Gu Liang opened his notebook to a new page, and roughly drew the floor plan of Miracle High School.
Although it is said that cards have maps, drawing the map yourself is more conducive to thinking about the action line of the real murderer while drawing the map.
The teaching building is basically located in the middle of the whole school. The teaching building goes all the way to the south, which is the main entrance of the school, to the north is the playground, and further north is the canteen.
To the east of the teaching building is the library.
About 10 minutes' walk northwest from the teaching building is the dormitory area.
There are two buildings in the dormitory area, the teacher's dormitory and the student dormitory are located on the south and north sides respectively.
The flower bed where the first case occurred was 1,000 meters east of the dormitory.
From the teaching building, you can go directly to the dormitory in a straight line in the northwest direction, and it only takes 10 minutes; in addition, you can also bypass the flower bed and return to the dormitory through the flower bed.
There are cloisters around the flower bed, as well as rockeries under construction. It is a small garden for students to rest.
The student dormitory faces south. Boys live in 101 and 102 on the west side; girls live in 103 and 104 on the east side. Next to 104 are the rooms of Ma Qingjie and Aunt Guan respectively.
Room 101 and Room 103 are separated by the dormitory management hall, and Aunt Guan usually works at the registration office in the hall.
In other words, the five rows of rooms are actually side by side, and their doors are facing the corridor, that is, the direction to the south.
And their windows are facing north.
Through the window, you can barely see the direction of the cafeteria, but you can't see the flower bed.
July 24 was the time when the first incident occurred.
The murderous intent of the real murderer should have happened when the results of the mock exam were announced this morning.
At the swearing-in meeting, other people were listening carefully to the speeches of the principal and director, but the real murderer thought of what he knew about the serial murder case last year, and planned a murder plan.
He thought of the scattered bricks in the flower bed, so he had his first plan.
Since there was no small note similar to "See you at the flower bed at noon today", I can only think that the real culprit made a verbal agreement with Zhao Mathematics directly when others were not paying attention.
Classes ended at 11:30, and after lunch, the last Gu deputy class did not return to the dormitory, but returned to the teaching building to study.
The rest went back to the dormitory.
After a short rest, Zhao Mathematics went to the flower bed for an appointment. When he was in the dormitory hall at 12:15, he ran into Li Yingwen. Li English is going to the library now.
In the eyes of the dormitory auntie, only Li Yingwen and Zhao Xuexue had been seen going out. As for the other students, except for the deputy class Gu who had never been back, everyone had gone back to the dormitory and never came out again.
The four rooms where students live, the two rooms where employees live, and the dormitory hall are all side by side. From west to east are 102, 101, the hall, 103, 104, Ma Qingjie and Guan Aunt's room. However, there are no windows on the north side of the hall.
Gu Liang and the deceased Zhao Mathematics lived in 102 on the westernmost side of the dormitory.
Next to 101 lived Qian Huahua and the second deceased, Gu Fuban.
103 are Meng Yuwen and Li Yingying, one has been regarded as the real murderer, and the other is about to be regarded as the real murderer.
104 are two girls, Zhu Physic and Wu Bisheng, who haven't gone out for a whole noon.
The real culprit could only be to climb out of the north-facing window of the dormitory to the outside of the dormitory, walk through the windows of each dormitory with a cat, and go all the way to the east. Get out and continue east toward the flower bed.
Ma Qingjie and other employees will eat after the teachers and students have finished eating; except for Aunt Guan, she either rushes to the cafeteria early to eat, or Ma Qingjie brings one back for her, because she has to stay in the dormitory hall all the time to control the students. In and out of the situation.
These things, the students are clear.
Therefore, the real murderer knew that Ma Qingjie hadn't come back at that time, so he dared to steal the rope through the window.
In this way, the real murderer can climb the window, steal the rope, and reach the flower bed without attracting anyone's attention.
At this point, Gu Liang made another confirmation. There is no problem with the real murderer in the first case.
But the second case is a bit more difficult to say.
If hypnosis, key theft, murder, etc. all happened in less than 35 minutes, if the murderer really walked out of the classroom, no matter where he went to get the murder weapon, it felt very unlikely.
In the blink of an eye, Gu Liang thought of something, raised his head, and said to Li Xiaoyu, "Open flames are strictly prohibited in the dormitory, and knives are also strictly prohibited. I remember that we searched for evidence yesterday, and we did not find any knives. Only the rooms of Aunt Guan and Cleaning Ma have them." Knife."
"I would like to trouble you to confirm the possible location of other knives by searching for evidence or checking with other players. We did not search the teacher's dormitory carefully yesterday. I would like to trouble you to confirm whether there are knives over there."
