Chapter 4 Chapter 3 Haircut

Teacher Zhou walked over with a frown, glanced at the ground, and suddenly asked: "You said it was dead, so where is the body?" Economist Becker once adopted the traditional economic concept of individual rationality, and briefly explained the so-called bad boy. Rational actors are assumed to maximize their utility function under the constraints of limited resources.But in Becker's analysis, both "utility function" and "effective resources" are given in unconventional senses. The utility of altruist b, who helps egoist i, is assumed to be a function not only of b's own consumption but also of i's consumption.

And, similarly, the finite resource of b, the "basic" budget constraint, is what Becker calls the social income.Social income consists not only of b's own income, but also of the value of i's income to b. Under this assumption, if b can transfer money to i without any loss of money, then when b transfers enough money to i such that a small change in b's own consumption has exactly the same marginal utility as a change in i's consumption , an equilibrium is reached. The theoretical result that Becker deduced from this analysis is the famous "bad boy theorem".

The theorem says that, in fact, the egoistic "bad kid" (i) may be induced by the altruism of the "big father" (b), as if i were also altruistic.Because in i's own (self-interested) interest, b is expected to tend to shift in such a way (given b's altruism) that b's situation is also improved. This not only increases b's "subjective utility", but also improves b's "objective" income through i's behavior. The bad boy theorem can be thought of as involving two related consequences.The first result relates to how well the bad kid (i) behaves in anticipation of the altruistic behavior of the father (b).The second result has to do with the "objective" benefits obtained by altruistic fathers.

Human beings always like to categorize everything.Even unmeasurable human behaviors are tried to be explained by mathematical formulas.It's really hard for me, who is also a human being, to understand. Introduce yourself as usual.My name is Yebuyu, I have a high IQ, but most of the time I am rational and boring. Since I was a child, many strange and inexplicable things have happened around me.Feeling this, I began to record them one by one with a pen, and wrote them into novels.Yes, this is the book you are holding. As I read the above data, I was drinking coffee and thinking about some messy things.The data was given to me by mail by the old man Yang Junfei, who also mailed me a bunch of inexplicable newspapers.

The news on these newspaper clippings all happened in various big cities in our country. If you have to sort out the same points, there are probably four: First, it was a murder case; second, the murderers were very young; third, they were all students with excellent academic performance; fourth, these children killed either their parents, teachers, or classmates, and almost all of them were familiar people.And all the methods are incredible and unheard of. Just after reading the information, the old woman Lin Zhiyan had already opened the door and walked in.For the rare occasion she didn't tease me, she just handed me a folder.

"It contains your new identity and this afternoon's air ticket. This time you are going back to your old job." "Old business?" I frowned. "Bad students, and they are heinous, the kind of social trash. How about you, you can restore your nature, happy?" This dead woman revealed her true nature not long after she was serious. "And I, playing your old sister, a poor persecuted person." She acted like a full victim, very pitiful. I kicked it with one kick: "Disgusting. What's wrong with this case? Where do you want to go undercover?"

"It is mentioned in the materials that it is a private school called 'Huayuan Bad Behavior Education Center'. We checked, and in all the murder cases published in the newspapers, the murderers only have two things in common: they were all bad students once, And they all had character correction at that school." I took out the data and looked at it. After thinking about it for a while, I felt something was wrong. "It is impossible for the local police to not notice such a simple connection? The police did not intervene in such a big case?" "I have to say that human thinking is very strange. Of course, the police had suspicions, but after investigating the school and randomly checking the mental state of several children, they ruled it out. It is said that the principal is also in the political arena. He is a very important person, and the police dare not offend too much."

Lin Zhiyan smiled and said, "It's been a long time since I've had a partner, sister, I'm so excited!" "I don't think it's been a long time since I traveled on public expense, so I'm just too suffocated." I packed my luggage while talking, and boarded the plane to the destination city with the old woman. I have to say that the old man Yang Junfei's identification was done very carefully, which allowed me to enter this school safely without arousing too much suspicion. But not long after entering the school, he saw a stinky kid who was alive and kicking with a face full of stinky farts died in front of his eyes, but he couldn't hide the complicated emotions in his heart.

coincide?How can there be such a coincidence?Just after I finished reading the school rules posted on the wall, the smelly smoking boy broke his neck and died in accordance with the punishment of the school rules. This is really chilling. The two children next to him, the girl fainted, Zhang Guofeng was a little bit better, but his whole body was trembling with fright, and he kept wiggling. I calmly walked to the door of the dormitory and shouted a few times before Teacher Zhou came over: "What's wrong?" "Someone died!" I hurriedly pulled his arm and said, "A ceiling fan blade just flew in and cut the neck of one of our boys, and the head fell off."

Teacher Zhou walked over with a frown, glanced at the ground, and suddenly asked: "You said it was dead, so where is the body?" "At..." I pointed to the position of the third bed from the left in the last row of the dormitory, and I was about to speak, but I suddenly closed my mouth again.The speed of closing his mouth almost bit off his tongue. Sure enough, the ground beside the bed was clean, how could there be the boy's body?No, not to mention the corpse, even the bright red blood that was sprayed everywhere is gone. "I obviously saw it just now." I said in panic, and pointed to the wall not far away: "I just read the school rules, and I heard a 'pop' sound..."

