Video spoilers history, starting with the blitzkrieg on Poland

A new sky appeared.

A scene of a southern primeval forest appeared on the screen, with a group of soldiers in armor advancing hard in the forest.

Although they don't like the environment of this dense forest very much.

But it can be seen that morale is still high.

And they quickly defeated some local indigenous soldiers.

But just as they passed by a denser forest.

Several arrows suddenly flew out from the shadows in the woods nearby!
The whizzing arrows hit the armored soldiers.

Most of the arrows were blocked by armor, but a few soldiers were slightly scratched.

After all, they are just arrows from the indigenous tribe. They are not very sharp and their power is not very great.

The soldiers quickly fought off the ambushers.

The soldiers didn't care.

But he didn't take a few steps.

Those soldiers were slightly scratched by the arrows of the natives.

He suddenly showed a painful expression.

He soon fell to the ground and died.

So people all know that those seemingly inconspicuous arrows actually hide deadly toxins.

And the story officially began.

[When it comes to the most poisonous plants in the world, many people will think of poisonous mushrooms or oleander. 】

[But the one that can really kill people is actually this - the curare tree! ]

[The name of this tree sounds murderous, and its toxicity is even more true:]

[As long as the wound is stained with its juice, an adult's heart can stop beating within a few minutes. ]

[In ancient times, it was painted on arrows to make biological weapons, which frightened the enemy. ]

[Today, it is still the most dangerous silent killer in the rainforest. ]

See the first paragraph of the story.

And those bloody scenes that appear in conjunction with the story.

Many ancient people were interested in this magical plant called curare, nicknamed the poisonous plant.

Or rather, be vigilant.

Qin Dynasty.

Ying Zheng looked at the highly poisonous strychnos nux vomica tree on the sky.

I couldn't help but frown.

"Sure enough, it's not easy for a large army to move in this Lingnan area."

"The land is filled with miasma and poison."

“Even ordinary plants are so poisonous!” I’m afraid that the Lingnan Legion of our Great Qin has suffered heavy losses while developing the land there.

While lamenting the difficulty of the Lingnan Army in expanding its territory, Ying Zheng was also thinking.

And he said: "The Qin crossbow of my Great Qin is unrivaled in the world."

"Especially after destroying South Korea, absorbing the essence of South Korea's crossbows has raised the technology and power of the Qin crossbows to a higher level!"

"What if we import some of the Bloodthirsty Throat from Lingnan and form a special Bloodthirsty Throat Qin Crossbow Corps?"

"When fighting, carry out high-density crossbow strikes."

"It is not required that every arrow should cause fatal damage."

"But if this poison is really that poisonous, as long as it touches the wound, there is a chance that it can kill the enemy!"

"Although it's just a trivial trick, if used at a critical moment, it may also determine the outcome of a battle?"

Ying Zheng himself was not a king who was good at commanding battles.

But after a rough thought, I feel that the Strychnos nux vomica is indeed worth introducing.

……

The curtain continued and the formal introduction began.

[The scientific name of the arrow poison tree is Antiaris toxicaria, which belongs to the Moraceae family. ]

【Grows in tropical and subtropical regions. 】

[In my country, it is mainly distributed in Guangdong, Guangxi, Hainan, Yunnan and other places, and abroad it is more common in India, Sri Lanka, Myanmar, Vietnam, Cambodia, Malaysia, Indonesia and other countries. ]

[This tall tree can grow to 25 to 40 meters when it matures, which is equivalent to the height of a 10-story building.]

[It has a huge crown, dense branches and leaves, oval leaves, shiny surface, and evergreen all year round. ]

[From the appearance, the curare tree is not much different from ordinary trees, and it is even somewhat elegant. ]

【But it is called the "ghost tree" or "death tree" by the locals. 】

[Because at first glance, the arrow poison tree looks no different from an ordinary tree. ]

[But in fact, its juice contains a highly toxic ingredient. ]

[Its toxicity mainly comes from the milky white sap secreted from the trunk and branches. ]

[These venoms contain a variety of toxic components, the most important of which are cardiac glycoside compounds, such as cyathula glycoside and cyathula glycoside.]

[When these ingredients enter animals or humans, they quickly act on the heart, disrupting the electrical activity of myocardial cells, causing arrhythmias, and then causing the heart to stop beating.]

