Saturday.

Liu Fei is seventeen this year, and he is hard to force a college entrance examination candidate.

There is still half a year before the college entrance examination, and most of the students are studying hard, but Liu Fei is drowsy on the bus home.

I secretly went to the Internet café all night last night, and I never thought that I would fall asleep in the middle of the night, which is definitely a great shame for Liu Fei, who is nicknamed "Night King".

This situation would never have occurred before it was released, but for some reason, Liu Fei always felt as if he had forgotten something.

After eating two bites of steamed buns at the gate of the community, Liu Fei returned home weakly.

As soon as I entered the house, I saw a familiar figure.

"Da Fei, you're skipping class again!" On the sofa lies a playful girl with short hair, wearing a pink loungewear, boringly holding the remote control to change the channel.

Liu Fei paralyzed to the side and rolled his eyes: "There is a lot of, first reflect on why you are watching TV at home." ”

The girl is Liu Fei's sister Liu Rui, who is in her third year of junior high school this year.

Hearing him say this, Liu Rui also slumped into the sofa even more limply.

After a while, the two sighed in unison, and even their expressions were the same.

The bull pen of the school bully is different, but the sorrow of the school scum is always strikingly similar.

If the brother and sister still have something in common, that is, learning is really the same scum, and the scum is so bad that it doesn't matter if they go to school or not.

"Anyway, is it really good for high school juniors to be so casual?" Liu Rui glanced at Liu Fei, who was unhumanoid on the sofa: "If you can't even pass the junior college exam, the seven-day trip to the "Hades" you dream of will be useless." ”

"You've just gone to hell, what nonsense!" Liu Fei rolled his eyes.

"Brother, you look very handsome today. Liu Rui smiled like a little fox.

Don't look at this little girl's age, but with a belly of ghosts, Liu Fei has verified a truth with years of painful lessons.

When the little fox laughs at you, he can't even believe a punctuation mark!

Liu Fei took a sip of hot tea and squinted his eyes, but didn't say anything.

Hemp eggs, the water is so hot!

Liu Rui smiled and watched Liu Fei hurriedly spit out the tea, with a playful expression.

Liu Fei's tongue was still long, and he said vaguely: "There is something to say, there is a fart." ”

Oh, and I forgot to introduce it, the hammer is the stupid pug on the balcony who is chasing his own shadow in circles.

Liu Rui smiled: "I made an appointment with a friend to watch a movie today, Avengers 13, you give me some money." ”

Liu Fei's face was full of disdain: "My father and mother specially explained that it is forbidden for me to give you money, no way!"

"You don't say how they know. ”

"Don't even think about it, I'll sue you for blackness. Liu Fei turned his face like a book.

"Brother~" The little fox acted coquettishly.

"Speak normally! Giving money or anything doesn't exist, it doesn't exist in this life!" Liu Fei was righteous and awe-inspiring.

"Dead Liu Fei, don't think I don't know that you went to the Internet café last night again, see how your mother comes back and cleans you up!"

"It's a hundred dollars, go and go back quickly, don't play on the way." Liu Fei's speed of taking out the money flew up, and his face was full of spring breeze.

Strange to say, from today onwards I always feel like I've forgotten something important.

off?

Do I have that?

Liu Fei was puzzled, so he simply continued to lie down and buckle his mobile phone, if his parents didn't come back, he could stay in this position all day.

"If you can't think about it, you don't want to, my scarce brain cells have to be kept for playing games, and I can't waste it like this. Liu Fei was talking to himself while skillfully brushing up Weibo.

The recent headlines are all kinds of male celebrities cheating, and female celebrities tearing up...... There's nothing new at all.

"But I like it. Liu Fei smiled and clicked on a news that the head of the jade girl was unsubstantially ruled before her debut.

But looking at it, Liu Fei's face became more and more strange.

Did I not wake up, or did I go to some spoof site?

"The Taoist monk practiced at the company's headquarters, and a star lost millions of zombie fans overnight. ”

"The number of students in this year's college entrance examination is expected to exceed 50 million, and experts say that the expansion of the group of college students will raise China's basic combat strength to a new level. ”

"Recently, fifteen Nobel masters of the physics school jointly announced that the research of nuclear fusion will enable mankind to overwhelm the three races of sin, demons, and ghosts for the first time in the advanced tactics of mankind. ”

What is this?

Liu Fei sneered, turned off Weibo, but stopped again.

At this moment, he finally remembered what he had forgotten these days.

Three months ago, Liu Fei encountered heavy fog during a mountain climbing, and when he walked out of the mountain, he found that he suddenly returned to the way he was eight years ago, that is, when he was 17 years old.

After returning from running away for half a life, he was still a teenager, and it was difficult to explain how everything happened, and Liu Fei was in a state of confusion for the next three months, and he didn't wake up until the moment he saw the news just now.

Does it mean that Lao Tzu traveled through three months to wake up?

And back to seventeen?

Liu Fei hurriedly turned on his phone again.

The unrecognizable and familiar pages and news give a peculiar sense of immediacy.

It's not me who crosses over, it's the whole world that crosses.

Ten minutes, half an hour, an hour, two hours.

One piece of information after another is constantly refreshed, and the fragments are gradually combined into a clearer framework, and the appearance of the world begins to be restored.

