Under the impetus of the Ma brothers, the bronze gate slowly opened, and there was a dark passage inside, Lu Jie also ran out curiously, looked at the wall behind the hall, and made sure that there was no passage behind the bronze gate, which felt very magical.

In view of the experience of the "Water Prison", this time Zhou Tianzuo equipped everyone with a fully wrapped gas mask, so that we were not ventilated from top to bottom, or connected with ropes, and strictly led a team of people to lead the way, with us standing in the middle and chasing the wind behind the team.

I connected with Nangong Xinyue, Xiong Dali and Miaoqing to form our four-person team, I know Miaoqing's physique, I don't know if it's his cultivation in the Valley Realm or other reasons, psychedelic organs don't work for him, and my physique can also resist the invasion of some toxins, so the four of us Miaoqing took the lead, I cushioned, Xiong Dali and Nangong Xinyue were protected by the two of us in the middle.

We entered the bronze gate in turn, it was still a dark passage, we walked for more than half an hour, and we were still in this dark passageway, I was sure that this time it was not a hallucination, and it did not spin in place, but all the way forward, because every other way a scratch was drawn on the wall as a mark, and now we have not seen the scratch I carved.

I whispered to Ling Youyang behind me: Dao Chief, check it, did we fall into the ghost and hit the wall?

Ling Youyang took out a talisman while moving forward with the team, the talisman was stimulated by spiritual power, and it burned instantly, Ling Youyang shouted: Hurry like a law, open.

The talisman erupted, instantly illuminating an area around us, Ling Youyang shook his head and said, "I have not been hallucinated by ghosts and other things, and my barrier-breaking talisman has not been blocked by yin qi.

I looked around by the light of the spotlight, and it looked like a cave, and unlike the pure black of the dark passage that had just entered the bronze door, there was a reflection of stone on the cave wall.

After another ten minutes of advancement, I suddenly felt a liquid dripping on me, which made me shiver, and I looked up nervously because of the last experience of hallucinating by the phantom spiral slime.

It turned out to be the water droplets dripping from the stone stalactites on the head, I was relieved, the cave here is slightly different from the previous one, the cave wall is relatively damp, and there are stone stalactites, the light shines on the colorful color, particularly beautiful.

Zhou Tianzuo shouted: The presence of stalactites here means that there should be a water source nearby, and perhaps an underground river. All we have to do is find the underground river, we can go down the river and find the exit.

Through a narrow passage, we came to a huge cave hall, where the roof of the cave was full of stalactites, and the colorful and bizarre natural scenery was really strange, and everyone was fascinated by the scenery.

It's so beautiful, our country's karst cave resources are so rich, but they don't have so many here, so big, Nangong Xinyue said excitedly.

Look at that, doesn't it look like a sheep? Over there, over there, it doesn't look like an old man, Nangong Xinyue pulled me to jump and jump, like a little girl walking in the playground.

Since the cave hall is very large, estimated to be several thousand square meters, we untied the attached ropes and spread them out to move freely.

We admired the magic of nature, behind a huge stalactite we found a waterhole, the waterhole is not big and more than ten squares, there are some thumb-sized small fish swimming around, the light shines on, the small fish emit light blue fluorescence, very beautiful.

There are fish here, it will glow, it is so beautiful! Nangong Xinyue said and wanted to reach out and catch a small fish.

I quickly grabbed her, be careful, you treat it as a scene, be careful that it treats you as food, this is the Hell space, the creatures in it are dangerous, don't touch them casually.

Nangong Xinyue playfully stuck out her tongue and withdrew her hand, but looked at the waterhole reluctantly.

Xiong vigorously took out the Luoyang shovel and some food, the Luoyang shovel was specially made by a familiar blacksmith before leaving, and he crushed the food and handed it to Nangong Xinyue Dao; Sister Nangong, these small fish are so beautiful that they are used to feed, you come to feed, I will take the opportunity to catch a few for you and take them back to raise.

Nangong Xinyue happily took the food scraps, pinched some and threw them into the pool, and those glowing fish rushed to grab the food, which made Nangong Xinyue giggle.

Xiong Dali saw that the small fish had gathered, and suddenly inserted the Luoyang shovel into the water, and caught a few while the small fish were competing for food.

Seeing the small fish on the shovel, Xiong vigorously screamed like Nangong Xinyue to invite merit, how about Nangong sister, brother's hand shovel method is okay, look at this...... Xiong Dali, who was beaming proudly, suddenly stopped, because he saw that a few small fish on the shovel fell back into the pool, not jumping out, but spitting out some green liquid, melting the Luoyang shovel into a round hole, and falling directly.

