Du Qiu felt that he had become a speck of dust, floating in the void, without fear, worry, no sorrow or joy. He watched the people coming and going in the reading room, the lights were on and off, the clock rotated backwards, the four seasons revolved backwards, the air conditioner on the roof degenerated into a fan, the tall buildings outside the window collapsed into flat ground, I don’t know how long it took, but a light "click" sound was heard, the bookmark broke and turned into fluorescence, disappearing, and he landed on the ground and became longer and returned to his original appearance.

The reading room was quiet, with no readers, no lights, but it was not very dark, because there were fireworks outside. The gorgeous sparks reflected rows of bookshelves through the windows, adding a cold and elegant atmosphere to the room. This scene was like a dream, making Du Qiu stunned, not knowing what day tonight.

So amazing!

Did you really travel through time?

Du Qiu was surprised and suddenly felt a bone-thrusting chill. He couldn't help but shivered. So he took out his cell phone from his pants pocket, opened the flashlight APP to shine everywhere, and observed the surrounding situation. He soon found that the overall layout of the reading room had not changed much, but the computer books on the bookshelf had all become social science and humanities. The induction glass door at the exit had become a steel rolling gate, locked tightly, and a piece of A4 paper printed notice was pasted on the wall next to him. When he walked over and looked carefully, he was stunned.

"New Year's Day is a national statutory holiday. The library will close on January 1, 1995 and have a day off. I hereby notify you and ask your classmates to tell each other."

The signature was December 30, 1994, and the bookmark said that it would travel back to the time and space of 5 years old. In 1995, I was exactly 5 years old...

Someone is setting off fireworks outside. Could it be that it is the New Year's Eve in 1995?

Du Qiu took photos around again and found a digital quartz clock on the wall behind the service desk. As expected, the clock showed the date of "January 1, 1995" and the time of "0:04:29". He was surprised and excited, but couldn't help but smile bitterly.

Yuncheng is located between the north and the south, with four distinct seasons. At the end of May, it is approaching summer, with an average temperature of more than 25 degrees, so he only wore a T-shirt and a pair of shorts. January is winter. Although the temperature is not as cold as the north, it is only about two or three degrees at night. If the library is closed for one day, someone will open the door tomorrow morning and close it for more than 30 hours without eating or drinking. Even if he does not freeze to death, he will get seriously ill.

No, you must find a way out!

If it was 2016, Du Qiu could hack the library's CNC access control system and let the glass door open automatically. However, this method was completely ineffective for purely physical rolling gates, so he could only ask someone else to help open the door. He walked behind the service desk, flipped through several drawers, and found a phone number sheet of the school faculty and staff compiled by the Academic Affairs Office. Then, compared the duty check-in form hanging on the wall, he quickly found the contact information of several administrators.

It was very strange to call someone to open the door in the middle of the night. We had to think of a reasonable explanation. Therefore, Du Qiu did not rush to call, but instead endured the chill and sat down on a chair next to the service desk. While sorting out his thoughts and making up lies, he took off his backpack and counted the items inside. Some things were treasures in 2016, but in 1995, some things were ordinary goods, but in 2016, but in 1995, they were priceless, so they had to have a bottom to prevent things from happening.

Key: Whether it is the door key, the car key or the drawer key, it is all useless, but the copper coins hanging on the key chain must be kept, which is a souvenir heirloom from my Mama...

Wallet: The fifth set of RMB issued after 1999, UnionPay cards that were only available after 2002, and second-generation ID cards issued after 2008. All of these are useless. In order to avoid unnecessary trouble, they have to be destroyed...

Book: "The Road to Reality - A Complete Guide to the Law of the Universe", a popular science book published by the master of mathematical physics Roger Penrose in 2004, was just a leisure book that broadened its horizons in 2016, and may have other uses in 1995...

Water cup, tissue, headphones, pen, mouse pad, notepad: These are useful, but not very useful...

