Just thinking about it out of thin air, to be honest, is indeed a bit unimaginable.

Still, just take an apple.

This is also one of the benefits of the Academy of Sciences, in addition to eating meat every day, from time to time, you can also replenish some fresh fruit.

However......

Even so, Li Chong's model is just one of the models that is unlikely to be accepted by the world.

"I suddenly remembered! One more thing is that it can be proved that the ground under our feet is actually a ball. ”

“……”

Everyone looked at him silently.

That is, why the moon on the fifteenth is the roundest, while the moon at other times is generally gnawed on a piece. There is also a lunar eclipse, which must be blocked by something. ”

"Actually, the thing that stands in the way is the land under our feet."

Although this idea is relatively bold and forward-looking, but!

But it was surprisingly easy to understand, and the mouth suddenly opened.

"But if it's round, why can't we feel it at all, and if it's round......"

Someone said again.

"Because the ball is so big, so big that we can't feel it at all. I know what you're trying to say, like, why we don't fall. Then when you ride a horse, the horse runs so fast, why don't you fly out. It's because you're used to riding on a horse, you use the horse as a reference, and you and the horse are stationary. If the horse can do the same movement, and you can't find anything else to refer to, you will naturally think that the horse's back under your ass has never changed, and will never change, and that it will not be affected in the slightest if you move your ass on it. ”

Although this is a bit abstract, Li Chunfeng seems to have vaguely grasped something.

It can only be said that such an idea is too nonsense.

It's all up to Mr. Li's own imagination.

But......

Perhaps, he can really start with the profit and loss of the moon and the lunar eclipse.

"Mr. Li's idea is amazing, and I can't be wrong. I just don't know where Mr. Li learned it? ”

"Uh...... When I was a kid, I loved to look at the moon. ”

Then Li Chong said.

Make it up, just make it up.

"Actually, there is a way to do it now, and you can see that the moon itself is a ball, not a pie."

Next, Li Chong made a telescope for Li Er.

Moreover, it was said that the moon was a ball as long as you could use a telescope.

That day.

Li Chunfeng pulled Li Zheng to find Li Er to ask for the telescope.

Fortunately, Li Er didn't give it to others, he originally wanted to give it to the scouts in the army, but the question is, there is only one, what is the use.

There are hundreds or thousands of scouts in the army, and it is difficult for anyone.

Thereupon......

After accompanying Empress Changsun to see the moon, he temporarily put it at Empress Changsun's place and played with Empress Changsun as a toy.

Li Er could think of it again, and the things that were sent out could actually be returned.

So he ordered someone to tell the queen to get the telescope back.

Fortunately, Empress Changsun heard that this thing was important, and she didn't let Li Lizhi and Li Tai play with them, otherwise, if nothing else, it should have fallen into Li Tai's hands by now.

At last......

I had to trouble Empress Changsun to bring someone back the telescope in person.

Li Chong also saluted with his hands crossed, promising to make a better one for the queen next time, and then he gave up.

As soon as Li Chunfeng heard that Li Chong could still do it, he asked, "Then why didn't you say it earlier?" ”

Li Chong replied: "The key ...... You didn't ask me. ”

“……”

"Forget it! Don't all come back. If you don't know the recipe for glass firing, there are more or less such things. ”

That night.

Li Chunfeng stayed at the Academy of Sciences to watch the moon.

Originally, Li Chunfeng thought that Li Chong would be like him, full of yearning for unknown things.

Outcome......

Li Zhong left him here and went home by himself.

After all, what is so beautiful about the moon in this sky, you have to look at something big, round and white, and you have it on your concubine.

And, more aesthetically.

Watched it all night.

Li Chunfeng also had to convince Li Chong that it was more likely that the moon was indeed a ball.

Instead of what someone at the Academy of Sciences said before, it's a pie.

But is the ground under their feet also a circle?

Truth be told, this is still up for debate.

It can only be said that this person of Master Li is really amazing, and there seems to be nothing in this world that he can't intervene.

Anyone who accepts something new will inevitably need a period of adaptation.

Not to mention, this model is so simple and complex at the same time.

In fact......

In Li Chunfeng's own opinion, every point that Master Li said sounded correct.

It's just that......

No one can prove why this is true.

But one thing is for sure, this set of models can indeed explain the day and night, and even spring, summer, autumn and winter, and even problems such as the waxing and waning of the moon and the eclipse of the moon.

It's like you think that what he says is unreasonable every step of the way.

But when put together, it makes perfect sense.

Why, you ask?

He couldn't answer that Bachelor Li, because this world might be like that.

If other people heard it, they didn't know how horrifying it would be.

Early the next morning.

Li Chunfeng also had to go back to the Taishi Bureau to be on duty, so he also asked someone from the Academy of Sciences to leave a sentence for him and ask Bachelor Li what this model is called.

Li Chong came very late, and also replied: "This thing, let's call it heliocentric." ”

After that, it is time to deal with the day-to-day affairs of the Academy.

For example, the one who said that he invented the flying machine, this will not kill you. This thing doesn't look sturdy enough.

Subsequently......

Li Chong looked at the sachet made by one of them again.

This one is a bit like that!

Much like the sachet he once saw online.

Of course, the workmanship in front of me is a little worse now.

But then again, it doesn't feel like a problem to hang such a big sachet ball on the side of your thigh.

After checking their results.

After that, Li Chong made a puff boat with his own hands, so that they could gain knowledge.

This is the simplest 'steam engine'.

Everyone admired the dean so much.

And then!

I've seen it too!

It was also time for Li Chong to announce that next, they were going to make a steam locomotive.

Although this thing is very difficult, you can't do it in 3578 years, maybe even 10 or 20 years, but if you don't do it, you will never be able to do it.

Fortunately, he loved to 'learn' before he crossed, and he saw a small steam train made of hardcore up on station B.

Honestly, that guy is doing really awesome.

He's still kept, huh...... It's about five percent memory.

But that's enough.

At least not zero percent.

Everyone was shocked by the dean's astonishing plan. Do you want to travel thousands of miles a day, do you want to go from Chang'an to Luoyang in just one or two days? And transport a million quintals of grain at once?

Now, let them do the impossible.

Of course!

One thing must be stated! It's definitely a long and difficult task. During this period, it is inevitable to face many difficulties.

But as long as they persist and don't give up, anything is possible.

inspired them, in fact, Li Chong also clearly knew that even if he researched it, there would not be so much iron to build a railway.

Unless, gather all the people of the Tang Dynasty to smelt iron together.

But when the time comes, the people may not be able to live so nourishingly.

The Great Wall of the Qin Dynasty and the Grand Canal of the Sui Dynasty are all vivid examples in front of us.
