Chapter 14 Chapter 14

"According to your instructions, Chief," Smith began, "we have been following Mr. Ensei Tomoka. The murder went well. But then something went wrong, and a group of passers-by came, and Herohot didn't even Get something like that." "Where is Holohot now?" Smith looked back over his shoulder and said, "He's with us, sir." Fontaine breathed a sigh of relief.The camera pans across the cabin, revealing two limp bodies against the rear wall of the car. "Hello Holt is dead?" asked the director. "Yes, sir." There was a scream, "Third firewall attacked!" There was a commotion in the room.

On the screen ahead, an agent wearing a signal switcher stretches out his arms in vain. "Sir, no markers were found." "Damn it!" Fontaine couldn't control his anger, "It should be there! Keep looking!" Fontaine made a bet, but he lost.Jebba is on the field.He scanned his army of programmers and ordered: "Cut off the backup circuit! Start turning off the power! Immediately!" "It's too late!" Cao Zhi shouted. "It takes half an hour to turn off the power! It's too late!" Jebba opened his mouth to answer when a scream of pain from the back of the room interrupted him.Susan jumped up from her chair.She stared at David Baker who was frozen on the screen with a pale face, and saw that he was motionless and covered in blood.She stumbled towards the picture and stretched out her hands. "David... oh, Davy... how could they—"

Fontaine asked in bewilderment, "Do you know this man?" David Baker's mind went blank.I'm dying.He heard a voice in the distance... "David." A voice called to him. Someone pulled him up.Agent Smith sat Baker in a chair, facing the screen. "Y-yes," Susan stammered, "I saw the message that was sent, saying..." Smith nodded. "Hello Hot's wishful thinking was too early." "But that blood..." "Just a flesh wound, we shot him with a stun pistol. Don't worry, ma'am," Smith reassured, "he'll be all right."

Baker stared at the TV screen in front of him.There Susan was gazing up at herself. "Susan? Susan, I have something to ask you." The echo from the microphone made everyone stop what they were doing. "Susan Fletcher," the voice echoed, "will you marry me?" The room suddenly fell silent. "Day--David . . . you asked me, five months ago. I said I would." "I know." He said with a smile, "but this time I have a ring." "Read it, Monsieur Baker!" Fontaine ordered. "Read it carefully!" Jerba said in a commanding tone. "It's better to be successful once. Usually one wrong input, and the program will speed up the loop. Two wrong, and you can never get in. It's all over."

Baker nodded and calmly read the mark engraved on the ring: "Q...U...I...S...Space...C..." "Space?" Jeba stopped typing and asked, "There is a space?" Baker checked the ring and said, "Yes, there are several spaces." "That's weird. Passwords never have spaces." Brinkerhoff shouted: "This is not a code, what could it be? Who the hell carved a bunch of random letters on the ring?" "Ah... the letters engraved on this ring are not random." Baker explained, "Actually, this is Latin. It reads as Quiscus-todietipsossustodies. The translation roughly means——"

"Who will monitor these monitors!" Susan took David's words and said. "This sentence comes from a satirical poem by Juvenal. Who will monitor these monitors? When we monitor the world, who will monitor the National Security Agency? This is Yuga's favorite saying!" "Just omit the space," Brinkerhoff yelled, "and type!" Fontaine turned to Susan and asked, "What do you think, Ms. Fletcher?" "I don't think it's a password." Fontaine took a long breath, and his dark eyes shot a searching light towards Susan's eyes. "If it wasn't the code, why did Ensei Yuka give it away? If he knew we murdered him—don't you think he wants to throw away the ring to punish us?"

Another voice interrupted their conversation: "Ah... Director?" It was Agent Coriander's voice. "I'm not so sure that Mr. Ensei Tomoka knew he was murdered." "Agent Smith, what do you think?" "Helohot uses non-diffusion damage bullets. There is no sound when the shot is fired. There will be no bleeding after hitting. Mr. Yuga only felt a violent heartbeat. It seems that he did not associate this feeling with the shooter. ’” Smith added, “He didn’t even look for the guy who attacked him. When a guy gets shot, he always goes for the attacker. It’s instinct.”