"Okay." Li Xiaoyu nodded, "Is there anything else you want to tell me?"
Gu Liangdao: "Check the rooms of each suspect, especially Zhu Physics and Qian Chemistry. Let's see who among them may have a variety of skills."
"Yang Ye and I went to the playground and the teaching building to take another look."
Li Xiaoyu agreed to come down and left quickly.
Yang Ye and Gu Liang went all the way to the teaching building in the southeast direction, then bypassed the teaching building and went north to the playground.
The place Gu Liang walked to was the place where they picked up the bloody cleaning cloth.
At that moment, Gu Liang stopped here, put his hands in the pockets on both sides of the school uniform, raised his jaw, and looked in the direction of the teaching building. To be precise, he was looking at the window of classroom 101.
Yang Ye walked to his side, and said softly, "Just now, I was thinking about the first question you asked—why the second one killed the last deputy Gu. I have some ideas."
Gu Liang nodded: "Yeah. Tell me what you think first."
Yang Yedao: "First, Deputy Gu did not return to the dormitory at noon yesterday; second, his handwriting on the test paper can basically prove that he was doing questions at noon. Through two factors, we basically ruled out the murder of Zhao Mathematics." Suspected. This matter has also been unanimously approved by everyone."
"Therefore, Gu Fuban is the least suspect in the serial murder case."
Hearing this, Gu Liang thought for a moment, then said, "Well, indeed. I understand what you think."
"The real murderer knows that he can hypnotize, so he can put the blame on Li Yingying, who also can hypnotize; as for Wu Shengsheng, we temporarily exclude Wu Shengsheng from her speech. Eliminating Gu Fuban is so powerful. Therefore, Wu Shengsheng is also suspected and can be blamed."
"Of the rest, Meng Yuwen was imprisoned; then I, Qian Huahua, and Zhu Physics remained."
"You excluded me before because of Gu's speech. From the analysis of scores and rankings, it is less likely that I will kill Zhao Mathematics first, but in fact, my suspicion cannot be completely ruled out."
"The suspicion of Zhu Physics and Qian Chemistry is even greater."
"So... the reason why the murderer killed Gu Fuban was because he was the least suspect and could not be used by the murderer."
Yang Ye said solemnly: "Yes, that's exactly what I want to say. This is a serial murder case. The murderer wants to ensure that he kills as many people as possible and enters the top three in the Olympiad. In order to achieve his goal, the murderer has a prerequisite , is to ensure that he will not be caught, that is to say, he must try his best to put the blame on others."
"Except for Gu Fuban, everyone else has the possibility of being blamed. When everyone thinks about logic later, they will rule out Gu Fuban. With one less candidate suspect, the possibility of finding out the real culprit is even greater. This is actually not good for the murderer. Therefore, the real murderer directly killed Gu Fuban who was useless to him."
Gu Liang half-closed his eyes, stared in the direction of classroom 101, and said again: "Yes. Your analysis actually confirmed my guess just now from a certain angle."
"In this serial murder case, the murderer has two main goals. First, to ensure that he enters the top three in the Olympiad; second, to ensure that he is not caught. When deciding the order of killing, he will consider rankings and scores But the priority of the second goal is actually higher than the first. After all, if he is caught, he will be completely finished, let alone the top three in the game."
"This inference, in fact, can be mutually verified with the real murderer's choice of the second killing of the ancient deputy class."
"Although Gu Fuban took the last place in the test, his score is not low. There are too many real murderers, and there is a possibility of catching up. So, maybe the murderer didn't list him as the priority to kill at first, but the murderer didn't think that, Killing him was unnecessary."
"Therefore, there was an error in our previous reasoning."
"It is no longer the ranking and the score that really determine the murderer's killing order. In fact, he only needs to kill 5 people, and if only 3 people remain, no matter what, he will surely be able to enter the top three."
"So-"
Gu Liang faced Yang Ye and said, "What really determines the order of his killing is his self-protection method. He has to think about how he can kill 5 people in a row without being caught. So, 'blame' , is the real key word in this serial murder case."
Yang Yedao: "Yes. That's exactly what I want to say. So your question is good. Why the murderer chose to kill the last deputy Gu is a very critical question. After clarifying this question, We now understand the murderer's real logic, which is very beneficial to our overall reasoning."
"So, what's your idea of coming to the playground?"
Gu Liangdao: "The key word in my brain is 'blame'. That's why I said, your analysis just now helped me to confirm my guess one step further."
Pausing for a moment, Gu Liang turned his head to look in the direction of classroom 101, and said, "Ma Qingjie went to bed at 7:50, and Gao Cafeteria at 7:55. This means that although the real murderer has mastered the method of deep hypnosis, every time Individuals actually have individual differences, so the real culprit cannot actually guarantee that everyone can fall asleep on time, and he may have an error of about 5 minutes or even 10 minutes."