Laptop + power adapter + wireless mouse + USB drive: This set of things was a black technology artifact in 1995...

Smartphone + power bank + USB data cable: It is also a black technology artifact, but it is too advanced and has no use in the short term...

Clothing: blue cotton T-shirt, gray casual shorts, low-top canvas shoes, no fancy logo, nor cool style, no era, no big problem...

Backpack: A digital commuter bag handmade by a friend, alternating black and gray color scheme, and a simple and simple style of the cornerstone. Although the design style is not very good with the 1990s, it should not be a big problem...

After checking all the items, Du Qiu put them back in different categories, then picked up the landline on the service desk, used the mobile phone screen as a light, and called an administrator named Su Wenxiu. According to the information on the duty check-in form, there were 6 administrators in this library, which were divided into day shifts and night shifts. Su Wenxiu was on day shift yesterday and was not on the scene when the store closed at night. Information asymmetry was the source of all loopholes. She asked her to open the door, and the lies she made up temporarily were not easily exposed.

As soon as the ringtone rang, a man picked up the microphone. He seemed to be waiting for the phone. He did not be polite, nor asked who it was or who it was. Instead, he said one word concisely: "Speak."

"Sorry, I'm disturbing. Is Teacher Su Wenxiu at home? I'm locked in the reading room on the fourth floor of the library. I want to ask her to come and help open the door."

"Damn! Are there really people locked in the library in the middle of the night these days? Wait a minute... little sister, get up and answer the phone..."

About half a minute later, a girl who sounded soft and answered the phone. After a little question, she agreed with a straightforward answer: "I'll go over and open the door now, very quickly, don't worry."

"Thank you, Teacher Su."

At this time, the fireworks had disappeared, the night was dark and everything was silent. Du Qiu put down the phone, turned off the phone, stuffed it into the innermost dark bag of his backpack, and then held the bag, sat in a daze on the chair, letting his thoughts run wildly like wild horses, and his mood fluttered like waves. After all, 1995 was a good year, and his computer and mobile phone contained a lot of good things.

In 1995, China officially opened the international Internet and GSM mobile phone network, and the network and mobile phone industries were on the eve of explosive development...

In 1995, Amazon was just established, Apple was on the verge of bankruptcy, Yahoo had not registered as a company, and Google did not even have a shadow...

In 1995, the filming of such masterpieces as "Titanic" and "Lord of the Rings" has not yet started, and music experts such as Jay Chou and Eason Chan have not yet made their debut...

Oh, it's great, it seems that you can do anything, and you can make some achievements in everything...

Ah sneezing! Oh, it's so cold...

Du Qiu rubbed his arms and used random thoughts to resist the feeling of getting colder and colder. After about ten minutes, a rustling sound came from outside. With a rumbling sound, someone opened the rolling gate and turned on the lighting in the reading room.

Two people came, one man and one woman. The man looked twenty-five or six years old. He was wearing a black jacket and short hair. He was not tall, but he looked quite strong. The woman was only about twenty years old. She was petite, wearing a goose yellow down jacket and shawl hair. She looked quite handsome. After seeing Du Qiu's condition clearly, the two showed a surprised expression at the same time. The expression was very similar, and they were siblings.

"Brother, you dress like this in the middle of winter, are you robbed or what?"

"No, I'm trying to die by myself." Du Qiu looked cowardly, smiled and touched his head, and told a random story in extremely concise words: "Last night was New Year's Eve. I had a dinner with a few classmates. Later, I got drunk and bragged that I was from Northeast China and was not afraid of the cold. Then everyone started to make bets and asked me to stay in the library all night in T-shirts and shorts, so I came in in a daze..."

He said this, pointed to the notice at the door, and then raised the contact number of the faculty and staff in his hand, explaining: "I was drunk at that time, and I didn't feel that it was cold, nor did I notice this notice. I saw it after the store was closed. After for many hours, I couldn't stand the cold anymore, so I called Teacher Su. I'm very sorry to wake you up so late."

