.

Hayashi Chuan has mastered modern technology, and it is not difficult to make a ship that can cross the ocean.

But now the difficulty is how to get out of this island.

Cao Jie saw Lin Chuan's thoughts and said with a smile:

"Don't worry, sir, I'm sure my father will find a way to help him overcome the fog."

"One day, Sir will definitely not be trapped on this island, and you can see the scenery outside."

Lin Chuan just smiled indifferently.

It's easy to say, but no matter how powerful Boss Cao is, he can't solve the fog.

Still, there is hope.

After all, the fog was getting thinner and thinner now, much thinner than when Lin Chuan came five years ago.

The biggest change is that Lin Chuan can now see the sun through the fog.

If that is the case, maybe one day the fog will actually lift.

However, I just don't know what time it is.

Just as Lin Chuan sighed.

Suddenly, a cold mechanical voice appeared in Lin Chuan's mind:

"Ding, congratulations to the host for teaching the beast to learn the stirring action and gain a lot of experience in beast mastery!"

"Ding, congratulations to the host! Beast Mastery Beginner has been upgraded to Beast Mastery Intermediate! ”
