After Ning Xue came down, she saw her uncle and nephew hooking their waists and meticulously searching in the water with flashlights.

"Did you find it?" she asked. ”

Wang Yu stood up and shook his head: "Zihang said that it should have fallen into the water here, but we haven't found it yet." ”

Liu Zihang said: "Uncle Cousin, did you think it was washed away by the water?" ”

Wang Yu said: "Probably not, the water flow here is very gentle, not enough to wash away a jade ring, and looking at the rocks on both banks, the traces of the water level are very clear, indicating that this dark river has not risen in this period of time." ”

Ning Xue rolled up her sleeves, picked up the flashlight and went into the water: "I'll help you find it together." ”

Fat guy was the last to come down.

When he reached the bottom of the cave, Wang Yu and the three of them had already turned this body of water upside down, and they still didn't get anything.

Liu Zihang said angrily: "It's really strange, the ring fell from the hole and should have fallen into this water, but why can't I find it?" ”

The fat brother said: "Don't worry, you will always be able to find it if you look slowly." ”

"Look, what's that!"

Liu Zihang pointed to the water upstream in surprise.

On the dark water surface, a cloud of red light floated out, constantly changing shapes in the water, looking very weird.

Wang Yu shouted: "Come ashore!" ”

The four of them ran up to the shore together, craned their necks on the river beach to look at the red light that was getting closer and closer.

It turned out to be a false alarm.

The red glow is just a glowing fish in the water.

The shape of these fish is similar to that of grass carp, each of which is about two or three catties, and the scales glow red in the dark.

Ning Xue said in surprise: "This kind of fish is so amazing, it can be self-luminous, and the fish that can generally self-luminous are deep-sea lantern fish that live thousands of meters under the sea, but I didn't expect freshwater fish to be able to do it." ”

Fat brother said: "This kind of fish is called red cold fish, generally lives in the underground dark river, the number is very scarce, once it leaves the underground dark river environment, it will die quickly, it will die within three minutes after its death, the fish scales will fade into no different from the general grass carp." Therefore, only those of us who often explore the underground can have the privilege of seeing them in their most beautiful form. ”

Speaking of this, the fat brother seemed to remember something, so he said excitedly: "I almost forgot the most important point, the eyesight of the red cold fish is very poor, they prey on the red light reflected on the plankton with their own red light. In other words, they often accidentally ingest objects that reflect light. ”

Ning Xue was suddenly shocked and said, "Speaking of which, isn't it possible that the Linglong Jade Ring was mistakenly eaten by these red cold fish and taken elsewhere?" ”

Wang Yu also thought of this, and he immediately looked at the group of red cold fish in the water, and found that they had swam down the gentle river into the river hole below.

"Ahh

Liu Zihang suddenly exclaimed at this time.

"What's wrong with you?" Wang Yu turned around and asked.

Ning Xue and the fat brother also looked at Liu Zihang in confusion.

Liu Zihang squatted on the ground, covered his bare feet with his hands, and said with a somewhat painful face: "It seems that something scratched my foot just now." ”

Ning Xue was taken aback: "Zihang, why did your feet bleed so much?" ”

Wang Yu hurriedly shone a flashlight and found that Liu Zihang's bare foot had a wound about five centimeters long, which was bleeding out.

"I've got gauze here!" The fat brother immediately opened his backpack, took out gauze, and the three of them surrounded Liu Zihang and helped him bandage his bare feet.

"Thank you." Liu Zihang stood up and said gratefully.

Wang Yu groaned: "How did you get hurt? ”

"I just suddenly felt a chill under my feet, and when I looked down, it was like that." Liu Zihang said helplessly.

The fat brother said: "Looking at the wound, it doesn't look like it was bitten by an animal, but scratched by a sharp object, but there are smooth pebbles on this shore, and there are no sharp objects." ”

"Look! The bag is gone! Ning Xue suddenly exclaimed.

The bags that were still in place before, just when they were busy bandaging Zihang, came back to their senses and turned out to be all gone.