Du Qiu was about 1.82 meters tall, and he deliberately brought a Northeast accent when he spoke, which was very consistent with the image of Northeastern people. Therefore, although this story is not very reasonable, it sounds very affectionate at first glance. The man laughed, looked up at the quartz clock, and teased: "The reading room closed at 10:30, and it is now 12:27. You can't stand it for less than two hours. I'm embarrassed to say that you are Northeastern people?"

"This...haha, actually, we people in Northeast China are quite afraid of the cold. There are heating in the houses in winter, not as dry and cold as Yuncheng."

"You can really mess around!" Su Wenxiu gave Du Qiu a serious sentence with a stern face, questioning: "Before we close the hall, we will inspect the entire reading room to prevent people from being locked in. How did you stay?"

"Just like hide and seek, use bookshelf as a cover and walk around the administrator." Du Qiu gestured with two fingers and explained, then ambushed his strange travels and asked with a bitter face: "Teacher Su, can you be proud of this tonight? Don't report to the leader, and don't tell other administrators that I am a senior and will graduate soon. If I take the punishment, it will affect my job search."

"What are you going to report about such a shitty little thing? After you leave, you hurry back to the dormitory to get dressed, so we can go home and continue to sleep."

Su Wenxiu is young but very cautious. She is not as casual as her brother. She neither gives a guarantee nor lets Du Qiu leave. Instead, she points to the backpack placed on the service desk and asks: "Is that your bag?"

"Yes."

"What are you doing with a bag?"

Backpacks are a hurdle that cannot be avoided. Therefore, when Du Qiu was sorting out the items, he deliberately did not fix the laptop in a dedicated mezzanine, but placed it in the most conspicuous middle layer. In 1995, even desktop computers were not popular yet, let alone laptops. Ordinary people should not be able to see that this is a product beyond the times. He picked up the backpack, unzipped the zipper, and showed it openly: "A relative of me bought me a laptop from the United States. I was afraid that it would not be safe to put it in the dormitory, so I brought it here."

Su Wenxiu's expression was very plain, and she obviously didn't understand computers, but her brother understood a little. After seeing the eye-catching "ThinkPad" logo on the shell, her eyes lit up and she said, "Brother, you are very rich, even IBM's laptop computers. This thing costs at least tens of thousands, right?"

The 2016 ThinkPad is not IBM. It has almost no similarity to the 1995 ThinkPad except that it has black shells. It is very different. Seeing that he knows how to show his stuffing, Du Qiu stuffed half of the notebook back into his backpack and said vaguely: "When my relatives gave it, I didn't mention the price. I don't know how much it costs, I only know it's quite expensive."

"Of course it's expensive. I've seen its advertisements in magazines, claiming to be the best laptop in the world, and is specially used for the Fortune 500 in the world." Su Wenxiu's brother seemed to be an electronics fan. He stepped forward and said: "Brother, turn on the computer and show it to me, and open my eyes. This is the first time I have seen such a high-end computer."

"I can't turn on the computer now. Yesterday, a classmate accidentally sprinkled hot water on the keyboard. The motherboard inside was burnt out. I plan to use it for someone to repair it tomorrow. If it weren't for such a mess, I wouldn't have to get drunk and bet with people and I wouldn't forget to carry it on my back. I really don't feel at ease with my classmates." Du Qiu was quick to make up an excuse and instantly made up a perfunctory excuse, then forced to change the topic, took out the book in his backpack and handed it to Su Wenxiu, and said, "Teacher Su, this is not a library book, I bought it myself."

Su Wenxiu did not doubt that he was there. She looked at the title page and saw that there was no stamp from the library on it. She returned the book to Du Qiu, and then went to the service desk and the bookshelf area to check it. Seeing that all the objects were intact and there was no trouble, she said in an old-fashioned manner: "You can leave, don't make such boring bets in the future. If it is frozen, it's not a joke."

"Don't worry, Teacher Su, I won't know what to do in the future."
