Free Web NovelChapter 572: Chapter 382: Optical Invisibility
The eagle slowly spread its wings and flapped them,
seemingly getting familiar with its own body.
Its wings had undergone optical invisibility modification, and now under the sunlight, they were becoming somewhat hard to see, much like a mosquito that disappears in flight.
Originally, the visible light reflectivity of this eagle’s feathers was around eighty-five percent, making it easy for creatures on the ground to spot it when soaring on a clear day, especially such a giant creature as the eagle, which could easily be seen by humans in the city.
But now the eagle’s feather reflectivity has been reduced to zero point three percent, achieving an improvement of over two hundred times, and they also have light-scattering traits, allowing the light penetrating the feathers to bypass the body along a predetermined path, similar to the principle of optical fiber diffraction, and ultimately restoring its original propagation direction when emitted from the other side, achieving complete invisibility.
This means if the eagle were to soar in the sky with this special optical invisibility feather, most people would only hear a deafening hum, but upon looking up, they would only see the vast blue sky and white clouds, at most spotting a turbulent white vapor.
This sounds mysterious.
But there are many examples in life.
For instance, some moths have invisible scales on their wings, so although their wings aren’t completely transparent, many people still can’t spot them when they fly under the sun, and some butterflies, many people as children would chase butterflies in a flower garden and find themselves stunned when a butterfly seemingly vanished—in reality, it wasn’t that the butterfly disappeared, but its wings made it "optically invisible."
Another example is current fighter jets, which achieve optical invisibility at high enough speeds not by relying on stealth coatings, but by the misty airflow enveloping the fuselage during high-speed flight, achieving short-term optical invisibility.
Wang Ye estimates that at least seventh or eighth generation fighter jets will be needed to achieve true optical invisibility, because until now, humans have not fully mastered this technology. The reason Wang Ye could transform the eagle’s feathers into optical invisibility feathers is because of his very high accomplishments in physics. After extensive research recently, along with the system granting him knowledge far surpassing human peaks, any technology he casually picks from his mind should be able to directly advance a discipline forward by several decades or even centuries.
Achieving optical invisibility for himself wouldn’t be a difficult task,
but it’s unnecessary.
Because for optical invisibility,
he would have to cover his body with a layer of crystals or coating,
which would lead to a significant change in his appearance, affecting his social interactions, not to mention his combat power, as such coatings would consume extra energy.
Moreover, even if a layer of invisibility coating were grown, it still couldn’t achieve complete invisibility, as the lowest he could achieve now is zero point three percent visible light reflectivity, similar to glass. Hence, when standing still, a faint human shape could still be observed by the naked eye, only achieving complete invisibility at high speed or when soaring in the sky to ordinary people’s eyes.
This kind of condition-specific invisibility holds no meaning for Wang Ye. If he were to make this low-reflectivity coating, he might as well simulate a chameleon and change his skin color to match the surrounding environment, which could conceal him more efficiently.
Wang Ye dismissed these thoughts from his mind and squinted, observing the eagle before him. Its countless physical traits transformed into streams of data rushing into Wang Ye’s mind, giving him nearly nanoscopic mastery over the eagle’s traits, "The current overall capability of this eagle should be about one-third of mine. Its best speed should be about two-thirds of mine, and it’s already enough to break the sound barrier."
A bold idea suddenly arose in his mind,
since the eagle now has the optical invisibility ability and two-thirds of his speed.
Could he use the eagle for transportation?
It’s known that the eagle’s body is extremely large, and the area exposed to sunlight is broader than Wang Ye’s, meaning its energy absorption efficiency is also higher. Coupled with its thick feathers that allow sustained gliding in the air, it only needs to spread its wings to maintain long glides, occasionally flapping to aid it; this mode of flight is much less strenuous than Wang Ye’s constant output.
While in terms of speed limit, the eagle may not match Wang Ye,
for long-distance soaring, the eagle should be much stronger than Wang Ye.
With this thought in mind, Wang Ye directly mounted the eagle.
Under his Mind Control,
the eagle promptly began flapping its wings.
Rumble!
The entire mountain suddenly quaked, countless trees and vegetation around were snapped at the waist and flew in all directions, while the eagle’s heavy body quickly ascended.
Mainly composed of chromium and diamond, its skeleton now allows it to exert far greater power than before, so despite increased muscle density and bone density and nearly doubled body mass, its speed is still much faster than before.
However, due to its massive size, the eagle still has the flaw of too slow acceleration. Although its maximum speed can exceed the speed of sound, it takes nearly a minute to accelerate from 0 to the speed of sound.