Before I finished speaking, I closed my mouth again.On the wall I was pointing at, the note with the school regulations also disappeared without a trace, as if it was just a psychedelic dream in spring, which had never appeared before. Seeing my dumbfounded expression, Mr. Zhou didn't have any expression on his face, as if his facial muscles had been petrified, he just said: "When freshmen enter school, they will have illusions because they don't adapt to the environment. Just get used to it. " He patted me on the shoulder and walked out of the dormitory door. As soon as he went out, the frightened expression on my face disappeared, and all that was left was confusion. what happened?Why, under the nose, not only the corpse and the bloodstains disappeared, but even the school rules disappeared?Is it really an illusion? Turning my head to look at the girl who fainted on the ground, and Zhang Guofeng, who was trembling with fright and hadn't calmed down yet, I snorted coldly.It's definitely not an illusion, there must be something that I have overlooked! This school seems to be more troublesome than I imagined. I walked to the place where the body disappeared and looked it over carefully, then tapped the ground with my hand. The sound is very solid, there is no hollow feeling, it is solid concrete.Sure enough, there was no trace of blood on the bedding and blankets, and the magic-like disappearing technique made me, who understands the principles of magic, have no clue at all. But one thing is certain. The school rules mentioned by the principal, dean of students, and Teacher Zhou do exist and cannot be violated.Otherwise, you will be punished as stated in the school regulations. Humans are strange creatures.Old people often warn you not to be overconfident. Many times when you think you can control it, you are already deeply involved. Take drugs for example. When many people first try drugs, they are just curious and feel that they will not be addicted. I sat silently by the bed, waiting for Zhang Guofeng and the girl lying on the ground to wake up. Zhang Guofeng is worthy of being a gangster. He hugged the foot of the bed, supported his body tremblingly, and asked stammeringly, "What's going on? Dead, is he really dead?" "I don't know, maybe we have a collective hallucination." My smile was a bit bitter. "Collective what?" He couldn't understand the word. "It's just that the three of us saw the same hallucination. At a certain time, there were real cases." I explained. "Impossible, how can there be such a real illusion!" Zhang Guofeng shook his head without hesitation. "Okay then, go look for his body, even if you find even a little bit of blood, it will prove that what we saw is not a hallucination." In front of the girl, among those who pinched her hard. The girl finally woke up with a "woo". As soon as she woke up, the first thing she did was to hold me tightly and cry loudly. While crying, she timidly asked, "He's dead! He's dead!" Is there any mistake, why one and two have this kind of reaction.I was so annoying that I couldn't take it anymore, I slashed her neck with a hand knife, and made her faint again. The world is finally clean. Zhang Guofeng stared dumbfounded at my flowing movements, I shrugged my shoulders, "This woman is too noisy." After speaking, I looked around on my own. Due to the suddenness of the incident just now, I really hadn't observed the surrounding environment, so I found out what kind of place the dormitory I'm going to live in is like. This so-called dormitory is very large, about 70 square meters, and the concrete floor has many neatly arranged small holes.In my impression, only the chemistry classroom will punch holes in the ground to connect to the water pipes and power lines because of the frequent experiments.It seems that this was once a chemistry classroom! The dormitory is densely packed with forty-nine beds, seven horizontally and seven vertically, exactly a square shape. There are personal belongings on the six rows of beds in front, which belong to the occupants.Only the last seventh row is still completely empty. In the beds of those who live there, the personal belongings include women's underwear and men's clothing. When Teacher Zhou asked that girl to sleep next to me just now, I thought it was just a kind of stalking.Unexpectedly, this school is really mixed with men and women living together, it is incredible. Isn't this afraid of some serious problems between men and women? After thinking about it, I shook my head with a wry smile.Just now a person died in front of me, since people can die at will, what is there to be afraid of? There are old calendars pasted on the windows of the dormitory, and it is impossible to see the scene outside the window at all. I went to the window and wanted to push it open, but no matter how I pushed it, the window didn't move.I tapped lightly on the surface of the window, but I didn't hear the crisp sound of the glass, but the muffled sound of "bang bang", as if it was nailed to death with a wooden board. What is this school trying to do?Not to mention the inexplicable school rules and co-ed dorms, even the windows were nailed down to prevent people inside from looking out, and there were not so many messy places. I kept the scene in the room firmly in my mind, and walked slowly towards the door of the dormitory. Just as I was about to open the door and go out, I suddenly saw a note pasted on the back of the door. The so-called school rules. Article 92 of the school regulations: Freshmen are not allowed to leave the dormitory without notice, and those who violate it will lose their hair. The hand that was stretched out to push the door was retracted immediately, I lowered my head and thought about it, and when I raised my head, I had already piled up a smile on my face: "Little brother Guofeng." "Yes!" The little bastard probably got used to it, and immediately responded loudly on conditioned reflex. "It looks like someone is calling you outside." I lied kindly. He listened carefully: "No?" "Obviously." I pressed my ear to the door, "It's a man's voice, could it be that your father is reluctant