Seeing that the underground waterway was gradually turbulent, Su Peng and Cai Junhua rowed the raft to the stone wall to the right of the raft.

By the light of the torches, I could see the harbor-like place ahead.

I saw some rocks, suddenly rising out of the channel, dividing the whole channel into two parts, one on the left and one on the right.

And those reefs, with the flow of water, turned out to be more and more, dividing the waterway into two parts.

According to Cai Junhua, the water in the waterway on the left side will flow into the waterfall that is thousands of meters high, while the waterway on the right side will not be lowered, but higher.

Su Peng and Cai Junhua controlled the raft and rowed into the waterway on the right side of the waterway, and after entering the branch of this waterway, Su Peng obviously felt that the speed of the water flow was a little slower.

In this way, he and Cai Junhua were required to paddle the wood pulp harder, and in this way, the raft drifted for more than 20 minutes.

Soon Su Peng and the three of them looked at the shore of this waterway branch.

The cave is lower than the previous one, but much higher than the one on the left, so that the water can flow into the channel from the direction where it came from, but it will become less and less, and when the water in the channel is too much, it will flow back to the main channel.

And Su Peng and the three of them, after rowing the raft vigorously for a while, have already reached a place where there is no water in this branch.

I saw that at the end of this waterway branch, it was an underground lake, and then inside, there was a cave, but the cave was much higher than here, so that the lake could not be poured in.

Cai Junhua and Su Peng rowed the raft to the shore, and there was a road made of rocks from the lakeside that led to the cave above.

"Brother Cai, do we still have to carry the raft up from this cave?"

Su Peng looked at the terrain. asked Cai Junhua.

"Hehe, it's not necessary, after walking from this cave for a while, you can reach the cliff at the secret place, but this distance is not too far, and it is not easy to walk with a raft...... Last time, Liang Wei and I carried the raft up because we didn't know if there would be a waterway in front of the road, but this time we didn't have to, we also carried a lot of ropes, and when the time came, it would be a big deal to cut wood again in the secret realm. It doesn't take much time to build a raft, but it's easier than carrying a raft around. ”

Listening to his words, Su Peng nodded, and the three of them gave up the raft, but when they left, Su Peng and the three of them still dismantled the raft, recovered the waterproof rope to make the raft, and then walked from the rocks to the cave outside.

There was a trail in the midst of the rocks. Let the three of them climb more than ten meters high and enter the cave that leads to the secret realm of the outside world, and after the three of them entered the cave, they walked all the way. I didn't find anything special, and the journey was fairly smooth.

Finally, after more than twenty minutes, the three of them walked out of the cave.

……

"Ah......h

The three of them were walking out of the cave. Su Peng looked up at the starry sky.

I saw that in the sky, the night sky was like a wash, and the sky was full of stars. When the moon is in the sky, the moonlight shines down, illuminating a silvery white below.

Su Peng looked down and saw that the place he was in at this time was in the middle of a cliff, and below was a basin like a rainforest, and he was about a thousand meters away from the basin below, with a vertical height of about more than a thousand meters, and there was a feeling of being on a mountain peak.

About a kilometer or two away, Su Peng saw a huge waterfall, flying down from the cliff, the falling water continued to flow downward, flowing through the stone walls of those cliffs, falling into the deep pool below, and there was a huge sound.

And below, there are constantly night birds frightening the forest, constantly flying.

"What a big place......

After seeing this place, this was Su Peng's first feeling.

There is no end in sight to this basin, and I don't know how vast the road is.

Even if the location where Su Peng and the others appeared at this time was mid-air on the cliff, Su Peng could feel that this place was different from other places.

If nothing else, the oxygen content here is different from other places.

Su Peng felt a burst of coolness in his mind, and his feelings were extremely clear, needless to say, this was because of the effect of the high oxygen concentration here.

"Brother Qi, let's go down, although it is a cliff here, but be careful, you can still find a way to go down."

Cai Junhua said to Su Peng, and Su Peng took his mind and nodded.

The three of them followed a steep path formed naturally in the middle of the cliff and walked down the luke.

Although this trail is steep, Su Peng and the three of them are all outstanding, and it is not a problem at all.

In about twenty minutes, the three of them had reached the bottom.

Su Peng entered the bottom of this secret realm and immediately found that this place was different from other local plants.

Outside, some of the primeval forests resemble the Great Khing'an Mountains in northeastern China, where most of them are tall deciduous trees, and tropical plants are almost nowhere to be seen.

