After a six-hour drive to Beijing, a taxi ride to Sihui Station, and a two-hour bus ride, the three of them finally returned home.

The time was 8 o'clock in the evening, the sky was still slightly bright in summer, and the three of them walked home with large bags of luggage, Yan Xi was silent all the way, secretly looking at this land, there was a feeling of both familiarity and strangeness. The former red brick and blue tile bungalows have been replaced by beautiful two-story small western-style buildings, and the fish pond in the middle of the village is barren, and the surrounding area is unevenly filled with a lot of soil, like the teeth of a soil dog, which looks disgusting.

Along the main road, turn right in the penultimate alley, and the last house is Yanxi's house.

Yan Xi is the first time to come here, from the outside, his home seems to be good, the wall is pasted with white tiles, the right side of the door is a flower garden, the left side is planted with some leeks, and the trough used to feed the cattle is placed vertically at the door. There was water in the trough, and the small-leaved lotus flowers were lazily blooming in it, and Yan Xi came closer to see that there were still a few small fish swimming in the turquoise and turbid water.

Xi Niang opened the door, Yan Xi followed into the door, and put the luggage at the door. The lamp was turned on by Xi Ting, and the first thing that caught Yan Xi's eye was a wooden screen, divided into four pages, which were engraved with four scenes: Meilan, bamboo and chrysanthemum. On his left hand side is an old red battery car charging.

There was a dog barking in the yard, the sliding door inside was opened, and a middle-aged man with a cane smiled and said, "I'm back, the meal is ready, hurry up and eat it while it's hot." ”

Xi Ting threw the backpack on her body to the middle-aged man, and jumped into the inner house, she was also hungry.

Yan Xi looked at the middle-aged man, and didn't feel anything, he was just a very ordinary man, the elder had a Chinese face, a little wrinkles on it, his skin was a little dark, he was not tall, and he was holding a cane on his arms, which looked a little funny.

Xi Niang helped the middle-aged man into the house, Yan Xi followed behind, and the dog in the yard still barked, but he didn't feel irritated.

Before entering the house, Yan Xi looked back at the outhouse she had just walked through. The line of sight ranges from the nearest aluminium and glass sliding door, to the grey tiled floor of the corridor, to the wooden screen, and finally to the dark blue security door. This short distance brought Yan Xi an extremely strong feeling, as if it was a singularity at the center of the Big Bang, countless waves shot into his mind, he seemed to see an infinite time and infinite space, and then a black dot appeared in front of him, and the huge sucking pulled his mind closer to a strange space.

Yan Xi in this space looked at everything distractedly, the sky was blue, the water was clear, there were weeds on the side of the dirt road, there was a dilapidated old house, the walls were still made of adobe bricks, and the door was made of several wooden planks. The house was inhabited by a young mother and father, a surviving grandparents, cucumbers were planted in the yard, and yellow flowers had bloomed, and an old ox was lying in the shack, its tail wagging to drive away flies from its body.

"Here?"

"Memory black holes." Qianyuan didn't know when he appeared next to Yan Xi, and the two stood in mid-air, quietly watching the pictures flow.

From babies to children, Xi Xi was very naughty when she was a child, and she was often spanked by Xi Niang with a broom, crying and crying. He ran away from home twice, and returned home silently without leaving the village both times, from the beginning of the resentment, to fear and confusion, and then to the loss and gloom, sadness accompanied his childhood.

Later, Xi Xi began to listen to his parents, like a rabbit baby, studying hard every day, not watching his favorite cartoons, the child with a big schoolbag walking alone in the sunset, he doesn't like to talk very much, he likes to stay alone in the room, he doesn't think about anything, he doesn't do anything, he just sits on a chair, staring at something in a daze.

The turning point came in the last year of elementary school, when a new young female teacher named Chai Qun was not tall, wearing glasses, clean short hair, and often wearing simple silver stud earrings on her ears. Cheshire teaches math, is very good at math, and is appointed as a class representative.

The first time he saw Cheshire, he was like a traveler walking in the desert who saw a clear spring, and he couldn't wait to tell her everything about himself, but he didn't dare, he was afraid that it was just an illusion. Gradually, under the mask of calm and calm, there is the flesh and hazy love that teenagers should have.

When Yan Xi saw this scene, she remembered a sentence she heard from somewhere: If you feel lonely, please enjoy and love it deeply, there are thousands of things in the world, but loneliness belongs only to you.

On the day of my graduation from elementary school, it rained heavily, and I stood alone in the rain for a long time, and the lights in the school classroom gradually went out, and it was pitch black, and there was no sign of Cheshire. Perhaps, Mr. Chai didn't come today. Thinking about it, wearing a large black raincoat, walking alone in the heavy rain, his sandals stepping on the water, cold and cold, like his mood at the moment.

From that day on, I was still the same, lonely and silent. But sometimes he would laugh, and when he saw a stack of bricks, one of which was broken, he would laugh; He would laugh when he saw only a pebble in the middle of the road scorched by the sun; He laughs when he sees a different one of the same grass.

He looks stupid when he laughs, like a fool, but he likes to laugh and like to be seen as a fool.

