Detective Training Manual

　　 "Blood!"

　　 A simple word.

　　 I don't know if the sunset light happened to shine on Chen Hao's face, or some other reason.

　　 In short, Chen Hao's eyebrows were slightly sweaty.

　　 "Blood?"

　　 "Yes, it's blood!" Zhou Yan shouted: "When the crime happened, there was a drop of blood dripping under the crack of the door! But it was wiped off."

　　 Chen Hao swallowed, "Then...what does that have to do with dust?"

"Of course it matters. There is dust everywhere here. If you wipe the blood on the ground, then the dust around must be wiped off... And in order to make the scene look less obtrusive, the murderer must not Don't make some dust again, spread it on the place where the blood stains have been wiped off!"

"..." Chen Hao seemed to be silent for a second: "Well...what's wrong! The deceased had such a large amount of blood, and a few drops splashed under the crack of the door, that's not it. Is it normal! There is also..."

　　As soon as he said this, Chen Hao was suddenly stunned, as if something was blocking his throat, and he couldn't say a word.

　　 Zhou Yan smiled: "Why didn't you say it?"

　　 "..." Chen Hao didn't answer Zhou Yan's question, but was still stunned.

"Well, I will answer for you... The reason why you don't know what to say is because... If you follow what you said, I used a big iron on the night of the crime. The son stabbed the deceased to death, so at that time, the door of the warehouse must be closed, right!"

　　 Speaking of this, Zhou Yan walked directly to the warehouse gate and closed the door: "Look, the gate of this warehouse is only a centimeter away from the ground. Then, how can blood splash directly under the gate?

　　 Even if it really splashed here, should there be blood on the door?

Even if it is a real coincidence, only a drop of blood has entered the crack of the door, and there is no blood on the door... Then according to the shape of the blood, it is easy to tell that the blood is coming. The orientation. "

　　 Speaking of this, in fact, Zhou Yan's meaning is already very clear, that is... the drop of blood under the door was splashed from a higher position.

　　 If that is the case, it can prove that the door of the warehouse was actually open when the blood was splashing!

　　 At this moment, Lin Xi was the fastest to react. She immediately yelled at the two police officers who hadn't caught up with her train of thought, "Quickly, contact the police station and let someone send [Luminol reaction light]!"

　　 Luminol reaction lamp... This thing is not just a lamp, but a suit.

　　 It is divided into three parts: [Luminol reagent] [Blood lamp] [Light barrier].

　　The most critical one is [Luminol Reagent].

　　 This thing was originally called luminol, which is a strong acid. Its reaction principle and chemical equation are not shown here, and everyone can't understand it. Anyway, you only need to know that as long as this thing comes into contact with blood, it will emit a blue light, that's enough.

　　 Moreover, this kind of response is very ‘guaranteed’, even if you dilute it with a million times the amount of water, it’s useless. Not to mention wiping with a rag, rubbing with a mop.

　　 The most terrifying thing is that this thing can act on blood that has dried up a long time ago. How long does it take for the specifics... You may not believe it. Let alone 50 years.

　　 As for the [Blood Lamp], it is actually an X-ray lamp.

　　 And the shading board, read the literal meaning, it is used to block other light.

　　 "Okay...immediately!" After a few seconds, a police officer finally reflected and rushed to the police car, which should have contacted the police station.

　　 In the next half an hour, everyone stopped talking, and the atmosphere was so subtle that it was difficult to express in words.

　　Only Lin Xi's line of sight, always scanning Chen Hao from time to time.

　　 She is sure... Chen Hao is nervous.

　　 After a while, a scream of sirens finally came over, and everyone looked at it and saw a police car rushing over.

　　 After the car stopped, a police officer got out of the car and signaled that everything was in the trunk!

　　 Speaking of it, although the police in this world are not involved in the detection of the case, they are really professional in the work they are assigned to. After three clicks, the light shield is set up, and the reagents and reactions are all prepared.

　　 In this way, Chen Hao, Zhou Yan, and Lin Xi all entered the built-up light area. As a witness to the incident, Lawyer Zou naturally followed in.

　　 It was dark... Attorney Zou turned on the blood lamp, and for an instant, the blue light reflected everyone's faces as if they had crawled out of the underworld.

　　 "Let's open it..." Lin Xi picked up the reagent and said lightly, this reagent is acidic, and it will be very troublesome if it is sprayed on human skin.

　　 Everyone got out of the way.

　　 "Bah----" There was a soft sound, and the reagent was sprayed evenly under the warehouse door.

　　 Lawyer Zou came over with the lamp.

　　 One second...

　　 Two seconds...

　　 A light spot exuding a more faint blue gradually appeared.

One! drop! blood......!

　　 A drop of blood from half a year ago, UU reading www.uukanshu. Com is clearly presented in front of everyone in this way.

　　 This drop of blood is very inconspicuous, not the size of a fingernail, but its shape is very round. Just a little bit of imagination in your mind can create a scene of this drop of blood falling from a height.

　　 This drop of blood was definitely not sewn from the side!

　　 is falling from a higher place! Then it slapped on the ground and bloomed evenly around...

　　 When the deceased died...

Gate! It's on!

　　 "Hiss——" In the light blue shaded area, Zhou Yan suddenly took a deep breath in a loud voice, and then said, "Ehhhhhhhhhhhhhhhhhhhhhhhh!!!"

　　 He roared.

　　 This is not because of panic, but a kind of release after extreme tension. It felt like waiting nervously in front of the screen before the results of the college entrance examination were published, and in the next second, I saw that I was actually named on the gold list.

　　Excited, cheerful, a suffocating breath that has been held for half a year and finally released the pleasure with this roar.

　　 The voice was really sudden, and at close range, everyone around him was shocked.

　　 Fortunately, Lawyer Zou reacted quickly and quickly took out the camera and took this important evidence.

　　 In the next second, Zhou Yan jumped up abruptly and pushed away the built-up visor.

　　 The hellish light of the orchid dissipated in an instant, and the scorching sun of the setting sun came in and pounced on Zhou Yan's face.

　　 He wanted to open his arms and embrace the sunset of this world.

　　 But his hands were awkwardly still being leaned together.

　　 But it doesn't matter anymore.

　　 "I... survived!"

　　 Zhou Yan shouted against the golden wind!