【Just a few milliliters of venom. 】

[It can suffocate a strong bison to death in just a few minutes. ] [It is precisely because of its strong toxicity that in ancient times, local residents knew how to use the poisonous juice of the arrow poison tree to make poison arrows. ]

[In Southeast Asia, indigenous tribes collect the sap of the arrowhead tree and apply it on their arrows to make poison arrows.]

[Once the bullet hits the enemy or prey, the toxin will quickly enter the blood. ]

[Prey shot by this poisonous arrow often fall to the ground and die before they can run far.]

【Greatly improved the success rate of hunting. 】

[Because of its extremely strong toxicity, those shot by the arrow often don’t even have the chance to call for help, hence the name “blood-killing throat”. ]

[This poison arrow is extremely powerful in tribal wars and hunting, and can even bring down fierce beasts such as elephants and tigers.]

[According to legend, hunters from certain tribes would cut off the arrow shaft immediately after shooting their prey to prevent the poisoned arrow from rebounding and injuring the prey when it struggled, which shows how dangerous it is.]

[In addition to being used as a weapon, the toxicity of the curare tree also makes it a strange place in medical history. ]

[In the 19th century, European colonists explored Southeast Asia and recorded that local indigenous people used the sap of the arrow poison tree to execute people.]

[As long as the victim has a wound on the skin and is exposed to the poison, he will die quickly without even a chance of rescue.]

【Because there is no antidote for this toxin. 】

[Modern medicine can only buy time through cardiopulmonary resuscitation and drug maintenance, waiting for the toxins to be metabolized. ]

[But what’s interesting is that although the arrow poison tree is extremely poisonous, it does not kill anyone who touches it. ]

[Its toxins must enter the body through the blood to be fatal, so simply touching the trunk or leaves will not cause poisoning.]

[Its fruits are even eaten by some birds, and its seeds can be spread by animals.]

[This "selective toxicity" is a peculiar survival strategy in nature.]

[It can keep natural enemies away without affecting their own reproduction. ]

[In modern times, scientists have made new discoveries in their research on the curare tree. ]

[Although its toxins are deadly, in trace amounts, they may be helpful in treating heart disease.]

[Similar to the principle of fighting poison with poison. ]

[Researchers are exploring how to exploit its anticoagulant properties to develop new drugs.]

[However, this research is still in the laboratory stage, so ordinary people should stay away from it. ]

[If you are exploring in the rainforest, how do you identify the poison tree? 】

[First, its trunk is usually straight, and the bark has longitudinal cracks.]

【Secondly, its leaves are oval in shape with clear veins. 】

[Most importantly, if you break its branches or bark, a milky white sap will flow out. ]

【And this is the source of the poison! 】

[Remember, never let this juice come into contact with the wound, not even with your hands. ]

[If you see it in the rainforest, observe it from a distance. ]

[But don't get close to it easily - after all, it is truly a "blood-killing" insect! ]

The sky video ends.

Netizens’ comments appeared one after another.

"There is a strychnos nux vomica tree in the South China Botanical Garden. I have been there to see it."

"I remember it, too. It was called Bloodthirsty Throat. I was shocked by this crude and direct name at the time."

"This thing is perfect for poisoning weapons."

"Guess why it is called the arrow poison tree?"

"Is Huang Rong's soft hedgehog armor made of this?"

"The arrow poison tree can even kill itself..."

Is the poison arrow tree a relative of the poison dart frog?

"As a Hainanese, I have seen three people hugging a curare tree, but don't try it lightly. There are small thorns on the outside of the tree, and it will hurt you if you get pricked."

"Can the fruit of the curare tree be eaten?"

"It should be possible, but no one dares to try..."

……

Three Kingdoms.

Zhuge Liang held a feather fan in his hand, his eyes fixed on the introduction of the poisonous arrow wood in the sky.

When he saw the video demonstrating how arrows coated with curare juice could kill a person instantly, he frowned slightly and slowed down the pace of waving his feather fan.

"There are such dangerous things in the south."

Wang Ping said, "Prime Minister, someone in Wudang's army mentioned that this tree is commonly seen in the dense forests of southern Yunnan, and the local natives often use it to paint their arrows."

Zhuge Liang nodded, thinking a little hesitantly.

"If this highly poisonous wood can be used properly, it may become a powerful weapon to defeat the enemy."

"But although this poison is strong, it is too dangerous."

"If used rashly, it may hurt innocent people if you are not careful..."

"However, for this kind of poison, we can secretly send someone to record its characteristics and methods of use, in case of emergency."

Zhuge Liang didn't want to use it actively.

But the possibility of use is reserved. (End of this chapter)