"How so?" The fat brother rushed forward and took a flashlight to shine around, "Didn't everyone's bags just now be in this place?" ”

Liu Zihang gasped and said, "Uncle Cousin, this place should be ...... There shouldn't be ghosts! ”

As soon as he finished saying this, the candle on the ground went out with a clatter.

Wang Yu was shocked: "Fat brother, come back quickly!" ”

The fat brother reacted a step slowly, and a bulging sand dune on the ground quickly moved towards him, knocking him straight to the ground.

Liu Zihang immediately reached out and pulled the fat brother back.

At this time, more than a dozen sand dunes suddenly moved in all directions, showing a trend of surrounding the four people.

Ning Xue was surprised: "What are these things?" ”

Wang Yu pulled out the victory demon, and the end of the sword pierced into a suppression talisman, and then slammed it into the earth.

In an instant, more than a dozen sand dunes began to collapse, revealing skeletons within.

Ordinary skeletons are white, but these skeletons are as black as carbon.

Half of them were on the ground, half of them were buried in the ground, and they were all scrambling to climb up.

For today's Wang Yu, these little minions are not vulnerable at all.

He threw a few clusters of white spirit fire with his backhand, instantly igniting the skeletons, causing them to lie on the ground and struggle in agony.

After the yin qi on the skeleton's body was burned by the white spirit fire, they all turned into ordinary skeletons and fell on the river beach in a mess.

The fat brother said with palpitations: "They...... They're dead, aren't they? ”

Wang Yu nodded and stepped forward to observe.

Ning Xue asked curiously, "How can there be so many skeletons in this bottomless pit?" ”

Wang Yu said: "I heard from the old people in the village that probably in the early days of the founding of the People's Republic of China, there was a scientific expedition team to explore the bottomless pit, but there was no return, and even the people who came back with rescue were all wiped out. So since then, our village has stayed away from this cave, and no one dares to approach it again. So these skeletons are probably the dead at that time. ”

Ning Xue glanced around, frowned, and said, "This bottomless pit is a little deeper, and the oxygen at the bottom of the pit is also very sufficient, how could they all be killed?" ”

Wang Yu can't figure out this question, it stands to reason that as long as he can come down, he can return the same way, but why can't these people go back?

On their remains, Wang Yu seems to have found the cause of death.

"These people must have been burned to death, that's why their bones are this charred black," he said. ”

Liu Zihang said: "Uncle Cousin, you are usually burned to death by fire, and your bones are not black, right?" After all, there is a layer of flesh on the outside, and the flames can't directly contact the bones. ”

"You're quite right." Wang Yu stood up and said: "The only possibility is that the temperature of those flames is very high, so high that they can directly burn the muscles and fat of human tissues, and directly contact the bones. ”

Ning Xue said: "With such a high temperature, I'm afraid that even a professional funeral home crematorium can't reach it." How could there be flames in a cave with such a high temperature. ”

"Buzz buzz!"

Suddenly, there was a swarm-like sound overhead.

Then I saw that the stalactites gradually turned blue, just like the ice cubes of the deep sea, which was very bewitching and beautiful.

But if you look closely, you will find that the glowing blue layer is actually a dense layer of small insects.

The fat brother was shocked and said, "Phosphorus bee! It's a phosphorus bee! ”

Wang Yu hurriedly asked, "What kind of bee is that?" ”

The fat brother said in a panic: "The phosphorus bee is not a bee, but a small insect that looks like a bee." We all know that white phosphorus burns when it hits air. And once the phosphorus bee touches a warm-blooded animal, it will also burn, hence the name. This creature usually lives under the ice of the Himalayas and can sleep for hundreds of years, but I didn't expect it to exist at the bottom of this cave. ”

Wang Yu now knew how these people died, and the reason why they couldn't leave was because they were attacked by these phosphorus bees.

He himself was not afraid of the flames of the phosphorus bee, but Ning Xue and the three of them couldn't.

"Get out into the water!"

Wang Yu was about to let everyone go into the water to dodge, but the fat brother said: "No, the flame on the phosphorus bee is very special, and it can burn without oxygen." ”

Listening to the fat brother say this, it is definitely not possible to go into the water, otherwise not only will it fail to block the attack of the phosphorus bees, but it will also be dragged down by the resistance of the water flow.
