"That smell of 'formalin' doesn't come from behind the door, it's from the surface of the door." After about ten seconds, Xiao Ling turned on the oil lamp again (because there is not much information on the door, anyone can remember it in a few seconds), and said, "It's just ...... In normal light, we can't see these liquids applied to the door. ”

"That's not right...... Formalin has no color. Xiao sighed and continued, "I won't ...... in the dark."

"There's nothing strange about it." Feng Bujue interrupted him, "This shows that ...... The liquid on the door was not formalin. ”

"Won't you...... I'm familiar with this smell, I should ...... You can't go wrong. When Xiao Si said the second half of the sentence, he was a little unconfident.

"Because you have more experience with formalin, you ...... When you smell a pungent smell similar to it, you subconsciously bring in the experience, which leads to false conclusions. Feng Bujue said, walked to the door, and took a closer look.

He turned his back to his teammates, mainly because he didn't want them to see the "black streamer" in his eyes.

"This liquid is not a chemical agent, but the bodily fluid of some kind of living being...... "Jue Ge said the information he had obtained from the number jù level, "Hmm...... It must be the venom secreted by some kind of reptilian animal...... It contains something like bee toxin www.qbwx.com, so it turns green in the dark. ”

After saying this, he stopped his observation, turned around and said, "Of course...... That's not the point. He paused, "The point is...... The message that the venom paints - [20], [19.2766] means. ”

"Could it be...... Coordinate? Buu immediately answered.

"I've considered this possibility, but there's a question...... Feng continued, "Assuming that these two numbers really represent a certain coordinate, why is one an integer and the other accurate to four decimal places?" He glanced around the room, "As far as I can see, the length and width of this room are about six meters two and five meters wide, respectively. Accurate to centimeters, these two quantities are about 620 and 510; Identify the coordinates in this range...... Is it necessary to use four decimal places? ”

"Hmm...... ...... too," Buu nodded and said.

"In addition...... "Leave aside the inference of the coordinates to be correct, and there are theoretically four places to which 20 and 19 point, i.e., 'four areas half a step from the four corners of the room.'" As he spoke, he stomped his foot vigorously, and the floor beneath his feet made a few muffled "thump" sounds, "Hmm...... Anyway, this piece under my feet is solid. ”

Seeing this, Xiao Si, Buu and Ou Bu also walked to the other three corners of the room, stomped their feet in the same place, and nothing special happened.

"So...... I'm afraid the coordinate theory is wrong. Feng Bujue shrugged and continued, "Let's think about other possibilities, such as 20 minus 19.2766...... Equal to 0.7234, maybe this number ......"

"I see!" Suddenly, Xiao Ling interrupted Brother Jue with his mouth, "That's the coordinates." ”

"Huh?" Feng Bujue was stunned when he heard this, "What's the explanation?" ”

"Simple, multiplication." Xiao Ling replied, "20 times 19.2766 equals 385.532, since there are two sides of the room that are less than 510, use a large number like 385,532 to mark it...... Theoretically, there are only two coordinate points. She stamped her foot, "one of them is at my feet, and the other ......" she pointed to the other side of the room, symmetrical to the coordinates she was treading on, "and the other point, which corresponds to the two doors......" she said, and walked around the table, "take the width of the bottom of the two doors as the base, and make a perpendicular line from each of the two doors, and the two lines will intersect exactly at the place of 385,532." ”

She stood still and looked at her teammates.

The five were silent......

After half a ring, Buu said, "He is worthy of being a companion of Master Jue...... The puzzle solving techniques are so deep......"

Ou Bu responded: "He is worthy of being a companion of Teacher Jue...... Computing power is just a lump of strength better than the average person......"

"Hey! What's the matter with him? Even though I solved the riddle, do you want to have something to do with him? Xiao Ling shouted, "Also, when I praise him, it's all 'a little bit', how can it become a disgusting word like 'a lump' when I come here?" It's junior high school math only! What's the depth? Where did you get a lump! ”

"Alright...... Don't worry about the details. Feng Bujue walked over and stopped Xiao Ling from continuing to complain, "They also admire you to say that." As he spoke, he got down on one knee and pulled out the knife at his waist, "Anyway...... Now that the goal has been set, things are easy to do. He tapped the floor with the hilt of his knife, "Hmm...... Listen to this...... There's a play! ”

In the next two minutes, Brother Jue took out the [WJQ-308 Military Shovel], combined with [Bell's Daily Knife], and neatly lifted the floor with a two-pronged approach.

…………

As an aside, this puzzle is actually ...... It doesn't matter if you can't solve it. Theoretically, even if the player can't even spot the green letters on the door, they can still get out of the room. The way to do this is to ...... a "carpet search".

It's a "stupid idea", but it can't be deniably effective.

In the team survival (normal) book of Thrillerland, this is often the case...... Players arrive at a place where they need to solve puzzles in order to get to guò, but the members of the team who are good at solving puzzles are already hanging, and the rest of the team will be left in a dilemma where they can't solve the puzzles......

Most of my friends who play live escape rooms regularly have had similar experiences...... As long as you get stuck on a certain puzzle, it is easy to lead to a situation where "a group of people sit in the house playing with their mobile phones and wait for the time to run out".

And in Thrillerland, what should you do when you encounter such a situation? Experienced players know that using "stupid methods" to get over ......

For example, what if someone doesn't know how to use the "find and replace" function of a document, but he wants to do it? The answer, of course, is to find out the content that needs to be replaced one by one with the naked eye, and manually delete and re-enter them one by one.

The end result is the same, to put it bluntly, it's just a little more cumbersome......

…………

"OK, that's it." After Feng unconsciously lifted the floor, he saw a rectangular dark box, which was not surprising...... There's a key hidden inside.

This time, he picked up the key and walked to the door without words: "I guess...... This one still can't be opened. He had tried it when he said this, and it turned out that the key and the keyhole did not match, "Hmm...... And so it was. ”

Then, Brother Jue walked to the door with the words on it, and said as he walked: "Because the clue was found from that door, then most of the props found according to the clue were also used to open that door." ”

He came to the door and pointed the key at the keyhole again...... This time, it was inserted very smoothly.

Click-

With the soft sound of metal impact, the door lock was opened, and the key disappeared as a white light.

"In my experience, if the key is a 'consumable', then the corresponding lock is mostly disposable." When Feng Bujue spoke, he had slowly pushed the door open, "That is to say, from this moment on, this door can be opened at will......"

"Uh-"

At this moment, a strange moan came from Brother Jue's front.

He immediately looked up and stared intently...... But in the dim space behind the door, there was a translucent white shadow...... It was slowly coming from a distance, and the moan, apparently from "it".

"Hmm...... This is probably a ghost......" Faced with this creepy scene, Feng Bujue just muttered calmly, and unhurriedly took out his [Composite Anti-Gravity Catapult], and walked forward.

However, the moment he turned on the searchlight, the white shadow suddenly disappeared.

In the light of the light, the scene behind the door was revealed—it was just a room about the size of this one.

But the place where the white shadow was standing just now was clearly ten meters away......

"Is it some kind of hallucination?" Feng Bujue muttered as he walked forward and into the room, "Or do you want to ...... This 'space' will change in some way due to the light......"

None of the teammates behind him could see the white shadow, but they all heard the moaning; After a few seconds of hesitation, they stepped forward one after another, ready to follow Brother Jue into the door.

But I didn't expect it......

Bang -

At this moment, the door closed by itself. RS
