At this moment, the sky has turned dark, and Xu Huange and Ye Mujin have been wandering around a pond rock for a long time according to the guidance of Du Wei.

"What about after the lieutenant said to turn right?"

"I don't know, he didn't seem to finish his sentence before he came. Xu Huange hid in the rock wall of the pool and looked to the right.

"Then we can't keep wandering around this pond rock, sooner or later we will be discovered by the patrol people here. Ye Mu Jin looked through the gap in the pond rock and saw a group of patrols walking outside.

"Is turning right further?" As the sky got darker and darker, Xu Huange squinted his eyes, unable to see ahead clearly, and he felt the "eye" on the back of his left hand begin to itch again. He looked at the eye in his left hand and saw that it glowed reddish again.

"Why is there light on the back of your hand?" asked Sumire Yemu.

Xu Huange covered it up with an evil shirt. "Nothing. ”

"Who?" shouted a group of inspectors.

"Oh no! I've been discovered!" Suddenly, a long arrow shot in front of Ye Mu Sumire.

"Jump into the pool! Hurry!" Xu Huange grabbed Ye Mujin's arm and exhaled and jumped into the pool together.

The two sank into the pool, the black pool water was not as muddy as expected, Xu Huange slowly opened his eyes, and saw the shadows of a group of patrols above his head, he didn't dare to exhale, and pulled Ye Mujin to swim into the depths of the pool together.

The inside of this pond rock is crisscrossed, the depth of the pond is bottomless, and there are some spiky plants growing inside the pond rock, and a blood mark immediately appears on the human face. Xu Huange and Ye Mu Jin slowly wandered along the pond rocks, passing one cave rock after another, but the more they went inside, the darker it became.

Xu Huange took out the smoked beads from his pocket and silently recited the smoked beads rune, which glowed with a faint light, illuminating the rock wall in front of him.

"Huange, I can't do it anymore, I don't have the strength anymore. I don't know how long I swam inside, Ye Mu Jin's wheezing sound became heavier and heavier.

In fact, Xu Huange was also exhausted at this time, except for eating a meal in the palace prison during the day, he didn't even drink saliva until now, and his stomach was also rumbling with hunger.

As they swam deeper, the more they felt that the strange atmosphere inside this pond rock became more and more intense.

"Something is wrong. Xu Huange said with a frown.

"What's wrong?"

"When we swam here just now, there were a lot of aquatic plants on the rock wall, and some insects chirping, but now you don't notice, the deeper you go, the more silent it becomes, there is not even moss growing on this side of the rock wall, there is no sign of life. Xu Huange held a stream of pond water in his hand, and under the illumination of the smoked beads, it was glowing with silver light.

"You mean it's backwater?" asked Sumire Yemu.

"Not necessarily, it can be contaminated by something. ”

"So what do we do now?"

"Let's swim forward, if that's still the case, we'll have to go back the way we came. ”

The front turned slightly brighter, Xu Huange and Ye Mujin went all the way forward, and suddenly two holes appeared in front of them, and the two looked at each other at the same time.

"What should we do? Which cave should we choose?" Ye Mu Sumire looked at the two holes and made a difficulty.

Xu Huange approached the two openings and observed carefully, the inner wall of one cave was damp and there were some water droplets attached to it when he touched it with his hands, while the inner wall of the other larger cave was slightly dry, and there were some traces of dry and cracked soil attached to his hands.

"It's not going to be a dead end, is it?" asked Ye Mu Sumire, touching the wall.

"No, it's brighter than where you first came, there must be an exit. Xu Huange firmly believed. He picked up a handful of small pebbles from the side of the stone wall and threw them at the two holes, pricking up his ears to listen, but there was no response, all of which were bottomless feelings.

"Why don't we split up?" Let's each choose a hole and swim forward, mark the stone wall with circles along the way, count two thousand times in our hearts, and return to meet each other wherever we go?" Xu Huange proposed.

"Great idea!"

The two acted separately, Xu Huange chose a hole with water droplets attached, and Ye Mujin chose to dry some slightly larger holes.

Xu Huange made a mark next to the stone wall with stones every five meters, and when he made the eighth mark, four more holes appeared in front of him, and at this moment he realized that separating from Ye Mu Jin seemed to be a wrong choice.

He decided to take a gamble. So he chose to swim through the second hole from left to right, and marked the outside of the hole. When he swam into it to make the fourth mark, he had already swam out of the hole, but the sight before him blinded him, and eight holes appeared around him!

The entrance to the cave here seems to increase in the nth power, and the more you swim to the back, the more open and bright it becomes. He couldn't swim any further, and at this time, the time to return agreed with Ye Mu Jin had also arrived, and he decided to return the same way to join Ye Mu Jin.

He swam back to the original cave, following the markers he had made along the way, and after a while he faintly heard the sound of water in front of him.

"Who's in front? Is it Hwange?"

It's Sumire's voice. "Mu Jin, it's me!"

"Huh, thank God, I actually ran into you!" Ye Mujin hurriedly swam over, "You don't know, I swam into that hole, and suddenly four more holes appeared!"

"Me too, I just swam out and found eight more holes, and I'm returning the way I came to meet you, and I'm lucky to have met you here. How did you find me?" asked Xu Huange.

"I didn't know that when I came across four holes, I randomly chose one of them and swam out and bumped into you. ”

"So, no matter which hole you enter, you will come in the same place. ”

"So what now?" asked Sumire Yemu.

"Since they will all converge on the same road, let's swim in the direction of the cave at the meeting point and then figure out a way. ”

Xu Huange and Ye Mu Jin swam forward together, and came to the eight cave entrances again.

"There are eight more holes, and according to this trend, if we swim further, there may be sixteen or more holes. Ye Mu Jin said.

"Yes, the entrance to the cave is definitely not an exit, it will only sink deeper and deeper. Xu Huan said.

Ye Mu Jin swam to the middle of the major cave entrances, looked up at the faintly shiny rock wall, and said, "I have seen this layout in ancient books, similar to the pattern of "Bapu", the inner wall is damp, the pool water is flooded, the entrance of the cave increases, and the pool water gradually deepens. ”

"The location of Puzhong? There is no bottom here, there is no top of the head, we can't know how many holes are the midpoint, if we explore them one by one, we may die here. Xu Huange looked up and saw a faint white light, but he couldn't see what was on the top floor, like a layer of white fog shrouded here.

"Mu Jin, can you tell what's on it?" Xu Huange pointed upward.

"I couldn't see what it was, it was like a thick cloud of mist. Ye Mu Sumire replied.

Xu Huange looked around, the rock wall has been surrounded by the cave entrance, and the bottom of the pool is even more unfathomable, if you look for the location of Puzhong from the cave, I am afraid that I will starve to death in the cave before I can find it. Xu Huange looked up along the surrounding rock walls, although the rock walls were steep and wet, but they were concave and convex, and they also had certain climbing conditions. Since there is no way out left and right, why not explore upwards?

"Mu Jin, do you know how to climb rocks?" asked Xu Huange as he touched the rock wall.
