Chapter 74 Not Simple (4)
Now these yellow markers are all highly suspicious characters, but it can basically be determined that they are the ones. After all, at this point in time, people who behave abnormally will be listed as highly suspicious by the biological modification device. However, at this point in time, as long as you don't have a brain problem, you won't come here to mess around.
As time passed, the six yellow bright spots began to rapidly approach the location of Xingmeng Jewelry Store. However, the three people in the alley closest to Xingmeng Jewelry Store directly pried open a manhole cover and entered the sewer. Once the three people fell into the sewer, the yellow bright spots turned red, proving that the biological modification device had confirmed their identities.
As for what standards the biological transformer uses to analyze and calculate, Yang Yiwai doesn't know, but he has absolute confidence in the biological transformer and won't make any mistakes. The urgent "beep" sound started ringing rapidly, and then the biological transformer directly drew several bright red lines on the three-dimensional map scanned by the mechanical mouse.
Yang Yawei immediately operated the computer to enlarge these lines. After enlargement, Yang Yawei's eyes narrowed, and it seemed that these people had not worked for one or two days. It was obvious that they had done their work in advance. The location of Xingmeng Jewelry is in Lujiazui, Pudong District, S City. This place is basically a newly built city, and all the drainage facilities are quite perfect. Unlike the old urban area's drainage renovation, the drainage pipes here can walk in parallel after entering, and several people can walk side by side.
If the motorcycle is taken down, it can even ride directly inside from the mechanical mouse's scan map. Near Xingmeng Jewelry Store, there is a main drainage pipe. These drainage pipes are not normally used, and in Pudong District, this drainage channel is used for flood control, and also has special functions, such as air defense during wartime.
These people got the construction drawings here, Yang Yiwei was not surprised, even he could easily get the construction drawings here. The Construction Planning Bureau and City Archives of S city had already adopted the latest electronic backup system, and all the construction backup drawings of the whole city were in electronic version. As long as these were hacked, it was not difficult to find the construction drawings here. Moreover, this was not a confidential drawing. And the several red lines drawn by the biological transformation instrument on the map had already appeared at a fork in the main pipe.
Because this place is not currently in use, even if someone were to make a hole from the inside, it wouldn't cause any problems. "Enlarging this area." Yang Yiwei pointed at the structure below the vault and directly opened his mouth to the auxiliary system. Just now when these people hadn't arrived, Yang Yiwei didn't dare guarantee what method the other party would use to enter, whether they would sneak into the Star Dream Jewelry store, knock some people unconscious, or use another method.
Because the mechanical mouse's scan map is a three-dimensional perspective structure, the entire map is composed of various lines. If it weren't for the auxiliary system helping out, Yang Yawei would not have been able to find what he needed from those astronomical numbers of lines. The three red bright spots quickly approached the location of the Xingmeng Jewelry Store's vault through the underground pipes.
The vault of Xing Meng is located on the fifth underground floor, roughly two floors below the parking lot. Meanwhile, three yellow bright spots from another car have already entered the interior of the building they are in. Yang Yiwei does not know how they got in, but according to the mechanical mouse scan results, there are also a considerable number of security guards inside the building.
"Are there any structurally connected places between these two buildings? Centered around this place?" Yang Yawei directly circled the vault with his finger on the map. The auxiliary system immediately enlarged the vault, shielding other areas, and the lines on the screen quickly simplified, soon a wireframe composed of only a few lines appeared on the screen, and at a glance, Yang Yawei understood.
Underneath the building, there is a small passageway that connects to the outer wall of the vault. Excluding the thickness of the steel-reinforced concrete walls of the vault itself, the middle section has a thickness of less than 30 centimeters.
"What is this official road?" The underground pipe network of an international metropolis is so complex. Those who don't see it can't imagine, even if simplified to just these lines, it's still quite complicated. "After analysis, it's fiber optic transmission pipes and backup power transmission pipes." The auxiliary system's mechanical voice rang out.
This is absolutely impassable, I don't know what they want to do with this pipe, but those diamond jewelry are not big, the problem is that the wall of Xing Meng's vault is not only a layer of alloy steel plate about 20 cm thick on the inner wall, but also ultra-high strength concrete structure outside the alloy steel plate. Ultra-high strength reinforced concrete and ordinary reinforced concrete are different, usually used in our buildings is ordinary reinforced concrete, but generally used to build some military bases and so on are ultra-high strength reinforced concrete.
To give a vivid example, the US's most powerful bunker buster bomb AOP can penetrate 60 meters of ordinary reinforced concrete structures! And hard rock is only 40 meters! While ultra-high-strength reinforced concrete is only 8 meters! From this, we can see the strength of ultra-high-strength reinforced concrete. Although commercial ultra-high-strength reinforced concrete is not as strong as military-grade, it's absolutely incomparable to ordinary reinforced concrete. Even if the vault wall is only a few meters thick, according to the mechanical mouse scan, its thickness is still over 1 meter. Even with an ordinary engineering excavator, it would take at least half an hour to break through!
However, the outer side of the vault was not protected at the time of construction, but there were seismic detectors inside the vault. When detecting vibrations exceeding 3 levels of earthquake, the closed-circuit alarm would be automatically triggered, which is an unavoidable part of the security system. They could not use mechanical or large electric drills, and even if they did, people couldn't get in, and the vibration amplitude of the drill would definitely trigger the safety mechanism inside the vault.
So explosives and the like can be ruled out, directional blasting and the like are unlikely to be used either. The remaining methods, Yang Yiwei couldn't think of, but he could guess that apart from some chemical methods or other means, it's really not possible to break through the wall. Especially since they only had two and a half hours! Yang Yiwei looked at the time, with only 3 minutes left until the Trojan horse countdown, which meant that in 3 minutes, these people would take action!
