Nile tilapia does not swim very fast, but it is also much faster than Yang Wu's.

They didn't see where Yang Wu was, but they felt the fluctuations of the current, and their developed body perception allowed them to judge the size of the object and avoid it in advance.

In fact, fish are affected by the degree of evolution, living environment, and lifestyle, and their eyesight cannot be compared with humans, even the sea bream, which has the strongest eyesight among fish, its eyesight cannot be compared with humans in terms of distance and width.

The eyesight of a fish is roughly proportional to the size of the eyeball, and the larger the eyeball, the stronger the eyesight.

Conversely, fish with smaller eyeballs have worse eyesight.

Living in the water for a long time allows the fish's eyes to form a special set of structures and methods of adjustment.

When we eat fish, we will see that each fish has two small white balls in its eyes, which are the lens of the fish's eyes, which are often referred to as the fish's eyes.

The lens of fish is inelastic and does not thicken or thin like the lens of the human eye.

As a result, fish can only see objects at different distances by adjusting the distance between the lens and the retina.

This structure, which regulates the distance between the lens and the retina, is called the sickle process.

And because the lens of fish is spherical, the light reflected by objects that are too far away can only fall in front of the retina through the refraction of the lens, so that they cannot see objects too far away.

In addition, in water, due to the influence of microorganisms, suspended solids, and water layers, light transmission is blocked, and it is not possible to see as far as in the air.

At the same time, the fish does not have to look far in the water, so the fish's eye structure is suitable for seeing near objects, that is, the fish is short-sighted.

For example, freshwater salmon can only see objects at a distance of 30~40 cm in clear and transparent water, and can only see objects at a distance of 10~12 meters after the adjustment of the sickle-shaped process.

As for the perception of color, fish and humans also have different tendencies.

Humans are more sensitive to red and yellow, but fish are more sensitive to water and green.

This is because the water layer absorbs most of the light and only allows the water color to pass through, so in the air, it feels red when it sees red, but in the thick layer of water, it becomes almost black. The hook used to catch stream fish is designed to deal with fish whose eyesight is underdeveloped and will mistake the hook for an insect in the water.

Although the eyes of the fish cannot see far in the water, because the water has the effect of refracting light, the fish can not only see things in the air, but also see objects closer than the actual distance, so that the fish can detect the shore and especially the active people earlier, so that they can swim away quickly.

Fish can wrestle with currents in the sea where they can't see their fingers, and can accurately spot obstacles and determine the right direction.

These skills are very peculiar.

Scientific studies have shown that these behaviors are done by fish using lateral lines on their bodies.

The lateral line is a special sensory organ of fish, which is the "sixth sense" system of fish.

It can be seen from the outside of the fish's body. This is the line of many small holes arranged on both sides of the fish's body.

These small holes are called lateral line tube holes, and the small holes are distributed on some scales, and the bottom of the small holes communicate with each other to form a long tube, which is called a lateral line tube.

The tube is filled with mucus, and the stimulation of the external water flow is transmitted to the sensory cells in the lateral line tube through the lateral line tube hole on the scale, which can produce excitement, and the excitement is transmitted to the brain through the nerve, and the water flow sensation can be produced.

Fish can sense the magnitude of water pressure, the direction of current, the speed of current, the position of objects in the water, and various other changes through the measurement line.

Yang Wu opened his eyes and saw not very far in the water, and after opening his eyes for a long time, it would become sour and painful.

On a whim, he mobilized the life source in the dantian to strengthen his eyes.

With the integration of the origin of life, Yang Wu found that his eyes, which had been swollen and painful because of opening his eyes underwater, suddenly relaxed.

He felt that his eyes were cool, the structure of the cornea had also changed slightly, the water barrier effect was significantly strengthened, and the pressure resistance of the eyeballs was also significantly improved.

This undoubtedly made Yang Wu excited, the success of this experiment not only strengthened the eyes, but also verified some of Yang Wu's ideas!

It turns out that the feasibility of the origin of life is so broad!

As a result:

Is it possible to store more oxygen after the lungs are strengthened, or can the water be filtered and breathed underwater?!

Will the brain become smarter after it is strengthened, so that it will be easier to develop consciousness in the future?

Ever since he fought with the king cobra, Yang Wu also thought about it, he had obviously seen the king cobra's attack trajectory, why couldn't he control his body and dodge it at that time?

Maybe it's because the brain doesn't have enough control over the body!

Although lions are larger than humans, they have much smaller brain capacity than humans.

Even if Yang Wu's body is a lion, his soul is still a human soul, so the lion's brain is not enough to contain Yang Wu's soul.

Although Yang Wu didn't feel any discomfort after traveling for so long, it was just because the strength of the brain was enough, but the capacity was far from enough!

Yang Wu's human soul consciousness can detect the attack trajectory and speed of the king cobra, but because the brain capacity of the lion body is not enough, it cannot react so quickly, so it will make Yang Wu have the illusion that his body is uncoordinated!

In fact, it's not that it's uncoordinated, it's still that the brain capacity is insufficient.

This experiment made Yang Wu extremely excited! This is a stage of cognitive progress on the origin of life!

Yang Wu's next plan is to hunt prey on a large scale and accumulate a large amount of life origin, so as to better develop the role of life origin.

As for the monstrous killings caused in this process, it was really not something that Yang Wu could consider.

Natural selection, survival of the fittest!

This is the law! This is the rule!

In order to live, in order to live better, in order to become stronger!

Yang Wu collected his thoughts a little, this matter can be put on the agenda, but now it is better to catch some Nile tilapia to fill his stomach.

Nile tilapia sensed Yang Wu and quickly escaped in advance, which made Yang Wu pounce with great interest.

Of course, he is not reconciled, the reason why people become the masters of all things is because they can use their brains!

Yang Wu was a standard normal human before his death, and it would be a shame if he couldn't even catch a fish.

Although as a lion, Yang Wu has a lot of tools that he can't use, but the routines can be used at any time.

In the position of Lake Victoria near the lake, the water is still relatively shallow, about 20 meters.
