“That ‘formaldehyde’ smell isn’t coming from behind the door, but from the surface of the door itself.” After about ten seconds, Xiao Ling turned the oil lamp back on (because the information on the door wasn't much; anyone could memorize it in a few seconds), and said, “But… in normal light, we can't see these liquids smeared on the door.”

“Wait a minute… formaldehyde is colorless,” Xiao Tan replied, “And it wouldn't be…”

“There's nothing strange about it,” Feng Bujue interrupted him. “This just shows… that the liquid on the door isn’t formaldehyde.”

“No way… I’m familiar with this smell. I shouldn't… be wrong,” Xiao Tan said, sounding a bit unsure of himself by the end.

“Because you have a lot of experience with formaldehyde, when you smell a similar pungent odor, you subconsciously bring in that experience, leading to a wrong conclusion.” As he spoke, Feng Bujue walked up to the door, peering closely.

He kept his back to his teammates, mainly because he didn't want them to see the “black flowing light” in his eyes.

“This liquid isn’t some kind of chemical reagent, but a bodily fluid of some kind of creature…” Brother Jue spoke out the information he obtained from the data level. “Hmm… it should be venom secreted by some kind of reptile… it contains something like bee venom, so it turns green in the dark.”

After saying that, he stopped observing, turned around, and said, “Of course… that's not the point.” He paused. “The point is… the meaning of the information depicted by the venom—【20】, 【19.2766】.”

“Could it be… coordinates?” Buu immediately replied.

“I’ve considered that possibility, but there's a problem…” Feng Bujue continued, “Assuming these two numbers really represent a coordinate, then why is one an integer while the other is accurate to four decimal places?” He glanced around the room. “According to my observation, the length and width of this room are about six point two meters and five point one meters respectively. If you are going to be precise to the centimeter, that is 620 and 510. Is it really necessary to use four decimal places to mark coordinates in this range?”

“Hmm… you’re right…” Buu nodded, muttering to himself.

“Also…” Feng Bujue walked to a corner of the room. “Let's assume the coordinate theory is correct for now. Then theoretically, the places pointed to by 20, 19 are four places: the four areas that are ‘half a step away from the four corners of the room’.” As he spoke, he stomped his foot hard, and the floor under his feet made a muffled “thump thump” sound. “Well… anyway, this piece under my feet is solid.”

Seeing this, Xiao Tan, Buu, and Oubu also went to the other three corners of the room, respectively, stomping their feet in similar places to test, but nothing special happened.

“So… the coordinate theory is probably wrong.” Feng Bujue shrugged and continued, “Let's think of other possibilities, such as 20 minus 19.2766… equals 0.7234, maybe this number…”

“I know!” Suddenly, Xiao Ling interrupted Brother Jue. “It’s coordinates.”

“Huh?” Feng Bujue was taken aback. “How so?”

“Simple, multiplication,” Xiao Ling replied, “20 multiplied by 19.2766 equals 385.532. Since two sides of the room are less than 510, if we use large numbers like 385, 532 to mark them… theoretically there are only two coordinate points.” She stomped her foot. “One is under my feet, and the other…” She pointed to the other side of the room, the location symmetrical to where she was standing. “And the other point corresponds exactly to those two doors…” As she spoke, she walked around the table. “Taking the width of the bottom of those two doors as the base, and extending a perpendicular line outwards from the midpoint of each, those two lines will intersect exactly at the point 385.532.”

She stopped and looked at her teammates.

The five of them were silent…

After a long while, Buu said, “As expected of Brother Jue's companion… the methods of solving puzzles are so profound…”

Oubu responded, “As expected of Brother Jue's companion… the calculation ability is much stronger than ordinary people…”

“Hey! What does this have to do with him? I solved the puzzle, and you have to drag him in to praise him?” Xiao Ling shouted, “Also, when you praise him, it’s always ‘a little bit’, but when it comes to me, it becomes disgusting words like ‘a lump’? This is just junior high school mathematics! What depth is there? Where does a lump come from!”

“Okay… don't worry about the details.” Feng Bujue walked over, stopping Xiao Ling from continuing to complain. “They’re just admiring you, that's why they said that.” As he spoke, he knelt down on one knee and took out the small knife from his waist. “In short… since we’ve determined the target, things will be easier.” He tapped the floor with the hilt of the knife. “Hmm… listening to this sound… there's hope!”

In the next two minutes, Brother Jue took out the 【wjQ-308 Military Shovel】, and with the 【Bear's Everyday Knife】, he neatly pried up the floor.

…………

Here's a digression. Actually, it doesn't matter if you can't solve this puzzle. Theoretically speaking, even if the players can't find the green letters on the door, they can still get out of the room. The way is… “carpet search”.

This is a “stupid method”, but undeniably, it works.

In Thriller Paradise's team survival (normal) scenario, a situation often occurs… players arrive at a place that requires a puzzle to pass through, but the member of the team who is good at solving puzzles has already been killed. At this time, the remaining people will be in the awkward situation of not being able to solve the puzzle…

Friends who often play live escape rooms mostly have similar experiences… as long as they get stuck on a certain puzzle, it is easy to lead to a situation where "a group of people sit in the room playing with their mobile phones, waiting for the time to run out."

So what should you do in Thriller Paradise when you encounter this situation? Experienced players know that they can pass with the “stupid method”…

For example: someone doesn't know how to use the “find and replace” function of a document, but they want to achieve this operation. What should they do at this time? The answer is of course—use their eyes to find out the content that needs to be replaced one by one, and manually delete and re-enter them one by one.

The final result is the same. To put it bluntly, it's just a little more tedious…

…………

“Okay, done.” After Feng Bujue lifted the floor, he saw a rectangular dark box, and unsurprisingly… there was a key hidden inside.

This time, he picked up the key and walked towards the door without any writing on it. “I guess… this one still can't be opened.” As he said this, he tried it, and the key and the lock were indeed mismatched. “Hmm… just as I expected.”

Then, Brother Jue walked to the door with writing on it, saying as he walked, “Since the clue was found on that door, the props found according to the clue are mostly used to open that door.”

He came to the door and once again aligned the key with the keyhole… This time, it went in smoothly.

Click—

Along with a light metallic sound, the door lock was opened, and the key immediately turned into white light and disappeared.

“According to my experience, if the key is a ‘consumable’, then the corresponding lock is mostly a one-time use.” As Feng Bujue spoke, he slowly pushed the door open. “That is to say, from this moment on, this door can be opened at will…”

“Ooooah—”

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

He immediately looked up and stared… but he saw, in the dim space behind the door, a translucent white shadow… slowly walking from a distance, and that moan was obviously made by “it”.

“Hmm… this is probably a ghost…” Faced with this creepy scene, Feng Bujue calmly muttered, and unhurriedly took out his 【Composite Anti-Gravity Catapult】, and took a step forward.

However, just as he turned on the searchlight, the white shadow disappeared abruptly.

Under the light, the scenery behind the door was revealed—it was just a room about the same size as this one.

But the place where the white shadow stood just now was clearly more than ten meters away…

“Is it some kind of illusion?” Feng Bujue muttered as he stepped forward and entered the room, “Or… does this ‘space’ undergo some kind of change due to the light…”

Brother Jue's teammates behind him did not see the white shadow clearly, but they all heard the moan; after a few seconds of hesitation, they came forward one after another, preparing to follow Brother Jue into the door together.

But unexpectedly…

Bang—

At this moment, the door actually closed by itself.