Fontaine was puzzled for a moment. "You mean Ensei Yuka didn't go to Herohot?" "Yes, sir. We have video, if you'd like—" A technician yelled, "The worm is coming!" "Let's forget about the video," Brinkerhoff asserted, "let's get this done first!" Jeba sighed and said calmly: "Director, if we make a mistake..." "And," Susan interrupted, "if Ensei Yuka doesn't suspect that we murdered him, then we have a few questions to answer." Fontaine was silent for a long time, then sighed heavily and said, "Okay, let's play the video."

An open square in the park appears in the middle of the screen.At one end of the square is Seville City Hall.In front is a forest.The park was empty. Smith began to explain. "This is the scene taken from the van, about 50 meters away from the kill zone. Yuka is walking from the right, and Herohot is hiding in the woods on the left." At this time, Ensei Yuka appeared on the screen.He shaded the sun with his hands on his forehead and looked up at the roof of the huge city hall. "Here it is," Smith reminded everyone. "Hello Hot fired the first bullet." On the left side of the screen, a ray of light is reflected from behind the trees.A moment later, Yuga clutched her chest tightly, shaking suddenly.

Smith calmly explained: "Yoga stopped his heartbeat immediately. His eyes were looking down, looking at himself. If Yuka suspected that it was murder, he would instinctively look around carefully. However, he did not Didn't do that." Yuka fell to the ground.A man's figure appeared on the screen.The man, wearing wire-rimmed glasses, walked towards Yuka.Suddenly, an old man rushed out from the nearby courtyard and knelt down beside Yuka.After a while, two more people came out—a fat man and a red-haired woman.Hulohot retreated into the woods. "The rings are changing hands here."

