"Malevolence in human nature: greed, jealousy, is really a terrible negative energy, which makes people chill ......"

"Malicious...... Is it? Gently closing the book and returning it to the shelf, Wen Yifan got up and looked out the window.

It's still early and the sun is shining.

"If malice is controlled a little...... No, it's a little bit of control over the malice of others, what happens? ”

The bright sunlight shines on the people who are falling into reflection by the window, like angels who shed kindness on the earth.

The light does not know people's hearts, and it has never set foot here.

Wen Yifan looked at the bright sunshine, just smiled quietly, a familiar bell came from outside the door, and he began to skillfully clean up last night's lesson plan, his movements were not a little hurried, but he did not delay for half a minute.

At 9:40, the class bell rang on time, and he walked into the classroom and began the lesson.

"Teacher Wen is still like a monster, every time he just steps on the class bell and walks into the classroom."

"Yes, yes, I don't know if Teacher Wen is cooperating with the class bell, or if the class bell is cooperating with Teacher Wen."

"Stop talking, I still have to listen to the class!"

"Cut~ Isn't it because Mr. Wen is handsome? If it were a middle-aged bald uncle, you would have escaped long ago...... Oops, it hurts, I'm wrong big sister! ”

"Pap-papa-papa" Wen Yifan's fingers gently tapped the blackboard three times, and the commotion in the audience suddenly quieted down.

"Ladies and gentlemen, the topic of today's lesson is functions," Wen Yifan leaned over, put his hands on the podium, and supported his upper body, "but the ancients learned from the past, so let's start with the basic definition of functions - dependent variables and independent variables. ”

After straightening his collar, he continued: "So, can any of you tell me about the definition of dependent and independent variables?" ”

"An independent variable is a variable that causes a change in other variables, and a dependent variable is a quantity that is affected by a change in some variables." A voice came, Wen Yifan followed the voice and looked, and the female classmate who answered was in the second row.

"Ning Yufang, the upper level of school grades, is 1.53 meters tall, weighs 67 pounds, and is malnourished." The student's information in his mind instantly appeared, and Wen Yifan smiled at him in return, "That's a good answer." ”

Being praised by Wen Yifan, Ning Yufang's face was full of happiness, and she couldn't help but cover her face and snicker, this action was instantly extremely despised by her fellow table......

"Everyone should be familiar with independent variables and dependent variables, but when I was studying psychology, I also studied them for a period of time," Wen Yifan said as he wrote down the relationship of "y=x" with his right hand, "In our psychology, independent variables can be understood as the factors or conditions that cause the dependent variable to change due to the researcher's active manipulation. In short, it's the difference between controlling and being controlled. ”

"Is the teacher a dependent variable or an independent variable?"

"I don't belong to any of them." Wen Yifan smiled when he heard it, he saw that the students were puzzled, so he explained: "Our life is not as accurate as mathematics, there is no truth or falsehood, so sometimes we may be the independent variable that controls others, sometimes it is just the opposite, and even sometimes we ourselves can't tell which of the two is in between, so it is a very irrational decision to look at life from a mathematical point of view." ”

"However, I still hope that everyone can be the independent variable in life," Wen Yifan laughed, "to control everything about themselves and even others, rather than being passively controlled by others." ”

"Wow - Mr. Wen is easy to attack!"

"Well, but it looks like a gentle little suffer! Is this the contrast cute? Loved, loved! ”

There was another burst of discussion, Wen Yifan didn't stop it too much, but chose to continue the course.

He didn't expect students to fully understand what he was saying.

When they fully understood, they became monsters themselves.

………………

A month ago......

"This homeless man is not a thing!"

"I heard that although that female college student is a rich girl, she usually doesn't have any arguments for people! They even raise money in their own name! ”

"yes, yes, I've heard that it's disgusting to be able to kill someone who kills this kind of schoolgirl!"

"10,000 Blood Letters for the Death Penalty (1/10,000)"

"Shoot him quickly! This kind of scum doesn't deserve to live in the world! ”

…………

Looking at the news about the rape and murder case on the Internet, Wen Yifan just read the text quietly, with a slight contemptuous smile on the corner of his mouth.

"Malicious...... Is it? Touching these two words again, he suddenly became interested.

"Please calm down, maybe things are not what we see, think about it, there are a lot of doubts in this."

After typing this sentence, Wen Yifan sat in front of the computer, he wanted to see what would happen when the "justice" called "the public" added some remarks that did not match others?

"Who is this man? Standing and talking doesn't hurt your back! ”

"You understand again?"

"At first glance, he looks like a middle-aged uncle who is as disgusting and greasy as a rapist!"

"Gong Jing, the identification is complete."

Although he already knew the result, Wen Yifan still took a picture of these words with interest and saved them in the computer.

