From the Island Owner to the King

For example, Professor Dai Jixian, an academician of the Chinese Academy of Sciences, the internationally renowned ornithologist Calvin Wiesenke, the internationally renowned biologist, Chen Rui's best friend, Earl Hill, etc., because Chen Rui is often in the .q/q group Send some pictures of novel biological species. In order to obtain the latest first-hand information, there are many biologists from all over the world who have joined this group.

As soon as the picture of the North American passenger pigeon came out, it shocked all the biologists in the q.q group. Professor Dai Jixian was so excited that he could not wait to fly from Yanjing to Daqingshan immediately. Calvin Wiesenke excitedly asked his assistant to book a flight ticket, and he wanted to rush immediately. When he went to China, Earl Hill wanted to contact Chen Rui immediately. The expedition team of Li Jiayi's grandfather Li Haichuan became even bigger. An American biological team boarded a plane to China,... .., biologists around the world can't wait to see the North American passenger pigeon, the famous bird long identified as extinct.

------------

Chen Rui and Li Jiayi spent their first night in Daqingshan.

The next day, the two of them got up early in the morning. The air in the forest was very fresh, the sun had not yet come out, the dew was heavy, and the air was very humid. Jungle Morning Song.

After the two had washed a little in the creek, Li Jiayi received a call that the expedition had entered the mountain and would arrive here at about 9:30 in the morning, about 2 hours from now.

The two of them didn't go anywhere, just waiting for the delegation here.

I heard that there are a lot of people in the expedition, there are dozens of people. In addition to the Chinese biologists, there is also an expedition from the United States that arrived overnight. It is said that there are some official backgrounds in the United States. Many biologists from all over the world have entered Daqingshan one after another, looking for North American passenger pigeons in Daqingshan.

At about 10:00, Chen Rui and Li Jiayi waited for the delegation led by Li Haichuan. There are more than 40 people, including famous Chinese biology professors, foreign biologists who speak English, and their assistants. Carrying a large backpack, carrying camera equipment, panting and beard, sweating on his face, he has entered the mountain since the dawn of the morning. Up to now, climbing the rugged Daqingshan mountain road is quite hard.

"Hello Ruichen, I'm Misleton Denver from Harvard University."

"Hello, Professor Miselton."

"Hello, Professor Dai."

......

After everyone introduced each other.

"Everyone, rest first, and wait for me to take you to find the giant salamander and the passenger pigeon.

"

"It is a very rugged and steep mountain with deep and dense forests. It can be said that it is a deep mountain and an old forest. It is no wonder that the Daqingshan giant panda subspecies, giant salamander and passenger pigeon have been found in this mountain. If it is confirmed that the North American passenger pigeon is indeed found in Daqingshan. If there is a trail, I will apply to the state for a nature reserve."

"I have an old friend in the United States. I heard that a passenger pigeon was found in Daqingshan. He has called me 4 or 5 times to confirm whether the passenger pigeon was really found."

......

Everyone rested and drank some water. After eating something, I can't wait to start.

Chen Rui took everyone to the cave upstream of the stream.

"We also roughly counted the giant salamanders that Jiayi and I found here. There are about 30,000 to 35,000."

Scientists in China took out their cameras and started taking pictures of giant salamanders in the stream. And fish out a few, put in a tank.

Under the guidance of Chen Rui, scientists found the largest giant salamander in a cave. After measuring, it was learned that this giant salamander was 2 meters long. Weighing 75 kilograms, he is already 150 years old, setting a new Guinness World Record for 'stupid'.

It seems that biologists from the United States are not very interested in giant salamanders. They keep asking Chen Rui about the process of discovering North American passenger pigeons, and they show great interest in North American passenger pigeons.

Around noon, the research on giant salamanders came to an end.

In the afternoon, Chen Rui took everyone into the jungle.

About two hours later, arrived in the woods where the North American passenger pigeon was found yesterday.

"Yesterday, we found the trace of the passenger pigeon here." Chen Rui pointed to the dense forest in front, "The passenger pigeon stayed in this forest for about 4 or 5 minutes, then flew away and headed over there. Fly in that direction.

"Thank you very much." Miselton Denver said to Chen Rui, "We want to stop here for a while."

"Can."

Everyone entered the woods and found some feathers and feces left by the passenger pigeons on the ground and put them in bags. The discovery of the passenger pigeon feathers and feces gave the scientific expedition team more confidence to find the passenger pigeons.

Look in the direction the passenger pigeon flew away yesterday.

While walking, Chen Rui suddenly stopped, turned his head and said, "Everyone, stop and step back, I found something."

"Jiayi, give me the trekking pole."

Li Jiayi handed Chen Rui the trekking pole in his hand.

Chen Rui took the trekking pole and slowly moved the trekking pole into the grass. Suddenly, he pressed down on a triangular snake head.

