Faced with the questioning eyes of the police, I gritted my teeth and said that there must be something up there, and I had to go up and identify it myself.

Sun Lu and I hung up on public office, the other party hesitated a little, and after two more phone calls, he finally agreed to me and Sun Tuzi to go to the roof.

After I went up, not only the police, but even Sun Tuzi showed me a suspicious look.

The top floor is flat, except for a rectangular object made of lime with asbestos tiles on top of it, and there is no side.

One of the young police officers said they had uncovered the asbestos tile and it looked like a pool of water with nothing in it.

Then he whispered to the people around him: I don't know what the purpose of building such a thing on the roof of the building.

I said, "This should have been used by the earlier people to dry in the water." ”

Sun Lu suddenly said: "I remember, when we went to Xizi's house, there was also a cement pool on the roof of his county seat. It is said that his father let him build the base, put water during the day, or when it rains, it will be full of rainwater, dry it for a day, and connect it to the pipe in the evening, and there will be hot water for washing. ”

I nodded, it was indeed the first time I had seen a similar pool in Zhang Xi's house, although it seems to be a bit of a chicken rib now, but it also shows the wisdom of people living at home at a certain time.

"You don't mean to say that there are dead bodies hidden in this cement pool, do you?" The officer looked at me suspiciously and asked.

At this time, we have learned that this person's surname is Hu, and he is a leader of the Xicheng Branch.

I shook my head, "I'm not sure, but if you smash this pool open, you should find something." ”

"Woe, is this necessary?" Sun Lu hinted to me with his eyes that this was redundant.

I whispered to him: "If Lu Zhen's mobile phone really has a video connection, it will definitely prove our innocence." But in this case, we have to have an explanation for the police. And, I had a hunch that if I missed this opportunity, I might never find the thing we were looking for again. ”

"Since you are colleagues, you should know the rules, don't talk to each other anymore!" Officer Hu warned.

He walked to the edge of the pool, squatted down and looked at it for a while, then looked back at me with a frown, and said:

"From the outside, the cement on the surface of this pool has been simply repaired, but it may not have been much older than the two of you, and the main body itself has no signs of reconstruction. What do you think will be in here? And why, what do you think is here? ”

"I was about to ask, too." Sun Lu looked at me and didn't deliberately lower his voice again, "You asked me to call the police as soon as you came up before, just because of this pool?" How do you think there's a cat here? ”

I didn't answer him, but asked Officer Hu: "The colleague you sent to Ding Xieleng's house, in addition to Ding Xileng's body, there must be other discoveries, right?" ”

"Why did you kill Ding Xianlen? Just because he snatched your bag? ”

Officer Hu also did not answer my question, but asked a rhetorical question with burning eyes.

Obviously, Ding Xianleng is indeed dead.

It has to be said that the efficiency of the police is quite high now, and in this short period of time, they have done a considerable degree of investigation.

I was robbed of my bag by Ding Xianleng, and most of it was asked by the people around me.

I know that as a suspect, the other party will never answer any questions related to my case head-on, so I can only grit my teeth and say:

"In order to get the bag back, I chased Ding Xileng to his house. There, I saw a stone coffin lid. ”

"And then?" Officer Hu asked.

I pursed my lips, "You ask the colleagues on site to measure the size of the coffin lid, if nothing else, it should be not much different from the flat size of this pool." ”

"No, I still don't understand what you mean......"

Sun Tuzi was halfway through his words, and his eyes widened suddenly, "Do you want to say that this pool is fake, and there is a coffin in it?" ”

Officer Hu got up and walked back to me, stared at me for a while, and said:

"Xu Qiu, seriously, I've heard of you and know that your identity is a bit special. But I really think it's strange, although you have seen the stone slab of Ding Xileng's house, how can you think that this cement pool is hidden and the slate...... What about the coffin with the lid fitting? Just because it's about the same size? ”

I said, "In terms of size, it should be a stone coffin, which is used to hold the coffin, and it is still different from the coffin itself." As for why I think this pool is greasy......"

I pointed to the pool, "If this pool has been abandoned for a long time, there is no need to repair it." But if you have been using it all the time, then this pool is still missing the most basic kit that can be used. ”

"What's missing?" Officer Hu was also obviously intrigued.

At this time, Sun Lu suddenly slapped his face: "I can see it, this pool has no eyes, and it has not connected the upper and lower water pipes!" ”

I nodded at Officer Hu.

Many people may not have a specific concept of this kind of "chicken-ribbed" sunbath, but as a usable pool, water storage and discharge are the most basic.

The pool on the roof of the building, although most people do not necessarily understand its original function, can be seen at a glance that this is a pool.

However, there are no holes around or below the pool to connect the pipes.

Officer Hu looked at me deeply and didn't say more, maybe the key is that it won't take too much effort to smash the ash on the surface and confirm my guess.

……

"Boss! It's really rocky here! ”

The police officer in charge of digging the cement pool reported loudly.

The speculation was confirmed, but at the same time, as suspects, Sun Tuzi and I were also ordered to leave the scene.

Just as I was reflexively climbing to the edge of the roof and trying to go down the ladder, I suddenly heard a slight "buzzing" sound.

In a relatively noisy environment, this sound is extremely difficult to detect.

But because of my special position, I happened to notice this.

My heart moved, and I hurriedly climbed up again.

"Didn't you go down?" Officer Hu was dissatisfied, "You should know the rules!" ”

"Cell phone!"

I was anxious to squat down and look left and right, "Lu Zhen has been recording with her mobile phone, and there is no her mobile phone below!" ”

Officer Hu immediately came over and searched with me.

Eventually, it was discovered that the sound of shaking was actually coming from a drainage pipe at the edge.

In retrospect, Lu Zhen should have lost her mobile phone before she fell, and the mobile phone happened to fall into the drain pipe in the corner.

Fortunately, perhaps because the old building has not been taken care of for quite some time. The upper end of the drainage pipe was blocked by plastic bags, leaves, etc., two-thirds, and Lu Zhen's mobile phone happened to be stuck in this position......
