3. Running with the ball
“Why is it gone, where did it go…”
At this time, in a bookstore in downtown Huaihai, a young store manager wearing glasses was hurriedly flipping through the books in the store.
After searching for a long time, he found nothing, sitting on the chair, showing an annoyed look: “Isn’t it caught in the gift?” If this is the case, he may have to do the calculation again.
Thinking of this, the store manager showed some headaches.
What the store manager is looking for is actually very simple, just a piece of paper.
On the paper, I remembered a forum URL he wrote down in the morning.
If it’s just a normal forum URL, that’s fine.
But the problem is, this is the website of “Ji Ye”, an extremely secret hacker forum in China.
Compared with ordinary hacker forums, Jiye’s security and privacy are much higher.
In the forum, there are not only great gods from all walks of life, but also a large number of inconveniently exposed trading posts.
Therefore, if you want to become a member of Jiye, you can basically only go through internal recommendation and register an account through an invitation code.
It was only this morning that the store manager passed many tests and obtained Ji Ye’s website from the master.
Of course, in order to keep it secret, the master did not send him the link directly, but gave him a question and asked him to use the algorithm to decipher the numbers and letters inside, and obtain the corresponding website information.
During the calculation process, the store manager recorded the converted letters and numbers on the scratch paper in order.
Later, when a guest came, he inserted the piece of paper into the book beside him.
As a result, when he remembered to “destroy the corpse and destroy the traces”, the piece of paper disappeared.
“However, it should be fine…” The store manager muttered to himself.
His store is not big, and most of the people who come to buy books on weekdays are old people and children.
The one who took the gift today was a young mother who came to buy a drawing book for her daughter.
The mother he knew, whose name was Lin Qingqing, lived nearby and worked as a clerk.
When the programming book she gave her fell into her hands, 80% of it was about to fall into ashes.
Could it be that her children will be free to read programming books?
Besides, in order to prevent unidentified people from breaking in, a pure newcomer will be tested heavily before entering the forum.
Those questions are not something ordinary people can do.
Thinking like this, the shopkeeper felt relieved.
…
On the other side, Lin Xiaotang, who was sitting in front of the computer at home, didn’t know what the shopkeeper was thinking.
When she got home, she turned over all the programming books and taught herself by comparison.
Because of many years of study experience, learning programming languages and programming is not a problem for Lin Xiaotang.
It only took about a month for her to master these contents proficiently.
It’s just that these things are just the foundation after all.
Next, she needs to learn something more esoteric.
At this time, Lin Xiaotang, who was flipping through the book, found a yellowed scratch paper from the “C Primer Plus”.
On it was a line of crooked letters that looked like a link to a website.
Lin Xiaotang didn’t know where this piece of paper came from.
However, considering that it appeared in the programming book, Lin Xiaotang still opened the webpage and entered the URL.
However, to her surprise, after she pressed the Enter key, what popped up on the computer screen was not a web page, but a pop-up window.
On the pop-up window, there is a question recorded –
“Please give the form of motion of a spin magnetic gyroscope in the fourteenth second when it passes through the magnetic field space of the instrument under the Garclo formula.”
Below the question, is a 30 seconds countdown.
Obviously, she must give the answer to this question within 30 seconds.
As the question popped up, her computer seemed to freeze, the mouse couldn’t shake at all, and the shutdown button didn’t work.
The only thing she can do is press the keyboard and enter the correct answer.
After confirming that there was no way to quit, Lin Xiaotang’s eyes fell on this question.
This problem, which seems to be a physics problem, is actually a mathematical problem that requires a lot of calculations.
This may be a bit difficult for an ordinary person, but Lin Xiaotang can easily give the result by mental arithmetic.
What does this topic mean here?
Does she want to try it?
Lin Xiaotang looked at the pop-up window and hesitated.
However, before the countdown was about to end, she moved her fingers and entered the correct answer.
When she typed the last number, another question appeared in front of her –
“Assuming the Shirbo conjecture is true, the plane is arbitrarily subdivided into non-overlapping areas, with 0 and 1 as opposites. , how many distributions will there be?” It
is also a 30-second countdown, which is also an essentially mathematical problem.
