Fengyun's gaze was naturally drawn to what the green bead had taken out, and he found that it was nearly a foot long, and in addition to a hook structure at the front, there was a handle at the end.

As for the material, Fengyun is very familiar with it, and it is the material from which the stone coins are made.

Looking at what Green Bead took out, Fengyun showed a look of confusion.

It seemed to him that the things she had taken out should have a function similar to the keys he knew, but he didn't see any holes in the rock walls where they had been cleared.

"Brother Drift, please clear this place too. ”

Midori took the key and looked at the rock wall in front of him, and suddenly raised his hand and pointed to the left side of the cleared part, which was about a foot away from the cleared rectangle.

Miao Piao didn't say anything, and immediately cleaned up in the place designated by the green bead.

After scraping off a large piece of the table in the rock wall, it was finally discovered that it was a long hole, about a finger long and barely wide enough to fit into a finger.

The moss at the opening of the hole was completely removed, and a deep hole appeared.

Green Bead immediately walked over, but the small hole was a little high from the ground, and he barely inserted the "key" into it on tiptoe, and the hook went up, until the guard at the end stopped.

Miao Piao had a good eye, and immediately moved a stone and placed it under her feet.

After inserting the key into the hole, he pushed it up with his hand until it reached the top of the hole, and then he grabbed 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 Lu Zhu would not be able to pull it, so she offered to help.

"Thank you, Brother Drift. I'll do it myself. ”

Midori declined.

In this regard, Fengyun was not surprised.

Through his observation of her, if his inference was correct, she was better than ordinary totem warriors in all aspects, her strength should not be much weaker than Miao Piao.

In other words, if her strength is not enough, it will be replaced by Miao Piao, which will also be in vain.

However, he prefers to pull the key, which doesn't require much force.

Green Bead's next performance also confirmed Fengyun's guess, she just pulled it out slightly, and pulled the key out halfway.

Of course, the so-called light is only relative to the green beads, and if you are an ordinary person, it is impossible to pull a single inch even if you use the strength to eat.

"Knock ......"

The next second that Green Bead pulled out the key, Fengyun heard a dull sound, faintly coming from the rock wall.

At the same time, Fengyun felt a tremor coming from the soles of his feet, making him understand that the weight of what fell on the ground was definitely not light.

Green Bead didn't show any abnormality about this, pushed the key in his hand inside, moved it to the bottom of the hole, pulled it out directly, and put it back into his arms.

She turned her head to look at Miao Piao, pointed to the rectangle on the rock wall, and said, "Brother Piao, please push it there." ”

"Okay. ”

Miao Piao showed an expression of sudden realization and walked over quickly.

He had wondered why there was no passage on the rock wall after the green bead had used the key.

"Crunch ......"

With a harsh grinding sound, the long direction of the rock wall began to sink towards the rock wall.

It could be seen from Miao Piao's expression that he used a lot of strength, and the muscles on his cheeks were tense.

He is a high-level totem warrior, and he has to work so hard, so it can be seen that the stone he is pushing is definitely not small.

In fact, he pushed about a foot and a half foot deep into it before it suddenly disappeared from his eyes and fell.

"Ahem......"

The dust splashed after the boulder hit the ground made Miao cough, but he still didn't retreat, waving his hand to drive away the dust while looking inside.

Soon he made a voice and shouted, "Brother Yun, Green Bead, there is a passage inside." ”

In fact, there was no need for him to say it at all, Miao Piao could see the situation behind the passage clearly, because it was not dark inside, and there was a faint white light shining through.

With Fengyun's eyesight, 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, and it is not clear where it leads.

The road is not straight, his eyesight is good, but he cannot turn a corner.

"Uncle Yun, let's go in together. ”

Green Bead also looked into the passage, and then turned to look at Fengyun.

"Okay. You go in first. I'm in the back. ”

Although Fengyun didn't think they would be followed, he decided to be careful and did the finishing job.

After the green orb entered the passage, Fengyun began to clear the traces they had left behind. First, he put the stone that Miao Piao had moved to cushion the green beads back into the distance, and then threw the moss scraped off the rock wall into the stream, allowing them to rush into the deep rock crevice with the stream.

Fengyun completely cleared the footprints left by the three of them.

Finally, he checked it again before stepping into the passage.

As for the passage itself, it is covered by dense vines, and it is not easy to spot.

By the time Fengyun saw Miao Piao and Green Bead, Green Bead was fine, and Miao Drift was already a little impatient.

Fengyun ignored Miao Piao's impatience and began to look around, he was still a little curious about the way to seal the passage.

He found that the structure was indeed more exquisite, and the key of the green bead hooked out was a long strip of stone, which acted like a mortise and tenon joint, although it did not bear much force, but the role was very crucial.

Because of its presence, it was possible to ensure that the boulder blocking the passage was locked, and it was almost impossible to push the boulder without pulling it out.

Almost is used here for the sake of rigor.

If the person pushing it was a very high-level totem warrior, it would be a different matter, because with his ability, there was no passage on the rock wall, and he could not stop him at all, and he could easily carve out a passage in the rock wall by himself.

With Fengyun's action, the boulder blocking the passage was put back in its place, and the stone that had been pulled out by the green bead with a key was also put back in place.

A group of three began to walk along the passage.

The passage was very long, and it took two hours to reach the end.

Although walking in the passage is not like walking on the ground, the speed is not slow because the passage is relatively wide and clean.

According to Fengyun's estimates, even the most conservative figures are more than a hundred miles long.

Seeing that they were about to leave the passage, the three of them couldn't help but quicken their pace, but they were not able to get out of the passage as they wished, and they were stopped.
