Gu Chen held a strong flashlight and walked step by step towards the edge of the rooftop.
Lu Weiwei on the side saw the clues and quickly reminded Gu Chen: "Junior Brother Gu, be careful where you step."
"Senior Sister Lu, what do you think the purpose of this pile of bricks here is?" Gu Chen stopped in front of the pile of bricks and turned to ask Lu Weiwei beside him.
Lu Weiwei followed Gu Chen's pace, hesitated for a few seconds, and then replied: "It can be seen from the origin of these bricks that they are used as insulation layers."
"The insulation layer of the roof of these old houses from decades ago was supported by these bricks and then covered with cement boards."
"But judging from the scene, it is obvious that the insulation layer was deliberately damaged. As for what the purpose of these bricks were discarded on the edge of the rooftop? This... I really don't know."
"If you want bricks, you don't have to remove the insulation layer. You need to lift off the cement board and then get the bricks. It's superfluous. If it's downstairs, it's easier to just demolish a wall."
Gu Chen also picked up one of the moss-covered bricks and expressed his opinion.
Lu Weiwei moved slightly to the edge of the rooftop, then stretched out her head and looked downstairs.
At this moment, Xu Feng, Officer Wang and Yuan Shasha were there.
In front of a few people was a pile of ruins.
Lu Weiwei hesitated for a moment and murmured to herself: "The bricks are piled up on the rooftop, are they meant to be thrown down?"
Thinking of this, Lu Weiwei quickly glanced at Gu Chen.
Gu Chen also agreed with Lu Weiwei's words and said: "You can see from the edge of the rooftop that the surrounding area is very clean. Except for some moss growing on the entire edge of the rooftop, there is almost no debris."
"But this is the only place where there are a bunch of bricks. It's obviously very likely that these bricks will be thrown down."
"Then if there's someone else down there..."
"If there is someone down there, if they are hit, then..." Lu Weiwei thought of this based on the ideas provided by Gu Chen, and suddenly felt a chill in her heart.
"I understand." Lu Weiwei frowned slightly and said with wide eyes: "This pile of bricks was removed from under the cement board of the insulation layer and piled on the edge of the rooftop, perhaps to attack passers-by downstairs."
"And why do you prepare so many bricks at once? Maybe the brick movers think that they may not be able to solve the problem with just one brick, so they move a bunch of bricks. Is it understandable?"
Gu Chen nodded silently: "That's about right. Let's go together."
"If idiot Liu Chengjun's head was really hit by this brick, then maybe he would lie in the ruins with a bloody head, and then be discovered by passers-by and call the police."
"Then if this is the case, Liu Chengjun is very likely to be injured, and there should be obvious scars on his head."
"But if the person who was attacked was Jiang Tianci, and after being hit, he died on the spot, lying in the rubble, and was discovered by passers-by, and then called the police."
"But if the perpetrator moved Jiang Tianci's body to another location before the police arrived, then there would only be a pool of blood left at the scene, and Liu Chengjun's injury seemed to be a disguise. Perhaps Jiang Tianci's disappearance was related to
He can't escape the relationship."
Gu Chen also suddenly thought of many possibilities from a pair of bricks placed on the edge of the rooftop.
After Lu Weiwei heard this, her thoughts seemed to become clearer.
Gu Chen's analysis didn't make sense.
First of all, how could the bricks in the rooftop insulation layer appear on the clean edge of the rooftop? Apparently someone did it on purpose.
But why are they piled here? It seems that the purpose is somewhat obvious, which is to throw them down from the rooftop.
Secondly, who would be stupid enough to stand under the rooftop and be willing to get smashed? He was obviously invited here.
From this point of view, Lu Weiwei and Gu Chen wanted to go together.
At this moment, Gu Chen handed the bright flashlight to Lu Weiwei, while he picked up the bricks in his hand and gently pushed away the moss with his hands.
Gu Chen then came to the side of the rooftop, found the correct location, and shouted to Officer Wang downstairs: "Brother Wang, please pay attention to the specific placement of the bricks later."
"Understood." Knowing that Gu Chen was going to throw something downstairs, Officer Wang agreed and quickly asked Xu Feng and Yuan Shasha to stand farther away.
Just a moment later, a brick fell from the sky and landed in the ruins in front of him with a "bang" sound.
"Okay, I've seen it." Officer Wang downstairs said.
Seeing this, Gu Chen glanced at Lu Weiwei beside him and said, "Let's go down."
The two of them walked along the way they came, all the way to the first floor.
At this moment, Officer Wang, Yuan Shasha and Xu Feng also trotted over.
Officer Wang hurriedly asked: "Gu Chen, what did you find on the rooftop?"
"A pile of bricks." Gu Chen said.
"A pile of bricks?" Officer Wang was a little confused.
But Gu Chen continued to add: "To be precise, it's 50 bricks piled on the edge of the rooftop."
"50 yuan? Do you know this?" Xu Feng showed a strong interest in Gu Chen's remarks.
Even Lu Weiwei on the side was startled and hurriedly asked Gu Chen: "Junior brother Gu, I didn't even pay attention to the rooftop we went to together just now. How many bricks were piled there in total, but you remembered them all, but
What’s the use of remembering this?”
