Although there were some traces of corrosion on the raft found by Cai Junhua, it was still quite solid overall. Su Peng and the other two tried it and said that the raft should be able to carry three or two more people.

The wood pulp found was already a little smooth to buy. Some fungi that grew in premature humid environments had grown on it. However, after a little treatment, it was found that the wood pulp did not rot and could still be used.

After confirming that these things were still available, the three of them didn't say much, so they pulled the raft into the underground river and jumped up.

Liang Wei was a lady, so naturally there was no reason to let the lady work hard to row the raft. Su Peng handed the torch in his hand to Liang Wei, and then stood on both sides of the raft and maintained balance, paddling the raft with the wooden pulp in his hand.

In fact, the two of them don’t need to put in much effort, because this underground river has its own direction, and they can reach their destination by just going downstream. The existence of wood pulp is to avoid reefs and other things that may be found in the river.

The three of them rode on a raft and drove towards the depths of the underground water vein.

The water flow of this underground river is not fast, but the flow rate is not slow. Su Peng and others are moving forward on the water at a speed that is almost equal to a medium speed.

"Brother Qi, we drifted into this cave for about three hours, and we almost arrived at the place."

Cai Junhua said to Su Peng while controlling the wooden pulp.

"Three hours? Wouldn't that meant about thirty or forty kilometers?"

Su Peng estimated his current speed and said to Cai Junhua.

"It's almost this distance. It's so far from the entrance to the waterfall we came in... And when you get there, you will know that the environment of that secret realm is completely different from the place we entered. The temperature is much higher than that here. The environment is not like the original forest of the Greater Khingan Mountains when we came, but it's a bit like the rainforest of South America. The plants are also different from outside... From my estimate, it should be a natural basin, but the basin is a bit out of tune, and the altitude is very low. It should be less than two or three thousand meters below sea level. However, because of the unique landform and I guess it may be due to geothermal heat, a special secret realm has formed."

Cai Junhua said to Su Peng while paddling the raft.

"Oh? Just to those special hidden terrain that is said in reality that may allow dinosaurs and other creatures to survive until today?"

Su Peng remembered some unsolved mysteries and other programs he had watched in reality and said casually.

"It's almost the same. You haven't been there, so you can't imagine how strange the ecological environment of the plant circles there is. It may be because of the special terrain of the huge basin and many strange plants. The oxygen content there should be much richer than outside, so some creatures that cannot survive outside can also be seen in places where there are some creatures that are several times larger than ordinary sizes."

After hearing this, Su Peng was immediately curious about the secret realm described by Cai Junhua. If he could take a look there, even if there was no particularly valuable treasure, it would be slightly worth the ticket price.

While the two were talking, Liang Wei, who was holding a torch on the raft, suddenly spoke: "Shh! Don't talk, do you two hear any sounds?"

After hearing Liang Wei's words, Su Peng and Cai Junhua immediately became alert because of the huge monster toad just now. Su Peng used his skills in his ears, and sure enough, he heard a sound that seemed familiar.

If the sound was not enhanced with internal force, it would not be easy to be heard. However, after strengthening, Su Peng could hear it clearly. This should be a relatively large flying creature that kept flapping its wings.

However, the sound and trajectory of the creature's flying seem to be a bit special, and the sound is almost inaudible. However, when you use your power on your ears, you can hear that it should be a relatively large flying animal.

"What?"

When they heard this voice, Su Peng and Cai Junhua were also a little uneasy, because they could tell from the sound wave that the flying creature was at least half a person in size, and there were a lot of them. If this thing was group and aggressive, it would be very difficult to deal with.

"Look! What is there?" Liang Wei, who was looking for the source of the voice, suddenly shouted.

Su Peng and Cai Junhua looked in the direction Liang Wei pointed, and saw four or five corpses hanging on the stalactites on the cave stone walls on both sides of the underground river.

Originally, the light of Liang Wei's torch could not shine so far, but there were some shining moss and other things growing on the stone walls of the cave, which allowed Su Peng and the other two to see clearly what was hanging on the stalactites on the cave.

At this time, Liang Wei was awakened, and Su Peng's eyes gathered internal force and looked at the corpses.

