Yao Xiaoxin......

It's a very common name.

And the owner of this name is naturally an ordinary girl.

At least it looks ordinary.

She is 22 years old, which is the best age for a girl.

In this age where elements such as naïve, sexy, intellectual, and charming can be controlled at will. Yao Xiaoxin did not choose to pursue love, beauty, and career.

Instead, she chose to become a glorious otaku.

It's the kind that goes to death.

However, this choice also fits her personality perfectly.

After all, she began to walk the streets at the age of 14, learned to smoke at the age of 16, began to drink at the age of 18, and then in her 20s, she wore a home T-shirt, stepped on slippers, stared at the dark circles of insomnia, held a cigarette in her mouth, held wine in her hand, and sat on the side of the road looking at the stars at midnight.

Of course, this decadence is just an image of her exposed to people, and her real image ...... It's even more decadent.

Yao Xiaoxin has had insomnia since she was 16 years old, and she doesn't know what, her brain is very active, so active that when she sees something, she begins to analyze it uncontrollably.

For example, a wallet that fell to the ground, the first second Yao Xiaoxin saw it, she began to observe the thickness of the wallet, guessing how much money was inside, whether it was a card or money, what the owner of the wallet was doing, under what circumstances would he lose the wallet, why the edge on the left side of the wallet was older than the one on the right, and why there was a wear zone of less than half a centimeter at the opening.

In short, Yao Xiaoxin just couldn't control her desire to think.

Moreover, she seems to be gradually suffering from a disease called [Hyperamnesia], which causes the patient's memory to uncontrollably absorb all the information around her and make it difficult to forget.

Some people may say that this disease is simply the gospel of scumbags, and you won't forget it after reading a book, so no one can stop it when you take the exam.

Yes, it is convenient to take exams, but there are more exams in life.

Hyperamnesia patients are very painful, because they can't control what they should remember and what they shouldn't remember, and the first second they open their eyes, they start ingesting information, the meal you had at noon on the second Thursday of May three years ago, and to this day, you can't forget that taste.

You can vividly recall every minute of the past few years, and you can remember every second of pain in every wound.

This unforgettable pain has made more than 50% of people with hyperamnesia become crazy.

So Yao Xiaoxin is also about to go crazy...... She had to suppress her mind with the hardest puzzles and make it have something to do, or else her mind would have to start thinking about itself.

She began to solve puzzles everywhere, the more difficult and unbelievable the better, but there were still too few puzzles. So 8 years ago, she became a web editor in 20 minutes, built a website for herself, and became the most powerful hacker in the world in two hours.

She began to solicit puzzles from all over the world, hacking into police archives around the world to look through old mysteries.

Soon, the "guesser" of this almost impossible puzzle came into people's attention and became famous.

At that time, Yao Xiaoxin felt that she should also have a code name, so she began to call herself X.

This code name is not used to highlight the force, but the initial letter of the word [Xin] in her name is X.

So, how much identity does X have?

She is the strongest hacker in the world.

is the strongest detective in the world.

He is the only person in the world who has solved the fourfold theoretical equation without the help of a computer.

He is the number one Go player in the world, a chess player, and a record holder in all chess challenges, including mahjong.

Of course, there are many, many other identities, and these identities are all used by her under different names, and she never shows up in all the events, she only competes online. So much so that many pros believe that this guy is not a human at all, but a supercomputer or something.

But Yao Xiaoxin doesn't care, what she has always pursued is to make her head tired and then sleep.

......

Today is Thursday...... It's been three full days since Lao Ka handed over the letter with [X] written on it to the supermarket salesperson.

At 5 o'clock in the morning, Yao Xiaoxin, who forcibly hypnotized herself with alcohol, woke up again, she scratched her messy long hair, and subconsciously reached out to get the wine bottle next to her.

But before she could touch the bottle, she knew that there should be less than a mouthful left in the bottle.

Without alcohol, Yao Xiaoxin couldn't have fallen asleep, so she sighed helplessly, took out a cigarette, lit it, and walked out of the bar.

The street at 5 o'clock was very deserted, and at this juncture where the sun and the moonlight alternated, Yao Xiaoxin looked at the empty street in a daze.

She was waiting for the supermarket across the street to open so she could buy some more drinks.

Finally, the time came to half past eight.

A supermarket cashier came to the door of the supermarket and opened the door. At this time, Yao Xiaoxin had been leaning against the door and waiting for a long time.

"Heh, is there no smoke or no alcohol this time?" The cashier asked with a smile.

"Wine~" Yao Xiaoxin responded helplessly with dark circles under her eyes.

The staff at this supermarket all know Yao Xiaoxin because she definitely comes almost every few days, and every time she comes, she buys a lot of alcohol and cigarettes.

To be honest, it's hard to like such a guy who doesn't leave cigarettes and alcohol, but the male clerks in this supermarket seem to like her very much.

Because she has a unique temperament, although she can't say it, but it can make people hate her less.

And in addition to smoking, drinking, no makeup, sloppy face and dark circles, and slippers that have not been changed for a long time, this girl is quite beautiful.

"I said, eldest sister, you always drink like this, will you drink yourself out of illness?" The clerk looked at the two bags of wine on the cash register and asked with a wry smile.

"I'm already sick." Yao Xiaoxin yawned in response.

"If you're sick, you have to take medicine!" The clerk seemed to want to care about Yao Xiaoxin.

"Yes, isn't this medicine~" Yao Xiaoxin gestured to the wine.

The clerk shook his head helplessly, and then began to scan the code for all kinds of wine.

And at this time, Yao Xiaoxin suddenly saw a letter behind the cash register.

"Huh?" She pointed to the letter with dark circles in her eyes: "When did that letter arrive?" ”

The clerk glanced back: "Oh, you said that envelope, three days ago, a very strange uncle sent it here, saying that I should collect it on my behalf, but after so many days, no one came to pick it up...... I guess the uncle got it wrong. ”

Yao Xiaoxin stretched out her head, still looking at the letter: "Oh~ Is there an X drawn on that letter?" ”

“？” The clerk was stunned for a moment, then turned around, took the letter in his hand, and looked at it: "Yes, hey, you...... You won't be ......"

"Oh, I'm sorry, this letter is for me." Yao Xiaoxin scratched her head and said.
