"In the water"? Huang Yi raised his eyebrows, glanced at the snake girl in some surprise, and then set his eyes on the lake full of endless whirlpools, thinking in his heart.

The snake girl also looked at the vast lake, and said with a slight smile: "Yes, it's in the water, that place, it's really weird, this lake is full of endless whirlpools, it can be said that it's all because of that place"!

"Oh? What about exactly"? Huang Yi was dumbfounded, he didn't expect to be guessed correctly by himself, these terrible whirlpools on the lake were really formed because of something or a certain place.

"I don't know the specifics, let me tell you this, under the surface of this lake, there are endless large and small holes, the water in the lake, after entering those holes, it forms a whirlpool on the surface of the lake, but there are too many holes below the lake, I don't know where the water goes, before me, there are too many powerful beings in this lake, all of them have entered those holes, but they have never appeared, so, I want to find some smart humans to help me explore the endless holes under the lake, but unfortunately, No one can help me, it's all straw bales," said the snake girl, a little speechless.

Huang Yi listened to the words of the snake girl, his brows furrowed, he probably knew how vast this lake was, if the whirlpools on the lake were formed because of the holes below, it is conceivable that there are countless whirlpools on the lake, how many holes are there below, the most incomprehensible thing for Huang Yi is that there are so many holes under the lake, logically speaking, the water in the lake cannot withstand the passage of time, but the water level in the lake has no sign of decreasing at all, even if there is a water source entering the lake, this is also unreasonable, just imagine, A basin of water filled with holes. How can it hold water?

"Then why don't you go out there and look for humans to help you explore underwater? Smart people in the outside world really don't want too much", and said dumbly.

The snake girl rolled her eyes and said angrily, "You think I don't want to?" But the people outside are too dangerous, don't think that I don't know that there are strong people in every part of your human race, if I dare to go out, I am guaranteed to be killed by the strong people on one side of your human race. So, if there are humans on this isolated island, why should I risk the near and far?"

Shrugging his shoulders, Huang Yi knew that what the snake girl said was the truth, there were indeed many smart people outside, but if the presence of the snake girl went out, it was guaranteed that a strong person like the sea dragon would appear as soon as possible, either catch the snake girl or kill the snake girl. There is no third possibility, and the battle between humans and aliens has never stopped.

"You're saying that there were many beings in the lake that were more powerful than you before, and they all entered those caves and never came out again"? Huang Yi asked again.

"That's right, I remember what I just said, right? You still ask"? The snake girl didn't have a good airway.

Interracial beings are very simple, when they choose to believe in someone. In fact, it is easy to let down your guard and get along very well. At this time, Huang Yi and the snake girl were talking, and they couldn't see that they were still alive and dead before, and the reason was just an ethereal so-called cooperative alliance relationship.

"No, I mean, why do you run when there are people who are stronger than you who go into the underwater hole and never come out?" And shook his head.

"Hmph. What do you say about this, is there an inexplicable place in your house that you don't want to figure out"?

The snake girl's words made Huang Yi speechless, yes. Just like today's Black Mountain Fort, if there are countless criss-crossing underground spaces inexplicably, I'm afraid Huang Yi will also try his best to figure it out.

Now that he has formed an alliance with the other party, Huang Yi does not intend to break his promise, and said: "Okay, I'll go and see with you, but let's say it first, if there is danger, I will leave at any time."

The snake girl nodded, shook her head and said: "Just exploring the cave, in fact, there is no danger, it's just that what is behind the cave is the key, the problem is, there are too many underwater caves, many things are the same, the undercurrent is surging, like a labyrinth, you can't go to the source of those caves at all, often enter a cave, you will be guided by the water flow out of another cave, all these years, back and forth I have not been able to enter the source of the cave, well, Even if so many of the men in the lake were allowed to explore the cave together, it ended in failure."

After listening to the words of the snake girl, there was silence, and the thoughts were churning in his mind, and he probably came to two conclusions, first, the underwater caves crisscrossed and led to a certain place, but there were only one or several real entrances to that place, which were hidden in the labyrinthine underwater caves, and the second conclusion was that the caves were extremely dangerous, not only could they be lost in them, but they also might have to face unknown dangers.

The danger of the second conclusion is the most vigilant, after all, it is underwater, if he is a human living on the ground, his combat effectiveness will be reduced a lot, and his survivability will be greatly challenged!

