The appearance of bright light obviously means that Chen Hui and his family have seen the exit.

Nine Yan immediately walked in the past, but this hole is too small, nine Yan can only put the head out, even the body can't go out.

Jiuyan first looks at the surroundings outside, then retracts and looks at Chen Hui and Su Yin.

Chen Hui and Su Yin are looking forward to Jiuyan, waiting for Jiuyan to tell them what's going on outside.

Finally came here, saw the exit, in case it is not the top of the holy mountain, it is really in vain.

Fortunately, Jiuyan didn't immediately tell Chen Hui and Su Yin, just to satisfy their appetite, not really can't say.

"It should be the top of the holy mountain!" Nine Yan's face peeped out to promote narrow smile to say.

Hearing Jiuyan's answer, Chen Hui and Su Yin look at each other and see a relieved look on each other's face.

Nine Yan at this time, stretched out a hand to grasp to the edge position of the hole.

The sound of "Pusu" is constantly ringing. Under the action of Jiuyan, the mouth of the cave expands at the speed visible to the naked eye.

Nine Yan side enlarge hole, side say: "I just probe out, aware hole is not smooth!"

The whole holy mountain is extremely smooth, but the entrance is not like this. This shows that the area of the entrance is different from the rocks of the holy mountain.

After a short time, Jiuyan enlarged the hole to the size that can accommodate a person, and at the same time, he made a "Yi" sound.

"What's the matter?" Chen Hui asked immediately.

"This hole should have been sealed. It may have been exposed by the sun and wind for many years." Jiuyan said: "moreover, the stone sealed at the entrance of the cave is different from that of the holy mountain. You see, I easily enlarged the entrance just now, but now I can feel the smooth stone, which is the same as that of the holy mountain."

Jiuyan is a seven step cultivation. Ordinary rocks are under her hands, just like tofu. That's why Jiuyan can expand the hole so quickly.

Nine Yan said this at the same time, let go of his body, stick to the wall of the passage, let Chen Hui to touch the rock of the entrance.

Chen Hui touched it. Sure enough, Jiuyan could feel the smooth rock at this time. This is the unique characteristic of Shengshan rock.

Chen Hui ran around the cave and found that there were some unsmooth rocks on the left side. At the moment, he moved his aura and expanded the cave like Jiuyan.

It's easy for these unsmooth rocks to fall down.

Moreover, the smooth rocks were soon exposed.

Chen Hui once again used aura to attack the smooth rock of holy mountain. However, this smoothness is not only unable to fall, but also has no place to bear force. Chen Hui's aura is useless.

Nine Yan see this scene, sneer for a while, said: "I seven levels of cultivation, can't damage the sacred mountain rocks, what do you think?"

"Just trying." Chen Hui smiles and says, "shall we go out?"

"Be careful!" Jiuyan nodded, told Chen Hui and Su Yin, then walked out of the cave first.

The location of the cave is a little bit high, about 50-60 cm above the ground. After Jiuyan came out of the cave, he looked around again and said, "come out, no one!"

By the time Jiuyan said this, Chen Hui and Su Yin had already come out of the cave. The ground 50-60 cm high from the cave was a flat area. It was just smooth and could still fall.

If it is as steep as at the foot of the mountain, it will not be able to fall completely.

This flat area is very large, about a few hundred square meters.

Chen Hui looked around and found that they were on the top of the holy mountain.

Standing on the top of the holy mountain, you can't see below at all, because it's really towering, and the whole mountain top is hidden in the clouds from below.

Chen Hui and his family were at the top of the mountain, a distance higher than the clouds. Looking down, they could only see the white clouds, but not the foot of the mountain.

"Over there!" Su Yin refers to the middle of the flat area.

Looking at the place where Su Yin pointed out, Chen Hui saw that there were two huge stone gates in the middle of the mountain, at least 10 meters high and about 5 meters wide.

Chen Hui and the three of them went to the stone gate and stood still, looking up at the huge stone gate.

At the top of the mountain, there is such a stone gate. It's hard to imagine what it looks like behind the stone gate.

At this time, Jiuyan went to the stone gate and stood still. He reached for the stone gate and said, "it's as smooth as the stone of holy mountain. It's impossible to push it open!"

Such a large stone gate, even if it is not such a mountain stone, is also very difficult to push open.

What's more, the stone material of Shimen is the same as that of Shengshan. It's extremely smooth and there's no focus at all. How can it be pushed open?

The two stone doors have no any pattern, just like two smooth huge stone slabs.

However, the gap between the two stone doors is very small. I'm afraid I can't even insert a needle. We can see how high the precision is.

Chen Hui looked around the stone gate and found that there were no other buildings except this flat area and the two stone gates.

Of course, snow is not included, because the top of the mountain is very high, covered with a layer of snow.

The snow must not melt for a long time.

"What is this?" Su Yin also went to the side of the stone gate at this time, but saw the different place on the stone gate.

Hearing Su Yin's words, Chen Hui and Jiu Yan all went over and stood in the middle of the two stone gates.

Jiuyan went to the middle of one of the stone gates before, and didn't see the area that Su Yin saw. At this time, when he went to the middle of the two stone gates, he found that the two stone gates were divided into left and right, and at the same time, they had a very shallow palmprint at the height within reach.

On the stone gate on the left is the palmprint of the left hand, and on the stone gate on the right is the palmprint of the right hand.

"Who has such great ability to leave a handprint on such a stone gate?" Nine Yan suspicious words, spread out his palm to see, and then put his left hand into the left side of the stone gate of the palmprint.

"Isn't it the mechanism that opens the stone gate or something?" Chen Hui said at this time.

"It makes sense!" Nine Yan said words, put his right hand into the right side of the stone gate of the palm print.

"No response!" Jiuyan looked up at the two huge stone doors and said.

The two stone gates didn't move. It's not that they didn't respond. It's something.

"I'll try." Su Yin said at this time.

Hear Su Yin words, nine Yan immediately step back, the position that oneself stand gave Su Yin!