After just a look, Su Peng was disgusted. He saw that the skins of the corpses seemed to have just died and had not completely decayed, but their bodies seemed to be fermented by water, which was almost twice as big as those reminders of ordinary people.

But this is not the place where the scalp is numb the most. What makes people feel really chill is that four or five corpses can be vaguely seen a large green flesh worm constantly squirming in the corpse. Each of the green flesh worms has a diameter of more than 20 centimeters, and there is only one of the corpses, but it is twisting very hard at this time.

Looking at this, it was as if the fermented corpse was the food of these meat worms.

When Su Peng saw this scene, his back felt numb. At the same time, he also realized what were the flying large creatures he had heard before.

"Beware! There may be giant moths here!"

Su Peng tried his best to lower his voice and reminded Liang Wei and Cai Junhua.

Su Peng's inference was very simple. He had a minimum biological attempt. When he saw the flesh worm on the fermented corpse, he thought that this flesh worm would definitely make a cocoon after its maturity. However, this was obviously not a larva of a butterfly, but it probably turned into a moth.

It is the kind of moths that always gather when the street lights are on in summer nights.

Sure enough, as soon as Su Peng finished speaking, he heard the huge creatures flying in irregular trajectories flying from somewhere in the cave towards Su Peng and the other three.

With the light of the torch, Su Peng and others also saw clearly what was flying in.

There were about twenty, with a body length of more than one meter or more, a yellow-brown color, and a huge moth on its wings that looked like a skeleton!

The sound of these moths dancing is not very loud. Only when they get close can they feel the sound of flapping their wings. The moths have their heads that look like shrinking skulls, and there is a mouthpart like a long tube under their mouth. The feet that look like they can wrap an adult are enough to make people frightened.

"What monster?"

When Liang Wei saw these moths, he was already a little stunned. No woman likes moths, let alone such a huge and terrifying moth?

And Cai Junhua also changed his brilliance.

He is also a person with vision. Some huge and terrifying moths appeared here. The corpses on the stalactites I saw before have shown that these moths are probably not vegetarian animals.

At this time, Su Peng and the other two were on the raft. The space to be used was too small to move at all. If all the huge murderous moths flew over, the three of them might fall into the water.

At this time, the entire cave was occupied by groundwater veins. Once it fell into the water, with the temperature of the water, even if the three of them had strong internal strength in martial arts, they might not dare to say that they could swim to their destination.

Not to mention, since such a fierce and terrifying moth appears here, will there be other more dangerous things under the water?

The terrifying huge murderous moths in the sky were flying in the air and were about to fall.

"Liang Wei, throw away the torch quickly!"

Su Peng suddenly shouted loudly at this moment.

When Liang Wei heard this, her body trembled. She instinctively didn't want to throw away the light source under such a terrifying situation.

But she immediately realized that no matter how huge these moths were, they were still moths, and they were light-taping. At this time, the torch in her hand was the brightest light source in the cave, and those moths would definitely come to her.

But throwing away the torches does not mean that the giant terrifying moths will not attack them. After all, the larvae that look at those moths are all human flesh.

If you throw away the torch, Su Peng and others' vision will be greatly reduced. I really don't know whether it is better to throw it away or keep it.

"Listen to Brother Qi!"

Cai Junhua also shouted at this time. Although he was worried that there would be no light source for a while, the terrifying moths would come to attack him and others, it was better than his wife being attacked by the moths.

After hearing this, Liang Wei hesitated a little, and finally waved his hand and threw the torch far into the underground river behind him.

Just as the torch flew out, the huge terrifying moths flew towards the place where the torch was thrown away.

Cai Junhua's heart was already in his throat at this time. All these terrifying moths flew over, and the three of them could not stop them just by themselves.

"Don't talk!"

At this time, Su Peng whispered to Cai Junhua and Liang Wei, and at the same time, he quickly penetrated into his arms and took out a talisman paper.

Almost instantly, Su Peng used his magic power to activate the talisman paper in his hand.

"call!"

Cai Junhua and Liang Wei immediately felt that the entire raft was shrouded in a mysterious force.

Even what they could see was that Su Peng and the other three were shrouded in the shadow of a huge bluestone.

But the moths seemed to have suddenly lost their target and could not find Su Peng and the other two.

Su Peng, who was on the raft, felt relieved when he saw this scene.
