"Whew!"

Ling Ruo screamed, and Li Weitian hurriedly moved his feet away with a weak heart. Just now Ling Ruo stopped there thinking about something, Li Weitian continued to go down, but accidentally stepped on her head.

If the two of them weren't like geckos on the cave wall now, Ling Ruo swore that she would definitely jump up and hit the stinky man's dog head with a few big bangs!

"Y-Are you alright?" The man asked with little confidence, and quickly crawled up to her, carefully helping her pat her hair off the mud from the soles of his shoes.

Ling Ruo kicked the tight fleshy part of the man's back fiercely, and only after letting out a vicious breath did he say, "Do you remember what we said about time after passing through the white mist when we entered the secret realm? ”

The man's face became serious, "Remember, there is an illusion of time in the white mist. You're saying that the hole isn't really that deep, but it just feels unfathomable? ”

Ling Ruo said uncertainly, "You think, we've been climbing down for so long, it feels like we've walked down for at least ten miles. There are Li Liankun and Li Feng in front of us, and there are the two tricks of the Yin family in front of them, and there are Yin Pengfei and Xu Ziyun in front of them, and there is He Kong and Xu Hongshan in front of these two people. How deep does this hole have to be? ”

After a pause, she continued: "Also, don't forget, He Kong walked nearly ten miles earlier than Xu Ziyun and them, and even the tendons and ropes were stretched to the limit. ”

Is there really such a deep hole?

"However, our perception may be deceived, but even the tendons are not. After He Kong went down with the tendon rope, it was really tight, and it was impossible to fake this distance. Li Weitian said.

Ling Ruo was right to think about it.

But she suddenly remembered another idea she had said to Xu Ziyun before she entered this cave.

"Could it be, in fact, that the part of our perception that is deceived is not about the depth of the cave, but about the direction? In fact, it is not always vertically downward, it may be like a maze, with twists and turns. It's just that our perception is deceived that we think that we are going all the way down? And in reality, it's possible that we're just stuck in a certain range and going around in circles? ”

Ling Ruo's divine sense, in a sense, is also one of perceptions, but it is beyond the five senses of mortals. Therefore, it will also be deceived and will also produce illusions.

Li Weitian glanced at the endless hole under his feet, frowned and said, "In other words, it is possible that we are not actually climbing down, or we are climbing a slope?" ”

Ling Ruo nodded, "Yes." It is even possible that now the entrance of the cave is horizontal, and we are actually climbing at the top of the cave. ”

As soon as her words fell, a sense of weightlessness hit, and the hand that was originally picking on the hole in the cave wall suddenly loosened, and the whole person fell hard to the opposite cave wall.

That's right, it's the kind of "fall" from top to bottom, her back hits the wall of the hole hard, and her face is dazed.

At this time, in her eyes, she was actually lying on the ground, and Li Weitian, who was originally on the other side of the cave wall, was lying on top of her head.

Li Weitian looked back, in his eyes, Ling Ruo was leaning against the cave wall, he didn't step on any protruding clods of soil under his feet, and he didn't have any potholes in his hands, the whole person seemed to be hanging in the air with his back against the cave wall, he couldn't help but feel numb on his scalp, "You hurry up and grab the cave wall and slide down carefully!" ”

Ling Ruo couldn't help but look at his feet, and a thought uncontrollably arose in his heart: "It turns out that this side is below." ”

The moment she had this thought, her perception also changed, she thought she was lying flat on the cave wall, but now she was standing with her back against the cave wall, and the bottom of the hole was under her feet.

At the moment when her perception changed, she quickly slid down with her back against the cave wall.

Li Weitian was shocked, and hurriedly grabbed the cloud leaf vine on his waist, trying to stop Ling Ruo from continuing to slide down.

However, Ling Ruo reacted quickly, she probably guessed what was going on, and before the cloud leaf vine around her waist tightened, her figure suddenly stopped, and she just hung her back against the cave wall.

Li Weitian breathed a sigh of relief and slowly climbed down until he was at the same height as Ling Ruo.

Seeing Ling Ruo still standing in the air with his back against the cave wall like just now, Li Weitian only felt that his breath had not been raised, and his lips trembled: "You ......"

However, an even stranger scene happened.

Ling Ruo smiled at him, bent his legs, and the soles of his feet that were originally volleyed were attached to the cave wall, and the whole person slowly stood up.

At this time, in his eyes, Ling Ruo was stepping on the cave wall, and the whole person was in the air.

"Did you practice spider skills? Can you walk on a wall? ”

Ling Ruo was so angry by his words that he almost didn't maintain his figure and fell. She took a deep breath, pointed to her head, and said, "Control your own perception, Li Weitian." Don't look at me, try to imagine that I'm not on the wall of the cave, but on the floor. ”

Li Weitian's comprehension ability was not bad, and he immediately guessed the meaning of Ling Ruo's words.

Does this mean that in this cave, the upper and lower directions are not fixed, but adjusted according to each person's cognition?

If he thinks the soles of his feet are "down", then he is in a hole that is vertically downward.

But if he felt that he was lying on his stomach, then the cave wall in front of him was "down", and the cave wall on the side where Ling Ruo was standing was "up", then they were now in a horizontal tunnel.

It's also too ...... It's incredible, but it can explain Ling Ruo's current situation.

Her current appearance was weird and unreasonable in his eyes, but in Ling Ruo's own eyes, it was normal for her to just stand on the ground.

And this is because the directions of "up" and "down" that he and Ling Ruo know are inconsistent.

Li Weitian closed his eyes vigorously, concentrating, and trying to imagine that he was lying on the floor now. After a slight dizziness, he realized that he was really lying on the cave wall.

After exhaling a few deep breaths, Li Weitian tried to stand up like this, and then, just like Ling Ruo, he stood up with his feet on the cave wall. The hole that was originally above his head became his left hand side, and the direction of the bottom of the cave under his feet became his right hand side.

And at this time, Ling Ruo, in his eyes, was hanging upside down on the top of the cave as if there was something hanging on his feet, and he was facing the top of his head. I believe that in Ling Ruo's eyes at this time, he is in the same situation.

Seeing that Li Weitian's body was swaying slightly, Ling Ruo hurriedly reminded him: "Remember, your feet are 'below', and the top of your head is 'above', so as to adjust your cognition, you will not be controlled by this hole and fall into its trap." ”

Li Weitian nodded solemnly and quickly stabilized his figure.

If his cognition is not firm enough, and he still feels that the original direction of the bottom of the cave is "down", then he will soon lose control and fall all the way to the bottom of this endless cave.
