After passing through a long corridor and passing through three security checks along the way, Bailu finally came to the main exhibition area. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The main exhibit area is preceded by a large conference hall-like area, with six passages leading to different sections, and the American Museum of Nature has a total of five sections, each of which leads to five areas: Astronomy, Minerals, Humans, Paleontology, and Modern Biology.

A huge plane diagram appeared in front of Bailu, and directly opposite the entrance was the location of Bailu's target this time, the mineral classification area.

But Bailu is not going to do it this time, but to visit, observe the terrain, she needs to draw all the topographic maps of the entire museum before she can do it, after all, she is not familiar with it here, as a gem thief, an international level thief, the most taboo is not familiar with the terrain, once you miss, there is no place to run away.

Today's time is too short, in order not to attract too much attention, Bailu first followed the flow to the astronomy exhibition area, which is the most crowded place in the Natural History Museum, and the vast universe attracts more people to humans than anything else.

Bailu walked slowly, while looking at the introduction of the natural history museum hanging on the wall, which listed all the major historical events of the American Museum of Natural History from the beginning of its establishment to the present, including many portraits and deeds of donors.

It was not too long, Bailu walked for about ten minutes, and in ten minutes, Bailu had a general understanding of some of the basic defensive measures of the museum, which can be described as well-defended.

In the short corridor, Bailu saw at least eight probes, and each probe was a high-definition probe, there were no dead ends in the corridor, if it was just a probe, Bailu was not afraid at all, but what made Bailu feel a little headache was that the corridor was densely covered with infrared sensors.

Although the sensor was not turned on, there were all kinds of pinhole-like emitters on the wall, and Bailu still discovered these things for the first time.

If you add the infrared sensor, for Bailu, it is at most a little difficult, for Bailu she can still handle this kind of difficulty, this kind of defense level Bailu has encountered many times, and every time she retreats.

What made Bailu feel desperate was that this plain-looking corridor was actually equipped with a vibration frequency sensing instrument.

The vibration frequency sensing instrument was originally used to detect earthquakes and some military use, but in the first two years, it has begun to be transferred to civilian use, and Bailu did not notice this problem at first, until he saw a team of museum security personnel walking by, and keenly found that there was a slight gap between their boots and ordinary boots, and there was an inconspicuous thin layer of iron at the sole of the shoe.

This is a simple frequency transponder, when the security personnel wear shoes walking in the passage, the transponder will respond according to the previously set frequency, and transmit the signal back to the monitoring room, and the monitoring room will judge whether there is an outsider intrusion according to the response frequency.

The reason why Bailu knew about this instrument was because of the information provided to her by the beautiful woman in red, and the mysterious beauty in red seemed to be like a prophet, and every time she gave Bailu information, it was useful information.

But what Bailu didn't know was that the instrument of the American Museum of Natural History was also just replaced three months ago, speaking of which, this matter still has a certain relationship with Lin Qing, Lin Qing successfully invaded the National Palace Museum in Taipei and the Van Gogh Art Museum last year, so that all museums in the world feel the smell of danger, and the American Museum of Natural History also immediately updated its anti-theft equipment.

As a result, the American Museum of Nature was closed for half a month for maintenance and installed the latest anti-theft equipment.

After walking out of this passage that has made Bailu feel desperate, enter the planetarium, just enter the planetarium, Bailu was shocked, on the huge vaulted roof, a universe appeared in front of Bailu's eyes, the sun was in the center of the entire roof, and several planets around it were rotating rapidly.

Immediately after, the sun became bigger and bigger, and then like an explosion, a bright light lit up, and then the surroundings fell into darkness, and slowly a small bright spot appeared, and a low male voice sounded from all around: "About 13.7 billion years ago, the universe was '''''' by a big bang"

The shocking opening mode, let Bailu fall into it, this is a magical power, fascinating, Bailu unconsciously watched for about ten minutes, until the formation of the earth slowly came back to his senses, turned his head to look around, all the people are still addicted to the wonders of the sky above their heads and can't extricate themselves.

Walking forward, the first display item that Bailu saw was a stone brought back after the successful moon landing in the United States, and it was also the first stone that human beings personally mined from the moon by hand.

Due to the artificial dome on the roof, there is no light in the entire planetarium, and the whole area flickers and brightens with the film display overhead.

Bailu walked in front of the moon stone, and the introduction of the stone was composed of pale green luminous bodies, the light was soft and not dazzling, and the composition of the font was also very clearly visible.

"This is the stone that a wealthy man in Russia wants to buy for 10 million dollars!" The white deer looked around the moon stone, this stone is very plain, the moon is full of this kind of stone, but as the first moon stone mined by human beings, it has unparalleled commemorative value.

In the 2000s, a wealthy Russian man offered $10 million to buy the stone, but it wasn't long before the stone was gifted to the American Museum of Natural History by a collector.

This plain stone, without any value, but the commemorative significance is greater than the practical significance, if before, Bailu would definitely want to take this stone away, ten million dollars is too tempting for her, but today, although she is still carefully observing this stone, but just to figure out how the booth in this museum's anti-theft facilities is anti-theft.

After looking around the booth for a long time, Bailu roughly understood the booth's defense measures and slowly walked to the next exhibit. (To be continued.) )