Panting heavily, Yuga desperately raised his left hand.The camera locks on to the three misshapen fingers; one of them wears a gold ring.The old man stood up suddenly and ran away.Yuka looked weaker and weaker, held the ring up in front of the man, nodded slightly to the man, and then dropped his arm weakly.A police car shows up.The woman pulled the man up and fled in a hurry. The camera locked on Yuga, his heart stopped beating, and the ring on his hand was gone. "Here's the proof," said Fontaine decisively, "that Ensei Yuka wants the ring taken away—so we can never find the combination." "But, Chief," argued Susan, "if Yuka didn't know he was murdered, why did he give up the code?" "If anyone here can point out anything more like a cipher than this ring, I'm all ears." Nobody said anything. "Yuka won't throw away that ring for no reason. I've made up my mind. Type the letters on the ring. Now." There is no better choice.They will be too late.Baker read the letters, and Jerba typed them into the computer, stripping out all the spaces.The screen shows: QUISCUSTODIETIPSOSCUSTODES "Knock," Fontaine ordered.Jebba pressed the "Enter key". "The worm is speeding up the loop!" Kusashi yelled from the back of the room, "The password was entered incorrectly!" An error message is displayed on the screen: Illegal input.Numbers only. The third firewall crashed, and six black lines appeared on the screen.The number of hackers attacking the defense line will increase exponentially from now on. Cao Zhi rushed to the podium with a new printout. "I've found something, sir!" she exclaimed excitedly. "Orphan lines in the worm! Alpha groupings. Everywhere!" "Orphaned lines" refer to additional lines written while programming.These additional lines have no effect on the program's goals.It is usually deleted during the final debugging and compilation of the program. Susan narrowed her eyes. "The worm program that Yuka didn't finish writing actually attacked us? Yuka is a perfectionist. He will never allow any loopholes in his program." "There are a lot of orphaned rows here!" Kusashi yelled. "Look!" Susan nodded.Sure enough, almost every twenty lines, this program has four separate characters. "Four-digit alpha blocks. These are definitely not part of the program. Many encryptions use four-digit blocks. This could be a cipher." Susan typed out all the groups. PFEESESNRETMMFHAIRWEOOIGMEENNRMAENETSHASDCNSIIAAIEERBRNKFBLELODI "Yoga left us a clue! He's taunting us to try and find the code in time. He's hinting and we don't get it!" "It's absurd," Jeba snapped. "Youka only pointed us to one path—exposing the TRANSLTR. But we ruined our chance." "I can only agree with him," Fontaine said. "I don't think it would be possible for Yuka to tip someone his password and risk letting us get away." Susan can remember how Yuka gave them hints through NDKOTA.She stared up at the letters on the screen, wondering if this might be another trick by Tomoka Ensei. "The Tunnel Program Module is failing immediately!" a technician yelled. On the schematic diagram, black lines rushed in, attacking the remaining two lines of defense. Baker has been sitting there quietly, watching the picture presented on the monitor screen. "Susan, are those characters sixteen quadlets?" "Yes, it's sixteen groups." "Remove the blank space." Baker said firmly. Susan hesitated for a moment, then nodded at Kusashi.Kusanagi quickly removes spaces.The result is still as puzzling as the original. PFEESESNRETEMMFHAIRWEOOIGMEENNRMAENETSHASDCNSIAAIEERBRNKFBLELODI Jebba yelled, "Have you played enough! Game over! The worm is looping at double speed! We only have about eight minutes! We're looking for numbers, not a long string of incomplete letters !" "Four times sixteen," said David quietly, "do the math, Susan." Susan looked at David on the screen.Calculation results? "Sixty-four, what's the matter?" David leans close to the camera, his face filling the frame. "Sixty-four letters..." Susan nodded and said, "Yes, but this is—" She froze for a moment. "Oh my! David, you're a genius!" In order to intercept intelligence from the network, the National Security Agency of the United States spent huge sums of money to build a machine that can crack all passwords --- TRANSLTR.This supercomputer has thwarted the plots of countless terrorists, but it can also intercept ordinary people's emails.Is the world devoid of privacy and secrets?Please follow Dan Brown, the king of American suspense novels, into the puzzle of "digital castle" and experience a thrilling high-tech confrontation in the information age—— "Eight rows and eight columns!" Susan exclaimed excitedly. "Sixty-four letters! That's a perfect square!" The letters on the screen are arranged in eight rows and eight columns: PFEESESNRETMPFHAIRWEOOIGMEENNRMAENETSHASDCNSIIAAIEERBRNK FBLELODI "Ms. Fletcher," Fontaine asked, "you explain." Susan stared at the group of letters and burst into laughter: "David, I'm so surprised!" David blinked at Susan on the monitor screen, and said, "Julius Caesar strikes again." Mickey