"You don't understand, right?" Reinitz smiled as he looked at Als' confused expression. "Let me first tell you what the Chessboard Wheat Theory is. It's a fable from ancient India. "
"The king wanted to reward his minister and asked him what reward he wanted. The minister pointed at the 64 squares of the Go board and said, 'You only need to reward me with a grain of wheat. For example, give me one grain of wheat on the first square, two grains on the second square, four grains on the third square, and eight grains on the fourth square. Each time, double the amount of the previous square.' "
Als was confused. "What does that have to do with anything? And it's not that much … "Each time, it's only double the amount of the previous one.
"Not that much? Do you know how many grains there are in total if we calculate it by doubling the amount of the 64 squares? "
"…"
"It's a total of 18446744073709551615 grains." Reinitz looked at the screen expressionlessly and said calmly, "A hundred years ago, the entire world needed 500 years to produce that many grains."
Als frowned. "But what does this have to do with the forwarding of the email?"
"The program's email forwarding is based on the Chessboard Wheat Theory. Each time it's forwarded, it's double the amount of the previous one. Plus, it's randomly selected mailboxes. It's only used for forwarding, and it's not stored in the forwarded mailbox. The goal is to prevent people from tracing the email's whereabouts. So how do you find it? "
"If we convert the number of grains into the number of times it's forwarded, then in the past hour, it's been forwarded a total of 18446744073709551615 times. If we convert it to time, if we calculate each time by one-tenth of a second, that's 58 billion years. Als, are you sure you want to continue this investigation for so long? "
Als almost spat out a mouthful of blood. "Who is so crafty?! Who created this d * mned program! I'm going to skin her alive! I swear I'm going to skin her alive! Don't tell me there's nothing we can do?! "
Reinitz looked at the results of his investigation, and his eyebrows slowly furrowed.
The program's forwarding numbers were simply geometrical as it traversed the network.
The other party was very cunning. Every mailbox that received mail was also a mailbox that forwarded mail. Just like that, they forwarded mail one by one. In the end, it felt like they had returned to the starting point. Of course, this was an illusion.
Reinitz knew that the documents must have gone somewhere, but he couldn't find out where it was even with his abilities.
If he used the Extreme Method, there might be a chance.
However, even the most powerful supercomputer in the world would need tens of billions of years to calculate such an astronomical amount of calculation.
Can you afford to wait?
Moreover, electronic information spread too quickly. If they couldn't find and destroy it immediately, leaks would be inevitable.
Reinitz sighed and shook his head. "A large-scale leak is inevitable. The only thing we can do now is to activate emergency measures."
"Ah?" Als was stunned. "Emergency measures?"
"Yes, all intelligence personnel should change their keys and stop all activities. All personnel abroad should return immediately. No matter what they are doing, stop immediately." Reinitz paused and said, "Also, the system here is backed up every day. Get me the most recent backup. The other party had deliberately planned to do something big, so they must have started scouting a few days ago. If we want to find traces, we can only go to the system backups from a few days ago. "
"You make the decision. I'll listen to you." Als waved his hand, his face pale.
Reinitz sat alone in the central control room and pulled up the last backup before today's accident.
The system would be backed up twice a day, at 12 noon and midnight. There would be overall backups at different times and different locations.
Reinitz had his own tracing program in the system. After pulling out the backup, he started his own tracing program. Like killing a virus, he began scanning the system before the incident.
This program could detect unstable factors that invaded the system. It didn't necessarily have to be a Trojan horse. As long as it didn't match the system key, it would be marked as an "accidental" program.
It would take at least 24 hours to completely scan the entire system.
Reinitz wasn't in a hurry. He crossed his arms as he sat in the central control room. He was very confident.
He would definitely find this person.
…
It was finally over.
Gu Nianzhi looked out the window and saw that the sky was already bright.
The original desktop appeared on the laptop screen. All traces of her previous input had been erased by the devourer program.
The laptop was now in the same state as before she used DOS to avoid the blocked words.
Gu Nianzhi went to the bathroom to wash her face and took the laptop out to look for the bar owner. "Look, why can't I go online?"
The bar owner seemed to have a lot on her mind. She looked at the computer absentmindedly and said, "It's probably because the circuit here is broken. I can't do anything about it."
"I see …" Gu Nianzhi looked disappointed. "Okay, then I'll go watch a movie."
The bartender couldn't stand Gu Nianzhi's depressed look. He quickly took out his phone and gave it to her. "I have data here. Go play with it."
"Thank you!" Gu Nianzhi's eyes lit up. She shook the bartender's arm in surprise. "Thank you, thank you, thank you!"