This question is slightly more difficult than the previous question.
Intrigued by this reappearing topic, Lin Xiaotang put down the book in her hand and began to immerse herself in computational thinking.
After 3 seconds, she gave the final result.
As she typed the answer, the previous question disappeared and the next question appeared again.
“According to the expansion of the wooden tower, divide a spherical body…”
In this way, as long as Lin Xiaotang completes one question, the next question will appear.
At the same time, the difficulty of these questions is also increasing.
However, the countdown given in the pop-up window is always only 30 seconds.
In the face of such increasing difficulty, Lin Xiaotang’s mentality, from the very beginning of interest, gradually turned into full concentration.
“It’s still a bit difficult…”
Lin Xiaotang was a program created by the Lord of Terror, a special life form built on numbers.
Therefore, she is far more sensitive to mathematics than ordinary humans.
But even so, when faced with these questions, she still felt difficult and difficult.
At the same time, Lin Xiaotang gradually realized that these questions should have been made by several programmers.
The previous topics are still reluctantly based on mathematics and calculations.
But later, the core of most of the questions revolves around programming and operations.
Her only doubt is, what are these programmers creating so many problems for?
Is it difficult, just want to test the newcomers who learn programming?
Lin Xiaotang didn’t learn programming for a long time, so she didn’t feel discouraged by such a difficult test.
On the contrary, the more difficult the existence, the easier it is to arouse her challenge.
Therefore, in the face of these difficulties, not only did she not back down, but she became more and more courageous.
At the same time, she was also deeply curious about the intentions of the few questioners.
After she completed the 99th question, Lin Xiaotang already felt a little difficult.
Thirty, twenty-nine, twenty-eight… three, two, one.
It was almost in the last few seconds that Lin Xiaotang calculated the final result.
After entering the numbers, Lin Xiaotang sighed heavily and leaned on the chair behind him.
At this time, the pop-up window that has remained unchanged for thousands of years suddenly changed!
No more new topics appear, and the pop-up window completely disappears.
In its place is an all black website page.
Countless codes flashed in a hurry, and finally turned into two white Chinese characters composed of countless “1” and “0” –
Jiye.
What the hell is this?
Seeing this, Lin Xiaotang was stunned for a moment.
She thought for a while, shook the mouse, and tentatively clicked the word “polar night” in the center of the screen.
Soon the web page disappeared, replaced by a fairly neatly styled forum.
To enter the forum, you need to register a forum account first.
Seeing this, Lin Xiaotang quickly registered as a member, changed his ID to “Big Devil”, and logged in.
She has done the question for so long, not just out of competition.
She also wanted to know what was behind these topics.
After successful registration, the page jump.
After a while, Lin Xiaotang saw the full picture of this Jiye Forum.
There are many posts on the forum, but the number of registered members is only more than 200.
Lin Xiaotang hurriedly looked over and found that the posts here were either discussing some programming issues or playing dumb puzzles with each other, as if they were doing some kind of transaction.
[Help complete a set of C7 tasks, old rules. ] [Who can do the red domain design of A9 and manage it. 】【Does anyone know about the S area? 】
It can be seen that these people are very careful when speaking.
Many professional words have been referred to by them with other words.
Perhaps out of intuition, Lin Xiaotang thought about the questions he had done before, and then looked at the titles of the posts in the forum, and gradually came up with a guess in his heart.
–hacker.
Under normal circumstances, a secret forum with a small number of people is either a “dark net” or a place where a very small number of special groups gather and communicate.
For some reason, their identities may still not be visible.
Considering that the people here are all programmers, not ordinary programmers, Lin Xiaotang easily thinks of hackers.
She really didn’t expect that she came in in such a place.
Still, that’s not a bad thing.
…
at the same time, in a certain group in China.
[Blue: Someone solved our problem. 】There are only 7 people in this group, most of them don’t usually speak, their avatars are black for a long time, and they look quite low-key.
But with the appearance of this sentence, many members of the group appeared instantly.
[PHP is the best language: wait, are you talking about those questions when you entered the forum? 】【Blue: Hmm. ] [PHP is the best language: … unlocked how many? 】
【Blue: All. 】
After seeing this news from Blue, everyone was silent.
