Destiny Only Han

Guanzhong, Chang'an City.

The heavy snow has dyed everything white, the bright sunshine in spring hides in the haze, the swaying leaves in midsummer wither darkly, the whistling wind takes away the warm atmosphere, but the Weishui under the ice never stops rushing pulsation.

East Palace, a side hall as warm as spring.

Liu Ying squatted on the ground, with a lot of bits and pieces in front of her.

In fact, early in the morning, he planned to go hunting in the mountains south of Shanglin Garden. After all, there was thick snow on the ground, and the traces of wild animals were clearly visible, so he should have a good harvest.

But when he cheered up and walked out of the palace gate, he turned back in less than half a minute.

Cold, really cold.

So, it's better to stay warm in the palace and make a handicraft, anyway, he doesn't lack that piece of meat and fur...

What Liu Ying wants to do is a set of simple pendulums, using a single pendulum as a simple harmonic oscillator and a weight as a power source for the clockwork.

When precision is not required, it is extremely simple to make, as long as you have hands.

Well, the orbit of the earth is not uniform, especially under the interference of the moon, each day is not actually 24 hours with exact minutes and seconds, so there will be adjustments such as leap years and leap months.

For the clock that Liu Ying made today, the source of the mechanical restoring force of the gravity pendulum clock is the gravity of the pendulum.

That is to say, the reason that affects the timing accuracy of the clock is the stability of the oscillation period of the oscillation source itself.

This requires the clock to be in an inertial system, and the equivalent gravitational acceleration G value it receives should be stable, and the direction and size cannot change.

"The Ronin from Douluo"

"What are you doing in a daze? Come here!"

Liu Ying waved her hand, and called Zhang Buyi who had just walked from outside the palace, his nose was red with cold, to come over.

"Can you be more polite to me? What do you call a dog? You know, I'm your future..."

"Puuuuuuuuuuuu..."

In the side hall, time seemed to freeze in an instant, and the quiet needle drop could be heard.

Zhang Buyi's face flushed red, and he rushed forward waving his arms: "I'll fuck you! Don't run away if you have the ability..."

"Wrong, wrong... really wrong, really wrong!"

Liu Ying opened her hands while running and parrying, but turned her head to look at Zhang Buyi, who was chasing after him with blushing cheeks, and felt more and more gay in this guy...

After chasing him for a few steps, seeing Liu Ying sincerely apologize to him, Zhang Buyi forgave him graciously, after all, this is a friend who grew up with him, and will be his brother-in-law in the future.

"Tell me, why did you call me over today?"

"I want to make a watch, I need a coolie, bah, a helper!"

With Zhang Buyi's eyebrows suddenly raised again, Liu Ying hastily changed her words and continued: "Besides, this is also a novelty, you have never seen it before! And the financial report for the fireworks show has been made, so it's not like you are [-]% Is it right? I will give it to you when I leave."

Hearing Liu Ying's words, Zhang Buji immediately grinned.

He is not interested in any novelties, what he prefers is the dividend that Liu Ying said.

Although Zhang Buyi has several streets of shops, hundreds of thousands of acres of land, and considerable bonds and shares under his name, he is neither married nor old enough to be crowned, so these things and the corresponding His mother is in charge of all the income, he is poor every day, and from time to time he has to be cheeky to ask Liu Le to borrow money...

...

Because of this, he once heard Liu Le say that in this cold world, only yellow gold can bring warmth to people...

At that moment, he couldn't help feeling that a confidant was hard to find...

Therefore, at this moment, Zhang Buyi suddenly became hardworking.

Under Liu Ying's command, he struggled to lift a single pendulum with a length of more than two meters, and completed the installation according to Liu Ying's requirements.

"Hold it up first, I'll put the pallet on..."

Liu Ying ordered, and searched on the ground according to the number.

The so-called pallet fork is a switch device for mechanical energy transmission. This switch is controlled by the timing reference. The balance wheel completes the distribution of time and achieves the role of speed regulation, thus indicating accurate time.

With Zhang Buyi's curious face, Liu Ying kept holding up a bunch of custom-made gears and started assembling them.

Well, things like gears have existed for a long time. For example, real objects have been unearthed from the tomb of Emperor Wen of Han... Of course, many feudal dynasties in later generations went to the wrong tomb, and this is another topic.

And because the period of the simple pendulum designed by Liu Ying is 3 seconds, the period corresponding to one tooth is also 3 seconds, and therefore, the number of teeth of the pallet fork gear is 20.

"Okay, you can let go there and hold on here..."

Zhang Buyi responded, and then looked at Liu Ying holding the mallet and aiming at the direction of his hand, opened his eyes and questioned:
"What are you doing... Ouch!"

Liu Ying's shoulders moved involuntarily, shaped like an iron mountain. After a while, she said with contempt: "I'm afraid of a ghost, I won't hit your hand!"

