The visual perception of most animals on Earth is mainly composed of an imaging system similar to the cornea and lens, and a photoreceptor system similar to the retina. The refractive system of the human eye is already more advanced than the most advanced lenses available today, but it is still imperfect and there are still aberrations.

The aberration of the human eye is related to the structural imperfection of the human eye, such as local deviation or irregularity, which makes the light passing through the deviation deviate from the ideal light path, making it difficult to image perfectly on the retina.

There are more than 30 kinds of chromatic aberrations of the human eye, such as corneal aberration, lens aberration, retinal aberration, etc., which make the optical system of the human eye unable to fully play its role perfectly, reduce the imaging quality of the retina, and limit the sensitivity of perfect vision.

There are two types of aberrations: low-order aberration and high-order aberration. Low-order aberrations mainly refer to refractive errors such as myopia, farsightedness, and astigmatism, while higher-order aberrations are mainly comic aberrations, spherical aberrations, and halos. If there is no low-cost aberration, that is, there is no myopia, farsightedness, astigmatism, etc., and the visual acuity can reach 2.0 calculated by the decimal method, and none of the ten modern people have such vision. And if the higher-order aberration disappears, the visual acuity can reach 4.0, that is, the line of symbols that can stand twice as far as the average person on the eye chart and see the 2.0 symbol, which is the kind of person that is unique in ten thousand, and it is also the limit that the human eye can reach.

Why the limit is only 4.0, the limit of vision of the human eye is not only related to the imaging system, but also determined by the size of the individual optic vertebral cells on the retina. The size of the optic vertebral cells is the highest resolution of the human eye. The diameter of a single optic vertebral cell is about 1.5 microns, and the visual limit of the human eye is 4.0.

This time, due to the deliberate waste of the star core, there is a lot more active electricity than before, and the energy contained in the green mist is very abundant. And Wang Fen's eyes were not only very delicate, he also desperately opened his eyes wide. These highly active energies hit his bare eyes wave after wave.

The human eye continues to deteriorate with age, and the process is almost irreversible, and the energy-filled green mist of the star core constantly changes Wang Fen's cornea, lens and retina, so that his vision, which was no longer 2.0 due to perennial games, continues to improve, and continues to restore, reaching the limit of the human eye's 4.0 vision.

And the price is that the eyes are spicy tears.

Although the green mist had a great impact on his body, it was only the energy emitted by the star core after all, if nothing else, the change in Wang Fen's eyesight would end there.

The vision of 4.0 is far beyond the limits of ordinary people, but it is not enough, it is not enough to see through the thick fog to see the branches in your hands.

Wang Fen shed tears and persevered.

What about the sting.

If you want to make this fog, you can no longer blind his eyes.

There is no fear of fire.

Let this eye see through all the vanity of the world.

He gritted his teeth, trying to see through the fog in front of him, but it was always a green patch, when he transformed the battery before, the star core transformed his body by the way, it was just his unconscious behavior, even if the current energy mist gave him a mask to do SPA, he didn't realize it, or it wasn't his subjective wish. Therefore, these energies have a limited effect on his body, only speeding up the rate of metabolism and making the new cells healthier, more energetic, and more delicate, but essentially not qualitatively different from the original cells.

Only these eyes, in the fog, he desperately wanted to see through everything in front of him, desperate to see subtle changes.

When the energetic green mist came into contact with Wang Fen's eyes, due to his urgent desire, unpredictable changes occurred, the green mist slowly seeped in, and Wang Fen's corneal lens continued to change and recrystallize, adjusting his refractive system, reaching the limit of the human visual structure.

But that's not the end of it.

The green mist continued to accumulate on the surface of Wang Fen's cornea and lens, gathering more and more, thick and substantial. Wang Fen's eyes are getting greener and darker. Finally, Wang Fen roared, and the green mist gathered in his eyes continued to pour into his eye sockets, as if they were constantly absorbed by his eyeballs.

The star core originally thought that Wang Fen would be able to achieve 4.0 vision at most this time, but with Wang Fen's roar, its transformation process of the tree branches suddenly stopped, and he only felt that the connection between Wang Fen and Wang Fen was suddenly strengthened.

Previously, the star core used Wang Fen's body to feel the outside world, but it did not completely use Wang Fen's own organs, for example, the star core used not Wang Fen's simple naked eye, but Wang Fen's entire body to feel the changes in light, so as to achieve an incredible resolution.

At this time, the star core felt a burst of calls from Wang Fen's eyes, and the synchronization between it and Wang Fen reached an unprecedented height, so it involuntarily moved its perception to Wang Fen's eyes, and the energy also surged.

