Turing Forbidden Zone

Since the last time the "campus network" was unlocked, the male dormitory seemed to have suddenly opened the door to a new world, and everyone wanted to try to break through the time limit of the campus network.

After a few times of unsuccessful tossing, the dormitory manager gradually accepted the practice of the students out of curiosity, turned a blind eye to this phenomenon, and only symbolically locked the Internet when the leader intervened.

Yan Kairui also used his "unlocking toolbox" to gain face among his classmates, and someone would come to ask for advice after several times.

However, although the time has been relaxed, the bandwidth of the campus network... that is, the speed limit, is still like a drop in the bucket.

At this moment, the download process of the "key" is creeping at a speed of 220KB/s.

It's like a nuclear bomb moving forward on a transport armored vehicle at a slow speed because a 3-year-old child riding a children's tricycle is blocking the road ahead.

Time and night: "..."

Hackers are not omnipotent.

Just like nuclear bombs, apart from detonating in situ, it is not its professional skill.

That night, the other two people in the dormitory could always hear the "humming" sound of the machine in the bed curtain of Shiye.

Yan Kairui didn't know what Shi Ye was downloading, and thought: Anyway, it's impossible to download videos like an ordinary person.

But he knew that Shi Ye should not have fallen asleep all night.

At 7:00 the next morning, Shi Ye had disappeared from the dormitory.

Yan Kairui opened his sleepy eyes, and muttered plainly: "Brother Ye went to exercise again..."

Wang Gu is much more diligent than him, and has always used Shiye's alarm clock to encourage himself-every morning, whenever Shiye wakes up to wash up, Wang Gu will always get up silently and struggling to preview the upcoming professional courses.

However, Wang Gu looked at the time on his phone today, and said in a daze, "Brother Ye is 2 minutes earlier today."

Yan Kairui said vaguely: "Today, the old man is happy."

"It's strange, Brother Ye is always on time..." Wang Gu yawned, "Oh, maybe he woke up early today."

It's not early to wake up at night.

He just stayed up all night, then picked up his notebook in the morning and walked to the library silently.

— instead of living up to his demanding schedule.

Early in the morning, the library was deserted and deserted, and no one appeared, but there were quite a few small things on the table that took up space.

Shi Ye went straight to his usual place, pushed the objects on it aside, opened the laptop by himself, and continued his download thread.

The network situation of the library is much better than that of the dormitory building. At least the download speed has been increased to more than 2MB/s... It will take about 8 hours to complete the download.

"Morning, little classmate."

At this time, a man's voice came from the side.

This is an adult man in his 30s, wearing a dark blue shirt. He should be a very ordinary intellectual, but what is more special is that he has gray hair and some symptoms of premature aging.

Just now he was sitting on the side, seemed to be attracted by Shi Ye's maverick.

Seeing Shi Ye's complexion and dark circles under his eyes, he said in surprise, "This semester has just started, why are you working so hard, didn't you sleep well yesterday?"

Shi Ye didn't speak.

The man didn't feel embarrassed, but persuaded: "Although study is very important, at least you must take care of your health first."

Then, Shi Ye still ignored him, so the latter stopped asking for boredom.

The library remained deserted, and the two were several meters away from each other without disturbing each other.

Shi Ye didn't rest for a long time, he rested his forehead in front of the computer, opened his eyes soon, and looked at what happened in the past few hours first.

After the news of the BitcoinMixer server downtime spread, all parties died down and temporarily entered a state of truce.

However, the economic loss is still expanding every minute, and the top is already devastated.

The administrator of the flower planting field "xyzabc123" came to Signale cautiously again and revealed: [Boss, the above has increased the amount of rewards, as long as you provide information, you can get 20, and you are allowed to use "special means", directly regarded as " Do what is right"...are you busy now? 】

He didn't get a reply until this morning.

[Signale: Soon. 】

Shiye turned off the message, closed his eyes again, ignored the blackness of his vision several times, and clicked on his analysis tool——

From the server of the virus author Barry, he got the disseminated version of the ransomware "Badguy".

Just like other viruses, it is obediently staying in its cage, like an exquisite specimen - the only difference is that it can be resurrected and awakened at any time, sweeping the entire world like its copies.

