I watched Er Chuang’s short video, and everything went numb!

[Although there are indeed many imaginary plots in costume dramas, the operation of "silver hairpin testing poison" is real. ]

[Song Dynasty forensic scientist Song Ci recorded in his book "Xiyuan Jilu" that "If you want to test for poison, use a silver hairpin to wash with soap water, insert it into the throat of the dead, seal it with paper, and take it out after a long time. It will be blue-black." ]

[It means: if you want to verify that the dead died of poisoning, then first wash the silver needle with soap, insert it into the throat of the dead, seal it with paper after a while, wait for a while, take out the silver needle, if it is observed that the silver needle is blue-black, it means that the deceased died of poisoning. ]

……

Southern Song plane.

Song Ci looked at the giant screen in the sky and his face was happy.

He was very happy that his book could be passed down to future generations hundreds of years later.

For the ancients, this is also a name that will be passed down through the ages.

Then.

Song Ci began to think again.

This "silver hairpin method of testing poison" has been passed down for many years, and in his practical experience, it has been verified many times, and it is indeed true.

Therefore.

He recorded this method in his book.

"What's wrong with this method?"

Song Ci continued to look at the giant screen in the sky with confusion.

...

[The silver hairpin that Song Ci mentioned is not the hairpin that the heroine of the TV series pulled out of her hair when testing poison. ]

[He is talking about a special tool, which is round and straight in shape, like chopsticks, but slightly thinner and longer than chopsticks, about one foot and two inches, which is about 30 to 40 centimeters when converted to ancient measurement. 】

[Each dynasty may be slightly different. This design should be to poke the throat deeper to ensure the accuracy of the test. 】

[This method was used until the end of the Qing Dynasty and was still one of the main ways of testing poison in the government office.]

[For example, the Xiaobaicai case occurred in the 12th year of Tongzhi, which was 1873 AD. 】

[The husband of a woman nicknamed Xiaobaicai died suddenly. After the coroner of the government office used a silver hairpin to perform an autopsy, the silver hairpin turned black, so he concluded that the deceased was poisoned and suspected that Xiaobaicai and his lover had killed him. 】

[There is a follow-up to this case, we will talk about it later. 】

The bullet screen flew out:

"Yang Naiwu and Xiao Baicai, one of the most unjust cases in the Qing Dynasty. "Justice, Magistrate" seems to be adapted from this case."

"These two people are too miserable. They were tortured into 08 moves."

"..."

The Tongzhi plane of the Qing Dynasty.

The bruised and disheveled Bi Xiu Gu, also known as Xiao Baicai, stared at the giant screen in the sky. Hope suddenly emerged in her dull and dead eyes.

Then.

She suddenly threw the brush in her hand away and shouted shrilly:

"I won't sign! I won't plead guilty! I am wronged! I didn't kill anyone!"

"Did you see that? People in later generations said that I was wronged!"

The officers on the side looked at each other, at a loss.

They had just tortured Xiao Baicai according to the order of the county magistrate Liu Xitong, and induced Xiao Baicai to confess in person.

Unexpectedly, just when Xiao Baicai was about to sign and seal, such a change occurred.

Finally.

These officers decided to report the matter and let their county magistrate make the decision.

……

[Back to the question of "Silver Hairpin Poison Testing Method", since our ancestors have really been using it, it proves that it must be effective. ]

[Why can't we test the toxicity when we use this method today? ]

……

Many ancient people in the past dynasties looked at the giant screen in the sky with much more concentration.

Next, the answer should be revealed.

……

[The reason is actually very simple. ]

[This method of testing poison is actually only effective for one kind of poison, that is arsenic, and has no effect on other poisons such as poisonous mushrooms. ]

[Or more accurately, it is effective for arsenic containing impurities. ]

[The main component of arsenic is arsenic trioxide, which itself does not react chemically with silver. ]

[However, due to the limited purification technology in ancient times, arsenic is often impure, and some sulfur or sulfide is mixed in it. ]

[When the sulfur element comes into contact with the silver needle, it reacts with the assistance of oxygen and quickly generates black silver sulfide, which makes the surface of the silver hairpin black. ]

……

"So that's it."

Many ancient people in all dynasties suddenly realized it.

Of course, they didn't understand the terms "arsenic trioxide" and "silver sulfide".

But they understood something from this passage.

That is, the "silver hairpin poison test" can only be used to detect whether there is arsenic, and other poisons cannot be detected.

After understanding this.

In many dynasties, the faces of many emperors and princes and nobles changed.

They were terrified.

It turned out that their poison test before eating could only prevent arsenic, but not other poisons.

If someone poisoned them with other poisons, wouldn't they be infected?

No!

These people looked at the giant screen and corrected their thoughts.

It doesn't have to be other poisons. According to the statement of later generations, as long as there are no impurities in arsenic, the silver hairpin cannot detect it.

Many emperors and princes and nobles were even more scared.

"If the silver hairpin method of testing poison is useless, how can we prevent being poisoned in the future?"

These emperors and nobles were very distressed.

At the same time.

Southern Song plane.

