An Xiaoyu didn't expect that Ye Lai would float all the way to the Sanqian Sea of ​​Books, and ran to the door of the Sanqian Sea of ​​Books. She watched Ye Lai pass through the library gate and enter the building, her legs were still weak.

Pulling down the rope from the fifth floor, saying that it was not afraid that it was a lie, but An Xiaoyu didn't know where she got the courage. She climbed down by learning what Chu Sui taught her in the mine cave. She felt that her ability to face stimulation was really strong. Although her palms hurt a little, she was inexplicably excited.

Standing under the steps at the entrance of the Three Thousand Books Sea, An Xiaoyu guessed that Ye came to his home was inside the Three Thousand Books Sea? But when he looked up and looked at the Three Thousand Books Sea, which was still spectacular in the night, An Xiaoyu began to be despaired. How do I find so many floors?

After a while, Hei Niu and Fu Tianxuan also rushed up. The little fat man was almost exhausted from running. He sat on the steps and gasped and shouted, "Run...... I'm running to death!"

Hei Niu ran a little anxiously, and wiped his sweat and asked, "Where did you go?"

An Xiaoyu pointed to the gate of the Sanqian Sea of ​​Books: "I went in from here."

Hei Niu was stunned: "How to find this?"

"That's all...   ..."

After a while, Mus and Yu Beibei also came. They were still riding bicycles, which made An Xiaoyu speechless.

After talking about the current situation, the three unscrupulous guys Fu Tianxuan, Musi and Yu Beibei gave up immediately. One said that Sanqianshu Customs could not enter, the other said that they could not find it even after entering, and the other said that they were sleepy and wanted to sleep.

But what they said was not unreasonable. An Xiaoyu didn't know if the terminal in her hand could open the door of the Sanqian Shuhai like the cabin door of the base. Even if it was opened, if someone found out, she would be denied before school started. She didn't care much, because she was afraid of causing trouble for Ni Yu.

So the boys and girls went back to their homes. An Xiaoyu and the two girls made do with each other in the same room for one night. The next day, they slept until noon. When they opened the terminal, Hei Niu and Fatty also said that they had just woken up and were about to have dinner. Several people made an appointment to meet in a public canteen at the school and discussed what to do next.

Holding half a chicken leg in his hand, Fu Tianxuan suggested: "It's better for us to stay up until two o'clock like yesterday, and then sleep until after two o'clock. That's enough? Didn't I run away yesterday when I opened my eyes that night, which means that his ability is not that high! Maybe he was seen through by me yesterday and was so scared that he didn't dare to come!"

The other four people looked at him strangely, as if he had forgotten who the fat man who was trembling under the table yesterday.

Until the meal, there was no other way. An Xiaoyu could only agree with Hei Niu's method. Anyway, there was nothing to do during the day, so it would be no big deal to stay for a while at night. After the matter was settled, several people started to lose their topics again and sat in their seats to browse the terminal.

An Xiaoyu looked through the forum of supernatural events and read Yelai's posts again. She felt that the security guards had mostly exaggerated elements. Yelai was obviously not that fierce, or was it also affected by the environment? Can you eat people directly during thunderstorms?

At this time, she seemed to know what would happen if the fat man didn't open his eyes? But after thinking about it, she felt that nothing would happen, because on the first night she came, she heard the sound of wind and rain, but nothing happened after she fell asleep.

Only one knows what it is going to do.

The post was flipped down, looking at various titles, similar to the flashes that suddenly appeared in the laboratory, the general teacher walking back and forth in the anatomy room could see two moons in the corridor windows at midnight, and it looked like a scientific secret.

Suddenly, An Xiaoyu's sliding finger stopped and she saw a post that she was interested in now.

Room b0, underground of the library?

An Xiaoyu knew that the library had underground floors, because when I was taking the elevator, in addition to voice recognition, there were two buttons in the elevator, where it was supposed to be the floor buttons, one with b1 and the other with b2.

According to the number of the door number of the door number of the room on the first floor of the underground should be b101, and the second floor of the underground is b201. Why is there a room b0? An Xiaoyu clicked the post curiously and found that the story was quite long, so she put down the terminal and lay both arms on the table.

Start your performance!

The story begins more than 20 years ago. At that time, the structure of the Three Thousand College was similar to that of the present. The Three Thousand Books Sea is also the favorite building of all students in the college. People come here to find ancient books and read books every day.

The author of the post is a person who likes to study. When he was in college, he came to study in the sea of ​​three thousand books almost every day. He also met a few fellow students who also love reading here. In the end, three of them had the best relationship with him. In the last year of college, the four of them came to study together every day.

Seeing this, An Xiaoyu was a little dumbfounded.

Single dogs are terrible.

As I continue reading, the story suddenly changes from the four of them to the deep basic feelings, and begins to describe the structure of the Three Thousand Sea of ​​Books, and rewrites the two layers below the Three Thousand Sea of ​​Books.

There are two floors below the Sanqian Sea of ​​Books, but these two floors are of no use to students. The two floors below the library, or actually the ground and the underground floor, are used to store books and purchase goods.

Why do I say that? Because there is a series of steps in front of the library gate. After the steps are up, it is the first floor of the library. But in fact, there is another floor below it below the stairs. So this floor of the gate is the first floor of the library, and it is actually the second floor above the ground of the building.

The first underground floor of the library, that is, the first floor of the building, has a side door and a back door, which is specially designed for Sanqian Shuhai to purchase new books and store infrequently used books. After the truck is unloaded, it is sent to the first floor of the underground floor. The useless piles are piled on the second floor of the underground. The books placed on the bookshelf on each floor are needed to be delivered to each floor, starting from the first floor of the underground.

