Accompanying Princess Jinyang to the beach to see the sea every day is really not a way! Li Zhonghua asked people to drive a big boat out to sea early in the morning and wait until the afternoon to return.

Let Princess Jinyang see as soon as possible that when the big ship appears from the sea level, whether she sees the sails first or the whole ship at the same time, so that she has no reason to pester herself every day to accompany her to the beach to see the sea.

Although Jinzhou is close to the sea, there are not many fishermen who make a living by going out to sea to fish, and they mainly use small fishing boats to fish near the sea, and they will not run very far.

In this era, there are already many fish near the seaside, so why bother to go far?

Moreover, in this era, fishermen used small wooden boats to enter the deep sea, but they could not withstand the wind and waves in the sea.

And a small wooden boat, where there are any sails, it is not clear to see, whether the sails are seen first, or the whole ship.

In order to achieve Princess Jinyang's wish as soon as possible, Li Zhonghua could only let people go to sea on a big warship, turn around and come back.

The weather on the second day was very good, cloudless, the sea was very calm, there was no big wind and waves, suitable for long-distance sailing, and the sight was also very good.

Standing on the seashore, looking into the distance, you can clearly see the horizon in the distance, when a black shadow suddenly appeared on the horizon, Princess Jinyang was excited like a child, jumped up and pointed to the sea level in the distance, and the black shadow that came out said loudly: "Look, on the sea in the distance, there is a boat coming." ”

"Look closely, see if you see the sails first, or if you see the whole boat." Li Zhonghua did not remind in surprise.

This play was originally directed and acted by him, so what is there to be surprised about, as long as Princess Jinyang is happy, she doesn't have to pester herself in the future, and she will accompany her to watch the sea together, and it is enough to achieve this purpose.

"Sure enough, I saw the sails appear first, and then I saw the whole boat, maybe your conjecture is right, the land we live in is round." Princess Jinyang said with certainty.

"The minister's conjecture is originally right, what is called may be right." Li Zhonghua pretended to be dissatisfied and said.

"This can explain clearly, the reason why there is day and night is also because the world we live in is a spherical object." Princess Jinyang ignored Li Zhonghua's dissatisfaction and continued.

"This spherical object rotates every day, and it revolves around the sun, so the sun comes out in the morning, the sun shines directly at noon, the sun goes down again at night, and then it is night.

Princess Ben was conjecturing that if the place where we live is really a spherical object, and it rotates every day, then the place where we live on the other half of the sphere at night must be the place where the sun can shine.

And we are here now, and the place on the half sphere should be night, do you think that the princess is reasonable? Princess Jinyang said with a very smug smile.

Li Zhonghua was very surprised in his heart, Princess Jinyang was able to speculate so many things from the fact that the earth is round, and the speculation was very correct, it was really hard to believe, this is a girl living in the Tang Dynasty, and she is also a princess.

It is not an exaggeration to describe Princess Jinyang as a genius girl!

If you meet a famous teacher in the later life, and you will be carefully trained, you may become a very good astronomer, or even a physicist.

"Your speculation is very plausible, and it should be correct." Li Zhonghua said with full affirmation.

"If one day, we can go to the other half of this world, then we can be sure whether this conjecture is right or wrong, and what kind of world will it be on the other side of the sea?"

Princess Jinyang looked at the end of the sea, and suddenly quieted down, as if she was quietly reverie, what should the other side of the sea be like?

"If the world were a spherical object and you were asked to pick a name, what would you call it?" Li Zhonghua's heart suddenly moved, and he couldn't help asking.

"Since it's a spherical object, it should be called Earth, and we'll call it Earth in the future, how about that name?" Princess Jinyang blurted out without thinking.

"Good! You are the princess of the Tang Dynasty, since you named him Earth, then we will call it Earth from now on. Li Zhonghua smiled slightly and said with some doting.

In Li Zhonghua's heart, Princess Jinyang is like a younger sister of his, the kind that has nothing to do with the love between men and women.

In later life, his parents only have one son and no brothers and sisters, and he has always hoped to have a well-behaved and sensible little sister, and Princess Jinyang completely fits the image of the sister in Li Zhonghua's heart.

"On the other side of the earth, in fact, there is nothing special, the same mountains and rivers, the same sunrise and sunset, the same experience of spring, summer, autumn and winter, day and night.

The difference is that the people who live there, they are basically blonde and blue-eyed, with white skin, but there are also black people, such as Kunlunnu, who are trafficked by some merchants from the Western Regions from the other side of the world.

There is an empire called the Great Eclipse, which is expanding wildly, and their land area has crossed from one side of the earth to the other.

There are still many places on the earth, there are only a very small number of primitive tribes, living in the primeval forest, living a life of hunting, they have no writing, only a very local language, today we go to meet, can not communicate normally.

They don't know the value of gold and silver, so they don't have a sense of money, they only care about food, and if you bring the food they need, you can get a lot of gold and silver from them, but you have to have it in their hands.

They wore no clothes, and at most they used large leaves or animal skins, which were tied to their bodies to cover their ....... Li Zhonghua became interested for a while, so he talked about the general situation of Europe and America at this time.

Although I dare not say, what is it like to understand the life of Europeans? But it's very messy, that's for sure.

Britain was often invaded by the Danes, and the population of villages and towns, was massacred and enslaved.

Germany and France had just separated, and their strength was still very weak, and plague and human diseases were rampant, and this period was called the darkest period by Europeans.

The Arabs defeated the Persian Empire and occupied all of its lands, establishing a powerful empire across Asia, Africa, and Europe, which would directly threaten the security of the Tang Dynasty in the future

There was also the Eastern Roman Empire, which was still strong, and after the fall of Western Rome, it entered a dark age of chaos.

In the primitive forests of the Americas, the current situation of the Indians should still be similar to the primitive era!

"These places are really messy, and the people who live here must be very pitiful! Why can't they have a unified dynasty like our Tang Dynasty, wouldn't that be great? Princess Jinyang said compassionately.
