Daming: I became Zhu Yuanzhang's eldest son

Zhu Tao sighed, and he said to Zhu Yuanzhang.

"I said Dad, making this kind of sand table is very labor-intensive. Even if I don't eat or sleep, it will take at least a month. Besides, I can't do it without eating or sleeping,"

Zhu Yuanzhang is very clear about Zhu Tao's personality. Let alone making him work overtime, this guy struggles to get him out of bed.

"Then what do you think should be done? The imperial court lacks sea charts about Dongpu. You can't do anything about it, right?"

Now that Zhu Yuanzhang said so, Zhu Tao thought about it carefully before answering.

"There are ways, but if I can figure out a way, you have to let me go back to sleep, and it's the kind that sleeps for three days directly, don't let the third brother call me."

After hearing Zhu Tao's words, Zhu Yuanzhang's face was covered with black lines. This bastard would really take the opportunity to raise conditions.

"Okay, then as you said, we promise you to tell your solution, but this is a major court matter, so don't laugh and laugh."

Zhu Tao nodded with a smile before speaking.

"I have a sphere at home now, on which is a map of the entire world. All countries including Daming are all on that sphere. Please send someone to bring it over."

Zhu Yuanzhang immediately ordered the captain on duty to say.

"Take someone to Zhujiazhuang immediately, and bring us the ball. You go there on a royal horse, and you will be back within half an hour at most!"

After the school lieutenant heard the order, he quickly agreed, and then hurried down to make arrangements.

Zhu Tao also wanted to leave, so he told Zhu Yuanzhang.

"I think if he goes by himself, he may not be able to find it soon. I will help him find it, because I don't know where to throw it."

But before turning around to leave, Zhu Yuanzhang grabbed his ear and said something.

"It's not over yet, you kid, don't try to slip away, just stay here honestly, if your map really works, we'll give you three days off."

In desperation, Zhu Tao had no choice but to stop the captain and tell him the exact location.

Sure enough, within half an hour, the school lieutenant had returned, and all the officials focused their attention on him.

Zhu Yuanzhang also couldn't wait to ask: "How is it? Did you get the things back?"

The school lieutenant put the ball on the table, including Zhu Yuanzhang, the faces of everyone present became a little strange.

At this time, what everyone sees is a blue ball with a base underneath, and various text information and texture patterns are marked on the ball.

This is a globe made by Zhu Tao himself. This thing is almost a standard equipment for primary and middle school students in later generations, so it is not surprising.

But for the officials of Ming Dynasty, of course they looked confused. After all, they didn't have that kind of knowledge reserve, so it was natural for them to be difficult to understand.

When Zhu Yuanzhang saw everyone like this, he was naturally puzzled, so he said to Zhu Tao.

"Tao'er, don't be a fool anymore, take out the things quickly, everyone has been waiting for a long time."

Zhu Tao looked helpless, and he replied directly.

"Father, you let someone go and put the things you brought back here, but you turned a blind eye. This is the map of the whole world."

Everyone present was even more confused. After all, in their eyes, it was just a round ball. How could it be a map?

Zhu Yuanzhang also widened his eyes, as if he couldn't bear it anymore, he said in a scolding tone.

"You boy, isn't this just teasing your father with all the courtiers? What kind of map is this!"

Zhu Tao looked serious, he wasn't joking at all, and he was going to give everyone some knowledge.

"I'm not kidding, listen to me slowly, this thing is a map, but it is a map of the world, which is to scale down all the nine states and nations in the world."

Zhu Yuanzhang was taken aback again, he looked at Zhu Tao with some puzzlement and asked.

"According to what you said, wouldn't the world be a ball?"

Zhu Tao nodded. He felt that it was no wonder that his father was able to become the emperor. His brain was really quicker than others, and he was able to accept new knowledge so quickly.

"That's right, the earth is round, so there's nothing wrong with saying it's a ball."

After hearing Zhu Tao's words, Zhu Yuanzhang was about to be laughed out of anger. This is serious nonsense.

If someone else said this, I'm afraid I wouldn't even refute it, so I just pulled it out to beat the board, but since my son said that, he can only debate.

"Tao'er, when will you be able to be reliable? If you can't prove what you said, dad will punish you slightly."

Zhu Tao came and said with a smile and interest.

"Then let me give you an example. You send a person or a group of people to walk in the same direction. If the direction does not deviate, it will take about twenty years to reach the origin."

Zhu Yuanzhang has a black line on his face. Don't talk about how to verify this question. It took more than [-] years to prove this point. Do you think Lao Tzu is mentally ill or what?
"Can't you give some practical examples?"

Seeing his father was a little unhappy, Zhu Tao stopped going around in circles.

"To put it simply, if we board a hot air balloon and rise high enough, we will find that the arc of the horizon is curved, which means that the earth is round, and this hot air balloon is probably the same principle as the Kongming Lantern. Later, I invented One for you to see."

Before Zhu Yuanzhang recovered, Zhu Tao continued.

"In the same way, if we stand very high, we can see more scenery than people on the ground, because the world is round, and people standing on a high place can see more distant scenery , if the sky is really round, then these things would be impossible.”

The example Zhu Tao gave can be regarded as easy to understand, and all the ministers present were taken aback.

Although they did not accept the scientific knowledge, they were fully able to accept such an interpretation, which sounded reasonable.

At this time, seeing that everyone still had some doubts, Zhu Tao said.

"If you still don't believe that the globe is correct, send an envoy to Dongpu to have a look, and then you will know that I will not joke when it comes to national affairs."

Seeing Zhu Tao's appearance, both Zhu Yuanzhang and the Liubu Jiuqing present understood that Zhu Tao was serious.

Zhu Yuanzhang took this globe to study for a long time, and became a little depressed again.

"Tao'er, according to this globe, there are so many countries in the world. Besides Daming, there are hundreds of other countries?"
