"The smell of 'formalin' is not emitted from the back of the door, but from the surface of the door." About ten seconds later, Xiaoling turned on the oil lamp again (because there is not much information on the door, anyone can remember it after a few seconds), and said, "It's just... in normal light, we can't see the liquid applied to the door."

"No... Formalin has no color." Xiao Tan continued, "and won't be in the dark..."

"Nothing is strange." Feng Bujue interrupted him, "This shows that... the liquid on the door is not formalin."

"No... I'm familiar with this taste, probably... it's not wrong." Xiaotan said the second half of the sentence, and he was a little unconfident.

"Because you have a lot of experience in formalin,... when you smell a pungent smell similar to it, you subconsciously bring in this experience, thus creating a wrong conclusion." Feng Bujue said, and had already walked to the door and looked closer.

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 preparation, but a body fluid of some kind of organism..." Jue Ge told the information he obtained from the data level, "Well... it should be the venom secreted by some reptile animal... It contains bee toxins and other things, so it will turn green in the dark."

After saying this, he stopped observing and turned around and said, "Of course... this is not the point." He paused, "The point is... the information depicted by the venom - [20], [19.2766] means."

"Can it be...coordinates?" Buu immediately continued.

"I have also considered this possibility, but there is a problem..." Feng Bujue continued, "Suppose these two numbers really represent a certain coordinate, why is one an integer and the other an accurate to four decimal places?" He glanced into the room, "According to my observation, the length and width of this room are about six meters, two and five meters, one respectively. Accurate these two quantities to centimeters, which are about 620 and 510; identify the coordinates in this range... Is it necessary to use four decimal places?"

"Um...right, too..." Buu nodded and thought.

"Also..." Feng Bujue walked to a corner of the room. "I think the inference of the coordinates is correct. There are four theoretically pointed to the places 20 and 19, namely, 'four areas half a step away from the four corners of the room'." As he said that, he stomped his feet hard, and the floor under his feet made a few muffled "dongdong" sounds, "Well... Anyway, the piece under my feet is solid."

Seeing this, Xiao Tan, Buu and Oub also walked to the other three corners of the room, stamped their feet in the same place and tried it. Nothing special happened.

"So... the coordinate theory is probably wrong." Feng Bujue shrugged and continued, "Let's think about other possibilities, for example, 20 minus 19.2766... ​​is equal to 0.7234, maybe this number..."

"I understand!" Suddenly, Xiaoling interrupted Brother Jue, "It's the coordinates."

"Ha?" Feng Bujue was stunned when he heard this, "What's the solution?"

"Simple, multiplication." Xiao Ling replied, "20 multiplied by 19.2766 equals 385.532. Since there are two sides of the room that are less than 510, if you use a large number such as 385,532, theorems are only two coordinate points." She stamped her feet. "One of them is at my feet, and there is another..." She pointed to the other side of the room, a place that was symmetrical to the coordinates she was stepping on, "And the other point corresponds to the two doors..." She said, and walked around the table, "Use the width of the bottom of the two doors as the bottom edge, each of which makes a vertical line from the point to extend outward, and the two lines will just intersect at 385,532."

After she stood still, she looked at her teammates.

Those five people were silent...

After a while, Buou said: "It is worthy of being Teacher Jue's companion... The puzzle solving techniques are so profound..."

Oub replied: "I am worthy of being Teacher Jue's companion... my computing power is better than ordinary people..."

"Hey! What's his business? I've solved the puzzle, do you want to praise him? "Xiao Ling shouted, "Also, when you praise him, you always have a little bit of it. Why does it become a disgusting word like "tuples" when you come to me? This is just junior high school mathematics! What's the depth? Where does it come from?"

"Okay... don't care about those details." Feng Bujue walked over and stopped Xiaoling from continuing to complain. "They admired you so that's why they said that." While speaking, he had already knelt on one knee and took out the knife at his waist. "Anyway... since the goal has been determined, things will be easy." He knocked the floor with the hilt of the knife, "Well... I'll hear this... there's a chance!"

In the next two minutes, Brother Jue took out the [WJQ-308 Military Shovel], cooperated with [Bell's Daily Knife], and took two steps to lift the floor up neatly.

…………

Here is a distraction. In fact, it doesn’t matter if this puzzle cannot be solved. Theoretically, even if players can’t even find the green words on the door, they can still go out of the room. The solution is... "carpet-style search".

This is a "stupid way", but it is undeniable and very useful.

In the team survival (ordinary) book of "Thriller Paradise", this situation often occurs... Players come to a place where puzzles need to be solved before they can pass, but the members of the team who are good at puzzle solving have already died. At this time, the remaining people will fall into the dilemma of not being able to solve puzzles...

Most of the friends who often play live escape rooms have similar experiences... As long as they are stuck on a puzzle, it is easy to cause "a group of people sitting in the house playing with their phones, waiting for the time to finish".

And in the thriller paradise, what should I do when I encounter this situation? Experienced players know that they have used the "stupid method"...

For example: Someone can't use the "find, replace" function of the document, but he wants to implement this operation. What should he do at this time? Of course, the answer is - use the naked eye to find out the content that needs to be replaced one by one, delete it manually one by one, and re-enter it.

The final result is the same. To put it bluntly, it is just a bit more cumbersome...

…………

"OK, get it done." After Feng Bujue lifted the floor, he saw a rectangular dark box. Just unexpectedly... there was a key hidden inside.

This time, he picked up the key and walked towards the door without words: "I guess... this one still can't be opened." When he said this, he had tried it, but the key and the key did not match, "Well... it was true."

Then, Brother Jue walked towards the door with words and said as he walked: "Because the clue was found from that door, then the props found based on the clue are mostly used to open the door."

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

Click-

With the slight sound of a metal impact, the door lock was opened, and the key immediately turned into white light and disappeared.

"In my experience, if the key is a 'consumable', then its corresponding lock is probably a one-time one." Feng Bujue slowly pushed open the door when he spoke, "that is, from this moment on, this door can be opened at will..."

"Woo--"

At this moment, a strange "shenyin" came from Jue Ge's front.

He immediately looked up and looked at it carefully... but saw that in the dim space behind the door, there was a translucent white shadow... slowly coming from a distance, and the "shenyin" was obviously also emitted by "it".

"Well... this is probably a ghost..." Faced with this creepy scene, Feng Bujue just said calmly, took out his [composite anti-gravity catapult] and walked forward without any hesitation.

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

Under the light, the scenery behind the door appeared - it was just a room similar to that here.

But the place where the White Shadow was standing just now was clearly ten meters away...

"Is it some kind of illusion?" Feng Bujue muttered and walked forward and into the room. "Or... this 'space' will have some changes due to light..."

The teammates behind Ge Jue didn't see the white shadow clearly, but they all heard the "shenyin" sound; after a few seconds of hesitation, they stepped forward one after another and prepared to follow Ge Jue into the door.

But unexpectedly...

Bang--

At this moment, the door closed itself.
Chapter completed!
