"This math problem is very simple, we use the formula to find the slope directly......"

Dadada,

The teacher's chalk swam rapidly on the blackboard, drawing white lines, and the process and ideas of solving a math problem were quickly revealed.

call

Well~

Hah-

Under the small podium, the students held their heads with their hands, their eyelids unconsciously drooped downward, their heads were groggy, and the words of the teacher on the podium were blowing in their ears like the wind, and the listeners wanted to sleep.

The sound of falling leaves outside drowned out the sound of strokes on the blackboard, and the teacher's mouth opened and closed, like a fish in the water spitting bubbles, and the eyes flickered and dimmed, and there was a blur.

Bang –

A classmate's head in the back row had a close contact with the desktop, and there was an extra red mark on the door of his head, and then the whole class was stunned, looked at the classmate in shock, and then sighed heavily.

The classmate shook his head, and he didn't know what to say, shook his head, picked up the book in his hand, looked at the teacher apologetically, and intuitively stood in the empty space behind.

This is the easiest and most direct way for them to overcome their drowsiness.

The math teacher turned his head to look at it, shook his head helplessly, sighed, broke the tip of the chalk in his hand and threw it into the trash, and tapped the blackboard hard.

"Come,

Students, let's continue this question! ”

It's already autumn, and the students in the third year of high school are about to hit next year's deadliest college entrance examination, for this opportunity for the carp to jump over the dragon gate, the top and bottom of this high school are full of nervousness, and even when sleeping, someone will wake up because of this.

......

"It's almost time for the college entrance examination."

Cao Qin sat at the door, from which he could see people coming and going on the playground, and this autumn, there were obviously fewer people on the playground.

"College Entrance Examination...... Is it important? ”

Jiang Dong was wearing a security uniform, holding a pack of instant noodles in his hand, and chewing in his mouth, there were so many of these things that he simply used them as snacks for pastime.

He didn't need such a thing as the college entrance examination, and if he hadn't come to this high school for an internship, he might not have entered a high school in the human realm to learn about these things.

"It must be important, this exam basically determines your future level of life, whether you will eat meat or vegetables in the future, this exam will be for life!"

"It's so serious, one exam can condemn a person to death?"

"Not necessarily, but there will be a lot of variables in the future, the college entrance examination is the test that can best reflect a person's ability, and most people's future lives have decided the starting point and end point during the college entrance examination."

"That is, there are still variables, what are you doing with so much pressure."

"A volume of scriptures, a thousand pounds of pen and ink, life always has to cross the mountain, this is the system of people in the old world, screening and survival of the fittest is the only way in life, the college entrance examination is the original mountain."

"It's so serious, you can lose your life."

"You always talk about life and death, but people don't just have the pressure of death."

See explanation is not clear,

Cao Qin simply waved his hand, stopped fighting with the stubborn guy next to him, moved the maza, and changed it to a place with more sunlight.

Jiang Dong chewed the instant noodles in his mouth hard,

He still doesn't understand, can this book and a pen still force people to die, and there is something more desperate in this world than death?

Seeing that the instant noodles have bottomed out,

Jiang Dong came to the trash can on the side of the road, raised his hand, and threw all the bags and seasoning bags into the trash can.

clapped his hands,

Jiang Dong raised his head and straightened his waist.

Well?

Cloudy?

Jiang Dong looked at the sky above his head that was gray, and the black fog like a dark cloud directly covered most of the sky of the entire school, and the sky instantly darkened.

Take a few steps forward,

Jiang Dong sniffed it, and there was a trace of fishy and unpleasant smell in the air, and the strange smell was mixed with the unpleasant smell of rust.

It's the breath of dark energy!

Jiang Dong's eyes instantly flickered, he took a few steps back, and looked at the sky vigilantly.

Dark energy?

So much!

Subconsciously Jiang Dong wanted to summon the Void Breaking Knife, but the aura here made him feel very uncomfortable and even had a feeling of suffocation.

But the moment the black wooden box came out, he regretted it a little.

This is the school, and there are still a lot of students playing in the school playground, showing their weapons in front of everyone, so he Jiang Dong doesn't want to mix in this school.

While thinking about countermeasures, Jiang Dong quickly ran towards Cao Qin's position.

Ordinary people should not be able to feel or touch this dark energy, but Jiang Dong knew in his heart that the sudden appearance of this power was definitely not a good thing, at least for now, there should already be monsters hatching in this black cloud.

"Cao Qin, Cao Qin!"

"Shout what? I'm here. ”

"Look at the heavens...... Heavenly ......"

Jiang Dong ran very fast, he didn't take a breath when he spoke, his face was flushed, and he could only beat his chest with one hand, and pointed to the sky with the other, signaling Cao Qin to look over.

"Oh, it's a dark cloud."

Cao Qin touched his head and said indifferently: "It seems that it hasn't become a climate yet, so it's okay to destroy it." ”

"Sabotage? How to destroy? ”

Jiang Dong looked at Cao Qin, why did this guy still look light, he was very nervous now, the clouds formed by that dark energy would be more and more, more and more, and with the increase of the existence time, the internal creatures would gradually hatch one by one.

The main thing is that

That thing is floating in the sky, it can't be touched or touched, how to deal with it?

"Speaking of which, I haven't taught you anything in the past few days since you've been here." Cao Qin straightened the security uniform on his body, came to a place that no one could see, and said, "I'll show you a hand today, so that you can reacquaint yourself with the position of inspector." ”

Wow –

As he spoke, the shadow behind Cao Qin began to melt, and the shadow that had remained in human form began to flow like a puddle of liquid, and finally became extremely deep, as silent as a pool of stagnant water.

In the shadows,

A blade floated up, hovering above the shadow, just where Cao Qin's hand could reach, and the knife body was wrapped with a layer of black shadow, the shadow flowed on the knife body like a liquid, without any cold light, from a distance, Cao Qin's hand was more like a flat burning stick.

With Cao Qin as the center,

The spiritual power surged like a tide, and the shadows under his feet also took on the shape of ripples.

Although the knife was tightly wrapped in shadows, Jiang Dong could still recognize it, this knife was actually the most common standard long knife in the school, and in the research institute of Dekar College, this kind of knife was often mass-produced.

Unexpectedly, there are really people using it.
