Repeat students get up very early in the morning.
Because of reviewing the school's morning reading, some even started at 6:30.
In the early morning of summer, Liu Chang opened his sleepy eyes, woke up the fat man who was snoring and the glasses who had been reading novels all night last night, and went to the bathroom to wash up with the toiletries.
As for the good student Liu Tao, he has long since disappeared.
After washing up, Liu Chang walked to the door of the dormitory building, and saw the foggy sky at first sight.
It is reasonable to say that summer mornings are less foggy, but there have always been foggy days in the mornings in the past two years, and the fog in the past two years has always had a hint of pink, which will give people a strange feeling.
But any strange thing lasts for a long time, and it will make people feel familiar. Since the fog in the past two years has been this pink, and the weather forecast also said that this is just an ordinary "condensation nuclei" phenomenon, so, Chinese people who are used to eating waste oil, no one cares about this kind of thing.
Walking out of the dormitory building, Liu Chang submerged his body in the mist, and could smell the sweet breath in his mouth and nose.
Walked all the way through the fog to the classroom and started a day of study.
Drowsy, groggy.
The whole morning passed, and Liu Chang didn't know what he was reading, but he only remembered that he had been reading. He felt that this kind of day-to-day life was so boring that he wanted to die. He felt that everyone who lived a repetitive and monotonous life was a walking dead.
Liu Chang longed for something exciting, longing for some change.
Looking out of the window, the pink mist still hasn't dissipated, and the breakfast time is also passing in a daze. It's biology class.
Since last year, biology has inexplicably been stipulated as a compulsory course by the state—not just science. And the most amazing thing is that the score of biology college entrance examination is rigidly stipulated by the state as 200 points, which directly surpasses the number of Chinese and becomes the first course.
This is unexpected to everyone, but the rigid regulations of the college entrance examination also make the weight of the biology class suddenly more important.
But fortunately, Liu Chang still prefers biology, so he didn't take the first class so muddled.
"Today, let's revisit the compulsory test site of the college entrance examination - the Cambrian biological explosion."
"This is the scope of the test every year for the past two years, no matter how many times you review it, it will not be too much."
The speaker on the podium was the teacher who let Liu Chang and others sleep last night. He was very young, fair and clean, wearing a pair of narrow-rimmed glasses with black frames. He didn't talk much during the lecture, but he was able to get to the point.
"The Cambrian Explosion of Life is one of the top ten mysteries in the scientific world today. The classmate who was sleeping at the same table woke him up and asked him to answer what the Cambrian Explosion of Life was all about."
The biology teacher pointed to Liu Chang, who was taken aback for a moment, and then woke up his sleeping deskmate, Glasses.
"The teacher asked you a question, what happened to the Cambrian Explosion of Life?" Poking his glasses with his elbow, Liu Chang whispered the question to the teacher at the same table.
The dream was disturbed, Glasses stood up reluctantly, helped the glasses that were skewed due to lying down for too long, and rubbed the wrinkles on the face pressed by the clothes, and then muttered: "Chan Wu The explosion of life in the 1900s was probably hundreds of millions of years ago, a sudden evolution of life on earth. The evolution rate was hundreds of millions of times faster than before. It seems that there was no higher life before that, and suddenly there was after that. , it seems that all the existing species on the earth were produced during that period.”
"Hundreds of millions of years ago? What form did life evolve into? These are the test points, and you must remember the specific numbers." The teacher waved his hand and asked Glasses to sit down.
"However, your summary is not bad, but it is especially important to remember that during the Cambrian explosion of life, not only did all species evolve faster than the speed of light, but new species were also produced at faster than the speed of light. The ancestors of almost all current species were formed in that period, such as sponges, coelenterates, branched animals, leaf-pods, brachiopods, molluscs, arthropods, echinoderms, chordates, etc., etc., All species now arose in that era."
"Creation is amazing! The emergence of the Cambrian period is a strong evidence to refute Darwin's theory of evolution, and Darwin himself has always wondered about this matter."
"Teacher, are you questioning Darwin's theory of evolution?" A loud voice came from a corner of the classroom—it was Liu Tao, a good student.
"Uh, yes, why not?" The glasses teacher smiled and said, "The three levels of argument, nonsense-theory-law, Darwin's theory of evolution is just a theory, why can't you question it, you can also question it Well, not to mention that he himself questioned it."
"Since I'm here today, although it's not a test site, I'll mention it by the way. It's about the cause of the explosion of life in the Cambrian period."
"The current academic argument is that the earth suddenly produced a large amount of free oxygen, which led to the massive, widespread and rapid evolution of organisms, but I feel that this argument is also full of loopholes. How can oxygen What about allowing organisms to multiply and evolve at the speed of light?"