The formless and insubstantial green mist continued to solidify on Wang Fen's eyeballs, and in the end, most of the green mist was sucked away by Wang Fen's eyeballs, and his eyes became brighter and brighter, emitting a light green glow. As his eyes glowed, Wang Fen only felt that he didn't know if the fog had faded, or if his eyesight had improved, and he could dimly see the outline of the branch in his hand.

What was left in his eyes was an extremely thin film on the surface of the cornea and lens.

This film can be said to not exist materially, nor is it formed by the electrical energy in the green mist, but is composed of the indescribable energy of the past that the star core feels Wang Fen's eager call and transmits to him, although it is only a little insignificant, but it makes the star core hurt for a long time, this is all high energy, and it is its lifeline.

Stimulated by this energy, Wang Fen's retinal cells also rapidly divided and multiplied, becoming only one-tenth of the original size, and the number increased by more than ten times, and they also became extremely active.

At this moment, his eyesight suddenly broke through the limit of human beings, reaching more than 12.0, and the spectral range he could see was much wider. It's a pity that his desperate desire is only to see the branches in his hands, not to be able to become a clairvoyant eye, otherwise it may really come true.

At the same time, nourished by a lot of energy, his tear ducts have become extremely developed, if he is going to be an actor now, he can cry whenever he wants, and he can cry like rain at any time, without eye drops and wind oil essence, it is like an emperor-level tear control.

Wang Fen didn't know about these for the time being, and his attention was completely focused on the branches in his hands.

The branches in the line of sight became clearer and clearer, and then a little green glow lit up from the middle of the branches.

Hazy, flickering and flickering, like fireflies in the dark.

Wang Fen was very excited, the first time he saw the star core transformation object, such a ghostly light appeared, could this be the new function of the star core.

The glow grew larger and brighter, and Wang Fen finally saw that the light was coming through the cracks in the texture on the surface of the branches.

The pale green glow, dark, mysterious, but very stable, is no longer a ghost fire that will be extinguished at any time.

As time passed, the star core was still the same star core that was half scorched black and half fluorescent green, constantly changing postures with Wang Fen's kneading, and the branches were no longer branches.

"Separation ... Begin. The star core continued to explain, being sucked away by Wang Fen a little of its precious high energy, and the heartache and the unspeakable star core were no longer wasted, and they just wanted to quickly complete the transformation of the car's ears.

The ghostly light burned slowly but surely from the inside out to the branches in Wang Fen's hands. At the same time, a large amount of yellow mist poured out from the cracks on the outside of the withered and yellowed branches.

The yellow mist was not pure energy like the green mist, but extremely tiny particles, if it weren't for Wang Fen's current eyesight, he wouldn't be able to see what was going on with these yellow mist at all. These particles are the other impurities of the flying cellulose nanofibers in the branches, which are broken down into extremely tiny nanoparticles by the star nucleus, which are broken down and scattered in the air.

The glow burns, and the dead branches seem to be reborn.

The green mist is thin, and the yellow mist is pervasive.

Yellow and green, one withered and one prosperous, such as the change of seasons, such as the transformation of life and death.

With the last bit of green fire, burning away the unwanted components of the star core in the branches, turning into a faint yellow mist and dissipating into the air, what remained in Wang Fen's hand was a small green ball of light, which was wrapped in a pile of crystal clear translucent floating objects.

The star core then explained that the ball of light was its power grid of electrical energy. Just as the particles are suspended in the pulp before the final pulp in the papermaking process, these cellulose are broken down into perfectly structured individual nanofibers, which are suspended in a computer-constructed grid light sphere at the star core.

And it's packed with perfectly structured fibers.

Due to the production process, the nanofibers currently produced by human beings are doped with too many impurities, and the crystal structure is not perfect, and there are various waste products, so they can only reach five times the strength of steel. If they are all perfect crystals, and then combined with a perfect process, they can easily achieve double the strength.

Although the current processing capacity of the star core is not able to make such nanofibers, there is no difficulty in screening the perfect fibers.

Wang Fen tried to pinch the ball of light, although the ball of light is composed of a power grid, it feels like a real thing, the touch is unexpectedly very soft, and it is as smooth as milk. Not only was it not broken by him when it was pinched into various shapes, but he could also clearly feel the smoothness of these fibers wrapped in the ball of light. Wang Fen couldn't imagine that nanofibers, which are very strong and strong at the nanoscale, could be so soft after being broken down into individual nanofibers.

And such soft fine particles, when combined in a specific way, will become a material harder than steel, which makes him feel that macro and micro are really very magical and contradictory.

For a long time, Wang Fen stared closely at the ball of light the size of a duck's egg, and then easily opened his hand, the ball of light seemed to have no weight, and slowly flew away from his palm, floating like water droplets in space.

Look at the pale green ball of light floating in the air, the transparent and slightly milky suspended matter in it.

No matter how Wang Fen looks at it, he feels that it is too much like his essence, and it is an essence that can fly and shine.
