Is it really possible that opportunities will come up in a way that you can't believe in waiting?

Believe it or not, this has already happened.

The world has gained strength in its slightness. The power is also so delicate, so delicate that it can be completely ignored. But this delicate force is destined to be decisive.

When the real vision emerged, she knew it was the moment she had been waiting for.

Raise your head, it will be the moment when the sky will fall.

No, to speak of it, she was in the middle of that moment too.

Here, the world will stop. Opportunities will also come at this time.

The so-called opportunity, only once, is very easy to understand. But I never thought it would come this way.

She knew that it could never be done by her, so it was natural that it could not be repeated.

So it's going to be the beginning, but it's also going to be the end.

Hold your breath and start counting down to ten seconds. Everything was as promised.

"Nine,"

It's really strange that I have had a similar experience before, but I don't know why, but this time I actually feel nervous.

"Eight,"

Seriously, what I'm going to do today isn't even much compared to what I was before.

"Seven,"

What is that change?

"Six,"

No, I know it.

"Five,"

In fact, the only thing that has changed is yourself.

"Four,"

My former self was just mechanically moving along the path that had been arranged. Whether you succeed or fail, it has nothing to do with you. Because I'm just a prop to perform a mission, the prop doesn't care about the outcome, so I don't worry about success or not.

"Three,"

However, today is different. Already very different.

"Two,"

Today, I am not here to carry out orders. This is the first time, for the purpose of my clearest purpose.

"One,"

Finally, taking a deep breath, she knocked the carriage enter.

The door opens here.

_

Why is this the only chance?

Because according to someone,Only at this time,The most critical sight of the school city will focus on a certain phenomenon。 To open that door, it is only at this time that it is possible.

She was very confident in her hacking skills, but because of this, she realized that this person was telling the truth beyond doubt.

She couldn't explain why a phenomenon would attract the most crucial attention. But for her, the information itself was an absolute surprise.

As long as that person doesn't deceive himself.

To crack the most confidential key, the software is pre-set by itself. As long as you can be without the gods knowing, there is nothing to worry about.

She said to herself.

Indeed, it is moving in the direction she wants.

As long as it's not noticed, it's worth waiting. Her own goal is just one person.

By and large, the secrecy of computer cryptography depends on the concept of what is known as a "one-way function". That is, the operation of one direction of a function is very simple, but the reverse is extremely difficult. The most classic example of this is the decomposition of prime numbers. Calculating the product of two prime numbers is very simple, but conversely to decompose a large number into the product of two prime numbers, the only way to do this is to use the extremely inefficient "sieve method". In this way, it becomes a one-way channel.

But this is the other way around, that is, as soon as the algorithm is cracked, the channel immediately becomes bidirectional. As long as she manages to get her hands on the key, even if it's just a part, she's confident that she's finding a pattern.

This key is the most critical part that the person gave her. So even if it's constantly changing, you can't escape it.

The matching ratio gradually increased from 1%, although the speed was not slow, but it also made her anxious.

(Just wait a minute, just wait a little longer...... ）

She didn't look up at some pivotal phenomenon. She hopes that this phenomenon will last a little longer, as long as it lasts until the crack is over.

The progress bar kept rising, and the closer she got to completion, the more restless she became. By the last 10 percent, she had completely forgotten about even blinking.

Finally, under her intently watchful gaze, the progress bar came to an end.

(It's done!) ）

With her trembling fingers,Open the deepest secret of the school city。

That's a record that can't even be found in the "library".

That person really didn't lie to her!

She quickly selected the materials she needed to download. Here, there is her last hope......

_

While!

The download of the file is not complete. On the screen of her laptop, a warning prompt popped up.

The hint says: The key is lost.

The cold touch suddenly spread down her back to her brain.

The loss of the key means that the part of the key she got was abandoned by self-discipline. Now, it's true that no one is paying attention to her actions. But the key is no longer valid.

(Isn't that right...... No, how is this possible?! ）

She thought about it.

There's a way to distribute keys that really does that.

You can assume a scenario like this:

If the key is a random sequence of photons, then you can get the key when you know the information about the photons being sent (e.g. polarization). Then you can send the same message to the other party and you can hide the fact that you are eavesdropping. This is the classic view.

