SCI Mystery Series

After coming out of the postgraduate dormitory, the two decided to go to the scene again, and walked towards the building of the Department of Psychology.

"Xiao Zhan!"

Hearing someone calling from behind, Zhan Zhao and Bai Yutang turned their heads at the same time.

I saw a middle-aged man in his 40s wearing a white robe and glasses.He ran a few steps to catch up.

"Doctor Xu?" Zhan Zhao recognized Xu Ting, the school doctor of C University.

Xu Ting ran up to him, looked up and down for a while at Bai Yutang beside Zhan Zhao, and said with a smile, "That's him?"

Zhan Zhao smiled awkwardly, he knew that Dr. Xu liked to spread rumors the most, but now, he really didn't have the mood to care about what was wrong.

Xu Ting also didn't notice any difference in the expression on Zhan Zhao's face, so he continued to smile and said, "Dr. Several doctors thought he was going to die."

"Is Professor Xu okay?!" Zhan Zhao asked eagerly.

"It's okay! I've recovered. I'm sweating all over. I've been working here for 20 years, and I've never seen the old man move so vigorously!"

Hearing this, Bai Yutang smiled and blinked at Zhan Zhao, meaning "The old man is not dead, it's his fate!"

Zhan Zhao gave him a hard look.

Xu Ting wanted to continue talking endlessly, but the two listened to them losing their patience. They reasoned that there was still something to be done, so Zhan Zhao and Bai Yutang turned around and left in a hurry.

In a blink of an eye, he walked to the building of the Department of Psychology.

Zhan Zhao raised his eyes to look at the roof, and saw that under the strong light, he could barely see the guardrail outside.

"Xiaobai, are you too outrageous? You can see clearly like this?"

Bai Yutang proudly said, "What is this? My young master's dynamic vision ranks first in the entire air combat team. Let alone the railings, we can clearly see the shells flying over!"

Zhan Zhao glanced at him, and saw that the white mouse was so proud that it even raised its tail.

Borrowing the binoculars held by a police officer, Zhan Zhao looked up carefully.

After a while, put down the binoculars, Zhan Zhao frowned, "Something's not right!"

"What's the matter? Did you find something?" Bai Yutang took the binoculars and looked at them too.

"Have you noticed that the direction of the guardrail is not right?" Zhan Zhao asked Bai Yutang.

Bai Yutang put away the binoculars and looked at Zhan Zhao: "You said so, indeed! If Li Feifan stumbled and fell because he was leaning on the damaged guardrail, then the guardrail should be turned outwards, even if Li Feifan fell before he fell. If it gets to the guardrail, it should be turned out first and then folded down! But here..."

"That's right!" Zhan Zhao said, "The guardrail here is almost vertically downward, and there is no tendency to turn outward!"

"Cat, I have an idea!" Bai Yutang said suddenly.

Zhan Zhao also said, "What a coincidence? I also have an idea!"

The two looked at each other with a smile, and then walked into the building.

This time, they didn't go to the rooftop, but to the floor below the rooftop, which is the top floor of the Department of Psychology building - the 13th floor.

The Department of Psychology Building of University C was just completed and put into use, so not all the floors have been renovated. The 12th and 13th floors on the top floor have been left unused, and some raw materials have been piled up, and even the doors have not been installed.

The two walked along the corridor and looked at each room. In front of the door of the fifth room, they saw the guardrail hanging upside down outside the window.

Zhan Zhao grabbed Bai Yutang who was about to go in, and pointed to the house number above the door frame——13——5

Bai Yutang asked in surprise, "135?"

Zhan Zhao nodded!Looks like I found the right place!

The two walked cautiously along the wall into the room, and saw that the floor was very messy and dusty, as if it had been scratched deliberately. Although there were no footprints, it was obvious that someone had been there.

When they walked to the window, they saw that the guardrail was less than one meter away from the window sill. Bai Yutang took off his windbreaker and handed it to Zhan Zhao, then turned around and walked out. Zhan Zhao grabbed him and said, "What are you doing? This is 13 Lou, this is no joke!"

Bai Yutang scratched his nose with a smile: "Stupid cat! How can I be afraid of heights!"

Zhan Zhao was a little embarrassed: "Should I call a few people over and take some safety measures..."

Bai Yutang smiled and unbuttoned his collar and cuffs, tapped Zhan Zhao's chin with his finger: "Don't worry!" After speaking, he quickly walked out the door and ran to the rooftop.Zhan Zhao only had time to shout: "Be careful!", the man had disappeared, and he could only wait anxiously at the window with his clothes.

After a while, Bai Yutang climbed the guardrail and got down to the window sill. Zhan Zhao was terrified and was about to pull him, when Bai Yutang yelled, "Cat, move aside."

Zhan Zhao subconsciously stepped back a few steps to the side, Bai Yutang swayed in the air a few times, jumped in neatly from the window sill, landed firmly on the ground, and patted the ashes on his hands.

Zhan Zhao was so angry: "Can't you stop thinking about being handsome??"

Bai Yutang shrugged: "I'm already handsome!"

"You..." Zhan Zhao, who was so angry that he couldn't answer, could only stare at him with puffed cheeks, he knew in his heart, "Bai Yutang used this dangerous method because he was afraid of destroying the clues that might be left on the window sill. Action. Although I know that he has always been desperate when handling cases, but seeing it with my own eyes is still so shocking that my heart almost jumped out."

