"Isn't this simple?" Deng Chao pointed to the fracture of the beam and said: "This fracture is uneven, obviously a natural fracture, not a knife cut." Because, when the knife is generally cut, no matter how shallow the cutting position is, it will definitely leave a smooth fracture on one side. On this beam, there is obviously no such smooth fracture. ”

Deng Chao's words made everyone focus on the fracture, and the men and women in a circle immediately stared at it, and at a glance, they found that it was consistent with Deng Chao's statement.

"Well, if you add this bloody handprint, then it's more like a female ghost, right?" Zhao Yongqi casually pointed to a large section of beams and pillars that fell to the ground, and said with a smile. But before his words fell, the girls standing near the piece of wood were startled, and they almost exclaimed.

Cheng He frowned, squatted down and looked at it for a long time and said, "It's really a bloody handprint, I thought something was dyed with flowers." ”

"This bloody mudra is made of real blood. As soon as Zhao Yongqi's words sounded, the girls around him were huddled together, and their little faces turned pale.

"Food, cannibals, don't lie to people. Feifei stepped forward boldly and took a closer look at the speckled marks on the wood, swallowed his saliva, and then turned back and stared at Zhao Yongqi with wide eyes.

"It is indeed real blood, and it is most likely human blood. But ......" Zhao Yongqi pointed to the piece of wood with a serious face, and said in a deep voice: "The more real blood, the more it shows that this is not a female ghost, but a man-made!"

"Artificial?" Everyone was stunned, and Cheng He asked first: "Xiao Qi, what evidence do you have." ”

"It's simple. Zhao Yongqi said with a smile: "According to the legend, if a female ghost asks for her life or something, the bloody handprints left behind must be as red as blood, how can it start to be black and stinky because of too much time? Obviously, the real murderer wants to pretend to be as real as possible, and I don't know where to get the plasma." But he didn't have any common sense, and after completing the bloody handprint, after a period of time, it became a black and smelly smudge like this, which was also the fundamental reason why it did not attract the attention of the crew members. To be honest, he is completely painting snakes, it is better to paint one directly with red paint, and it can also play a role in scaring people. Think about it, who would pay attention to a blackened blurred handprint on the top of a beam in such a dilapidated log cabin that could be blasted at any moment? Even if someone did see it, it would probably be a construction worker who accidentally brought the mud handprint, right?"

Hearing Zhao Yongqi's analysis, everyone nodded one after another, at least if they entered the cabin by themselves and saw a blackened handprint, it would not be associated with the bloody handprint used by the female ghost.

"That bloody handprint has nothing to do with the collapse of the cabin? After all, it looks like the collapse of the cabin was an accident, not like it was vandalized. Deng Chao said with a frown.

Zhao Yongqi nodded and said approvingly: "Whether this bloody handprint is related to the collapse of the cabin is not certain for the time being." However, this was definitely not an accident, but someone deliberately sabotaged it, which caused it to collapse prematurely. Even I estimate that the time of this collapse is earlier than the real culprit hoped. ”

"Ah?!" A group of people around immediately stared at Zhao Yongqi's handsome face with a confident face.

Zhao Yongqi didn't sell it either, pointed to the fracture and said: "You judge that this is not the root cause of the destruction, probably because there is no smooth fracture on this fracture." ”

Looking at the dotted heads around him, Zhao Yongqi said with a smile: "Everyone, we are not in ancient times, but in modern society. Do you have to have a knife to break the support of a wooden structure?"

"Brother Qi, tell me ......" Xiao Baozi reacted the fastest, and shouted out first as soon as his eyes lit up.

Nodding slightly, Zhao Yongqi pointed to the fracture and said: "Using diluted strong acid, or strong alkaline liquid, and constantly spraying the liquid in the same position, can make the wood soften and loosen, and its appearance can only appear small holes that can be observed under a microscope." In other words, it is difficult to determine from the appearance with the naked eye alone. Also, if there are painted beams on the outside, then the paint and the solution may have a chemical reaction, resulting in a noticeable blackening and discoloration. However, on this rough and unprocessed log, the performance is less impressive. Finally, there is another conclusive evidence, and that is that the wood near the fracture is very soft. ”

As he spoke, Zhao Yongqi's fingers pinched the uneven burrs on the broken part of the beam, and with a slight rub of his thumb and index finger between them, the small piece of wooden thorns turned into powder.

A group of men and women who had been completely interested immediately surrounded them, big hands and small hands went into battle together, and after a while, they all nodded excitedly, indeed as Zhao Yongqi said, the wood near the fracture was already like weathering and easy to turn into debris.

"Frog Oba, you're so amazing!" Li Zhien rubbed to Zhao Yongqi's side and said with admiration on his face: "How do you know that this wood is broken like this?"

Smiling and touching the girl's head, Zhao Yongqi stretched out his hand and pointed around, chuckling and said, "Because the collapse scene here is too strange." ”

"Hmm, what's strange, why didn't people see it?" Li Zhien's little head turned around and scanned for a long time, and finally fell on Zhao Yongqi's body.

Zhao Yongqi smiled and saw the sunglasses in his hand standing in the palm of his hand, and then pointed to the sunglasses and said, "This is now the beam that supports the house on all sides." If one of them falls, no matter which way it falls, it will surely take the whole wooden house to one side. In other words, most of the wreckage after the fall could not have landed in the center of the cabin. And now at this site, don't you look like a professional blast with all the wreckage left in the center after being targeted blasted?"

Hearing Zhao Yongqi say this, everyone discovered that with the four largest pillars around it as the boundary, almost the entire superstructure of the cabin collapsed within the range they enclosed.

Seeing that everyone seemed to understand what they meant, Zhao Yongqi continued to explain: "Since the scene is not the result of directional blasting, then there is only one possibility left. That is, the four beams and columns that support this small cabin, and there is no way to continue to support the weight on them, and they are really crushed! If you think about it along this line, then there must be something wrong with the support itself. When I saw the four pillars, I made sure that the lower part of them was solid, and at least there was no possibility of being overwhelmed and crushed at the same time. The only reason that remains, then, is that there is some kind of change in the support near the fracture, or on the upper level, that they can no longer support the wooden house. Now it seems that the conclusion is the same as my reasoning, that the area near the fracture was corroded and softened by some solution or other means, which led to the collapse of the cabin!"
