For example, the cinchona tree in front of Zhou Yun.

A layer of tender red leaves. A layer of old green leaves.

There are many stories of cinchona trees. Anyway, it saves countless people.

40% of the planet's phytomedicines come from more than 2 million square kilometers of Amazon rainforest.

Journal of Medicine. Review of the 10 most important plant medicines. 4 species are from the Amazon rainforest. There is 1 species from Changbai Mountain. That's the fragrance.

Amazon rainforest. 95% of jungle humans have ever set foot in it. 60% of the plants in the Amazon rainforest are unknown to humans.

In the middle of the rainforest. There's a sense of immediacy to a documentary.

This time. Zhou Yun squatted down. Pinch a handful of dirt on the ground. The soil is black soil. Black soil is not naturally formed. It's artificial. People live in this area. Its domestic waste fertilizes the local soil, forming the black soil unique to the Amazon rainforest.

In the very ancient times. In the Amazon rainforest, prehistoric cultures were well developed. At its peak, the population reached more than 50 million. They grow crops, fruits, a well-developed land transport management system, forming a wide variety of living quarters. We know too little about the planet. We know too little about the Amazon rainforest. This area has a high degree of black soil.

Zhou Yun searched the neighborhood. The site of habitation was discovered.

Their domesticated crops were rewilded.

The fruit trees they planted turned into wild fruits.

Zhou Yun discovered an orchard covering an area of 10 square kilometers.

Zhou Yun found two crops.

A legume.

A plant with a root system. Kind of like ginseng. Fat rhizomes.

Zhou Yun collected the beans. Plant seeds.

In the orchard.

Found 3 kinds of fruits.

An abalone nut tree.

A dark red. Fruits like bananas.

A huge fruit. Grow on the trunk of a tree.

Zhou Yun collected several kinds of fruits.

In the live broadcast room.

"I suddenly thought of reticulated melons. and the four-sided fruit. It was brought out of the Amazon rainforest by Zhou Yun. Reticulated melons are now grown on farms all over the world. Become a common fruit. The four-petal prismatic fruit seeds are strictly kept by Ruifeng Farm. 80G canned four-petal fruit powder is sold for 88 yuan a bottle in the supermarket. This year, Ruifeng Farm has expanded the planting area of the four-petal fruit. 168.4 million cans were produced. It brings huge income to Zhouyun. ”

"Yes. There are also lantern scorpion tail peppers. It is now cultivated all over the world. ”

Zhou Yun obtained two more crop seeds here. Not counting abalone nuts. There are two types of fruits. ”

"His achievements as an explorer are very great. “

.......

Zhou Yun searched again. After confirming that there are no omissions. Zhou Yun left here.

......

Afternoon.

In a dry pond.

Zhou Yun found a small puddle.

More than two dozen piranhas were trapped in the small puddle.

If only in a few days.

This puddle has also dried up.

They can only be dried as fish.

Piranhas have sharp teeth. It is the most dangerous creature in the Amazon. Not one of them. Piranhas are known for their ferocity. Commonly known as the wolf clan in the water. Can smell blood. The sense of smell is more sensitive than that of a shark. It can sense the fluctuations of the water flow, and its attack is sawtooth. Tear and cut like a surgeon's scalpel and tear the flesh off. One bite can take 16 cubic centimeters of meat. A wounded and bleeding man falls overboard and is attacked by a group of piranhas. In a few minutes, only one skeleton remained.

Zhou Yun knew one thing. In the Amazon basin, an ancient civilization that predates the Inca civilization is called the Acre civilization, which was a slave civilization.

There were a lot of slaves. The Akha punished slaves. It's very cruel. Slaves were also very afraid. The Aka cut a wound on the slave, made it bleed, and then pushed it into a river full of piranhas, and then, smelling the blood, the piranhas gnawed the slave into a skeleton. It only takes a few minutes. After the loss of the Acre civilization. Then there was the Inca civilization. The Inca civilization was also wiped out by Pizarro.

The piranha is trapped in a puddle with nowhere to escape.

Zhou Yun caught 26 piranhas. These piranhas have bright red bellies. It is a red ascites water tiger. or red-bellied serrated carp. It is one of the most ferocious piranhas.

"Dinner has been served. Zhou Yun said.

In the rainforest. No animal will starve to death. There is no reason why the weekly games will be hungry.

Zhou Yun left the pond.

Continue to advance through the jungle.

In the rainforest, there are always surprises.

For example, the tree in front of Zhou Yun.

It looks like an ordinary tree.

However, this tree is worth a suite in Beijing, Shanghai and Guangzhou.

Of course, if it can be cut down and shipped out.

It's extremely difficult.

Zhou Yun said, "This tree is called serpentine. The Internet fools you every day. I won't fool you either. This tree is cut down if it can be transported out. It is worth a suite in Beijing, Shanghai and Guangzhou. More than 3 million for a suite.

Serpentine wood, also called eel wood. It grows in the primeval jungle of the Amazon basin and is seen in terms of the density, color and structural density of the wood. It is better than red sour branch wood.

Compared to red sandalwood. Although there is no red sandalwood, ten sandalwood and nine emptiness. However, serpentine wood can be used as a commercial timber heartwood, and the yield rate is about 10%. So, the price of serpentine wood is very expensive.

In the international market, prices are based on weight.

The high density, hardness and unique pattern of serpentine wood make it the most suitable raw material in the world for making baroque bows.

A French BASS bow made of serpentine wood and silver inlays costs up to $3,100. Walking sticks made of serpentine wood were also a luxury for the wealthy,...... Some indigenous people from the Amazon jungle, usually in groups of 5 to 8 people, go into the mountains in search of serpentine wood. Then, felled, artificially transported out of the jungle. ”

......

Twilight.

Zhou Yun chooses a campsite.

An open and flat place.

Zhou Yun actually found that there was a swamp not far away.

Zhou Yun took the aluminum lunch box and carried the piranha with a straw rope to the edge of the swamp.

In a small puddle.

Zhou Yun disposed of the piranha.

Remove the head. Remove the internal organs.

Under the swampy mud. Moved.

Zhou Yun didn't notice.

Suddenly, under the mud, a huge tentacle rolled up. It's an octopus's tentacles. A tentacle is the size of a bucket. Caught up in Zhou Yun. I rolled up the week. Roll into the air at a height of 4,5 meters.

In the live broadcast room.

“。。。。。 “

“！！！”

Netizens all over the world who watched the live broadcast saw this scene. The mouth is wide open. You can stuff an apple. Hold the grass. Depend on. Giant swamp octopus. Netizens all over the world held their breath and swallowed their hands. Keep your eyes glued to your phone screen. This swamp octopus has the immediate visual feel of Pirates of the Caribbean 3 Octopus.

Sure enough, we know too little about the Earth's secrets.

We also know too little about the secrets of the Amazon rainforest.

Python. Swamp octopus.

Zhou Yun didn't panic, and reached out to pull out the blue dagger. When the tentacles are cut, the tentacles are cut in half. Swamp octopus eats pain. Nerves also can't control the tentacle endings.

The tentacles let go of Zhou Yun. Zhou Yun fell into the swamp. The swamp will trap people in it. Zhou Yun rolled his body and rolled to the shore. A tentacle rolled towards Zhouyun. Zhou Yun hugged the tentacles. The cells in the body boil and burn. Every cell vibrates. Zhou used his strength to pull out. Pull the gigantic octopus out of the swamp.

Live room.

Netizens widened their eyes. Freeze the scene.

"Zhou Yun, is he practicing? “
