Datang.

Xiu De Fang.

Li Chong went to Li Er early this morning to ask for his 'Lamborghini' back.

This 'Lamborghini' is different, the whole body is red, the limbs are strong and powerful, and at first glance it is a good horse that can travel thousands of miles a day.

Of course!

What's more, only such a horse can bring out its handsome temperament.

"Dean, you're back."

"Hmm!"

And, behind Li Chong, there was also a person with him.

However, his horse is much worse than Li Chong's, no, fortunately, he also knows the road.

"Master Li, you're riding too fast, you're waiting for me."

Actually, Li Chong didn't want to.

"This horse is the first time I have ridden, and I can't control it a little, but before I know it, it's fast."

The person who came was Li Chunfeng.

Because Li Chong wanted him to help do one thing.

This is not!

Since the Academy of Sciences completed the development of the pedal reel, the pedal threshing machine, and in fact, the curved plow, Li Chong thought about what they would do next.

I can't think of a good idea.

But you can't let them stop.

On the one hand, he let them play freely, and on the other hand, he was planning to do something next time.

In fact......

Li Chong has always wanted to make a model of the operation of the universe.

Of course, to say that the universe is big, to be precise, it is better to say that it is a model of the movement of the planets and the moon in the solar system.

It's the kind that is driven by gears, and then the hand handle rotates at the same time, and the planets also rotate.

It can be said that ......

This should be a kind of toy for him.

It's a pity that he doesn't know much about the orbital cycle of this planet, and he must know about the earth, but what about other gold, wood, water, fire and earth. Even, there is Uranus, Neptune.

Of course, Uranus and Neptune are too far away to be observed with the naked eye.

But gold, wood, water, fire, and earth can basically be seen.

Among them, Mercury has been recorded many times in ancient classics, saying that the transit of Mercury must indicate something.

Li Chong didn't know Li Chunfeng before, so he was embarrassed to ask the other party for help.

Right now......

Acquaintance, that's just right, give me here to work overtime!

After talking to Li Er, he brought Li Chunfeng with him.

A petty official like Li Chunfeng of the Taishi Bureau has a large amount of astronomical observation data in his hands, and if he can have his observation data as a reference, this toy may be able to make it.

"Master Li, what do you want me to help you with?"

As soon as the words fell.

Li Chunfeng saw the plaque in front of the Academy of Sciences, 'The People, the Source of the Country'.

Suddenly, admiration for Li Chong arose.

"The people are the source of the country."

"This should be written by yourself, Master Li, right?"

I saw Li Zhong pointing to the guard on duty at the door and said, "No! He wrote! ”

The guard's face flushed.

"I said it, and then let him write it, and finally hung it up."

"Oh, I see, but it's pretty much the same." Li Chunfeng didn't care and said, "I've heard about Chengnan a long time ago. It is said that the Academy of Sciences has made some things suitable for relieving women's labor, and they are made quite skillfully, and they are all good things for the people. These words are very appropriately written. ”

Li Chong said: "Don't flatter me, hurry up and go in." ”

"Dean."

"Dean."

The oncoming people greeted each other.

"Dean, you're finally here, Dean, take a look at this flying machine I made."

"You don't call it a flying machine, you call it a foreign country, why are there so few people, and finally found the reason."

"What do you mean?"

The other party looked puzzled.

"Call everyone here and have a meeting."

Li Chunfeng can also see that this is simply a small invention workshop.

There are all kinds of gadgets in it, and there are so many.

During the period when Li Chong ignored them, they obviously also exchanged their invention experience with each other, so they looked at a lot of useless things.

After everyone has arrived.

Li Chong began the meeting.

didn't say that I should be loyal to the Tang Dynasty and His Majesty, so I said directly: "Next, I want to make a gadget that can simulate the trajectory of the sun, moon and stars." ”

This is also the reason why Li Chong pulled Li Chunfeng here.

But!

When he heard Li Chong say this, Li Chunfeng was still a little surprised.

Because Li Chong only said that he needed someone who knew astronomy to help him, but before coming here, Li Chongke didn't say that he wanted to make such a thing.

In other people think this life is a bit big.

After all, the sun, moon and stars, the ancients were always more or less superstitious.

For the sun, moon and stars, that is naturally the only respect, you now let them make a thing that simulates the trajectory of the sun, moon and stars, and suddenly feel that it is more or less sacred.

But!

But I also think it's very interesting.

However, after Li Chunfeng heard Li Chong say this, he had to interrupt Li Chong's beautiful fantasy.

Said:

"I don't know what kind of thing Master Li wants to make, simulating the trajectory of the sun, moon and stars? If it's an armillary sphere, then the Taishi Bureau already has it. ”

Everyone looked at this disappointing guy.

Li Chong also introduced at this time: "This is Li Chunfeng, the general of the Taishi Bureau. What I'm going to do, of course, is not what you said about the armillary sphere. I also know that the Taishi Bureau already has an armillary sphere. I wanted to make something very special, how to say, I'll draw it. ”

After that, the group went to the land outside the courtyard, and Li picked up a branch and drew his own idea.

"I want to make something like this, for example, the sun in the middle, and then, with the sun as the center, in turn, make the planets that orbit the sun, and the so-called planets are gold, wood, water, fire, and earth, and of course, the earth under our feet is also included in it. They're all round balls. The sun in the middle is a big ball, the others are small balls, and then all the planets rotate cycles around the sun. As far as I know, we have 365 days a year, and the rest of the cycle of gold, wood, water, fire, and earth depends on you. ”

Li Chunfeng patted Li Chunfeng on the shoulder, and continued: "Then use gears to connect them all so that they move in one and move them all." ”

Colleagues in the Academy of Sciences quickly understood what it meant, anyway, to make something that would go around in circles.

However, Li Chunfeng was not happy, and saw that his face was a little ugly and said to Li Chong: "Master Li, please allow me to say a word." ”

"You say."

"You're not messing around?"

Li Chong said: "Why did I mess up?" ”

"If, as you said, the sun in the middle and the outer circle is gold, wood, water, fire, and earth, then where are we?"

Li revisited the order for a moment and said, "We are also here, almost in this position, between Venus and Mars." ”

"That'...... We're also turning? ”

"Or else?"

Li Chong looked at him as a matter of course.

Li Chunfeng also looked at Li Chong with an incomprehensible expression. The two looked at each other like this.

That's right!

As soon as the rest of the people looked at it, they knew that there was going to be a debate next.

Maybe a fight is possible.
