Chapter 1222: Secret

Feng Yun Chong Miao Piao nodded lightly, motioning him to follow Lu Zhu's footsteps.
Lu Zhu didn't walk very fast, and every time he walked a certain distance, he had to stop for a while and look around.
"She should be here for the first time."
Feng Yun saw Lu Zhu's behavior, and gradually had a clear understanding in his heart, and then began to let his eyes follow her.
"Sure enough there is a mark."
Soon, Feng Yun had a harvest. He found some marks in the place where Lu Zhu's gaze stayed. Most of these marks are located in some hidden places, which are difficult to find.
If it were not for the guidance of the green beads, Fengyun would think it would be very difficult to find them. Even if he discovered their existence, he would not be able to parse out the information they represent.
Fengyun was not surprised by this.
For the sake of confidentiality, under normal circumstances, the agreed codes are special, and it is difficult for outsiders to guess the information contained therein.
Fortunately, Fengyun didn't have to bother to decipher what those marks meant, just follow the green beads.
Just walking and stopping like this, after about half an hour, the three 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. The beginning is just a gap between the rocks, full of stones and weeds, and thorns.
Don't say it's human, even brute beasts won't get in casually.
After entering the valley through a narrow and cramped passage, what you see is a lush green. The whole valley is full of weeds, trees and vines, giving people a sense of nowhere to go.
After Lv Zhu, who led the way in front of her, entered the valley, she couldn't help but froze for a moment. It seemed that she hadn't thought of the way inside the valley.
But she quickly returned to normal and began to observe the valley. Soon, she walked towards a shallow stream.
Because of the abundant water supply, the plants beside the creek grew extraordinarily lush and looked like a city wall.
In Fengyun and Miao Piao's eyes, walking along the stream is definitely not a good choice even if they want to cross the valley, but they didn't say anything, just glanced at each other and followed.
Before reaching the stream, Luzhu started to separate the dense plants, and then Fengyun discovered that her choice was indeed correct.
The plants in the creek were indeed denser than the other places in the valley, but that was only the part he saw. After separating the plants a bit, his eyes suddenly opened up.
A passage suddenly appeared in front of them. Although there were some plants, they did not constitute a barrier and could easily move forward.
Fengyun looked at it, and it was easy to find 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 plants seemed to take root and grow.
After walking along the creek for about five or six hundred meters, he was blocked by a rock wall and reached the bottom of the valley.
At this point, the stream did not stop. It drilled in from below the rock wall, where there was a crack.
After reaching the rock wall, Fengyun instinctively paid attention to the rock crack that swallowed the stream, and subconsciously used it as a passage through the rock wall.
But he quickly denied the idea that it was a channel.
The rock gap is very narrow, and only one fist can barely get in. Even if the green ball is relatively small, it is impossible to get in through it.
The rock crack is not a channel, so the channel can only be on the rock wall.
Lvzhu's behavior also confirmed Fengyun's guess. She stretched out her hands and lifted away the curtain-like vines covering the rock wall.
What surprised Fengyun was that he didn't see the traces of the passage on the rock wall, and it was impossible to read it wrong with his eyesight.
Because of the water flowing under the rock wall and abundant water vapor, a layer of green moss grows on the rock wall. However, because of the presence of moss, the rock wall can be seen more clearly if there are channels.
The meaning of the passage is to pass, and as the so-called geese pass by, if there is a passage on the rock wall, it should leave traces of being used.
"Is there really no passage on the rock wall?"
He didn't find it on the rock wall, and Feng Yun couldn't help but start to doubt it, because he remembered the road he had walked before, and it didn't look like someone had walked.
"Boom..."
Just when Fengyun thought this way, Lu Zhu had a new movement, raised his fist, and began to knock on the rock wall.
Seeing Lu Zhu's behavior, Miao Piao was ready to go up and help, but Feng Yun stopped him with his eyes.
The green bead hitting the rock wall may be a kind of secret sign.
If Miao Piao shot, it is likely to have a bad influence on Lu Zhu, and it is more likely to cause suspicion from the person Lu Zhu wants to contact.
Once the other party really has doubts, the problem can become serious, and their lives may even be in danger.
The passage is so concealed that people naturally don’t want to know it. In order to protect the passage, it’s not impossible to kill those who find it.
But soon discovered that Feng Yun found himself thinking too much.
There is no regular pattern when the green beads hit the rock wall, and they are not concentrated in one place, but hit everywhere on the rock wall.
"Luzhu, do you need my help?"
Seeing that Lu Zhu had been struck hard, Feng Yun offered to help, of course, he also wanted to save time.
His current thinking has also changed, and perhaps the reinforcement Lu Zhu wants to find is different from what he inferred.
They may be closer to Rock City, but it may not be easy to meet them.
"Thank you Uncle Yun."
Luzhu did not refuse, but cast a grateful look at him.
"I'll help too."
Miao Piao also chose to volunteer.
"Thank you Brother Diao."
Lu Zhu sent a sweet smile to Miao Piao.
There are so many people and great power. When three of them worked together, they soon discovered it, and Fengyun discovered it.
Feng Yun was the first to discover it, not because he had better luck, but because he used methods. He used the forces of nature to cover them on the rock wall.
While striking the rock wall, pay attention to the changes in the force of nature, and there is a difference between the place where the rock wall passively passes the hand and foot and the vibration generated by the rock wall itself.
After finding the abnormality, Miao Piao drew out the knife and took the initiative to clean up the rock wall, scraping off the moss attached to it.
Without the moss blocking, the traces of the passage were finally revealed. It was a regular rectangle, about six feet high and three feet wide.
Miao Piao was about to push it with her hands, but was stopped by the green beads, and then she took out something in her arms, which was a long object, with a structure similar to a hook on the front end.