to part with you and came back to pick you up?" "Really?" He was probably so frightened that he really didn't want to stay in this ghostly place anymore, and didn't think about the truth, so he pushed the door open and ran out, shouting in a rough voice: " old man?" The door of the dormitory was opened wide, and a bone-piercing cool wind rushed towards him. I shuddered.I saw a corridor outside, a snow-white corridor, and thick limestone was smeared on all four sides of the walls.The description is correct, it is indeed four sides, even the ground is no exception. There were also no windows in the corridor, and the glaring white made people feel depressing, as if they had entered a lunatic asylum.Strange, when I came just now, I obviously came in through this door. Although most of my attention was on observing the teacher surnamed Zhou at that time, I also paid a little attention to the environment. It wasn't this way at all. When I came here, the road was still normal, there were windows to see the outside, and the floor was patterned floor tiles. I recalled it carefully, just now when the person died, I opened the door of the dormitory to call for someone, but the corridor was vaguely normal.But why has everything changed in only ten minutes? Zhang Guofeng stood blankly in the snow-white corridor, obviously confused because he didn't see his father. Just when I was wondering why the punishment of the school rules hadn’t appeared yet, suddenly, something fell from the ceiling at lightning speed. With a sound, it shattered into countless pieces and sprinkled on the ground. Zhang Guofeng was taken aback, and ran back to the dormitory, only to look over in disbelief.I also saw clearly what was underground. It turned out to be a mirror, an extremely sharp mirror.Not far from the shards of the mirror, there was a dark mass.Upon closer inspection, it turned out to be hair. Where did the hair come from?I frowned and looked at the back of Zhang Guofeng's head, only to see that the crooked crew cut he cut himself in the teaching office looked very weird, and there was a bald patch on his scalp, and he couldn't see a single hair. It seems that what fell on the ground was not Zhang Guofeng's hair, who else?Fortunately, the mirror that fell suddenly happened to be behind Zhang Guofeng's head. Judging from the situation, if it was more than one centimeter, he would definitely die. Zhang Guofeng obviously understood this too, touching the back of his bald head, he was so frightened that he almost lost control of his bladder and bowels. Could it be another coincidence?Impossible, how can there be so many coincidences. I carefully looked at the place where the mirror fell.The walls are clean, whitewashed with plaster, and there is no trace of a mirror at all.It stands to reason that if there is really a mirror attached to that place, it should be cleaner than the surrounding walls, and it can be seen at a glance.But, I really can't find any strange marks in that place. With a slight movement in my heart, I suddenly remembered the situation when I saw the first school rules.I hastily opened the door of the dormitory and looked at the place where the school rules were originally posted. Sure enough, the place where the so-called "Article 92 School Regulations" was originally written was empty and there was nothing left. Twenty-seven seconds, this is the time I recorded from violating the school rules to the appearance of retribution.Although when he died not long ago, his memory was blurred due to panic, but now that he recalls carefully, the time is probably basically the same. It proves once again that the horrific punishment for violating the mysterious school rules is indeed groundless.Could it be that the school itself is a big magic institution?But according to all the data collected before coming here, there has never been a report of death or missing persons in this school.But just now, obviously a person died in front of him. Although the circumstances before and after death were very strange, my intuition told me that it was absolutely impossible to be an illusion.That person is really dead!Taking ten thousand steps back, even if that person didn't die, where did he go? After witnessing two school punishments, I have a slightly vague idea of ​​the so-called weird school rules.There is also a little bottom in the bottom of my heart. It seems that there is another guess to be tested. I looked at the door of the dormitory, gritted my teeth and walked out.When I came to the snow-white corridor, I suddenly felt a weird feeling of incongruity, probably because of the irritability caused by the white surroundings. The only hue of white is extending in all directions. The corridor in front of me is very long, and the end can't be seen at a glance. And when I came, I obviously just entered an ordinary one-story house.The one-story house was only more than twenty meters long. Why is the universe inside so deep, it's like traveling to another world! I suppressed the surprise in my heart and counted the seconds bit by bit.Twenty-seven seconds passed quickly, and the retribution of the school rules did not arrive.A feeling of ecstasy immediately filled the whole brain. I laughed out loud and couldn't help but sat down on the ground. It turned out to be exactly the same as the previous guess.The retribution of the school rules is only once, of course, it does not rule out that there is only one time in a certain period of time.As long as the previous person has been punished, the mysterious school rules will disappear automatically, and the retribution will not come to the next offender. Zhang Guofeng didn't understand my hysterical smile very much, and asked cautiously: "Brother, don't you know how to show your head?" "You're so funny." I stood up and was about to tell him what I found, when I suddenly closed my mouth again. All I heard was a sudden broadcast sound from the ceiling in the corridor: "Attention, the three new students, please rush to classroom 302 for class within ten minutes." three?It seems that the school is clear about the Martian who died and disappeared in the dormitory.
