Chapter 2

The morning of repeat students is very early.

Because of reviewing the school's early reading, some even started at 6:30.

In the early morning of summer, Liu Chang opened his sleepy eyes, woke up the snoring fat man and the glasses who read novels all night, so he took the toiletries to the bathroom.

As for Liu Tao, a good student, he has long been gone.

After washing up, Liu Chang went to the door of the dormitory building and saw the misty sky at the first sight.

It is reasonable to say that there is less fog in the early morning of summer, but in the past two years, there are always foggy days in the morning, and the fog in recent two years always has a trace of pink, which gives people a strange feeling.

But any strange thing lasts for a long time, it will make people feel strange. Because the fog in the past two years has been pink, and the weather forecast also said that this is just an ordinary "condensation tuberculosis" phenomenon, so no one cares about this kind of thing for the Chinese who are used to eating gutter oil.

Out of the dormitory building, Liu Chang submerged his body in the fog, and smelled the sweet smell in his mouth and nose.

All the way through the fog to the classroom, began a day of learning.

Drowsy, drowsy.

As the morning passed, Liu Chang did not know what he had read. He only remembered that he had been reading it. He felt that this day-to-day life was so boring that he wanted to die. He felt that everyone who lived a repetitive monotonous life was a walking corpse.

Liu Chang is eager for something exciting and eager to change.

Looking out of the window, the pink fog still does not dissipate, breakfast time is also in a daze in the past.

In this way, the first class began.

It's biology.

Since last year, biology has been prescribed as a compulsory course by the state, regardless of Arts and Sciences. What's more, the score of biology college entrance examination is strictly set at 200 by the state, which directly exceeds the number of languages and becomes the first course.

This is unexpected to everyone, but the rigid requirements of the college entrance examination also make the weight of biology class suddenly become particularly important.

Fortunately, Liu Chang still likes biology better, so he didn't have such a muddle in the first class.

"Today, let's review again the required test point for the college entrance examination: the Cambrian biological explosion."

"This is the scope of examination every year in the past two years. No matter how many times we review, we can't go too far."

On the platform was the teacher who let Liu Chang and others sleep last night. He was very young and white, wearing a pair of black framed narrow rimmed glasses. He didn't talk much during the lecture, but he was able to cut into the theme.

"The Cambrian explosion of life is one of the top ten puzzles in the scientific community today. The classmate who was sleeping at the same table called him up and asked him to answer how the explosion of Cambrian life was."

Biology teacher pointed to Liu Chang next to, the latter a Leng, and then woke up the sleeping table glasses.

"The teacher asked you a question, what was the Cambrian explosion of life?" With his elbow poking glasses, Liu Chang told the teacher's problem in a low voice.

When the dream was stirred, the glasses stood up reluctantly, helped the glasses that had been tilted for a long time, and rubbed the folds on his face which were pressed by clothes. Then he murmured: "the Cambrian explosion of life, maybe hundreds of millions of years ago, was a sudden evolution of life on earth. The speed of evolution is hundreds of millions of times faster than before. It seems that there was no higher life before that, and then suddenly there was. It seems that all the existing species on the earth were born in that period. "

"Hundreds of millions of years ago? What form did life evolve from and why? These are all test points. Remember the specific numbers. " The teacher waved his hand and let the glasses sit down.

"It's a good summary, but it's especially important to remember that during the Cambrian explosion of life, not only did all species get faster than light speed evolution, but also new species were produced at superluminal speed. Almost all the ancestors of modern species were formed in that period. Sponges, coelenterates, gill tracts, leafpods, brachiopods, molluscs, arthropods, echinoderms, chordates, etc., were formed in that period. Now, all species were born in that era. "

"What a wonderful creation! The emergence of the Cambrian 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?" In one corner of the classroom, a loud voice came out - it was a good student Liu Tao.

"Well, yes, why not?" The glasses teacher laughed and said, "there are three levels of arguments: nonsense - Theory - law. Darwin's theory of evolution is just a theory. Why can't you question it? You can also question it, not to mention his own question."

"Now that I've talked about it today, although it's not a test site, I'd like to mention it. It's about the Cambrian explosion of life. "

"Now the academic argument is that the earth suddenly produced a lot of free oxygen, which led to the massive, universal and rapid evolution of organisms, but I feel that this argument is also full of flaws. How can living things reproduce and evolve at the speed of light if it's just oxygen? "As soon as the teacher's words on the platform came here, the classroom suddenly darkened.

