Question 957 (Part Two)
The things are not in the conference room, but in a warehouse at the base. When General Liu arrived with Guo Tailai and Zhao Yanyan, what he saw was a big iron cage in the warehouse.
To be exact, there is not one iron cage, but two. The inner one is propped up to a certain height and is wrapped by the outer iron cage. The iron cage is woven with iron wire, the mesh is very fine, and the inner and outer layers are equally fine. Not only that, Guo Tailai also noticed that the walls around the warehouse are actually made of metal, as are the floor and ceiling.
Whether it is an iron cage or a metal warehouse, it is all to ensure that electromagnetic waves will not be emitted and received. The principle of electrostatic shielding, high school physics and electricity knowledge, Guo Tailai understands it very well.
It is precisely because he understands the reason for being so cautious that Guo Tailai also understands the importance of the things he brought today. Guo Tailai has already become serious before seeing anything and before starting to do it.
There is a very strong and stable wooden table in the middle, and beside the table is an explosion-proof barrel that Guo Tailai knows. This is just in case, once there is a danger of explosion inside, throw things into the explosion-proof barrel in time, or there is a chance that you will not be injured. It really is like facing an enemy!
A lieutenant colonel, carrying a metal box, walked into the innermost cage. When putting down the box, Guo Tailai found that his hands were handcuffed to the box.
General Liu and the lieutenant colonel officer had a formal handover and signed a document brought by the lieutenant colonel. After General Liu signed, he walked out of the iron cage with the lieutenant colonel officer, went out to the first floor, and closed the door on the first floor to ensure that no electromagnetic signals would leak out.
"Fatty, this thing is very important. If you're not sure, you'd rather not do it, and you can't do it rashly and destroy the things inside, understand?" Outside the iron cage, General Liu told Guo Tailai who was about to enter the iron cage.
"I understand." Guo Tailai nodded: "I won't move if I'm not sure, don't worry, I know the seriousness."
General Liu, Zhao Yanyan and the lieutenant colonel were watching from outside the iron cage, while Guo Tailai walked in with a small toolbox. The procedure is the same as coming out, enter the first floor and close the door of the first floor, then open the inner door and enter.
The metal box was placed on the wooden table, the lock had been removed, and Guo Tailai easily opened the metal box. Unsurprisingly, there was a layer of smaller metal boxes inside. After opening the second layer, Guo Tailai saw a device that was slightly larger and thicker than the Oxford Dictionary.
It should be an electronic device, with a data interface and a power interface obviously on it, but apart from this interface, it is a square metal box with obvious screw holes or something, but I didn't see any fresh ones. Twist marks.
"Have you never tried to read data directly?" Guo Tailai asked curiously looking at the data and power interface.
"There is a protection device inside the hard disk, and the hardware is verified. Once the connected system is wrong, the data will be self-destructed." General Liu quickly replied from the outside: "So I dare not give power at all. The built-in battery is enough for this state. We can’t afford to wait for such a long time if it is used for several years. And it will be charged and started as soon as it is powered on, which is very troublesome.”
Obviously, there is a special hard disk inside, and I don't know what data is stored there.
The hard disk box was left unmoved in the box, Guo Tailai asked cautiously: "Is there any problem if you just move it?"
"There is no problem with normal moving." General Liu replied again: "But before the internal self-destruct device fails, it cannot be opened easily, otherwise, everything will be gone."
"Understood!" Guo Tailai nodded, put the hard disk box on the table with both hands, and then moved the box to make room.
The hard disk can’t be read by electricity at will. We can only find a way to open it, then disassemble the hard disk directly, read the data on the disk physically and then analyze it. This is the safest way.
When Guo Tailai was speaking, a large number of nanorobots had already entered through the gap in the data interface. General Liu reminded him that he could not read it at will, and Guo Tailai did not take any risks, but first checked the structure of the self-destruct device inside.
While checking, a group of nanorobots easily got into the hard disk. It can’t be read directly through the data interface, which is hard for Guo Tailai. He can directly read the magnetic media. data. Anyway, make a backup first, just in case.
The capacity of the hard disk is not large, only 2G of space. Countless nano-robots swarmed up and stored all the data on several parallel disks in less than ten seconds. Guo Tailai doesn't care what the content is, and we'll talk about it later.
"Uncle Liu, with so many layers of metal shielding nets, can this thing send out electronic signals?" Guo Tailai asked General Liu outside while watching.
"Yes." General Liu did not answer this time, but the lieutenant colonel replied: "We have checked that this hard disk will send an electronic signal irregularly. If it is intercepted, it may be possible to get the location of the hard disk. But what we are more afraid of is that the other party sends a self-destruct signal, and once this signal is received, it may start to self-destruct.”
"Then there is obviously something wrong with their design!" Guo Tailai laughed: "Shouldn't this mean that once the positioning signal is not answered, it should decisively start self-destruct within a certain period of time?"
"The overall system is designed in this way." The lieutenant colonel was also amused by Guo Tailai's words, and said with a smile: "But it is unnecessary for each component, otherwise the cost will be too high. This hard drive is also because the data in it is relatively large. It is important to have this level of protection."
"Oh, so it is." Guo Tailai can also imagine that the cost of having such a set of self-destruct devices on every important equipment is indeed very high.
"Are you sure?" General Liu couldn't help asking, seeing Guo Tailai's observations from various angles, and even gesticulating with a screwdriver, "If you're not sure, don't move around. Let’s say we still have a chance, but once we self-destruct, we will lose all chance. This thing is not easy to come by..."
"Okay!" Just when General Liu was a little worried that Guo Tailai was not sure, he started to do it, and was seriously instilling in Guo Tailai the importance of this thing that is not easy to come by, and that if it is destroyed, there is no chance, Guo Tailai was there quickly. Answered one sentence.
"Don't take it lightly!" General Liu hurriedly reminded Guo Tailai, thinking that Guo Tailai was ready to shut him up.
"I mean, it's already turned on." Guo Tailai picked up a hard drive that looked slightly different from ordinary hard drives with his left hand, and shook it towards the outside: "The hard drive has been removed, and the power supply on it has also been removed. Do you need me to take it apart?"
