"Yueyue, I'm not busy now. Go home first."

"Yes."

Passing by the bookstore yesterday, Jiang Fuyue had a meal at the foot, thought about it, and pushed the door in.

Go straight to the innermost row of bookshelves, next to three bright characters - the old book area.

The cover of the book is old, the dust is very heavy, the stacking is not neat enough, and there is a rotten smell around it. No wonder no one cares.

"Do you sell books here?" Jiang Fuyue found the clerk.

"... you want to buy?!" the other party was surprised.

"Well, how much?"

"Well... I have to ask the boss," because no one has ever bought it, let alone inquired.

Soon, the boss came over and said, "do you want to buy these old books?"

Jiang Fuyue nodded.

"Originally, this area needs to be cleaned up. There are too many old books and take up space. Since you can see them, I'll sell them at a low price. I'll pick one for five yuan."

"Thank you, boss."

"Just a little. Special offers are not refundable. Don't regret buying and quarrel with me."

"Don't worry, absolutely not."

"OK," the boss pointed to the shelf. "Take your time."

Jiang Fuyue is very fast. She will check out at the front desk in a quarter of an hour.

"Oh, that's it?" the boss smiled at her and said that the girl was really smart, but her brain was not very good.

Jiang Fuyue nodded, "pick ten."

"Fifty dollars."

The boss took a big plastic bag and packed it for her. He watched Jiang Fuyue leave and muttered to himself: "it's strange that someone really bought a book without a cover..."

Jiang Fuyue didn't go home, but went to an Internet cafe opposite with a book.

"Please start the machine."

The network manager looked up and said, "student?"

She said calmly, "I'm an adult."

The other party didn't ask her for her ID card, "how long?"

"Two hours."

"Twenty, cash or code scanning?"

Jiang Fuyue: "... One hour is enough."

To this end, she spent the last ten dollars.

Go to the innermost corner, which is just the dead corner of several cameras.

Boot, log in, fingers flying.

The original normal computer desktop got stuck twice and the screen went black.

Jiang Fuyue ignored it and continued to hit the keyboard. A string of codes appeared and soon filled the whole screen.

As soon as the Enter key is hit, the screen suddenly lights up, and then a website landing page pops up.

Jiang Fuyue enters the login name: I'm worried.

Then the six digit password.

After landing successfully, a cluster of fireworks bloomed in the middle of the screen, followed by a large area of purple iris in full bloom, like a welcome feast.

Jiang Fuyue's dark path was bad, so he immediately switched the landing state to stealth.

For a moment, the iris withered and faded out of the table.

She breathed a sigh of relief, took out her mobile phone, sent the cover pages of ten books just photographed in the bookstore to the computer, chose "hide seller information" and set the online auction mode.

Time: 20 minutes.

Meanwhile, state m, California, 0 a.m.

The old professor, who had taken off his glasses and was ready to finish his work, looked up and saw a large piece of withered iris appear on the table, and the trace disappeared in the twinkling of an eye.

His eyes stared round. In a trance, he couldn't tell whether it was a reality or a dream.

A moment later, he almost shook his hands, knocked out the code, switched the screen and jumped out of the home page of the website.

Originally, he was logged in. Because he didn't move the mouse for a long time, the privacy protection clause started the security mode before returning to the computer desktop.

Fortunately, it was in the landing state, so I didn't miss the scene of the defeat of iris just now.

Twenty years

This sea of purple flowers has disappeared for 20 years!

He put on his glasses, clicked on the system message, and a red exclamation point appeared——

[00:07, West 8th District time, the founder sent me to worry and went online]

"It's him! It's really him!"

……

China's Kyoto, scorching sun.

Large Q, room 307, experimental building.

"There it is! There it is!"

The young master student looked at the tutor, stood up from his seat like a madman, stared at the computer screen, and there was a flash of water in his eyes.

"Professor Xu?" he stopped his experiment and prepared to go.

"Nothing... I just..." I'm so happy.

The old man stopped the students from approaching, and then clicked on the background to view the system message——

Sure enough!

It was him!

Just then, the landline rang, but he didn't care to connect. He sat in front of the computer and quickly logged in to the administrator's permission to view the other party's IP address.

The landline stopped and the mobile phone began to vibrate again in the twinkling of an eye.

Xu Kaiqing was impatiently ready to hang up, but at the moment of scanning the caller ID, he quickly pressed the answer button: "Lao bi - he appeared!"

"Xu! He's back!"

They spoke at the same time and were stunned at the same time.

Yes, they all saw it.

