As a high-end villa community, the peak community is naturally inaccessible to idle people. The security level is also quite high.

All kinds of supporting facilities are also used to the best of their ability, after all, the needs of the rich must be perfect.

Jiang Shihua held a laser pointer and pointed to the projection screen hanging on the wall.

This is a panorama of the pinnacle community. The location of the murder is marked with a big red cross on the map. The two small circles on one side are drawn at the point where the surveillance camera has lost its picture.

"It is clear that the murderer did not enter through the gate, and climbed over the wall into the summit community. Jiang Shihua uses a laser pointer to outline a straight line with three points and one stroke.

At the end of the straight line is the wall of the summit community.

Wei Hong raised his hand and said, "I remember that the walls of the peak community are very high. ”

Jiang Shihua nodded in affirmation: "This old Yu has already gone to see it, this is a photo of the wall." ”

As he spoke, Jiang Shihua played out another photo, pointed and said: "This wall is four meters five meters high, and there is a metal barbed wire at the top. Normal people cannot enter without going through tools. ”

"But obviously, this time the murderer is not an ordinary person, you look at this. Jiang Shihua switched to the next slide.

It is a piece of metal frame that has been destroyed. Originally, this was used to hold the barbed wire in place, but now it has been cut!

Liu Bashen said: "It looks like electric welding?"

Wei Hong said: "No, no, no, we shouldn't complain about Yu Bureau's ability to do things, why is it so strong......"

Jiang Shihua laughed: "Lao Yu said that he wasted his knowledge just jokingly, when he was in school at that time, Lao Yu was a top student, but he was not good at confrontation head-on." ”

Wei Hong complained: "Now he is not good at it......"

Jiang Shihua clapped his hands and said, "Okay, don't bury the old Yu." ”

This metal column is an aluminum alloy, Liu Bashen is not wrong, Lao Yu also guessed that this is the result of electric welding. However, judging from the scene, no traces of electric welding have been found at present. ”

Wei Hong hurriedly replied: "It's that high-temperature glove!"

Jiang Shihua nodded and said, "It should be the murder weapon that may exist." ”

As we all know, the melting point of aluminum is not high, and it is only necessary to melt it in an earthen furnace.

On the other hand, the melting point of a metal alloy is usually lower than that of any metal alone due to the relationship between the mixture.

Therefore, aluminum alloy has excellent results in hardness, toughness, and corrosion resistance, while also sacrificing its melting point.

Of course, a low melting point is also a good thing, at least it consumes less energy and time to make and process.

To sum up, the biggest factor in the popularity of aluminum alloy is also this.

"OK, now let's take a look at the surveillance footage from the last day. Kindness...... Let's take a look at the last hour. Jiang Shihua clapped his hands and said.

The screen unfolds and plays at ten times the speed, and everyone is focused on not missing a single detail.

Everything in the picture is black and white, and it is clear that the surveillance camera is hidden in the shadows.

After a while, the target appeared.

Jiang Shihua canceled the fast playback and changed to a normal rate playback.

A man in a hoodie, unhurried, walks through the first surveillance footage.

It didn't take long for the second surveillance footage to appear.

Still pacing unhurriedly.

Then there is the same black and white scenery.

Fast forward again, and after some time, the hooded man is back.

Returning to the normal rate, it can be seen that the hooded man is looking around there, as if looking for something.

Wei Hong opened his mouth and said, "He's looking for a monitoring point!"

As if in response to Wei Hong's words, the hooded man in the picture also found the location of the surveillance camera.

Despite facing the surveillance camera, the hooded man's face is still hidden in the shadows, and it is impossible to see the slightest detail.

I saw the hooded man raise his right hand, and in an instant, the picture went into darkness.

It appears that the surveillance camera has been attacked.

Wei Hong was shocked: "Damn, what did he do?"

No one answered.

The figure of the hooded man also appears in another picture. It was quickly found that the monitoring point was located.

The same action, just a raise of the hand, ended the picture again.

Jiang Shihua took something from under the table and handed it down for everyone to circulate and inspect.

This is the surveillance camera that Liu Ba reached out to get before. It's the damaged one.

This is a high-grade surveillance camera, with a limited monitoring range of up to 300 meters. But now it is damaged.

A smooth puncture appears on both sides of its shell.

This is a very special sign of destruction.

It is clear from the footage that the hooded man is attacking from a frontal attack.

And the place where it is attacked, only one can pass through a hole the size of an index finger.

After that, it grew bigger and bigger, until it pierced through and was a hole the size of a half-fist.

Wei Hong was confused and asked, "Team Jiang, do you have a matching weapon?"

Jiang Shihua didn't have a clue either, and shook his head: "As far as I know, none of the weapons can complete such traces. After a pause, he continued, "I'm more inclined to superpowers than weapons. ”

"Click-"

It turned out that Li Xiaotu, who was left at the scene to deal with it, came back.

"It's almost done over there, Yu Ju said that he will do the last point, let me come back first, do you have any discoveries here?" Li Xiaotu said.

Liu Bashen said helplessly: "The suspect saw it, just because he was wearing a hoodie, and he (her) didn't know anything about his (her) features." After a pause, he said, "Moreover, Brother Jiang guesses that we may have encountered high-tech criminals." ”

Li Xiaotu was surprised: "Eh, how did it become Marvel." ”

Wei Hong complained: "Yes, so we still lack an Iron Man~"

Jiang Shihua glanced at the time and said, "Forget it, let's do this first, it just so happens that the little rabbit is also back, let's eat, we will work a little overtime tonight." ”

Jiang Shihua said to Wei Hong: "You kid is blessed, let's go and take us to the restaurant you discovered, I have a treat today!"

The crowd shouted: "Long live Team Jiang (Brother Jiang)!"
