Just as Feng Yan was about to walk out of the big classroom and the door was accidentally closed and locked, Yiye crossed the river and completed his reasoning. Pen ~ fun ~ pavilion www.biquge.info

"I know what the murder weapon is." Yiye crossed the river and said this sentence with confidence.

Nan Nan's voice came from the air: "I'm listening." ”

"The murder weapon is a piece of soap, the kind of yellow soap that has no fragrance, just like ......" Speaking of this, Ye Dujiang returned to the bathroom again, pointing to the large and empty soap box on the washstand and continued, "Such a big one. ”

Ding Dong, the system's prompt appeared, prompting that Yiye crossed the river, and the side quest had been completed, that is to say, the task of accompanying Nan Nan to play the game had been completed, and according to Nan Nan's game rules, it was necessary to guess the murder weapon correctly, that is, Yiye had guessed correctly across the river.

Nan Nan's somewhat funny voice came from the air: "Soap can also kill?" I heard you right. ”

Although Nan Nan's acting skills are very good and her laughter is very contemptuous, first, the system has admitted that Yiye crossed the river to win, and secondly, even if there is no systematic prompt, Yiye is very sure that Yiye crosses the river, and his answer is definitely right.

"Why can't soap kill? The kind of soap we use in our daily life, there is the kind whose hardness is second only to ice, this kind of soap will break the head when it hits the head with a violent force in an instant, and if it hits a more fragile position similar to the Tianling cover or the back of the head, it will definitely be fatal, not to mention...... The deceased also endured several heavy blows. ”

Nan Nan was silent for a moment and said, "Why don't you guess the ashtray, paperweight, or artwork, these three things are obviously lethal things." ”

Ichiha Dujiang held his left hand in front of his chest, put his right elbow on the back of his left hand, made a movement similar to Ultraman's laser, and tapped his temple with his right index finger and said, "Because if it is these three things, then the temperature of the air conditioner in the house is so high, it cannot be explained." ”

Yiye Dujiang simply said the inference in his heart just now, 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 disappear, and this thing will disappear in high temperatures, so what kind of things will disappear when the temperature is too high?" There is only one answer: water. Then my first guess was that it was ice, ice cubes are another form of water, and they are also the hardest transformers transformed by water, but this answer was soon 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 some objects that were not as hard as ice, so I started to check the abnormal state of all the items in the room again. ”

Yiye Dujiang pointed to the large soapbox on the washstand and said: "When I first came in, I noticed this empty soapbox, it's very strange, there is a soapbox that is only one size smaller than the bricks, and it is still empty, I was thinking, where did the soap go?"

Putting aside this dispensable clue for a moment, I began to continue to check all the items in the bathroom, but alas, the bathroom is so big, everything seems to have its use, except for one thing that is dispensable, and that is the basin. ”

Yiye Dujiang pointed to the washstand and continued: "This is an office, not a residence, and it is no problem to design a bathroom in the office, but people who work in this office should not spend the night here, right?" Well, there are a few towels hanging on the wall, and I assume that occasionally because I work too late and this leader in the office is too tired, I choose to spend the night here, and lie down on the sofa. So when he wakes up the next morning, what will be the whole process of getting a towel and washing his face? ”

Seeing that Nan Nan didn't mean to interact with herself, Yiye crossed the river and shrugged her shoulders and said: "You must be holding a towel and dipping it in some water and wiping your face indiscriminately, even if you like more water, you should also plug the hole in the washbasin and store some water to wash your face, and you will never use the basin." ”

Nan Nan spoke at this time: "The washbasin usually has to be used to wash hands and flush ashtrays and the like, it will be dirty, the owner here may not choose to wash his face with water in the washbasin, and in addition, when it comes to winter, he definitely needs a water storage container to put some hot water to wash his face, and the washbasin is the best water storage container." ”

Yiye Dujiang nodded: "What you said is completely correct, I just look at the problem from the perspective of how the vast majority of people will choose, and what you said, it is also possible, although this washbasin is also very clean, but it is not excluded that the owner of this office loves cleanliness very much." ”

After a pause, Ye crossed the river and walked to the side of the basin, first pointed to the basin and said: "But can you tell me, why does a person who loves cleanliness lean his face plate against the corner of the toilet, and urine will splash on it when he pees, and this basin is not half clean of the washbasin, and the internal color is black, which is obviously a manifestation of long-term ash, like something that is often used?"

