"The minister knows Zou Yan of the Yin and Yang family, he has a certain study of ghosts and gods, and it is said that he can help himself with the help of the power of ghosts and gods, and the minister can invite him to Zhao Kingdom." Kong said it.

Then, everyone also spoke out one after another, or said that they could invite a hidden elder, or that there was some strange inheritance in the family.

I have to admit that the Spring and Autumn Period and the Warring States Period were indeed a strange and brilliant era.

After thousands of years of development, the aristocracy has reached the limit, and they don't know where the way out is, so they can only grope around for directions, find a place and make a mess, and some families can even knock for hundreds of years.

Only you can't think of it, there's nothing they can't do.

What was studied by someone in the later dynasties, there were people in the Spring and Autumn Period and the Warring States Period. What no one studied in the later dynasties, there were still people studying in the Spring and Autumn Period and the Warring States Period.

Not long ago, Gander and Shi Shen saw the lunar eclipse and suspected that the ground under their feet was a ball, and then they felt that they were a baked cake, how could the ground be a ball, if it was a ball, they would have fallen down a long time ago.

So I just wrote it down in the book and didn't pay attention to it anymore.

Anyway, these two guys found out about this problem in history, and they did the same.

Later, when Yin Gao and Zhao Kuo were chatting, Zhao Kuo was silent for a moment and said, "Is it possible...... The earth beneath your feet is a ball. ”

In the evening of the same day, the two old men found Zhao Kuo.

"The king said that the earth under his feet is a ball, I don't know if there is any basis?" Gander was not polite either, and said directly.

Zhao Kuo was stunned for a moment, and then said: "Standing on the seashore and looking at the ships coming in the distance, I always see the mast first, and then the hull. Ships offshore also always disappear first with the hull and then with the mast. ”

"The old man and his wife have never been to the sea, nor have they ever seen a ship sailing out to sea." Shi Shen shook his head proudly.

"The two of you should climb over the mountain, as the saying goes, the higher you climb, the farther you can see, and if the ground is flat, no matter how high you climb, you should see the same far." Zhao Kuo said.

Gander was silent for a moment, and said: "The earth near the mountain is not flat in the first place, but rises with the mountain, and it is normal to climb high and see far away, which does not mean that the whole earth is spherical. ”

"And if the earth had been spherical, we would have fallen long ago." Shi Shen said.

To be honest, the two old men had long suspected that the earth was a ball, but they had never been able to figure out why they hadn't fallen, and if they could figure it out, they would be able to solve the other problems themselves.

The combat effectiveness of these two old men is still very strong, not only observing the sun's ears, corona, and sunspots. Even Europa and Europa were observed, nearly two millennia earlier than Gali, and the yellow and red angles were measured, albeit with some error.

Now it is not technology, not tools, not even wisdom, but common sense in life.

If the earth were a ball, I would definitely fall, and this kind of thing that is deeply rooted in people's hearts is the most difficult thing to change, not that you explain that the earth is big and we are attracted by gravity.

Zhao Kuo realized that he had caused a big problem, and if he continued to explain this kind of thing, he would pull out a lot of things, and all of them could not be proved by himself.

"The widow also thinks that the earth is a ball based on these things such as solar eclipses. As for how to prove right and wrong, I think it is a matter for the two old gentlemen, not a matter for the widows. What do you think? Zhao Kuo said.

"As for why we didn't fall, have you ever wondered why the rain fell from the sky? Why do people jump and land? Why do bows and arrows land after they are shot? If you can figure out this problem, maybe the first one will be solved. ”

Gander and Shi Shen left.

Since then, Zhao Guo has lost two old men who laugh every day, and two more old men who are frowning and busy.

At this time, Zhao Guo, looking at the rooftop.

"You're still watching." Yin Gao walked up with a basket of red dates and said with a smile.

Gander and Shi Shen didn't reply, and continued to look at the sky with the crystal telescope that had just been polished, this crystal was brought by Zhao Mu from the East China Sea, colorless and spotless, very suitable for lenses, the two old men and the old man of the peasant family stared at the eyeballs for a day before grabbing it.

As for the Mo family and the doctor, they are not embarrassed to rob a group of old men.

Yin Gao was not angry, standing next to him and eating red dates with a smile.

"Aren't you curious?" Seeing that Yin Gao hadn't left for a long time, Shi Shen asked.

"Curious about what?" Yin Gao asked.

"Is the earth a ball after all?" Shi Shen said.

"If you two can solve this problem, I'll know. If you two can't solve it, it's useless for me to be curious, and I can't solve it with my ability anyway. Yin Gao said calmly.

Although he also has a lot of research in astronomy, he has to compare with anyone, and he definitely can't compare with the two old monsters in front of him.

"And what are you doing here?" Gander said angrily.

"Recently, there have been some changes in the sky, and I can't understand it, so I'll ask two guys for advice." Yin Gao handed over the basket, "Jinyang's big red dates, which were just shipped over today, are particularly sweet, try them." ”

"Hasn't the celestial phenomena changed every day in the last two years, what's so strange?" Gander took two large red dates and put them in his mouth, chewed them twice, and nodded, "It's really sweet." ”

"Just now, two never-before-seen stars in the sky brightened up at the same time, and then all the celestial phenomena turned into chaos, and there was no longer any heavenly opportunity." Yin Gao said.

"I'll take a look at the stars I've never seen before." Gander and Shi Shen were a little puzzled, looked at the sky, pinched their fingers with their left hands, and the star map behind them shone brightly, but there was no trace of two stars in the sky for a long time, and the sky was chaotic, as if it was covered by fog, and they couldn't see anything clearly.

"Are you just sure you saw it? Never-before-seen stars? Gander asked.

"I did." Yin Gao nodded.

"I can't see anything now." Gander and Shi Shen glanced at each other, shook their heads, pinched their left hand a few times, but there was no response, and changed to their right hand again, "It's nothing." ”

"If you can't calculate anything, it means that something big must happen." Shi Shen said.

"It doesn't matter, it's not a catastrophe anyway, if it's a catastrophe, it won't be a chaotic phase." Gander waved his hand indifferently and picked up the binoculars, "I just saw that I was disrupted by you, and now I can only re-observe." ”

"Is the celestial phenomenon we saw with this thing the same as the one we just saw?" Yin Gao asked curiously.

"If you use the occupancy method, there is no difference. If you don't use the accounting method, you will only see ordinary stars. "To put it bluntly, this kind of thing is believed to be there, and unbelief is not." If you don't believe in celestial phenomena, no matter how you look at them, they are just ordinary stars. ”
