You Mingxu can't answer this. If it is a special underground space, the water quality and soil may be different from the ground. With the caution of Yin Chen, it is possible to wash away the traces.

"Do you want to arrange for someone to go to the municipal construction department to check?" Someone suggested.

Xu Mengshan looked at You Mingxu.

You Mingxu was stunned and said, "Wait." She swiped the mouse and called up the surveillance of Yin Chen's infestation at the crime scene yesterday on the computer, and then stopped on a certain screen.

It was also the picture she pondered on the back car.

"What do you think Yin Chen is doing?" She pointed to Yin Chen's finger on her ear.

Almost everyone held their breath and stared at the frame.

Because Yin Chen's movements were very small, they were very fast, and if they didn't look carefully, they wouldn't be noticeable at all. That is, it is his unconscious action. It's like if a hair falls on your face and you itch, you will definitely brush it. But you may not even realize you've done it.

Now that You Mingxu pointed to it, everyone has noticed it.

"His ears are uncomfortable." Xu Mengshan said in a deep voice.

You Mingxu nodded, yes, of course his ears were uncomfortable. But why?

One policeman said, "Otitis media? ”

Another person explained seriously: "Otitis media is a constant discomfort, it doesn't come so suddenly, it doesn't look like it." ”

"Itchy?"

"He didn't scratch it, but rubbed it a few times."

"Water in the ears?"

"Where will the water get in?"

"Shouldn't you shoot twice when you get into the water, the more you rub it, the more you go in."

……

Everyone's brainstorming, You Mingxu listened to it in her ears, but she always felt that what they said was not. I always feel that Yin Chen's appearance looks a little weird.

As if a flash of light suddenly appeared in her mind, she hesitated to speak: "You say...... Could he be, auditory hallucinations? ”

Everyone was stunned.

Xu Mengshan chewed on the word: "auditory hallucination...... Why? ”

An inexplicable intuition drove You Mingxu to continue: "What if the place where he used to stay was noisy? If he keeps arguing, then his ears will be uncomfortable, and even if he leaves that environment, he will hallucinate from time to time, so he will have such inconspicuous small movements, and he will subconsciously rub his ears to make himself hear more clearly. ”

Yes, that's what it feels like. Yin Chen's actions at that time gave her the feeling that she was not uncomfortable, but that she heard something and was shocked. There will be anomalies. What could have been the voice, at several crime scenes, that accompanied him? Makes him feel unwell?

You Mingxu continued: "The first few times we saw Yin Chen, we had never made such a small move. Can it be assumed that it was the new place he recently stayed in that affected him? ”

"It's a very noisy place...... someone thought along Xu Mengshan's previous train of thought, "could it be a basement near the railway or subway?" ”

Everyone's spirits were lifted, and one person said: "So the traces on the soles of the shoes on the car, could it be engine oil, or gravel on the railway, etc., that you are afraid of being discovered?" Stink, is it the smell of the gutter? ”

Everyone was a little eager to try, and even You Mingxu was a little moved. It's just that I always feel that something is wrong.

Basement near the railway? It seems close, but it's still a bit far-fetched. Is the noise intensity of the passing train enough to cause such a noticeable auditory hallucination? Can the smell of the sticky sewer on your body be obvious to the car wash brothers? The traces near the station are so obvious that Yin Chen has to go and clean them?

You Mingxu's palms were dripping with fine sweat. Now, perhaps, the warehouse is still filled with water, and maybe the water level has reached the chests of the five people. In other words, they actually only have one chance, concentrate all their strength, and follow this direction to investigate, in case they are wrong......

"Is there any other possibility?" You Mingxu spoke, "This answer always makes me feel problematic, it seems that the satisfaction of every condition needs to be just right." The unique marks that must be washed off, the stench, the constant noise of the environment...... "She had a vague sense that something was about to come out.

"Farmhouse?"

"Pig farms?"

Two voices said at the same time.

It was You Mingxu, and another policeman. You Mingxu was completely intuitive, her heart was shocked, she looked at the colleague, and he showed a slightly surprised look, and said: "My family is rural, what you said, the pig farm in our hometown is safe, smelly, and chaff all over the ground, and you will step on it if you are not careful." And those pigs are always mooing, and people stay there for hours, and their heads are dizzy and their ears are flowery. And you say that water pipes, exhaust fans, and such empty pig houses are very common. ”

As soon as he said this, everyone suddenly realized, and after pondering it, everyone couldn't help but get excited - but that's not the case, just like You Mingxu said, the basement next to the railway needs to meet several conditions, in fact, it needs to be coincidental. But if it is a pig house, it fully meets these conditions!

Xu Mengshan slapped the table even more excitedly: "This is this kind of place!" You can't go wrong! ”

All the detectives had a wolf-like light in their eyes. Because just a few pieces of surveillance, plus a 1-minute video, there are no other specific clues, but let them work together to deduce such a reasonable answer, can it not be exciting?

At this time, someone looked at You Mingxu.

Ears, smell, car wash, these key details, she discovered. When everyone was inclined to the railway, she remained sober, not impatient, and did not let go of other possibilities. And it is not strange that the rural colleague can think of pig farms, but she also thinks of it, can the sharpness, delicacy and explosiveness of this brain not be admired?

"Sister You is Sister You." Someone sighed.

"But......" someone said, "even if you know, it may be a farmhouse, even if it is Xiangcheng, there are many farmhouses, and there are more suburbs, and there is not much time left now, how to find it?" ”

Everyone looked at You Mingxu.

She also frowned in contemplation, and after a moment, her brow furrowed, and she said, "No, it's too easy to find." ”

Everyone was stunned.

Xu Mengshan was also thoughtful, glanced at the frozen warehouse screen on the screen, and muttered, "Yes, he has concerns......"

You Mingxu smiled knowingly and said, "That's right. You see, Yin Chen is going to live here these days, and he doesn't worry about revealing his whereabouts; He has to bring 5 hostages back, and he has to be locked up in the warehouse, release water, and go out for video, so many things in a short period of time...... He must ensure that he has absolute control over this place, that no one will be discovered, and no one will enter by mistake halfway and call the police if he finds a hostage. So, this won't be a big farm, and he can't control the big farm alone. He has been wanted for several days, and the dense police force is looking for him, but they have not found him. So he wouldn't be wandering around trying his luck, otherwise someone would have reported his whereabouts a long time ago. This small farm, most likely, he had been to before and was very familiar with it, and it was even possible that he had some kind of relationship with him. And there were very few people who originally guarded the farm, so he was able to easily take control of the farm. ”

This reasoning can be described as ingenious, but it is convincing. Everyone nodded.