It turned out that there was a poisonous snake hidden in the grass ahead.

The head of the venomous snake is triangular, shaped like a soldering iron, the tail is white, and the whole body is dark brown, interspersed with very small yellow-green or rust-colored spots, forming a fine mesh impression, part of the back scale is yellow-green, forming a Aggregate to form lichen-like spots, equidistant from dark brown, running through the tail of the body, ....

"This is the Mangshan soldering iron head." A Chinese biologist in the delegation said with some surprises.

Chen Rui knows him, from Yanjing, his name is Li Qingming, a famous Chinese biologist, herpetologist, and ornithologist, who has a very deep research on snakes and birds. Pigeon, can't wait to follow the delegation.

Li Qingming went on to say, "This is the largest poisonous snake in the world. Unlike other pythons, Mangshan Ironhead belongs to a giant poisonous snake, belonging to the Viperidae family. The vicious giant pit viper, the strange rattlesnake, and the coquettish bamboo leaf green snake are all its cousins. .

Due to the large size of the Mangshan soldering iron head and the large amount of venom secretion, once bitten, its snake venom will rapidly attack the human body with the blood, and in a very short period of time, it will cause death,.......

Most of these snakes are distributed in the southern Mangshan Lake (), in the local Mangshan Mountain, Mangshan Iron Head is considered to be the direct descendant of the legendary Fufuxi Nuwa, 'Xiaoqinglong', ..., Mangshan In addition to the distribution of soldering iron heads in the forest area of ​​Nanmang Mountain in Lake (), there are also distribution in the north of Lake () and the east of Guang (), the number is rare, only wild ones are found in China, and there are only about 300 to 500 in the whole of China. The number is smaller than that of giant pandas, and it is called 'the giant panda in the snake kingdom'.

Due to its rarity and scientific research value, it was fired for more than 1 million yuan on the black market. It is a very unexpected surprise to find the Mangshan soldering iron head here. "

Everyone took out the camera and took a few sets of photos, and then let Chen Rui free.

After the discovery of Mangshan Iron Head, everyone's interest was obviously high. Daqingshan is really a treasure trove of biological species, subspecies giant panda, giant salamander, Mangshan Iron Head, and the most cherished North American passenger pigeon,... ., the deeper you go into Daqingshan, the more exotic creatures will be discovered, and everyone is looking forward to it.

Although Chen Rui discovered the North American passenger pigeon in the forest yesterday, however, a 'brigade' in the passenger pigeon shows that the bird's habits are not like many terrestrial creatures, which are limited to living in a fixed place. The North American passenger pigeon It has to fly everywhere, so it is very difficult to find North American passenger pigeons in Daqingshan, and you have to try your luck. It is estimated that everyone is prepared for this.

More than 40 people stayed in Daqing Mountain for 3 days, and they have gone deep into Daqing Mountain, and still no trace of North American passenger pigeons has been found.

However, many rare species were discovered, such as metasequoia, wild ginkgo trees, dove trees, clouded leopards, macaques, red pandas, etc., as well as a whole yew forest, which surprised everyone in the delegation.

You must know that the yew is very rare and precious. The yew is an ancient tree species left over from the Quaternary glaciers. It has a history of 2.5 million years on the earth. Due to the slow growth rate of the yew, from the seed to the ground Trees, which take 100 to 250 years, are very few in number. Taxus yew is called a 'national treasure' in 42 countries in the world with yew trees.

Taxus has also become a popular 'star' in the plant world in recent years, because it can extract paclitaxel.

Paclitaxel is a worldwide recognized anticancer and anticancer agent.

In 1971, two chemists in the United States successfully isolated a substance from the trunk of the yew tree, named paclitaxel.

In 1992, paclitaxel was officially approved by the US Food and Drug Administration (FDA).

In China, in the summer of 1992, the first wave of yew bark wars started in the northwest region of Yunnan (), southern Yunnan Province, and a large number of businessmen flocked to forest areas to purchase yew bark,  …

In the United States since 1992, paclitaxel has been hailed as one of the three first-choice anti-cancer drugs in clinical use, and its value has risen year by year. American manufacturers with patents have made the price of paclitaxel higher and higher, reaching three or four million US dollars per kilogram, ..., paclitaxel has become the drug with the most investment potential, and paclitaxel investment has emerged around the world. hot.

The content of paclitaxel produced in China is above 98%, and the export price is generally 800 yuan / gram. In foreign countries, each gram of paclitaxel is made into 33 grams of injection, each containing about 30 ml of paclitaxel, and the anti-selling in my country is about 2,500 yuan / per gram. In RMB, each gram of imported paclitaxel is equivalent to paying RMB 80,000, which is more than 600 times the price of gold. (To be continued.)