There are too many dangerous and strange places on this earth, and after more than ten years of changes, no one knows what dangerous areas on this earth, and there are too few places occupied by humans.

"What? Scared"? The snake girl looked at Huang Yi and asked.

Shaking his head, Huang Yi said: "No one doesn't cherish their lives, but I have promised you, let's go and see, I don't know if I can help, I can only say that I tried my best."

"Then let's go, don't worry, with me, the mutant beasts in the water won't attack you", the snake girl said, and it was also very simple, and after saying that, she took off into the air and shot towards the lake.

Huang Yi followed, and the two of them rowed through the void, several kilometers deep into the lake, and were about to enter the turbulent area, when the snake girl went down, and planted towards a huge whirlpool that was directly at least three hundred meters, as if swallowed by the whirlpool.

Huang Yi was not ambiguous, he followed the other party a few meters behind him and entered the whirlpool, his strength reached the point of Huang Yi, survival in the water is actually a very simple thing, it is no problem to hold his breath underwater for a few days and nights, but even so, his actions in the water will definitely be affected, and he is not as free as the ground.

When he went deep into the whirlpool, the swirling wind was like a knife, but it didn't hurt Huang Yi in the slightest, but after entering the whirlpool, the swirling water was torn into Huang Yi like a meat grinder, but fortunately, his strength was strong, and it couldn't affect him.

The visibility in the water is very low, and Rao is Huang Yi's eyesight, and he can only see things dozens of meters away, and he can't see it any further. There was no need to exert himself at all, and the downward surging water took Huang Yi and the snake girl towards the bottom of the lake at a high speed.

When she was about to reach the bottom of the lake, the snake girl's body swayed, breaking away from the swirling current, and when she reached the side, Huang Yi also broke away from the swirling current and followed her.

More than ten meters in front of them, there was a whirling whirlpool of water, and below the whirlpool, there was a dark hole mouth with a diameter of more than ten meters, like a hideous mouth, devouring the countless lakes, and the violent water flow, as if it was going to swallow both Huang Yi and the snake girl.

In the water near the bottom of the lake, although the sight was not very good, Huang Yi still saw that the irregular ground was full of large and small holes, like a rag full of holes, and those holes were the source of countless whirlpools on the lake.

In the water, Huang Yi can also see countless huge mutated creatures in the water swimming, huge pythons, fish, old turtles, shellfish, aquatic plants, etc., each of which can bring a deadly threat to people, but because the snake girl is on the side, the mutated creatures in the water did not come to attack Huang Yi.

"I'll show you the bottom of the lake first," said the snake girl, her voice strange in the water.

Huang Yi nodded, followed the snake girl around, and observed the terrain along the bottom of the lake, in fact, mainly to observe the countless dark hole mouths.

This lake is very deep, the water depth is at least more than 300 meters, this is not counting the depth of the water in those deep underwater ditches, the surface of the bottom of the lake, full of large and small holes, swallowing the endless flow of water in the lake, but after seeing many places, Huang Yi found that many holes are spitting water outside, probably guessing that most of the large and small holes at the bottom of the lake are actually connected, and some holes swallow the lake water, but they come out from other places, and so on.

Huang Yi also found that these holes are a bit less like natural formations, and many places can see traces of fractures on the surface, and those whirlpools are exactly where they are broken.

The more I look at Huang Yi, the more frightened I become, if these large and small whirlpools are huge fortifications buried underground, then who has already done all this in this defense of hundreds of square kilometers underground? These holes are obviously a long time old, and they definitely didn't appear after the end of the world, so, in the distant past, who dug so many holes underground?

The snake girl took Huang Yi for almost a day, roughly walked around the bottom of the lake, and for a whole day, kept swimming, Huang Yi saw too many strange water creatures, of course, the main thing is to observe the terrain.

"How"? About a moment later, the snake girl stopped and asked Huang Yi.

"It's shocking, these caves are obviously not naturally formed, but with countless caves covering hundreds of square kilometers underground, I really can't imagine who or that kind of creature can create such a spectacle," Huang Yi said with a solemn face.

Things are not simple, Huang Yi has a premonition that the other side of these caves must be hiding some kind of earth-shattering secret, which makes him feel the crisis at the same time, but also a little excited and expectant, human beings have always been full of curiosity about unknown things, and Huang Yi is no exception.

"So, can you find the real hole? I mean the real entrance to the other side of the cave", the snake girl asked expectantly, looking at Huang Yi expectantly...... (To be continued.) )