Seeing this, Xiong Dali and Nangong Xinyue were a little afraid, but fortunately they didn't catch them with their hands, these little fish look so cute, but the sour water they spit out can even melt steel, not to mention our flesh and blood.

The bear was so frightened that the Luoyang shovel was thrown away, and everyone gathered when they heard the movement on our side, and I told them what had just happened, reminding them to be careful of any creatures.

We searched the cave, and found nothing except the beautiful stalactites and the strange little fish in the pool, and someone found the entrance to the cave on the east side, and there was a narrow passage in the hole, and we lined up again and walked along the passage.

After walking for about a quarter of an hour, I came to a huge cave hall, which was much drier than the cave hall just now, and there were many fewer stalactites, some bryophytes appeared on the mountain wall, and there were small flying insects similar to fireflies flying in the air, decorating this cave like a dream world.

Because of the fright just now, Nangong Xinyue became wary of these little flying insects, and did not scream and rush over when she saw a beautiful creature like an ignorant girl.

We cautiously move forward, try to stay away from these blue fireflies, when we walked to the center of the cave, the wall suddenly lit up a large number of fluorescent, it turned out that there were a large number of fireflies on the wall, but when they were stationary, they did not emit light, I don't know if we were disturbed, all the fireflies rose into the air, flying towards a cave, the scene was like a stream of water in the air, it was too dreamy.

All of us lay on the ground tightly, for fear of being caught up in the insect tide, and no one knew what danger these fireflies had.

The swarm flew by, and just when we thought it was safe, a swarm of bats rushed into the swarm like a dark cloud and began to prey on the fireflies, and the swarm was like a huge wave that hit the rocks, and rolled back, and we wanted to retreat to the cave in front of us, but the back was already covered with bats and fireflies.

We climbed out, they were all in the air, the ground was safe for the time being, I said to everyone.

We crawled forward slowly on the ground, and suddenly a firefly fell from the sky and landed on the body of a special combat member, and the blue light of the small flying insect exploded instantly, and then a blue flame flower rose from the special combat member's body, and the team member was silent in an instant.

The team members next to him wanted to go over to extinguish the blue flames, but as soon as they came into contact with the blue flames, they fell to the ground, and Zhou Tianzuo quickly stopped the other team members from continuing to approach.

When the blue flame was extinguished, some team members crawled over and turned over the two people who fell to the ground, and found that their eyes were wide open, but they had lost the color of life.

This blue flame not only did not heat up, but seemed to freeze a person's soul, and instantly took a person's life. A small firefly can kill us, looking at the hundreds of millions of fireflies in the air, the horror of emotions permeates our hearts

Let's go, Zhou Tianzuo urged, now you can only climb as fast as you can, so many fireflies can just drop a few of us and wipe out dozens of us.

Fortunately, the bats were directly devouring fireflies in the air, and no more fireflies fell, and the one just now was just an accident.

After my observation, those fireflies have no chance to explode on the bats at all, and they are directly devoured, it seems that if the fireflies do not touch something, they will not self-detonate to produce a terrible blue flame, and the stomach of these bats must be relatively special, and they can digest the blue fireflies.

But there are still some bats surrounded by swarms of fireflies, and the fireflies that explode make the bats lose their lives in an instant.

We carefully avoided the bats that had fallen inside, fearing that the blue flames on their bodies that had not yet been extinguished would burn us, and finally, most of us climbed to the exit safely, except for a few special operators who couldn't dodge and stayed here forever.

Looking back at the melee scene in the cave, we breathed a long sigh of relief, and felt like we were reincarnated.

No, I can't run, the bear panted vigorously, we ran so far, we should stay away from those terrible creatures, why are there some strange creatures in this world, such a small firefly is so terrifying.

We had been running for almost half an hour, and it was safe to do so, and we came to another cave, where I heard the sound of running water while we were resting.

There's flowing water here, go over and see if it's an underground river, I said to Rigor Rigor .

Rigor walked forward with a few team members, and after a while, we were greeted by a short time, come here, there is an underground river, see that the water flow is living water, it is very likely to lead to the outside world, we can take an inflatable raft.

Hearing this good news, our morale was high, after such a long period of vigorous running, the special combat team members were fine, but we people could not hold on, and now we can sit in a kayak without walking, and it is really not easy to hear the sound of nature in our ears.