"The ...... independent variable and dependent variable" once again opened the lesson plan for the next class of students, and Wen Yifan gently drew a double horizontal line under these two words.

"There are no tight limits to the relationship between the manipulator and the manipulated, and even strangers have the ability to manipulate the emotions of others." Tearing off a sticky note and sticking it to the textbook, Wen Yifan wrote down such a sentence, and then closed the web page.

Manipulating other people's feelings can bring you pleasure, but it can only be considered a pastime, after all, it is too simple and can easily get out of control.

"It is said that people bring the malice in their lives to the Internet," Wen Yifan quietly looked at the sun and pondered, "Or are people just good at exporting everything they receive as malice?" ”

Opening the saved picture again, Wen Yifan smiled.

"If the truth is the former, I'm a little curious about the source of this malice, maybe one day, I can try to visit the person who outputs malice, maybe I can come across a good story!"

Opening the notebook, he took a pen dipped in ink, and lightly wrote a red full stop after a certain name on the notebook.

Cleaned up.

And above this name, there are countless names written in block letters, followed by a red period.

If someone from the adjudication court saw these names, they would definitely recognize a few of them.

Because they are all recorded in the file, Type: Missing.

Opening the mezzanine of the drawer, the fingers of his right hand tapped the tabletop, and his eyes couldn't help but sweep to a corner of the bookshelf.

The sun shines brightly, and there is a slight reflection there.

It's a sharp scalpel.

"Well, the plastic film doesn't seem to be enough, maybe it's time to go to the factory and get some." Wen Yifan opened the map, there were countless marks on it that others couldn't understand, and his fingers wandered on it, and finally stopped at a certain triangle.

"Then go to this one! The last time I bought plastic film at their house was five months ago, and I should have lost my impression of me, but to be on the safe side, let's dress up! ”

After changing into a pair of short-sleeved shirts and shorts, a pair of dark slippers, a fake mustache glued to his face, and finally a pair of sunglasses, and a little more detail, he walked to the mirror.

A person with the temperament of a middle-aged uncle appeared in front of him.

After watching it repeatedly, and making sure that even Liu Wenyu couldn't recognize him, Wen Yifan nodded with satisfaction.

He looks like a middle-aged uncle who lives near a store and just goes out to buy some things, dressed casually.

However, in fact, the shop was at least 20 kilometers away from the villa, and he needed to drive there.

………………

"Good afternoon." The sound retracted in the dark room, Wen Yifan was still holding a lantern in one hand and a carefully prepared meal in the other, and after walking below, he slowly put down the meal and placed the lantern next to the dissecting table.

But there was no one on it.

The sound of the wind came from the right, and Wen Yifan just turned to one side and dodged this attack.

"It's nice to think of sharpening your nails and cutting through the tape." There was still no waveless sound, and his left hand grabbed it according to Fang Cai's position, perfectly jamming the woman's neck.

"But it's a pity that I close the door every time I come down, and if you want to attack me, you must want to get the key!" Ignoring the woman's struggle, Wen Yifan hugged her to the dissecting table again and tied her up again. This time, a belt was used. "As you can see, I sometimes give people who come here some possibility of escape, such as the tape that ties you is one of them, and with these hopes, if they can break through them one by one, they will be able to get out of here, which may cause me a little bit of trouble, but it's funny, isn't it?"

Looking at the desperate eyes of the woman in front of him, Wen Yifan smiled.

"It's a pity that everyone only has one chance, it's a pity that you didn't grasp the opportunity I gave you," Wen Yifan smiled and picked up the pillow that the woman was on, "The pillow was carefully prepared for you by me, and it will bring you good luck." ”

The woman showed a suspicious expression, and Wen Yifan only smiled slightly when she saw it, and cut open the snow-white pillow.

Inside lay a key quietly.

Tears flowed and the woman shook her head as if she didn't want to believe it.

"Well, now it seems that you didn't take advantage of the opportunity," Wen Yifan put away the key and smiled slightly apologetically, "But it doesn't matter, no one before you has ever actually escaped from here, in a sense, you are already very good." ”

Seeing that his praise did not comfort the woman, Wen Yifan picked up the plate.

"So, you've lost your chance to escape from here, why don't you just give up and tell me a story?" Still scooping up a spoonful of food, "Or do you think you'll be able to find something that I haven't even noticed?" ”

"You...... You're a demon! The woman replied in a trembling voice.

"I never said I wasn't." Wen Yifan shook his head slightly, "However, if you and I are both abominable murderers, then what qualifications do we have to accuse each other?" Isn't it? Ms. Luo? ”

The light shone on the woman's frightened face, and if the police officers who had been involved in the investigation of the 7/11 rape and murder case in the first place, they would have recognized her.

The fire flickered, and the monster was whispering.
