How many secrets there are in the sea of 3,000 books, no one has ever made it public. But there is no doubt that even the oldest teachers in the Three Thousand Books cannot know all the secrets in the Three Thousand Books, and even some secrets are hidden deep in the depths of the Sea of Books, never discovered, waiting for the arrival of someone destined.

The Three Thousand Great Emperor only raised his hand slightly when he built the Three Thousand Books Sea, but he was as talented as him, and no one could say whether he would leave his own Dao system and some small treasures in the Three Thousand Books Sea. Whenever the Three Thousand Emperors are mentioned, people think of the legend of the Great War of the Ten Thousand Races.

At that time, the heroes on the continent came out together, science and technology still had no concept for human beings, and countless dynasties of mankind overturned and rose in troubled times, ups and downs, relying on the power of fighting for their lives to the sky.

An Xiaoyu guessed that there would still be cultivators in this world like those in ancient times, but for the stability of the empire, they were all hidden in the shadows, just like a tomb keeper, what kind of person is he? How old did he really live? Why did he maintain the stability of heaven and earth? These are questions that nowhere to ask.

She didn't believe that the splendid cultivation civilization of more than 9,000 years ago would be completely wiped out for no reason after the founding of the country, not to mention that there was still the wisdom left by that civilization, for example, why did you need a specific meridian to drive a mecha?

Since not everyone can have the meridians required to drive a mecha, and in the legend of cultivation, the meridians are used as the route of the cultivator's power, so does it mean that there is a physical gap between people, and only a few people may be qualified to join the ranks of cultivators.

Am I eligible? An Xiaoyu was a little delusional.

Compared with the school's official explanation, An Xiaoyu prefers to believe that in the deepest part of the Three Thousand Books Sea, there is a hidden person with unpredictable abilities, who is in Room B000 on the B0 floor of the Sea of Books. Thinking of this, she immediately thought again, why is he hiding in the special place of the Three Thousand Books Sea, and since he is hiding, why can the elevator still go straight to his floor, and does the night come has anything to do with this person?

Thinking of these questions, An Xiaoyu's heart began to stir, and she desperately wanted to know what was hidden behind this post. So she posted this post to the discussion group in Donghuang and showed it to Hei Niu and a few of them.

After reading it, Black Bull immediately thought of the key: "You mean that Yelai may be on the third floor underground?" ”

An Xiaoyu nodded: "You see that there are so many people on so many floors of the Three Thousand Books Sea during the day, if the Three Thousand Books Sea is an old nest that comes at night, then it is very likely to stay in the three floors where there is no one underground." ”

Fu Tianxuan's small eyes turned around, feeling that something was wrong, when he wanted to come here to meet, it was not that he was scared, but when he heard that there was a beautiful woman, he came over with a fart, and was almost bitten in the face by Yelai.

Now the B0 layer of this sea of 3,000 books is obviously more dangerous, and this group of people is about to go on an adventure again, is it better for them to slip away now?

He thought, pretending to be too full, touching his chubby belly and standing up, muttering, "I'm full, I should go and get some sleep, well, I should..."

As he spoke, he pretended not to see their eyes and walked straight to the door of the cafeteria. Hei Niu sneered behind him: "Put away your clumsy acting skills." ”

Fu Tianxuan paused, turned back with a bitter face and said: "Big brother, Sister An, I think that my body is weak, and it is not very helpful for things like exploration, it is too easy to drag you back, it is better for me to go back to the dormitory and wait for you, in case you can't come back, I can..."

The black bull clenched his fists: "What about your horse?" ”

Fu Tianxuan shrank his head, didn't dare to speak, and returned to his seat listlessly.

An Xiaoyu saw that he was afraid of this, and knew that yesterday's incident had left a shadow on him, so he said: "It's okay, it's daytime now, didn't many people go to the third basement floor to see it before, so it shouldn't be a problem to go in and have a look." ”

Mu Si and Yu Beibei were also a little nervous, and their hearts began to furry when they thought of the shadow and the hideous face they saw on An Xiaoyu's terminal yesterday. We are approached by this thing every night, blowing the wind in our ears? It's scary to think about.

Hearing An Xiaoyu say this, although he felt a little better, he still had some resistance to the dark and uninhabited place on the underground floor of the Three Thousand Books Sea. They can't wait to stay in the crowd at any time, so they feel more secure, and they really don't want to leave.

An Xiaoyu saw that they didn't want to go, and looked at Hei Niu again, and found that this boy was not afraid of anything, his face was all indifferent, so he said: "When the time comes, I will go down with Hei Niu to have a look, and you just wait on it." ”

Fu Tianxuan immediately said: "Okay! Sister An, if you hand over the rear position to our Fu Tianxuan, you can go with confidence and boldness, and I promise to guard the rear properly. ”

Mu Si opened his mouth, wanting to say something, but he still didn't say it. She knew that even if she followed An Xiaoyu, she wouldn't be able to help her in case of a situation, just like last night, she and Yu Beibei could only sit and watch, and they didn't even have the ability to keep up with An Xiaoyu and Hei Niu.