Qianyuan put his hand on Yan Xi's shoulder and smiled: "Those who can find the door, it is easy to have one." Young man, you see that people's kung fu is still far behind. ”

"This slut!" Yan Xi gritted his teeth and said, he suddenly thought of something, turned his head to look at the abyss, "It stands to reason that I should have this experience too, why am I not impressed at all?" ”

Qianyuan continued to look at the screen, "What do you mean you should have?" Do you have one? I can't carry a few pounds and taels by myself, and I look like an uncle every day, I think you have a brain problem. ”

As soon as Qianyuan raised his hand, a black ball appeared in his palm. "This ball is you, it's all black inside and out, and people can see through it at a glance." The ball vanished, and an ordinary stone appeared, and the stone had been cut into a small corner, and it seemed to be jade, but there were too many magazines.

Qianyuan said: "You know the gambling stone, Xi Xi is like a gambling stone, all you can see is the corner that has been cut, and no one knows what is inside." Is there a deep sense of frustration now, even the old man is just a drop in the bucket compared to him, if it weren't for his generalization of thinking, we might not be able to discover this secret in our lifetime. ”

"Memory black holes. Unexpectedly, if you still exist in the material universe, you can come into contact with the world of thinking and directly lock your memory. Yan Xi said, frowning, "Doesn't this mean that he directly buried his thinking, so who is Xi Xi now?" ”

"The Buddha talks about reincarnation, and the Tao talks about reincarnation. It's him and it's not him, and I can't understand who the current Xixi is, maybe it's the same as you and me. Qianyuan said, with a wave of his long sleeves, a curtain of light enveloped the two of them.

The picture in front of the two began to become distorted, much like Van Gogh's oil paintings in his later years, giving people a very uncomfortable feeling.

When a huge face appeared in front of the two of them, everything in this space seemed to have come to a standstill, Yan Xi and Qianyuan's bodies turned into intertwined threads, and the light curtain in front of them was just a dozen points of light that kept moving, and after stagnation, the points of light were suspended in mid-air, and the light curtain disappeared.

The huge face looked at the two of them indifferently with deep eyes, and two colorful stones shot out of his eyes, which fell into the eyebrows of the two of them.

Yan Xi and Qianyuan recovered their original bodies and gasped for breath. What the fuck are we provoking!

"I can sense everything, wait until I am innocent, and go quickly." Giant Face said.

A curtain of light appeared in front of the two of them, and Qianyuan bent down towards the giant face and bowed his hand to say goodbye, stepping into the curtain of light. Yan Xi still had a doubt in her heart, and asked loudly: "Is it you who is also the current Xixi?" ”

The giant face began to distort, like a stirred watercolor, through the initial slowness, the speed of distortion became faster and faster, and a bottomless whirlpool appeared in the middle, and out of the whirlpool came a young boy, wearing the uniform blue striped school uniform of Chinese students, and white yellowed flat cloth shoes.

The young man's face was calm, he walked very slowly, but his speed was fast, and he reached Yan Xi in a few steps.

The young man stretched out his immature right hand towards Yanxi and smiled slightly.

"Yanxi, hello, my name is Lingxi, it's nice to meet you."

Yan Xi carefully shook hands with Ling Xi, and a monstrous wave broke out in her heart. It was this ordinary boy in front of him who changed all the embarrassing fates in the universe.

Ling Xi let go of his hand and said calmly: "I can answer you three questions, in exchange, at some time in the future, you need to enter this space, and you can never go out." ”

Yan Xi lowered his head and pondered, he recalled his life, like a horse watching flowers, but it was just a wind and snow. He looked at the dreamlike scene around him, and it looked good to use this place as a cemetery, his eyes slowly became resolute, he nodded, and asked, "Who is Xi Xi now?" ”

Zero Xi scratched his head, thought for a while and said, "It seems to be me." He was created by me and should be a part of me. ”

"Who are you?"

"I'm zero, this question doesn't count, I answered it just now."

"Okay, so can you describe the process of creating the mess?"

Ling Xi was puzzled for a moment, he didn't understand why Yan Xi asked this, and said: "At that time, it seemed that I was bored alone, so I imagined another self to play with, fill in some characters, experience something, it was easy, and then I found that he seemed to be more able to adapt to the real world, so I let him dominate the body." ”

When Yan Xi heard such a simple answer, he sighed in his heart, could he be like Xi Xi, a character who existed for fun and fabricated at will, if so, who was he?

A deep sense of fear lingered in Yan Xi's heart, and he didn't dare to ask this question.

Yan Xi shook her head stiffly at Ling Xi, and a light curtain appeared between the two. Ling Xi said: "You may not think, I will answer you one more question." Do you know why I'm called Lingxi? I didn't come up with the name myself, there are words engraved on the door as zero, the number zero, and I guess it means zero. In the thinking universe you are 1 and I am 0, and I am infinite. ”

Yan Xi couldn't see Ling Xi through the light curtain, presumably Ling Xi should be able to see herself. He was thinking about the meaning of this sentence, and he didn't understand very well, 0 is infinite, 0 is nothing, how can it be infinite?

Yan Xi remembered a Zen saying: Bodhi has no tree, the mirror is not a platform, there is nothing originally, where to stir up dust. It seems that Buddhism has had a great influence on Lingxi.

True or fake? Right or wrong? Who knows.

Yan Xi entered the light curtain and disappeared.

Ling Xi pulled out a thin black line from the light curtain that was about to disappear, and he thought that one day in the future, when Yan Xi came back, it should not be considered a breach of appointment to return this memory to him.