Song Ci looked at the giant screen in the sky and began to write furiously.

He wanted to revise the record of "Silver Hairpin Method of Testing Poison" in his book to avoid misleading future generations..

However, what he didn't know was that the ancient Chinese people of all dynasties had already seen this information from the giant screen in the sky, and there was no need for him to remind them.

……

[In fact, the fundamental reason why the "Silver Hairpin Poison Test Method" became popular was that the only highly toxic substance that could be stably mass-produced in ancient times and easily obtained by ordinary people was arsenic. ]

[The prescriptions prescribed by ancient doctors to treat severe diseases such as malaria included arsenic, and ordinary people could buy it casually in pharmacies. ]

[In addition, it was often used by the people to kill rats. Rats would die immediately after eating a little. Three-year-old children knew that this thing was highly toxic. ]

[To use the lines in comedy movies, "This is a must-have medicine for home travel and killing people." ]

[The murder weapon in poisoning cases is most likely arsenic, so the "Silver Hairpin Poison Test Method" is very effective. 】

……

"As long as you don't use arsenic to poison, or remove the impurities in arsenic before using it, no one will know."

Many evil-minded people in all dynasties had their eyes flashing and thought in their hearts.

……

【However, this operation also has serious flaws. 】

【Because the ancients did not know that sulfur caused the silver hairpin to turn black, assuming that something itself was non-toxic but contained sulfur, it might report a false alarm by mistake. 】

【For example, the natural decay of corpses will also produce sulfur. If you use a silver hairpin to examine the corpse, you will definitely come to the conclusion of poisoning, and various unjust cases will follow. 】

……

Wu Zhou plane.

Di Renjie was shocked and kept this information firmly in mind.

In the process of handling cases, he often used the "silver hairpin poison test method".

Now it seems that we cannot blindly believe in this method.

At the same time.

In the Southern Song Dynasty, Song Ci quickly recorded this information in the book.

……

[The Xiaobaicai case we mentioned earlier is a typical example of a false alarm. ]

[During the first autopsy, the body of Xiaobaicai's husband had begun to decay due to the hot weather, so the silver hairpin turned black. ]

[Later, the lawsuit was brought from the local to the central government. After the parties confronted each other, the coffin was opened and the bones were examined. It was found that there was no sign of poisoning, and only then was Yang Naiwu and Xiaobaicai's injustice ruled out. 】

The barrage flew out:

"The false alarm is one thing, and Yuhang County Magistrate Liu Xitong had a grudge against Yang Naiwu and wanted to take the opportunity to kill Yang Naiwu."

"In the end, the case became very complicated, involving the party struggles and power struggles within the Qing Dynasty at that time. The truth of the case itself is not important."

"In fact, there was no winner in the final result of the case. Yang Naiwu and Xiao Baicai escaped the crime of murder, but Yang Naiwu was sentenced to 100 strokes of the cane and was not allowed to restore his reputation. Xiao Baicai was sentenced to 80 strokes of the cane. Yuhang County Magistrate Liu Xitong was dismissed and exiled to Ningguta. Many other officials were punished. It can be said that they all lost."

"Reply-Why punish Yang Naiwu and Xiao Baicai? They did not commit adultery."

"Reply-becauseThe truth is insignificant. This sentence was issued because on the one hand, the central court wanted to take the opportunity to suppress local governors and maintain imperial power, and on the other hand, it wanted to preserve the authority of local government offices.

"Reply--Alas, these two people are too miserable."

...

"It is indeed miserable."

Many ancient people from past dynasties saw this and felt a little sympathy for Yang Naiwu and Xiao Baicai.

The Tongzhi plane of the Qing Dynasty.

Yuhang County Magistrate Liu Xitong looked at the huge screen in the sky, feeling terrified and sweating all over.

He had never expected that the matter would cause such a big storm in the end and that it would end up like that.

It is true that he wanted to take the opportunity to retaliate against Yang Naiwu, but he never thought of getting himself involved.

| =|

Being exiled to Ningguta was a matter of life and death.

This case could not be handled according to his original idea.

……

[What makes people laugh and cry the most is that, in many cases, the silver hairpin itself is defective. ]

[Wang Youhuai, a forensic doctor in the Qing Dynasty, wrote in "Summary of Handling Cases": "Silversmiths often replace real ones with fake ones, or match them with low-color ones. Even if they are witnessed in person, they can still cheat. Officials are unaware and use them incorrectly, making it difficult to identify injuries." ]

[Everyone should be able to understand this passage, which means that silver hairpins are always adulterated by craftsmen, and the government office takes them to test for poisons and they are completely inaccurate. ]

[From the above, it can be seen that the toxins that can be detected by silver hairpins are very few, and the limitations of using silver hairpins to test for poisons are simply too great. ]

……

Watch the entire video.

Many emperors and princes and nobles in the past dynasties were very distressed.

People in later generations only said that the "Silver Hairpin Poison Test Method" was unreliable, but did not introduce a reliable method of poison test.

What method should they use to prevent being poisoned in the future?

It was in the troubles of these people.

A huge screen at high altitude.

The video was refreshed.