Last night passed, An Xiaoyu didn't know that her status in the hearts of the two girls, Mu Si and Yu Beibei, had been raised to an extremely high level, from their envy of An Xiaoyu's appearance at the beginning, to their trust in An Xiaoyu, and then to their admiration for her bravery and behavior, these An Xiaoyu did not see it, because she had not been worshipped.

Unconsciously, An Xiaoyu has become the default reliance of these five people, and even a strong black bull cannot replace it.

After deciding, the five of them went to the sea of three thousand books.

There are still a lot of people in the sea of books, and the entrance is like the door of a shopping mall, An Xiaoyu looked at these people, a little worried, what if someone goes underground? But she can only hope for it, otherwise she has to come over every day to squat? Isn't that full-fed?

What made her feel a little relieved was that when the downward elevator reached the first floor, the people inside walked out one after another, and there was not a single one left. An Xiaoyu breathed a sigh of relief, entered the elevator with Hei Niu, looked at the time, and said to Mu Si: "If I don't come out after an hour, call the phone I gave you." ”

Mu Si grabbed the terminal and nodded, it was Ni Yu's phone.

Then the elevator closes the door, first on the B1 floor.

B1 is just like what is written in the post, it is a little empty inside, and there are new books piled up on the ground on one side that have not been opened, which are used to replace the books that are damaged in the sea of three thousand books, and the books of three thousand layers, how much do you need to spare the books, it is obviously a huge amount.

An Xiaoyu and Hei Niu took a turn in B1, of course, with a flashlight and the camera function of the spherical terminal, but they didn't find anything, this place was too desolate, which reminded An Xiaoyu of a barren beach overgrown with dead grass in the Jiuxi tribe, no wonder so many people came down to explore, and after seeing it once, they never came again.

The difference between B2 and B1 is that there are bookshelves here, and the bookshelves are lined up with yellowed and worn books, and there are dryers and ventilators running next to them.

An Xiaoyu endured the noise and also turned around, but still didn't find anything. Then now only B0 is left, does the night really have anything to do with the existence of room 000?

Thinking of this, An Xiaoyu was a little nervous, she and Hei Niu entered the elevator and tried to say to the voice recognition server: "B0." ”

"Ding! Command recognition, heading to —B0. ”

An Xiaoyu's heart lifted, and the elevator ran without any sound, but An Xiaoyu felt that the elevator was a little shaky, took out a flashlight from his pocket, opened it in advance, and the elevator door opened.

The two of them glanced at each other and stepped out of the elevator, and sure enough, it was exactly the same as the post said, the entire floor was empty, there was nothing, and the foundation was not as wide as B1 and B2, as if a separate hall had been dug out at the location of the foundation.

How does it feel so like... Tomb? Strange ideas arose.

An Xiaoyu took the flashlight and looked around, carefully looking at the picture coming out of the camera. The whole room was about the size of the entrance hall of the dormitory, the walls were still rough, the walls were not painted, the floors were cement, and in some places there were old cracks, but there was nothing else.

They walked down the stairway across from the elevator door.

The design of this corridor is indeed very weird, and even a little like a spoof, in a space where there is nothing, a passage suddenly opens inward on the wall, and then there is only one door at the end of the passage, and the picture feels weird no matter how you look at it.

But having come here, there is no reason to hold back anymore. An Xiaoyu settled down, walked into the corridor, and carefully looked at the walls of the corridor as she walked inside. The walls of the corridor are the same as the outside, without any decoration, and I reached out and touched it twice, and the touch was also normal.

After walking a few steps, I arrived at the door of the B000. An Xiaoyu looked at this door, which was also the same as the door on the upper floor of the library, but there was no doorknob, what was behind the door? An Xiaoyu thought, hesitated for a while, and reached out to knock on the door.

The black bull stopped her hand and asked, "Do you really want to knock?" ”

An Xiaoyu was a little afraid to do so, but he hesitated even more when he said it, and he didn't know whether to knock it down or put it back with his hand raised. Just when she was still thinking, she didn't expect the black bull to reach out and knock twice on the door, stunned her.

Since it's all knocked, it can only be seen what the consequences are.

As a result, there was no response, the black bull thought about it, reached out and knocked twice, and waited for a few minutes and still had no response. Just as he was about to strike a third time, a strong wind suddenly blew in the corridor, so that they could not open their eyes, and then the wind suddenly increased, blowing them into the air.

Hei Niu stood up on the smooth floor, looked at the three people of Fu Tianxuan in front of him in confusion, and asked, "What about An Xiaoyu?" ”

Fu Tianxuan was surprised: "I didn't see it, you were alone, and you suddenly flew out of the elevator." ”

At this time, An Xiaoyu was so painful that she couldn't stand up, leaning against the wall and rubbing her buttocks, looking at the still dark space next to her, she couldn't find the figure of the black cow.

What's going on? Didn't I get sent out?

She finally made sure that she was still in the corridor, the flashlight fell to the ground, and the light close to the ground illuminated half of the corridor, and suddenly she heard a "click" sound, and looked up suddenly, An Xiaoyu was shocked to see that the door at the end of the corridor that could not be opened no matter how much she knocked was slowly opening a crack in the door.
