"......" I almost couldn't help laughing, but luckily I thought of this big man's violent temper and held back.

Storm Bear said inexplicably: "Xu Chen, why is your mouth leaking?" ”

I didn't answer him, and jumped down the entrance and exit of the cellar, and only then did I dare to let out a smile. After a few seconds, I walked to the bottom of the cellar after laughing, and saw that Mary had turned on the light, crouching in front of the corner where Phoenix had imprisoned Li Ya with a magnifying glass.

When I came last night, I was controlled by Feng Qiuhuang, who had arrived at the cellar, with a gun, and then I couldn't move with Li Ya in the corner of the wall, and I was injured again. When the police arrived, there were quite a few police officers who had come down, the scene had already been trampled on, and it had been inspected by the trace experts of the Southern District Bureau, so it was really difficult for us to collect useful traces.

Mary was silent.

I went to another location to observe, and after about half an hour, we switched positions. Before I came to the corner of the wall, there were a lot of dried blood stains on the ground, and there were many footprints on the ground, and there were potholes in the wall where the chains were broken, but there was still a metal hook embedded in it with a chain, Feng Qiuhuang should have nailed five chains in the cellar before, and the metal ring attached to the front was relatively wide, and there were a few long hairs with blood stains sticking to it. It was supposed to be for the sake of the neck, but before I came, the other party untied the neck for her.

I was impatient to look at it, dazzled, in contrast, Mary was indeed better than herself, she could withstand loneliness.

So I glanced sideways at her for a few moments, and then my heart calmed down again, and I carefully examined the corner and the side.

Before she knew it, an hour had passed, and Mary suddenly asked, "Phoenix fired two shots last night?" ”

I nodded and said, "Yes." ”

"Oh......" Mary lowered her head and continued to observe the scene.

This process may be a bit boring, but it is inevitable, because the success or failure of criminals often loses in the details, and Feng Qiuhuang and Tang Xiao imprisoned Li Ya here for several days.

Fifteen minutes had passed, and Mary stood up, and I noticed that she was holding a bag of evidence, which seemed to have something in it, and I stepped forward to see that there were little black particles, smaller than sesame seeds, about twenty or sozen.

"Sister Li, what is this?" I wondered, something so small could be extracted from a cluttered cellar.

"I don't know for the time being, it could be worm eggs." Mary thoughtfully analyzed: "This should not be left by the police of the substation, nor will it be Tang Xiao and the husky, because their distribution is relatively scattered, and they must have fallen unintentionally when Phoenix Qiuhuang was walking around the cellar." And where Li Ya was imprisoned in the corner, I also found another clue. ”

I was surprised, "What clue?" ”

"The chain that imprisons Liya's neck." Mary said while pondering: "The metal round hook at the end of it, this style is relatively old, it has long been eliminated, and some parts of it are still rusty, nine times out of ten it comes from the hardware store that has been around for a long time, and the store is relatively old, and it is reluctant to abandon it, and it is still sold in the warehouse or in the store." ”

"Taught." I nodded, knowing that I had lost in experience, and if I had changed to a big sister, I would have found this clue like Mary.

"Remember, after checking the other yard, let's go to the neighborhood to see if there are any eligible stores, what if Fengqiuhuang has a relationship with the store? Or rummage through the surveillance around the store may reveal further discoveries. Mary put the bag in her pocket and stepped the steps out of the cellar.

I turned my head to look at the remaining chains and metal rings on the wall, and followed Mary to the top of the courtyard.

Storm Bear was already impatient to wait, and said, "Sister Li, you can figure it out, my butt is about to get a boil." ”

Mary smiled slightly and said, "Storm Bear, you take the bench, and we will continue to sit after changing to another yard." ”

The bear was depressed, and with a hook of his toes, the bench flew up and was at the same level as his chest, and he grabbed it with his hands, and the whole movement was as smooth as water.

