Human race, but was chased by girls from all races

……

After hearing what Xu Weiwei said, several people looked at each other, and then no one said anything, just waiting quietly for Xu Weiwei to continue.

"Haven't we just sorted out the information we have obtained?" Xu Weiwei glanced at everyone and said.

"Yes." Shirley nodded.

"We all thought that we had all this information but still couldn't deduce the reason why the librarian fell to his death because we didn't find enough clues. But in fact, this is not the case. The information we have now is enough to make a judgment." Xu Weiwei touched her chin, thinking and speaking seriously.

"Weiwei, please tell me what's going on!" Long Xinyu said anxiously.

"Don't worry, I'll explain it to you slowly." Xu Weiwei smiled bitterly: "After all, I'm just guessing. Although I think my guess is logically correct, I can't guarantee that it is 100% correct."

"Weiwei, you should tell us your thoughts first." Qiuyue said.

"Okay." Xu Weiwei nodded: "Think about it, this cliff library building is 50 meters long, 10 meters wide, and 4 meters high, right?"

Everyone nodded.

"Okay, everyone agrees that a height of 4 meters is not enough to kill a person. Even if it can really kill someone, it wouldn't end up in such a tragic state. There's no objection to this, right?" Xu Weiwei said.

Everyone nodded again.

"In that case, although a fall from 4 meters won't kill someone, let's think about it from another angle. What if the fall height is not 4 meters, but 20 meters, 30 meters, or even... 50 meters?"

"This……"

Everyone looked at each other in bewilderment, and then Shirley continued Xu Weiwei's words: "If that's the case, that height would definitely be enough to kill someone."

"But...where here can there be a height of more than 20 meters for him to fall from?" Aniya pouted her lips slightly and said in a low voice.

"This involves my next conjecture." Xu Weiwei touched her nose mysteriously and said, "The library is a cuboid 50 meters long, 10 meters wide, and 4 meters high. Whether it is 4 meters or 10 meters, it may not be enough to cause a person to fall like this, but... what if the long side is 50 meters?"

When he said this, Lin Tianlang's pupils suddenly shrank. He had roughly guessed what Xu Weiwei wanted to say, and after thinking quickly, he realized that this possibility did exist. And once this possibility was established, it was very likely that this was the reason why the librarian fell to his death, and it might even be the answer to this puzzle!

"You mean... the librarian fell sideways from the left to the right?" Long Xinyu said in an incredible tone: "This is too weird!"

"That's not what I meant, but...what if this library can rotate?" Xu Weiwei explained, "If the entire building of this library can rotate, then when the librarian takes a book from the shelf, the murderer can take the opportunity to activate the library's rotating mechanism and rotate the library 90 degrees! It changes from a flat rectangular block to a vertical rectangular block! In this way, the height of the library is not 4 meters, but 50 meters! The librarian fell from such a high place and fell on the bottom side, which should have been a wall but became the floor after rotation, and was killed!"

At this point, Xu Weiwei's voice gradually became a little excited.

"We don't need to worry about who the murderer is for now, but at least we can infer the cause of death and the specific process of death! Moreover, didn't everyone discover before that the books on the bookshelf are all blank? This must be a hint from the question setter, asking us not to focus on the books. However, the question setter did not erase the title of the book, but kept it, which is also a hint for us!"

"We found that all the books on the bookshelves were placed upside down. Look, the lanterns on the wall are also upside down! This can further prove my guess! The books are upside down, and the lanterns between the bookshelves are also upside down. Is it possible that it is not them that are upside down, but the entire library!"

Xu Weiwei became more and more excited as she spoke, and she even started dancing.

"Because the library can rotate, the place where we are standing is not the floor at all, but the original ceiling! The library is now flipped 180 degrees! So these books and lanterns are not turned upside down, but the library is turned upside down!"

"Then... if that's the case, why is the body fixed to the ceiling... I mean, the current ceiling, where was the original floor?" Lin Tianlang asked, touching his chin.

"I guess this should be a small hint left by the questioner so that we won't be completely attracted by the corpse as soon as we enter the door." Xu Weiwei replied: "The questioner wants to give us some time to find other clues in the library first. Because if the clue about the books and lanterns being reversed is not found, it will be difficult for us to come to this conclusion."