A few seconds later, the group members sent a new message.
[So bald: No way… Those questions, can someone really do it? ? ? 】It’s no wonder they were so excited.
Because these questions are really too perverted!
You know, those questions were basically thought of by the top domestic hackers.
And when they designed this test, they didn’t even think about letting others pass the test!
Each of the questions here has a very large span and is quite difficult, requiring the answerer to have a huge knowledge reserve.
That’s fine, but these questions must be given within 30 seconds.
Even a senior math expert can’t solve 99 questions in one go at such a high frequency!
In order to prevent the answerers from “cheating” by searching for software and calculators, they also set up a program to cancel most of the functions of the computer when answering the question.
The person answering the question can only answer the question by entering numbers and letters, and nothing else can be done.
With these 99 top-difficulty questions, even if the website of their forum were accidentally leaked, it would be difficult for anyone to successfully break in.
But who would have thought that just today, someone actually answered all these questions in one go!
This kind of situation made them feel aggrieved and inexplicable admiration.
Such people, let alone in their hacking world, are rare geniuses even in the world.
But who is this person? !
In the exclamations of everyone, the administrator came out and gave the final order.
[Dog. Management: No matter what, this person must be found out. 】 [Dog. Management: Since he can solve our problem, it means that his level should be similar to ours. We have to find a way to pull him into the group! ]…
Lin Xiaotang doesn’t know how shocked the people in the group are.
She also thought that the 99 questions to be answered when entering the forum were the tests that all members of the forum had to go through.
After confirming that this forum is a hacker forum, she did not hesitate at all, and immediately began to learn the knowledge inside.
I have to say, as the most private and top hacker forum, there are a lot of related technical posts on Jiye.
These great gods do not have much idea of hiding their secrets, and they have published a lot of programming experience and insights.
Lin Xiaotang browsed all the way, and slowly learned a lot.
Before entering here, she will only have the most basic programming.
More esoteric technical content, she is difficult to learn from books.
However, now it seems that this is not a big problem.
Hackers’ techniques fall into two main categories: red domain (offensive) and blue domain (defensive).
Red domain hackers mainly invade other people’s computers, and are good at making computer viruses and cracking coding programs, while blue domain hackers are mainly defensive, and are good at making firewalls and patching loopholes.
Lin Xiaotang took a cursory look, imitating the practices of other Blue Domain hackers, and installed several firewalls on her home computer.
After that, she devoted herself to learning how to hack other people’s computers.
Based on a solid programming foundation, Lin Xiaotang did not struggle at all when learning these things.
Three hours later, she quickly mastered a rough directional tracking technique.
Lin Xiaotang still remembers that her most important purpose in this world is to get close to Qin Yue and complete the rescue mission.
Qin Yue should be only 12 years old and withdrawn. For psychological reasons, he did not go to school, but hired a tutor.
In Lin Xiaotang’s view, such a child can easily spend most of his time and energy online.
However, as the third young master of the Qin family, Qin Yue’s network will naturally be heavily protected.
With Lin Xiaotang’s current technology, it may be difficult for him to investigate his traces on the Internet for a while.
But it is not difficult to approach him through the Internet.
It just so happened that before she knew him as a five-year-old child with her real identity, she also needed a chance to chat with Qin Yue normally and observe him.
Thinking back a little bit in the plot, when Qin Yue appeared, Lin Xiaotang noticed that although Qin Yue caused Lin Qingqing to have a miscarriage, his purpose had always been to help Lin Qingqing and make her happy.
Including before, when Lin Qingqing escaped from the Qin family, he was also a favor.
Are you kind…
Thinking of this, Lin Xiaotang raised her hand and quickly wrote a small program according to a popular routine in previous lives.
Then, through the directional tracking technology, she locked the specific location of the Qin family and sent the applet to it.
…
On the other side, in Qin’s house, Qin Yue found that someone had applied to add him as a WeChat friend.
He glanced at it and found that the person who wanted to add him was a stranger.
This person’s name is “Jia Jia”, and the head is a girl wearing a straw hat, holding tea leaves in her hands, and smiling very fresh and lovely.
