"Blood!"

A simple word.

I don't know if the light of the sunset happened to shine on Chen Hao's face, or something else.

In short, the corners of Chen Hao's eyebrows oozed some fine sweat slightly.

"Blood??"

"That's right, it's blood!" Zhou Yan shouted: "At the time of the crime, there was a drop of blood dripping under the crack in the door!" But it was wiped away. ”

Chen Hao swallowed: "That...... What does that have to do with dust? ”

"Of course, there is dust everywhere, and if you wipe the blood off the ground, then the dust around it must be wiped off as well...... And in order to make the scene look less obtrusive, the murderer had to get some dust and spread it on the place where the blood stains were wiped off! ”

"......" Chen Hao seemed to be silent for a second: "That...... So what! Isn't it normal for the deceased to have so much blood that a few drops spilled under the crack in the door! And then there's ......"

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 don't you say it?" ”

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

"Well, I'll answer for you...... The reason why you don't know what to say anymore is because ...... If, according to what you said, I stabbed the deceased to death with a large iron hammer on the night of the crime, then the door of the warehouse must have been closed at that time, right? ”

Speaking of this, Zhou Yan walked directly to the door of the warehouse and closed the door: "You see, the door of this warehouse is only about a centimeter gap from the ground, so how can blood splash directly below the crack in the door?"

Even if it really spilled here, there should be blood stains on that door!

Even if it was a real coincidence, only a drop of blood entered the crack in the door, and there was not a single trace of blood on the door...... Depending on the shape of the blood, it is easy to determine where the blood is flying. ”

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

If that's really the case, then it proves that the ————door of the warehouse was actually open at the time when the blood was splashing!

At this moment, Lin Xi was the fastest to react, and she immediately shouted at the two police officers on the side who had not yet followed the train of thought: "Quick, contact the police station and let someone send the [luminol reaction light] over!" ”

Luminol Reaction Lamp ...... It's not just a lamp, it's a set.

It is divided into three parts: [luminol reagent], [blood lamp] and [light isolation plate].

Among them, the most critical is [luminol reagent].

The original name of this thing was luminous ammonia, which is a strong acid, and its reaction principle and chemical equation are not listed here, and everyone can't understand it. Anyway, all you have to know is that this thing glows blue when it comes into contact with blood.

Moreover, this reaction is very 'shelf-safe', even if you dilute it with a million times more water, it is useless. Not to mention wiping it with a rag and rubbing it with a mop.

The most terrifying thing is that this thing can act on the blood stains that have long since dried up, how long exactly...... You may not believe it. Say less 50 years.

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

And the light shield, as you can see literally, is used to block other rays.

"Good....... Right away! After a few seconds, a police officer finally reacted and hurriedly rushed to the police car, which should have contacted the police station.

For the next half hour, everyone stopped talking, and the atmosphere was so subtle that it was difficult to put into words.

Only Lin Xi's gaze always swept over Chen Hao from time to time.

She was sure...... Chen Hao was nervous.

After a while, a police alarm finally came, and everyone looked and saw a police car driving quickly.

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

Speaking of which, although the police in this world are not involved in the investigation of the case, they are really professional in their work.

In this way, Chen Hao, Zhou Yan, and Lin Xi all entered the built light area. And lawyer Zou, as a witness to the incident, naturally followed.

It's pitch black...... Lawyer Zou turned on the blood lamp, and in an instant, the blue light reflected everyone's Lian as if they had crawled out of the underworld.

"Get out of the way...... Lin Xi picked up the reagent and said lightly, this reagent is acidic, and if it is sprayed on people's skin, it will be very troublesome.

The crowd stepped aside.

————There was a soft sound, and the reagent was evenly sprayed directly below the warehouse door.

Lawyer Zou came over with a lamp.

One second......

Two seconds......

A fleck of light that radiated an even more faint blue color gradually appeared.

One! Drip! Blood......!!

A drop of blood from half a year ago was clearly presented in front of everyone's eyes.

This drop of blood is inconspicuous, less than the size of a fingernail, but it is very round, and if you imagine it in your mind, you can construct the scene of this drop of blood falling from a great height.

This drop of blood definitely didn't fly from the side to the crack in the door!

It is a fall from a higher place! Then it slaps on the ground and spreads evenly in all directions......

When the deceased died......

Door! It's open!

"Hiss————" In the light blue shading area, Zhou Yan suddenly gasped in a loud voice, and then: "Ahhh———!!!h ”

He roared.

It's not a panic, it's a release after extreme tension. It felt like waiting nervously in front of the screen before the college entrance examination results were announced, and in the next second, I saw that I was actually titled on the gold list.

Excited, exhilarating, the pleasure that has been held for half a year is finally released with this roar.

This voice was really sudden, and at close range, it scared everyone around him.

Fortunately, lawyer Zou reacted quickly, quickly took out his camera, and filmed this important evidence.

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

The hellish light of Youlan dissipated in an instant, and the scorching rays of the setting sun shone in and slammed on Zhou Yan's face.

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

But the hands were still leaning together in embarrassment.

But it doesn't matter.

"I ...... Survived! ”

Zhou Yan shouted against the golden wind!
