The smell of two people, why say a body odor?

Because these two people have a close relationship, they have the smell of each other.

After Xiao Yu felt that he had grown up and was no longer a younger brother who used his sister to support him.

Not only has it opened up a new world, but it has also filled in a lot of knowledge blind spots and knows a lot of smells.

Raising his head, Xiao Yu looked at the monitoring on the door of the building, as well as the monitoring in the factory area.

Around!

Two of them focused their eyes on themselves.

Hehe…… Xiao Yu sneered silently and prepared to reach out and push the door.

Suddenly, his palm stopped a centimeter outside the door of the metal building.

Xiao Yu closed his hand, flipped his palm, and leaned his back against the gate one centimeter away.

What does this do?

He was observing the hairs on the back of his hands.

Watch the tiny hairs dangle.

There is electricity on the door, and the voltage is not weak!

You guys are real dogs… Xiao Yu closed his hand and raised his leg.

Boom!

The door of the building was kicked open by Xiao Yu’s incomparably violent kick and slapped on the ground.

You can see the door frame of the gate, and there is an instant spark.

Have you ever seen an electric ‘line of fire’ hitting a spark of metal?

Wires come into contact with other conductors, and objects can form loops and ignite!

Suppose Xiao Yu had just directly touched the door with his hand, and he had already been electrocuted.

Simple electric shock doesn’t kill you, right?

So when you are electrocuted, what if there is a pool of water under your feet?

Xiao Yu looked at the ground, his eyes cold and piercing.

If you don’t die, you will be ripe in two parts, just like being skinned by someone!

Xiao Yu stepped into the building.

Because no one cleans it all year round, its inside is very dirty.

Just because it was dirty, there was dust everywhere, and you could see that there were a lot of footprints on the ground.

Two kinds of footprints, touring shoes and high heels.

Following the corridor and following the footprints, Xiao Yu walked towards the stairs.

Just two steps away, a smell came into his nose and mouth.

Very fresh smell!

Why is there a fresh smell in the building?

Ozone!

Trace amounts of ozone have little effect on the human body, and a small amount will make people feel comfortable, such as fresh air after a thunderstorm.

But at this time, the ozone content in the air, the ‘concentration’ is obviously wrong.

To be called ‘concentration’, you think about what kind of state the air will take.

Xiao Yu thought that in this smart home appliance serial murder case, two victims died due to harmful gas poisoning of air conditioners.

Can air conditioners also transmit harmful gases?

Indeed, the air conditioner has a air supply function, which can flush the outdoor air into the room.

Nowadays, many intelligent air conditioners have increased the air chlorination function on this air supply function.

Not only can you add ‘negative ions’ to the air, but also ‘ozone’.

But……

Xiao Yu looked up and looked at an air purifier placed near the walking platform above.

Air purifiers can also produce ‘negative ions’ and ‘ozone’.

What are the so-called harmful gases?

It’s ozone and negative ions!

When the concentration of these two different substances is too high, being in this high concentration environment for a long time will cause human neurotoxicity.

Neurotoxins don’t need to be explained, right?

Causes the striated muscles to not contract, which quickly leads to respiratory paralysis and suffocation to death.

Among the millions of toxins, nerve poisons are always the king.

The solution of the possum… Open!

Xiao Yu stared at the purifier with a cold face.

Let’s say a few ordinary people, such as the second group of members, they come in.

It didn’t feel like they were going to die for ten minutes, and they didn’t even know how to die.

First the gate was electrified, and now it was the purifier that released the poison.

This killing method is a bit of a riot!

Syllable!

Xiao Yu, who walked up to the slow walking platform, kicked off the power plug of the air purifier and walked to the second floor.

When I got to the second floor, I wrinkled my nose a few times.

The human odor in the air is weak and dispensable.

No one…… Xiao Yu continued to walk like the third floor.

On the slow walking platform, a purifier discharging high concentrations of ozone and negative ions is also placed.

This is not just a dog, this is definitely a dog king!

Xiao Yu was also very bitter in the face of this kind of criminal.

Kicking off the purifier plug again, turning off the purifier, Xiao Yu came to the third floor.

The result was just stepping on the third floor.

A sweeping robot slowly and leisurely passed by.

Xiao Yu: …

He stared at the sweeping machine.

Is this stuff dangerous?

Generally not, however, it has a spy feature!

Ripping the calves? How can this thing have a spy function?

Because it is not only smart, but also has a camera function, it can become a ‘surveillance’!

You’re looking at me… Xiao Yu raised his thighs and fell.

Boom!

The sweeping robot was shattered by his foot.

Between the sniffles, there is a ‘rich’ human body odor.

It is explained that half an hour ago, there were still people walking through the corridor on the third floor.

Xiao Yu walked to the corridor on the third floor and walked step by step.

Until the footsteps stopped outside a similar bathroom.

There was no door, but there was a strange noise inside.

Xiao Yu stepped in and took a few looks.

It is indeed a bathroom, which not only has two toilets, but also a bathroom.

The noise is from the electric water heater on the wall of the bathing room.

Well?

Xiao Yu stared dead-eyed at a display on the water heater.

It was found that there was no normal display on it, and it was all something like ‘garbled code’.

In addition, it was also found that the water heater not only emitted a ‘purring’ sound.

The whole water heater actually has a slight shaking.

Garbled? Strange noise? Dithering?

Suddenly…… A life-and-death crisis rose from Xiao Yu’s heart.

Moment.

There was a muffled noise beneath his feet.

Pounce out of the bathroom like a leopard.

That’s when it happened.

Rumble!

Explosions sounded.

The water heater in the bathroom exploded in an instant, and the white mist and hot water splashed with the exploding fragments.

That kind of power is almost comparable to the explosion of an ordinary grenade!

Hiding outside the bathroom, looking at the debris and hot water spraying out from inside the door, The corners of Xiao Yu’s mouth twitched.

Can you believe it?

This exaggerated explosion is what the water apparatus we use in our daily life looks after it explodes!

Don’t talk about all kinds of protection, if it’s a smart device.

Intelligent management function once damaged, various protections give you dry circuit breaks…

Xiao Yu took a deep breath, walked through the bathroom, and walked toward the end of the corridor until he stopped in front of a door.

Looked at the doorknob, twisted, and pushed the door in.

Hey…… Xiao Yu was surprised.

He saw a woman.

At this time, the woman was tied hands and feet and closed her mouth.

When she saw Xiao Yu, she writhed with a pleading face, as if she was asking for help.

The woman is a suspect in this case, Zhuo Wan!
