Sending those people away, Gao Li was finally able to do what he liked with peace of mind. There are a lot of things going on in the city, how can there be so much effort to accompany them to waste time?

However, speaking of time.

Gao Li desperately needed a timer.

There is a flow timer in this world that can make do with it, but it is only for it.

At the beginning, it was not possible at the machining level, so Gao Li had nothing to do. Now that the finishing has reached a certain standard, Gao Li can finally make something he has wanted for a long time.

Pendulum clock.

The pendulum principle, the simplest principle in the world. In the laughing range, the time for a single pendulum to swing once is only related to the length of the single pendulum, and the amplitude of the pendulum is not related to the mass of the weight. This means that the pendulum is probably the most convenient mechanism in the world for keeping time.

At this time, Gao Li really had to thank the education he had received, and all the knowledge that seemed to be useless back then came in handy at this moment.

A hammer, a slender connecting rod of adjustable length, is attached to the escapement, and each time the two pawls grasp the gear, it is a second. A method that provides energy storage, a set of calculated gears, and two hands that make up the whole of a pendulum clock.

The gravity of this world feels similar to that of previous lives, and the length of a single pendulum is only one meter. There are only hours in this world, twelve hours in a day. Gao Li designed the shape of the clock according to this, one second is still one second, one minute is still one minute, but an hour is one hundred and twenty minutes.

The mining of chromium alloys has made it possible to make the law bar and the strong gear, and the gear can also be made bigger to meet the strength, but the law is definitely the thinner the better.

At first, everyone didn't understand whether the so-called timer made by Gao Li was really useful, because in the eyes of ordinary people, the speed of the single pendulum swing should be slower and slower. But everyone was very curious about this thing, so they made one according to their words.

On the law, swinging a single pendulum, accompanied by this crisp click, the world's first pendulum clock, just like this.

Because the box has not yet been made, all the gear parts are placed outside, and anyone can see how this timekeeping machine, which is made of too pure metal, works.

Anyway, after the installation, the people in the scientific research team watched it all morning, and they were busy for a while, so they came to see it twice, and they were busy for a while, so they came to see it twice, which was very interesting.

Looking back now, Galileo, who discovered the monopendulum isochronous, was also quite remarkable.

In the beginning, the pendulum clock was not very precise and did not meet the requirements of twelve hours in a day. Gao Li took this pendulum clock to the upper floor of the city, where there were missing engravings and sundials, and the time could be calculated by calibrating each other. When Gao Li got such a mechanical thing, the expressions of several watchmen in the building were very rich. They had never seen a pendulum clock before, and when Gao Li said that this thing could keep time, everyone felt amazing.

"Hey buddy, you said there is no fine sand and no water here, can you do it?" asked one of them secretly.

"What do you know! I can tell you, my brother told me, our lord is a man of great wisdom! Don't look at the lack of water and sand here, people are still accurate! Don't you see that the name of the twelve hours is engraved on it?" said the other man.

"You talked about it for a long time, but you didn't explain it. ”

"Nonsense, I have to understand!"

"So you don't understand!"

"I've never seen this thing, how can I understand?"

"I don't understand how much you say, as if you understand so much. ”

"Hey you guy......"

Gao Li turned his head, looked at the two husbands, and said with a smile: "Are you two talking about cross talk here?"

The two husbands, one short and fat, the other tall, immediately laughed and said: "Wang Ye Haihan, this is just our brothers, and they usually like to mix when they have nothing to do." Where have we ever seen such a great man as Lord Wang in our lives, my heart is nervous, and my mouth begins to talk nonsense, don't go to your heart. ”

Gao Li smiled: "Hometown Shangjing?"

The short and fat husband said: "Those from Jincun on the outskirts of Beijing." ”

"How did you get here?"

"One day, my father was talking cross talk in the teahouse, and Liu Fu, the right minister, passed by and said that my father did not respect the emperor, and our family was sent here. ”

"It's really disrespectful?"

"Actually......"

"Actually?"

"Actually, it's really disrespectful, my father's mouth, it's not accurate to smash it. The short and fat man said with a sad face.

"Don't follow him. "Gao Li Dao.

"Surely not! I'll talk about him now!" said the short and fat groom, a tall gentry next to him.

"I'm idle anyway, you two tell me a paragraph?" Gao Li said with a smile.

"The prince likes to listen, then let's tell you a paragraph, talk about the father next to me......"

By adjusting the swing arm to fine-tune the time, Gao Li came to listen to a cross talk every day, and after a few days, the clock was relatively accurate. And the pockets of the two husbands are also rich.

It seems that it should be time to tear down the changing building and build a bell tower, Gao Li thought so.

With a pendulum clock that can accurately time, this brings great convenience to the research team, because for the first time, they can accurately record exactly how and how certain phenomena occur. It was during this time that Yun Qingyang quietly left and set off for the West. Although Gao Li didn't know the specific time, he could see a hint of clue from Xiaomi's face.

Hey, I don't know if Yun Qingyang and Mi Fu saved the world in their last life, and they can have such a good child as Xiaomi.

Now in Yannan City, Gaoli focuses on two products. One is rubber, whether it is tires or rubber pipes or even elastic bands, which are luxury goods that have never appeared in the world. Second, it's chocolate. Tons and tons of imported cocoa beans from Yong'an, fermented and roasted to make chocolate. The biggest problem now is that there are not enough sugar crops.

The northern bear demon has not yet thawed, so I can't count on it. Yanan also did not cultivate sugarcane on a large scale, and now he can only use honey instead, which Gao Li always feels is too luxurious.

Fortunately, the climate gradually became more suitable for farming, and the sugarcane stored in the sand was finally able to come in handy.

At this time, many people in the city were carrying out the reconstruction of Yannan City, and only a small number of people were able to farm, and it happened that there was only one tractor on Gaoli's side. Plough the ground and ridge up. By cutting the cane into sections and burying it in the soil, the cane that is about to sprout in the sand will soon take root and more can be harvested this year.

Then, a small sugar factory will rise here.

From here, the sweet gold will be sold to the whole world.

At this moment, Gao Li stood on the big head of the iron puppet, looking at the city below that was being rebuilt in full swing, and his heart was infinitely emotional. He was taking a deep breath and wanted to improvise a rap, but suddenly saw two clouds of smoke and dust outside the city approaching rapidly, extremely fast. And behind that smoke, thick smoke billowed out.

Gao Li took out his beloved monoculars from his arms, and when he looked closely, the smoke and dust in front of him turned out to be a handsome donkey! Next to it were a group of Pegasus with broken wings, and there was a person lying on the back of the Pegasus, Gao Li couldn't see the person's appearance clearly, but he knew the giant sword on her back!

Qin Duanyu?

Gao Sen said

Inside, didn't I explain it before, my mother is hospitalized...... A little less.,It'll recover when this time passes.,Okay?baa~~
