"It can never be cracked? What does this code mean?" Munch looked at Bobo with a helpless expression. He knew every word on the screen, but when they were put together, he didn't understand them at all.
Bobo told Munch: "This is a very famous mathematical problem. A prime number is also called a prime number. It is a number that can only be divided by itself and 1." Bobo slowed down his speech so that Munch could follow the next content. .
"The number of prime numbers is infinite. There are a very small number of prime numbers that can be written in the form of 2 to the nth power minus 1, and at the same time n is also a prime number. Such prime numbers are called Mersenne primes. So far, there are only 55 were found, and the dynamic password of this memory card was apparently set based on the 56th Mersenne prime number."
Munch seemed to understand but continued to ask questions. "What does this mean?" "It means that the password is unbreakable. Even if the most advanced supercomputer is running 24 hours a day, it will take at least hundreds of years to solve it. Even if the 56th one is found Mersenne prime numbers, hundreds of millions of digits also make input impossible. The person who designed this password is a genius."
Looking at the dynamic password box that kept beating in front of him, Munch fell into deep thought, "What if it is forced to be cracked by brute force?"
"Anyone who can set such a complex password must have thought of the situation you mentioned. I guess, if nothing unexpected happens, the result should be automatic destruction." Bobo tried to find the X-03 memory card from the database Design parameters, hoping to find a breakthrough in decryption.
"What exactly does Beverly Andrew want to hide that requires such a high-security access barrier?" Munch held his forehead with both hands, gently rubbed the top of his brow bone, and continued to ask: "The progress of the physiological data association just now How's it going? Did you find anything new?"
Bobo closed the memory card page and read out Xiao Hei's behavioral statistics table. "I just checked. Only your physiological data for the past month is saved in the freshman system."
Munch was a little surprised: "So few? Isn't it right? Is it because I don't have enough storage space?" Bobo said word by word: "It's not a problem of storage space, because you are not a member." Munch looked helpless. :"All right……"
"According to recent data, when Xiao Hei exhibits abnormal behavior, your secretion of adrenaline, thyroid hormones, dopamine, etc. all increase significantly. In other words, you are very excited or nervous. But the current sample is too small. To analyze deeper connections, more data is needed. If the number of samples is enough, maybe..." Bobo stopped explaining, and the portrait composed of codes showed tangled emotions.
"What can you do? Don't be hesitant when talking." Munch saw Bobo hesitating and was a little angry. "I found that after you completed the update, human beings' bad habits have increased a lot! They have learned to hide their words. !”
"The reason why I hesitate is because it is just a guess on my part that cannot be verified, and this guess may cause harm to you..." Bobo said with a hint of self-blame in his tone.
"This violates the three principles of robots, right? It doesn't matter. If you have any ideas, just tell me. I will decide whether to adopt them or not, and I will bear the consequences." The more Bobo behaves like this, the more Monk's curiosity grows. The stronger.
"If there is enough data, the accurate secretion ratio can be obtained through analysis, and then the implant can be used to actively inject into the veins and blood vessels to dynamically adjust the physiological state in the body to achieve the basic conditions before Xiaohei's abnormal movement. Although we cannot Predict Xiao Hei's behavior, but we can proactively wake it up..." Bobo's voice became smaller and smaller. He knew the danger of this kind of experiment. Once the matching failed, Munch's life might be threatened.
Munch thought seriously for a while and replied: "There seems to be no other way at the moment. Bobo, you can try this direction first. I will give you more physiological data, but... the error tolerance rate of this experiment is not high." It’s too high.” He smiled bitterly to himself. "By the way, Bobo, there's one more thing. While I'm resting, you can try to build a model of a mechanical heart. I don't have a clue right now."
What made him smile bitterly was not only Bobo's fatally risky proposal, but also his strong sense of uncontrollability about the current situation and the future. The events that happened one after another greatly consumed his energy. Through the screen wall, looking at the empty tracks outside the city security bureau hall, my eyelids gradually became heavy and I finally fell asleep.
…
The next morning, the City Security Bureau located on Huanyu Street in the Lille District of Tozcana once again welcomed the new rising sun. The architectural shape was somewhat similar to Saturn. Under the sunlight, it reflected little spots of light around it.
The spherical main body of the City Security Bureau is half exposed above the ground and half hidden underground. The middle junction is surrounded by a star ring for transportation. The star ring is divided into three layers: upper, middle and lower, and their respective tracks run smoothly at different speeds. At an angle of 120 degrees, three virtual water droplet vehicle traffic routes are equally divided and integrated with the urban transportation system.
Calvin stood on the star ring. After passing the identification, he followed the automatic crawler to the lobby of the City Security Bureau.
The huge spherical space has a dark blue background, with many suspended spherical objects, including spherical lights, spherical screens, and spherical guidance robots of different sizes, colors and materials. All the spheres are like pearls scattered across the sky, all floating freely. In the upper half of the ground, in a weak gravity environment.
