"Why is cracking this lockbox an impossible task?" Leng Yun asked strangely.

The reason why he asked this was because in all the previous operations, no matter how high-tech the lockbox, Leng Yun had successfully cracked it, and it was hard for him to believe that there was still a lockbox in this world that he couldn't open.

Leng Qianqian said: "This is the TheFortress safe launched by the German company D02ttling, and it is not a new model now, but the most classic and safest model in the history of this company!" ”

Leng Yun asked, "How safe is it?" ”

Leng Qianqian said: "This safe, except for its owner, no one can open it, it has a complex electronic password device, its owner can choose the password by himself, and it will be automatically changed regularly, even the owner of the safe will not know what the password is before opening the lockbox!" ”

Leng Yun asked, "Then how did he know the password?" ”

"This lockbox company will be paired with a magnetic device, each safe can only be paired with a magnetic device, Death 4 will put this magnetic device on the lockbox, this magnetic device will prompt a keyword, and what password this keyword corresponds to, only Death 4 himself knows." Leng Qianqian said.

Leng Yun said: "In other words, Death 4 has probably set up many sets of passwords, each password corresponds to a code word, and the combination of these code words and passwords is in the mind of Death 4, right?" ”

Leng Qianqian said: "That's it! ”

Leng Yun said: "This is very tricky, no matter how powerful your hacking skills are, I'm afraid you won't be able to hack people's brains." ”

Leng Qianqian said: "This is the case. ”

Gaia said: "What about surveillance cameras? Don't we know what the password is? ”

Leng Qianqian said: "I said it, the password will be changed every time." What's more, there is no camera in the room where the lockbox is placed, let alone a camera, there is no electronic facility in that room, as long as there is an electronic facility entering that room, the alarm will be called. ”

Lin Xiu asked, "How many digits does the password consist of?" ”

Leng Qianqian said: "7 digits. ”

Lin Xiu said: "7 electronic numbers, is it a dial-type password? ”

Leng Qianqian said: "It's dial-type." ”

Lin Xiu said: "If there are no electronic devices in that room, that is, there are no fingerprint and iris recognition devices on this lockbox." ”

Leng Qianqian said: "That's it. ”

Lin Xiu said: "7-digit password, can we brute-force it, with Qianqian's computing power, this shouldn't be very difficult, right?" We can bring in a mechanical code-cracking machine, which should be able to crack the password quickly, right? ”

Leng Qianqian said: "This is simply impossible. A set of seven-digit passwords, no one can try slowly, because the alarm bell in the safe will ring through the microphone if you turn the wrong number and put it in the safe. In addition, the safe will immediately activate the electronic anti-theft device. As soon as the electronic system is activated, that room instantly turns into hell – because the temperature in the room can reach 1000 degrees Celsius in an instant! ”

Leng Yun pouted and said, "This is really tricky. ”

"If the indoor temperature reaches 1,000 degrees Celsius, won't this safe be damaged?" ”

Leng Qianqian said: "According to the information, I can say very responsibly that this safe is fireproof, waterproof, and corrosion-proof, and it is said that it cannot be destroyed with high-performance bombs." Moreover, if too much external force is used to destroy it, the self-destruct system inside this safe will be activated, and the contents of the lockbox will be damaged. ”

Gaia stuck out her tongue and said, "The person who designed this safe is really difficult. ”

Upon hearing this, Lin Xiu suddenly said, "Let's go find the designer of this safe immediately, he may have a way!" ”

Leng Qianqian sighed and said, "The designer of this lockbox is dead, and it is said that almost all of the lockboxes sold at that time are missing, it seems that Death No. 4 has been prepared." ”

Leng Yun said: "The four dimensions of the Death Reaper No. 4 are really thorough, and he has actually done things to this point!" ”

Lin Xiu thought for a moment and asked again, "What about the other than that?" What other special features does this safe have? ”

Leng Qianqian said: "There is also a timing function. ”

Lin Xiu asked: "In other words, set a time, and if you don't have this time, you won't be able to open the lockbox even if you know the password, right?" ”

Leng Qianqian said: "That's it. I knew that Aunt Lin Xiu was thinking that she could find a way to get the password first, but it didn't work, and she couldn't open the lockbox until the specified time. ”

Leng Yun said: "This Grim Reaper No. 4, he is not afraid that he will forget the password. ”

Lin Xiu said: "I'm afraid he won't forget the password, and even if he does, it probably doesn't matter." For Death Four, he would rather not be able to take out the contents of the lockbox himself than be taken by others. ”

Leng Yun suddenly said, "There is another way to open the safe. ”

Leng Qianqian smiled and said, "Father, do you want to say that you can use X-ray equipment to see through the inside of the safe, so as to obtain the password, or know what is in the lockbox?" ”

Leng Yun said in surprise: "That's it! Isn't that okay too? ”

Leng Qianqian said: "The inside of this safe uses a special process, which can prevent all ultrasonic waves and rays from penetrating the inside of the safe. ”

Lin Xiu said: "This safe must also have an accurate tracking system, no matter where we get this safe, Death Four can also find it, right?" ”

Leng Qianqian said: "That's it, and at a certain distance, the Grim Reaper IV can also remotely activate the self-destruct device of the safe, and we won't be able to get the contents of the safe at that time." ”

Leng Yun said: "What is hidden in this lockbox?" Let Death Four take such a fancy to it! ”

Lin Xiu said: "I think in addition to the secret information of the Reaper Society, it should be the Heavenly Blade of Reaper No. 2 and Reaper No. 5, right?" ”

Leng Yun nodded and said, "It should be like this." Then he said to Leng Qianqian: "Isn't this safe a weakness or shortcoming?"

Leng Qianqian said: "There are two shortcomings. The first one is that if you forget the password, this safe will be useless! ”

Leng Yun said: "This is not a shortcoming. ”

Leng Qianqian said: "There is another disadvantage, that is, due to the special structure, this lockbox cannot withstand excessive pressure, which will make the self-destruction device and magnetic device of the lockbox fail. ”

Hearing this, Leng Yun's eyes lit up!
