Human race, but was chased by girls from all races

"In short, the cause of death of this corpse is falling. There should be no objection to this." Lin Tianlang touched his chin and said thoughtfully.

"Well. However, the puppet butler just said that as long as we solve the puzzle, we will naturally get the key. There is a problem here. How do we know that the puzzle has been solved?" Shirley said.

"Yes, yes, we have already guessed the cause of death of this corpse. Doesn't that mean we have solved the mystery?" Ania bit her lip lightly, poked at it with her fingers, and whispered.

"Well... I think, if our speculation is correct, it only means that we have only solved part of the puzzle and not completely solved it." Qiuyue said thoughtfully.

"That's right. We only speculated the cause of death, but we didn't figure out how he died." Xu Weiwei said seriously: "Since the cause of death was falling... I think we should deduce how he fell, where he fell, who did it, and so on, before we can truly solve the mystery."

"We don't need to care who did it." Lin Tianlang said, "After all, there is no one else here except us and this corpse. No matter how complicated the puzzle is, it shouldn't involve anything other than the information given in the question."

"The information given in the question... the only information given in the question now is the corpse and the library. There seems to be no other information." Shirley thought and said softly.

At this moment, everyone's brain is running at full speed, and they start to think about the puzzle in front of them. Everyone needs to rely on this limited information to make deductions. This has both advantages and disadvantages. The advantage is that it can limit the divergence of thinking, reduce the possible branches of the question, and fix the answer; the disadvantage is also that it limits the divergence of thinking. If you can't find the right direction of thinking, then you will never be able to completely solve the puzzle in your lifetime.

"Well, let's check again the information we have currently given in the question." Lin Tianlang suggested.

This proposal was unanimously agreed by the girls, and everyone sorted out the information they had at hand.

The first information is about the library itself. This library is a cuboid with a length of 50 meters, a width of 10 meters, and a height of 4 meters. On each of the two long sides of the library, there is a row of bookshelves filled with books. The space inside the library is relatively empty. The bookshelves are not staggered like those in school libraries. There is only a long row of bookshelves on each side.

The second piece of information is about the body that appeared. The gender of the body is male, and the fatal injury is the forehead, where the corner of the forehead was severely hit by a suspected fall injury, and there are bruises and soft tissue contusions on the body. Apart from this, no other wounds have been found for the time being, so it can be determined for the time being that the cause of death of the body is a fall from a height.

The next piece of information is about the library's bookshelves. The books on the library's bookshelves are all blank books with no content, and all the books seem to be turned upside down. Including the lanterns used for lighting between the bookshelves, which seem to be turned upside down. Moreover, each bookshelf has 54 books in a row, which are placed very neatly. Judging from the book titles on the side seals of the books, the books on each large bookshelf are the same, and each large bookshelf will be cycled once.

In addition to the above information, there is no mechanism or secret compartment found on any bookshelf. This is all the information we have at present.

"That's about it." Lin Tianlang said, "This is the information we have found through observation so far. I don't know if there will be other clues, so we may have to keep looking."

"However... based on the information we currently have, it is impossible that the cause of death was a fall." Shirley said softly.

"Yeah, after all, even if this guy is really clumsy and fell down while taking a book from the bookshelf, he shouldn't be in such a miserable state, with a bloody head. And you also said that his skull was shattered at the injured position. Could it be that this person's head is made of tofu? If I fall from a height of only four meters, I may just feel a little pain at most." Long Xinyu scratched his head and echoed Shirley's words.

"Anyway, it's generally unlikely that someone would die from falling from a height of four meters. Even if someone really died, it wouldn't have happened like this. It seems that we may be missing some very critical information." Qiuyue said softly.

"Yes, since the solution to the puzzle has reached a dead end, the only explanation is that we don't have enough information." Lin Tianlang clapped his hands and said, "Then all of us can only keep working hard and continue to look for any clues in the library that we have missed."

"Also, we shouldn't limit our thinking to the library. We can expand our thinking a little bit. Isn't there a small platform outside the library's gate? That should also be the scope of solving puzzles."