asked in confusion, "What are you talking about?" "This is Caesar's phalanx," said Susan with a beaming smile. "Tomoka Ensei sent us a letter. Rearrange from top to bottom! Look vertically! Julius Caesar used this way to transmit the password! The number of letters he uses is always a perfect square number!" "It's ready!" Cao Zhi shouted.All looked at the line of rearranged letters on the projection wall. PRIMEDIFERENCEBETWEENELEMENTSRESOPNSIBLEFORHIROSHIMAANDANAGASAKI "Insert a space," Susan ordered, "and we shall solve this mystery." "The last line of defense is under attack!" In the schematic diagram, the penetrating black line devours the last line of defense and launches a fierce attack towards the data center.Right now, wandering hackers are pouring in from all over the world.The number is doubling every minute. Everyone on the podium pondered the message. PRIMEDIFFERENCEBE－TWEENELEMENTSRESPONSIBLEFORHIROSHIMAANDANAGASAKI (The main difference between the atomic bombings of Hiroshima and Nagasaki) "Does it mean combat power?" Brinkerhoff suggested. "Casualties? Economic losses?" "What we're looking for is an exact number," Susan warned, "the estimated loss is too far off. Three thousand miles away, Baker's eyes lit up. "Factor!" he exclaimed. "Youjia is playing a word game! The word 'elements (can refer to 'factor', 'element')' has many meanings! He is talking about chemical elements—not sociopolitical factors! These two The atomic bomb used a different fissionable substance—a different element!" Kusashi clapped his hands and shouted, "That's right! One of these two atomic bombs uses uranium, and the other uses plutonium! These are two different elements!" "Uranium and plutonium!" Jeba exclaimed excitedly, feeling hopeful at once, and turned to face his working army. "The difference between uranium and plutonium! Does anyone know what it is?" Everyone looked at each other. Susan turned around and asked Cao Zhi: "Is there a browser here?" Cao Zhi nodded.Susan grabbed her hand and said, "Come on, let's go surfing." The last line of defense is in jeopardy. Susan and Kusashi stared at the results of an Internet search. "Here are six hundred and forty-seven messages related to uranium, plutonium, and atomic bombs. Feels like this is it." Caozhi opens the link and finds the directory of the file. "Chapter Two!" Susan yelled. "Uranium and Plutonium! Find them!" Cao Zhi found that part of the content.Susan glanced at the data quickly. "A number," Jayba reminded, "We're looking for numbers." Susan read the message left by Youjia again.The main difference between two elements... What we want is a number... "Wait a minute!" "Prime number")' has multiple meanings. Here's another anagram added by Friends—'difference' here means 'difference'." "Yes!" Beck's voice of approval came from the screen, "Actually, this clue is about the difference in prime numbers, not the main difference." 饩浠草⒖桃鹆拜则八湿泪⒁狻!BajuePiSchoolJiyuexin retreats and bears the burden Jebba immediately realized that Susan was right.A prime number has no factors other than the number 1 and itself.In this way, it is impossible for a computer to crack the password through tree factorization, so prime numbers are very useful in the process of writing passwords. Kusashi put in a sentence: "Yes! Exactly! Prime numbers are very important in Japanese culture!" "Even if the password is a prime number, so what! There are too many possibilities." Jebba cried out in pain.A yell came from the back of the room: "TWO MINUTES WARNING!" Susan faintly felt that they were only one step away from success. "We can find out the code!" she said, suppressing her nervousness. "Of all the differences between uranium and plutonium, I dare say that only one can be represented by a prime number! This is our last clue. We will find is a prime number!" "Go ahead," Fontaine ordered.On the schematic diagram, the last firewall is now as thin as an eggshell. "Hey... guys? Remember when I said the bomb dropped on Nagasaki was a plutonium bomb?" "Remember." Everyone replied in unison. "Alas...it seems that I made a mistake." Cao Zhi pointed to the screen. ... It is generally misunderstood that the atomic bomb dropped on Nagasaki was a plutonium atomic bomb.In fact, the material used in this atomic bomb is uranium, and the one dropped on Hiroshima is a sister atomic bomb. "But—" Susan asked hastily, "if both elements are uranium, how can we find the difference between them?" "Perhaps Yuka made a mistake," Fontaine ventured to speculate. "Perhaps he didn't know that two atomic bombs were the same." "No way," sighed Susan. "It's the bombs that crippled him. He must know all about that." Kusashi read aloud: "...the atomic bomb dropped on Nagasaki used uranium-238, an isotope of uranium. This isotope is artificially produced and saturated with neutrons." "238?" Susan exclaimed. "Didn't we just see that the atomic bomb dropped on Hiroshima used another isotope of uranium?" "What's the difference between the two isotopes?" Fontaine asked. "Forty-five seconds!" cried