The short video shows the ancient times, and the emperors cried with envy!

Chapter 113 The four great inventions of the compass!Spring and Autumn Mohists: Can meteorite iron be ground into fine needles?

Spring and Autumn Period Bian Que: How dare you call this scum a doctor?
Sun Simiao of the Tang Dynasty: Bah!

Li Shizhen of the Ming Dynasty: People in the world say that snakes and scorpions have a heart, but women and villains are the only ones who are difficult to raise. It’s nothing more than this!

Of course, many people are curious.

What exactly is a so-called birth certificate?
Great Qin.

The First Emperor Ying Zheng had already had a rough idea of ​​the population of future generations.

But he really couldn't imagine what the so-called birth certificate was?
Turning his gaze, Li Si frowned on the side.

After seeing the gaze from the First Emperor, Li Si was stunned for a moment, but then he tentatively asked.

"His Majesty!"

"Could this so-called birth certificate refer to a certificate similar to an official deed?"

As soon as the words came out, Li Si's voice fell.

That's right, but it's such a huge amount of work. It's impossible for anyone to register all the babies born in the country one by one!
Besides, what if it’s registered?

If you really have to check it again, the manpower consumed will probably be no less than when you registered!

Li Si racked his brains and couldn't figure out how the baby's birth certificate and the birth certificate were connected.

But at this moment, Ying Zheng's mind has been withdrawn and he has turned his attention to other places.

Birth certificates aside, this act of selling babies is truly abhorrent!
If it is according to the laws of Daqin.

Kidnapping and trafficking are the same crime, and all of these are punishable by death; those who know and fail to report will be punished by having their noses chopped off.

What's more, this person is actually the director of a hospital. Knowing the law and breaking the law will be punished with an additional penalty!
Thinking of this, Ying Zheng snorted coldly.

"Lis!"

"Pass the widow's orders"

"Investigate the prisoners in Da Qin, and those who commit the crime of abduction and trafficking will be killed!"

Li Si quickly accepted the order. In the past few days since the sky curtain appeared, His Majesty is really busy!

In the Tang Dynasty, the monarchs and ministers in Chang'an City looked at the scene in front of them with strange expressions.

"Hospital? Could it be a medical center!"

"Doctors save lives and heal the wounded. How could there be such a madman who would commit such a heinous crime by taking advantage of his own advantages?"

"I'm afraid this hospital is not a good place to treat diseases and save people. Instead, it is a devil's cave that has been run by thieves like this for a long time!"

"It's really hateful. If I meet such a thief, I will cut off his head with a sword!"

"According to the laws of the Tang Dynasty, although slaves can circulate freely, those who traffic in people should be hanged as a warning to others!"

While everyone was discussing, Tang Taizong Li Shimin's eyes became more and more serious.

Human trafficking, and also baby trafficking!

How can he be allowed to cause such harm to the world?

When he thought that his beloved Princess Sizi was only in her early years, Li Shimin's anger became even deeper.

"Humph!"

"Thieves like this really deserve to die!"

"It is my decree that anyone who has a baby among the missing people in the future will be sentenced to death without any reduction in punishment!"

"Anyone involved in the abduction and trafficking of babies and young children will be severely punished!"

"The culprit who knows the law and breaks the law must punish the three tribes to set the record straight!"

As soon as these words came out, everyone present immediately fell silent and accepted the order one after another.

But the anger in Li Shimin's eyes did not diminish at all.

"In Datang Prison, all those who have committed trafficking crimes have been re-tried. Those who have committed the above crimes will be dealt with immediately!"...

[It is reported that Ye Moumou was once criminally punished for illegal induction of labor, and this time he was involved in another crime, which was of a vile nature!The maximum possible penalty is the death penalty. 】

[The relevant hospitals involved have been closed for rectification! 】

"death penalty!Good kill! 》

"This scum should have been sentenced to death long ago!" 》

"How can we bring justice to the parents who have lost their children without imposing the death penalty?" 》

"Don't open this kind of hospital that harms people!" 》

The Wan Chao audience couldn't help but clap their hands and cheer. After seeing this ending, the depression in everyone's hearts was slightly relieved.

Gu Sheng also sighed secretly in his heart, and then continued to slide the phone screen.

[The compass is one of the four great inventions. Its invention played a vital role in the development of human science, technology and civilization. #Technology#Four Great Inventions of Ancient China#Compass]

【compass!In ancient times, it was also called Sinan and it was one of the four great inventions in my country. 】

Accompanied by a low voice-over sound, a compass structural shadow instantly appeared on the sky screen.

"During the Spring and Autumn Period and the Warring States Period, people discovered and recognized the uniqueness of magnets, and thus made Sinan!"

"After the changes of the times, today's Sinan has gradually evolved into the appearance of a compass!"

A comparison of two items instantly appeared on the sky screen.

Although the principle is the same, Sinan's shape undoubtedly looks much larger. On the contrary, the compass is just a small one.

The huge body size difference was immediately apparent, and the voiceover continued.

"The structure of a compass is an axis and a magnetic needle that can rotate freely around the axis. Apart from that, there are almost no other components required."

"The structure of Sinan in ancient times was composed of a bronze floor and a magnetic spoon! The floor was engraved with the scales of the heavenly stems and the earthly branches. After the magnetic spoon calmed down, the head of the spoon faced north and the tail of the spoon faced south!"

"Sinan can be said to be the earliest device invented by people to identify directions. However, due to the cumbersomeness of Si Nan, it gradually evolved into a compass!"

“In our country’s exchanges with other foreign peoples, the compass developed and became popular in Europe following the footsteps of the Arabs.”

Under the canopy, countless spectators raised their heads.

compass?Si Nan?

For those working people, these things have never been heard of.

But for some scholars who have dabbled in other miscellaneous matters, as well as those leaders at the top of power, this stuff is not unfamiliar.

After all, there are always times when you need to know the direction when marching and fighting, and Sinan's role is reflected here.

Of course, Si Nan can also be used as an expert.

However, the information revealed on the sky screen that everyone is more concerned about at this moment seems to be far from that simple.

Spring and Autumn and Warring States Period.

Everyone in the Mo family looked at the image of Sinan that appeared on the sky, and then glanced at "Si Nan" in front of everyone. At this moment, everyone gritted their teeth.

Compared with the Sinan on the sky screen, the Sinan they created was simply crude.

Even the Sinan spoon was not polished evenly, and the confusion in everyone's hearts was indescribable.

Why?
This kind of meteorite iron is extremely difficult to polish and will break if you are not careful. How did later generations polish it so smoothly?
Of course, everyone was more shocked than that.

That thing called a compass is the real dimensionality reduction attack.

compass?Si Nan Zhen?
The disciples of the Mo family looked at each other. How could they never imagine that meteorite iron could be ground into fine needles?

How did the later generations do it?
In everyone's opinion, this meteorite iron creation points north and south because of certain qualities in its body.

How can a structure as small as a compass bear this quality?

What’s more, it can continue to work!
