Under the swift flow of the Yuan River, countless underwater creatures have gathered together, as if some force has attracted them.

If the scene of these aquarium creatures gathering is broadcast on the Internet, it will definitely be another uproar.

Not to mention the dense, constantly overlapping and wriggling bodies, which make people's scalps tingle, the size of these animals alone is beyond the scope of human comprehension.

A crayfish can be more than a meter long, this size, who dares to add a "small" word in front of its name; a water snake that can be seen everywhere in the field is also more than ten meters long and the thickness of a football.

You must know that the longest snake that humans have observed in the world so far is only a 14-meter-long reticulated python. The water snake itself is a small snake, and their physiological limits determine that they cannot reach a length of more than ten meters.

But what's going on now, these water snakes more than ten meters long not only appeared, but also abounded, more than ten meters are just the most ordinary body type, more than twenty meters, and it is not for nothing that the water snakes that are taller than a five-story building are not nothing.

Not only crayfish and water snakes, but also fish, turtles, turtles, and all kinds of underwater creatures are like eating catalysts, expanding ten times or dozens of times more than their normal size.

One or two animals with specific growth appear, it can be said to be genetic variation, but thousands, tens of thousands of aquariums have the same changes, and it must not be defined only by genetic variation, after all, we all know that genetic mutation is a small probability event, and there is no one in tens of millions of cases, how can it be possible for underwater organisms in an area to occur on one side.

And this is only a small section of the Yuan River, although the volume of the Yuan River is not small, but it is only a direct flow of the Yangtze River, in front of the main trunk of the Yangtze River, inconspicuous, this small section can gather such a terrifying force, if the outside world is the same, then the world will set off what earth-shaking changes?

At the core where tens of thousands of huge water beasts gathered, there was a black giant snake more than forty meters long, which was lying in front of all the beasts, even if it was motionless, the power of the king of all beasts still did not allow any aquatic creature to provoke.

Its appearance, not that of any recorded snake, with a body length of forty meters and a waist as strong as a bucket, has no doubt that it fits the depiction of a calamity beast in any disaster movie, even if it is not attackable, just walking around the human world is enough to cause unimaginable casualties and property damage.

However, even so, its head was not oval like a python, and the sharp triangular snake head seemed to be piled up brick by brick by the most skilled worker, full of danger.

Even ordinary people know that most snakes with triangular snake heads have this poison, but poisonous snakes and pythons are two completely different categories, and in the process of evolution, one chooses a strong physical fitness and hunts directly by strangulation, and the other chooses a highly poisonous venom to make the prey lose the power to resist.

These two evolutionary cohorts can't say who is superior and who is inferior, after all, they have allowed snakes, this group to multiply and survive, and adapt to the inheritance of snakes under the threat of natural predators.

It's just that these two ways are like two opposite paths, and I've never seen a snake that can do both.

Under the black snake, a bucket-sized hole is bubbling out of the clear water, and it can be seen that this is a secret passage at the bottom of the river, and I don't know that it is connected to the underground river under the water, which has become one of the supplies of the Yuan River.

Of course, this amount of water, even if it keeps gushing out, is just a drop in the bucket for the huge Yuanjiang River, and it is not worth mentioning.

In the invisible world with the naked eye, there are wisps of invisible and substantiated gas, following the trajectory of the water flow, gushing out from under the cave, the big black snake seems to be able to sense the existence of this invisible air flow, his breath and breath, contains a special rhythm, each stroke just fits the frequency of the gushing of the dark cavern below, absorbing all those air currents.

Only some idle air currents were able to escape and be absorbed by the rest of the surrounding water tribes, and once they got into this nameless air flow, it was like taking hormones, and their bodies began to convulse violently, as if they were in great pain, the carapace was broken, and bright red blood overflowed everywhere, staining the river red.

But in the same way, their size is also growing at a rate that is visible to the naked eye, and almost in a breath, many of the aquarium that have been contaminated with breath have increased in size by a meter or two.

It is conceivable that the nameless air flow is the root cause of such changes in the Yuanjiang aquarium.

The point is, just a few missing scraps can make the surrounding water tribe undergo such a big metamorphosis, the cave is guarded by the big black snake, and ninety-nine percent of the nameless air flow has entered its stomach, so how terrifying should the big black snake be?

On the body of the big black snake, the invisible power suddenly lifted, it was the coercion from the ancient high predator, and the thousands of aquatic creatures who were originally guarding the big black snake to taste some soup and water were shocked, and then as if they had encountered the most terrifying devil in their lives, they hurriedly plunged their heads into the sand, trembling, and did not dare to show their faces.

The momentum on the big black snake's body continued to rise, and finally seemed to have reached a critical point, the big black snake opened its eyes suddenly, and its violent and vicious snake pupils erupted with shocking killing intent.

This killing intent, as strong as substance, was suddenly stopped by the trembling bodies of several big turtles that were inadvertently swept by the gaze of the big black snake, and then the dim liquid flowed out from under them, and they were scared to pee.

You know, they are beasts, they have lived in a dangerous natural environment since they were children, and their endurance is far beyond that of humans, but they are still scared by the big black snake's eyes, which shows what kind of pressure the big black snake has caused in their hearts.

"Roar!!" the big black snake raised its head to the sky and roared, and the sound waves stirred up the water waves, and then spread, knowing the distance.

The effect of the invisible air flow finally accumulated to a qualitative moment, when the big black snake roared in the sky, wantonly showing its strength, his huge body from above and below constantly made a crackling sound, like the sound of gunpowder explosion, the aftermath continued, the big black snake's already thick body was elongated again in the sound, growing from forty meters to forty-five meters.

At the same time, on the triangular head of the big black snake, two small packets also appeared silently, as if something was about to grow out of the skin.
