Chapter 866 Compound Eyes
After a whole day, Joan's mentality has undergone a subtle change.
At this moment, he no longer thought that being infected with "worm disease" was an unfortunate experience, but instead regarded it as a godsend opportunity, which gave him the opportunity to experience and study this supernatural disease by himself, saving him the trouble of finding patient samples.
If the truth is told, Audrey will definitely help him cure the disease, and there will be no such convenient conditions to study "worm disease" in the future.
Compared with his own health, Qiao An cares more about exploring the mystery of "worm disease".
He knew that his fanatical curiosity was beyond the scope of reason. But he couldn't help it, he couldn't restrain his thirst for knowledge.
"I'm fine. Recently, I've been busy collecting information about 'worm-like people' and plan to write a paper on this topic."
Joan didn't dare to look directly into Audrey's eyes, and reluctantly found an excuse to evade it.
Audrey knew that Joan had written a thesis on arachnids. Not long ago, he was attacked by worms in Bailun Mountain. He became interested in those half-human, half-worm monsters, and planned to study them in depth, which was completely in line with his usual habits. His style is not worth making a fuss about.
Joan had a hasty dinner, bid farewell to the Zion siblings, and returned to her bedroom on the second floor.
He locked the door, immediately transformed into a giant bee, and compared the copied documents to examine his own insect characteristics one by one.
There are two pairs of membranous wings and six pairs of arthropods. Qiao An has carefully observed them in the morning, and the organ that will be studied next is the huge pair of compound eyes.
Qiao An found that although his compound eyes were very large, and the thousands of small eye surfaces that make up the compound eyes could be imaged individually, overall his eyesight was not good.
In the form of a giant bee, the world in Joan's eyes seems to be composed of countless mosaic colored bricks. The general outline is the same, but the details are very vague.
In addition, this pair of compound eyes also has the problem of "myopia".
There are many books on the bedroom bookshelves, some with titles and authors printed on the spines.
In the human form, Joan could read the writing on the spine of the book from fifteen feet away, but in the giant bee form, he had to walk within ten feet of the bookshelf to barely make out the same writing.
Myopia, blur, these two shortcomings are not unique to giant bees.
According to the information he consulted today, the compound eyes of most insects have the same shortcoming.
One literature states that dragonflies have a field of vision of only 10 to 20 feet, and flies have even worse vision, becoming almost invisible to objects more than 5 feet away.
The general severe myopia, coupled with the mosaic-like clarity, it is no wonder that the flying insects that break into the room keep hitting the glass windows when they try to escape.
The compound eyes of insects can only vaguely see the scene outside the window, but they can't realize that there is a layer of transparent glass in front of them until they bump into it.
Of course, the compound eyes of insects are not all shortcomings, otherwise they would not have survived the long evolutionary process to this day.
In fact, the compound eyes of insects are the product of evolution to adapt to the environment.
Although it is not far enough to see, the field of view is wide enough, and the horizontal viewing angle is as wide as 240 degrees.
In contrast, the horizontal field of view of the human eye is usually around 120 degrees, only half that of compound eyes.
In addition, although the resolution of compound eyes is not high, it is very laborious to observe still life, but it is strong in "dynamic capture", especially good at locking high-speed moving targets.
Joan just used these statements on paper as a reference. Is it practical for him?
He didn't want to make hasty conclusions before experimenting with it himself.
In order to test compound eye vision more conveniently, Joan changed from a giant bee form to a "hybrid" form that is half human and half bee.
In this form, he retained the human torso and limbs, freeing up his hands to record experimental data. He also had a pair of compound eyes, and the strange eyeball behind his neck also remained the same as before.
In addition to having stronger dark vision, the imaging method of the strange eyeball is no different from that of normal human eyes.
In this way, in the beeman form, Joan has both insect and human eyes, which is just right for a control test.
In the beeman form, Joan's vocal cords can work normally, and speaking and chanting spells are not hindered.
Using a 0-ring trick "Dancing Lights", he created four candle-like magical light balls out of thin air, and ordered these light balls to move randomly at high speed in the air.
Joan turned his back first, and observed the ball of light flying in the air with the eyeball on the back of his neck, feeling dazzled.
With all his concentration, he could barely trace the trajectory of one of the balls of light, but when all the balls of light were mixed together, and then bounced in different directions at high speed, he couldn't tell which ball of light was the one he was tracking just now target.
After observing for two minutes, Qiao An was dizzy from the high-speed balls of light moving irregularly, and had to close his eyes to take a break.
After the dizziness and nausea subsided, Joan turned to face the ball of light flying in the air and observed it with compound eyes. The feeling was immediately different, as if the door to a new world had opened.
The high-speed light ball that human eyes can't track is changed to the perspective of compound eyes, and the movement speed of the light ball becomes very slow, like four small glowing snails, crawling around in the air.
Qiao An turned the huge compound eyes, thousands of small hexagonal eye surfaces, refracting magnificent luster of different colors, like a rotating kaleidoscope, taking a panoramic view of the moving trajectories of the four light spheres, and seeing clearly .
Joan nodded in satisfaction, raised his hand and snapped his fingers, the movement speed of the remote control light ball was halved, and another set of control tests was conducted.
In this way, five sets of control tests were repeated until the speed of the light ball dropped to the point where the human eye can clearly capture it.
Qiao An sorted out the experimental data, and after a little comparison, he found that the human eye can only see clearly 20 to 30 frames per second at most, but the compound eyes can easily capture high-speed images of more than 300 frames per second, and the dynamic vision is equivalent to human Ten times the size of the eye!
With such developed dynamic vision, it is no wonder that flying insects such as dragonflies can fly at high speed while avoiding obstacles that suddenly appear in front of them, or catch prey flying at the same high speed.
After testing the compound eyes, Joan plans to confirm a crucial detail, which is to examine whether he has bee needles after he becomes a giant bee.
The bee needle is actually a specialization of the fallopian tube.
Drones don't have stingers, and they certainly don't sting.
Different bees have different structures of bee needles.
For example, in bees, the tail needle has barbs, and the barbs are connected to organs including poisonous glands.
After a bee stings a person, the barb will sink into the human body, and the bee needle will inject bee venom into the opponent's body under the action of osmotic pressure, causing severe pain.
If the stung person struggles violently and shakes off the bee, the barbed tail needle will get stuck in the bee's body, break away from the bee's abdomen, and tear off the internal organs.
While stinging others, you will die yourself. The price that bees pay for this blow can be described as extremely tragic.
