In the cosmic starry sky of thousands of trillions of light years, a huge star has finally completed its last mission, the core undergoes high-speed nuclear fusion, but the increase in the mass of the element has made it a giant star, about to annihilate, becoming a new black hole, but this is not the end, around this star, there is also a black hole with a mass close to infinity, the two black holes collided at this time, merged, and then produced gravitational waves......

The famous scientist Albert Einstein once predicted the existence of gravitational waves through the general theory of relativity, because he introduced the concept of limited propagation speed of interaction, gravitational waves cannot exist in Newton's classical theory, but this does not mean that gravitational waves do not exist, and the energy generated by the merger of these two supermassive black holes is also huge, enough to distort space-time, and scientists also happened to seize this opportunity to successfully detect this gravitational wave with a detector.

However, the detection of gravitational waves is definitely not accidental, gravitational waves may be generated anytime and anywhere in any time and space in the universe, but what is detected is such a powerful one, the energy of gravitational waves is too dense, and there is a tremor in space-time at a certain location in the depths of the universe, it resonates with the earth light years away, and the incredible thing is quietly happening.

At that time, on the earth, in the room of a unit building, a teenager was concentrating on reading a book, the book was a little yellow, and he had been thinking about using it for some years, the boy was about 20 years old, with a beautiful face, his hair was combed high, and he looked a little non-mainstream, wearing a clean shirt, and he was a college student.

"Knock knock! Can I come in? Outside the door was the shout of a middle-aged woman.

"Yes!" The boy replied impatiently.

The middle-aged woman who pushed the door in was very temperamental, or well maintained, the years did not leave too much on her face, she was wearing a gorgeous long dress, her eyebrows were a little upturned, the color was darker, she was standing at the door with her waist crossed, and suddenly a momentum was coming, she was wearing a long skirt, striped and intertwined, and her legs were separated like a slight breath during military training, from an angle, it looked like a big compass, ready to draw a circle at any time. She is the mother of a teenager, and she is the head of personnel in the unit, and she is a strong woman.

At this time, she saw that the teenager was reading a book, and it seemed a little surprised, usually, the teenager should be playing lol on the computer, accompanied by the high-frequency clicking sound of the mouse, and the computer screen is a high-frequency switching lens, every time the teenager goes home, in addition to eating, he will play the game, sometimes the network is not good, and he will rush out to lose his temper, in the eyes of outsiders, he is almost more dedicated than a professional player, but this is such a situation, he was actually found reading a book. The middle-aged woman walked over and looked at the cover of the book, it was not a computer level 2 and English level 4 information book, but the vernacular version of "Romance of the Three Kingdoms" that she bought for him when he was in elementary school.

"Why don't you play a game, this sun is coming out of the west."

Or curious, the middle-aged woman deliberately sarcastic, and at the same time her hands were not empty, she was very skilled in wiping the dust off the desk, bedside table and other furniture, and then walked over to pick up the mop next to the door to mop the floor.

"Why do you have to nag me when I play games, and if you don't play, you also have to ask, what should I do?"

The boy was a little angry, he didn't play the game for a reason, because he accidentally touched the router, which led to a temporary network disconnection, and the game was over when he logged in again, and the four teammates collectively reported him, so he was honorably punished for half an hour, of course he couldn't tell his mother about this reason, and he didn't know why, he just wanted to read the book, and it happened to be "Romance of the Three Kingdoms". But he didn't see it, most of it was just a show.

The middle-aged woman didn't say anything more, and after finishing what she was doing, she casually closed the door.

Looking at the middle-aged woman leaving, the young man was thoughtful, and soon something magical happened, the "Romance of the Three Kingdoms" in his hand began to turn the page automatically, I don't know how long it took to turn the page, the page returned to the first page, and stopped. The boy looked at the page and could see the beginning of the book, "Speaking of the general trend of the world, it will be together for a long time, and it will be divided for a long time." The other words were actually gone, and for a long time a dazzling yellow light shot into the book, and the book began to swell, becoming 10 times the original size, and the surrounding things began to fade, all of which were a little sudden, and the boy didn't even have time to think about what was happening, just like that, the book broke away from the boy's hand, rose into mid-air, and began to rotate, faster and faster, when the boy felt that the book was spinning into a circle, the rotation gradually stopped, and he saw a beam of bright light shining into the air, forming a strange pattern, The pattern connects a huge spatial tunnel.

All this happened too suddenly, the boy thought he was dreaming, so he pinched his thigh fiercely, and found that the pain was very clear, he remembered the verification method in the inception, and took out a toy spinning top from the drawer, and turned it on the ground, as long as the spinning top did not stop, then he was in a dream, but the boy was disappointed, and the spinning top quickly stopped.

Since this is not a dream, there must be a reasonable explanation for what happened.

The boy began to mumble, looking around, and found that the layout of the room had already changed, and now he was in a dark space, and all he could see was a shiny book, a pattern, and a spatial tunnel.

"You must be weird, Yuyi!"

I don't know where the voice came from, the young man was a little blind, but the voice exuded a majesty, and it was carefully distinguished that it was an old man.

"Who are you, what do you mean by making my house like this?" Yu Yi inquired tentatively, and at the same time judged the direction of the next sound, hoping to find the old man who made the sound.

"Do you know about the people of the Great Destiny?"

"What the hell are you doing in the hole, come out quickly!" Yu Yi finally judged the old man's location, but he didn't dare to approach the spatial wormhole rashly.

"Do you know the name of Donghua Shangxian?"

"I don't care what kind of immortal you are, this is the twenty-first century, and if you pretend to be a ghost like this, I'm not polite to you!" Yu Yi was enraged by the barrage of questions.

"Hmph, if it weren't for that gravitational wave in the depths of the universe, I wouldn't be here?"

"What does this have to do with gravitational waves?"

"To put it simply, it is the gravitational waves that make the time and space I am in resonate with your time and space, the space is distorted, there is a crack, if it is not repaired in time, then the two time and space may collapse at the same time, according to the prophecy of the ancient book, there is a person of great destiny who will save all this, so I appeared here."

"You're saying I'm the one you're looking for?"

Yu Yi laughed out loud after hearing this, and said with a smile: "You must have found the wrong person, I am the king of the game, I am a very introverted person in real life, I will blush even when I go on stage to speak, you better don't waste time, go back quickly." ”

"I'm not sure, but when you guide here, you naturally have his reason, up!"

With the old man's shout, the suction of the spatial wormhole increased sharply, Yuyi was sucked into the hole, and the room returned to light, except for the people who were gone, the curtains were swinging there, and everything was as usual.