Bai Yutang finished patting the ashes, and said: "In this way, the fact that the roof door is locked from the outside makes sense, but I still can't figure it out."

Putting on the windbreaker, he turned up his collar and said, "If the murderer pushed Li Feifan down first, and then climbed down the guardrail by himself, the time would be too short. It is impossible that there are no witnesses!"

Zhan Zhao nodded: "Indeed, we rushed out of the building the first time, and we didn't see anyone! Besides, it's too risky for everyone to watch. Unless..."

"Unless what?" Bai Yutang looked at Zhan Zhao in confusion.

Zhan Zhao looked at the guardrail outside the window: "Unless Li Feifan didn't fall from the roof."

Bai Yutang was taken aback for a moment, and then suddenly realized, "That's right! My door was misled by the guardrail! He was thrown out from here! The murderer may have made the guardrail like that last night in order to make Li Feifan The illusion of locking the door by yourself!"

Zhan Zhao nodded: "Most people wouldn't look up at the top! And even if they did, they wouldn't be able to see clearly!"

Bai Yutang looked around: "In other words, this is the scene of the first murder! But the murderer is really bold, he threw Li Feifan downstairs, and then came out from here, it is very likely that he will be discovered or arouse suspicion... ...and, why bother?"

Zhan Zhao pondered for a while, his face was a bit perplexed.

"Cat, what did you think of?" Seeing his expression, Bai Yutang knew that he must have discovered something.

"...If you think about it from the criminal's psychology, he must have a purpose in doing this, but, on the contrary, it's just trying to cover it up!"

"How to say?" Bai Yutang listened to Zhan Zhao's professional analysis with great interest.

"The murderer took great pains to cover up the crime scene! The purpose of forging the crime scene is nothing more than to create an alibi for himself!"

"Yes!" Bai Yutang nodded.

"The so-called alibi is actually to rule out the possibility that he was present at the crime scene at the time of the crime!" Zhan Zhao continued, "If the murderer's logic is used to divide the time of the crime into sections, then the whole incident can be divided into four parts. Duan! That is, 'Li Feifei entered the building, was killed by the murderer, fell down and was found, and the murderer left!'”

"That's right!" Bai Yutang rubbed his chin and listened carefully.

"The order of the first two paragraphs, that is, after entering the building and being killed, cannot be tampered with!" Zhan Zhao continued patiently, "However, the last two paragraphs, that is, falling from the building and the murderer leaving, can be tampered with. !"

When Zhan Zhao said this, he paused for a while to let Bai Yutang digest these words. With his extremely high comprehension ability, Bai Yutang immediately understood what Zhan Zhao meant: "I understand, that is to say, the murderer left the scene first, Li Feifan Falling later, but killing and falling from the building, most people think that they happened at the same time, but in fact they may not be happening at the same time! As long as the murderer leaves here before Li Feifan falls from the building, and let people see him in other places, Then let Li Feifan fall from the building! Then he will have sufficient evidence of alibi, and the suspicion will be ruled out!!"

Zhan Zhao nodded in satisfaction, Bai Yutang was indeed smart, not only understood his train of thought, but also followed his train of thought.

"However, the number 135 is the key!" Zhan Zhao continued, "This set of numbers directly points out the murder scene, and exposes the murderer's intentions! In other words, this set of numbers was indeed written by Li Feifan himself!"

Bai Yutang pondered for a while: "In other words, after the murderer left, Li Feifan was not dead, but he could not save himself. The only thing he can do is to leave this set of messages!"

Looking at the window sill and the guardrail outside the window, Zhan Zhao suddenly said, "When you jumped in just now, I suddenly thought of something."

Bai Yutang looked out along Zhan Zhao's line of sight, "You mean... there is just enough space for a person to be placed between the window sill and the guardrail?"

Zhan Zhao said bitterly: "Maybe... Li Feifan just lost consciousness for a short time at that time, and then he was put on it."

Bai Yutang patted Zhan Zhao's shoulder reassuringly, sighed and said, "As soon as he wakes up and moves his body, he will definitely fall, and the moment he fell, he left us this message."

"It's too cruel. He's just a child. Who wants to hurt him like this?"

Seeing the pain on Zhan Zhao's face, Bai Yutang pulled him over, leaned on his shoulder, and said slowly, "Cat, you can't do this job alone!"

Zhan Zhao's body trembled: "Two people?"

Bai Yutang caressed his hair: "You've already thought about it, right? After Li Feifan entered the building and before he fell, two people came out of the building at the same time..."

"Professor Xu and Dr. Zhang..." Zhan Zhao said in a bit of confusion, "Theoretically it is...just."

"Cat!" Bai Yutang cupped Zhan Zhao's face, stared into his eyes and said earnestly, "Do you still remember what that Doctor Xu said just now?"

Zhan Zhao opened his eyes wide in surprise, and said helplessly, "He said that Professor Xu was sweating all over his body..."

Bai Yutang nodded: "Having a heart attack doesn't mean you're sweating all over, right?... That kind of exercise is really too much for an old man! That's why he's panting non-stop and shaking all over... And the one who faked the scene should have It's Dr. Zhang. The two of them, kill Li Feifan!"
