Shangguan Wan'er said with a smile: "The old man is not lazy. He doesn't rest until late at night every day. But after all, I am getting older and I am a little too lazy to get up in the morning."

Jiang Fan looked at her: "It seems that you and the old man get along well."

Shangguan Wan'er said: "Wan'er is young, and the old man was no longer there when he entered bliss, but after all, they are from the same place, so they are naturally closer."

Jiang Fan nodded: "Although the old man was born as a shadow guard, he loves astronomy and is an extraordinary person."

Shangguan Wan'er said: "As a scholar of heaven and earth, Wan'er takes advantage of the opportunity to listen to the teachings."

"Are you interested in these?"

"It's very interesting. There is so much knowledge in the stars in the sky. Wan'er has never paid attention to it before."

"Then you have to be careful. The old man is not an ordinary cow. Let me tell you the truth. Even after a thousand years, everything about the old man will be famous in history, and will even lay the foundation for the theory of astronomy. He has some knowledge, and future generations will use all their methods.

It may not be possible to achieve his accuracy."

Shangguan Wan'er couldn't help but feel moved in her heart. This master was a true scholar. Even Old Xingjun was amazed. Now that he is praising Old Xingjun so much, is this knowledge really so amazing?

For a moment, Shangguan Wan'er felt a little itchy.

Since he didn't go to court anyway, Jiang Fan was not in a hurry to go back. After breakfast, he had half a day to spare and planned to continue fishing at the lake.

But quietness is still rare. Before I can sit still, I am disturbed by others.

Dragon Si came to report that there was a strange person asking to see him.

wack?

Long Si frowned and said, "Unlike the Chinese, the eyes are blue... I said it was a gift for the prince."

Jiang Fan's heart moved and he dropped the fishing rod: "Haha, they came very quickly... Let them come in and arrange to wait in the main hall."

After Long Si left, Jiang Fan couldn't help but get excited.

He didn't care about the foreigners, but they represented ships, especially new crops. This was the reason why Jiang Fan couldn't control himself.

Instead of going to the main hall immediately, Jiang Fan went down to the dungeon first.

To my surprise, I found that Lin Nanyan was also there. This time, he was not fighting against the landlord. The two of them had their heads together, staring at a drawing spread out on the ground and chattering, not knowing what they were discussing.

Jiang Fan stepped forward and took a look, and it turned out to be a nautical chart.

Lin Nanyan was making gestures and said: "This is wrong. My young master once said that this is an unknown continent. He calls it Africa. When coming from the east of your continent, you should take this corner. How did you go around so far?"

Hathaway said: "This is also the first time for us to explore such a distant sea. There is no detailed chart. We drew this one ourselves. But I don't believe what your young master said is right. He is so young, how has he ever been to the sea...

"

"You don't understand. The young master knows astronomy and geography. There is nothing he doesn't understand. This route is definitely far away, as far as grandma's house..."

He was actually studying a nautical chart? Jiang Fan couldn't help but be surprised.

The map in front of him can only be described as extremely rough, and the entire world does not have a clear outline. The only thing Jiang Fan is not sure about is whether the pattern of this world is roughly the same as his own, so it is difficult to

Evaluate right or wrong.

Neither of them noticed Jiang Fan arriving quietly, and they kept gesticulating and discussing.

Jiang Fan had no choice but to cough and remind the two of them.

Only then did they realize that Jiang Fan had come in, and Lin Nanyan jumped up quickly: "Master, why are you here? Come and see if something is wrong with this..."

Hathaway frowned, but she was immersed in the discussion and did not pay much attention to her identity. She argued: "This is how we came all the way. The sea is not as imagined. We can only explore and move forward. She said you

If you know the correct route, come and see..."

Jiang Fan lowered his head and looked at it: "Is this your chart?"

Hathaway shook his head: "No, I drew this myself from memory, and Wang also has a copy."

"You still understand this?" Jiang Fan asked in surprise.

Hathaway was proud: "I have been yearning for the sea since I was a child. I am best at identifying directions on the sea. Most of our sailing depends on me!"

Jiang Fan was amazed that this woman could do it. While groping forward on the endless sea, she could also draw sea charts and even accurately identify directions. She was an extraordinary person.

Suddenly, Jiang Fan actually didn't want to let her go.

It's a pity that the matter of food crops is ten thousand times more important than her right now.

"This chart of yours is too rough. It's not easy for you to survive based on this."

Jiang Fan shook his head.

Hathaway was unconvinced: "We already have the most detailed nautical charts in the world. There is no way anyone can do better than ours."

Jiang Fan laughed contemptuously, "A frog in a well!"

Hathaway said angrily: "On this continent, you may know more than us, but in the boundless sea, you will find how ignorant you are!"

Jiang Fan suddenly felt something in his heart: "In that case, come with me and let you learn a lot!"

Soon, Hathaway was so shocked that she felt dizzy.

However, the other party only let her take a look and put it away.

It is an unparalleled map of the world. Not only is the drawing incredibly detailed, but the densely packed location marks are so numerous that it is simply unbelievable.

What she couldn't accept the most was that if all this was true, would the world be a round ball?

Hathaway said blankly: "This can't be true... How can there be such a detailed sea map in the world? You are lying to me. This is a random drawing..."

Jiang Fan sneered: "Don't think I didn't notice it. You should pay attention to the location of your own country at the first time. It's always right, right?"

Hathaway looked extremely confused. Indeed, when Jiang Fan showed this unparalleled grand drawing, her first reaction was that it was absolutely impossible. Then she quickly scanned the location of her country. However, she was surprised to find that the outline was roughly

Not bad!

This was what shocked her completely. If everything was correct, the rest...could it really be true?

And her shocked expression at least convinced Jiang Fan that some places should be good. According to what he saw, many mountains, rivers and rivers in this world are different from before, but they are almost the same in general outline. Hathaway's performance further proved that,

This may also be true in distant worlds.

He rolled up the drawing and threw it to the triumphant Lin Nanyan. He looked at the lost Hathaway: "Do you think that's it? I'll ask you two simple questions. Can you answer me?"

Hathaway looked at Jiang Fan subconsciously.

"You may answer, why can the mast be seen first from the distant sea, and then the hull can be gradually seen?"

"That's normal..."

Suddenly, Hathaway stayed on the spot. Before she finished speaking, she realized something was wrong.

Yes, why? Isn’t the sea flat? Why do you see the tip first and then the bottom?

She had not noticed this for a long time, but she had never considered why.

And when the other party asked, she realized that this simple phenomenon seemed extremely extraordinary.

"Second question..."