After two minutes, we came to another courtyard, located in the third house next to the opposite door of the previous courtyard, which was relatively small, and there was only one house in it, where Feng Qiuhuang lived before. Because Xu Rui ordered here, Wang Da Thong of the sub-bureau did not bring anyone to investigate, and he still retained the appearance when Feng Qiuhuang left.

The door was open, and I didn't have to think about it to know that Feng Qiuhuang was forced out of the cellar by my gun at that time, and then went back to the residence to get something and left.

Mary didn't enter the house, she walked around the yard, so I followed like a little tail, after all, this kind of learning opportunity is quite rare, and I can use it for a long time to learn how to observe with both hands.

Mary opened the door of the toilet, walked in and looked at it a few times, picked up the small stick and picked up the paper bucket, she turned around and said: "Tell your boss that the police have been deployed to the anorectal departments of major hospitals to check on the recent patients, and whether there are any patients with similar characteristics to the phoenix." Although there is not much hope, now that Feng Qiuhuang has changed his face once, let's take his portrait in the ninth game and Tang Xiao's portrait now. ”

I looked and saw that there was blood in the excrement in the toilet pit, and there was paper in the paper bucket, and the time was only within a few days. This doesn't highlight Mary's level, because any police officer can analyze it. After I contacted Xu Rui, I told him about it. She and Mary continued to walk around the yard, feeling that there were no other clues, she was about to enter the door but stopped, and looked sideways at the lock on the door's nose, "The style and appearance are also very old, and the previous chain should have originated from a shop." From what I knew from the contact with him in the ninth game, Feng Qiuhuang had a habit and really liked to use old things. ”

"Hmm......" I put the new old lock in the bag and followed Mary into the room.

Next, we spent twenty minutes inspecting the room and collected three sets of fingerprints, Mary frowned slightly and said, "Feng Qiuhuang, Tang Xiao, who does the remaining one belong to?" ”

I shook my head, Feng Qiuhuang appeared last night, we don't have many clues, we only know that there is a Tang Xiao on his side, and I don't know if there are other accomplices. Then Mary and I looked around the room and noticed a small plastic kettle knocked over the floor under the head of the bed, and there was still a little water in it.

Mary crouched down and carefully picked up the small kettle, and she tentatively touched the water with her fingertips, and there was nothing out of the ordinary. I couldn't blink to see what happened to her.

At this time, Mary took out a delicate and small pH test pen and touched the liquid, and after a while, it showed that the pH value of the water was 7.8, which is a weakly alkaline water.

What is the purpose of her PH test?

I watched quietly, not disturbing Mary. She simply dipped her fingertips in the water, put it under her nose and sniffed it for a moment, then put it on the tip of her tongue and spit it it out.

She took out the thermos cup she brought with her and rinsed her mouth and said: "This is not well water or mountain spring water, Feng Qiuhuang is not boiled and is directly drunk in a small kettle, the water quality of Qingshi well water will make stomach trouble after drinking most of it, so it should be a mountain spring water with good water quality and no pollution, you tell Xu Rui again, collect all the water spring locations in Qingshi, and then test the water quality and PH value, if there is a PH value similar to the spring water in this kettle, take a sample and compare it with this water, if it is similar, then you can focus on it, Because Feng Qiuhuang may also go to fetch water to drink. ”

After I finished talking to Xu Rui, he said to do it immediately. I sealed the kettle and held it, and then there was nothing suspicious, and we said goodbye to the police officer on duty at the scene and drove out of Red Maple Lane.

We didn't go back to the police station because we still had to find a qualified hardware store, but I was not familiar with this place, so I parked the car in front of an old man who was reading a newspaper in front of my store, and I pushed the car door and said to him, "Uncle, I want to ask you something." ”

"What's the matter?" The old man's gaze did not take his eyes off the newspaper, and he read it intently.

I asked, "Is there a hardware store that has been open for a long time in this area?" ”

"Oh?" The other party put down the newspaper, thought for a moment, and said, "It seems that there is one over there." He pointed in the direction of the end of the street, "After the end, there is less than 300 meters to the east, and it has been driving for more than 20 years." ”