What he is doing now is connecting pendulums and gears with rivets.

In this way, a simple table clock is basically assembled. As for the rest, it is handed over to the craftsman to modify the appearance, inlay gold and jade, and make it look like ordinary people do not even have the courage to look at the price.

"That's it?"

Zhang Buyi scratched his head, and looked at the weird-looking wooden box about one foot high in front of him for some reason.

Liu Ying stretched out her hand and snapped her fingers: "Next, it's time to witness the miracle!"

After he finished speaking, he hung two heavy hammers with chains on a thick gear, and then passed through several acceleration gears, and brought the driving end of the second hand, and then saw the second hand move one by one.

Tick, tick...

Liu Ying looked at Zhang Buyi, who was confused, and explained: "This is called a clock. It is a tool for timekeeping. It is the same as the corona hourglass, but it is more accurate than them."

"The twelve intervals on the dial represent the twelve hours of day or night. Well, one hour is equivalent to half an hour. There are twelve hours in a day, and there are 24 hours..."

While Liu Ying was speaking, the minute hand was pointing to the top of the dial. Driven by gears, the yellowing device installed on the back of the clock hit the hammer heavily, making a crisp sound of gold and iron.

"Well, it's one o'clock now, so the clock will automatically ring once, if it's two o'clock, it will automatically ring twice, and so on, until it rings twelve..."

...

In Liu Ying's casual explanation, Zhang Buyi's eyes widened, his mouth opened slightly, and he stared at the pendulum in front of him in shock.

He couldn't believe that this thing was actually assembled by him!
Zhang Buyi doesn't care about the timekeeping property of the clock. His family is a family of bells, and there are tools such as hourglasses and servants in charge of telling the time.

What he cared about was how much such a rare item would sell for?
Just, I really want to have it!

Liu Ying saw his longing from Zhang Buyi's eyes, and just stretched out her hand to pat his shoulder: "You should hurry up and grow up, you still can't afford this now, or wait until the teacher empowers you. Bar!"

Although he is not sure how much a self-ringing clock will cost, he has read "A Dream of Red Mansions". Wang Xifeng once complained about lack of money and had to sell a gold self-ringing clock at home for 560 taels of silver (see Chapter 72).

Now, according to the official price set by Liu Ying himself, a silver dollar contains four grams of silver, and one tael is roughly calculated as fifty grams, so the chime bell in the Red Mansion is worth about seven thousand silver dollars, or 70 yuan!

During the years when Cao Xueqin wrote about the Red Chamber, trade between the East and the West was already very frequent, and the technology and industry of hand-made clocks in the West were also well developed, so the supply of chime clocks increased, and the price naturally showed a downward trend.

But it is different now, the chime bell made by Liu Ying here is the only one in the shit of a scorpion!
Therefore, it is normal to multiply by ten or eight times!
That's it, no discount!
After all, rich people only buy the expensive ones and not the right ones. If the price is set low, people think you look down on him...

This self-ringing clock is just a product made by Liu Ying at this stage to test the water and to practice.

He was going to hide it first, and he didn't make a big show of it. Instead, according to this structure, he installed a taller mechanical clock at the reserved position at the south gate of Changle Palace.

In this way, all the people in Chang'an City will hear the sound of bells, from hearing the chicken to starting a beautiful day in the sound of the bell...

Well, the name is Drum Tower...

After people become curious about this big guy and he has prepared a certain number of chime bells, then on a suitable occasion, let the fat sheep see such a rare thing that can be placed at home.

Imagine the scenario.

Fan Hui hosted a banquet at home for the meritorious officials of Peixian County and Chang'an City. At this time, a seemingly inconspicuous self-ringing bell rang out bursts of bells, which contrasted with the big bell on the Drum Tower outside.

At this time, people discovered that Fan Hui had randomly placed treasures worth tens of thousands of acres of fertile land as decorations.

And Zhou Bo, who likes to compete secretly with Fan Hui, is afraid that even if Zhou Yafu is given to Liu Ying, he will find a way to buy a bigger and more expensive one and put it at home, and then entertain Fan Hui to pretend to be forced back... …

Therefore, when talking about luxury, practicality is not worth mentioning.

When Brother Kong Fang flashed in Liu Ying's eyes, Zhang Buji asked unrelentingly: "Didn't you say that you would give me a dividend today? I still have some private money. I can't afford the big one, and I can't buy a small one." ?”

Uh, the smaller ones are more expensive... Liu Ying casually took out the money note and the revised financial report from the box and photographed them in Zhang Buyi's hands.

"Well, enough brother, I sent... Hey, what does this mean?"

"That's your fiancée's spending record...and, well, it's deducted from you anyway!"

Zhang Buyi looked at Liu Ying's evasive eyes, although he thought it was weird, but he still put the money note into his arms carefully with a smile on his face.
