The sunset hung red on the mountains in the distance, and the sunset was like fireworks, rendering Murong Ge's glasses red.

The site is a standard duplex house, which is actually a two-story terraced house, which was built three years ago when I immigrated. The exterior looks very good, and if such a terraced house were to move back to our city, then this one unit would have to be a thousand dollars. However, judging by the signs of the depression in front of us, this is not a popular place, and as Xiao Ke explains, most of the residents who live here do not live here all year round.

Duan Yu and Qi Meng's house and Wu Ping's house are connected together, so after determining the source of the body, they immediately suspected this neighbor with a history of theft, and the suspect did not confess, so it was up to us to break through.

It can be seen that the places that can be turned over at the scene have indeed been turned upside down. Brother Murong and I still carefully wandered up and down the first and second floors of Wu Ping's house.

Although I didn't find any valuable physical evidence, my mind kept imagining possibilities.

If it was Wu Ping's crime, then the most suitable place to commit the crime should be in his own home, after all, it takes a long time to separate the two corpses, and in other places, it is easy to be exposed, and the scene needs to be cleaned afterwards, so it may have the best conditions in his own home.

If it is in Wu Ping's house, where will it be? Bathroom, kitchen, toilet? I'd seen it countless times, but I couldn't see anything out of the ordinary, and I didn't find a trace of blood, so I frowned and paced back and forth in the hall on the second floor.

Looking out of the window, the last of the afterglow had been swallowed up by the night, and the night was quiet.

If it's not in the bathroom, kitchen, or bathroom, where would it be? After all, it's two corpses!

Yes, there should be enough space for two corpses, and these three places seem to be a little cramped, and they may not necessarily be Wu Ping's first choice.

So, the living room?

I stopped and looked around at the second-floor living room, where I was pacing, and there was nothing but a few wooden sofa chairs. It's a good place to be dismembered here. However, this was just a passing thought in my head, and it would be a pipe dream without physical evidence such as bloodstains.

I went down the stairs to the first floor, where Brother Murong was wearing a big mask and holding a strong flashlight in his hand, and was lying under a desk searching.

The structure of the hall on the first floor is the same as that on the second floor, but there is a lot of furniture, and there is a coffee table in the middle, and the layout seems to be very crowded, and there are not many vacant spaces.

If the corpse is divided in such a place, it must be very difficult to clean it in the later stage, and it is inevitable that some blood stains will be left on the corners and corners of these furniture, Brother Murong attaches great importance to this living room, it seems that he may also have this consideration.

When Xiao Ke saw that we had no intention of calling it a day, he asked the comrades from the police station to buy a supper and come over.

I had a full dinner, but I wasn't hungry yet, and I didn't have any appetite at all.

I sat in the square in front of Wuping's house, watching Brother Murong eating dumplings there, knowing that he must be thinking hard, and I suddenly felt a lot of pressure in my heart.

It's not my case, why do you want to join in the fun, I thought to myself.

If you come here, you will do it, anyway, it is trapped, if this case is not solved, Xiao Ke will definitely not let us go back, I thought to myself.

The bushes next to the square looked mysterious under the cover of night, as if there was some hidden motive for killing.

Looking back at Wuping's house shrouded in the silence of the middle of the night, it really has the flavor of the murderous house in the movie, but now there are three policemen sitting in front of the "murderous mansion" who don't speak.

I looked around at the bushes that had melted into the night, and I was still thinking about how to find a breakthrough in the scene.

Suddenly, a few bright lights appeared in the bushes.

It's a firefly! Fireflies that I haven't seen in a long time! Since when my parents took me to the countryside to camp when I was a child, I have never seen this rare treasure after seeing fireflies once. The people of our city, I bet most of them haven't seen these elves.

A few fireflies moved quickly through the dark bushes, as if playing happily.

Yes, the beautiful, warm family of childhood, like these leisurely fireflies, is playing freely.

The corners of my mouth curled and I smiled.

"Su San, what are you smirking at?" Brother Murong put down the fast food box and wiped his mouth, probably because he saw me smiling inexplicably, and he was very puzzled.

I put away my smile and said, "No, I deserted." ”

"It turned out to be a desertion, I thought you had some ghost idea again." Brother Murong sighed.

"Why don't you call it a day today? Tomorrow I will go to see Duan Yu and Qi Meng's house? Xiao Ke looked left and right, and took the opportunity to interject.

Even if I returned to the hotel, I couldn't sleep, so I ignored him and continued to say to Brother Murong: "Ghost idea? I do have one. ”

At this time, my mind was full of tumbling thoughts, and the fireflies flying in the night sky just now reminded me of an important thing.

