After tearing off all the pages and eliminating the "interference options", Lin Yu and Forbolo soon finished all the "puzzles". The torn pages were spread out on the floor of the whole wooden house. This work was quite time-consuming and labor-intensive, and it was already late at night. The scattered pages on the floor formed four huge numbers. "9", "4", "5", "7". Seeing these four numbers, Lin Yu nodded with great satisfaction. "Okay, the password should be the permutation and combination of these four numbers." "But I don't know what the order is yet..." The four numbers are arranged and combined in any regular pattern, which means 4!=24 possibilities. There is plenty of time to try 24 permutations and combinations one by one.
However, Lin Yu did not dare to gamble - what if this box has some self-protection mechanism, and it will self-destruct if the wrong password is entered? Thinking of this, Lin Yu squatted on the ground and thought. However, Forbolo spoke. "The correct order should be 5497 or 7945... There are only these two possibilities." "I prefer 5497." Listening to Forboluo's words, Lin Yu looked at him with some surprise. "How did you come to this conclusion?" Forboluo shrugged: "It's very simple. These two books are not randomly arranged in a group." "The contents of these books are highly related - they are like textbooks for the same course." "Two similar books usually have similar difficulty." "The difficulty increases in the order of 5497 - the time of the book is also in this order." Forboluo said calmly. Lin Yu felt incredible. "Can you still recognize it after it's painted like this?" "Of course, although it's painted black, the blackened area itself can also represent the number and complexity of the formulas - not to mention that there are actually more obvious hints in the contents of these books." Forboluo said, squatting down, pointing to one of the pages that made up "4" and said, "Look, there is a note in the content mentioned on this page of this book, quoting the content in 5." "This section of 7 is also an extension of 5 - but because 9 mentioned 4 and 7 at the same time, according to the description of 7 on this page of 9, there is a sentence "in addition" before... So I guess 7 should be a subsequent supplement to 4." Forboluo said, Lin Yu looked at him, a little shocked. Although this guy looks out of line, his professional ability as a detective... is really good.
Now Lin Yu is a little convinced that this guy is a professional detective. "You remember all these details." "No big deal, I can even know what these things are talking about through these few words," Forpolo said proudly, "The subjects described in these books are probably about using 'emotions' as fuel and raw materials..." "Click!" The sound of the combination lock popping open interrupted Forpolo. Forpolo looked at Lin Yu with some annoyance: "Hey, why don't you listen to others!" While Forpolo was admiring himself, Lin Yu had already run to open the box. "Sorry," Lin Yu opened the door of the box without raising his head, "I care more about the contents of these books than the contents of these books." "Let's talk about the background setting of this copy later." Lin Yu said, and opened the door of the box. Forpolo looked at Lin Yu and came over: "Well, I am indeed curious about what is in this box." After opening the box... There was a transparent file bag inside. In the file bag, there was a black notebook, a white identity card and a key. It seems to be someone's personal belongings. Lin Yu unceremoniously opened the file bag and then looked at the white ID card inside. On the back was a dark logo of a burning book, and on the front was a simple information about the owner of the ID card. [Name: Will Valletti] [Gender: Male] [Identity: Independent Researcher] [Authorization: B-3] [Region: Dongdong Mountain] Next to it was a photo of a somewhat gloomy curly-haired young man wearing a white uniform shirt. His face was slightly scratched. "It seems that this is the owner of this room." Lin Yu muttered. Then, he opened the notebook. Only the front third of the thin notebook was used, and it was written like a research diary.
"August 7, blizzard. The recorder shows a 'leak' here. Damn, there's not even a living person in this place! How could there be a leak!" "August 10, blizzard. I slept badly last night... I walked around today and didn't get anything... The nearest human gathering points have been abandoned for a long time." "August 15, blizzard. I've been having nightmares recently. This place is terrible. Do I really need to write about the weather? It seems to be snowing here forever! Anyway, I don't have any clues today - I can leave here in another week." "August 16, blizzard. I dug up some very bad things... Have so many people died in this place? And there is no residual soul on the corpses, which is too abnormal!" "August 17, blizzard. There is a monster called 'Chat' in this mountain? My dreams are getting more and more chaotic! When the signal is restored, I will call for reinforcements!" "August 25. Damn, what is the situation in this place? Why is there such a terrible monster? My condition is too bad, I will gamble tomorrow!" "August 26, I understand what happened here... No wonder it was 'leaked', damn, I never thought that 'leaks' would be in this form. This is all our own mistakes! Too tragic!" " I know how to deal with 'Chat'!" The diary stops here. The rest is all blank. Looking at the handwriting of the diary from neat to messy, Lin Yu seemed to feel the increasingly worse mental state of the person who wrote the diary at that time. He rubbed his eyebrows. "It's so complicated." Lin Yu exhaled. The "truth" about this copy is getting closer and closer. However, it also makes Lin Yu feel more and more headache. After all, his purpose is not to restore the truth of this copy, but to find the "liar"... Who set up this "scam" in Zhidong Mountain? Lin Yu still has no clue. On the side, Forboluo spoke again. "Thank you, May! Thank you for bringing me here!" Lin Yu looked at the side, the great detective's tone was sincere. But it was precisely because of this sincerity that Lin Yu was a little puzzled. "No, why are you thanking me?" Didn't he come with a gun against this "detective"? And Forboluo's eyes flashed with eager light. "Because I just thought that this was an ordinary survival copy before, so I subconsciously thought that even if there was any "hidden puzzle", it would definitely not be worth my special trip to solve." "But I was wrong... The puzzles here are very interesting!"
"If you hadn't discovered this place and forced me to come, I might have really missed such a great puzzle!" As Forboluo said, a fanatical expression appeared on his face. "I will find out everything about Chat and this mysterious researcher!" "The truth about this 'Winter Mountain'!"
