Xu Ran clicked on the touch screen on the table, and a text directly facing him immediately appeared on it: "Task - bring back 3 roses from the 'labyrinth'." Hint – This game is designed to develop the player's spatial memory; Don't try to leave any markers along the way, the system will automatically erase any traces left by the player. ”

Xu Ran moved a position around the circular countertop, and then clicked on the touch screen again, and the text displayed in that paragraph also rotated an angle, or was it re-displayed in front of him, but there was no new content, but it was impossible to determine the orientation of the four doors of this "starting point" according to the text display direction of the touch screen.

Xu Ran randomly selected one of the four gates, and began his 'labyrinth' exploration from here.

When Xu Ran walked to one of the doors, the light in the room gradually dimmed, and when Xu Ran arrived at the door, there was no light in the "starting point" room, Xu Ran opened his spiritual force field space, and the door he was facing automatically opened.

Xu Ran's current mental force field space can already cover the space range of 10 meters around his body, and he has already observed the situation in the space behind the door before he has walked through this door: this is a regular triangle room with a side length of 5 meters, and there is a closed door in the middle of each side of this regular triangle, and the room is empty, and there is nothing else.

Xu Ran did not choose to enter, but came to the other door of this "starting point" room, when Xu Ran arrived at the door, the door also opened automatically, and through his mental standpoint space, the room behind the door was the same size and layout as the room just now, and it was also a regular triangle room with a side length of 5 meters; Xu Ran still didn't enter, but then looked at the space behind the other two doors one by one, and they were all exactly the same size and layout as the triangular room behind the first door.

After observing the situation in the space behind the door at the fourth door, Xu Ran directly chose to enter, and as Xu Ran entered, the door behind him also closed.

Xu Ran's current spiritual force field space already has a strong penetrating force, like that kind of concrete wall in reality, Xu Ran's spiritual force field can penetrate to a depth of 200 mm; But in this room, even though the wall thickness was only 100 mm, Xu Ran couldn't observe the situation in the next space, and the door of that room was thinner, and his spiritual force field space still couldn't penetrate the door panel.

The triangular room he is entering now, the three walls of the room and the doors are the same in appearance, and there is no difference at all, if it is not prompted, the system will automatically erase all traces left by the player. Xu Ran will find a way to make a mark from the beginning of this room, such as placing a game currency on the ground or something.

But now that he knew that it was futile to make a mark, and understood the purpose of the dream game, Xu Ran concentrated on how to memorize the path along the way.

This time, Xu Ran took the position of the passage door against his back as a benchmark, and first came to the door on the wall on his right, the door opened automatically, and behind the door was a regular triangle room with a side length of 5 meters, and its form was exactly the same as the regular triangle room where he was.

After observing for a while, Xu Ran still did not choose to enter, but came to the other wall of the triangle room where he was, he wanted to see what the shape of the room behind that wall was, so as to find some objective laws and help him remember.

After the door on this wall opened, Xu Ran saw a square room with a side length of 5 meters, compared to the "starting point" room where he stayed at the beginning, except for the lack of the round table and the display screen on it, the rest of the shape, size and structure were exactly the same.

In order to better understand the rules, Xu Ran did not enter this room, but chose to retreat to the "starting point" room, and entered the regular triangle room behind the doors of the other three rooms one by one, and observed the situation behind the other two walls of those regular triangle rooms. Regardless of which triangular room you enter next to it, the room behind the door on the right-hand side of the room is also a triangle, which forms a diamond shape with the triangular room in front of it, and the room behind the door on the left hand side is a square room. ”

After finding this pattern, Xu Ran chose to enter the square room at hand in the triangular room that he entered last, next to the "starting point" room; This square room is a second square room compared to the "starting point" room; Xu Ran came to the other three doors in this room in turn, and the results behind the doors were all the same, and they were all very strange and regular, all of them were exactly the same as the regular triangle rooms he had encountered before.

However, in these identical triangular rooms, the situation behind the other two walls is exactly opposite to the situation corresponding to the regular triangle room adjacent to the "starting point" room, where no matter which regular triangle room you enter, the right triangle is behind the door on the left hand side after entering, and it and the regular triangle room in front of it can also form a diamond-shaped shape; The room behind the right-hand door is a square room.

Xu Ran then probed the other three square rooms that belonged to the second circle room one by one, and found that the back of each door of each of these square rooms was still a regular triangle room, but in these rooms that also belonged to the second circle, the situation behind the other two doors of the corresponding regular triangle room was the same, and it was exactly opposite to the situation behind the other two doors of the first regular triangle room.

At this point, Xu Ran felt that he had discovered some rules: "There are two forms of rooms, one is a square with a side length of 5 meters, and the other is a regular triangle with a side length of 5 meters. Behind each square door is a regular triangle. ”

After further investigation, Xu Ran discovered: "Compared with the 'starting point' room, the room in the regular triangle of the odd-numbered circle, the room behind the door on the right-hand side after entering is a regular triangle, and it can form a diamond-shaped shape with the regular triangle room in front of it, and the room behind the door on the left hand side after entering is a square room. For a regular triangle room in an even-numbered circle, the correct triangle is formed after the door on the left hand side of the room after entering, and it can form a diamond shape with the regular triangle room immediately in front of it; The room behind the right-hand door is a square room. ”

In reality, Xu Ran has not paid attention to the splicing of geometric figures, and now in the dream game, through the current observation, he feels that this kind of square and triangle splicing pattern really has an artistic beauty, and there are rules to follow; He felt that in the future, he really needed to pay attention to the study of the spliced composition of those geometric figures, and he also realized that this "labyrinth" should be the same as the "pyramid", and the further it goes, the more difficult it will be, and the composition of the geometric figures will become more complex.

Now that he has discovered the universal law, Xu Ran is to explore step by step to the depth away from the "starting point" room, the first is to find the "three roses" required by the task, and the second is to ensure that he can always remember the path back to the "starting point" room, after all, to be able to return to the "starting point" room from anywhere is the primary purpose of this training.

So in Xu Ran's next search process, every time he entered a new room, he had to repeat in his mind the way he had come from the "starting point" room, and for those rooms close to the "starting point" room, the process of memorizing the route in his mind was simple and easy; The farther away the room, the more tedious and complicated the process of memorization in his mind; After repeating this process a few times, Xu Ran understood that he didn't know how high this kind of training could improve his memory, but this training method was definitely good for improving his memory, and he felt that this training method should also work for ordinary people in the real world.

Xu Ran didn't know how big this maze was, because the task didn't require it to be completed on the same day, so Xu Ran decided not to explore too far at the beginning according to his ability, so as not to be unable to touch it back; He decided to use the square room in the sixth circle as his initial depth of exploration, and if he couldn't find the three roses, then he would continue to explore new and deeper places.

(This chapter is a bit of a twist, but because it involves the development of mental abilities later, the author feels that it is still necessary to describe it at the beginning, and it will not be so verbose on similar issues in the future.) I had already finished writing it last night, but when I reviewed the combination of the triangle and the square, I found that I had summarized the rules wrong, and hurriedly changed it; After the change, I carefully compared the graphics and pondered it, but there were still mistakes, so I re-brushed it again this morning. Interested readers can take a look at the graphics for themselves, which is quite interesting. ）
