Fengyun Chong Miao Piao nodded lightly, motioning for him to follow in the footsteps of the green beads.

The green beads did not walk very fast, and every time they walked a distance, they had to stop for a while and look around.

"She's supposed to be here for the first time. ”

Fengyun watched Green Bead's actions, and gradually had a realization in his heart, and then began to let his eyes follow her gaze.

"Sure enough, there are markers. ”

Soon, Fengyun had a harvest, and he found some marks where Green Bead's gaze rested, and these marks were mostly located in some hidden places, which were difficult to find.

If it weren't for the guidance of the green beads, Fengyun thought that it would be very difficult to find them, and even if he discovered their existence, he would not be able to parse the information they represented.

This is not surprising to Fengyun.

For the sake of secrecy, under normal circumstances, the agreed ciphers are special, and it is difficult for outsiders to guess the information contained in them.

Fortunately, Fengyun didn't have to bother to decipher what those marks meant, as long as he followed the green beads.

After about half an hour, the three of them finally stopped in front of a rock wall.

The rock wall is located in a valley, and the access to the valley is very hidden, and at the beginning it is just a gap between the rocks, covered with stones and weeds, and mixed with thorns.

Don't say it's a human, even a brute won't get into it casually.

After entering the valley through a narrow and cramped passage, you are greeted by a lush greenery, and the whole valley is full of weeds, trees and vines, giving the impression that there is nowhere to stay.

After the green bead who led the way in front of her head entered the valley, she couldn't help but be stunned for a moment, as if she didn't expect the valley to be like this.

But she soon regained her normal and began to look at the valley, and soon she was heading for a shallow stream.

The plants next to the creek are so lush that they look like city walls.

In Fengyun and Miao Piao's opinion, even if they had to cross the valley, it was definitely not a good choice to walk along the stream, but they didn't say anything, just glanced at each other and followed.

When she reached the creek, Green Bead set her hands to separate the dense plants, and then Fengyun realized that she had indeed made the right choice.

The plants at the creek were indeed denser than in the rest of the valley, but that was only the part he saw, and when he separated the plants a little, it suddenly opened up in front of him.

In front of them, a passage appeared, and although there were some plants, it did not form an obstacle, and they could easily move forward.

Fengyun looked at it and easily found the reason why there were not many plants in the stream, it turned out that there were hard rocks on both sides of the stream, and the plants could not grow like roots.

After walking about five or six hundred meters along the stream, the path was blocked by a rock wall, and we reached the bottom of the valley.

At this point, the stream did not stop, it burrowed into the bottom of the rock wall, where there was a crack.

After reaching the rock wall, Fengyun instinctively paid attention to the crevice that swallowed the stream, and he subconsciously used it as a passage through the rock wall.

However, he quickly dismissed the idea that it was a passageway.

The crevasse was so narrow that only a fist could barely be put in, and even if the green bead was relatively small, it was impossible to get through it.

The crevices are not passages, so the passages are only possible on the rock face.

Green Bead's actions also confirmed Fengyun's suspicions, and she reached out her hands and lifted the curtain-like vines that covered the rock wall.

It's just that to Fengyun's surprise, he didn't see any traces of the passage on the rock wall, and it was impossible for him to be wrong with his eyesight.

Due to the flow of water flowing through the rock wall, there is abundant water vapor, and a layer of green moss grows on the rock wall, but it is also because of the presence of moss, if there is a passage on the rock wall, it can be seen more clearly.

The meaning of the existence of the passage is passage, and as the so-called goose passing through the phonograph, if there is a passage on the rock wall, it should leave traces of being used.

"Is there really no passage in the rock face?"

Finding nothing on the rock wall, Fengyun couldn't help but start to be suspicious, because he remembered the roads he had walked before, and they didn't look like people had walked before.

"Knock Knock ......"

Just as Fengyun thought this, Green Bead made a new move, raised his fist, and began to tap on the rock wall.

Seeing Lu Zhu's actions, Miao Piao was about to go up to help, but was stopped by Fengyun with his eyes.

The green bead striking the rock wall may be a code.

If Miao Piao makes a move, it is very likely to have a bad impact on Green Bead, and it is more likely to arouse the suspicion of the person that Green Bead wants to contact.

Once the other party is really suspicious, the problem can be serious, and their lives will even be in danger.

The passage is set up so hidden, naturally I don't want people to know, and in order to protect the passage, it is not impossible to kill the people who find it.

But soon found out that Fengyun found that he was thinking too much.

The green beads hitting the rock wall have no pattern at all, and they are not concentrated in one place, but they are beaten everywhere on the rock wall.

"Green Bead, do you need my help?"

Seeing that the green beads were hard to knock, Fengyun offered to help, of course, he also wanted to save time.

His mind had changed now, and perhaps the reinforcements he was looking for weren't the same as he had deduced.

They may be closer to Rock City, but it may not be easy to meet them.

"Thank you, Uncle Yun. ”

Lu Zhu did not refuse, but instead cast a grateful look at him.

"I'm here to help, too. ”

Miao Piao also chose to volunteer.

"Thank you, Brother Drift. ”

Lu Zhu sent a sweet smile to Miao Piao.

There are many people and great power, and the three of them worked together, and soon they made a discovery, which was discovered by Fengyun.

Fengyun was able to make the first discovery, not because he was lucky, but because he used the means, he called on the forces of nature and covered them on the rock wall.

Pay attention to the changes in the forces of nature while striking the rock wall, and there is a difference between the vibrations generated by the rock wall and the rock wall itself.

Finding something abnormal, Miao Piao pulled out his knife and took the initiative to clean up the rock wall, scraping off the moss attached to it.

Without the moss, the traces of the passage were finally revealed, a regular rectangle, about six feet tall and three feet wide.

Miao Piao was about to push it with her hand, but was stopped by the green bead, and then she took out something in her arms, a long object with a hook-like structure at the front end.
