Chapter 866: Compound eyes

Over the course of the day, Joan's mentality changed subtly.
At this moment, he no longer considered infection as an unfortunate encounter, but regarded it as a godsend opportunity, giving him the opportunity to experience and study this supernatural disease firsthand, eliminating the need to find patient samples.
If you tell the truth, Audrey will definitely help him to cure the disease, and there will be no such convenient conditions to study "insecticide" in the future.
Compared with his own health, Joan is more concerned about exploring the mystery of "insectosis".
He knew that his fanatical curiosity was beyond the scope of reason. But he couldn't help curbing the curiosity of knowledge.
"I'm fine. Recently I am busy collecting information about worms, and plan to write a paper on this."
Joan didn't dare to look directly at Audrey's eyes, and barely made an excuse to stifle it.
Audrey knew that Joan had written a paper on arachnids, and was recently attacked by insects in Bailun Mountain. He was interested in those half-human and half-worm monsters. The style is not worth fussing about.
Joan hurriedly ate dinner and quit her sister Zion and returned to her bedroom on the second floor.
He locked the door of the room, immediately transformed into a giant bee, and compared with the transcribed documents, one by one to examine the characteristics of his own insects.
Two pairs of membrane wings and six pairs of arthropods have been carefully observed by Joan in the morning. The next major research is the huge compound eyes.
Joan found that although his compound eyes were large, the thousands of small eye surfaces that make up the compound eyes could be imaged separately, but overall his eyesight was not good.
In the form of a giant bee, the world in Joan's eyes seems to be stitched together by countless mosaic tiles, the general outline is so different, and the details are vague.
In addition, these compound eyes also have "myopia".
There are many books on the bookshelves in the bedrooms, and some books have the title and author printed on the spine.
In human form, Joan can see the text on the spine 15 feet away, and in the form of a giant bee, he must walk within 10 feet of the bookshelf to barely recognize the same text.
Myopia, blur, these two shortcomings are not unique to giant bees.
According to the data he consulted today, the compound eyes of most insects have the same shortcomings.
One document pointed out that the dragonfly's field of vision is only 10 to 20 feet, and the vision of the flies is worse, and objects over 5 feet are almost invisible.
The prevalence of severe myopia, combined with the sharpness of hitting Marsek, it is no wonder that flying insects that break into the room always keep hitting the glass windows when they try to escape.
The insect's compound eyes could only see the scene outside the window indistinctly, but could not perceive a layer of transparent glass in front of him until it hit a head.
Of course, the compound eyes of insects are not all shortcomings, otherwise they will not survive in the long evolutionary process.
In fact, the compound eyes of insects are the evolutionary product of adapting to the environment.
Although it is not far enough to see, the field of view is wide enough and the horizontal viewing angle is up to 240 degrees.
In contrast, the horizontal viewing angle of the human eye is usually around 120 degrees, which is only half of the compound eye.
In addition, although the compound eye is not well-resolved and it is very laborious to observe still life, it focuses on "dynamic capture" and is particularly good at locking high-speed moving targets.
Joan just used these references as a reference. Is it practical to be specific to him?
He didn't want to make a hasty assertion before experimenting.
In order to more easily test compound eyesight, Joan changed from a giant bee form to a half-human half-bee "hybrid" form.
In this form, he retains the human torso and limbs, so that he can free up his hands to record the experimental data, and also has a pair of compound eyes, and the strange eyeball behind the neck also maintains the old appearance.
In addition to having a stronger dark vision, the strange eyeball imaging method is no different from the normal human eye.
In this way, in the form of a bee-man, Joan has both insect and human eyes, which is just a control test.
In the form of a bee, Joan's vocal cords can work normally, and speaking and chanting spells are not hindered.
A 0-ring trick "dance light technique" was used to create four candle-like magic light out of thin air, and these light were ordered to perform high-speed random movements in the air.
Qiao An turned back and observed the light ball flying in the air with the eyeball behind his neck.
He concentrated on it, barely able to track the movement of one of the light balls, but when all the light were mixed together and then bounced off at high speed in different directions, he could not tell which light ball was just tracked by him. Target now.
After not observing for two minutes, Joan was dizzy by these high-speed light with irregular movements, and had to close his eyes and relax.
When the feeling of dizziness and nausea subsided, Qiao An turned to face the ball of light flying in the air and observed with his compound eyes. It felt immediately different, as if opening the door to a new world.
The high-speed light sphere that the human eye can't track is changed to the perspective of the compound eye. It feels that the speed of the light sphere becomes very slow.
Joan turned his huge compound eyes, thousands of small hexagonal eyes, reflecting the magnificent luster of different colors, just like a rotating kaleidoscope, the movement trajectories of the four light are all in view, and you can see clearly .
Joan nodded with satisfaction, raised his hands and snapped his fingers, the speed of the remote control light ball was halved, and then a set of comparative tests was conducted.
In this way, five sets of comparative tests were repeated until the speed of the light ball dropped to the human eye.
Joan sorted out the experimental data, and after a little comparison, he found that the human eye can only see up to 20 to 30 frames per second, but the compound eye can easily capture high-speed images of more than 300 frames per second. Dynamic vision is equivalent to human Ten times 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 that fly at the same high speed.
After testing the compound eyes, Joan next intends to confirm a crucial detail, that is, whether he has a bee needle after becoming a giant bee.
Bee needles are actually specializations of the fallopian tubes.
The drone has no thorns, and certainly does not sting.
Different bees have different bee needle structures.
For example, a bee has a barb on the tail pin, which is connected to organs including the poison glands.
After the bee stings, the barb will sink into the body, and the bee needle will inject bee venom into the other body under the action of osmotic pressure, causing strong pain.
If the stabbed person struggles violently and shakes off the bee, the barbed tail pin will be stuck in its body, free from the bee's abdomen, and pull off the internal organs.
When stinging others, you will also die, and the bee has paid a terrible price for this blow.