A new video appeared.

[Space infrastructure, great power pattern-Longguo's "Heavenly Creations" plan to open the interstellar gate! ]

After this line of headlines, there was a short preface.

[With the rapid development of science and technology, mankind has entered a new space age. ]

[In this era, the development and utilization of resources are no longer limited to the earth, but have expanded to the vast universe. ]

[Longguo, as an important participant in the field of aerospace, recently proposed a grand plan called "Heavenly Creations", which aims to open the interstellar gate and realize the development of resources in the entire solar system by 2100. 】

【Today, let's take a look at what the "Heavenly Creations" plan is. 】

……

After reading this preface.

The ancients of all dynasties instantly became very interested in this "Heavenly Creations" plan.

"Opening the interstellar gate" and "developing the entire solar system" sounded magnificent.

And after watching many related videos before, the ancients already had a certain understanding of space.

They knew that it was very difficult to develop space.

Therefore, they were more curious about what the Dragon Kingdom's "Heavenly Creations" plan meant.

...

The Ming Chongzhen plane.

In a room.

Song Yingxing, who was writing furiously, stopped writing and looked at the giant screen in the sky, and then looked at the book he had just written in front of him.

The title of the cover of this book is exactly: "Heavenly Creations".

"Is it my book that has been passed down to later generations, or is it a coincidence?"

Song Yingxing thought in his heart.

The four words "Heavenly Creations" were not his original creation, but came from two Chinese classics.

Heavenly Creations comes from "Heavenly Creations, People Replace It" in "Shangshu".

Kaiwu comes from "Kaiwu Chengwu" in "Yi Jing".

So, Song Yingxing was not sure why the Dragon Kingdom named the "Heavenly Creations" plan.

……

[The total number of asteroids in the solar system known so far is about 1.3 million, of which about 30,000 are so-called "near-Earth asteroids" close to the Earth. ]

[According to the observations and statistics of the "Asteroid Database", about 701 of these asteroids have extremely high value. ]

[And based on the current technological level of mankind, among these 701 asteroids, about 122 have the possibility of mining, and the total value of these 122 asteroids with mining capabilities alone exceeds 750 trillion US dollars. ]

[Obviously, what flies over our heads every day are floating treasure houses 663. ]

……

Accompanied by narration subtitles.

An animated map of the vast space planets appeared on the high-altitude giant screen.

Listening to the narration and looking at the planets in the vast space, the ancient people of all dynasties were amazed.

Each planet is worth trillions of dollars. These are indeed priceless treasures!

Daqin plane.

Qin Shihuang looked at the giant screen in the sky and couldn't help but fantasize in his heart.

If his Daqin had the ability to develop these space treasures, how powerful would Daqin be?

Conquering the whole world is just a piece of cake.

Of course.

Qin Shihuang was just thinking about it.

He knew very well that Daqin could never do it.

"Can Longguo do it?"

Qin Shihuang continued to look at the giant screen in the sky.

...

[In order to develop these space treasures, there was a "Heavenly Creations" plan. 】

[Everyone should be able to guess the origin of this name. It is to pay tribute to the book "Tiangong Kaiwu" written by Song Yingxing, which is known as the "Encyclopedia of Chinese Crafts in the 17th Century". 】

……

See here.

Song Yingxing was delighted and excited.

He felt that this was his great honor.

……

[And, at a meeting of the Dragon Country Aerospace SocietyAt the scientific conference, an academician expert from Longguo has officially announced the roadmap of the "Heavenly Creations" plan. 】

[That is, this plan is not a PPT we draw, but has a clear time plan. 】

[Next, let's take a look at this roadmap. 】

……

The ancient people of all dynasties were instantly refreshed, and their eyes looking at the high-altitude giant screen became more focused.

They are very eager to know the specific content of this "Heavenly Creations" plan.

……

[The "Heavenly Creations" plan is mainly divided into three steps. 】

[The first step is to gradually build water resource development facilities on the moon, Mars, near-Earth asteroids and main-belt asteroids, and establish a space resource supply station system, so as to form the ability to explore the entire solar system. 】

[The second step is to build space resource supply stations, space transportation channels, extraterrestrial mining stations, space resource processing stations and other related facilities to form multiple extraterrestrial resource development, production and transportation systems such as lunar resource development, near-Earth asteroid resource development, Mars development, and main belt asteroid development. 】

[The third step is to focus on the layout of space entry and exit, space transportation, space supply, space mining, and space resource processing technologies, and focus on breakthroughs in common key technologies such as low-cost resource return, flight-based space resource transportation, space resource supply stations, extraterrestrial mining stations, and space resource processing stations. 】

……

Accompanied by narration subtitles.

In the introduction of each step, relevant animation demonstration images appeared on the high-altitude giant screen.

While watching, the ancients were amazed in their hearts:

"What a grand plan!"

"The Dragon Kingdom's hand is too big!"

No doubt.

If this "Heavenly Creations" plan can be completed, the future development of Dragon Country will be unimaginable.

The ancient people of all dynasties were deeply shocked and admired by the grand pattern of Dragon Country.
