"The independent variable can be understood as the factor or condition that causes the change of the dependent variable, that is, the manipulated person, by the researcher's active manipulation. In short, it's the difference between controlling and being controlled. Wen Yifan wrote slowly, this time the notebook had a cover made of black leather, and the words "NOTE-BOOK" were printed with gold and flowers.

"It has been recorded that when this relationship is applied to human beings, it will produce inferior emotions such as superiority, which will make the relationship between the independent variable and the dependent variable no longer as precise and rational as the formula, so that there may be a mutual conversion between self-change and cause-change, and even a tight chain composed of the combination of multiple self-change and cause change such as z=y=x," Wen Yifan continued, "This layer of chain contains too many unstable factors, and wants to destroy it. The easiest way is to trace it back to the source step by step, control it, and make the independent variable of the source its own dependent variable, so that it becomes a new factor to join the chain, and then destroy it from within. ”

"This chain is the important chain that makes up the relationship between people." After writing this last sentence, Wen Yifan looked at these words that recorded the whole thing, and showed a satisfied smile. He flipped a few pages forward, wrote the words "Control" in standard block letters at the beginning, placed it in a bookshelf, wrapped it in another cover cut from another book, and after making sure that there were no inconsistencies, he turned on his computer and began to revise the title of his next assignment.

"I wonder what kind of problem it would be to put this chain of relationships of multiple variables into the students' exercises?" Wen Yifan smiled softly.

The known variables x, y, z, have the following relationship: A1z+B1=A2y+B2=A3x+B3, and the three constitute a chain.

Add a fourth element (format: A4k+B4, k is a variable, A4 and B4 can be any real numbers) to make it a new relationship chain, and write the values of A1, A2, A3, B1, B2, B3 according to A4k+B4, complete the chain, and find the values of x, y, z when k = 7 (A1, A2, A3, A4, B1, B2, B3, B4 are all coefficients, and A1≠A2≠ A3, B1≠B2≠B3)

Title: Control

Closing the notebook, Wen Yifan got up and walked to the fireplace.

Opening the door of the dark room, Wen Yifan slowly walked down the stairs and looked at everything around him.

The plastic wrap on the floor was long gone, the floor and the dissection table were bright in the light of the fire, as if they had been carefully wiped, and there were several packages in the corners, all of which were firmly held by the plastic wrap.

After taking a deep breath and making sure that there was no peculiar smell, he picked up one of the packages and slowly untied the plastic wrap, so that the slices of meat boiled in boiling water would not ooze blood, which was common sense in cooking.

Picking up the backpack, the effect of activated charcoal is good, and there is no smell coming out.

Throwing his backpack into the car, Wen Yifan, who was dressed in casual clothes, got into the car, not worrying about anything being found out. Even if they inspect the car, all they can find is a bag full of cooked meat slices and labeled "pork".

However, before placing it in a scenic area, he suddenly wanted to meet an entrepreneur.

………………

"What do you think about the disappearance of the client, Miss Luo Wenying?"

As soon as he arrived at the place, Wen Yifan heard such a conversation, and it was obvious that he happened to run into an interview.

"I don't want to make any response," the middle-aged man looked calm, "Luo Wenying's life and death have nothing to do with me, on the contrary, my daughter is dead, and you are insulting my daughter on the Internet without any direct evidence of school violence, what I really care about is this." ”

"Then do you hate Luo Wenying?" The reporter was clearly not satisfied with this answer.

"Hate or not, it doesn't have any effect," the middle-aged man just glanced at the reporter coldly, "I don't know about her disappearance, but even if she is really killed, I will not give any sympathy, this is a father's anger at his daughter's slander." ”

Hearing this, Wen Yifan smiled slightly, and then left here.

Very good, almost perfect answer, almost perfect independent variable.

"It's cold-blooded! It's obviously his daughter's fault, and he wants to be angry with the victim! ”

"Yes, there are people who believe their nonsense! If you want me to say, this kind of entrepreneur is rich in the second generation, and there is no good thing! Every day I know that if you bully our people, you should be killed one by one! ”

"Really, Luo Wenying is obviously such a hard-working and simple girl, and she forced him to say that she is a scheming conspirator, if you want to talk about conspiracy, the poor people in the countryside are really not as good as these Sven scum!"

"If you want me to see it, it's probably the hand of this beast, these rich people, they're very perverted!"

Looking at the report about this interview, Wen Yifan smiled helplessly.

Look, it's all dependent variable~

………………

"You say, why did Luo Wenying disappear?" Liu Wenyu yawned and couldn't help asking.

"Who knows, there are so many police forces, and they haven't been found yet." The answer was a female police officer, "Eh, by the way, Xiao Liu, is the tall man you said handsome?" ”

"Handsome, handsome!" Liu Wenyu smiled, "Teacher Wen was fascinated by ...... at the beginning."