"I recalled it carefully. After changing shifts at 4 o'clock, I didn't fall asleep on time, but it took about 10 minutes before I really fell asleep."
"Furthermore, in addition to the clock in the classroom, there is also time on the card. After I found the body, I checked the time on the card, and the difference from the clock is not too big."
"So, the real culprit adjusted the frequency of the hands of the clock at a certain point of time to urge everyone to sleep, but the frequency may sometimes be fast and sometimes slow, but in the end it didn't really change the time. This can actually be seen as the system helping us reduce the difficulty .”
"To sum up, it is temporarily assumed that the time of the clocks and watches that everyone saw last night is basically correct, at least the error will not be too large. Then the time for the real murderer to commit the crime is still less than 35 minutes."
"And considering that there are differences in the time when different individuals fall asleep under the influence of hypnosis, the overall crime time set by the real murderer at the beginning may be only 30 minutes."
"In addition, in Li Xiaoyu's hypnosis book, there is such a saying that ordinary hypnotists need to perform shallow hypnotism on the hypnotized person first, and then it is easy to successfully hypnotize the hypnotized person at a deep level after at least 3 times; Only a qualified hypnotist can jump over the shallow level of hypnosis and directly hypnotize the person being hypnotized."
"Combined with our inference that the real murderer must have performed hypnosis many times, this sentence implies two meanings. First, the real murderer is not a senior hypnotist; After the first hypnosis, the fourth deep hypnosis is only easier to succeed, but there is still a possibility of failure."
"Therefore, no matter from the fact that the entire crime process should only take 30 minutes; or from the fact that the real murderer cannot guarantee the complete success of deep hypnosis, he will not leave the classroom for too long, and he has to keep an eye on everyone at all times."
"So, my imagination is that although the real culprit stole the key, he never left the classroom at all."
Gu Liang took his hand out of his school uniform pocket, pointed to the direction of the classroom window, and said, "After we have this idea, we have to ask one thing, since there is no need to leave the classroom, why did the murderer steal the key?" ?”
"The bloody cleaning cloth is very large, covered with blood, and some of the blood is sprayed. It can be deduced that the real murderer is holding the cloth as a cover to prevent the blood from splashing on himself when killing people. Of course, later use The cloth used to wipe the keys and the blood on the murder weapon should also be this cloth."
"This brainstorm determines that the murder weapon must be in the classroom. And if the murder weapon is in the classroom, the real murderer just throws the bloody cleaning cloth into the classroom. Anyway, everyone is in the classroom. But why did he put Throw the cleaning cloth out the window?"
"It now appears that there is only one reason for the real culprit to do this—to mislead us."
"The real culprit should also be worried. Maybe just relying on a hypnotic brain hole, everyone can't directly lock the real culprit on Li Yingwen. After all, the first day they locked Meng Yuwen by throwing a shot put, but the answer was wrong; You can think in your mind that the next day, you shouldn't be able to lock on Li Yingwen just by hypnosis."
"So, the real culprit has set up a more complicated bureau."
Yang Ye nodded, the more he looked at Gu Liang, the more he admired him.
Every time Gu Liang reasoned, in Yang Ye's eyes, his whole body seemed to be shining.
Gu Liang looked back at Yang Ye, and Yang Ye took his words and said, "When we had a concentrated discussion in the morning, Wu Shengsheng brought up an idea. If the real murderer doesn't have enough time to get the murder weapon by himself, then he has an accomplice. Someone stole the murder weapon." I got the key and released Meng Yuwen from 201 on the second floor to kill people."
"Yes." Gu Liang said, "It's best to push the real culprit to Meng Yuwen. Because of Zhao Xuexue's death, she was already the biggest suspect. Now she may be released, so the second case, She certainly could still be one of the killers."
"No one said that there is no joint crime this time. If eight students want to compete, maybe two or even three will join forces to kill the other five?"
"So, the real culprit stole the key, just to set the blame. He never left the classroom at all. He just took the key to open the window and threw the bloody cleaning cloth on the playground. That's all."
"He stole the keys and threw the bloody cloth in order to mislead us—to make us think that the murderer had left the school building to go to the cafeteria kitchen north of the playground to get a knife."
"It takes at least an hour to go back and forth from the teaching building to the cafeteria twice, so the murderer must have an accomplice outside classroom 101. If we think this way, Meng Yuwen, who was locked up in room 201, was shot again."
"Then now—" Yang Ye stepped forward and held Gu Liang's hand, "Let's go, let's go to the classroom together to see... What is that thing that I missed that could be used as a murder weapon?"
