For those rooms that are closer to the "starting point", Xu Ran is also able to clear his mind, and he can establish a clear plan composition of the room in the area in his mind; But when he entered the room that was the sixth circle away from the "starting point" room, Xu Ran already felt that the information that needed to be memorized and processed was too complicated, and he could no longer establish a clear room plan composition in his mind.

Xu Ran felt that his way of exploring the maze by rote memorization should not be right; After all, the two geometric figures I am facing now are simple and can have rules to follow, but when I am faced with a puzzle of complex geometric figures, or when I can't find a pattern in the puzzle of geometric figures, this method is completely meaningless.

Of course, Xu Ran did not completely deny this kind of law that could be found, of course he admitted that this kind of regularity has considerable reference value for exploring the maze, but he felt that he should find a more generally applicable way to deal with the challenges of various mazes.

With this thought, Xu Ran took advantage of this clear mind, and he retreated to the "starting point" room the same way.

After thinking about it for a while, he decided on a new way of thinking he should take to explore the labyrinth.

In Xu Ran's current mind, relative to the "starting point" room, including all the rooms in the area of the square room in the fourth circle, he was able to establish a clear plane composition, and he decided to always keep the memory of the plane position of all the rooms in the area of the square room in the fourth circle in the next exploration process, and not add new room graphic memory, so as not to affect his memory when the amount of information is too large.

The purpose of maintaining this "basic memory interval" is also so that he can use it as a reference to establish a useful coordinate system; Xu Ran took the center point of the "starting point" room as the pole, and established a "polar coordinate system" within this "basic memory interval" in his mind, and he established the polar axis of this polar coordinate system from the pole to the midpoint of a certain door in the "starting point" room, so that the polar angles of the midpoints of the other three doors were 90 degrees, 180 degrees and 270 degrees respectively.

Next, Xu Ran's steps to do are simple, he only needs to remember not to let the direction of the polar coordinate system calibrated in his mind change, whenever he needs to change the direction of his walking, he will directly mark the direction conversion angle in his mind, and the transformation angle of this steering relative to the polar axis can be estimated more accurately in his mental force field space.

After establishing this system, Xu Ran's exploration of exercising his memory in the maze was transformed into "firmly maintaining his polar coordinate system, and every time he entered and exited the labyrinth room, the corresponding direction and room type were marked." ”

As long as he can remember this information, he can guarantee: "First, he can return to the starting point the way he came; Second, you can also make sure that you know which rooms have been explored and which ones have not. ”

I want to explain here that the polar coordinate system that Xu Ran established in his mind is just a virtual concept, and it is not like in the holographic recorder, which can be directly calibrated and handed over to the holographic recorder to help him remember; Whenever there is new information that needs to be added, it is not that the polar coordinate system will automatically enter the information, but Xu Ran needs to add information to it at any time, and he must always remember the information that has changed, and the order of change, which is a test of memory.

This is a bit similar to our double-up, when a few rounds of cards are played, the good player will always pay attention to which cards have been played, what cards are left outside, and if they want to throw cards, there are cards outside that are not in position; A skilled player can remember what cards have been played in each round, and this is a game of memory; This kind of memory is one of the talents, and at the same time, when playing cards, always have to remember the cards that you are interested in, both of which are indispensable.

Xu Ran now uses this method of memorizing in his mind at all times to exercise his memory of the labyrinth environment, at first due to discomfort, he walked slowly, and after confirming that his mind had completed the polar coordinate composition of the current process, he continued to move to the next room.

But even so, he only explored the square room of the fifth circle for the first day and a half, and when the room in the sixth circle had not been properly explored, he was told by the system that it was time to go offline.

And the reason why the scope of exploration is not very large is because Xu Ran often in the process of exploration, because his brain cannot maintain the stable operation of the virtual polar coordinate system, so he can only return to the "starting point" room and start again.

During this half day, Xu Ran found a rose, and when he quit the game, the rose was placed on the circular countertop in the "starting point" room.

After landing on the dream game again on the afternoon of November 1st, Xu Ran went to the "Spiritual Power Imperial Object" space first, one because practicing the basic exercises of "Spiritual Power Imperial Object" is his current top priority, and it is put in the first place; Again, he wanted to see if he still met the conditions for using the "Labyrinth", a cultivation treasure weapon, when the spiritual force field value dropped to 20.

After experimental verification, when the mental force field value drops to 20, the "maze" can still be used; After that, every time Xu Ran logged in to the dream game, he went to the "Spiritual Power Imperial Object" space first, and only after practicing the "Spiritual Power Imperial Object" there for an hour did he then go to the "maze" to practice his memory.

He uses the "maze", not necessarily to complete the "maze" rose task, after all, that task does not say that there is a reward, just a way to exercise memory incentives, and as long as he achieves the purpose of exercising mental power in it, it can be regarded as meeting his own requirements.

After Xu Ran entered the "labyrinth" for the second time, the task given to him by the touch screen was still "bring back 3 roses", Xu Ran understood that this was a new start of the task, and the roses he retrieved before no longer counted.

In the second maze live game activity, although the time was reduced by almost 1/4 compared to the first time, Xu Ran still explored the square room of the fifth circle, compared with before, Xu Ran felt that his virtual polar coordinate system was running a lot more stable, although there was still a situation where the mind was suddenly confused, and he was not sure how to stabilize the polar coordinate system he had established, and he needed to go back to the "starting point" room to start again, but compared to the first time, at least the success rate was improved.

Before entering the "labyrinth" for the second time, Xu Ran had checked the "puzzle of a combination of a triangle and a square" on the Internet, and it was indeed the same as the pattern he had detected in the game the first day, but that combination could be infinitely expanded, and it was impossible for him to memorize such a figure himself; And to go through that regularity in the game step by step, the more you go outward, the more complicated the steps are, far less simple than the method you are currently practicing; Moreover, when he got used to this way of memorizing, he could face other kinds of maze shapes and deal with them calmly, and Xu Ran now believed that the practice method he chose was definitely correct.

In the next few labyrinth explorations, he could feel that his polar coordinate system memory ability was gradually increasing, and each time in about 3 hours of maze exploration activities, the scope of exploration that he had memorized in the polar coordinate system was gradually expanding, and by November 4, he had the ability to explore and mark the square room of the seventh circle, and in the seventh circle, he could already find two roses.

After logging into the game on the night of November 4th, his personal information changed again: Mental Force Field: 21; Mental Power: 84 (was 83); Stamina: 21; Field energy: 210.

The long-lost situation of no longer increasing mental power, after 20 days of stagnation and 40 game times, has risen by another value, at least this is a harbinger of breaking through the bottleneck of mental power; The appearance of this information made Xu Ran happy.

When I entered the "Spiritual Power Imperial Object" space that night to practice, the white feather that was placed on the table and was always motionless would occasionally move a little; Although he didn't have the ability to use his spiritual power to make the white feather float in the air, this also greatly increased Xu Ran's confidence and made him feel more happy; At least it gave him hope for success, after all, he already had a clue;

This time, when practicing the basic exercises of "Spiritual Power Imperial Objects", Xu Ran had a new feeling more than before: when exercising now, although the breath in the body is still not smooth, it is better than the previous completely unobstructed, and sometimes it will be unintentionally and stumbling through; And when that white feather was moved, Xu Ran could feel that at that moment, the concentration of the spiritual force field in that area was indeed enhanced, and then the field strength of the entire spiritual force field space tended to balance again.