"Yes, we have just been searching all over the library and haven't checked outside the library yet!"

Lin Tianlang's words seemed to enlighten Long Xinyu. The red-haired girl shouted excitedly, and then ran out of the library door in a hurry.

"Don't worry!"

Seeing Long Xinyu running away, the others hurriedly followed him. They all came to the outside of the library and squeezed onto the narrow platform. Above the small platform was the top of the sharp cliff, which was very high, at least a hundred meters away from the small platform. Falling from that height would definitely kill an ordinary person.

"Well, everyone, what do you think? Is it possible that the deceased... fell from the top of the mountain and died on the platform?" Ania put forward a guess.

"Yes, yes, that's what I wanted to say!" Long Xinyu shouted, "This mountain top is really high. If I fall down, even I can't say I'm safe. It's normal for that guy to fall to death."

However, before Long Xinyu could be happy for long, Shirley's questioning voice rang out: "No, I don't think so."

"Although the slope from the top of the mountain to this small platform is very high and steep, it is not completely vertical and still has a certain slope." Shirley began to explain seriously: "If the deceased really fell from the top of the mountain, it is unlikely that he fell directly on the small platform. It is more likely that he 'rolled' down."

"And if that were the case, the deceased's injuries would not be like what they were just now. Rolling down from such a high mountain, it is inevitable that he would hit some sharp rocks or something, and he should have multiple wounds on his body." Qiuyue added.

"And even if he didn't roll down, but fell directly from the mountain, from a height of hundreds of meters, it would not be as simple as just smashing his head." Shirley said softly, "It's more likely that his body would be shattered into pieces and turned into a pulp."

"Well……"

After Shirley's explanation, Aniya obviously thought of that scene. The brown-haired girl shrank her neck in fear.

"Well... I am more inclined to Shirley and Qiuyue's statement. I also think that it is unlikely that he fell directly from the top of the mountain. If that were the case, the body would be too complete." Lin Tianlang said, touching his chin.

"Then what exactly is going on?" Long Xinyu was at her wit's end. The red-haired girl yawned and squatted on the ground in frustration: "It's impossible inside the library, and it's impossible outside on the top of the mountain. What else can we do? The only way is that this guy must have fallen to his death somewhere else, and then put his body here!"

When the red-haired girl said this, she had already given up on herself. She didn't like to use her brain and preferred to be straightforward. Now it would be better for her to deal with two giants than to think about these things.

"Besides that, there is one thing we can't explain. That is why the body was fixed to the ceiling when it was first found." Shirley said softly.

Everyone fell silent, and the reasoning once again reached a deadlock. But Lin Tianlang suddenly realized that when everyone was discussing their own ideas, one person had not spoken. Yes, it was the team's "military advisor" Xu Weiwei. Lin Tianlang looked around and found that Xu Weiwei was not even present!

"Huh? Where's Xu Weiwei?" Lin Tianlang asked.

After Lin Tianlang reminded them, the other four girls realized that Xu Weiwei did not come out with them. They were so focused that they did not notice that one person was missing.

"He should still be in the library. He didn't come out with me just now, right?" Shirley said.

Everyone returned to the library. As expected, as soon as they entered the door and looked to the right, they saw the silver-haired girl leaning against the bookshelf next to the corpse, stroking her chin and thinking carefully. If she was given a coat, a round hat, glasses, and a pipe, the silver-haired girl could be transformed into Xu Holmes Weiwei.

"Weiwei!" Long Xinyu shouted.

"Oh...you're back?" Xu Weiwei raised her head, glanced at everyone and responded.

"Why didn't you go out with us just now?" Aniya came up and asked.

"Well... I, I just thought of something." Xu Weiwei said softly: "Did you find anything outside?"

"No." Lin Tianlang shook his head: "What about you? You said you thought of something just now, what did you think of?"

"I... I have a guess." Xu Weiwei turned around and said word by word seriously: "I think I know how this librarian fell to his death."
