Take the stairs to the third floor.

No wonder the waiter said that he could see it at a glance, and the entire third floor was such a double-door room, and it was difficult to see it.

An Yi pointed out that looking for the study did mean searching for equipment like the copy of the Deep Mountain Pavilion, but at the same time, he didn't want to get equipment.

This is because if he obtains an item above the normal level in a copy with such a 'modern and modern' background, it means that this is another unscientific copy in the guise of science, and then it is very likely that he will encounter something indescribable, and he is really a little tired.

However, not all items above the ordinary level are enchanted items made of magic, although the probability is very small, there are also things that have been made of magic after a long period of use or a lot of effort by craftsmen, which is natural. And there are also things like the 'Innate Spirit Treasure' in Xianxia, which are inherently strange things or equipment, such as the Eye of Kronos in Ann's pocket, which is the crystallization of the power of the gods after their deaths, and they are also strange things formed by chance.

Of course, whether it is a treasure formed by artificial accident or the so-called innate spirit treasure, the probability of its appearance is low and terrible, and this probability can be ignored under normal circumstances.

But if you don't find any enchanted items, it means that it's a pure puzzle quest, but the final reward is only settlement and experience rewards......

Wanting to get rewards but not wanting to deal with those tentacle gods, An Yizhi was very entangled.

With this tangled mood, An Yizhi reached out and opened the door of the study.

The door is unlocked, and the panel is made of solid wood, which is heavier, but there seems to be a hydraulically assisted mechanism behind the door, and it is not very difficult to open it.

Then what appeared in front of An Yizhi was a super large study room comparable to a small library, not only the walls were full of bookshelves, but also the middle of the room was divided into independent spaces with rows of bookshelves nearly two meters high. There was a sofa in front of him, and a small coffee table next to it for people to use when they were studying.

"Well, I'm afraid the chances of a clue in the book will be very low."

He muttered, then walked into the bookshelf and slowly explored one by one.

If you don't take out all the books and read them, you won't have enough time, even if you read all the titles.

The system doesn't put important clues where it takes a lot of time to explore, and if there is, it's just extra bonus clues or trivial hints.

Because this exploration is so inefficient, the system usually doesn't do it for entertainment reasons.

This is a little trick that players have figured out on their own, after all, there is definitely more than one An Yizhi who has been scheduled for temporary dungeons since the start of the server.

The owner of this mansion is a master mechanic in the setting, and at first An Yizhi thought that his study must be full of books on mechanical engineering, but he didn't expect his study to be so large, and he didn't expect the books in it to be so complete.

All the bookshelves are classified according to the different contents of the books, in addition to the expected books such as mechanical engineering, An Yizhi also saw that there are various bookshelves such as history, law, natural science, etc., the common point is that each bookshelf is neatly stacked, and all the books are arranged according to the alphabetical order A~Z.

This is not an easy task, if the study was organized by the owner himself, he would probably spend a month here, just tidying up the order!

He opened the glass door of the bookshelf and pulled out a copy of 'The Origins of Druidism', a book from the 'Occult' bookshelf category, with stories about the rise of Druidism and nature worship.

In reality, Ann is still quite happy, he likes to read this kind of book the most, but what he needs in the game is clues, and the bookshelf doesn't seem to provide them.

An Yizhi shuttled back and forth between the bookshelves like a horse, and he focused on seeing if there were any books that did not fit this category on the shelves of none of the categories, but there were no books at all, each one was in its rightful place, and it was not messy at all.

If there is something that does not match, it must be clues and hints, and now there is nothing, An Yizhi can only scratch his head and continue to start from other aspects.

"The first thing you see as soon as you walk in is the bookshelves, and your first impression is that there are clues and hints in the book...... Maybe it's a simple thinking trap? ”

An Yizhi muttered this, and then gave up continuing to look for answers in the book, but turned to grope the bookshelves inch by inch to see if there was any mezzanine and room to hide.

But nothing was found.

These bookshelves are made of solid wood, the thickness and style of each board are very ordinary and normal, there is no mezzanine at all, and the back of the bookshelves against the wall also has a little space from the wall, An Yi pointed to the gap behind each bookcase with a match as a light, and there is nothing hidden.

However, it was not without clues, he found that these bookshelves were relatively old, like old furniture that had been used for more than ten years, and there was a big difference between them and the rooms in the guest rooms, including the furniture decoration, which were all newly made.

Could it be that Edward didn't live here in the first place, but just moved his old furniture and renovated all the guest rooms?