The way I wanted to speak and stopped making Brother Murong anxious, he said: "Tell me quickly, I'm going to collapse, this scene is really a hard bone, and I haven't found any good things." ”

I said slowly, "Actually, it's nothing, I brought your thing that I called a 'blood-spewing artifact' when I was about to leave." ”

As soon as Xiao Ke heard that there was an artifact, he was full of energy: "What artifact, hurry up and take a look?" ”

Brother Murong smiled awkwardly and said, "What kind of artifact, that's just one of my topics, and it will take some time to come in handy." ”

Ignoring Brother Murong's embarrassment, I said to Xiao Ke: "It is true that this artifact has not been used on the spot, but I think it is time to appear tonight, and this forensic doctor dignified to announce that tonight is the debut of the blood spraying artifact." ”

Xiao Ke saw that we didn't seem to be joking, and he was even more anxious: "This forensic doctor feels very honored to witness the debut of the blood spraying artifact tonight, let's show it off quickly!" ”

After Xiao Ke finished speaking, he looked up to the sky and laughed, I don't know if it was to release the pressure, or not to take my words so seriously.

Hearing Xiao Ke's hearty laughter, Brother Murong and I were also infected by his exaggerated laughter, so the three of them laughed wildly.

The fireflies didn't seem to have hearing, they weren't frightened by our laughter, they still looked leisurely and smuggled, flying in the night sky.

I calmed down for a moment and said to Xiao Ke, "You go and bring my big box in the trunk, and I'll tell you how amazing this blood-spewing artifact is." ”

Xiao Ke opened the trunk of the jeep, took out my large box, and carried it in front of me, I turned the combination lock a few times, and the box opened.

Inside is Murong Ge's subject product: a spray-type serum protein fluorescence display.

The basic principle is that there are protein components in the serum, and Murong Ge added fluorescein to a special reagent, and when this reagent is combined with the protein components in the serum, it will release fluorescence. That is to say, if in a dark environment, this reagent combines with the protein components in the blood stains on the ground at the scene, it will release fluorescence, so that we can very intuitively judge whether there are blood stains at the scene and the distribution of blood stains.

It was the firefly just now that urged me to show off this artifact without Brother Murong's permission.

Brother Murong said embarrassedly: "Su San, this thing is not mature yet, you dare to secretly take it out and embarrass people." ”

Brother Murong has spent three years for this research and development project, the sprayer is bought on the market, and the function is fine, but the configuration ratio of fluorescent reagents has been debugged, and the performance has been unstable, and proteins often do not release fluorescence, so they have not tried it on the spot. Before I came, I thought it was definitely to search the scene, so it was better to take it outside and try it, anyway, if it didn't work, the leaders above didn't know.

Xiao Ke said to Brother Murong: "My classmates, and there are no outsiders, just give it a try, what if it succeeds?" ”

I stood up and said, "No matter, today is the artifact's debut day." ”

Xiao Ke was the master, he should have carried the suitcase, and the three of us returned to the scene in a column.

Xiao Ke took out the equipment from the box, fiddled with the artifact left and right, and said, "Murong, how do you use this artifact?" ”

I saw Xiao Ke's strange eyes, so I smiled and said to Brother Murong: "The manual hasn't been written yet, Director Murong, can you show us in person?" ”

Brother Murong was still a little embarrassed, he temporarily mixed several bottles of reagents together, and then poured the configured reagent mixture into the sprayer, and then carried it on his back, seeing that his expression seemed to be a little embarrassed, he stood up and said: "You Su San, bring things, don't use them yourself, and you want me to use them personally, what are your intentions?" ”

I saw him carrying a big sprayer, it was just funny, and I couldn't straighten my waist with a smile: "Who told you to find such a bulky sprayer, you could have found a portable and lightweight one, there must be one on the market, you see you are a big scientist, why don't you have any artistic cells, good products also need good design, good horses also need good saddles." ”

Brother Murong shook the sprayer while spraying the nozzle on the wall and floor, these fluorescent reagents need half an hour of reaction time to bind to serum proteins, whether they can release fluorescence depends on their luck tonight.

Brother Murong carefully sprayed in the bathroom, kitchen, toilet, living room, and room everywhere without leaving dead ends, spraying the first floor and spraying the second floor, and the fog was everywhere, so we hurriedly closed the windows to prevent the reagent mist from volatilizing out of the windows, reducing the concentration of the reagent and affecting the effect. It seems that this large sprayer still has practical use, if it is designed to be hand-kneaded, it is estimated that it can only be used locally on the ground, and this whole building really needs this big guy.

After spraying the whole space, we turned off all the lights and stood in the living room on the second floor waiting for a miracle to happen.

We were all wearing gas masks, standing facing each other, but there was no light, and we couldn't see anything except the sound of each other's breathing, and if the experiment was successful, the fluorescent effect would be strong.

You can feel from the uneven breathing that everyone's hearts are in a hurry.

"Half an hour should be up." Brother Murong said in the dark night.

The entire second floor was still pitch black, the floor and walls were not visible at all, and nothing fluorescent.

"What's going on on the first floor?" It was Xiao Ke's voice.

I looked down at the staircase, and the light on the first floor seemed to be faintly flickering like a ghostly fire.