These are the two layers below the Three Thousand Sea of ​​Books.

In fact, these two floors can be directly taken from the elevator. Many students in each class went in to read with an adventure attitude, but after entering, they found that the first floor of the underground was full of new books that were not open. The second floor of the underground was full of expired versions and severely damaged, and printed broken books with problems. There was nothing else, so after reading them once, few people went there again.

In addition to some people who are particularly obsessed with books, they are similar to this senior who writes posts.

The four of them gradually developed from reading a lot to collecting rare books. They often went to the second floor of the underground together and searched in the mountains of broken books, hoping to find a fish that had the value of collection, but they couldn't find it until they were about to graduate.

As they were about to leave the school, the four of them had found a job and were about to go their separate ways. They went to drink together. After returning to school, he suggested that it would be better to search for it on the second underground floor of Sanqian Shuhai. Maybe they would find it on the last day? Even if they couldn't find it, it would leave a happy ending for college life.

His proposal received unanimous praise, so the four of them took advantage of the drunkenness to go to the Three Thousand Books Sea.

After entering the elevator, I pressed the button b2 and started waiting for the elevator to arrive. Suddenly a friend joked: "Why are the elevators b1 and b2 like this? Isn't there b0?"

They all want to laugh after hearing this, how can there be something like b0?

But before they could laugh, the elevator's voice recognition server suddenly responded: "The command is received, and is heading to -b0."

This was a bit fantastic. The four of them looked at each other and felt that they had discovered something amazing. Maybe it was the big secret hidden in the sea of ​​three thousand books. In the few seconds of the elevator running, the three thousand emperors, treasures, inheritances, and peerless treasures appeared in their minds.

When the elevator door opened, they couldn't help swallowing and looked out carefully.

Why can't you see anything? Isn't this too dark?

All four of them took out the terminal, turned on the emergency lights, and walked out of the elevator side by side. The lights illuminated the situation in front of them. They looked carefully and found that there was nothing on the B0 floor. They guessed that there were three floors underground in the San Thousand Books Sea, but later they found that only two floors were enough, so they compiled this B3 into B0 and abandoned it.

I was so discouraged. I thought I had discovered the baby, but I didn’t even see any hair. The senior turned around and was about to go into the elevator and rushed back to the dormitory to sleep!

Suddenly a friend said, "Do you see if there is a door ahead?"

The footsteps towards the elevator stopped. The senior turned his head and raised the terminal to look carefully. He found that there seemed to be a door on the wall in front, but he couldn't see clearly. He tried to walk forward a few steps and confirmed: "There is really a door!"

Sure enough, will God still live up to the lucky ones?

The four of them walked towards the front door, and after passing by, they found that there was not only one door on the wall, but also a corridor, which was at the end of the corridor. The senior felt that the narrow corridor was designed like a pity for him.

The door at the end of the corridor is about the same size as the ordinary door, and the width of the corridor is not much different from that of the door. Even if it is squeezed, it is only enough for two people who are not fat to rub past them side by side. The four of them line up in a straight line and walked to the front of the door in a few steps.

After barely squeezing into two rows, they lifted the lights of the terminal and saw the door sign hanging on the door.

“b000”

"What kind of hell sign is this?" asked one person.

The person behind him patted his head: "What are you saying, bad luck, slap, slap!"

The man smiled, spat for two more times, and asked Fat Tiger, no, and asked the author of the post: "What should I do now?"

The senior reached out and knocked on the door, shouting inside: "Is anyone?"

No one responded. After waiting for a while, he knocked three more times and asked louder: "Is anyone? You have delivered the express delivery!"

The four people laughed outside the door, but there was still no response in the room. One person said: "There are no one here to use the floor, how could there be someone inside? I want to see and break into the door and go in."

They were drinking a little too much, but someone suggested that they immediately became crazy. They immediately chose the strongest one and moved to the front door. They were full of energy and kicked them at the door.

After a muffled sound, the door with b000 hanging did not move at all. The guy's legs began to hurt. He rubbed his legs and said, "No, let's have another one together."

Someone immediately responded: "Okay!"

The two of them stood up, made a good stand, and took a kick to the door.

Suddenly, the four people felt a gust of wind blowing. The wind came so rapidly and violently that they could not open their eyes for a while. They blocked their arms in front of them, otherwise they would not even breathe. Then, the wind suddenly became stronger again and blew them all up. They felt that they were blowing from the ground and flying backwards in the air for a second or two, and the strong wind disappeared.

The four people who fell on the ground felt that their butts were about to explode, but when they stood up while rubbing their butts, they found that they were no longer the dark b0 floor beside them, but returned to the elevator door on the first floor on the ground.

This sudden change almost made them think that all this was a dream, but the terminal that fell on the ground was still on the emergency lights, telling them that all this was true.

Later they never went back. No matter what the B0 floor was, they would definitely not want to disturb people. Later, after the senior worked, he wrote such a post on Luanjianshan. Many students tried it in the elevator and found that there was really a B0 floor in the library, and there was such a door on the floor.

No one knows what is inside the door, and no one dares to test it again.

The explanation given by the school is that b0 is the third underground floor that was abandoned a long time ago. At a certain period, the power grid was not as perfect as it is now. b000 once had a high-power backup generator for emergency needs, but later it was useless and of course it was completely locked.

As for the strong winds they felt...
Chapter completed!
