After listening to Matthew. Bell's narration, Tang Feng nodded with satisfaction, and said in his heart: "Sure enough, the more educated people are, the more ideas they have."

Now the second floor is still a mess, except for a few items that have been labeled and temporarily grouped together in the corresponding small exhibition hall, most of the other prehistoric artifacts have not been completely classified.

At this time, there are not many people on the second floor to identify and distinguish these prehistoric relics, only a dozen or so people, these people are Matthew. Bell's usual friends are also fanatical archaeologists, and they are committed to digging up other people's ancestral graves

"Matthew, how's the museum's security doing?" Tang Feng is very satisfied with all the work of the museum, but this most important security work is what Tang Feng pays the most attention to, the things in this room are really valuable, just the treasure of Captain Kidd on the first floor, the most conservative estimate is worth more than two billion dollars, because some things are priceless at all, such as the Claus gold anchor chain, such as the two gold masks, such as the two golden scepters, once these things are taken out, they are all existences that can set off storms in the global archaeological community. Therefore, the security of the museum is absolutely to be the best it can be.

Matthew smiled, pointed to a middle-aged white man in a black suit who had been following him, and said, "Don, this is Kevin of Blackwater. Mr. Johnson, all the security work of our museum is handed over to Blackwater, Kevin is the museum's head of security, and it is better to let Kevin personally tell you about security matters, he is a real expert in this area. ”

Tang Feng turned around to look, only to find that this Kevin. Johnson is really a person who is not good-looking, he is even shorter than himself, this kind of figure can only be regarded as ordinary among Europeans and Americans, and his figure does not look very strong. The only thing that made Tang Feng feel that this person was not simple was his eyes, a touch of essence that appeared from time to time, which was definitely only possessed by people who belonged to the master level.

"Hey, Mr. Johnson, welcome to the Lamberton Museum, I'm Tang. You can call me Don. ”

Kevin. Johnson stretched out his hand to hold Tang Feng's hand, shook it slightly, and said: "Just call me Kevin, thank you very much for handing over the security of this museum to us Blackwater, you can rest assured, with me, your museum will be impregnable!" ”

"Haha, I like this confidence of yours! Okay Kevin, since you're so confident, I'd like to hear how you guys do it. ”

"Okay. Mr. Tang, we can talk as we go, so that you will have a more intuitive understanding of the security procedures here. ”

This time it's Kevin. Johnson took the lead, and this capable-looking man first walked to a small exhibition hall on the second floor, turned on the lights inside, patted the exterior wall and said to Tang Feng: "Mr. Tang, first of all, I have to thank you for your generous investment, which has greatly improved the overall building security of this museum. This saves us a lot of effort in our security work. I learned from the builder that the entire façade of this museum is made of reinforced concrete. The shear walls are also up to 500 millimeters thick, which is a luxury for a two-story building that is only 15 meters high. However, this luxury also provides the most favorable external protection for the entire museum, at least such a thick reinforced concrete façade, except for blasting it with high-energy explosives. I can't think of any other way to open it without alerting the security guards. Therefore, this ring of heavy facades is our first line of defense. No one in this world has ever broken through this wall without alerting the security guards! ”

Hearing Kevin say this, Tang Feng touched his chin with a smile, and said in his heart: "Such a building has invested 30 million US dollars in civil construction alone, do you really think that these 30 million US dollars are spent indiscriminately?" If $30 million wasn't enough to make such a sturdy façade. I'm going to have to sue that builder for bankruptcy. ”

In order to build this museum, Tang Feng's first consideration was security, but Tang Feng didn't understand the real security procedures, so this guy simply came to the most practical and effective method, that is, directly use money to smash out an almost impossible to break through the outer wall, at least to improve a certain amount of security protection. And the whole building, because of the presence of that huge patio, has not a single window on the outer wall, except for the four gates on the first floor and the patio on the roof, the whole building has no exit to the outside world. In other words, in order to enter the building, there is only one patio left except for the four gates on the first floor.

Kevin. Johnson walked out of the small exhibition hall, stood on the edge of the patio on the second floor, leaned on the extremely strong guardrail, pointed to the glass ceiling of the patio overhead, which was fifty meters long and eight meters wide, and said: "Mr. Tang, because this building has a solid façade, we can safely place the center of security forces on the only five exits of this building. The four gates on the first floor are easy to say, but the key is this glass ceiling that is more than 400 square meters high, which is the most important part of our security procedures. ”

Kevin took out a tablet from his satchel, walked to Tang Feng, opened it and called up a program, pointed to it and said, "Mr. Tang, this is the specific security situation about the glass zenith." The glass of this glass zenith is all made of high-strength bulletproof glass, but even so, from the eyes of us professional security personnel, this glass ceiling is full of loopholes. For example, all of the bulletproof glass is inlaid in a steel frame, and although all the screws are installed inside, if it were me, I still have several ways to remove one piece of glass without breaking it, and then the whole museum will be unguarded. Therefore, in response to this situation, we deliberately installed a pressure alarm under the glass ceiling close to the glass. ”

Kevin. Johnson said, clicked on another interface of the tablet, pointed to the dense dots on it and said: "This is the world's most advanced positive and negative pressure alarm, the size is very small, the main function is to monitor the pressure on the glass curtain wall and the inside and outside of the glass ceiling." Once the four gates are completely closed, the entire interior of the museum will actually form a small pressure difference with the outside world, which we usually do not feel, but when we reopen the door or destroy any piece of glass in the glass ceiling, we can feel it immediately, because when the door is reopened or the ceiling glass is broken, there will always be a gust of wind gushing out from the inside of the building, which is the pressure difference between the closed building and the outside world. ”

And this pressure alarm is designed for this pressure difference. Once the glass of the glass ceiling is broken, then there will be a fluctuation in air pressure, which will cause the alarm of the pressure alarm! ”

Tang Feng nodded with satisfaction, this thing doesn't look big, but it is definitely very effective, even this small pressure difference can be considered, this is definitely something that only the top security company can think of. (To be continued.) )