Just as the teacher on the podium finished speaking, the classroom suddenly became dark.
"What's going on?" Liu Chang looked out the window.
The fog outside the window suddenly thickened!
This is what causes the dimness.
The pink mist outside has not subsided since the morning, and now it has suddenly become thicker. Pieces of huge mist have filled the entire outside world, like a large piece of cotton stuffed into the entire world, blocking it. All exposure to light.
Perhaps it was because the mist was too dense, the originally pink mist gradually turned deep red, and then over time, it turned blood red at a speed visible to the naked eye.
The sunlight was completely blocked out, and the whole world turned into darkness.
Or to be more precise, the darkness was blood red, and the world turned black and red.
This weird color gives people a feeling of heart palpitations. Liu Chang turned his head and found that in the current classroom space, every student's face is black and red, and the facial features are blurred, which makes people palpitate.
If it was just dark, there might be noisy classmates yelling, or even naughty boys taking the opportunity to touch girls' butts, but in the current environment, no one dares to speak.
Because the world is dark, everyone has experienced it.
But the world is full of blood, and no one has seen it.
Every student saw the terrified expressions on other people's faces, no one dared to speak, and the whole classroom was silent.
"I'll go to the Office of Academic Affairs and ask to see what's going on?" In this solemn atmosphere, the biology teacher was the first to react.
After saying this, he opened the classroom door, melted into the blood-colored thick fog and disappeared instantly.
"Look, the fog is coming in." The fog is too dense and colored, so when it comes in through the cracks in the windows and the door, everyone can clearly see it.
Glasses sitting next to Liu Chang saw this scene and subconsciously covered his mouth and nose.
"It should not be poisonous, and even if it is poisonous, how long can you hold your breath?" Liu Chang saw the thick red mist floating in front of him, sniffed it with his nose, and smelled a strong fishy and sweet smell from inside.
"It smells weird!" The classroom has changed from the initial silence to the current noise. After the shock period, everyone started to discuss the strange weather.
"What the hell is this?"
"Thick blood-colored fog, I guess there will be a lot of car accidents outside."
"The fog is so thick that I can't see what's going on outside!"
"Make a call and ask about the situation at home." Liu Chang took out his mobile phone and dialed his mother's number.
He was answered with a busy tone—
"I can't make calls!" Liu Chang looked at the strange fog outside, and felt panic for no reason: "Could it be possible that this thing can also block the signal?"
"I'll go out to see the situation!" A bold student beside Liu Chang stood up and walked to the door.
And his action also attracted the attention of all the students. After he walked outside the door, everyone ran to the window to watch his situation.
The visibility outside the window was less than five meters, and the bold student had just stepped out before taking two steps before his figure was blurred.
"San'er, don't go any further, you won't be seen anymore." A classmate who was close to him shouted out the window.
"Oh! Okay, it's really red outside, you can't see anything, not even the teacher's office." "San'er" outside the door also shouted back, his voice pierced through the fog, forming a small circle small ripples.
Then...
Another ripple echoed in the air, and a group of small sparrows rushed through the thick fog in the direction of the sound source.
"Shua" sound -
The usually timid sparrow was as brave as a bomber at this time, crashing into the cheek of "San'er" at a fast speed.
Paji!
When the first sparrow came into contact with "San'er"'s face, it made a strange sound like a smashed tomato, and then the strange "pop" sound continued continuously.
Liu Chang opened his eyes and saw that "San'er" was pierced by the sparrow's sharp beak after the first short scream, and then was swarmed up by the sparrows that followed. In less than a moment, his entire face was ruined into a rotten watermelon.
"ah!"
San'er screamed loudly, and was pushed down to the ground by the successive impacts.
However, his screams lasted for a short time, and then his trachea or mouth may have sucked his own flesh and blood, and the "San'er" lying on the ground could no longer make a loud cry, only "" cluck" sound.
And those usually docile sparrows, in the sound of "clacking", pecked at the fresh flesh and blood on the spot.
The classroom was really shocked and terrified this time, and all the students were terrified.
Even in horror movies, they have never seen such a terrifying scene.
The classmate who was still alive and kicking just now was wriggling on the ground, and the usually timid sparrow was doing the most bloodthirsty thing. At this moment, no one dared to go out to stop the group of sparrows, or in other words, no one in the panicked crowd thought of this.
Everyone was dumbfounded.
It wasn't until the satiated sparrows flew away and the people on the ground stopped wriggling that no one came back to their senses.
"Who can tell me what's going on?" Standing next to Liu Chang, Glasses muttered to himself like a fool.
