Without the obstruction of the monster, we successfully entered and exited the river several times and successfully marked every part of the cave below.
In the end, we determined that several of these dozen caves were dead caves, as if they had been carved into extremely hard ore, and we could no longer move forward, so we stopped carving.
Other cave entrances are filled with stone gates, with a total of eight stone gates.
Among these stone doors, seven of them are round, and only the one I discovered at the beginning is square.
The square stone door is extremely large, much larger than the surrounding fan-shaped stone doors.
besides.
We also took pictures of the outside of these stone doors. The carvings on the outside of the remaining circular stone doors are roughly the same.
They are all coiled dragons rising from the bottom, with layers of clouds carved around them.
It means the dragon ascends to heaven.
And that rectangular stone door has a giant dragon coiled around the edge.
It's just that there are vaguely seven stone sculptures missing from the dragon's body, and seven holes clearly appear in various parts of the dragon's body.
It's as if something needs to be inserted to open this stone door.
After I expressed my speculation, Cui Hao also agreed with my idea.
"When I was swimming below, I also felt that the square stone door seemed to be placing something on the dragon's body. Logically speaking, it should be the key to opening the stone door."
Cui Hao looked at the other seven round stone doors.
"Do you have a feeling that the seven keys on this square stone door are probably behind these seven round stone doors."
I didn't expect this originally.
After Cui Hao reminded me, I suddenly reacted.
It's very possible.
It is very likely that the keys to unlocking these mechanisms are all inside the remaining doors.
We need to check them one by one and take out all these keys.
I immediately winked at Cui Hao.
"Let's go, then let's go check out these cave entrances."
After just a few swims, we have roughly observed the situation below.
No second monster rushed out.
Presumably, even if we go down, there won't be much danger.
Cui Hao nodded to me and immediately expressed his intention to take the first shot.
To be cautious, we decided that one of us would stay on the shore and the other would swim down instead of going down together.
After all, the risk is too high if we go together. If something happens, both of us will end up here.
After Cui Hao entered the water, I waited on the shore.
After four or five minutes, he swam up from below with a gray face and helplessly spread his hands towards me.
"No, I didn't find anything. The stone door was tightly closed, there was no entrance at all, and there was no mechanism to open the entrance. I don't know how to get in at all."
I took a breath.
Since such a cave has been set up here, there is absolutely no reason why it cannot be entered.
The switch must be still hidden in a hidden corner, and the two of us didn't find it.
I nodded and tied the rope and jumped directly.
Cui Hao grabbed the rope around my waist and waited for me silently on the shore.
Once again, we came to the round stone arch.
I reached out and started groping on the wall.
Coiling the dragon and flying into the sky, the state is extremely comfortable and leisurely.
I looked at the flying dragon and the dense scales on his body.
I suddenly had a guess.
"If the coiled dragons above are not meant to let us in, or it can be said that this is not a stone gate, but a fake stone gate, then maybe there is no dark room here at all. I am going in the wrong direction."
I carefully lay down on the edge of the door crack, stretched out the dagger and pierced it inside.
The moment I pierced it with the dagger, the dagger penetrated less than half an inch and stopped.
"There's a problem, there's no crack in the door."
I carefully followed the crack in the door and discovered that the crack in the door was narrow and shallow, and it didn't look like a normal stone door at all.
Think about it.
I immediately swam out from below and quickly swam to the side of the square stone door.
I used the dagger on the edge of the square stone door and stabbed inwards hard.
This time the dagger successfully penetrated more than four or five inches.
My heart shook, and I almost had an answer.
Those so-called arched stone doors are simply fake stone doors. It is impossible to enter at all, and there is no secret passage behind them.
They may be placed on the wall just for decoration.
On the other side, this square stone door is real.
There is a passage at the back that you can enter.
So for those round arched stone doors, I just need to carefully observe the edges to see if there are any mechanical designs inside.
Maybe the key is hidden on this carved wall.
He immediately turned around and swam quickly to the side of the arched stone door, ready to take action.
I soon found out.
There is indeed a problem next to this arched stone door.
There is a scale on this Coil Dragon's body that can be moved.
I tried shaking it from side to side, trying to take out the scale.