When he said this, he regretted it.

"Oh~ It turned out to be Mr. Wen who came to you that day!" The female police officer smirked, "Do you have a photo?" Let me see what it looks like? ”

"Shhh......h

As he spoke, Liu Wenyu's voice suddenly became smaller, and he remembered embarrassedly that he had known Wen Yifan for so long, and he really didn't have a photo.

"It can't be true," the female police officer was dumbfounded, "I heard that Mr. Wen is very handsome, if you get me a photo, I'll treat you to dinner!" ”

"One...... Deal! Liu Wenyu hurriedly nodded, and then asked with a wicked smile: "What if you can let him meet you directly?" ”

"Two meals, then! Please let me know in advance that I will be dressed up. The female officer grinned and held out two fingers.

"Wrap it up on me!" Liu Wenyu snapped his fingers, "However, the most difficult thing to handle is this kind of disappearance case." ”

"Yes, there are so many disappearances in the files, and I don't know when they will be solved." The female police officer echoed.

"Don't you suspect that a criminal gang sells organs!" Liu Wenyu shook his head and called up a picture, "The only sighting photo is still blurry, I can only vaguely distinguish that it is a man in black, and at that time he also said that he likes to wear black clothes, and a man who is thin and tall is more than 1.75 meters tall, it is really too hasty, according to this feature, I will check the locations of various missing cases one by one, it is estimated that we will not be able to finish the investigation, not to mention anything else, Mr. Wen likes to wear black clothes, and his figure is more than 1.8 meters tall, you say he is suspicious?" , it's not. ”

"That's it," the female police officer stretched out her head and glanced at it, it was roughly the back of a man with a satchel walking on the barren mountains and mountains at night, and the photos taken were very blurry even if they used high technology, "The range is too big!" ”

"Alas, I'm so tired, it's not time to get off work yet." Liu Wenyu yawned again, saved the picture easily, and stopped paying attention to these recorded disappearances.

If Wen Yifan saw this picture, he might recognize that this was his package at the end of a certain time......

………………

"And then?" Officer He stopped his pen and asked.

"Later?" Wen Yifan sat up straight, "I kept the agreement and let her go to many places. ”

"Those are the locations, please point them out." Officer Ho pulled out a map.

"Give up, it may be long gone, for wild animals, buried meat can't escape their sense of smell," Wen Yifan said this, but still circled a few locations on the map, "As you can see, my memory has always been good." ”

"Didn't you think about revealing the truth?" Officer He asked.

"The truth? Who cares? Wen Yifan smiled, "If you put a truth in front of you that is completely different or even contrary to most people's intentions, do you think they are willing to believe it?" ”

"There will always be sane people." Officer Ho fastened the cap of his pen.

"I'm also selfish and think that only certain people are qualified to listen to good stories." Wen Yifan shrugged his shoulders, "It's a pity that there are not many people in the public who are worthy of listening to my story." ”

"You mean, I'm worthy?" Officer He smiled.

"Of course you deserve it, officer," Wen Yifan also smiled, "As the only police officer who has seen through all my disguises and brought me to justice, if you are not worthy, then I am afraid there is no one worthy of it in this world." ”

"One thing I'm curious about," Officer He asked, "how did you know everything about Luo Wenying?" ”

"It's not difficult to explain," Wen Yifan raised his eyebrows, "The initial suspicion came from all kinds of coincidences and discords from the incident, such as the diary found by Luo Yanhong, such as Luo Wenying, who was still calm at the scene of the murder, and the evaluation of Gao Wenqing by his classmates, all of which were positive. ”

"What's more, putting aside the phenomenon and looking at the essence, the biggest beneficiary of this incident is also Luo Wenying, which makes me sure that there must be some hidden secrets."

"Just because of suspicion, I went to kidnap Luo Wenying, what a boldness." Officer Ho chuckled.

"Not only that, but I also hypnotized her." Wen Yifan smiled rather than smiled, "After hypnosis, I determined that she was transformed from a slightly deformed inferiority complex to an extremely narcissistic personality, this kind of personality will definitely not swallow bullying as she said, and will definitely make an extremely strong counterattack, and the rest, combined with her psychological degree, is easy to guess." ”

"I almost forgot, you're also a psychology professor." Officer Ho recorded his words, "Is there anything else you would like to add?" ”

"It's gone." Wen Yifan spread his hands.

"Ten minutes off, I'll pour you a glass of water, and you think about what to say next." Officer He got up, picked up the materials and walked out the door, "I'll check your notes." ”

"Please." Wen Yifan nodded, and then fell into silence......
