(The mural in the article was something I saw by chance when I was eating before, and I felt very charming, so I took a picture and uploaded it to Weibo. Pen & Fun & Pavilion www.biquge.info the other is ...... Want to see the answer to the Y-junction? I'm flashbacking again, I'm interspersed again, what's the matter, hit me! ）

Time back to the time when Yiye crossed the river and just started to go downstairs, Feng Yan stepped up to the 6th floor with three steps quickly, there were three offices on this floor, two vice principal offices, and one principal office, Feng Yan quickly came to the two vice principal offices, tried to twist the door handle, and found that it could not be opened, which made him breathe a sigh of relief, which showed that what he wanted to find must be in the principal office, which virtually shortened the search time and reduced the useless work.

It seems that the system is not purely trying to play dead players.,Unnecessary and pure time-wasting plot.,It's not necessary to make it out.,It will reduce the player's impression of the game.,What the system has to do.,It's crazy to set the necessary puzzles to be more difficult.,The place where you really play to death.,Here's it.。

Feng Yan came to the principal's office, kicked the door open, and shouted loudly as Feng Xiaogang learned: "Who else!" ”

The headmaster's office was dark, and no one answered his crazy words.

Feng Yan shrugged, flashed his flashlight, and began to explore the office.

Although the area of this office is large, there are not many things, obviously it should have been moved away later, Feng Yan looked at the empty large office with a flashlight, looked at the few places to explore, and thought about which one to start searching.

At this time, all that was left in the office was an open closet, a mural, and a huge old desk, and all that was scrap paper, broken light bulbs, and a stack of about 10 plastic stools, stacked on top of each other, neatly placed in the corners to eat dust.

"Mom, this was looted by robbers, everything that could be taken was taken away, the projector in Building 3 is very valuable, why didn't anyone rob it, I'll go, bully the soft and afraid of the hard."

The answer to this question Feng Yan is actually very clear, he just complains casually. There are two female ghosts in the No. 3 teaching building, and Zhang Lingfei seems to like the projector, I guess no one can take it away, it's a long life.

"This principal has a unique taste, and he actually likes murals, so let's start searching for the easiest place to hide things."

After Feng Yan finished speaking, he still walked towards the open wall cabinet, this wall cabinet is about 10 meters wide and only a little more than two meters high, and it is made into the form of a bookcase, at this time there are only a few books in the wall cabinet, most of them are empty, and a thick layer of ash is attached to the grid, Feng Yan spent a minute or two to check these empty book grids, knock and knock, and found that there is nothing abnormal, and there is nothing wrong with the books left behind.

The reason why it was quickly judged that there would be no problem with the book was because Feng Yan was speechless and found that the thick books left behind were all imitation books, that is, the kind of books with the Four Books and Five Classics written on the shell, and the sides were very thick, but they couldn't be opened at all, and the whole was an empty book-shaped carton.

"'Beep-'This old guy, what about the principal, I think Bacheng is a bastard who can only take sacks and put money in them, and mislead people's children."

Feng Yan didn't have any mood fluctuations when he scolded these, he just complained casually, because after all, this is just a game, and in terms of setting, there is nothing unreasonable.

There was no clue in the closet, Feng Yan turned to search for the desk in front of him, the desk searched much faster than the wall cabinet, almost at a glance, knocking and knocking at will, Feng Yan came to the conclusion that there was no secret grid here.

"Hmm...... According to the tips of the people who eat melons in the forum, there should be a place here where the principal has hidden those clues, isn't it here? ”

Looking around, the walls of this large office are very large, and the ceiling height is also very high, and the ceiling area above is simply not accessible without the help of tools, if you search by carpet, let alone 20 minutes, 1 hour may not be enough.

It is worth mentioning that the ceiling of this office is made of white gusset, with a small square gusset, interspersed with several rows of LED tubes during the lighting area, as well as several central air conditioning outlets, so that there is no need to install other additional lamps on the ceiling, the whole is a plane, is a typical office office style, this design is placed here, it feels a little strange, after all, this is not an office building, and the principal's office, the decoration style should not be like this.

"There must be a dark grid, but the system deliberately didn't let me find it, indicating that I had to solve the puzzle to get the location of the dark grid, so the hint could only be in one place."

Feng Yan turned his head and hit the mural on the west wall of the closet with a flashlight, and looked at it carefully.

"Ah...... When I look at this kind of painting, I always feel like I have walked into a halal shop, and I kind of want to eat a large piece of mutton. ”

This is a mural of the Western Regions, there are about 30 people in the painting, all of them are portraits of ethnic minorities, at this time, most of these more than 30 people are using their own unique instruments to play, or play, or blow, only a small number of children and women are listening.

The overall painting style is very simple, the alternation of light and dark is not very strong, even everyone's expression is very simple, but with the appearance and action of these people in the performance process, it will appear that their expressions are extremely vivid, in addition to the word forgetfulness, Feng Yan can also think of a word to describe, that is, intoxication.

"Ah...... Really, isn't it embarrassing for me to look for the position of the dark grid in the frame of so many people? However, these people are so religious, and it is not difficult to see from the paintings that they also have a very serious attitude towards music. ”

Feng Yan tapped the flashlight with one hand and the outer thigh of the other hand, turning the flashlight to other parts of the office from time to time, and then quickly projected the light of the flashlight onto the mural.

After looking at it for more than ten seconds, Feng Yan felt as if everyone in the painting was giving him a hint, but after looking at it for more than ten seconds, it didn't seem to be anything special, and after 1 minute, Feng Yan snapped his fingers and said: "It really shouldn't be, this simple puzzle will take more than 1 minute." ”

After saying that, Feng Yan moved the stack of 10 plastic stools he had just seen from the corner, moved them to the northwest corner of the office, and then climbed up to the stack of stools that had increased in height.

The top of this wooden gusset is hollow, relying on the keel support, and the hollow interlayer is a circuit and plays the role of covering the air conditioner.

Feng Yan pushed one of the gussets, and easily lifted the wooden gusset, revealing a black hole, Feng Yan was not afraid of something suddenly coming out of it, and without hesitation, he put his hand in and began to touch it.

After touching it for a few seconds, Feng Yan raised his eyebrows: "Huh? ”
