Yang Yi only felt that an incomparable bright light flashed in an instant, and his eyeballs immediately lost their ability to distinguish colors, leaving only a piece of white.

Then there was an earth-shattering explosion in my ears.

The furious energy suddenly acted on Yang Yi's whole body, and his brain lost consciousness with a bang.

This strong light was even more dazzling than the planet that Yang Yi burned in the four-dimensional space, brighter and more violent, and it was simply beyond it.

Even when Yang Yi was about to leave the four-dimensional space and the burning star exploded, the surge of energy was not so terrifying.

The energy released by antimatter weapons at the moment of material annihilation is 100 times more powerful than that of a hydrogen bomb, and the temperature is as high as tens of memories.

The range of energy enveloping, not to mention life, any metal known to man will vaporize in an instant.

And whether Yang Yi, who is in the heart of the explosion, can survive, only God knows.

"Poof!" I don't know how long it has been, but a bright light seems to have flashed wildly in Yang Yi's brain, as if he was in a dream. In the haze, Yang Yi came to a place where flames were burning everywhere.

Yang Yi didn't know what this place was, and he didn't know how he got here.

Through the blazing white flames, Yang Yi saw his parents who he thought about day and night. I saw my parents working in the Beacon Space City in the past, and spent their childhood time with them.

"Xiao Yi, that's the home earth!" The mother, who was wearing a Chinese blue spacesuit, took Yang Yi's little hand and pointed to the blue earth above the space city and said softly.

"Mom, the earth is so beautiful!" Yang Yi childishly pulled her mother's hand and said.

"Don't worry, where will your parents send you to study next year!" The handsome face of the father, who was holding Yang Yi's other hand, grimaced at Yang Yi, and smiled at his gentle and beautiful mother.

"Really? Daddy, I want to go to that blue star! Yang Yi looked up at the blue earth that was swaying outside the space city, full of yearning.

"Of course it's true, how could Dad lie to you." Mom looked at Yang Yi gently.

"Xiao Yi, look, the sun is out!" Dad pointed to the sun-facing side of the space city with the pointer light, the egg-sized sun on the black canopy.

"Dad, the sun is so small, much smaller than the blue earth, can he grow up?" Yang Yi's little head tilted and asked mischievously.

"You'll grow up, and when you grow up, the sun will grow up together!" Mom stroked Yang Yi's forehead and said softly.

"Mom, when I grow up, I'm going to buy a birthday gift for the sun, thank him for growing up with me!" Yang Yi said innocently.

"Silly boy!" Dad patted Yang Yi's head and smiled.

A family of three stood on the observation deck of the Beacon Space City, with the dark and boundless universe outside the transparent glass window. In the dark sky in the distance, countless stars sparkle like diamonds set in black satin.

The sun hung high above the canopy overhead, like a night lamp, bright and dazzling.

The blue earth and the huge gray moon are like twin sisters, holding hands and snuggling up, so close.

"Poof!" Another ray of bright light flashed in Yang Yi's brain, and the nerves in Yang Yi's brain seemed to twitch, and the picture in the dream world switched to a white spaceship returning capsule that went back and forth between the space city and the earth.

"Xiaoyi, sit tight!" The father who piloted the spaceship. It was the mother who spoke, and the mother was sitting next to Yang Yi.

"I'm a little scared, Dad." As the spacecraft left the indicator light and entered the dark space, Yang Yi glanced at the blue earth above his head, and then looked back at the indicator light behind him that gradually disappeared from sight and said.

"Don't be afraid, soon we will reach the earth, and you will know a lot of friends, like you, who were born in the Beacon Space City, the earth is very welcome." Mom said with a smile.

"Really, it's so fun!" Yang Yi seemed to forget his fear in an instant, and said happily.

"Dad, the earth is so blue, so big!" The dream picture has reached the sky above the earth, and is about to pass through the atmosphere, Yang Yi, who is tied to the seat, is so nervous that his face is flushed, so he tightly holds his mother's hand and says excitedly.

"Poof! Burst! Two more bright lights flashed through Yang Yi's brain, and the nerves in Yang Yi's brain twitched a few more times.

The picture in Yang Yi's dream is that in a junior high school physics class on Earth, the physics teacher is explaining the law of gravitation and Einstein's theory of relativity.

The holographic video area is playing a picture of the light space city flying over the earth with a huge solar sail, and the teacher points to the huge body of the space city and says:

"This is the application of Newton's gravitational force in reality, under the action of the gravitational force of the planet, artificial vehicles can also fly around the planet at a constant cosmic speed."

Then the video screen shows the surface of the sun burning, and the teacher points to the huge sun and says, "According to Einstein's theory of relativity, massive objects will bend space-time, and due to the huge gravitational attraction, time will slow down due to the attraction of gravity."

The greater the mass, the greater the degree of space-time curvature, and the more obvious the gravitational attraction will be.

When the mass increases to a certain critical value, gravity dominates everything, constantly swallowing up nearby matter, forming dense white dwarfs, neutron stars, or black holes that swallow everything.

When a black hole is formed, anything close to its gravitational field will become a meal for the black hole, and nothing will escape, not even the light traveling 300,000 kilometers per second in the universe, and time will stop there. ”

Yang Yi in the dream looked thoughtfully at the image of the Beacon Space City, and couldn't help but feel a sense of pride in his heart, and he went deeper into the teacher's explanation.

Not only did he live in Beacon Space City, but his parents still work there.

Suddenly, the picture in Yang Yi's dream was pulled to the burning place, and all the pictures became violent, as if he saw the burning beacon Space City, and saw his parents who died together with the Space City in an instant.

The moment when I saw my parents still fearless and smiling kindly in the burning fire.

"Poof...... Burst...... Poof....." A few more flashes of bright light flashed, and Yang Yi's cranial nerves twitched several times in a row, and his mind gradually cleared.

"Am I dead?" After a few more minutes, Yang Yi slowly woke up in the dream, and at this time, Yang Yi, whose memories before the explosion had all recovered, muttered to himself.

Long.

Yang Yicai opened his eyes with difficulty and subconsciously glanced around.

Finding something in the hazy eyes and gradually becoming clearer.

It seemed that his eyes were not blind, and thinking of the bright light that occurred at the moment of the explosion, Yang Yi shuddered with palpitations.

"I'm here!" Yang Yi opened his mouth and shouted, he clearly heard his own shout, and his ears were not deaf.

"Haha, I'm not dead, I'm still alive!" Suddenly, after confirming that he was really alive, Yang Yi stood up in the groping and let out an excited and crazy laugh.

I can't help but feel a sense of pleasure in my heart for the rest of my life, and I can survive the catastrophe.
