The picture projected on the wall gradually became clear. It was a fish!
Narration: sturgeon is one of the earliest vertebrates in the world. It existed as early as the Triassic more than 200 million years ago and is called the living fossil.
Sturgeon is a kind of swimming fish against the water. Every summer and autumn, groups of sturgeon return to the source, spawning and breeding. Wusuli River is one of their natural production beds.
With the introduction of the narrator, the picture also became a large group of sturgeons, swimming back to the estuary from the sea, upstream.
All of them were very surprised -
I thought that William had gathered them together mysteriously, and there must be some big secret to be announced. Unexpectedly, there was a science and education film?
All of you here are tyrants. If you were not a little afraid of William, or for money's sake, you would have overturned the table.
Karov, who claimed to be a traitor, snorted bitterly.
This guy has yellow eyes and a big beard. He is very strong and looks like a big bear.
From his appearance and name, he should be a Russian, and from his Mandarin, which is very rich in Northeast cavity, it is likely that he grew up by the river, so he is very familiar with this kind of thing. So he didn't have much patience to watch any more. He waved his two hairy hands and grabbed the steak. He took a big bite and didn't even lift his head.
In addition to him, fan Chong, a strong man who is known as the nine fingers lock Han River, as well as the twin river big fish who are smoking dry cigarettes, are not interested in the river small fish, and their faces show some disdain.
From their names, we can see that they are all ancestors who are used to river food.
In the clash of cups and plates, the documentary continued to play, recounting the whole process of sturgeon spawning against the current and returning to the sea in a very detailed way, and then suddenly the conversation turned: this habit of sturgeon has lasted for hundreds of millions of years, has never changed, but there are a group of other species in this big family
Instead of laying eggs in summer and autumn, they return to the Wusuli River in the winter of each year to lay eggs in the same day.
After decades of tracking records, we finally found a shocking law.
These abnormal sturgeons have a specific spawning period on the second day of February in the Chinese lunar calendar, also known as the day when the Dragon rises.
Since its own record, year after year, it has never stopped, and it has never missed a day!
Hearing this, those patrons finally felt a little strange and looked up in surprise.
The camera keeps flashing the images recorded over the years.
The earliest was 1932, and the latest was last year.
The photos changed from black and white to color, then to dynamic video, recording people from youth to old age, then to children standing on one side, the ship from sailboat to steam, and finally to diesel engine.
People have been changed for generations, and ships have been changed. The tracking record books are all marked with red lines and covered with a full screen.
Next, a Chinese perpetual calendar is flipping rapidly. The months and dates on each red line are different, but the only thing that is the same is that the words "22" are written below.
As we all know, both the Chinese lunar calendar and the western new calendar can be changed year by year. Let alone the spiritless fish. Even people can hardly remember them.
But over the years, this group of sturgeons are all right. It's the right day to lay eggs. I didn't miss it at all. It's weird!
Until then, everyone was intrigued and stared at the screen.
As soon as the picture turned, it became dark, and there was a faint white light shining in the middle, just like a flashlight that was about to run out of energy shining in the vast night.
The sound in the camera continues to explain: after tracking, these strange sturgeons are not only laying their eggs on a very strange date, but also the place where they laid their eggs is a mystery.
Other sturgeons are only produced in the crevices at the bottom of the river, but they have been swimming towards the deepest part of the Wusuli River.
The average water depth of the Wusuli River is only two to five meters, but they are miraculously penetrated through a deep ditch at the bottom of the river.
This image was taken with the sturgeon drilling into the deep ditch, more than 70 meters underground.
No one knows where the deep ditch leads to? And how it came into being.
The group of sturgeons are still swimming, and the camera device that follows should be tied to one of them, moving rapidly with the swimming fish. Under the collision of fish, the camera keeps shaking.
This area of water is extraordinarily turbid, so high times of light can only see the surrounding area of about 20 cm.
As the fish gradually went deeper and deeper, the scene in front of us became more and more blurred. At last, we could only see a small piece of palms. It seemed that the water around us was not water, but thick ink, which was not transparent at all.
At this time, I didn't understand the sound, only the rustle of the machine, occasionally mixed with the sound of fish waves.Suddenly, a knife appeared in the blurred halo when the picture turned!
Although the image is very fuzzy, it can still be seen that it is a long pole broadsword with a bright head and a very simple pattern engraved on the pole.
Sturgeon continued to swim forward, and a piece of white bone appeared at the bottom of the river. The skin and flesh on the white bone had rotted, or had been eaten up by something, leaving only a piece of black hair. Those two black eye sockets are full of green algae, like staring at a pair of green eyes.
There are many white bones, splattering all over the ground, stretching out from the mud of unknown thickness, high and low as the white stone of the river.
Sturgeon with the camera to continue to move forward, full foot swimming for five or six minutes, there are still bones from the fall of scattered everywhere.
Slowly, the mud disappeared. Instead, it was a piece of bluestone with patterns engraved on its surface. These bluestones are extremely huge. Judging from the speed of the fish, they are at least two meters long!
About a dozen bluestone slabs have been swam by, and some extremely huge pillars appear vaguely.
Because the fish just swam by from one side, it couldn't see completely, so it couldn't judge how thick the column was. However, it can be seen that there are some very strange patterns and totems carved on the column.
At this time, a huge step appeared in front, which was covered with green algae.
The stone platform is extremely wide, about two feet wide and three feet high.
"Roar..."
Suddenly, a roar came out, like a prehistoric beast hidden in the deep of Wusuli River.