"Yes, what's the point of memorizing bricks, Senior Brother Gu?" Yuan Shasha on the side also expressed confusion.
After all, Gu Chen's thinking is sometimes difficult for people to understand.
Gu Chen said calmly: "To be precise, the number of bricks originally piled on the edge of the rooftop should be 60, but unfortunately, 10 of them may have been thrown away a few years ago.
downstairs."
"And of the remaining 50 bricks, I just dropped another one, and now there are only 49 bricks left."
"Hey, why don't you wait a moment." Xu Feng felt a little confused and waited for two seconds before quickly asking Gu Chen: "Speaking of Gu Chen, how did you count how many bricks there were in front of the edge of the rooftop? They were thrown down again.
How many bricks? How did you calculate that?"
I felt that from the first moment I met Gu Chen, I was impressed by this young policeman.
After all, he can accurately guess his identity through the eating movements of his little finger.
But now I have to list this bunch of numbers that I don’t understand, which is really nerve-wracking.
Seeing that Xu Feng didn't know, and the others didn't understand either, Gu Chen just smiled faintly and then explained:
"It was only after I went up to the rooftop that I checked the structure of the rooftop insulation layer and found out that the insulation layer here is all made of bricks as pillars and cement boards as insulation boards."
"Yes, aren't all old buildings insulated like this?" After all, he knew the principle and structure, so Xu Feng was not surprised.
What he urgently wants to know now is how Gu Chen deduced these numbers.
Gu Chen also said calmly: "I did some calculations. Each of these insulation columns made of bricks is made of 6 bricks."
"Just now, Senior Sister Lu and I went upstairs to check. I found that the other insulation layers were relatively intact, but only the edge of the rooftop was damaged."
"Then I counted them carefully. A total of 10 insulation pillars and bricks were moved aside. The structure of 10 pillars is 60 bricks."
"And I just checked the bricks on the edge of the rooftop. There are only 50 bricks in total, which means that at least 10 of them are missing."
"Then let's analyze it again. Where will these 10 bricks be taken?"
"Throw it downstairs?" Yuan Shasha said.
Officer Wang also nodded slightly and echoed: "Since these piles of bricks are piled on the edge of the rooftop, they are obviously going to be thrown downstairs, just like what you did just now."
"Yes, I think so too." Gu Chen didn't explain much as he spoke.
Instead, he walked straight to the place where he had just dropped the brick, and quickly found the brick he had just dropped.
Since Gu Chen used his fingers to wipe out traces of the moss on the surface of the brick, he was able to quickly find the brick just now among the pile of waste.
At this moment, the brick just thrown to the first floor had been broken into two pieces.
Gu Chen casually threw the two and a half bricks aside.
After that, Gu Chen found some other broken bricks among the ruins one after another.
Since they were all relatively close together, apart from the marked brick just now, Gu Chen found a total of 20 half-bricks one after another, which together amounted to 10 complete bricks.
Gu Chen threw the bricks together, patted the dust on his hands, and then said: "I counted, and together with the piece I just dropped, we can make a total of 11 bricks."
"Including the 49 bricks upstairs, we can get just 60 bricks. This shows that these bricks were removed from the insulation layer on the rooftop."
"Oh my God! Can you still operate like this?" Seeing Gu Chen's magical operation, Xu Feng on the side was also shocked and stunned.
After hesitating for a moment, Officer Wang quickly asked Gu Chen: "So Gu Chen, your idea is that the reason why these bricks were thrown from the building was because someone called the police and said that someone was found in the ruins.
Lying in a pool of blood, could it be that he was injured by these bricks?"
"It's very possible." Gu Chen walked up to the pile of broken bricks and couldn't help but said: "Although several years have passed, if these bricks are tested again, not much useful value can be obtained, but at least it can
Tell us something."
Turning around, Gu Chen pointed to the rooftop location just now and said with a serious face: "At least it means that someone pried open the bricks of the rooftop insulation layer and smashed at least 10 of them to the ground."
"And the man who fell in a pool of blood may have been blessed by this brick. As for the rubbish falling and hitting his head, it's nonsense. I've checked the structure of the building. As long as the wall is not violently smashed with a sledgehammer, it doesn't matter at all.
What kind of waste might fall out?"
"It can be seen that what happened to Liu Chengjun was very strange at the beginning."
"What do you mean?" Xu Feng heard what Gu Chen said and seemed to feel that what happened that year was full of doubts.
Naturally, Gu Chen didn't hide it and asked Xu Feng directly: "Officer Xu, let me ask you, if you were standing downstairs right now and were hit directly with a brick from the rooftop upstairs, what would you do?
What do you think your situation will be like now?"
"He must have fallen to the ground, or he would have lost half his life." Xu Feng answered concisely and concisely.
Gu Chen also nodded silently and asked: "What if you are attacked by 10 bricks in a row?"
"Then...then this is a deadly move?" Xu Feng instantly understood what Gu Chen meant.
Lifting someone else's brick is not the goal at all, continuous attacks are the goal.
