There are several types of drip.

The principle of drip is to use the isochronicity of the fluid to count.

Fluids can be made of water or sand.

If you choose timing accuracy, use water.

As early as the Western Zhou Dynasty, the ancients invented the drip timing.

It was a cylindrical bronze pot cast in bronze.

The pot contains water and a faucet is underneath.

There is a lid at the mouth of the pot and a square hole is placed on the cover.

There is also a square handle that looks like a bento box handle.

There is also a square hole in the handle.

Two holes, the connection line is perpendicular to the horizontal plane inside the pot.

Put a small wooden board floating on the water in the pot, insert a wooden arrow on the wooden board, and carve twelve scales on the arrow.

Twelve scales are twelve hours.

This is called an arrow.

The arrow passes through the square hole of the lid and the handle of the pot, keeping it perpendicular to the water surface.

It's very simple when using it.

Turn on the faucet and release the water, and the water surface in the pot will gradually lower.

The floating arrows floating on the water will gradually decrease.

Observe from the handle, you can read the scale on the arrow, that is, time.

This kind of drip is called a leak pot.

One disadvantage of the leaking pot is that it is not accurate enough.

During the timing process, as the water leaks more and more, the water surface gradually drops, the pressure will gradually decrease, and the leakage speed will become slower and slower.

Time is not accurate.

Zhang Heng of the Han Dynasty improved the leaking pot and invented the multi-level leaking pot.

The multi-stage leaking pot consists of four pots, which stand on the stairs, from top to bottom, namely the sun pot, the moon pot, the star pot, and the water bottle.

Three pots of sun, moon and stars, just release water.

The purpose of such multi-level water release is to maintain the constant water pressure of the star pot and keep the speed of the star pot leaking.

When the speed is constant, the time is accurate.

The drip of the water bottle and the single pot are similar, but when the timing is counted, the arrow goes from falling to rising.

This multi-stage drip has greatly improved accuracy, 24 hours a day, and the error does not exceed 40 seconds.

This record lasted for more than 1,500 years until the Qing Dynasty when Europe invented a single pendulum timer, which was not broken.

In addition to using water, the ancients also invented hourglass.

In winter or in the north, the water will freeze, which affects the use of the leaking pot.

The ancients invented a timer to replace water flow with quicksand.

The "Five-wheel Hourglass" invented by Zhan Xiyuan in the early Ming Dynasty is the most outstanding one.

The five-wheel hourglass has a clock face like modern times, with hands, and can automatically call the time.

Apart from driving force, it is almost no different from modern mechanical clocks.

However, all hourglass shortcomings are the same, with poor accuracy, one hour and four or five minutes errors are normal.

The error is too big.

The reason for the error is the smoothness of the surface of the sand grain, as well as the smoothness and inclination angle of the container.

After careful thinking, Ye Qing prepared to make two timers at the same time.

One is to place it near the sundial and proofread it every day.

The time of this timer is used as the standard time of the tribe.

Then, a portable hourglass is made so that the tribe members can carry it with them.

This kind of timer has low accuracy requirements and can only count for a period of time, similar to a stopwatch.

But this is enough.

At the exact time, there is a tribe's clock.

When the bell of the worker rang, the team leader or neighbor took out the hourglass and started the timing to know how long the latecomer was late.

This kind of hourglass is best made of transparent materials.

Naturally, Ye Qing invented glass.

Once the glaze is made, glass is not a problem.

Although the transparency is not good, it is enough to make an hourglass.

The materials have been solved, Ye Qing has golden fingers, so there is no problem with processing.

It was just a little hard work, he made all the hourglasses by himself.

Ye Qing decided to improve the five-wheel hourglass to change the quicksand power to water flow power.

Anyway, the tribe is located in a very warm winter and has never frozen.

He used Zhang Heng's multi-stage leak pot on a five-wheel hourglass and used a constant and constant speed of water to drive the gears to rotate. After several gears decelerated, the pointer rotates to indicate the time.

Adjust the water flow so that the speed of the pointer is consistent with the speed of the projection of the sundial needle.

Five rounds of leaking pots were finished.

Under Ye Qing's golden finger, this is not difficult.

All the huge machinery such as brick making machines have been made. This exquisite device is even more handy for gold fingers.

In order to prevent the tribes from operating incorrectly and affecting the accuracy, Ye Qing added the entire device to a shell and encapsulated it.

This timer is also fool-proof.

The tribe members only need to add water regularly, and at noon every day, check the time according to the sundial.

The dial is also made like a dial.

The tribe members have become accustomed to reading time in a dialect. If they make it the same, the tribe members do not need to adapt again.

It also facilitates proofreading of both.

When these two timers were put into use, the tribe members were trembling and inexplicably awe.

They can also be regarded as a ritual instrument when using sundials.

The sundial timing uses the sunlight of the sun.

This made them subconsciously feel that it was God or God involved in it.

One of the ritual instruments that God participates can time, and they can understand.

As a god, he can do everything, and timing is naturally no problem.

But the two timers now have been separated from the weather and the influence of sunshine. They can be free from the weather restrictions and can be timed independently.

There is nothing wrong with the gods here.

And what is used to count?

It's water!

It's sand!

This is the most common thing.

Moreover, Ye Qing made two timers, and the tribe members also saw them. The materials used were all available in the tribe and could be obtained by the tribe members. The production process was not kept confidential, and it was simpler than a brick making machine.

What does this mean?

This means that when the skills are good enough, any tribe can make these two timers again according to Qing's method.

Ye Qing is a god and can make timers, they can understand.

But now, people can also make timers, and they can't understand it anymore.

How can people make timers?

How can humans compare with gods?

But now...

People, really, can be compared with gods!

The brick making machine is made and can make bricks automatically. They are not so shocked because the brick making machine makes bricks.

And the timer is timed.

Time and bricks are completely different.

Bricks are real objects and can be pinched at will.

Time is invisible, invisible, intangible, contains life and death, and contains infinite mysteries.

There is no comparison between the two.

Then, a timer that can be timed naturally brings mystery.

But, such a mysterious timer...

People can also be made!

The three views of the tribe members have been completely subverted!

Some are trembling, some are terrified...

Some are in dismay, some are disgusted...

Some are concentrating on thinking, some are ecstatic...

This is a baptism and a spiritual storm!

After discovering the reaction of the tribe, Ye Qing was stunned.

The primitive people's perception of heaven and earth, nature, and everything, are incomprehensible to modern people...

Ye Qing didn't understand either.
