In fact, the sound under the water is very chaotic.

But what can make Zheng Wenlou pay attention is that there is a sound of some kind of mechanical operation coming from the depths of the cave.

Such a discovery suddenly made him vigilant.

"Is it an engine?"

Zheng Wenlou stopped in front of the dark hole, and he could tell what kind of mechanical tool it was from the sound.

However, he rarely touches mechanical equipment, and can only tell that it is something like a diesel engine or an engine.

"It seems that it was the right thing to do to block the water outlet. ”

Zheng Wenlou frowned, because no matter what kind of machinery it was, it proved that there were signs of human infestation in the distance!

The only thing that made him feel at ease was that the sound was a long way from the dungeon.

"It's probably in the canyon on the southwest side. ”

After a little thought, Zheng Wenlou judged the approximate location of the source of the sound.

When he was looking for a place to retreat, he had several options to choose from, and the canyon located southwest of the Treant Valley was one of the areas for him to choose from, because there was also a water source there, but unlike the Treant Valley, the water source was located at the bottom of the canyon, a small muddy pool.

The canyon wasn't big, it was like an inconspicuous little wound in the desert, and if he was right now, it should be in the lower reaches of the underground river, or at least the water would pass through it.

"Did anyone show up in the canyon, spot the underground river and come in?"

"What is there that can be interesting in this place where birds don't?" Zheng Wenlou was full of doubts, because he really couldn't think of anyone who would be interested in the underground river and come in with mechanical equipment.

This is not a tourist resort, if the ordinary people get in, the slightest carelessness can kill them.

"It can't be a scientific expedition team, right?!"

Zheng Wenlou's face gradually darkened.

If it's a scientific expedition team, it's a big problem.

Those who are very exploratory will not be stopped by an underground river.

A set of professional diving equipment will allow them to enter the dungeon!

According to Zheng Wenlou's knowledge, in recent years, the government has worked the problem of sandstorms, desert greening, desert water diversion, soil transformation and other means have emerged one after another, and experts have long proposed a plan to take water in the desert, that is, to find underground rivers!

Regardless of whether it works or not, once a large-scale underground river and supporting underground karst caves are discovered here, I am afraid that a large number of geological experts, desert management experts will flock to it, and even the tourism bureau of Inner Mongolia will intervene.

As long as the conditions are right, the infrastructure madness will turn the underground river into a tourist attraction in an instant.

Zheng Wenlou thought about it, this place is really suitable.

.........

.........

"Looks like I'm going to take a look. ”

Zheng Wenlou only hesitated for a moment before making a decision.

Originally, he planned to block the water outlet, the sky is high and the emperor is far away, even if someone appears on the canyon side, he can't come here, but if it's a scientific research team, it's different, and the devil knows when those experts will find here.

If you can't do it below, you can also come from above!

Experts are very powerful creatures, maybe people can deduce the direction of the underground river from the soil topography or something, once they find the anomaly in the Tree Man Valley, then he and Xiaotong will not be at peace.

"If it's not for the research team, you're out of luck. ”

Since he decided to go to check the situation, Zheng Wenlou did not delay any longer.

Beckoning the strange beasts that followed, he cautiously burrowed into the cave.

The cave tunnel with a diameter of more than 5 meters can fully accommodate Zheng Wenlou's size, and at this moment he also has some expectations in his heart, that is, if the cave tunnel gets narrower and narrower, then there is no need to worry that outsiders will enter the dungeon from here.

However, after listening carefully to the movement in front of him, he shook his head helplessly.

Judging by the sound of the dark river flowing, the passage would only get wider and wider, and it would not appear the picture he was expecting.

"Hopefully I'm wrong. ”

Zheng Wenlou thought of the severed head, the scientific research team shouldn't be able to do such a thing, right?

Although he was skeptical, Zheng Wenlou still concentrated on sneaking underwater.

He hadn't forgotten the huge glass fish, and he wasn't surprised that a monster had popped up from under the water.

The further he swam, the larger the space became, and by the time he swam a few hundred meters, the diameter of the tunnel had reached more than 6 meters, which undoubtedly proved the horror of his hearing.

At this time, there were traces of vegetation on the bare underwater reef, and Zheng Wenlou used a fluorescent light to probe and found that it was a succulent plant that he had never seen before.

The gray-brown plant is a bit like the coral on the bottom of the sea, although the color is single, but it is also divided into several species, a large number of small fish and shrimp live in it, and even he saw a large black fish gnawing on these underwater plants.

"Can you eat it?"

Zheng Wenlou had a surprised look on his face, but the appearance of him and the strange beasts scared the big black fish away.

The size of this black fish has exceeded 2 meters, and the thick tail has already run far away.

Zheng Wenlou looked in the direction where the black fish had fled, and unexpectedly found that more huge fish lived under the water, among which there were many glass fish with a body length of one or two meters.

"So you grew that big by eating these things?" Zheng Wenlou didn't pay attention to the fish that fled because they were frightened, but focused on the coral-like plants.

He had always wondered how a glass fish of its size could survive, but now it seemed that there was a huge granary feeding it.

Zheng Wenlou stretched out his hand to pick a few plants and put them away, and when he went back, he could study them, at this time, as far as his eyes could see, there were such unknown plants growing everywhere, the further he went, the denser he became, maybe this plant had already been discovered by the plant world, but Zheng Wenlou was a complete layman, and it was reasonable that he couldn't recognize it.

"It seems that there is no need to worry about the danger of Stonehenge in the future. ”

Zheng Wenlou nodded.

Although a large fish appeared in the tunnel from time to time, it was not a threat to him and the alien beast at all, and if you thought about it, what danger could a tunnel with a diameter of only 6 meters be, no matter how big a creature could be stuffed in!

"Don't eat it, hurry up. ”

Zheng Wenlou couldn't help but cry and laugh a little when he saw that the alien beasts were also learning the practice of large fish and falling into the carnival of eating.

As he went deeper, when the diameter of the tunnel exceeded 8 meters, he could clearly hear the sound of mechanical work, the sound was very loud, and the rumbling sound could feel violent vibrations, and there was the sound of human conversation during the process.

Zheng Wenlou calculated in his heart.

It's almost a kilometer away from the dungeon, and it's infinitely close to the canyon.

"It looks like it's the front. ”

Zheng Wenlou quietly swam forward.

Ahead was an exit, and if he heard me correctly, there was a large underground lake outside, and all the fish that had been scared away had fled there.

"A dark passage linked to the waters of the dungeon, I don't know if the people above have found it. ”

Zheng Wenlou thought secretly in his heart.

However, just as he was about to approach the exit, he found a corpse in the corner of the tunnel.

"Corpses?"

Zheng Wenlou frowned, then leaned over to take a look.

This is a headless man, wearing a brand-name casual suit, and a string of jade Buddha beads on his wrist, which can roughly tell that this guy's net worth was good before his death.

In just a few glances, Zheng Wenlou had already determined that the corpse and the human head belonged to the same person.

"It's a good thing that the dungeon is upstream, otherwise it's not a good feeling to think that the water I drink every day has soaked the corpse. Zheng Wenlou complained, and then continued to check the wounds of the deceased.

"Sure enough, he was cut off by a knife, and it is rare for people to have this kind of arm strength. ”

Zheng Wenlou suddenly had a heartbeat.

If this guy was killed by someone above, it is very likely that he is a vicious gangster, not some scientific research team, of course, these two identities can also be combined.

A vicious scientific research team?

Go up and take a look.

Zheng Wenlou took a look at the strange beasts around him, restrained them from messing around, and then secretly swam out.
