"I'm sorry to tell you that you have lung cancer, and if you are actively treated, you still have a chance of recovery, does your family know? We recommend that you be hospitalized and actively cooperate with the treatment! ”

"How much longer?"

"You're in the early days, or do you have ......!"

When Lu Zhiyu walked out of the hospital, he was in a trance, feeling that everything was not real, as if he had a dream, and the people rushing by him were not in the same world, as if he was not in the same world as himself, a line that could not be seen clearly, and he was separated from this world.

Lu Zhiyu has no intention of treatment, cancer, there is no need to waste money, even if it is death, Lu Zhiyu does not want to insert a tube, and dies in pain on the hospital bed.

Since the lungs of the fish on the land are not very good, they often cough, they have been working in the capital for a few years, and they cough even more when they encounter the haze weather, although they have long had the idea of leaving the capital, but because the work is at its peak, it has been delayed again and again, and it has become more and more serious some time ago, and the fish of the land is just an old problem, and I didn't think too much, but I didn't expect it to be such a result.

quit his job, bought a plane ticket, and dragged a suitcase on the journey home, Lu Zhiyu was born in Jiangcheng, his hometown is a single-door house, which has been renovated and looks quite modern, but because no one lives, the courtyard looks dilapidated and unpopular.

Lu Zhiyu's parents have long passed away, and there are no close relatives at home, good classmates, but also gradually lost contact in the society, when they meet again, but there is no taste of the past, utilitarianism and life are simply written on the face, it is better to miss each other, although colleagues talk and laugh, but it is difficult to communicate like a teenager.

Think about it, I really feel that this life is quite boring, as if a set of life templates used by millions of people have been put on me, except for cancer, I am like a marionette, led by people, by the whole society, and by the inertia of fate.

The house has not been inhabited for a long time, and there is dust everywhere, so I lifted the cover and began to clean and tidy up, turning out a lot of old things from the corners and corners, childhood toys, textbooks, and graffiti, full of nostalgia.

"Eh, what is this?"

By chance, Lu Zhiyu found an old mahogany box placed on the cabinet in the utility room, and after opening it, he found that there were some messy things inside, including a badge with a peasant's head, an inkstone, a red book, and of course, the most eye-catching thing for Lu Zhiyu was a white painting scroll.

Because this scroll is too white, as if there is no trace of pollution, the texture looks like a delicate feeling of being smeared with a layer of oil, you must know that the paper has been put for a long time, there will naturally be discoloration, this thing must have some thoughts, it is really strange to be littered in the box like this, and it can be preserved so well.

These things should have been left by grandpa, Lu Zhiyu was very curious, I didn't know what this painting was, and it was slowly unfolded on the living room table, and Lu Zhiyu, who was looking forward to it, instantly became disappointed.

"What, it's an empty painting!"

When Lu Zhiyu was about to put it away, he found that there was a black dot on the painting, and when he looked closely, he found that it was a small grasshopper, and Lu Zhiyu smiled dumbly: "With such a big banner, just draw a small invisible grasshopper, this is really a waste!" ”

Lu Zhiyu looked at it carefully, and suddenly went up with his hand, and immediately found an amazing scene, Lu Zhiyu felt as if his hand had passed through a gap and directly touched something.

Lu Zhiyu was startled, withdrew his hand, and saw that a grasshopper was dragged in his hand, and Lu Zhiyu was frightened: "I'll go, what is this!" ”

The moment he let go, he saw the grasshopper immediately jump up and stumble on the floor in the living room, Lu Zhiyu looked at the grasshopper in disbelief, immediately got up, looked at the painting, and found that the grasshopper on it had disappeared at the moment.

"Taken out? Alive? ”

Lu Zhiyu looked at the painting, and then at the grasshopper bouncing on the ground, and his mouth grew, and he found that he seemed to have found something unbelievable.

Lu Zhiyu is also a lover of online literature, and he reads novels for an hour every day before going to bed on weekdays, and he is no stranger to this kind of thing.

"Is it a carry-on? Portable space? The treasure of the farming stream? ”

Although people are dying, but Lu Zhiyu does not have the kind of complaining about the world, self-defeating thoughts, life has to live, especially the remaining days are not much, and must be lived to the fullest, at this time to find such an interesting thing, for Lu Zhiyu, it is simply an unexpected joy.

In the next few days, Lu Zhiyu conducted many experiments on this painting, and there was indeed a space in the painting, but it was different from the space in his imagination, and Lu Zhiyu called it a painting space.

Its space is flat, from a scientific point of view, this space is not three-dimensional, but two-dimensional, all things that enter it, will be automatically sealed into a two-dimensional existence, suffered from the dimensionality reduction blow, but after becoming the existence of the two-dimensional world, it will return to a three-dimensional form, Lu Zhiyu can't figure out how this magical situation happened.

This is the first discovery, Lu Zhiyu by putting all kinds of things into the painting space, the conclusion reached, the second discovery is that in the two-dimensional world of the painting space, there is no time, and entering it is like entering an eternally still river, no matter what is sealed in it, no matter how long it is placed, it will still be the same.

The third discovery is that the painting space seems to have a very repulsive situation for living creatures, Lu Zhiyu wants to try to put living things into it, but finds that the current painting space is not able to withstand too powerful living creatures, the moment the chicken and duck are put into it, it is torn apart, disappearing, Lu Zhiyu guesses, it may be that the entrance of the painting space can not bear it, so it fell into the dimensional gap.

Therefore, Lu Zhiyu caught a few ants and put them in the painting space, and found that there was no such situation, and the portraits of several ants climbed quietly on the painting scroll, not moving, as if they were frozen by time.

Lu Zhiyu is very curious, why there is no time in the two-dimensional world, if there is time, then it is equivalent to a real world, in this way, the meaning of painting space is greater, I don't want to now, purely as a storage space.

Einstein's general theory of relativity explains the concept of time as a single dimension, and from this situation, the world in which human beings live should belong to the fourth dimension, but human beings cannot directly observe the fourth dimensional time, so human beings are only three-dimensional creatures.

The same is true of the two-dimensional world, even if time cannot be observed, but time should exist, and it should not disappear like this, Lu Zhiyu decided to look at and confirm this situation from a different angle.
