@@ In fact, Chen Yan tapped with his fingers. In the case of turning on the hearing genetic lock, it is easy to hear whether there is an empty drum under the tile.

It's just that when you find something like reinforced bars, the sound will be easier to distinguish. You can also hear it with Liu Qingshan's ordinary listening water products.

After a while, Liu Qingshan returned, handed the short steel bars in his hand to Chen Yan, and there was one left in his hand.

The bathroom is not large.

"Chen Yan, here seems to be wrong."

There are two bricks in the middle of the southern wall of Liu Qingshan, and there are two bricks in the middle of the southern wall, and the empty sound of the loud noise.

Chen Yan also heard it clearly, but there are two bricks ...

This scope is a bit small: "It is likely that the slurry in the tile is empty, pry it open."

"good!"

Liu Qingshan is not sure if there is something in it, or the sound of simple mortar hollow, but as long as you open it, you will not know.

Slap!

The reinforcement strikes hard, the tiles are broken, and Liu Qingshan stepped forward to check it carefully. Behind the tile was the cement wall.

His face was dark, Liu Qingshan looked at Chen Yan: "The mortar has gone."

"It's okay, try something else."

The two people knocked down from the top tiles on the top of the bathroom, and found that 7 empty heart tiles were smashed away. They were all cement walls. They were all empty in the empty lapse of the mortar.

After ten minutes, all the tiles have been knocked again, but there is still no discovery.

Chen Yan also frowned at this moment: "Where can I hide it?"

The toilet in the rental house is a squat toilet. Chen Yan stood on the countertop of the squatter and searched the entire bathroom again.

At this moment, Chen Yan has turned on the visual gene lock and carefully swept every detail.

However, five minutes later, Chen Yan still did not gain any harvest.

The tile wall is strictly seamless, and there is no possibility of dark compatibility.

"Will he not put the East XZ here at all?"

"Or have already destroyed things?"

destroy?

Not here?

Chen Yan shook his head: "Wu Digui is different from ordinary murderers.

"This kind of person's psychology is completely different from the psychology of ordinary people."

Chen Yan pointed to the disc under the coffee table: "You see the disc there, there are newly released this year, and there are old discs more than ten years ago."

"However, you look at the order of the disc, some old discs are not at the bottom, and the new discs are not at the top."

"There is also the disc played in the DV machine, which is also a previous TV series."

"Even some discs can be preserved for more than ten years, and Wu Degui will destroy what has been committed?"

"As for another place to store ..."

Chen Yan still shook his head.

"Wu Degui committed a serial murder case. What he used to use, planned plan, and even the tools for crime, he will definitely put it with himself, must be a place he can see all the time."

Chen Yan said while walking out of the bathroom and looking around in the entire living room.

"It's just, where is this place?"

That is, where can it be hidden?

The whole room is so big, a living room, a bedroom and a bathroom.

Liu Qingshan also followed Chen Yan out of the bathroom and looked around Chen Yan's eyes.

Um?

Suddenly, Chen Yan was slightly mend.

At this moment, Chen Yan was just right in front of the sofa and was facing the bathroom.

Where you can see at all times ...

Chen Yan seems to have seized any key information.

In the living room, the old sofa has been used for a long time, and there is a depression in the middle position.

Chen Yan was sitting on it and was able to judge. This is where Wu Degui often sat.

Look up, look, the corner of the left hand is the TV.

From this perspective, the more comfortable posture of TV is leaning on the sofa, and the left hand is supported on the edge of the sofa.

But when Chen Yan

After sitting straight, when you look up, your eyes are facing the bathroom.

In the simple rental house, most of the bathrooms are installed with squats.

The installation of the squatter is different from the toilet.

In fact, whether it is a squat or toilet, except for the top, the internal structure is somewhat similar.

There is a S -shaped bending tube in the water.

The S -type bending tube of the toilet is inside the toilet. Because the toilet itself has a height of 40 cm to 50 cm, it can accommodate the existence of this bending tube that can prevent the inverted backward inside the toilet.

However, squats are not good.

Due to the structure, the squatrs must be at least 20 cm higher than the ground during installation.

The reason for this is to leave enough space for the bending tube of the toilet.

Therefore, in terms of space, squats are more wasteful, but the cost is cheap.

Chen Yan got up again and looked at the position of the sofa.

This sofa is relatively small, with only two people's seats. Generally speaking, the sofa will be placed in the middle of the living room. This is in line with the aesthetic thinking of most people.

However, the sofa in Wu Degui's house was placed on the left.

That is, near the window sill.

Wu Degui's room, after entering the door, there is the bathroom behind, that is, the bathroom is close to the direction of the window sill.

What makes Chen Yan wonders is why Wu Digui did not distribute the sand in the middle?

Instead, you can see the toilet when you look up.

This is not in line with the preferences of ordinary people.

Generally speaking, staying away from the toilet is right.

There is only one coffee table in Wu Degui's room, and there is no dining table, which means that he usually eats at the coffee table when he eats.

So Wu Degui looked at the toilet as soon as he had a meal?

Is this a bit strange?

Chen Yan sat on the sofa and looked at the toilet just ...

Visual gene lock open!

Um?

Soon, Chen Yan discovered something wrong.

It is facing Chen Yan's tile. The color of the edges is not different from Zhou.

It seems that it is smoother and the reflective is heavier!

Chen Yan immediately got up, bent down, squatted at the door of the toilet, picked up the steel bars at hand, and tapped the floor tiles on the side of the high platform facing the squatter.

!!

The empty sound is very clear.

Chen Yan changed his direction and knocked on other floor tiles.

!!

The sound of empty holes comes.

Liu Qingshan naturally heard something wrong, and a surprised expression on his face: "Is this empty?!"

Alas!

Now that it is discovered, it is convenient to open it.

Chen Yan just gently stretched out the edge of his floor tiles. With a little hard work, the floor tiles were removed by the whole piece.

"Flashlight!"
