So, what's the secret here?

Huang Ling said: "No wonder this place is so secluded, it turns out that no living beings have ever come. ”

Huang Shan said: "I have always felt strange. I wouldn't have gotten here without following the road map in my head. ”

"Have you tried?" Huang Ling asked.

"Tried. I also tried a few times deliberately, and once I didn't follow the route map halfway through, and I didn't make it here. Huang Shan said affirmatively.

"That is, you have to follow the road map exactly before you can get here?" Huang Ling asked again.

"Yes, you can't go wrong at all." Huang Shan nodded and said.

Huang Ling asked again, "What about when you go out?" ”

"When you go out, you can go out as you like." Huang Shan said.

What a strange place!

According to Huang Shan, he must lead the way when he comes in, and he must follow the road map in his mind to get here.

In this way, this is now the exclusive territory of Huangshan, and no one else can enter.

Huang Ling said: "According to what you just said, this has become your exclusive territory, if you don't agree not to lead the way, others will not be able to enter." And I'm so sorry for letting you bring so many people in! ”

Huang Shan immediately said: "Master Spirit Emperor, it's not right for you to say that. If it weren't for you, this would be a resting place for me, and that stone would be of no use to me. ”

After a pause, Huang Shan said again: "Now, I can't absorb it either." To ask these brothers to absorb is to make the most of what they have. ”

Huang Ling nodded and said, "I'm relieved that you can think like this!" ”

After a while, Huang Ling said again, "Let's walk around this mound and see what secrets it has." ”

"Okay. I'm also curious, and I've wanted to explore this mound for a long time. Huang Shan said happily.

Huang Ling and Huangshan searched and explored the mound from top to bottom.

Huang Ling not only observed carefully with his eyes, but also released his divine sense to explore seriously.

However, they searched the entire mound up and down, and found nothing out of the ordinary, let alone any secrets.

This makes Huang even stranger!

Huang Ling said: "It's really strange, there is no problem up and down this mound!" ”

Huang Shan said: "Emperor Ling, should we search around the mound again?" ”

"Good. We searched around the mound again to see what was going on. Huang Ling was even more curious and wanted to search more extensively.

In the same way, they searched around the mound round and round, from near to far.

Huang Ling and Huang Shan began to search shortly after dark, and after midnight, it was dawn again.

After a night of searching, both were tired, but found nothing.

By this time, they had come to a place four miles away from the mound.

In other words, after a night of searching, they searched all the places within a radius of four miles around the mound.

However, they still found nothing.

Huang Ling looked at the dawn of the dawn that was about to brighten, and couldn't help but smile bitterly.

This place within a radius of four miles is equivalent to fifty square miles, which is already a large area.

Thinking of this, Huang Ling said, "Forget it! Let's go back to the mound. ”

Huang Shan said, "Okay. I'll lead the way! ”

Huang Ling was stunned for a moment and said, "Don't lead the way." Let me walk around and see if I can get to the mound from here. ”

Huang Shan smiled and said, "Okay." You go ahead and give it a try! ”

Huang Ling looked around and made a few marks on the ground in front of him.

Then he glanced at the mound four miles away, and determined the direction of his progress.

After a night of searching, Huang Ling knew that from here to the mound, it was basically flat, and there were no big ditches or bumps.

He aimed at the mound four miles ahead, and walked straight in the direction of the mound.

Huang Shan followed behind Huang Ling, and also aimed at the mound like Huang Ling, and went straight forward.

According to their expectations, they aimed at the mound and went straight ahead, and the slowest should have reached the mound a quarter of an hour at the earliest.

And so they walked and walked.

After a quarter of an hour, they did not reach the mound, which was still far ahead of them.

Huang Ling took a breath, raised his steps again, and continued to move towards the mound.

Another quarter of an hour passed, and they still did not reach the mound.

But the mound was still a few miles ahead of them.

"Hehe, what a hell!" Huang Ling continued as he spoke.

They walked straight for another quarter of an hour, but the mound seemed to be receding backwards, still so far away from them.

The mound is in front of you, you can see it clearly, but you just can't walk there, what is the situation?

Could it be that this is what kind of two-dimensional space, not in a space?

Huang Ling thought as he walked.

If there is a two-dimensional space here, then how do these two spaces connect and overlap?

Huang Ling remembers that when Huangshan used to lead the way, it took about a quarter of an hour from seeing the mound to walking to the mound.

At dawn, they were about four miles from the mound.

It stands to reason that the four-mile road is easy to walk in a quarter of an hour.

But they had been walking for nearly half an hour, and it seemed that they were still far from the mound.

Huang Ling asked Huang Shan and said, "Brother Huang Shan, do you need to look at the direction of the mound when you follow the road map in your mind?" ”

Huang Shan replied: "You don't need to look at the direction of the mound, you just need to follow the road map in your head." ”

"Tell me how to do it. For example, what do you do when you see a mound in the distance. Huang Ling said to Huang Shan inducingly.

Huang Shan listened to Huang Ling's words and said, "It's actually very simple. When I first saw it, or suddenly looked up and saw the mound in front of me, I started to walk according to the route in my head, regardless of the situation outside, and I no longer looked at the mound in the distance, I just walked according to the route in my mind. ”

"Don't you even look at what's going on under your feet?" Huang Ling asked again.

"When I walk along the path of my mind, the situation under my feet is the same as the situation in my head, there is no difference." Huang Shan explained.

The more Huang Ling listened, the more interesting he became, and said, "Hehehe, it's really interesting! I've seen two-dimensional spaces in the fairy world, but there will be marks where the two spaces meet, and you can find them if you pay a little attention. This is also a two-dimensional space, but the places where they meet are difficult to find. ”

After pausing for a while, Huang Ling said again: "What's even more interesting is that according to what you said, as long as you see the mound, no matter where you are, you can reach it as long as you follow the route in your mind. This is different from the two-dimensional space of the fairy world. ”

Huang Shan listened to it and was amazed by Huang Ling's erudition.

Huang Ling said again: "When you led the way, I found that the path you walked was very distinctive, so I made some records. Now, I don't look at the mound, I walk according to my record and see if I can get to the mound. ”

After Huang Ling finished speaking, he no longer looked towards the mound, but walked forward according to the records he made when Huang Shan led the way.

Huang Shan still followed Huang Ling, and did not look at the mound again, but just followed Huang Ling closely.

Huang Ling walked strictly according to the record, and he always chose a place with dense grass, as if he was following the same trend.

If you walk like this, will you be able to reach the mound?

Huang Ling's heart was full of hope, but also had many doubts.