But there is one exception - limited by the quantum uncertainty principle, when someone eavesdrops in the middle of the process, even if that person sends the same message, the sequence of data received on the other end will be different!

What if the computer had a program that automatically discarded the key when such a situation occurred?

As a result, the public key system effectively becomes a one-time key system that is used once and then discarded and never used a second time. That is, a theoretically completely secure one-time sticky note key system!

That is, at the same time as she tried to crack the key, she had already been discovered.

Thinking of this, she immediately unplugged the wireless connection.

"Damn!"

After doing all this, she slammed her hands on the table.

It's already the last moment, why is there such a thing?

(Slowly...... ）

She slowly raised her head, the anger in her eyes gradually turning to the deepest trembling.

This only means one thing:

The real secret of the school city,It's encrypted in a way that can never be cracked in theory!

What kind of secret does it need to be guarded in such a way?

She didn't even dare to imagine who would be carrying these secrets. This encryption method alone is beyond the limits of existing computers.

She's already quite aware of the secrets of the school city.。 But even she never knew that there were secrets in the school city that needed to be hidden in such a terrible way.

"Bastard...... Bastard...... Bastard ......"

She buried her head between her hands and cursed incessantly.

Suddenly, she seemed to realize something.

She silently raised her head, looking around with her keen gaze.

In her field of vision, she saw several men.

“……”

In silence, she closed her notebook and stood up, pulled a notepad from the pocket of her school uniform, wrote down a set of numbers and letters, and tore off the page.

She tucked the note between a few banknotes and placed it on the coffee table as if nothing had happened.

"Waiter, check out."

She said to the help desk.

_

Why choose this coffee shop?

Because, this is pre-arranged.

In a word, it's work.

Actually,Try to test the secrets of the school city.,It's just doing something personal while working.。 Waiting for someone is her real job.

She kept a distance and followed behind the men.

(From outside...... ）

It may be a bit rude to say this.,But people in the school city and people outside the school city,The feeling is completely different.。 Ordinary people may not be able to see it, but she has too much experience, and she can tell the difference between the two at a glance.

(and...... Should it be a former peer? ）

Not to mention how interesting, but this situation is really interesting.

(hum...... ）

It's so boring......

Winding around the corner into an empty alley, the men suddenly stopped. They pulled out their guns with surprisingly consistent movements.

"Come out!"

The leader shouted.

Well?

She was stunned for a moment. He pursed his lips and finally came out of the shadows.

"It looks like my skills have regressed."

It's not that she's laughing at herself. She used to be very good at tracking, and it stands to reason that no one should find out about her.

Perhaps, it's because I'm too used to being comfortable.

"Miss, don't underestimate us too much. You're too used to relying on modern technology to understand. ”

Oh?

She seemed to hear something incomprehensible. Listening to the meaning of this, it seems that they discovered her by some non-technological means, so what is it?

Who cares about it?

She is in a very bad mood and is too lazy to bother with this kind of headache now.

"Look down on you guys? Are you getting something wrong? She shook her head helplessly, "Fool, it's good for me to be able to reduce some trouble." Speaking of which, I have to thank you for saving me a lot of trouble. ”

"What do you mean?"

"Nerve-wracking. So I'll just get to the point, right? Keeping you is meant by the above, just to make the line long enough. Now that you've found out, the instructions on it are no longer valid. In other words......" She was slowly, twisting the corners of her mouth into a smile. "You've made yourself useless. Got it? ”

She was like a well-bred lady, but she showed an incomparably distorted smile with impunity. Slowly, step by step, I walked towards the men.

It's just a girl, but it makes people feel suffocated.

The light seemed to fade with her steps. The men looked up in amazement, but were speechless by what they saw.

It's like an invisible river flowing above their heads. In the river, a dark filth was settling, covering the top of their heads like a clot of blood.

"As a gentleman, you shouldn't refuse an invitation from a woman, right? So, let's have some fun. ”

To say stupid, it is. People who don't have self-knowledge, the smarter they are, the more stupid they are.

If they knew about the girl's past, they would know that pretending to know nothing was the only right thing to do.

Now, because of them, the "beast" (The_Beast) is resurrected.

It's quite an interesting coincidence. Because of themselves, they were once called "beasts".