The special operators began to inflate the kayak, and this time there was no sonic snail chasing, and we could calmly prepare.

Suddenly, I heard the sound of something falling into the water, not loud, like a pebble falling into the water, and I hurried to look at the place where the noise was made, and saw a few small glowing fish of the kind that I had seen in the waterhole gathered there, as if they were fighting for something.

Nangong Xinyue looked at my spotlight and exclaimed in surprise: There are also that kind of small fish here?

Xiong Dali and Zhou Tianzuo were also alarmed, if there is this kind of small fish in the river that can vomit strong acid, will we not be able to use kayaks to cross the river?

After discussion, we decided to experiment with an empty kayak, the special combat team put the kayak into the water, pushed hard, the kayak slowly drifted to the place where the glowing small fish gathered, we nervously observed the water surface, until the kayak drifted into the distance, the small fish did not make any offensive behavior before we put our minds at ease, it seems that as long as they do not take the initiative to attack the small fish, they are still relatively docile.

Then I thought about the question, what were they fighting for? It seemed to have fallen from the roof of the cave, and I looked to the roof of the cave and saw some smaller bats hanging upside down on the roof of the cave, and they were quickly flown to the side by my spotlight.

Could this be the cave of those bats just now, I suddenly figured out that the small fish in the waterhole are these small fish, and the waterhole is connected to this underground river. That waterhole is the nest of these small fish, they feed on the feces of bats, and the bats eat those fireflies that can produce blue flames, and the feces will have substances that produce blue flames, and the small fish eat their feces for a long time, so they produce the same fluorescence as the blue flame fireflies, and can spit out the strong acid of the molten gold erosion valley.

I told everyone what I had speculated, and they all looked up at the top of the cave, and the little bats on the top of the cave were frightened by so many bright spotlights, and they flew wildly, and suddenly I felt a little dizzy in front of me, and their bodies were moving unobeyed, and they were all the same as me.

I was so frightened that I turned off the spotlights, these bats were weird, I lowered my head first, then turned off the spotlights, and everyone turned off the spotlights according to my actions.

The surroundings turned dark again, and the riotous little bat gradually quieted down and flew back to the top of the cave.

At this time, our dizziness gradually disappeared, Zhou Tianzuo said: It seems that these bats can interfere with our spirit, which is somewhat similar to the phantom snail, but it is not hallucination, it makes our body chaotic and does not listen to the command of the brain.

It's not a long time to be here, it's still a small number of small bats, and if the big swarm of bats come back just now, we won't have a chance to escape.

Hearing our analysis, everyone quickly got into the kayak, and the current was flowing outward, but we still felt that it was too slow, and kept paddling hard.

We hadn't been paddling for long when we suddenly felt that our bodies were not listening, first our minds were dizzy, our eyes were blurry, and then our hands and feet began to disobey and began to tremble like Parkinson's patients. I knew it was bad, it must have been the big bats who heard the confusion of the little bats and thought that someone was going to do their children badly, and rushed back to take revenge.

It stands to reason that the ultrasound of bats is not within the wavelength range of our humans and cannot be received by our ears, but the world cannot speculate according to common sense that the ultrasound of these bats is invisible, but it can affect our minds.

I knew that Myo Ching was immune to psychic shocks, and I could only hope for him. When there is still a trace of clarity in the brain, shout, Miaoqing, tie us up, you quickly row the boat out.

Plopping, the sound of falling water proves that someone has begun to lose control of their bodies and get up and walk around.

What I didn't expect was that not only Miaoqing could stay awake this time, but Nangong Xinyue was not controlled by the ultrasound of the bat, helping me and Xiong Dali and a special combat team member on the kayak to tie our hands and feet, so that we would not fall into the water because of uncontrolled bodies.

The two of them began to paddle the kayak, and as our kayak walked forward, I saw that Zhou Tianzuo was not even controlled by the ultrasound, tying up Lu Jie, Ling Youyang and the two special combat team members on his boat. Also rowing outward.

Carefully recall that in the "Water Prison" at that time, among the crowd who were hallucinated by the phantom snail and walked to the underground river, there seemed to be no figure of Zhou Tianzuo, and because it was dark and chaotic at the time, I can't remember it clearly, could it be that he was not hallucinated at that time, but why didn't he rescue everyone? This person must be hiding a secret. I thought to myself, but my brain couldn't resist the ultrasound after all, and I lost consciousness due to a severe headache.