In the basin below, I don't know what the reason is, it may be because of geothermal heat or special terrain, which causes the temperature to be more than seventeen or eight degrees higher than the outside, and the plants here are actually some rainforest plants.

Even, Su Peng saw a few pictures in books, which should be the kind of tall ferns from the dinosaur era, also growing here.

"It's really a living plant fossil......

Su Peng looked at the tall tree-like ferns in this vegetation, and couldn't help but say.

"Brother Qi, this is just a glimpse of this, and when you enter this forest, you will know how amazing it is here."

When Cai Junhua saw Su Peng's appearance, he couldn't help but smile and said to Su Peng.

Before they could reply, the three of them suddenly heard a gurgling sound from the forest, as if some animal had come out.

Su Peng immediately raised the Bladeless Sword on guard, since there can be that kind of murderous moth in the cave, the animals here are estimated to be very fierce.

Cai Junhua and Liang Wei were also on guard, and in the eyes of the three of them, a huge animal walked out of the rainforest.

After the animal came out, the expression on Su Peng's face suddenly turned into surprise.

I saw that the animal that came out turned out to be a huge bird, but the size of this bird was too huge.

This bird, about two meters four or five tall, is very tall, and its wings seem to be degenerate, his overall reminder is a bit like an ostrich, but the head is much larger than an ostrich, especially a beak, a huge one is not like words, a bit like an axe.

The bird's feet are also very large, they are divided into three prongs, but they are not like chicken-like claws, but a bit like a blade, a complete gray foot on the soles of the feet, there are three blades that stretch like blades, which look very sharp, as long as you step on a person's body, with the weight of this giant bird, it is enough to pierce and trample through a person's body.

At this time, this huge chocobo was looking at Su Peng and the other three with a slightly puzzled look.

The giant bird's head is obviously much larger than that of an ostrich, which means that this guy's brain capacity is not too small, and the EQ is relatively high, which means that it is more intelligent, and Su Peng and the three of them can even see the look in the eyes of this huge chocobo, it seems to be observing these three It has never seen an animal.

Su Peng opened his eyes wide and looked at the huge chocobo for a long time before he muttered, "Brother Cai...... If I'm not mistaken, isn't this the extinct Titan bird on Earth? ”

"I also suspect that it is this prehistoric giant bird......"

Cai Junhua nodded and said, and then said: "Last time I came, I saw this creature, and I was also stunned at the time, but I didn't catch one myself to study whether it was the same as the species on the earth." ”

"But I quickly gave up on that idea...... There are too many such creatures in this mysterious basin, this kind of Titan bird is not unusual, and it may not be the kind on the earth, for example, the Titan bird on the earth may not be able to survive in the current temperature environment. ”

"In short, there are many magical creatures such as the Titan Bird in this secret realm, and even if I see a dinosaur here, it will not be surprising."

Su Peng listened and nodded, but he couldn't help but take a few more glances at this huge Titan bird.

"Let's go, although these titan birds are carnivores, they generally won't take the initiative to attack us when they are full, especially if we are still carrying torches, this thing is quite afraid of fire, but when you enter the jungle, you have to be careful, the danger of this jungle is not comparable to the primeval forest outside."

Cai Junhua said to Su Peng.

Su Peng listened, nodded, and glanced at the huge chocobo again, before walking towards the jungle with Cai Junhua and Liang Wei.

After a few people walked in the jungle for a while, Su Peng found that the biodiversity here was really not comparable to the outside.

The three of them walked less than five hundred meters, and Su Peng had already seen a colorful centipede about a meter long, a bit like a rodent in the dinosaur period, and a huge mosquito the size of a fist.

Plants are also strange, all kinds of wonderful, Su Peng saw a plant like a peach, from' Something like a flower heart stretched out from the tip of the peach, and then an insect that might have been the fist-sized size of a primitive bee flew up, and just about to do something, the peach-like plant suddenly opened its petals, and all of them were like giant mouths with teeth, and the primitive bee-like insect was swallowed in one fell swoop, and Su Peng could even hear the chewing and burping sound of the strange plant.

"It's really amazing......" Looking at all this, Su Peng couldn't help but think in his heart.

The three of them moved cautiously in the jungle, because this place was extremely dangerous, and the speed of the three of them was not fast, about half an hour, and they walked less than two kilometers.

"We seem to be in a bit of trouble."

When he walked two kilometers into the jungle, Liang Wei suddenly spoke.

Su Peng knew what Liang Wei was talking about, he glanced back, and saw that the huge Titan bird that the three of them had encountered when they first entered the secret realm actually followed all the way and followed behind the three of them...... (To be continued......)
