"It should be." The professor's eyes looked at Wang Yilin a little strangely.

"Heh, the experiment you did for me is different from the previous one, right?"

"What's the difference?"

Wang Yilin pointed to his right eye: "Here." ”

Wang Yilin is very satisfied with the professor's eyes now, that kind of frightened and shocked expression.

"Are you sure?"

"Heh, of course."

"Are you sure you're going to have an operation?"

Wang Yilin lay on the operating table again, the gentle surgical lamp shone on his face, and the refractive material in his eyes shone on the cells of the retina, and the light became information, which was reflected in his mind in the form of electricity, forming the impression of light, that is, vision. What is Vision? How is vision formed? Does changing the eyes change the vision? Humans have had another vision since the beginning, so will the world be the same now?

Wang Yilin doesn't care about these, these are what people like professors will care about, Wang Yilin is very selfish, he doesn't care what the world is like, he just wants to change himself.

"Well, do it again, right eye."

Wang Yilin opened his eyes again, the surgical lamp above his head shot a warm beam, there was a colorful halo next to the beam, this time there was no nurse to help him, Wang Yilin slowly sat up by himself, Wang Yilin looked around blankly, and did not feel any change, he began to wonder if his right eye had undergone surgery. The professor sat in the corner, with his legs crossed, an ice pack on his forehead, looking exhausted, and two nurses sat around him, one holding a cup of hot water, and the other putting her hands on the professor's lap, they looked at the professor with eyes full of concern, and tried their best to express their concern.

"You're awake." The professor said loudly, and the two nurses next to him glanced at Wang Yilin, without meaning to get up.

"Well," Wang Yilin slowly moved his eyes, "Professor, what's wrong with you?" ”

"It's okay, I'm a little tired, hehe, okay, go take Mr. Wang Yilin for a physical examination." The professor patted the nurse next to him on the shoulder.

The nurse got up and sat down with a "please" gesture at Wang Yilin, Wang Yilin, entered this physical examination room for the third time today.

"Although it is not obvious, it is true that the sensitivity to yellow has increased, the wavelength range of visible light has increased a little bit compared to the previous two times, although the effect of the experiment is not obvious, but there is no doubt that we succeeded, Mr. Wang Yilin." The professor looked a little excited and stretched out a hand to Wang Yilin.

Wang Yilin smiled slightly and held the professor's hand, "Congratulations, professor, your eye surgery can be said to be amazing." Unfortunately, I didn't feel any change in what I saw. ”

"This is probably due to the fact that there are too few yellow light cells implanted, but this is a good thing, Brother Wang Yilin, I have collected satisfactory data, and it has not disrupted your life, how good is this."

"That's what you said."

Wang Yilin and the professor chatted for a long time, chatting until late at night, and the professor personally sent Wang Yilin back.

Wang Yilin closed the curtains, the whole room was pitch black, there was no light, Wang Yilin groped and climbed onto the bed, lay on his side, and soon fell asleep.

In the morning, Wang Yilin opened his eyes, the familiar ceiling was dotted with dreamy colors, Wang Yilin's heartbeat accelerated, he rolled over and got out of bed and opened the curtains, and the beams of sunlight illuminated the room. Wang Yilin stood in front of the window, the sunlight stretched his shadow and stretched very long, almost covering the floor of the room, in Wang Yilin's eyes, everything in the room was plated with magical colors, and the ordinary small room exuded a magical brilliance. In the room, Wang Yilin's heavy breathing sound was particularly abrupt, he gently brushed the wall with his fingers, the TV, the small table for eating and the tea bowls on the small table, obviously they were all familiar to him, but the flowing colors on it were so shocking.

This is not just a change of color, in Wang Yilin's eyes, even the pure white walls have a complex color that is not inferior to Bonnard's paintings, the vision of the "four primary colors" is simply a dreamy stream, the complex colors make people feel quiet, the seemingly familiar color can not be sure to call its name, and the still things give people the feeling of flowing.

Wang Yilin sat on the edge of the bed, staring blankly at the sunlight coming in from the window, as if there were elves coming from the beams of sunlight, Wang Yilin thought in his heart: "My world has finally changed." ”

The holiday is over, Wang Yilin still got up very early, ate some sliced bread, drank a cup of hot barley tea, and went to work early as usual, Wang Yilin was full of expectations for the first time.

In the eyes of passers-by, this road is still boring and boring, in the eyes of Wang Yilin, this road is colorful, egg scones have the color of egg scones, old buildings have the color of old buildings, no matter how simple the scenery has become different, this is the world of the four primary colors. At the beginning, Wang Yilin adapted very badly, often dizzy and headaches, after all, Wang Yilin's optic nerve, optic nerve center and eyes of the four primary colors do not match. The world under the eyes of the four primary colors is very beautiful, but at the same time it means more information, which means the burden on the brain, if this state continues, Wang Yilin estimates that he will have to go to medical school again, fortunately, in the end, the brain compromised with the eyes and accepted the world of the four primary colors.

Wang Yilin doesn't understand what the principle is, maybe he should go to the professor one day and ask? But this is a matter of "which day", Wang Yilin now feels very good.

Wang Yilin's gaze along the road forward, so that the scenery of the whole road with wonderful colors come into view, countless information in the mind to form a strange picture, old buildings, sitting on the ground, pedestrians walking leisurely after the wonderful color to give people a magical feeling, hurried pedestrians into beating notes, asphalt road and the cars on it become colorful flow of talent, Wang Yilin seems to see a new era, a new world in general.

Wang Yilin wanted to go to work for the first time. This road is too short, and before you know it, you will arrive at the door of the company, Wang Yilin stood at the door of the company, reluctantly glanced at the road, pushed open the door of the company and walked in.

What kind of work is the best job, color work is the best job, but I don't know when Wang Yilin's work has become black and white.

It doesn't matter, from today onwards, my life is colorful. Wang Yilin thought secretly.

The colorful day passed quickly, Wang Yilin did not go home directly after work, but went around to the city center, where there is a small river, for this small place, this is already a big river.

This is what Wang Yilin can think of, the best place in this small city, looking at the city scenery posted by those people on the Internet, there is this river in nine times out of ten, and the neon of the city is reflected on both sides of the river.