The underground half is divided into different functional areas: Armed Forces Section, Transportation Section, Special Service Section, Archives Section, Logistics Section, etc. Different administrative units have their own unique colors for easy distinction.
Standing in the waiting area of the lobby, Calvin clicked on the police badge worn on his chest. A spherical robot flew over from the sky in a semi-parabolic trajectory and asked where he wanted to go. He said: "Go to the core brain."
After verifying that the access rights matched the interviewee's time, the aperture emitted by the spherical robot turned dark purple, and the glass protective cover on the top slowly opened. A disc-shaped standing area appeared. Calvin walked in and put his hand Placed on the guardrail raised around it.
The robot flashed its signal light, flew towards the core area on the second underground floor of the City Administration, and landed in front of Bridge Payton's office door.
Calvin stepped out of the spherical robot, and the office door opened automatically. Facing the door is a giant pattern, an eagle spreading its wings, wrapping the city silhouette of Tozcana. At the bottom is a mixture of guns, cannons, aircraft and the words of the City Security Bureau.
A virtual sphere slowly rotates in the center of the room, showing the real-time operation of each space in the entire building. On the streamlined desk, there is a dynamic photo. Donnie Young and the man next to him have their arms on each other's shoulders, looking very intimate.
"How are you feeling today?" The originally rotating sphere was replaced by a virtual portrait that suddenly appeared. The man had a goatee above his lips, sunken eyes, and held a retro pipe in his hand. He was the other person in the photo. Bridget Payton is also the top administrator of the City Security Bureau.
"Didn't come again today? You can't always avoid me, right? But it doesn't matter, we can just talk like this." The appearance of the virtual figure made Calvin hesitate for a few seconds, and then said emotionally: "I tell you , Uncle Payton, ah, no, it should be called Director Payton. This is the way I want to live! I went to investigate last night, and after only chatting for less than twenty minutes, I found out that the man named Monk Bryan Guys, there are a few fishy bits.
Can you believe that I didn’t take the elevator and climbed a dozen flights of stairs! There must be something wrong with that man's bookshelf, and his purported diary! By the way, there is also his dog. I have to find out the origin of his living pet. My implant has been paired with him! And I've got his scan sample!
…
Just transfer me to the front line. Organizing evidence files is really boring. I also want to be like my dad and do what a police officer should do! Collect evidence, hunt down criminals, find out the truth..." Calvin crackled for a long time. Bridge did not interrupt him, but just smoked silently. After a while, Calvin finally stopped talking.
"Have you finished talking? Are you satisfied now?" Bridge's avatar walked to Calvin's side and stretched out his hand to put it on his shoulder, just like putting it on his father's shoulder. However, the virtual image It went straight through Calvin's body.
Bridge put the cigarette into his mouth, inhaled sharply, and then exhaled slowly. "As promised, there is only one chance to experience it. You... you should continue to work in evidence management... This job is very important. It is the basis of all justice. Temporarily transferring you to participate in the inquiry work is against the principle. This Let’s leave things as they are for now. If I have the opportunity in the future, I will consider reassigning you to another position.”
Calvin's body softened instantly, and most of the passion just now was gone. "I can do it well! Really! I can look for evidence from clues and find loopholes in lies and truth. I can really do it! I can do it as well as my father! I don't want to be called 'relying on my father's death' anymore." The one who can get a free job. Trust me for once, Uncle Payton!" Calvin said in a hoarse voice with a cry, almost pleading.
Bridge didn't speak anymore, just waved his hand, and the guidance robot waiting outside the door entered the room and took Calvin out, who was looking lonely. After the door closed, the wall with the badges parted from the left and right, and Bridge walked out. Thinking about Calvin's actions just now, he sighed softly.
Walk to the dynamic photo, pick up the photo frame, and place your left thumb on the fingerprint scanning area of the photo frame. A fragmented video then played in the center of the room. This was the last message Downey sent to Bridge before disappearing, and he had read it countless times.
The area around the image was gray and there was no other color. Donny Young was sitting on a black rock, his eyes full of exhaustion and fear. He looked much older than he looked in the photo, and his voice was urgent and trembling as he said: " As the case deepens, I have touched the corner of the dark abyss, and the forces involved in it are more complicated than we imagined. Behind this matter, it is not about a few people or a few cities, but about the entire upper realm .Through tracing, I found that there is some kind of mysterious passage between the upper domain and the lower domain. The forces of the lower domain may have penetrated...Bridge, my comrade, please promise me to keep Calvin away from all this, his life He should be carefree, safe and happy. I can't let him be swallowed by the darkness anymore. Finally, all the evidence and materials I compiled have been sent to you. If I fall...Bridge, I hope you can take it with you. Justice will continue to investigate.”
The image disappeared, Bridge's expression was solemn, and he transferred the information from the photo frame to a deeply hidden electronic file. Only he had access rights in the entire city security bureau. The name of the document is: TS-010628.
