The picture projected on the wall gradually became clearer, it was a fish!

The narrator said: Sturgeon is one of the earliest existing vertebrates in the world. It has existed since the Triassic period more than 200 million years ago and is known as a contemporary living fossil.

Sturgeon is a fish circling against the current. Every summer and autumn, it returns to its source in groups to lay eggs and reproduce. The Ussuri River is one of their natural breeding beds.

With the introduction of the narrator, the picture also turned into a large group of sturgeons, swam back from the sea to the estuary, and went upstream.

Everyone was extremely surprised-

I thought that William gathered them together mysteriously and there must be some great secret to be announced, but I didn’t expect that it would be a science and education film?

Everyone here is the overlord of the side, the powerful and powerful figure in the Yin world. If it weren't for the slightest fear of William, or because of the money, they would have probably overturned the table.

Karov, who claimed to be a boatman, snorted coldly in dissatisfaction.

This guy has a yellow-eyed beard, and has a very strong physique. He looks like a big bear.

Judging from his appearance and name, he should be a Russian, and from his extremely rich Northeast Mandarin, he is likely to have grown up by the river, so he is naturally very familiar with this kind of thing. Therefore, he didn't have much patience to read it anymore. He grabbed the steak with his two big hairy hands, and ate it in big mouthfuls, without even raising his head.

In addition to him, Fan Chong, a strong man who is known as the Jiufing Locking Hanjiang, also had the twins Jiang Dayu who smoked dry tobacco. Jiang Xiaoyu was not interested, and his face showed some disdain.

It can be heard from the names of them that they are all ancestors who are used to eating Jianghe rice.

As the sound of cups and plates colliding, the documentary continued to play, and the entire sturgeon was spawned against the current and then brought back the sea in a very detailed manner. After a sudden change of the topic: This habit of sturgeons has been going on for hundreds of millions of years and has never changed, but there is a group of alternatives in this big family...

They do not lay eggs in summer and autumn, but they return to the Ussuri River to lay eggs every winter, and the spawning period is the same day.

After decades of tracking and recording, a shocking rule was finally discovered.

The specific spawning period of these anti-normal sturgeons is the second day of the second lunar month of the Chinese lunar calendar, which is commonly known as the day when the dragon raises its head.

Since the record has been made, it has been like this every year, never stopped, and I have never missed it for a day!

When they heard this, the guys who were patronizing for food and drink finally felt something was strange and raised their heads in surprise.

Images recorded from previous years are constantly flashing on the camera.

The earliest was in 1932, and the latest was last year.

The photos went from black and white to color, and then turned into dynamic videos. The people who wrote the records went from youth to old age to children who were originally standing aside. The boat also went from sailing to steam, and finally became a diesel engine.

People have been replaced for several generations, and ships have been replaced. All the tracked records are marked with red lines, and a full screen is laid.

Immediately afterwards, a Chinese perpetual calendar flipped rapidly. The months and dates on each red line were different, but the only thing that was the word "22" was written below.

As we all know, whether it is the Chinese lunar calendar or the Western New Calendar, they are changed every year. Not to mention the unspiritual fish, even people are extremely difficult to remember.

But over the years, all of this group of sturgeons have been right at all. They lay eggs on this day, and they didn't miss it. This is a bit weird!

Until this moment, everyone was attracted by interest and stared at the screen with their eyes.

The picture turned and turned black. I saw a faint white light flashing in the middle, like a flashlight that was about to exhaust its energy shining in the vast dark night.

The sound in the camera continued to explain: After tracking, it was found that these strange sturgeons not only had a very strange spawn date, but also had a mystery.

Other sturgeons are only produced in the cracks at the bottom of the river, but they have been swimming towards the deepest part of the Ussuri River.

The average water depth of the Ussuri River is only two to five meters, but they magically penetrated a deep ditch at the bottom of the river.

This image was taken after sturgeons drilled into deep grooves and penetrated more than 70 meters underground.

No one knows where this deep trench leads to? How it was formed.

The group of sturgeons was still swimming constantly. The camera device that followed closely behind should be tied to one of them, moving rapidly with the swimming fish. Under the collision of the fish, the camera kept shaking.

This water area is unusually turbid. When the lights are so high, you can only see a range of about twenty centimeters around you.

As the fish gradually deepened, the scene in front of us became more and more blurry. In the end, we could only see a small piece the size of a palm, as if it was not water, but thick ink around, which could not be illuminated at all.

At this time, there was no sound of explanation, only the rustling sound of the machine, occasionally mixed with the sound of fish waves.

Suddenly, the picture turned and a knife appeared in the blurry halo!

Although the image is very blurry, it can still be seen that it is a long-rod knife with a sharp head and an extremely ancient pattern engraved on the knife rod.

The sturgeon continued to swim forward, and another white bone at the bottom of the river appeared. The flesh on the bones had already rotted, or had been gnawed by something, leaving only a piece of black hair. The two black holes were covered with green algae, as if they were staring at a pair of green eyes.

There were many white bones, piled up all over the ground, stretching out from the silt that was unknown, high and low like white stones in the river.

The sturgeon continued to move forward with the camera and swam for five or six minutes, and there were still white bones scattered everywhere.

Slowly, the mud disappeared, replaced by a bluestone slab with patterns engraved on the slab. These bluestones are extremely huge. Judging from the speed of the swimming fish, they are at least more than two meters long!

After swimming about a dozen bluestone slabs, some extremely huge pillars appeared vaguely.

Because the fish just swam past one side and couldn't see it thoroughly, it was impossible to tell how thick the pillar was. However, you could see that there were also some very strange patterned totems on the pillar.

At this time, a giant staircase appeared in front of him, covered with green algae.

The stone platform is extremely wide, almost two feet wide and about three feet high.

"roar……"

Suddenly, a low roar suddenly came out, as if there was a prehistoric beast hidden deep in the Ussuri River.
