Hey, it's just that Professor Liu didn't have to stab out quickly, another black shadow had already struck out of him in advance, and a black blade pierced out of the professor's hole, and Professor Liu fell to the ground without any suspense, booming, and the black fireball instantly crushed over him. Pen ~ fun ~ pavilion www.biquge.info

A person who was still alive just now turned into scorched earth in an instant, whether it was a dozen or a dozen students who had just graduated, or Jiang Lao, they couldn't accept the fact in front of them.

"Professor, Professor....." Cheng Jun and his classmates choked up at the same time, but the reality is so cruel.

And the corners of Jiang Lao's face only spasmed slightly, and the situation in front of him no longer allowed him to think about it, the white-haired old man seemed to have made a decision, and a white light rushed out in his hand.

In the boundless darkness, it seemed that a wisp of moonlight was falling, reflecting a star shining, causing the people in black to pause for a short time, and the whole world was frozen in seconds.

The man in black was shocked, "What?

Boom, Yuehua seemed to have an attraction, instantly absorbing Cheng Jun and more than a dozen graduates, a white feather like the Northern Lights, as if it could pass through the power of the wilderness, penetrate the enchantment of the man in black, like entering a no-man's land, in the night sky like a meteor, and disappeared in front of the two in a blink of an eye.

"Hmph, old immortal! You really left your hand!" the man in black was very annoyed.

"Stop it! ordinary people within a radius are innocent!" Although Cheng Jun and the others fled from this place for the time being, the old man watched the black fireball roll bigger and bigger, his eyes became more solemn, and his face was full of sadness.

"Haha, you all have to bury him for ......"

"Who?"

"Old thing, let's all die, I'm too lazy to talk nonsense with you!" The black-clothed man's eyes were full of ruthlessness and coldness, and his fingers flicked, and the black fireball rumbled violently.....

Before they had time to say goodbye to their relatives and friends, Cheng Jun and a dozen classmates evaporated from the world; they didn't know that the moment they left, the place exploded, and a huge crater and a sea of fire exploded in the middle.

Thick smoke billowing around, like the end of the magic city, terrifying mushroom clouds rose in the sky, tongues of fire were like pieces of fireworks, hundreds of people died, I don't know how many people lost contact, thousands of people suffered from bad luck, and the whole country was saddened......

And a little more than a month ago, at the other end of the West, a National Aeronautics and Space Administration (NASA) announced the discovery of Kepler-452b, the exoplanet most similar to Earth to date, and said that "astronomers are close to the goal of thousands of years of dreams - the discovery of another Earth." ”

Looking back at the Earth from outside the solar system, the Earth is like a speck of dust floating in the vast galaxy of the universe, a dull blue dot, equivalent to a drop of water in the Pacific Ocean.

Many scientists have turned their eyes and thoughts to the quiet and brilliant starry sky, and it is very likely that there will be planets in the universe that are very similar to the Earth's environment, or they may give birth to life, or even have a higher level or another civilization?

Kepler-452b is located in the constellation Cygnus, about 1,400 light-years from Earth, which is equivalent to a beam of light emitted during the Tang Dynasty, and has only just arrived on Earth.

One idea of scientists is to use the warp speed spaceship, that is, in the science fiction movie "Star Trek", to use the "transformation" of space to propel the spacecraft forward. The same is true in the movie "Avatar", which only takes a few weeks to fly from Earth to Pandora.

But even at the speed of a warp spacecraft, it would take more than six years to reach Kepler-452b, 1,400 light-years away.

Later, the wormhole presented in the science fiction movie "Interstellar" was the most convenient way to travel the stars.

The vast cosmic galaxy passes through the space-time tunnel, and the wormhole directly connects the two points in space-time. The famous physicist Stephen Hawking once proposed that wormholes are all around, but they are too small to be seen by the naked eye, and they exist in the cracks between space and time, and even "so small that humans cannot pass through".

Many people speculate that one day, we may be able to grasp a wormhole and enlarge it infinitely, or we may be able to build a huge time tunnel. Going to an extraterrestrial planet through it can be as convenient as taking a bus or subway.

But all of the above are just assumptions and assumptions of some scientists, at least for the time being, so far away that human beings may not be able to reach it in this life and this life, and more people think that it is too unrealistic!

It's just that, no matter how bizarre, there seems to be an invisible hand everywhere in heaven and earth, whether it is the astronomical world, or the investment and other worlds, many things, always feel very far away from us, but perhaps, one day, he is by our side, but you don't know his existence!

Just as a group of scientists from various countries raised all kinds of questions about the existence of life on the second earth and the space-time tunnel, a month later, the astronomical monitoring staff of a certain country was very shocked to find that in the eastern time and space of Shenzhou, a swan-like white light practice, like a star aurora, crossed the night sky, and there were more than a dozen life forms on it.

The speed of white light and shadow is extremely fast, far exceeding the speed of light, and it disappears one by one, leaving only a few afterimages in space, and is flying in the direction of Kepler-452b, as if it has opened a space-time tunnel in an instant, and it will reach the Kepler-452b field in more than an hour, and disappear into a vague void.

“oh，mygod!” The eyes of all the members of the astronomical monitoring room widened, and they couldn't believe that this was the truth. Like a wood carving clay sculpture, staring at the monitoring screen motionless for a long time, everyone was shocked beyond measure!

It wasn't until Bai Xinglian's shadow disappeared—the blurred sky above the 452b realm that they came back to their senses in a daze.

"God, what did I see? It's just an afterimage, but I'm sure it's a holy white swan!"

"Hell, it took just over an hour to get from Earth to Kepler-452b!"

"1 hour and 18 minutes to be exact!"

"Could it be that there really is another kind of space-time tunnel?"

"There's still a life in there?"

The white light practiced shadows, crossing the void, making the entire monitoring room boil all at once.

"The vast universe, the boundless starry sky, maybe the earth is indeed not the only source of life, all things dominate, human beings may not be lonely, the brilliant galaxy, and the earth is not a lone star of life!" A retired orientalist knew about this, and when he said this, he quickly shocked the astronomical circles of various countries, but ordinary people did not know about it......

On the other side of the cosmic galaxy, Cheng Jun and a dozen classmates were stunned the moment Bai Yu crossed the river galaxy, and everyone fell on the fragment of a huge five-color roulette wheel. A white feather silently submerged into Cheng Jun's palm.

The fragments of the five-color roulette wheel diffused red, yellow, white, black, and blue multicolored circles, and the layers of aperture obviously carried energy fluctuations, causing waves of ripples, and many ancient characters emerged, emitting a few wisps of green light, like the energy of life caressing everyone's face.

Cheng Jun was the first to wake up, and the moment he opened his eyes, he saw a strange brilliance of the fragments of the five-color roulette wheel fading, and before he could quickly observe the surrounding situation, he woke up all his classmates one after another, including him, a total of 18 people.

"Cheng Jun?" Yi Lu approached Cheng Jun closely, very nervous and uneasy.

"Where is this?" all of them had a bad premonition, and when they looked around, they couldn't see clearly, and they were in chaos and darkness, and they didn't know where they were.
