Just when Feng Yan was about to walk out of the big class classroom and the door was unexpectedly closed and locked, Yiye Dujiang also completed his reasoning.
"I know what the murder weapon is." Yiye Dujiang said this with confidence.
Nan Nan's voice came from the air: "I'm listening."
"The murder weapon was a piece of soap, a big yellow soap without fragrance, just like..." At this point, Ye Dujiang returned to the bathroom again, pointing to the large and empty soap box on the sink and continued: "Such a big one."
Ding dong, the system prompt appeared, indicating that Yi Ye Crossing the River, the side task has been completed, that is to say, he has completed the task of playing games with Nan Nan, and according to Nan Nan's game rules, he must guess correctly As for the murder weapon, in other words, Yiye Dujiang guessed it correctly.
Nan Nan's somewhat funny voice came from the air: "Soap can also kill people? Did I hear it right?"
Although Nan Nan's acting skills are very good and her laughter is very contemptuous, firstly, the system has admitted that Yiye Dujiang has won, and secondly, even without the system's prompt, Yiye Dujiang is still very confident, and his answer is definitely right. .
"Why can't soap kill people? The kind of soap we use in daily life has a hardness second only to ice cubes. If this kind of soap hits the head with sudden force, it will break the head. , and if it hits a relatively fragile position like the Tianling Cap or the back of the head, it will definitely be fatal, not to mention... the deceased also withstood many violent blows."
Nan Nan was silent for a moment and said, "Why don't you guess an ashtray, a paperweight, or a work of art? These three things are obviously lethal."
Ichiyo Dujiang held his left hand in front of his chest, put his right elbow on the back of his left hand, made an action similar to Ultraman firing a laser, tapped his temple with his right index finger and said: "Because if it is these three things , then it cannot be explained that the temperature of the air conditioner in the house is so high."
Yiye Dujiang simply expressed what he had just inferred, and continued: "If the temperature of the air conditioner is too high, it indicates that the murder weapon is something that can be melted or disappeared. This thing will disappear at high temperatures, so it will What kind of things will disappear when the temperature is too high? There is only one answer: that is water. So my first guess is ice cubes. Ice cubes are another form of water and also use water as a carrier. The transformation body with the highest hardness was transformed, but this answer was quickly rejected by me, because the blow to the back of the deceased's head was not caused by something as hard as ice, but by something as hard as ice. It was caused by a block of objects, so I started checking all the items in the room again for abnormal conditions.”
Ichiba Dujiang pointed to the large soap box on the washbasin and said: "When I first came in, I noticed this empty soap box. It's strange that there is actually a soap box that is only one size smaller than a brick. The soap box was still empty. At that time, I was thinking, where did the soap go?
Putting aside this dispensable clue for the time being, I continued to look at all the items in the bathroom, but unfortunately, the bathroom was only so big, and everything seemed to have its use, except for one thing. What is optional is the washbasin. "
Ichiba Dujiang pointed to the washbasin and continued: "This is an office, not a residence. There is no problem in designing a bathroom in the office, but the people who work in this office shouldn't spend the night here, right? Okay. , there are a few towels hanging on the wall. I assume that occasionally because of working too late, the leader in the office is too tired and chooses to spend the night here directly, lying down on the sofa. Then when he wakes up the next morning What would be the whole process of taking a towel and washing your face?”
Seeing that Nannan had no intention of interacting with him, Yiye Dujiang shrugged and said: "You must have taken a towel and dipped it in some water and wiped your face randomly. Even if you like more water, you should have wiped the hole in the sink Plug it and save some water to wash your face, you will never use the basin.”
Nan Nan spoke at this time: "The wash basin is usually used to wash hands and flush ashtrays, etc., so it will be dirty. The owner here may not choose to store water in the wash basin to wash his face. In addition, in winter, he will definitely You need a water storage container to put some hot water in to wash your face, and a washbasin is the best water storage container.”
Yiye Dujiang nodded: "What you said is absolutely correct. I only look at the problem from the perspective of how most people would choose. As for your statement, it is also possible that although this washbasin is also very clean, It cannot be ruled out that the owner of this office loves cleanliness very much."
After a pause, Yiye crossed the river and walked to the basin, pointed at the basin and said, "But can you tell me why a person who loves cleanliness would lean the wash basin against the corner of the toilet? Urine will splash on it when you pee, and this washbasin is not half as clean as the sink. The inside is black, which is obviously a sign of long-term dust accumulation, as if it has been used frequently. ’s stuff?
