The universe is infinite in our understanding, and it is difficult to see or imagine whether it has boundaries or not.

It is known that one dimension is a point and a line, a second dimension is a plane, three dimensions is space, and four dimensions is time.

We live on the basis of three-dimensional space, can feel and see space, and move freely in space at the same time, and our understanding of the universe is only infinity and infinity, which is based on the conclusion drawn from the perspective of three-dimensional.

For the fourth dimension of time, we can feel its existence, but we have no way to "see" the form of time, let alone move in time. So in this dimension, we just guess that the universe may not be infinite, maybe what we see is the same as the "two-dimensional creature" ant that can only feel the plane, and the infinite world in the eyes of the ant is just the size of a piece of paper to us.

The four dimensions alone are far beyond the scope of our imagination, and beyond the four dimensions, according to the great scientists deduced that the world has a total of 12 dimensions, we can only look forward to the future.

And at this moment, in the darkness of our three-dimensional cosmic space, it was abruptly dispersed by a light, and even the light of the superstars in the universe was obscured.

Common sense says that the propagation speed of light is the speed of light, but this light exceeds the speed of light and passes through in an instant, with an immeasurable total amount. And in violation of the known laws of physics, the sound is propagated:

[Time retrospective····· Capture the middle of the pre-universe epoch that changes world time. 】

【Searching for space····· A total of 102.3 trillion adaptation sites were found. Seed Hunting····· Lock the seed and successfully generate an education bracelet. 】

[Start the seed education program, and the education bracelet is being distributed, please check it.] 】

Earth time, June 28, 2017.

At GN University in N City, G Province, a slender boy with a sharp head in front of the window facing the school's central water department in the library kept raising his hand and looked at his wrist movements in dismay, and the boy who looked neat and neat was very uncalm at the moment.

For Xie Dan, who stood in front of the library window and looked at his wrist silently, today should be a very ordinary day. But after that thing appeared in the sky, it was destined that Xie Shan would not have a normal day again.

As a student party in the senior year of GN University who is about to face the final defense, it is normal for him to soak in books and write a thesis is what he should do now, but Xie Shan is not in the mood to write a thesis now, and looks at the thing in his hand with blinded and doubtful eyes.

The thing is a smooth dark silver bracelet full of sci-fi feeling, and you can faintly see bits and pieces of starlight.

The bracelet is about the same size as a regular watch, and it looks like it is made of silver metal, but it is fuller than silver, and it is small but gives people a noble feeling.

This can be accepted by Xie Dan, Xie Dan was shocked that he looked at the fan-shaped light screen that began to glow in the air after the bracelet, and Xie Dan, who was an engineering man, knew that this was definitely not something that could be achieved with current technology.

Things go back to 10 minutes ago: Xie Dan, who was reading a book seriously in the library, was almost blinded by the sudden light that filled his eyes without warning, when did the library install high-power lights?

Xie Dan, who was puzzled after seeing the light just now, heard the voice that made him pause, "Studying too much will still cause hallucinations?" What changes the world, is the education plan a new policy of the country, this voice is not scientific, how does it feel like it is the voice in the head!? ”

Xie Dan felt that what he was thinking was very reasonable and normal. But after looking around and finding that all the alumni around the library desk were in a state of panic like himself, he knew that he might not be the only one hallucinating, and his strong intuition made Xie Dan ask the classmates next to him with a little trill

"You heard that strange sound just now!?"

"Yes, you heard that!?" The acne man next to him was shocked and asked in a tremolo,

"I thought I was having auditory hallucinations, but it's okay."

"I also heard," the students around me began to come back to their senses and quickly communicate, "Is there something wrong with the library's radio?" ”

"I usually listen to the school radio, but this time it is definitely not a library or school radio." The girl on the other side who didn't know said with an affirmative face.

"I don't think so, that voice seems to have come straight into my head. And that voice sounded weird, but I understood what it was saying. "More and more people are starting to notice that something is wrong.

Xie Shan looked at the heated discussion of most of the classmates a little messily, and a few classmates began to ask about the situation at home, "What, the capital also heard it, Mom, are you sure you're not kidding me?" Don't be kidding at this time."

Judging from the student's retelling, this time the story covered a lot. Intuition told Xie Dan that something big would happen next.

Seeing that the classmates around him did not stop discussing and began to call and inquire, Xie Dan, who had no brains, simply closed the computer and got up to leave the library.

didn't think that as soon as he walked out of the library gate, Xie Dan suspiciously found that the people outside were still looking at the sky, and their fingers were still pointing at the sky.

"Look at what is in the sky"

"Oh my God, there are so many things that seem to be flying"

"A hole in the sky"

Xie Shan reacted, turned around and took a few steps back, crossed the library and looked at the sky, his pupils were uncomfortably contracted by the abnormal change of sunlight, and he subconsciously opened his mouth wide after seeing the scene in the sky.

There was a spherical hole next to the sun in the sky, as if a huge hole had been pierced in the sky, and the black hole larger than the sun even weakened the sun's rays, as if it was swallowed up by the huge hole, so that the sunny sky that was obviously 10 o'clock in the morning turned into a sunset, and the sun became no longer dazzling.

At the moment, many dense dots are spewing out of the cave, and they are rapidly spreading to the entire air, and the already abnormal sunset sky is becoming darker because of these massive dots.

Some of them fell straight down like rain, and unlike the raindrops, when they were about to land on the ground, the dots began to turn clearly, as if each dot had a life and had its own clear goal, and when it was about to land, it began to emit a soft light to give people a mysterious sense of sacredness, as if they didn't like the dim environment or appeased the people below who began to panic because of the sky vision, and the dark sky became beautiful.

At first, he was still a little frightened when he saw the hole in the sky, which reminded him of the aliens in the movie, after all, the biggest fear comes from the unknown, and the unknown things that appear behind the sky increase his fear.

Under the effect of fear, Xie Dan involuntarily took a step back, and ran into the library after finding that the sky was full of those small dots.

The crowd around them also began to look for the building after seeing it, and the library that had been clean became a little crowded, and it was a noisy crowd of people who wanted to know what was going on.

The surprise at this moment was that when Xie Shan saw the strange and mysterious light emitting from the small dots that were about to land outside the library window, the fear and anxiety in his heart disappeared, and it was replaced by an incomparable peace in his heart, which made Xie Shan and the crowd surprisingly quiet in an instant.

The glowing dot is finally about to hit the ground, and the destination of the dot is not the ground, but it begins to fly into the library through the window, and the straight direction points directly at everyone, and the target is actually the people in the library!

Xie Danyan saw that the glowing dots began to fly towards him, but there seemed to be a voice in his heart telling him not to worry, it was safe. The glowing dot eventually flew towards everyone's left wrist, and in the short time that everyone was being shocked by the light point that was rushing towards him, the light point attached to his wrist and transformed into a strange bracelet he saw.

After the bracelet glowed, a fan-shaped light screen formed in front of Xie Dan's eyes.
