"It's so beautiful, it's like a firefly!" Jiang Jie said with emotion.

"This isn't a firefly, that's what we usually call ghost fire fluorescence." Professor Jin smiled and said to Jiang Jie, "Ancient superstition said that this phosphorus fire is a ghost. ”

Jiang Jie also smiled: "If that's the case, there are hundreds of phosphorus fires here, which means that there are hundreds of ghosts." Aren't we in the devil's lair? ”

I leaned against the mountain wall and stared at the ghost fires for a long time, and I didn't think they looked like phosphorus fires. I tried to touch this ghost fire, try its temperature, if it was really phosphorus fire, it must be very hot. But when I tried to reach for a little fluorescence that was approaching me along the mountain wall, it seemed to sense something, avoided me, and drifted in the opposite direction. I couldn't help but be stunned, and subconsciously took a step forward, trying to catch up with the ghost fire, but I almost stumbled.

I looked down and saw that my shoelaces had come loose and tripped over me. I lowered my head and fastened my shoelaces, and as soon as I straightened up, the back of my head hit a raised stone on the mountain wall.

"Oops~" I immediately squatted on the ground and screamed in pain.

"What's wrong, poor ghost?" At this time, he had already walked to the jar in front of me and shouted to me.

"No, what, what~" I gritted my teeth and said, the pain was like cutting meat, but I didn't forget to tell the altar: "I hit my head!" ”

"Oh~" When the altar heard that it was okay, he stopped caring about me.

I covered the back of my injured head, slowly stood up, this time I was dizzy, I couldn't see clearly for a long time, I rubbed the big bag in the back of my head and said to myself: "Will it be a concussion...... who knows, as soon as I raised my eyes, I saw that the floating ghost fire in front of me was gone, and turned into a floating, transparent figure, some floating on the top of the cave, some standing on the water, some standing on the ground, some drilling in and out of the stone wall...... These figures were dressed differently, their expressions were dull, and their eyes were all looking at the team that had already walked by. It was as if they sensed that I was looking at them, and they turned their heads back to look at me......

Could these be the ghosts of the dead here? Seeing those resentful spirits slowly approaching me, their expressions gradually became hideous, their mouths were so open that their jaws were about to drop, and they reached out and pounced on me......

At this time, my head was still very dizzy, and I almost fell to the ground when I tried to run. Seeing the resentful spirit approaching, I had no way to escape, so I could only close my eyes and wait for death, while muttering: "Ghost, really ghost......"

But I waited for a long time with my eyes closed, but I didn't see any movement. When I tried to open my eyes again, the transparent spirits were gone. Floating in front of my eyes are still those "ghost fire phosphorescence" of unknown origin......

Just when I was in doubt, wondering if what I had just seen really existed, or if it was because of the illusion that my head had been hit and I was dazzled for a while, the altar called out to me in front of me again: "Let's go, what are you stunned there for?" You'll be left behind, but no one will turn back to pick you up! It turned out that he saw that I hadn't come up for a long time, and he was a little worried, so he asked again.

"Hehe~ Where did so many ghosts come from?" So, I shook my head, threw out all the thoughts I had just made, put aside my doubts for a while, and strode along.

After walking for about half an hour, we came to the end of the cave...... At the end of the cave is also a large cave hall, and there is also a pooled pool in the cave, which is connected to the outer waterhole by a river.

As soon as they saw that there was no way out in front of them, everyone was a little surprised: "Isn't the clue in the palace of King Naluo pointing here?" How could there be nothing? "Didn't you say there were any palaces here? Where? ”

"Let's all look for it, see if there's any mechanism?" Mo Ji had no choice but to tell everyone to pay attention to it.

Although this cave hall is not small, it is very quick for so many of us to find it, but we have found nothing.

"Get into the water!" Professor Jin suddenly said, "Since the map points here, it means that there must be something here...... If you can't find it on the ground, you go underwater...... We have diving equipment anyway, don't we? ”

"Yes, yes, there are still underwater, and there are underwater ......" Mo Ji also vigorously agreed, he didn't want to come out in vain this time, he was still thinking about countless treasures and the legendary elixir of immortality.

This time, Professor Jin plans to go into the water to find it himself, and I and Master Liang plan to go with him, and there are two bodyguards with us. The five of us put on our diving equipment and slowly descended into the water. Judging from the fact that the giant toad is able to live in the water, as long as it is not disturbed very violently, the water body will not emit a large amount of carbon dioxide. Once we have grasped this pattern, every action is very slow.

We dived into the water and kept an eye out for the surroundings of the waterhole as we slowly dived. The whole pool did not go straight up and down, but like a stick that had been stuck diagonally down.

After diving to a depth of about ten meters, the buoyancy in the water is already very large. Suddenly, the light on Professor Jin's side flashed three times in a row, and we immediately swam towards him. In the water, we have no way to communicate, we can only use lights.

Professor Jin pointed to the rock wall over there, and we could see clearly, the rock wall was covered with mox, but there was a large piece of bryophyte that was much thinner, square, easy to distinguish, and had a strange bulge on it.

We removed the moss from the block, revealing a door with a trap. Now I understand why the moss on the door is thinner, it must have been someone who removed the moss from the door and opened the door before. As for who it is, just think about it, it must be Cao Xuan's person. Although Cao Xuan is a warlord, I still feel very admired, because he was able to find this place, and it seems that there must be talents in this field in the team he leads.

I moved the mechanism and opened the door in the water little by little. When I first opened a gap, I felt a burst of suction, but it disappeared in an instant. When I opened the door, I found that it was a stone room, but it was also filled with water. However, considering the situation just now, this stone room should be without water before it opens. The water in the stone chamber in front of me must have just been filled in.

The stone chamber is not very large, and it can only accommodate seven or eight people. The inside of the door has the same opening mechanism as the outside. The door should be able to open both inside and out.

Professor Jin took me and Mr. Liang into the stone chamber first.
