It's not that Shen Mian feels that this matter is unsolvable or needs help, but that she feels that the tacit understanding between herself and Gu Yuzhi in the game that can understand each other and put it into practice without too much communication is a very comfortable experience for her.

It's an indescribable feeling, it's kind of wonderful.

Shen Mian came out of the room, and when he went downstairs, his pace was relatively slow, so it didn't take long for him to fall to the back of the group.

Her eyes inadvertently crossed the corner of the stairs, due to special reasons during this time, the corresponding floor was not open to the public, so the entire staircase and the floor where Qiao Jiaying lived had this layer of dust that was not too thick, because the time was not too long, so it was easy to ignore if you didn't look carefully.

Just around the corner, near the base of the wall, there was a footprint that was not very clear.

Strictly speaking, footprints on stairs are a normal thing. Even the group of them just went upstairs and downstairs, leaving a lot of footprints in different directions.

However, the peculiarity of the position of this footprint is that it appears side by side against the wall, and there is no sign of the same walk next to it, as if a person appeared out of thin air on the staircase. Then leave in other directions.

The footprints in this location are a little clearer than elsewhere and should be......

Shen Mian looked up at the decorative murals on the wall.

The position of this mural is not very high, because there is a small bookcase above, and there is a small sofa on the other side of the staircase, which is a small corner where people can rest and read.

In order to meet the needs of modern people for the travel and living environment, most of the B&Bs are designed in a distinctive style, in order to compete with other people who also open B&Bs for customers, it is also a lot of money, and various careful thoughts have been added to the design of their own B&Bs.

And this corner of the staircase resembles a book corner...... Suddenly appeared here...... If the person cannot penetrate the wall directly...... The location of this wall......

Qiao Jiaying, who was still holding Shen Mian's sleeve, didn't say anything about her somewhat strange behavior, she didn't know what Shen Mian was looking at, but the hand holding Shen Mian's sleeve tightened, she always had a bad feeling about this place. Probably because of what happened.

If it weren't for the investigation, she probably wouldn't want to go back to this place for the rest of her life.

Wei Duo, who had already gone down to the next floor, turned his head and found that there was no one behind him, and followed the direction of the stairs behind him to see Shen Mian and Qiao Jiaying who stopped at the corner of the stairs.

I saw Shen Mian standing there at this time, looking up at the bookshelf above, not knowing what he was thinking.

"Sleep? What's wrong? It's time for us to go......" Wei Duo reminded in a loud voice.

What's there to see at the corner of the stairs?

"Something isn't quite right." Shen Mian shook his head at her, his gaze moving from the bookcase to the small sofa on the other side.

"Not quite right?" Wei Duo blinked suspiciously.

At the same time, the others also noticed that someone had not followed, and they also discovered Shen Mian's location.

"Did Miss Shen find something?"

You Nanxing thought of all the things that Shen Mian had shown before, and saw this and went up the stairs again. Also with the same move are Wei Duo and Xu Yizhou, who are standing together.

"The opposite side of this wall should be stuck in the middle of the two floors, which means that the upper half corresponds to the upper room, and the lower half corresponds to the downstairs." Shen Mian's gaze crossed a few people and returned to the direction before they went downstairs: "The upstairs location corresponding to this wall is exactly the room where Xiaoying lives, and the position against the wall I remember is the same cabinet, with bookshelves on top and suitcases below, that is, empty." ”

"So what?" Wei Duo raised his head and followed Shen Mian's gaze to look at the bookcase hanging above.

On either side of one wall are different cabinets, bookcases and cabinets for placing suitcases......

"There, if you look closely, there are footprints." Shen Mian stretched out his hand and pointed in a direction.

You Nanxing followed her hand, squatted down and looked carefully, Sure enough, there were faint traces of footprints.

As a criminal investigation policeman's intuition and the brainless words that Shen Mian said just now, he suddenly looked up at the bookshelf above.

It was not him who spoke first, but Qiao Jiaying, who had been standing beside Shen Mian.

"Sister Shen means that this is connected to the room where I live? That...... The man at the time was actually ...... Not out there? ”

When Qiao Jiaying said this last sentence, she felt like something was stuck in her throat, and her already pale face was even more ugly, her eyes widened, and her whole person trembled slightly because of some kind of conjecture of her own.

The most terrifying thing is "fear", which is vividly reflected at this time.

You Nanxing glanced at Xu Yizhou beside him, and the other party took out a small thing from the bag, made a mark next to the footprints, and took a photo at the same time.

And Wei Duo also realized something, the location of this bookshelf is indeed different from the ordinary bookshelf. In order to make it easier for people to read, half of the bookshelves are floor-to-ceiling, or a reading area is made directly below the bookshelf to save space.

But the bookshelves in front of them said that they were not high, and they were not low.

According to the height of women like Shen Mian and Wei Duo, it takes a lot of effort to reach it.

Underneath the bookshelf is a simple hanging painting, and the chair is placed on the other side of the bookshelf, even a little far away from the bookshelf.

You Nanxing asked people to bring a stool, stood up with the advantage of height, and reached out to knock on the positions of the inner shelf in all directions, and the crisp percussion sound echoed in the narrow space of the stairs, making everyone present realize a problem.

The back of this board is empty!

You Nanxing turned his head and gestured to Xu Yizhou and Wei Duo, and the two of them quickly went up the stairs and returned to the room they had just stayed in. In the corresponding position, the empty cabinet where Shen Mian said the suitcase was placed was found.

Wei Duo gently tapped a few times with his knuckles in various positions.

Sure enough, it was the same voice!

She carefully examined the wooden planks of the cabinet, found nothing out of the ordinary, and returned to the corner of the stairs.