The bartender's ears quietly turned red.
The bar owner suddenly turned her head and shouted at the bartender, "What are you thinking?! Are you very rich? You even borrowed money from me yesterday to pay your phone bill! Where did you get the data?! "
Gu Nianzhi was speechless.
The bartender was shocked. He instinctively tightened his grip on the phone and looked at Gu Nianzhi helplessly.
Gu Nianzhi withdrew her hand and said sheepishly, "It's okay, it's okay. I'll go back to sleep."
She took the laptop back to her room and locked the door. She stretched and went to bed.
She hadn't slept the night before and was almost dead tired.
She immediately fell asleep as soon as her head hit the pillow.
…
He Zhichu opened his social media account every day as usual to check the private messages.
His fingers quickly swiped across them. He frowned slightly and was a bit impatient.
There were too many infatuated private messages. If it weren't for Nianzhi, he wouldn't have bothered to read their confessions.
He was afraid that he would miss Nianzhi's private messages because of his impatience. Therefore, even though the veins on his forehead were popping, he didn't say a word and finished reading them all.
With how popular his account was, he received thousands of private messages every day.
It took him a few hours to read them one by one.
He had been in Berlin for two days and had already sent many people to search everywhere, but there was still no news.
That day, the first thing he did when he woke up was to take out his phone to check the private messages on his social media account.
As he browsed through them one by one, his fingers suddenly paused.
He Zhichu sat up in bed. His sleeping robe was half-covered, revealing his exquisite collarbones and well-defined chest. However, his eyes were only fixed on his phone.
There was a private message. There was another private message with only one word on it: "GESTAPO."
He Zhichu was very proficient in German. He only needed one glance to recognize that it was the German abbreviation for "Gestapo."
The fog that had been shrouding him suddenly dissipated. The thing that had been making him feel uneasy for the past few days had finally been confirmed!
He had already begun to suspect that Gu Nianzhi's disappearance had something to do with the German government.
With the intensity of his search, he would have found her long ago if the government hadn't intentionally hidden it.
He had already planned to use other methods to directly pressure the German government if he still couldn't find Nianzhi one day!
This private message from an unknown source confirmed He Zhichu's suspicions.
Only the Gestapo would be able to wipe away all traces of Gu Nianzhi's disappearance.
Normal gangs wouldn't be able to do it.
Haha, the Gestapo?
If they didn't hand over Nianzhi, he would completely change the German Federal Intelligence Agency.
Getting up from the bed, He Zhichu put on his Bluetooth headset and washed up while assigning tasks to his subordinates.
"… Go and find out which strongholds the German Federal Intelligence Agency have in Berlin and want all of their locations. Also, find out if anything special has happened recently. "
He Zhichu's subordinates were very efficient. By noon, they quickly returned with a lot of information.
"Mr. He, the Federal Intelligence Agency has a headquarters in Berlin and a few branch offices. Also, there should be various disguise locations. It's not easy to find them for now, so please give us some time."
He Zhichu frowned unhappily. "Do you think I would let you investigate if I had time?"
His subordinates didn't want to argue with their master, so they could only change the topic. "But yesterday, I heard that the Federal Intelligence Agency suffered a huge setback and is currently in a state of paralysis. Everyone is pretending to be dead and won't speak properly no matter what I ask."
"Oh?" He Zhichu was a bit interested and leaned forward to ask, "What setback?"
"Their internal network was breached last night, and I heard they suffered heavy losses."
He Zhichu was speechless.
"I also heard that the hacker is very powerful. Her codename is' Pink Piggy. '"
He Zhichu: "!!!"
"What do you mean? Why is she called 'Pink Piggy?' "He Zhichu's heart was beating uncontrollably, and his head was starting to hurt again.
"I heard the international hacker community is saying that this' Pink Piggy 'is a young girl and a genius programmer." He Zhichu's subordinates also yearned for this "Pink Piggy," and their faces were full of dreamy expressions as they spoke.
He Zhichu looked at him with disdain and said coldly, "Wipe that covetous look off your face. Is she someone you can covet?"
"Mr. He, I just admire this kind of person. There's no need to use such a serious word as' covet. '" The subordinate was more familiar with He Zhichu, so he smiled cheekily and defended himself.
He Zhichu snorted and gently stroked his delicate jaw with one hand. He looked down at the private message on his phone, "GESTAPO," and said slowly, "Send a letter to the Federal Intelligence Agency. Just say that a friend of mine is a guest there, and it's time to send her back."