After some more troubles, I actually took out the stone fragments.
And what is carved on the top of the stone is a dragon scale.
This piece of dragon scale clearly corresponds to the holes on the square stone door, and there is a high probability that it can be inserted directly into it.
"It turns out to be this."
There was not much oxygen left, so I quickly swam out of the water with this dragon scale.
When I came to the shore, I gasped for air and told Cui Hao the news I found below.
Cui Hao's eyes lit up when he looked at the stone in my hand.
"In other words, the other stone doors are just decorations, and all the keys we are looking for are within the scales of the dragon carved on these stone doors."
The fat man volunteered and was about to jump down with a backpack on his back.
"I'll go, I'll take out the other six, and then we're going to explore the situation inside the square stone door."
I nodded and didn't stop him.
After all, judging from the current situation, there shouldn't be too much danger down there.
Even if the fat man goes to get a few more stones, there is a high probability that nothing unexpected will happen.
The fat man entered the water and swam out after nearly five minutes.
At this time, in his hand, he was holding several stones, all of which were dragon scales on the carved surfaces of the stones.
Cui Hao handed all these things into my hands and then spit out a mouthful of water.
"Bah, we finally took out all these things, what should we do next? Should we continue to go into the water one by one on the shore?"
I shook my head.
I had thought about this problem just now when I was on the shore.
Because I didn’t know the situation underwater before, for the sake of safety, I decided to do one on the shore and one under the water.
But now the situation has changed.
We have all found these dragon scales and are about to open the stone door.
The space behind the stone door is unknown, so if there is any danger inside, the two of us can have some company.
Thinking of this, I asked Cui Hao directly if he would like to go down with me.
He nodded extremely excitedly.
"Of course. In fact, I was worried that if the stone door was opened and there was something inside, it would be really difficult to deal with one person. You just said that the two of us can go together, so let's go down together to see the situation. "
I grabbed another section of the end of the rope, found another section of rope and tied it tightly, and tied this end around my waist.
The two of us were like Siamese twins, tied directly together by a rope.
In this way, if something happens to one person, the other person can come over in time to provide support.
We took the seven dragon scale stone sculptures and quickly swam to the square stone door cave.
Cui Hao and I picked up the dragon scales carved from stone and began to piece them together on the wall.
Since these dragon scales vary in size and shape, they will not fit in every hole.
It took the two of us a long time to put together all six pieces.
Only the last piece remains.
I looked at Cui Hao. He nodded at me and stood aside silently.
I pushed his shoulder and pushed Cui Hao into the corner.
If there is a mechanism inside, we can escape in time.
I stood at the edge and pressed the last stone in hard.
The next second.
The stone door made a rumbling sound.
Immediately afterwards, the square stone door in front of us suddenly lifted upwards.
A huge hole two square meters square was quickly revealed.
There was a suction force coming from the hole. There was no water in it, but suddenly the stone door opened, and all the surrounding water pushed Cui Hao and me crazily, and the two of us were washed into the hole.
The two of us didn't even have time to react before he slid right in.
"Cui Hao, be careful."
While the water is not strong, there seems to be oxygen around.
I immediately shouted to Cui Hao.
I don’t know if he heard it, but Cui Hao didn’t respond for a long time.
I firmly grasped the raised stones on the wall next to me and managed to stabilize my body.
The fierce river water kept washing me, and I could hardly stand still.
I tried to hold on to the wall and climb out, but the fiercely rushing river didn't give me this chance at all. The river washed me down again and again.
If I hadn't held it tightly, it would have been washed down by the river long ago.
Cui Hao is relatively large, so he may not have grasped the wall just like me. At this time, he should have rushed down along the raging river.
The water flows incessantly.
The space below is also extremely large. I had no idea how big the space was and could hold so much water.
Just when I thought I was going to die here.
I suddenly found that the stone door in front of me began to press downward.
And the originally turbulent river was suddenly blocked a lot.
The stone gate suddenly penetrated the river water and smashed down hard.
The fierce spray of water stopped completely in an instant, and no more water could flow in through the crack in the door.
I touched around.
Now the water spray under my feet has grown up to half the length of an arm, almost reaching my knees.