"So, as the puppet butler said, there is a puzzle hidden in this library. As long as the puzzle is solved, we will naturally get the key. So, if the puzzle of the library is for us to find out the real cause of the librarian's death, then the answer is - because the murderer activated the library's mechanism, causing the library to rotate from a flat state to a vertical state, causing the librarian to fall to his death!"

As soon as Xu Weiwei finished speaking, the next moment, the floor under everyone's feet suddenly shook violently, and then the entire library began to shake.

"Not good!" Lin Tianlang yelled.

"What happened!" Aniya said in panic.

At the same time, the floor of the library began to tilt, and it quickly tilted to one side. Xu Weiwei's guess was right! The entire cliff library was a large rotating secret room! And now the secret room's mechanism had been activated, and it began to rotate like a Ferris wheel, with a rotation rate of about 3 degrees per second. At this speed, the library would change from its current flat state to a vertical state in half a minute.

"I guessed right! This is the answer to the puzzle!" Xu Weiwei said loudly.

"Well done, Xu Weiwei! But the most urgent thing now is for everyone to hold on to the bookshelf and not fall down!" Lin Tianlang shouted loudly.

"understand!"

The girls followed suit. The raised part of the bookshelf became everyone's foothold. Everyone stepped on the raised part of the bookshelf, and then reached out to hold on to the bookshelf to stabilize their bodies. This was no problem for the two girls who were more agile, Shirley and Qiuyue. It was not a big problem for Long Xinyu either - after all, she was strong enough, even with one hand, she could hold on to it and not fall.

But for Aniya and Xu Weiwei, it was a bit difficult. The two of them were not very strong, especially Aniya. Fortunately, Mr. Geer's training of Aniya in the past six months was very effective. The most important part was to train Aniya's determination when encountering danger. When the brown-haired girl found that she was not strong enough, she quickly activated the werewolf blood in her body - now she can switch to the wolf form very easily. After switching to the wolf girl form, Aniya's strength increased sharply, and it was no longer a problem to hold the bookshelf and stabilize her body.

However, Xu Weiwei did not have the ability to transform. As far as girls are concerned, the silver-haired girl's athletic ability is actually quite good, but her upper limb strength is still a little lacking, and now the most important thing to stabilize the body is upper limb strength. As the library tilts more and more, it is close to a vertical angle, and the requirements for upper limb strength are getting greater and greater. Xu Weiwei gritted her teeth lightly, but found that her arms were shaking, which made her feel a little panicked.

The library was completely vertical. The body of the librarian who was lying on the ground just now had fallen down and landed at the bottom again. At this moment, the long side of the library had become the high side. Looking down from this position, the bottom was more than 30 meters high, which made people's legs tremble.

"Is everyone okay?" Lin Tianlang held on to the bookshelf tightly and shouted to the girls.

"I'm fine!" Shirley said loudly.

"I'm fine too!"

"me too!"

Qiuyue and Long Xinyu followed closely behind.

"I... I'm fine too!" Aniya gritted her teeth and said. The brown-haired girl was right below Lin Tianlang. Lin Tianlang lowered his head slightly and could see the two cute wolf ears on the girl's head. Even in werewolf form, Aniya was still so cute that she didn't show any offensive power.

"Where is Xu Weiwei?" Lin Tianlang shouted.

"I...I...I don't know..." Xu Weiwei struggled to grab the bookshelf with her hands, her voice trembling. There was also a hint of fear in the girl's eyes.

Although she had gone through a lot of training, when faced with such an emergency, the girl's ability to process information was still far less than Lin Tianlang's experience. In addition, Xu Weiwei herself was a girl from the human world, and it was impossible to completely remove the modern thinking from the human world. She was obviously too nervous and forgot her identity.

"Xu Weiwei! If you can't hold on any longer, use magic! Don't forget that you are a magician!" Lin Tianlang shouted.

Lin Tianlang's words were like a shot of adrenaline into Xu Weiwei's body. The silver-haired girl suddenly became sober: "Float... Float!"

Fortunately, Xu Weiwei has now passed the stage where she must rely on chanting to cast spells. The girl used her control to directly apply magic power to herself, making herself float. After doing this, the girl let out a long breath.

"Everyone, look up!" At this time, Shirley's voice rang out again: "It's the key!"
