Su Ji couldn't sleep at all.

He looked at his glowing eyes in the mirror in a stupid daze.

He could now understand why the young lady he had just met in the safety staircase was screaming.

Su Ji clasped his hands on his chest, wondering if these eyes had only undergone a metamorphosis today, or had already undergone a metamorphosis, but he had never noticed it. After all, he doesn't look in the mirror in the dark, and these eyes only change shape and glow faintly when there is no light around.

Suji turned his head to the bedroom.

He could only faintly discern the outlines of the bed and wardrobe by the moonlight and street lamps that poured into the room. Now the silhouettes were getting clearer, and he could even see the wooden stripes on the wardrobe. The black and white picture gradually changes to color, but this color is slightly different from the color seen in broad daylight.

That is, does he have night vision now?

Su Ji thought about it, walked to the window and closed all the blackout curtains, and the bed and wardrobe in his vision were not blurred due to the reduction of light sources.

When he walked over to the mirror and looked again, his eyes brightened.

Su Ji turned on the light, and the sudden strong light stimulated him to subconsciously squint his eyes, and when his eyes were a little better, he looked in the mirror again, and his eyes returned to normal and became ordinary people's eyes.

Judging from this, his eyes will change according to the environment, changing to the state that best adapts to the environment.

Su Ji returned to the study.

Dragons are also mythical creatures, and details about dragon's eyes cannot be found.

At most, I will find the information of the details of the cat's eye, and I will look at it.

Cat's eyes don't emit light, and it's inaccurate to say that cat's eyes emit light, because it's essentially a phenomenon caused by the cat's eye reflecting light sources.

When the light shines on the cat's eyes at night, it will feel that the cat's eyes are glowing. This is because cats need to actively dilate their pupils in order to see their surroundings clearly at night. Due to the extreme dilatation of the pupil, more light passes through the cat's retina to the iris behind the eyeball, where it is collected and reflected back.

A cat's night vision is also related to their special eye structure.

In front of their retina there is a structure called a bright blanket that functions like a mirror. When the weak light at night shines into the cat's retina, hits the bright blanket, and then reflects back to the retina, the photoreceptor cells can be stimulated by light, thereby enhancing the effect of light and increasing night vision.

Seeing this, an idea popped up in Su Ji's mind.

In a completely dark environment, the cat's eye can still see things, and he can still see things.

Just do it, experiment decisively, and now the question is where to find a completely dark environment.

Su Ji had an idea.

He went back to the bedroom and looked, the curtains were drawn, and the curtains were very light-shading, but the Roman rod had no curtains, no curtain boxes, and it was inevitable that the light would leak, and it was not enough, and then he walked to the wardrobe, opened the wardrobe door, pushed the wardrobe aside and then hid in the closet, and then closed the wardrobe door.

That's the limit of what he can do without light.

Su Ji curled up in the closet, there was no light in the closet, he couldn't see anything.

Gradually.

If there is no light, then create light.

Su Ji could almost see his eyes glowing, and everything in his vision could be seen clearly, including a thread on the sleeve of the shirt that he had pushed aside.

The situation in front of him reminded him of a passage that he didn't know where he had read - the figure of the dragon appeared from behind the mountain, the huge dragon head was raised, and in the dark night the dragon opened its eyes, and two beams of light swept over......

The wardrobe space was too small, Su Ji sat for a while and hurriedly went out, gasping for breath, and then standing in front of the mirror, the light from his eyes dimmed significantly.

Su Ji didn't turn on the light, and now whether he can turn on the light or not has no effect on him, so he walked to the study, but the light in the study kept on, sat down in front of the computer, and searched again.

There is a flesh-like protrusion above the head of the anglerfish, which resembles a small lantern.

The reason why the small lantern emits light is that the lantern has glandular cells that secrete photogen, which is catalyzed by photonalase and reacts with oxygen to slowly oxidize and emit light. Many fish in the deep sea are phototaxis, so small lanterns have become a weapon for anglerfish to lure food.

In the dark, deep sea, many fish have the ability to emit light on their own, so that they can see other objects during the long nights, facilitate hunting, and find mates and mates.

Although her mother said that they were dragons, they were not the dragons in mythological works, but Su Ji still couldn't help but pull them together.

The ancients believed that there was a pattern to the hiding and appearance of dragons. In late autumn and winter, it lurks in the water, and only emerges when spring comes, and it flies into the sky after the spring equinox. Therefore, "Shuo Wen Jie Zi" has the saying that the dragon "ascends to the sky at the spring equinox, and dives into the abyss at the autumn equinox".

Dragons can dive into the depths of the sea, and if they want to move freely in the lightless deep sea, they can't do without a pair of glowing eyes. Then it is easy to understand that the dragon's eyes will glow from this.

Thinking of this, Su Ji wanted to try again, in addition to having night vision, its eyes also had the function of bringing diving goggles.

Su Ji excitedly ran to the service balcony and brought a big red bucket from the laundry cabinet.

He was about to fill the red bucket with water and stick his head in it to try it, but he had just taken the big red bucket down and put it back again. Because he thinks he's a little stupid if he does that. Buried your head in a big red bucket full of water, how funny you think.

We'll talk about it tomorrow.

The gym where he got the card has a constant temperature swimming pool, and the constant temperature swimming pool is the confidence of the gym to sell such an expensive fitness card, so it is better to go to the constant temperature swimming pool tomorrow to try it.

Su Ji returned to the study and searched around the Internet, and suddenly felt that his eyes were sore and swollen, as if he had overused his eyes.

The soreness in his eyes became stronger and stronger, and he felt that he couldn't open his eyes, so he could only squint, and Su Ji took one last look at the lower right corner of the computer screen.

It was close to three o'clock in the morning.

Be sure to sleep.

And then what to do if you are a little hungry again.

You can rest with your eyes closed, you can't be hungry, and your stomach will be rumbling all the time.

Su Ji boiled a pot of water and soaked a bowl of instant noodles, because he no longer felt better in front of the computer screen, but just like that, he squinted his eyes and ate noodles and drank soup, and then ran to sleep.

Su Ji was very excited, and spent the night thinking about what functions his eyes would have besides night vision.

The function of the diving goggle must be there.

Will there be a perspective function.

What about the function of emitting X-rays?

It would be handsome to have a laser eye like Superman.

The fiery eyes are not very good, because the setting of the fiery eyes is - just the wind stirs up the smoke, which makes a pair of eyes red, making it an old eye disease, so it is called fiery eyes. But even so, the fiery eyes have the function of seeing through the changes of the gods and monsters and identifying the authenticity.

Anyway, God knows when he fell asleep.