"It's empty. There is nothing special next to it, but because it is written that it is specially placed for luggage, the cabinet is relatively wide. That is to say......"

"If there's a door here, it's going to be where we're now. This footprint and the sound I heard in the dream should have been someone jumping directly from it. You Nanxing muttered to himself.

After saying that, he squatted down and looked at the footprints marked on the ground: "But, if that's the case......

Shen Mian, who hadn't spoken again since just now, reminded: "Don't you guys have a sense of familiarity with this? ”

"What do you mean?"

Everyone else's eyes were refocused on her.

Shen Mian sighed a little helplessly: "If a person jumps directly to the ground from that position, the sound may not be loud enough to wake up the people in the room directly. Unless you jump on an object of a different material. For example......" Her gaze turned to the couch not far away.

The cushions on the small sofa are movable, and the cushions are a bit special, so if you want to avoid leaving footprints on them, removing the cushions is the best choice.

"You probably didn't have this footprint when you came here before, and that's probably why. And the reason why these footprints appear here now is only one possibility, that is, in the following period of time, someone came here again, and in order to save time here, they directly chose to jump to the ground, so that it is much more time-saving to deal with the footprints on the ground......"

"The other party is actually consciously removing traces, we have encountered this practice before, I think your captain should have mentioned it to you."

After Shen Mian finished speaking, he saw the thoughtful expressions of several people, and prompted: "Dust." ”

Wei Duo's eyes lit up: "The abandoned dormitory building over there in the Luna Mountain Cemetery? ”

When they first met there, someone had covered up the traces of their residence with dust.

"But since the other party would cover it up in this way, why would he leave such a mark?" Xu Yizhou raised his own questions.

Shen Mian's gaze quickly swept over him: "After the dust has been stepped on or wiped by others, although it is also dust, the density of that mark is different from that of the dust in other places. In the same environment, the dust covered later is relatively loose, and it is easier to be blown away by the air flow in the natural environment. Of course, it's all dust, so the difference isn't particularly noticeable. ”

People who also know how to use this technique to detect smoke traces......

"But is this bookshelf really movable? Could it be that our ...... "is thinking too much?"

Qiao Jiaying asked in a low voice, not daring to think that the room he had lived in for so many days was actually like no door that was always open to the outside world.

I saw You Nanxing groping around on the bookshelf, and finally found a small protrusion behind a book on the top floor. With a hard hook of fingers, I heard a "click", and the bookshelf that was originally close to the wall popped out slightly by one centimeter.

He pushed tentatively, and as the bookshelf moved, several people managed to see the situation on the other side of the wall through the open bookshelf.

It was the house where Qiao Jiaying lived before. Because Xu Yizhou and Wei Duo didn't close the door of the cabinet just now, from their point of view, the internal layout of the room was clear.

Several people glanced at each other.

"To contact Team Yin, we need to investigate the owner of the homestay, and other colleagues who are working at the same time as us also need to pay attention to this situation." You Nanxing said to the colleague in charge of liaison.

With this discovery, at least the military order made by Team Yin has room for interpretation.

In order to prove their guess, after locking down the place, they quickly went to the B&B that Shen Mian had booked before.

The little couple who lived on the opposite side of Shen Mian's room had already come here before, and carefully repeated what had happened in its original position. At the same time, they also identified the handcuffed man in the police car, confirming that he was the one who had stopped the young couple and asked them to return the same way in the direction of the staff dormitory.

At this time, the man was also brought to the door of the homestay.

In the end, when he was young, the other party's face changed instantly when he saw Shen Mian and Qiao Jiaying standing together.

Especially when he saw Shen Mian, he seemed to be able to recall the embarrassment he had been made by the light water bottle when he was escaping. Honestly, that memory...... It hurts!

In contrast, when Shen Mian saw the other party's expression, his face was a little more playful.

This guy is probably a lot more critical than she originally expected.

At least until now, his confession will play a crucial role in the whole case.

Well...... Why did he look at himself as if he had beaten him?

While Shen Mian met the other party's eyes with some resentment, he shook the bottle that still contained half a bottle of water in his hand, raised his eyebrows slightly, and a smile appeared on the corner of his mouth. The meaning is clear: Do you want to try again?

Soon, after the other party saw her movements, he quickly retracted his eyes, and the whole person became a little more honest, at least on the surface.

This made Xu Yizhou, who had been paying attention to this person, a little surprised.

How difficult this guy is He had seen it when he was at the police station, but why did this person react like this to Miss Shen?

He glanced cautiously in the direction of Shen Mian.

In this short time together, he can feel Shen Mian's specialness, but the other party doesn't seem to like him, and it doesn't seem right to say that, the two of them don't know each other after all. To be precise, it is probably that this Miss Shen seems to have an inexplicable indifference to him.

Of course, he's not so narcissistic as to think that everyone else should like him.

It's just that this person still makes him feel a little frustrated.

I don't know what I've done wrong.

Maybe it's because of this, but it makes him a little concerned about Shen Mian.

"Let's go up first." Wei Duo nodded to a few people, she and Team Yin were in charge of this side when the investigation was made, so she was the most familiar with the situation here.

After reading a few similar big characters on the wall, Qiao Jiaying felt that the impact of these words on himself seemed to be a little smaller.

Compared to the situation in the opposite room, Shen Mian stood at the door of the room where he originally lived, following the direction of the disappearing shadow outside the door when he heard Gu Haozhi's voice before.

When she was leaving, she remembered that she had noticed the corner of the stairs.

There's no bookcase like the previous one, so what's the problem?

"Sister Shen?" Qiao Jiaying stood at the door, only glanced inside and retreated.

As soon as he turned his head, he saw Shen Mian's frowning.

I don't need to dig too deep into the logic of the brain hole, my brain is probably to this extent haha!
