Starting from Zero

The flying bird is not a product of natural evolution, but one of the ultimate representatives of alchemical technology-a synthetic beast, which means that it is an artificial creature.

As a man-made creature, the bird has a very special body structure, and its own gas propulsion system is already a strange existence in the biological world, but this is not all his alternatives.

Because of the gas jet flight method, the flying speed of the bird is very fast, and at this speed, the vision is obviously unable to meet the requirements, because the vision is too much affected by environmental factors such as obstacles If the field of vision is not wide enough in areas with complex terrain, there is absolutely no way to avoid obstacles at the speed of a bird.

In order to cope with the information collection requirements of its own high-speed flight ability, the observation organ of the bird is not the eyes on the head, but his entire tail.

Asuka's body structure is actually very different. The posture he uses when flying is actually not the forward flight we are used to, but the backward flight. The sharp three-sided thorn in the forward direction of the bird is actually an extension of his spine, which is the tailbone. As for the short and flat thing behind the bird when it flew, it was actually his head, and his brain was located in this position. However, because Asuka does not have a neck, this part is actually not very obvious. It just slightly protrudes from the body. As for the long streamer at the back, it should actually be Asuka's crown or hair. But this thing is different from hair. It has muscle tissue inside and can move according to the bird's consciousness. When the bird is flying, this thing basically acts as a vertical tail, which can assist in steering.

Because the head is located at the back of the body during flight, the eyesight of a bird is actually very average, and even if the eyesight is good, it is obviously meaningless for a bird that can only fly forward. , After all, you can't see what's in front at this position. Therefore, the real dominant sensory of Asuka is actually the triangular thorn that is located up ahead in the direction of flight. This thing looks like a weapon, but it's actually an antenna.

We all know that there are a large number of nerve bundles in the vertebrae of vertebrates, which is the same important nerve center area as the brain, and the cudal vertebrae of birds, which is the end position of the spinal nerve, has a larger Nerve center. This hub is actually an accessory brain. Unlike the brain, this accessory brain does not have abstract thinking capabilities, nor can it control any organs on the body. The actual function of this accessory brain is similar to an electromagnetic transmitter and a supporting translator.

According to the instructions of the brain, this accessory brain uses a group of special cells in the body to generate high-voltage currents, and then the highly metalized cudal vertebrae acts as an antenna, emitting strong currents in the form of electromagnetic pulses. . At the same time, this cudal vertebrae is also responsible for receiving the echo signal after transmitting the signal. When the caudal vertebrae receives the echo, it will pass the signal to the accessory brain, and the accessory brain will filter and analyze the echo signal, first remove irrelevant signals and signals from other similar species, and then separate the signals sent by itself. And decode it. Based on this group of echo signals, the accessory brain can create a three-dimensional scan of the surrounding environment and transmit it to the brain.

To put it simply, this accessory brain, the group of power-generating cells, and the caudal vertebrae, the three are combined into one—radar. Yes, it is a radar, a biological radar.

Relying on this set of bio-radars, birds can completely ignore the influence of light and fly at will in the dark or daytime. At the same time, because the diffraction ability of electromagnetic waves far exceeds that of light waves, and the penetrating power of electromagnetic waves is also better than broadcasting, bio-radars actually have certain steering and penetrating capabilities. This is why Asuka can fly at high speed in a narrow underpass with many bends without hitting the wall, because he can see the next bend and the route after it before he gets close to the bend, so he can plan ahead. Flight trajectory, and if you look at the road with your eyes, you simply don’t know what the route behind you will be like before turning the curve, but it’s too late to look at the road after you turn around. Therefore, the role of this group of bio-radars is more useful than the eyes in most cases, especially in high-speed flight mode.

When I shared all the surrounding environment information scanned by Asuka's bio-radar into my head, all my pets were equivalent to seeing the surrounding environment simultaneously.

This is a very special information picture, because unlike the eyes, the radar signal cannot display colors, so what appears in our minds is actually a group of completely gray levels to display The picture is just like a sketch. Of course, the fineness is completely incomparable. At the same time, apart from the lack of color, this picture is not continuous. In fact, the picture we see has been flickering, and it is constantly updated around flying birds, but this refresh rate is very fast, basically it can be refreshed hundreds of times every second, so although we know it is flickering, but In fact, there is no abnormal feeling. And in this picture, we quickly discovered our goal.
