The five of them first put the photos and diaries in their hands, and then rushed to the direction of Tian Nai, Tian Nai was a little tired but stretched a lazy waist with a somewhat proud expression. Pen ~ fun ~ pavilion www.biquge.info

"That's it, I'll take care of the rest."

Suddenly, Tian Nai became a little embarrassed, "Brother An, yesterday you asked County Magistrate Huang and them to prepare materials at the Civil Affairs Bureau, but we all already knew Lu Fei's address, so I still pretended to check it." ”

Xiao An scratched his head in embarrassment, not to mention that he forgot about this matter himself, but Mu Zisheng didn't mention Xu Dong's hometown at that time, and Xiao An can't be completely blamed for this.

Xiao An picked up the phone, quickly flipped through the contents, text messages, call logs, and even recordings and notes, looked at the phone and smiled.

"It seems that as we think, the probability that Xu Dong killed Lu Fei is almost 90 percent."

Xu Dong did not have the habit of writing a diary, and the notes in his mobile phone became the key.

Xiao An watched them one by one, and had a conclusion in his heart, the content of the notebook basically said that he had the idea of killing Lu Fei, and it was not surprising that Xu Dong did this kind of thing in his style.

Xiao An thought in his heart, but another suspicion came.

"Zisheng, Shi Jia, what do you think of this mobile phone?"

The two took the mobile phone together and looked at the contents inside, and they were so careful that they wrote down the time, the two paused, Shi Jia said:

"Needless to say, the name of our death detective is not blown, it is indeed as you said, now Xu Dong is the murderer of Lu Fei, and Lu Fei's case can be regarded as clear."

Xiao An smiled bitterly, if it weren't for the guidance on Fengyin Mountain, maybe Lu Fei's case would not have been Chen Xue, and Xiao An's other suspicion is that the content of this chronicle, how did the mysterious person know, Tian Nai took so long to figure it out.

There are also what are the chemicals in Lu Dong's corpse, and the more terrifying idea is whether Lu Fei also has the kind of chemicals in his body that decay quickly.

Xiao An gave a gentle look at Molly, who was clever and sat upright.

"Molly, have you found the chemicals in Xu Dong's body that cause the internal organs to decay quickly?"

The rest of the people remembered that they had said before that Xu Dong had chemicals that quickly decayed in his body.

Molly waved her hand and said slowly:

"I thought you would ask me yesterday, but I only asked today, it's very simple, it's hydrofluoric acid." Molly thought again:

"Well, today I think the decomposition of Lu Fei's corpse is also a little strange, and it seems that he has taken hydrofluoric acid before."

Xiao An frowned, the mysterious figure is to repay the depth of his people with his human ways, it seems that this Xu Dong is really not human, but with the duty of being a policeman, he has to grit his teeth in his heart.

"Lu Fei also took hydrofluoric acid before he died? Could it be that Xu Dong did this? ”

Molly nodded,

"Hydrofluoric acid, indeed!"

Mu Zisheng looked around with sharp eyes, if he wanted to say this kind of question, he was the best at answering, and wanted to fiddle with himself, he coughed softly,

"Hydrofluoric acid, an acid ,......。 among chemicals"

The people around had a gloomy face, and Tian Nai said:

"Got to the point, okay?"

Mu Zisheng smiled, and then said:

"Okay, to the point, strictly speaking, hydrofluoric acid is not too corrosive, so we didn't expect it to be hydrofluoric acid before, but although the appearance is not very corrosive, but when it reaches the internal organs, the corrosiveness is different, we also have stomach acid in the human body, acid and acid are comprehensive, acidic and acidic, so the corrosiveness becomes stronger, plus the human body is internal organs, and the internal organs are very fragile, so it decays quickly."

Xiao An listened and pondered, but there were still many questions, and he said:

"Lu Fei died two months ago, it stands to reason that if there is hydrofluoric acid in the body, then the decay is faster, why after we open the coffin, the carrion on the stomach is still like meat puree, not much decomposed by bacteria?"

Mu Zisheng snapped his fingers and said with satisfaction:

"It's still Captain Xiao's eyes that have discovered this."

Molly thought to herself, cut, so much carrion, it's strange not to find out, and besides, the head has fallen into the stomach.

Mu Zisheng continued,

"In fact, it is also this that makes our Miss Mo realize that there is also hydrofluoric acid in Lu Fei's corpse, that is, the chemicals have more or less sterilizing effects, although it causes the internal organs to decay quickly, but the bacteria that decompose the corpse are also killed, which causes the other parts to decay almost only the bones, and the internal organs are still rotten flesh."

Xiao An nodded, this was quite clear, but the other doubts and fears in his heart were stronger.

Xiao An looked at Shi Jia,

"Can you recall the details of where Xu Dong lives?"

Shi Jia nodded and began to simulate the scene in all directions.

The place where I went in was an underground factory that was like an uninhabited factory all year round, dark, without a bit of life, vigorously in the front, and she was in the back.

Going down the stairs was a corner, and it indicated the place where Xu Dong lived, if it weren't for the landlord's guidance, they might not have been able to find it, and with the glimmer of their mobile phones, they could still open the door.

Inside the glasses is a messy place, like an abandoned garbage dump.

"Stop, abandoned dump? It's been a long time since those things were placed, or something special. ”

It's messy, it's messy, but some things are there, and some things have been there for a little longer, at least two months ago.

There was a place to cook and eat, the place was a little cramped, the boy was already covered with dust, it looked like he hadn't used it for two months, and there was a trace of dirt on the table, black.

Xiao An immediately said,

"Dirt? Black, what's it? ”

"Maybe it's an overturned vinegar bottle, or soy sauce."

"Stumped? Do you remember what's on the wall directly opposite? ”

The line of sight was pulled away again, and there was an awl hanging on the wall, as if the landlord had deliberately put it up, and there was already some dust on it, but the dust was separated by a barrier, and there was a longer time to fall into the dust.

Xiao An squinted, thinking to himself, the scar, the overturned soy sauce ,......, rope?

Look around, it's messy, it's messy, there's a desk next to the bed, it's higher than the bed, there are some books messily placed on it, there's a gray notebook, pick it up and read it, I think it's important evidence, so I wrap it up.

Look to the bed.

"Wait a minute, the books on the desk are messy? What kind of books are they? ”

English, math, Chinese, but there is some dust on these books, the latest are two, physics and chemistry.

"Physics, chemistry?" This made Xiao An and Mu Zisheng stunned, and Mu Zisheng talked a lot about the force of high school on the crooked neck tree, and hydrofluoric acid was used in the corpse, as if all the ways of killing came from these two books.

The bed is very messy, very cold, no one has slept, turned over the pillow, only to find that there is a mobile phone underneath, and a few photos, put the mobile phone and photos into the bag, and then check, there are no other characteristics.

Xiao An asked:

"That's all?"

Shi Jia nodded:

"That's all."

Xiao An exhaled, and these seemed to be enough.