Old Peter: "I'm not an administrator, I don't have permission, and California has been very strict in Intranet investigation recently. Now you track the IP address immediately and be sure to find Chou! We've lost his news for 20 years, and there's no next 20 years to wait for!"

"Yes, I know. I'm checking... It's out!"

"How's it going?!"

"..." was silent.

"Xu? Do you hear me? Hello?"

"... the online time is too short to find."

As soon as the voice fell, there was silence.

Suddenly, Xu Kaiqing frowned and saw an auction transaction authorization pop up in the background of the administrator.

He was about to check the details, but he was passed first.

Passed!

Only the founder and administrator have this permission, so——

"Lao Bi! Lao Bi! He's still online! Just passed an auction!"

"Auction?" there came the sound of clacking on the keyboard, "see! Feynman's physics handout 123 volumes were out of print in 87, and Wheeler's unpublished seven volumes of manuscripts. The original is in the national e Museum. Rubbing has been prohibited since 2000. At present, it is no longer in circulation on the market!"

Xu Kaiqing: "the auction ended two minutes ago. The transaction amount shows 20 SA coins in the background."

SA coins, virtual banknotes for internal transactions on the website.

One SA coin is about 10000 yuan.

After the auction is completed, the money will be temporarily transferred to the intermediate account, which can be transferred to the seller's account only after being approved by the administrator.

And this transaction is authorized by "worry", so can it be considered that

Chou is the seller of these ten out of print books!

Xu Kaiqing was ready to view the seller's message, but a dialog box popped up in the background of the administrator——

[I'm worried]: long time no see, Xu.

[Xu]: are you back?!

[I'm worried]: Yes. Could you change SA coins, please.

[Xu]: of course! What currency would you like?

[I send worry]: RMB.

Xu Kaiqing's breath stagnated, which shows that... Others are in China!

[Xu]: OK. Or to the space account?

[I'm worried]: HMM.

Thirty seconds later, Jiang Fuyue received an accounting reminder.

[I'm worried]: Thank you.

[Xu]: is it convenient for you to meet now? Less than half of the experiment was completed, Peter and I fell into a dead end.

[I'm worried]: no hurry. It's time. I'll meet you naturally.

After typing this sentence, the other party will show the offline.

Xu Kaiqing only tracked the IP address in linhuai, but he couldn't find the specific location.

But it was enough to keep him excited.

"Xiao Zhang -"

"Coming! Old Xu!" the assistant heard the sound and trotted in from outside.

Xu Kaiqing: "help me book a ticket to linhuai!"

"Now?"

"Yes! The sooner the better! I'll go back to pack my bags and let the car drive downstairs..." he said, took off his experimental robe and strode away.

"Hello? Hello?! Xu -- can you hear me?" it turned out that the mobile phone was still on the phone, and old Peter's anxious voice came from inside, "you found Chou, didn't you?"

"No. But I have to go myself."

"OK, I'll book the ticket right away."

"No, don't hurry. Wait until someone is found. The top priority is to sort out all the experimental data. I have a hunch that it will come in handy soon."

"... OK."

Xu Kaiqing ended the call. He had walked to the entrance of the stairs and found that he had forgotten to take the computer. He quickly folded back, took the computer and left like a gust of wind.

But one detail was ignored. The computer was turned on, but now it is closed.

The master student gently breathed out a mouthful of turbid Qi, with some fear.

Then he came to a doctoral student in the same laboratory——

"Elder martial brother, I have something to do with you."

"Huh?"

"What website is s-sa?"

The doctor's face changed slightly: "where did you know?"

"... I helped Professor Xu turn off the computer just now, but I didn't mean to peek! Elder martial brother, is there anything special about this website? I feel that the teacher is too secretive to mention it."

"In fact, it's not as mysterious as you think. S-sa, fully known as science sale, is also called 'KEPAI station' in China, which is used for Discipline data sharing and trading. It is said that there are a large number of out of print scientific research materials and first-hand manuscripts," paused and added with a smile, "the kind that can be used for collection."

"And this kind of website? How come I've never heard of it?"

"S-sa has a membership system. Only the world's top scientists in various fields have the starting qualification, and this group of people can authorize three admission places. It is said that there are less than 50 starting members in the world. If these people use the invitation authority, they will add up to only 200. It's strange that you can't even hear of small shrimps like us. I didn't know it until last year ……”

"... there is really no information on the Internet." the master released the mouse and looked stunned.

It feels like

The world he had known was suddenly no longer the same after opening a door.