Otherwise, we wouldn't have pried out 60 bricks from the rooftop insulation layer.
Wouldn't this lead to death?
Thinking of this, Xu Feng was also frightened at this moment, and said hurriedly: "If this is the case, once the head is hit by a brick, it will be half-life or not, and the head area will definitely leave a deep wound."
Glancing at Gu Chen, Xu Feng added: "And if there are no so-called wounds on the head of idiot Liu Chengjun, it may mean that his injuries back then were just an illusion to confuse the police.
That’s it?”
"Yes." Gu Chen nodded slightly and agreed with Xu Feng's words: "That's how I understand it too."
"After all, someone called the police and reported that someone was found lying in a pool of blood in the ruins here."
"We can make a bold assumption that someone was attacked here. He was attacked with bricks from the rooftop and instantly fell into a pool of blood. The murderer had not yet moved his target."
"But at this time, someone happened to be passing by the roadside and found this character lying in a pool of blood."
"But because this person was timid and fearful, he was depressed after playing cards, and he drank a small amount of alcohol, so we had no choice but to call the police on the spot."
"But after calling the police, I didn't dare to approach without authorization, and all this happened to be seen by the attacker."
"At this time, what is the only thing the attacker can do? Have you ever thought about it?"
"Shift target?!"
Just as Gu Chen finished speaking, the other four people almost spoke in unison.
Gu Chen snapped his fingers: "Yes, the only thing the attacker can do is to quickly move the target before the caller approaches the target and the police have not arrived at the scene."
"Only in this way will the police fall into a passive situation while conducting investigations after they arrive later."
"In addition, the person who called the police couldn't explain clearly, and later the fool Liu Chengjun appeared in the factory with a bandage on his head, and then changed from a normal person to a fool. Only then can the police believe what the person who called the police said that day.
The situation does exist.”
"And the character lying in a pool of blood may be Liu Chengjun, so there is an extra fool in the factory."
"It's too scary." When Yuan Shasha heard Gu Chen's words, she couldn't help but take a breath and said with fear:
"If Brother Gu's reasoning is true, then the only suspect is undoubtedly this idiot Liu Chengjun."
"And if Liu Chengjun pretends to be stupid in order to conceal his purpose of killing, that seems to make sense."
"But if we want to prove that fool Liu Chengjun is indeed the assailant that night, he has to go to the hospital to have his head examined. If there are no fatal injuries, it means that Liu Chengjun is just pretending to be stupid."
"Yes." Lu Weiwei also took a step forward and said with certainty: "And the date when Liu Chengjun was injured in the accident is very close to the date when Jiang Tianci disappeared."
"If it were more accurate, it might be the same day and night. How could it be such a coincidence?"
"If it was Jiang Tianci who was attacked, then the attacker Liu Chengjun would definitely find ways to shift the target."
"In order to avoid making the police suspicious, he had to act as the victim. Only in this way can everyone believe that Jiang Tianci's disappearance had nothing to do with Liu Chengjun."
After the words fell, the scene was also silent.
Everyone is thinking about these questions just now.
Gu Chen took a pile of bricks on the rooftop as a clue and quickly found the missing quantity downstairs.
From this, I can deduce for everyone what happened here that night.
Coupled with Gu Chen's detailed explanation, in fact, everyone has a strong sense of picture in their minds at this moment.
It must be true that the injured person fell here. After all, after the caller called the police, the police also found a lot of blood at the scene.
But if this victim is Jiang Tianci, then Liu Chengjun can never be the victim.
Thinking of this, Officer Wang couldn't wait anymore and said bluntly: "I propose that Xu Feng take action and let your people from the police station take this Liu Chengjun back for examination."
"I still don't believe it. How could he have that kind of fatal wound on his head? If he had been hit by a brick thrown from upstairs, his skin would have been bruised and there would have been obvious and irremovable scars."
"As long as we take him back and check him out, everything will come to light."
Glancing at Xu Feng, Officer Wang also said bluntly: "Officer Xu, I'll leave this matter to you."
"Of course there is no problem with this." Xu Feng crossed his arms and was also shocked by the situation at the scene.
In a case that happened a few years ago, Gu Chen could find so many problems just by walking around on the rooftop of an abandoned building.
As for yourself, what have you been doing these past few years?
The case of missing persons was left undisturbed, without even focusing on verifying the situation back then.
Including whether Liu Chengjun was really injured? Did those blood stains really come from Liu Chengjun’s wounds?
Thinking of this, Xu Feng also looked annoyed. He felt that Gu Chen, a young man, had arranged everything clearly as soon as he arrived, and he had become his little follower.
Not convinced?
Don’t accept it! That’s where my insight lies.
Xu Feng was a little jealous at the moment, not that he was petty, but just jealous of Gu Chen's super insight.
A large number of problems can be inferred from just one small clue.
But if these questions are correctly verified in the end, wouldn't Gu Chen want to become a god?
Thinking of this, Xu Feng couldn't help but sigh, he is really different from these young people now.
He worked hard in the undercover field, but Gu Chen seemed to be able to catch up with himself just because of his good brain. This seemed unfair.