I didn't mean to deny your statement, so I just said at the beginning, the basin is a dispensable thing, so in such a small bathroom, most of them are reasonable items, but there is such a not very reasonable item, should I focus on studying this unreasonable item? ”

This method of elimination is learned from Sherlock Holmes: eliminate all impossibilities, and the rest of the impossibilities are also the truth!

Although it is impossible for him to have such a realm, the simple method of elimination is still no problem.

"Empty soap boxes, unreasonable washbasins, very hot offices, carpeted floors, and murder weapons that will disappear. Combining these keywords, I had an idea in my head and came up with a bold guess. ”

Yiye crossed the river and quickly tapped on his temple and said: "In order to verify my guess, I carefully observed the basin again, and found that the lower part of this dirty basin is cleaner than the upper half, and there is a relatively obvious water mark at about half of the overall capacity.

So what kind of liquid is in the basin that causes water marks? Ordinary water will never produce water marks, only water with impurities has been placed in the basin for a long time, and water marks will be formed at the circle position calculated by the height of the water surface. From this I can deduce that this basin was used not long ago, and it contains about half of the basin's water, and it is also water with impurities.

Then I thought about the question: what kind of impurities can water have a cleaning effect? Obviously, the lower part is cleaner, and the unlucky upper part that is not clean 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 that the killer slammed the deceased from the back of the back with soap, smashing him several times to death, and then used the basin to put a basin of water...... Hot water is more likely, and then put the soap into this half basin of water, or wait for it to melt naturally, more hurried, just rub the soap with your hands, but what, this murderer may not be an acute child, he should have chosen to wait for the soap to melt slowly, so during this period, the water surface is still, for a long time, water marks are generated, and the lower part of the basin is much cleaner than the upper part due to long-term soaking. ”

"It's all your guesses, that's all you have."

Nan Nan's voice was a little annoyed, she heard Yiye Du Jiang's calm reasoning, and felt that the illusion space she had established was a failure, so she was very angry.

Yiye Dujiang was not annoyed, he shrugged his shoulders again and said: "Of course, these are my conjectures, and further practice is needed, I thought of what you told me when I first entered this sealed office: The murder weapon is in this room.

This sentence immediately reminded me of the last question: where did the water in that basin of melted soap go? ”

Yiye Dujiang raised his eyebrows at the air and said, "That basin of water will definitely not be flushed into the toilet or washbasin and flow into the sewer, because if this is the case, the melted murder weapon will not be in this room by your definition." ”

Yiye crossed the river and stretched out a finger: "First of all, so much water, it is impossible to evaporate naturally, how long will it take?" It doesn't make sense, and it can't flow into the sewer, so where does the water go? ”

Back in the office, Yiye crossed the river's feet on the carpet and stomped a few times and said: "If the water is evenly sprinkled on the carpet, and then the temperature of the air conditioner is adjusted to the highest, it only takes a few minutes to make the water disappear without a trace, but from your general meaning, the murder weapon turned into soapy water still remains in the carpet, and it also exists in this room."

But half a basin of water is not much, the murderer can not fall in a position at once, can only take the basin in the house to sprinkle water, the area of this room is not small, this half basin of water is impossible to sprinkle all over this room, so I lie on the ground again inch by inch to touch the carpet, I found that the carpet of the whole office, some places are a little gray, rub with your fingers, your fingers will be black, more dirty, but in some places after rubbing with your fingers, you will obviously find that there is a sense of frustration, which is the cleaning effect of soapy water. ”

Yiye crossed the river and shook his index finger twice towards the void and said: "Speculation and practice, and finally came to the conclusion that the murder weapon was soap." In fact, you are also quite cunning, not only set the soap to the kind of soap without any fragrance, so that I can't judge that the murder weapon is a piece of soap by the taste, but also use the murder weapon in this room to induce me, but unfortunately in the end it became the key information of my practice, ha, it's really enjoyable. ”

In the last sentence, crossing the river in one leaf certainly 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 the No. 2 teaching building, and Nan Nan stared at him with an angry face.
