Solving the case is a little bitter, but my sister is super sweet

Lin Xuan used his super vision to start the investigation in the villa.

Hasn't he already investigated it several times?

Yes.

But now, he felt that his eyes were deceived.

Or, he was deceived by a genius!

And this genius can calculate any of your thoughts.

He can also calculate that you must have investigated the villa.

So, if he uses wiretapping and monitoring.

He will hide in places that ordinary people can't imagine.

Even some old criminal investigators and some high-IQ personnel can't imagine it.

Because this genius has calculated you criminal investigators to death!

But whether it is Zhao Qiang, Lin Xuan dare not confirm it.

After all, some cases can be reversed in various ways.

Do you think you see the truth?

Don't make a fuss.

Some cases can't guess what the truth is until the end!

Lin Xuan's eyes checked the whole villa bit by bit.

Two hours later, his face turned a little blue.

Because nothing was found!

But the more he didn't find it, the bigger the problem was.

He never doubted his intuition.

It doesn't matter if you are wrong, but if you are right, that's the most fatal.

Suddenly, Lin Xuan was stunned.

If the police come to the crime scene, what should they do first?

Protect the scene!

Nothing in the scene can be destroyed, this is common sense.

Is there a possibility.

The other party knows that you dare not destroy the scene.

So those monitoring and eavesdropping methods are hidden in the place you dare not destroy?

Lin Xuan walked into the bathroom, looked at the bloody and smelly bathtub, and ordered, "Turn on the water!"

Everyone was dumbfounded and looked at him.

They couldn't figure out the taboo of destroying the scene. As a police king, why would Lin Xuan make such a mistake?

But orders are orders.

The water in the surf bathtub was quickly drained.

"Towel!"

Lin Xuan raised his hand, and the team member handed him a towel.

He began to wipe the bathtub carefully and wiped it clean.

Then, his eyes lit up.

In the bathtub, he found a 'dot' the size of a cotton swab head.

This dot seemed to be embedded in the bathtub, and its color was similar to that of the bathtub.

When the team members saw the dot, their faces changed.

After identification.

It was found that there was actually an infrared temperature sensor hidden inside the bathtub!

As long as someone enters the bathtub, this infrared temperature sensor can sense it.

And through it, a person's body temperature can also be distinguished.

For example: if a person dies, his body temperature will drop rapidly!

At the same time, this infrared temperature sensor has a remote data transmission function.

It will send out all the 'detected' data.

"Good trick!" Lin Xuan was amused.

Through this method, the murderer can confirm whether someone has entered the bathtub and whether the person who entered the bathtub is dead.

Is that right?

Just say, who can think of such a trick?

Even the old criminal detective can't think of it, right?

Then.

Lin Xuan found another abnormality.

There is something wrong with the bathroom glass in the villa.

Many people may have seen how to identify one-way perspective mirrors on the Internet?

For example, put your finger on the mirror and investigate its image.

In a traditional mirror, the fingernail is not directly connected to the image.

If it is a one-way perspective mirror, the fingernail will be connected.

But Lin Xuan and other team members never thought of it.

Someone actually made a special one-way perspective mirror.

The "perspective point" of this mirror is only the size of a coin.

The rest of the place is normal.

How can you find it? How can you find it?

If Lin Xuan hadn't thought of a genius and noticed something wrong.

Maybe even he would be fooled.

When the mirror was broken.

A pinhole camera was hidden inside.

And this pinhole camera also has the function of remote data transmission.

Haha... Lin Xuan sneered.

Okay, you are so cruel!

Then after a carpet-style... destruction.

Lin Xuan and his team members found a total of nine cameras, six listening devices, and four infrared temperature sensors.

All hidden in unexpected places.

All places that criminal investigators can't easily destroy.

Lin Xuan and others can be said to have opened their eyes.

The murderer's layout was so exquisite and his methods were so superb that they had never seen it before.

Not only was he smart, but he also calculated people's hearts to the limit.

Lin Xuan was also 90% sure that the murderer might really be Zhao Qiang.

Because only such a genius.

It was possible to calculate him, the police king, and his team members to such an extent.

And even if you found these things now, it would still be useless.

You can't find the murderer through these things.

You can only confirm that there is such a murderer.

That's all.

It's like you bought a pie and took several bites before you got the filling.

But how much filling is in this pie is still unknown.

There is another possibility that there is only one bite of filling in this pie.

The rest is all pie!

This is the opponent's method.

Is it powerful?

Whether it is Lin Xuan or the team members.

Their faces became more solemn than ever.

Because in their opinion, the opponent's method is more than powerful.

But it was terrifying!

Suddenly.

Lin Xuan looked at the cameras, listening devices, and infrared temperature sensors.

He asked, "Are you watching us now?"

In an instant.

The scalps of the team members almost exploded because of his words.

They felt creepy and stared at those things.

No way?

In fact, even Lin Xuan himself was doubting whether his guess was wrong.

Because he did not feel any feeling of being "spying".

And the opponent he faced this time was not an ordinary person.

You have no idea what other means he has.

Who knew that at this moment.

"Hehe..."

A sneer that could not distinguish between men and women sounded in the living room of the villa.

That weird laughter seemed to echo in your ears.

The air became gloomy and terrifying, making people shudder.

In an instant.

Lin Xuan stood in front of the coffee table.

Because the sound came from the coffee table.

When Lin Xuan waved the cards on the coffee table.

But he did not find anything abnormal.

But Lin Xuan's eyes were fixed on the marble tabletop.

He raised his hand and punched.

Boom!

The marble tabletop was shattered by his punch.

An object appeared in the broken marble.

After identification.

It was a 'physical conduction' speaker.

Many people may have heard of this kind of speaker for the first time.

However, many people have seen a kind of headphones.

Bone conduction headphones.

Their principles are very similar, both of which are a way of sound conduction.

That is, converting sound into mechanical vibrations of different frequencies, transmitting sound waves through object sensing.

Facts once again proved that Lin Xuan guessed right.

He also stepped on the murderer's tail.

What happens if a cat's tail is stepped on?

It will scratch people!