"What's the matter?" Liu Chang looked out of the window.

The fog outside the window suddenly became thick!

That's what makes it dark.

The pink fog outside has not subsided since the morning, and now it has suddenly become strong. A huge piece of fog fills the whole outside world, like a large piece of cotton stuffed into the whole world, blocking all the light.

Perhaps because the fog is too strong, the original pink fog gradually turned into a deep red, and then over time, with the naked eye speed into a piece of blood red.

The sun was completely blocked out, and the whole world turned into darkness.

Or, to be exact, with blood red in the dark, the world turned black and red.

This strange color gives people a feeling of palpitation. Liu Chang turns his head and finds that in the space of the classroom, every student's face is black and red, and his facial features are blurred, which makes people feel frightened.

If it's only dark, there may be noisy classmates shouting, and even naughty boys may take the opportunity to touch girls' buttocks, but no one dares to speak in the current environment.

Because the world is dark, everyone has experienced it.

But the world is so bloody that no one has seen it.

Every student saw a look of panic on the faces of others. No one dared to speak. The whole classroom was quiet.

"I'll go to the dean's office and see what's going on?" In this dignified atmosphere, the biology teacher was the first to react.

He put down this sentence, opened the classroom door, melted into the bloody fog, and disappeared instantly.

"Look, the fog is coming in." The fog was so thick and colored that everyone could see it clearly when they came in through the windows and the door.

Sitting next to Liu Chang's glasses to see this scene, subconsciously covered his mouth and nose.

"There should be no poison, and even if it's poisonous, how long can you keep it off?" Liu Chang saw the red fog floating in front of him, sniffed it with his nose, and then smelled the rich smell of sweet smell from inside.

"It has a strange smell!" The classroom has changed from the initial quiet to the current noise, everyone after the panic period, began to discuss the strange weather.

"What the hell is this?"

"Bloody fog, I guess there are a lot of accidents out here."

"The fog is so thick that you can't see what's going on outside!"

"Call and ask about your family." Liu Chang took out his mobile phone and dialed his mother's phone.

Responding to him was a busy tone -

"the phone can't be made!" Liu Chang looked at the strange fog outside and felt a panic for no reason: "can this thing still block the signal?"

"I'll go out and see what's going on!" Liu Chang side of a bold student, stood up and walked to the door.

And his action, also attracted the attention of all the students, he walked outside the door, everyone ran to the window, looking at his situation.

The visibility outside the window is less than five meters. The bold student just came out and did not take two steps, his figure became blurred.

"Saner, don't go any further. If you go further, you won't be able to see you." A classmate close to him called out the window.

"Oh! OK, it's so red outside. You can't see anything. You can't even see the teacher's office. " "Saner" outside the door also called back, his voice through the fog, forming a small ripple.

Then

Another ripple came from the air. A group of small sparrows rushed through the thick fog and rushed in the direction of the sound source.

With the sound of "boom" -

the usually timid sparrow is as fierce as a bomber and bumps into saner's cheek at a great speed.

Crack!

When the first sparrow and "saner" face contact, it makes a strange sound like breaking a tomato, and then the strange sound of "pa Ji" continues to rise.

Liu Chang opened his eyes and saw only that "san'er" uttered the first short scream, and his whole face was pecked through by the sharp beaks of sparrows, and then swarmed on by the following flocks of birds. Within a moment, his whole face was turned into a rotten watermelon.

"Ah

The third son screamed loudly, and people were pushed to the ground by successive shocks.

However, his scream lasted for a short time, and then his blood and flesh might be sucked into his trachea or mouth. The "saner" lying on the ground could no longer make a loud cry, only the "clucking" sound vomited out of his throat.

And those usually docile sparrows, in this "cluck" sound, on the spot pecked up those fresh flesh and blood.

The real shock in the classroom, fear, all the students are scared silly.Even in horror films, they have never seen such a horrible scene.

Just now the students who were still alive and dancing were wriggling on the ground. The usually timid sparrow was doing the most bloodthirsty thing. At this moment, no one dares to go out and stop the sparrows, or, in a flustered crowd, no one wants that.

Everyone was scared to death.

Until the full sparrows fly away, until the people on the ground stop wriggling, no one comes back to God.

"Who can tell me what's going on here?" Standing next to Liu Chang, glasses are muttering to themselves.
