"Okay." The man nodded incessantly.

The man's performance aroused everyone's curiosity, but everyone couldn't see what he was doing.

"There seem to be a lot of strange things in Jinyan's hands this week." Li Baiyao said suddenly.

Kong Yingda smiled: "It's not just a lot, it's a lot." What is a free chair, a spicy strip, a newspaper....... There's a lot more to do with this kid. ”

Li Baiyao was puzzled: "I don't believe it, the things in his hand can be seen far, far away, and can he still see very clearly?" ”

"Who knows," Kong Yingda stroked his beard and said, "When it's over in a while, take it and take a look." ”

The man held the binoculars and steadied his mind to watch, but he could only see a horizontal plane, and he could see quite clearly. ”

At this time, I don't know who shouted, "Look, the red stick has appeared." ”

The man hurriedly meditated, and sure enough, he saw a wooden stick appear from the horizontal plane, and the end was very strange, and then the wooden stick grew longer and longer, and soon the hull of the ship appeared......

He clearly saw that there was another person on the boat, trying to hold on to the bamboo pole.

Who else could it be if it wasn't Ah Da just now?

"This brother, do you see clearly?"

Zhou Jinyan's voice sounded in his ears.

The man took off the binoculars in a daze, looked at the black dot-like boat in the distance, and couldn't help but rub his eyes.

"This brother?" Zhou Jinyan saw him in a daze, so he had to shout again.

Everyone's eyes also looked at the man at this time.

The man smiled bitterly and said, "You're right, it's true that the wooden stick appeared first, and then the hull appeared, and I can see it clearly." There can be no mistake. ”

After a pause, he raised his binoculars and said, "Zhou Yuma, what is this, why can you see it so clearly from a distance?"

Zhou Jinyan snatched the telescope and said with a smug smile: "Naturally, it's my baby, Xingji put it away." ”

After that, ignoring this person, he said loudly: "The suspicion of this brother just now is obvious to everyone, and now he has also proved what I just said, what else do you have to say?" ”

Before he finished speaking, he saw Wang Liancheng jump up, "I'm not convinced, anyway, I don't think you can prove it in this way." ”

Zhou Jinyan said coldly: "What, are you willing to gamble and be unwilling to lose?" ”

The crowd was silent and didn't know what to say.

What Zhou Jinyan said is indeed reasonable, but for a long time, the round sky has always been regarded as a guideline.

At this time, let them believe that Zhou Jinyan lives on a sphere, and the sky is round and the place is overturned, and the impact of this idea is too great.

Wang Lan said: "Maybe the ground is not flat, but how can you push the sky is not round, how do you prove that we live on a sphere?" ”

Zhou Jinyan said with a smile: "What is not round." There is a cloud of air above us, and at night, can you see the Big Dipper? Do you know how far away he is from us? ”

Wang Lan was silent.

Zhou Jinyan took the globe again.

"We live on it, and above him is the universal sky, so the sky is not round, and there is nothing to prove it. Everyone didn't seem to understand well just now, so let's use another way for you to prove it, and also convince your Wang family. ”

Wang Lan had already lost her previous self-confidence, snorted twice, didn't dare to say anything sideways, and sat down again.

Zhou Jinyan put the globe on the pallet and said loudly: "If the earth is parallel, theoretically we can see infinity, the same principle, if we stand higher, we can see farther, right?" ”

This is clear to everyone, and no one refutes it.

Zhou Jinyan continued: "Suppose we make a tangent line near this spherical surface. ”

He made a gesture simulation and looked at the crowd.

"You see, the farther the point is from the sphere, the farther away it is from the point?"

Zhou Jinyan stood up, "So it can be concluded that 'standing high and seeing far' can show that the earth is round, not the so-called square." ”

This time, Ya Qi was really silent, and everyone looked at him blankly.

Compared to last time, this proof is much simpler.

Zhou Jinyan was very satisfied with the performance of the crowd, and he smiled and said: "This is another self-evident evidence: if you stand taller, you can see farther." If the Earth is flat, you can see the same distance no matter what your altitude is. ”

"For example, the Big Dipper, the moon and the sun we see, they are far, far away from us, so far away that everyone can't catch up in their lives, if you don't believe it, you can ask me, and they will tell you how far away these stars are from us."

"But although they are far away, we can see the same, this distance is far from the distance from the Chang'an city wall to the Yanmen Pass, it stands to reason that we stand on the Chang'an city wall, we should be able to see the Yanmen Pass, but why can't we see it? Do you know why? ”

No one spoke.

Zhou Jinyan smiled, "Because our line of sight is limited to a specific range, the distance is about five kilometers. Why is it restricted? Because we live on this sphere, it is the curvature of the sphere that limits our line of sight to less than 5 kilometers. ”

Zhou Jinyan turned around and pointed to the globe, "It's like Chang'an is here, Yanmen Pass is here, and Yanmen Pass can't be seen at all, unless we can fly, fly very high, and then use such a high-magnification telescope to see clearly." ”

"So, this is already very good proof that we live on a sphere, not the so-called round sky, which is pure nonsense, subjective speculation, and cannot withstand actual beating, nor can we produce evidence."

Wang Liancheng sat on the stone bench and looked at Zhou Jinyan on the stage blankly.

He could never have imagined that he would lose.

Why?

Wang Lan's face was also pale, even if she lost, she would even take another 200,000 yuan, if her family knew about it.......

"Practice brings true knowledge," Zhou Jinyan said with a smile: "Subjective speculation will never stand still, do you have anything that can prove that the sky is round?" Except what you see with your eyes? Can anyone prove it? ”

After saying that, he looked at Wang Liancheng, whose face was ashen.

Wang Liancheng only felt a rush of blood in his mind, and said angrily: "Seeing can't be true, what else can be true?" What I see with my eyes is right. ”

Zhou Jinyan ignored him and said to himself: "The reason why stupid people feel stupid is because they are stupid and don't know it, which is the most annoying." ”

"It's like a knife falling from the sky and hacking a person in front of you to death, and you happen to be standing in front of that person, does it mean that this person was killed by you?"

Zhou Jinyan glanced at Wang Liancheng.

"I... I..."

Wang Liancheng squeaked, and found that he was not Zhou Jinyan's opponent. Take a look at the latest chapter of "Mixed in the Tang Dynasty to be a Horse Claw Book House" to read for free for the first time.