a voice.The last line of defense was almost invisible. "Here!" Cao Zhi pointed to the screen, "Look!" "...the two atomic bombs used different fissionable materials . . . except for a small difference in weight, they were identical." "Atomic weight!" Jeba exclaimed excitedly, "That's it! The atomic weight is the only difference between them! This is the code!" Cao Zhi pulled the page forward. "There it is!" cried Jebba. "That's how much they weigh!" "Thirty seconds left!" "Let's start," Fontaine said softly, "do the subtraction. Hurry up." Jebba held the counter in his hand and began to enter the numbers. "What's an asterisk?" Susan asked. "There's an asterisk after a number! Here's a footnote." That tiny footnote reads: The margin of error is 12%.The figures published by individual laboratories vary. "The last line of defense is about to be breached!" shouted a technician. On the schematic diagram, a large number of black lines surround the defense line, and hundreds of lines are waiting to be connected.On the right side of the screen is Ensei Yuga.The images recording the last moments of his life are played on a continuous loop.Yuka stretched out his finger again and again, and stretched out the ring in front of everyone.He tried to speak, but couldn't breathe, and then he held out that deformed hand... "The intruders are about to attack!" In the center of the screen, the last line of firewall almost disappeared.A large number of black lines surround the center of the circle, forming an opaque, throbbing black mass. "Ten seconds count!" Susan kept staring at Yuga on the screen.A look of despair, a look of remorse. On the screen above his head, David was lost in thought. "The difference," he kept muttering to himself, "the difference between uranium-238 and uranium-235. Should be a simple difference." A technician starts a countdown. "Five! Four! Three!" In less than a tenth of a second, the sound reached Spain.Thirty-three. David seemed to have been hit by a stun pistol again.Three... three... three. 238 minus 235!The difference is 3!He reaches for the microphone... At that moment, Susan stared at Yuka's outstretched finger.Suddenly, through the ring, she saw Ensei Yuka's finger.That's exactly three fingers.It wasn't about the ring at all.Yuga is not telling them something, but showing it to them.He was telling his secret, hoping that someone would understand this... praying that this secret would be conveyed to the NSA in time. "3." Susan whispered in surprise. "It's 3!" Baker shouted from Spain. "We're screwed!" screamed a technician.The schematic diagram began to flicker frantically, and groups of black lines rushed to the center of the circle.The alarm above the head suddenly sounded. "Secret leaked!" Susan's eyes were fixed on her fiancé.His shouts erupted overhead again. "3! The difference between 235 and 238 is 3!" Everyone looked up at him. "The password is 3!" Susan pointed to the screen.Those three fingers were shaking desperately in the Seville sun. "3 is a prime number!" Cao Zhi said involuntarily, "3 is a prime number!" Fontaine asked blankly, "Is it that simple?" "Secret leaked!" a technician yelled. "The database is almost finished!" On the podium, everyone rushed towards the computer at the same time—Susan hit the keyboard all at once.Everyone turned to face the projection wall. enter password? 3 "Definite!" Fontaine ordered, "Definitely!" Susan held her breath, and tapped her finger on the "Enter key".The computer beeped. password confirmed On the schematic above the head, the first of the five firewalls is being restored.The black lines hitting the data center were cut off instantly.Then came the second firewall...and then the third.Moments later, the filters reappear in full.The database is safe and sound.Shouts erupted in the room, and the technicians hugged and celebrated their victory. "Jeba," Fontaine asked, "how much information did they steal?" "Very few," Jebba replied while checking the information on the computer, "very few. And none of them are complete." Fontaine nodded slowly and looked around for Susan, but she was already moving towards the front of the room.On the wall in front of him, David's face filled the screen. "Hey, nice job," he said with a smile. When Susan woke up, the sun was shining brightly.David was watching her silently. David took out a small object and said, "I have something for you." He took Susan's hand and put the object on her finger. It was a white gold ring with a sparkling diamond on it. "Will you marry me?" Standing in the customs office in Osaka, Tokumoto Shotaka stared at the urn, and he regretted it. Customs officials gave him an envelope containing the baby's adoption certificate and birth file. "You are the only surviving relative of this child. After a lot of trouble, we finally found you." On that rainy night thirty-two years ago, he abandoned his physically handicapped son and dying wife. Accompanying the document was a gold ring.Back then, he abandoned his only son; now, cruel fate brought them together like this.