I don’t mean to deny what you said, so I just said it at the beginning. The washbasin is a dispensable item, so in such a small bathroom, most of them are reasonable items, but they have such An unreasonable item. Should I focus on researching this unreasonable item? "
This method of elimination was learned from Sherlock Holmes: eliminate all impossibilities, and whatever remains is the truth no matter how impossible it is!
Although it is impossible for him to have such a realm, the simple elimination method is still no problem.
"An empty soap dish, an unusual washbasin, a very hot office, a carpeted floor, and a disappearing weapon. Combining these keywords, I came up with an idea. A wild guess."
Yiye Dujiang quickly tapped his temple and said: "In order to verify my guess, I carefully observed the washbasin again and found that the lower half of the dirty washbasin was cleaner than the upper half, and at about There is a relatively obvious water mark at half the overall capacity.
So what kind of liquid will cause water marks when filled in the basin? Ordinary water will never produce water marks. Only water with impurities left in the basin for a long time will produce water marks in the circle calculated by the height of the water surface. From this, I can infer that this basin has been used by someone not long ago, and it was filled with about half of the water in the basin, and it was still water with impurities.
Then I thought about another question: What kind of impurities can water contain to clean it? Obviously, the lower part is cleaner, but the upper part, which has been unclean all year round, is still dirty. So the water in the basin must have a cleaning effect.
Combined with the empty soap box, my answer is: the murderer used soap to hit the back of the deceased's head from behind, hitting him multiple times to death, and then used the basin to put a basin of water...hot water is more likely, Then put the soap into the half basin of water, or wait for it to melt naturally. If you are in a hurry, just rub the soap with your hands continuously. However, this murderer may not be impatient. He should have chosen to wait for the soap to melt slowly. , then during this period, the water surface is still. Over time, water marks will appear. The lower part of the basin is much cleaner than the upper part due to long-term soaking. "
"These are just your guesses. You only have so much ability."
Nannan's voice was a little angry. She heard Yiye Dujiang's calm reasoning and felt that the illusory space she had established was a failure, so she was very angry.
Yiye Dujiang was not angry. He shrugged again and said: "Of course, these are all my conjectures and need further practice. I thought of what you said to me when I just entered this sealed office. Words: The murder weapon is in this room.
This sentence immediately reminded me of the last question: Where did the water that melted the soap go? "
Yiye Dujiang raised his eyebrows in the air in an extremely mean manner and said: "That basin of water will definitely not be flushed into the toilet or wash basin and flow into the sewer, because if that is the case, the melted murder weapon will not be in your definition. Zhonglai is no longer in this room."
Yiye crossed the river and held out a finger: "First of all, it is impossible for so much water to evaporate naturally. How long will it take? It is also unreasonable, and it is impossible for the water to flow into the sewer, so where does the water go? "
Back in the office, Yiye Dujiang stamped his feet on the carpet a few times and said: "If the water is evenly sprinkled on the carpet and the air conditioner is adjusted to the highest temperature, it will only take a few minutes. Let the water disappear without a trace, but in your general sense, the murder weapon that turned into soapy water still remains in the carpet and exists in this room.
But half a basin of water is not much. The murderer cannot fall down in one place all at once. He can only use the basin to sprinkle water in the room. This room is not small. It is impossible for half a basin of water to fill the room. of the house, so I lay on the ground again and touched the carpet inch by inch. I found that the carpet in the entire office was a bit dusty in some places. When I rubbed it with my fingers, it became black and dirty. But in some places, I rubbed it with my fingers. Afterwards, you will obviously feel a sense of frustration, which is exactly the cleaning effect of soapy water. "
Yiye Dujiang shook his index finger into the void twice and said: "Through speculation and practice, we finally came to the conclusion that the murder weapon is soap. In fact, you are also very cunning. Not only did you set the soap to have no fragrance, Soap made it impossible for me to tell that the murder weapon was a piece of soap from the smell, and it was also used to induce me that the murder weapon was in this room. Unfortunately, it ended up becoming the key information for my practice. Ha, it was really enjoyable."
The last sentence, crossing the river with one leaf, of course refers to the process of reasoning.
After the space was distorted, Yiye crossed the river and returned to the corridor on the second floor of Teaching Building No. 2. Nan Nan stared at him with an angry face.