Shi Ye once saw the D database infected by the virus, which was a huge white tower sealed by a feathered snake.

He believed that the couatle was the electronic form of the "Badguy" virus, but at this time he found that it was not always the case.

He dissected the shell of the virus, analyzed its multiple structures, removed the interference codes left by the author, and observed the content of its real function layer by layer...

He could find the propagation and encryption principle of "Badguy", which is nothing more than a worm structure and AES encryption system, which is not too special technically.

However, its most important core part, the infection principle, is packaged in another self-destructing encryption shell.

Shi Ye tried many times, but couldn't bypass the core self-destruct device, which is almost impossible in theory.

He couldn't find the loophole the virus exploited.

This cunning feathered snake spreads on the network by self-replication and spreading the net, and seals system files with encryption technology, but it does not know what loopholes it uses to invade the victim's system.

The only thing that is certain is that its infected core is definitely not from Barry, but from another person——

That one left a tiny imprint on the self-destructing encrypted shell.

[a butterfly symbol]

It seems that it is some kind of symbolic mark.

As time goes by, Shiye spends more and more time in the electronic world.

More symbols passed before his eyes, and the optical flow formed by the digital information left traces on the retina, which did not subside for a long time, piercing into his tired mind like a steel needle.

The pain is exploding, and the world is starting to spin out of control.

He saw that in the feathered snake specimen in front of him, the pair of wings seemed to be torn apart, extending into the endless void.

He saw a torrent of photoelectrons washing away the walls, ceiling, shelves, and doorways of the library, disintegrating the entire real world into a colorful haze.

Time and space are gone, only the breathtaking silence.

He heard voices from the past.

"Say it! Say it! Can't you see hallucinations?... Tell the doctor what you saw, hurry up!"

"No drinking or eating today, read this book "Signal" for me!"

……

"Uncle Mu, I don't like kid Shiye, he's so weird..."

"No one plays with him, so I don't want it."

……

"Little friend, are you still having hallucinations? I'll prescribe two more doses of medicine for you. Listen to your father and take the medicine on time. These symptoms can disappear..."

……

"This parent, this child is very out of gregarious, and may not be suitable for further study in our school. I can recommend some special schools to you..."

……

"Where's your hallucination? Where's your lyrebird? Draw it and show it to the doctor! Come on, come on! Anything, go lie to the doctor, tell it! Speak up!! I adopted a goddamn deaf Are you dumb and mentally handicapped?"

"Open your mouth."

"You are mentally ill and have problems in your mind, do you understand? At night, you should stay in your study and study well. Apart from reading and programming, you have nothing else to do, you are useless!"

"You can't even do this well, are you worthy of my spending so much money!"

……

"Student, are you okay?"

The gray-haired man suddenly noticed the movement here, and walked over with a little worry.

When he saw Shiye, he ignored him, and continued to lean over his desk, drawing something in front of an open notebook.

He came closer to see:

Shiye was drawing a huge feathered snake.

Shi Ye tore the paper into pieces, and depicted a part of Feathered Serpent on each page.

——The Feathered Serpent is too huge. On each page, only a few strokes are sketched to outline its shape. Only when all the pages are combined can its shape be seen clearly.

Shi Ye murmured: "I can't find..."

"Little classmate?"

The man frowned, as if realizing that something was wrong with his mental state, he reached out and patted his shoulder.

Shi Ye suddenly raised his head, seeing the man in shock.

——What kind of eyes are these? The deep eyes seem to be burning with the blue fire of the winter night, and they are like an abyss-like cold pool, which does not reflect any scene before birth.

—He seemed unable to see everything in front of him.

Shi Ye suddenly pushed away all the pages in an uproar, and walked towards the outside of the library.

"Hey!"

The man froze for a moment, unable to catch up with him for a moment.

When he returned to his seat, he found the pages of paper scattered all over the floor, each of which had a black and white sketch of a bizarre scene.

Among them are huge feathered snakes and little devils with horns, as if some other kind of specimens were preserved in the book.

The man picked up a few of them and only noticed when he put them on the table:

There is also a laptop here, which is humming and seems to be downloading something at a high speed.

The author has something to say: if you are interested.