Liu Fei's eyes were complicated, and it took a long time before he put down his phone.

This is a parallel world, except for similar backgrounds and similar cultures, there is no trace of that world in the other.

But the strange thing is that his relatives, friends and even classmates are still former classmates.

In this world, 65 years ago, the northern giant bear conducted a 100-million-ton nuclear test called "Super Ivan", which not only shook the earth, but also detonated the outer space corridor.

The aura surges, and the world recovers.

The first human psychic was created in the twelfth second of the revival of the aura, the first mathematical model of the aura was confirmed in the European laboratory eighteen hours later, and the first outer space passage "Lingxiao" was completely opened a month after the revival of the aura......

Immediately afterwards, the three races of sin, demons, and ghosts entered the earth from the outer space channel, and mankind retreated one after another.

It has been discovered that the awakening ability is so strange that it has no combat power other than to make humans more familiar with the aura, and the first five years are called the Dark Age in the face of terrifying creatures in outer space.

At this time, the master Luo Geng, who is known as the founder of the modern mathematical school, appeared.

At the exit of the outer space passage of the "Kunlun Secret Realm" in Huaxia, the master Luo Geng alone faced 500,000 demon disasters.

He directly defined the "spatial coordinate system" with the great power of matrix geometry, forming a 'four-dimensional storm' in space, and the outer space channel was temporarily cut off.

Only then did human beings discover that the root of their existence was the knowledge that human civilization has relied on to survive and be proud of since ancient times.

Learning can improve one's own strength, research can gain great power, and the more knowledge you have, the stronger your personal strength will be.

In this world, knowledge ...... It's really power!

The times have given scholars new meanings.

They not only continue to promote the progress of human civilization, but also shoulder the responsibility of defending human civilization.

Foreign enemies are eyeing each other, and the living space of human beings has been compressed to one percent of the previous one.

One after another, masters emerged one after another, using their physical bodies to fight against the three clans of the outer space, and win hope for the human race.

In the battle of the "Chaos" passage outside the space of the guilty family in Las Vegas on the North American continent, Johnson, the master of the "molecule" of the chemical school, solved the mystery of molecular movement, and the army of 200,000 sins was decomposed like dust in an instant.

In the battle of "Paradise Lost" in the outer space of Europe, the "mutant dengue implosion" of the biological "virus" master Amy Retz, hundreds of thousands of demons bled incessantly, and died tragically for three days.

But more often than not, humanity is still unable to fight against the three races of outer space.

Sin makes good use of people's hearts, and there are countless scum who betray the human race because of their temptation.

The gods of sin can crush the human masters in one-on-one, and only the supreme pioneers can fight against them.

The power of the demon scourge is extremely strong, from ants to ancient dinosaurs, and even creatures from the outer space, once infected by its blood, it will become crazy in an instant, and its number is even more numerous. Every time the demon calamity tide, human beings have suffered heavy losses, and two of the three outer spaces occupied by the demon calamity are located in China, and the Chinese civilization circle is also the area most affected by the demon calamity.

Ghosts are so mysterious and erratic that humans still don't fully understand their strength, and they don't even have a separate outer space. However, several undead natural disasters ended in the total annihilation of the human race, and it is still feared by the upper echelons of the human race.

Today's Earth has long since changed beyond recognition.

The continuous discovery of outer space has brought new hope to mankind.

After 60 years of development, human beings have completely occupied five outer spaces, the output of various mutated grains has reached a new high, and the stable safe area and a large number of resources have made the earth's population exceed 20 billion, and the population of China alone is nearly 3 billion.

However, the continuous oppression of the three races in outer space has made human beings on the earth only shrink into the defense circle of major cities and the outer space exploration area to survive.

The original comfortable life became like this, and Fei Ge was suddenly at a loss.

He walked aimlessly down the streets, only to realize that everything had really changed.

The billboard on the side of the road, the enrollment advertisement of Jianghua University, the little Taoist girl in the tight short skirt and green shirt robe, has sultry eyes.

Old man Xu, who sells steamed buns at the mouth of the alley, has sharp hands and feet, and he moves four or two thousand catties, and the dough is flying in the air.

At the construction site of the skyscraper, everyone was sweating, and a migrant worker calculated the mechanical formula with his left hand, and hundreds of bricks were easily lifted by his right hand.

Even if they can't become scholars, the humans of this world still have extraordinary powers due to spirit transformation.

At this moment, Liu Fei felt that his worldview was shattered.

Standing at the corner of the street where the prosperity is still but completely different from the memory, Liu Fei sighed softly.

If everything has changed, what's the point of going back to seventeen, is the familiar person still the person it used to be?

Liu Fei's expression was solemn, and he dialed the number in his mobile phone for a while.

The phone picked up, and a familiar voice came from the microphone.

"Dumbo?"

Is that person still familiar?

Everything about my past has become an illusion!

Liu Fei felt that his throat was a little blocked, his nose was sour, and he said softly: "Mom." ”

"Dead child, are you going to ask me for money again, tell you if you want money, you have to come and get it yourself! Look at the son of the old Wang family, who was third in the school last month, and then look at your uncompetitive appearance, even the feeling of fighting is not as good as other people's children......

Liu Fei: "???"

Liu Fei hung up the phone, he was sure that the person had not changed at all.
