"What is your name?" "Do you believe in the existence of God?"
Meng Nan suddenly sat up from the ground and looked around with vigilant eyes.
This is an empty cubic room with a length, width and height of about 4 meters. The surrounding walls have regular patterns, which looks full of technology.
There is a door in the center of each wall, which seems to lead to somewhere else.
Besides myself, there were five people in the room, three women and two men.
Meng Nan rubbed his forehead and stood up.
The biggest question now is, who are you? Why are you here? What should you do next?
While Meng Nan was deep in thought, the other people woke up one after another.
Meng Nan found that each of them was wearing the same gray clothes, which looked like prison uniforms.
At the same time, a name was stitched on the left chest of each person's clothes.
Based on the name, everyone roughly knows what they are called.
The three women are named Haoyue, Meng Longlong and Cheng Xiao.
Haoyue always gave Meng Nan a familiar feeling, but he couldn't remember anything.
Meng Longlong has a strange name, but she looks very cute. She is a little girl who looks about seventeen or eighteen years old and wears two ponytails.
Cheng Xiao has a good figure, a straight back and looks very capable.
In addition to the three women and Meng Nan, there are two men left, named Gu Lei and Xu Shichang.
Gu Lei is a tall man, about forty years old, with a long scar on his face, and he looks fierce.
Xu Shichang is an old man in his sixties, with a thin figure and a face full of wrinkles.
The most important thing is that everyone has lost their memory at this moment and has no idea how they came here and how they left here.
After some research, Gu Lei came to a door and opened it to reveal another almost identical room.
"Damn it, what the hell is this place!" Gu Lei said as he wanted to crawl over and have a look.
But at this moment, Gu Lei was stopped by Hao Yue.
Although Haoyue lost all her memory, she instinctively felt that this place was very disturbing.
"What are you doing?" Gu Lei glared at Haoyue.
"Be careful." Hao Yue said calmly. Then Hao Yue looked around and found that Cheng Xiao was the only one wearing a pair of high heels.
So Haoyue came to Cheng Xiao, asked for her shoes, then tore off a few small strips from the lower edge of her clothes, gathered them into a rope, and tied them to the heels of her high heels.
Then Haoyue leaned on the door and threw the high heels in her hand into the room.
When the high heels hit the ground, there was no reaction.
"Look, I just said you are making such a fuss..." Gu Lei glanced at Hao Yue impatiently, but before he could finish his words, he heard a crisp sound coming from the room next door.
Immediately afterwards, the walls in the next room quickly moved closer at lightning speed, and they closed together in just a few seconds, directly crushing the high heels into pieces of paper!
"Gulu." Gu Lei swallowed hard. If he had just walked in by himself, he might have died without even knowing it now.
"Delayed gravity mechanism." Meng Nan climbed to the door, looked at the slowly opening walls on both sides, and said in a deep voice: "Any object that stays for more than three seconds will trigger the mechanism, causing the walls on both sides to come closer and eliminate the intruders.
.”
"Do you know this?" Haoyue looked at Meng Nan.
"I don't know, it suddenly appeared in my head." Meng Nan pointed to his head: "It seems that every door here may not be safe."
"Yes." Haoyue nodded.
"Huh?" At this moment, Meng Nan snorted and looked at the edge of the door in confusion.
I saw three three-digit numbers on the edges of the two cubic rooms. I don't know what these represent.
"I feel that this number may be helpful for us to leave here." Meng Nan said: "But, what's the use?"
"What number?" Cheng Xiao walked over and looked at Meng Nan doubtfully.
Meng Nan told Cheng Xiao the number. Cheng Xiao thought for a moment, and then said to the other three people: "Go and see if other doors also have this number."
Gu Lei, Xu Shichang and Meng Longlong looked at each other without saying anything, but quickly walked to the three doors, opened them and took a look.
"Indeed, there are all." Meng Longlong said and told Cheng Xiao the number.
Cheng Xiao closed his eyes slightly, his mind spinning rapidly.
Meng Nan and Hao Yue returned to the room and looked at Cheng Xiao without saying anything to disturb them.
After a while, Cheng Xiao opened his eyes and said, "I understand, these are Descartes coordinates."
"Descartes coordinates?" Meng Nan and others looked at each other: "What is this?"
"Cartesian coordinates are also called the rectangular coordinate system and the oblique coordinate system. It is a general coordinate for locating the position of an object in space. In layman's terms, taking a point as the origin O, establish a coordinate system with three elements: X, Y, and Z.
If a straight line intersects, by expressing the coordinate point of this item, you can directly locate it
The location of this object." Cheng Xiao rubbed his forehead and tried hard to remember: "To give a simple example, take the middle point of my feet as point O, and make three lines across the front and back, left and right, and up and down. Then I
You only need to confirm your distance from point O to determine your location."
"Have you recovered your memory?" Meng Nan looked at Cheng Xiao seriously.
"No." Cheng Xiao shook his head: "It should be the same as you just now. These should be my original memories that appeared with a little guidance."
"Oh. So what is the use of this Cartesian coordinate system?" Hao Yue asked.
"You can judge the orientation and the position." Cheng Xiao said: "Based on these numbers, this place should have 26 rooms on the X-axis. If the whole is also a regular hexahedron, there should be at least 26*26*
26, which is 17,576 rooms.”
"Tens of thousands of rooms?" After hearing Cheng Xiao's words, everyone was stunned.
"Yes, if there are more than 26 on each axis, then the number will continue to increase dramatically." Cheng Xiao rubbed his forehead.
"Wait a minute. If that's the case, there should be a boundary here. If we use the Cartesian coordinate system, can we find the location of the boundary?" Xu Shichang thought.
"Okay." Cheng Xiao nodded.
"Probably not." However, Meng Nan shook his head: "I don't know if you have felt it, but there will be small-scale vibrations here every once in a while, so I guess that we should be in a space that is constantly moving.
.”
"This...if this is the case, it will be difficult." Cheng Xiao said: "If this movement is regular, that's fine. If there is no regularity, then you can only rely on luck."
"Luck? My luck has always been very good!" Menglong said, "Really!"
"What's the use of talking so much? Let me tell you, instead of waiting here forever, why not go around and explore, maybe you can find a way out!" Gu Lei said impatiently.
"This makes sense." Everyone looked at each other and nodded...