This reason is barely plausible, but it does not explain the fact that the wallpaper and other decorations in the study are old.

It is very puzzling that furniture and decoration are different from the old and new, and it stands to reason that there should not be such a big problem.

Still unable to figure out why, An Yizhi had no choice but to continue searching for clues.

"There must be something in the study, not a non-existent set, otherwise it would have been nice to just not be able to open it."

He is right, the system is only AI in the end, he is not a great creator god, everything he does is under the control of the established program, that is, the system will not do useless work.

An pointed up at the ceiling, on which three petal-shaped glass chandeliers lined up, spreading warm light throughout the study.

"There's probably nothing up there......

The study is very high, and if there is something hidden on the ceiling, then you have to use a ladder to get to the ceiling, maybe you can step on the bookshelf, but An Yizhi is worried that if he is not careful, he will be able to knock down the bookshelf. These bookshelves would all fall down like dominoes, and not to mention how much movement it would cause, the mere possibility of crushing him underneath would be enough to keep An from doing this.

"There are no mezzanines on the shelves, no hints for books, no suspicious marks on the walls, and no possibility of hiding things on the ceiling......"

He slapped the door of his head, and there was one place he didn't look.

Floor.

Ann lifted the round carpet with his fingers, and he started at the doorway, and within a few centimeters he was going to tap his fingers on the wooden floor to see if there was anything noteworthy underneath.

Elimination is the simplest and most effective method, and although it is a stupid method, many times the elimination method works wonders.

Sure enough, it wasn't long before he heard a hollow echo on the floor between the two bookshelves, indicating that it was empty underneath.

The location has been found, how to open it?

There are no gaps or gaps in the wooden floor, which means that you need to use a mechanism to open it, considering the strength of the wooden floor, its practical brute force cracking is also possible, but An Yizhi has no tools in his hand.

He looked left and right, but found nothing like a switch, so he made a mark with his pen where he found the hole, and then continued to tap the floor inch by inch.

Eventually, counting the holes he had found earlier, he found two places, one in the middle of the room and one in the corner of the room, next to the leather couch.

Now it's time to think about how to open it.

The trigger points of hidden traps are set in different locations depending on the needs and hobbies of the owner, for example, the most classic 'book mechanism' is used in the dungeon of the Deep Mountain Pavilion.

But there is one point, the location of the trigger must be kept secret and convenient for the owner to use, and it is impossible to run to other rooms in order to turn on the switch in the study, which will be very painful.

To sum up, the switch must also be in the study, just the location......

Ann stood in the middle of the study, slowly looking around, trying to find anything suspicious.

"It's not scientific, where is it?"

He pinched his chin, puzzled.

As mentioned earlier, An Yizhi didn't find anything unreasonable or suspicious in the study, and he was sure that he had turned the whole study through, even the single sofa was almost demolished by him, and no corner escaped his exploration, so he almost took out all the books in the shelves. Even so, a careful carpet search did not find any mechanism.

Can it only be broken by brute force? That's boring, isn't it?

An Yizhi doesn't believe this, the so-called puzzle solving is naturally a contest of IQ, an invisible victory or defeat between the solver and the puzzle solver, if you brute force it, it will be too bad.

- Unfortunately, our protagonist is not such a disciplined person.

"Forget it, converge first, the mechanism can't run away anyway, wait until you have a chance to find a hammer."

Don't think about things that you can't figure out, An Yizhi has a better habit, and a person with obsessive-compulsive disorder must suffocate to death.

He walked to the exit and was about to open the door when he looked up and saw the light switch installed next to the door.

"Grass! I'm so stupid to not even see it so obviously! ”

Reaching out and pressing the light switch continuously, this action should have caused the light to flicker on and off, but the light did not move at all, and instead there were two mechanical sliding sounds in the study.

This mechanism is taking advantage of the blind spot in people's thinking, the lights are always on in the room, and the player will not pay too much attention to the light when he enters the door, thinking that someone has come before him and forgot to turn it off, plus it is raining heavily outside, and the gloomy weather will not make people suspicious of the lights on.

"Let me see what you're hiding, Mr. Edward, I've never met."

The arrangement of these mechanisms aroused An Yizhi's interest, he originally thought that this was a copy of 'murder + solving the case', but now it seems that it is indeed as introduced in the opening CG, with treasure hunting elements, and treasure hunting is An Yizhi's favorite thing to do.

- After all, scraping the ground is three feet long......
