Glancing at the time on my wrist, one o'clock in the morning.

Almost, thirty minutes to go. Li Zimu looked at the showcase in front of him, which was the oracle showcase he had been staring at for the past few days.

At this time, the tortoise shell in the far corner of the display case was still lying there quietly.

Li Zimu thought carefully for a while, and then he was ready to start working.

The glass of this display cabinet is the key, and if you want to destroy it without alarming the alarm device in the glass interlayer, the two are contradictory and troublesome.

Museum display glass looks no different from ordinary architectural glass, but it is very different.

The former is functionally diverse, and the structure is also much more complex than architectural glass. It can not only effectively isolate ultraviolet rays but also prevent cultural relics from being damaged.

And from a safety point of view, it has the functions of high hardness, anti-self-explosion and anti-intrusion, that is to say, even if you use a hammer to smash, it will not be smashed for a while, and this thing will automatically alarm if it is shaken.

However, Li Zimu was naturally prepared, and pasted a palm-sized metal object directly on the display case. Immediately, a faint red light came from the side of the thing.

Fortunately, this is the innermost area near the exhibition hall, so the monitoring is much smaller, and its value is not as valuable as the Zhang Daqian showcase they passed by before, so it is not like the exhibition area over there with a lot of advanced monitoring equipment.

Qingyang Museum is a relatively old facility, there are fewer stealers this year, these equipment can be used or will be used, but presumably after tonight, the facilities here will all be updated......

This small round metal disc is a kind of signal jammer, which is much more advanced than the kind of signal jammer that the lower nine streamers use to steal things from other people's cars.

This thing can emit an electric current that can effectively disrupt the alarm system in the glass laminated, rendering it useless.

Ordinary glass is a bad conductor and cannot conduct electricity under normal circumstances, and the glass of this museum showcase is different, but it is also a kind of tempered glass, which can conduct electricity, so the jammer can play its role normally.

The same thermite spray gun, the plum wood is skillfully taken out and ignited, the magnesium strip can withstand a very high temperature, even if there is thermite attached to the surface and burned, it will still not melt.

The melting range of tempered glass is only 800 degrees Celsius, the glass of the museum display case, no matter what metal material it adds to it, most of its material is still glass, so the melting range will not be much higher.

Compared to the two, the magnesium bar is like a hard needle piercing into a thick piece of cloth, although there is an obstacle, but there is still no problem, and it is even easier than when the roof door was melted before.

After a while, a large round hole appeared in the glass of this display case, and as for why he had to draw a regular circle, it was just out of Li Zimu's obsessive-compulsive disorder......

Unexpectedly, there was no alarm, Li Zimu gently took off the thick transparent glass and put it aside, without rushing to reach out and take out the tortoise shell inside.

It's not that he has to wait for a while, but he's looking at the base of this tortoiseshell.

Logically speaking, the facilities of the Qingyang Museum are old, and this tortoiseshell is not a very valuable thing, so it should not be installed with anti-theft devices.

However, Li Zimu didn't dare to make a conclusion, and he still had to be careful in everything.

The glass display cabinet is the last line of defense, but some can only be the bottom two lines of defense, because the base of some cultural relics is also installed with an alarm system.

This kind of alarm system is generally only found in places such as museums, where the relics are placed on a pedestal with an anti-movement alarm device underneath.

Its principle is very simple, in popular terms, how heavy the cultural relics are, what are the specific parameters of the location, these two data are in the record of this alarm device.

Once the cultural relics are moved, or the weight suddenly decreases or increases, it will trigger its alarm device, and then the alarm system will send out an alarm, and the people in the center on duty will immediately come to check when they receive the message, and at the same time, the telephone line connected to the device will automatically call the police.

So Li Zimu didn't dare to move it rashly, because he was afraid that there would be an alarm device on its base, although the possibility was five or five, but he still didn't want to take this risk.

It's just that this base is an insulator, and the current jammer can't produce a role, so the best way is to disarm the alarm system of this thing.

Quickly taking out a metal object found with a thumb, Li Zimu pressed the button, and after two seconds, he took out a small tablet.

The appearance is no different from the average tablet.,But the effect is different.,Insert the little thing just now into the small opening on the side of this tablet.,Then,The specific data of this tortoise shell appeared on the screen.。

The length is 162.62 mm, the width is 94.34 mm, and the height is 21.44 mm, and the weight can be calculated by the analysis of the material to be 363.75 grams, and the error will not be higher than 0.02 grams.

Today's criminal actions can be roughly divided into several types, one of which is high-tech crime, but it is a contest between electronic products on both sides.

The products used in plum wood are high-end products in the world, and the scientific and technological content is much higher than the testing equipment of the Qingyang Museum, which is quite a feeling of cannon hitting mosquitoes......

Successfully hacked the detector of this base, a series of data appeared on the screen of the tablet, Li Zimu still knows a little about computer programs, although it is not as good as those genius hackers, but tampering with the data of some small things, this kind of thing is still easy to catch.

He had already investigated the model of this showcase in advance, so he knew exactly where the device was located and what equipment was used.

After waiting for the progress bar on the computer screen to reach 100%, Li Zimu unhurriedly took out the tortoise shell in the display case.

The thing was not very heavy, Li Zimu just glanced at it slightly, and after confirming that it was this again, he wrapped it up and put it in his backpack to get ready to slip away.

After thinking about it, I took a tortoise shell and put it in, even if it was discovered at that time, even if some people investigated the origin of the lost cultural relics, it would play a role in confusion......

"Meow!"

"What's wrong?" Li Zimu had just packed up his things when the sound of pudding sounded in his head.

"Brother Zimu, it's the last one again!
