Chapter 1223: key

Feng Yun's gaze was naturally attracted by what the green bead took out, and found that its length was close to one foot. In addition to the structure with a hook at the front end, there was also a handle at the end.
As for the material, Feng Yun is very familiar with it, and it is the material used to make stone coins.
Looking at what Lu Zhu took out, Feng Yun showed a confused look.
In his opinion, the function of what she took out should be similar to the key he knew well, but he didn't see any holes in the place where the rock wall was cleared.
"Big Brother Diao, please clean up this place too."
Luzhu took the key and looked at the rock wall in front of him, and suddenly raised his finger to the left side of the cleared part, which was about one foot away from the cleared rectangle.
Miao Piao didn't say anything, and immediately cleaned up at the place designated by Luzhu.
After scraping off a large piece of the table from the rock wall, I finally discovered that it was a long strip of hole, about one finger long, and it was barely wide enough to fit a finger.
The moss at the opening of the small hole was completely removed, and a deep hole appeared.
Lu Zhu walked over immediately, only that the small hole was a little high from the ground, and she barely inserted the "key" in with her toes, the hook went up, and the guard who had reached the end stopped.
Miao Piao was very eye-catching, and immediately moved a stone over and placed it under her feet.
The movement of the green bead did not stop there. After inserting the key into the small hole, he pushed it up with his hand until it reached the top of the small hole. Then he held the handle of the key with his hand and made a gesture to pull it out. .
"Do you want me to help?"
Miao Piao seemed to be worried that Luzhu would not be able to pull, and offered to help.
"Thank you Brother Diao. I can do it myself."
Luzhu declined.
Fengyun was not surprised by this.
Through observing her, if his inference is correct and she is better than ordinary totem warriors in all aspects, her power should not be much weaker than Miao.
In other words, if her strength is not enough, it would be useless to change to Miao Piao.
However, he is more inclined to pull the key without much effort.
Lu Zhu's subsequent performance also confirmed Feng Yun's guess, she just pulled the key out half way.
Of course, the so-called lightness is only relative to Luzhu. It is impossible for an ordinary person to pull the slightest even with the strength of breastfeeding.
"Boom..."
Just the next second after Lvzhu pulled out the key, Fengyun heard a dull sound, faintly coming from the rock wall.
At the same time, Feng Yun felt a tremor from the bottom of his feet, which made him understand that the weight of what fell on the ground was definitely not light.
Lv Zhu did not show any abnormality about this, and pushed the key in his hand inward, moved it under the hole, pulled it out directly, and put it back in his arms.
She turned her head to look at Miao Piao, pointed to the rectangle on the rock wall, and said, "Big Brother Piao, please push it there."
"okay."
Miao Piao showed a face of sudden realization and walked over quickly.
He was originally wondering why there was no passage on the rock wall after Lu Zhu used the key.
"Crunchy..."
Accompanied by a harsh rubbing sound, the long direction on the rock wall began to sink into the rock wall.
It can be seen from Miao Piao's expression that the muscles on his cheeks tightened with a lot of effort.
He is an advanced totem warrior, and he has to work so hard. It can be seen that the pushing stone is definitely not small.
In fact, it was the same. He pushed inward about one foot and five feet deep, before it suddenly disappeared from his eyes and fell down.
"Ahem..."
The dust splashed after the boulder hit the ground made Miao Piao cough, but he still didn't come back, waving his hand to drive away the dust, and looking inside.
Soon he uttered a voice and shouted, "Brother Yun, Luzhu, there is a passage inside."
In fact, he didn't need to say anything, Miao Piao could see the situation behind the passage clearly, because it was not dark inside, and white light was faintly transmitted.
With Fengyun's vision, not to mention that there is light, even if it is pitch black, he can also see very clearly.
Behind the passage is a long corridor with obvious traces of artificial excavation. As for where it leads, Fengyun is not clear.
The tunnel is not straight, his eyesight is good, but he cannot turn.
"Uncle Yun, let's go in together."
Luzhu also looked into the passage, then turned to look at Fengyun.
"Okay. You go in first. I am behind."
Although Feng Yun didn't think they would be followed, he still decided to be more careful and did the finishing touches.
After the green beads entered the passage, Fengyun began to clear the traces they left behind. First, the stone that Miao Piao had moved to give Lvzhu's footsteps was put back in the distance, and then the moss scraped from the rock wall was thrown into the stream, so that they rushed into the deep cracks with the stream.
Feng Yun also completely removed the footprints left by the group of three people.
Finally, he checked again before stepping into the passage.
As for the passage itself, it is covered by dense vines, and it is not easy to find it.
When Fengyun saw Miao Piao and Lu Zhu, Lu Zhu was okay, and Miao Piao was already a little impatient.
Feng Yun ignored Miao Piao's impatience and began to look around. He was still curious about the way to seal the passage.
He found that the structure was really delicate. What was hooked out by the green bead's key was a long strip of stone. Its function was similar to a tenon and tenon joint. Although it did not bear much strength, its function was very crucial.
It is precisely because of its existence that it can be ensured that the boulder that blocked the passage is locked, and it is almost impossible to push the boulder without pulling it out.
Almost is used here for the sake of rigor.
If the person pushing it is a very high-level totem warrior, it’s a different matter, because with his ability, there is no channel on the rock wall, and he can’t stop him at all. He can relax on the rock wall by himself. A channel was dug out.
Fengyun took action and put the huge stone blocking the passage back to its original position, and the stone that was pulled out by the green bead with the key also returned.
The group of three began to walk along the passage.
The passage is very long, and it took a full two hours to reach the end.
Although walking in the passage is not like traveling on the ground, because the passage is relatively wide and the cleaning is relatively clean, the speed is not slow.
According to Fengyun’s estimates, even the most conservative number, the length of the channel exceeds one hundred miles.
Seeing that they were about to leave the passage, the three of them couldn't help speeding up, but they could not get out of the passage as they wished, and they were stopped.
