Lin Lie spent a lot of effort, and finally searched the entire lake carefully, but he didn't find any hidden passages at all.

Those few carnivorous fish, Lin Lie couldn't eat them all, this can only show one problem, that is, this lake is connected to another place, and those fish are in that place in advance, so they can avoid Lin Lie's search.

But where is that place?

Although Lin Lie wanted to know the answer, he had to choose to put this matter aside for the time being, because it would be too much of a waste of his time.

The carnivorous fish that were missed were already very scarce, and they couldn't make any big waves at all, and he could usually eat them directly when he saw them, so he didn't have to kill them all in one go.

The reason why Lin Lie cared so much about this matter before was because this matter was really strange, which made him very curious. But now, if you want to figure out this matter, you will need a lot of time investment, maybe you can't find out the truth at all, then his hard work will only be in vain, obviously not worth it. Compared to this one, cultivating the iron cloth shirt is much more important.

That's why Lin Lie decided like this.

When he had eaten and drunk, he swam to the lair.

At this moment, a white light suddenly flashed from the water in the distance. Lin Lie's eyes were keen, and he could tell at a glance that it was a half-meter-long squid.

Seeing this ferocious carnivorous fish, Lin Lie would definitely not let it go. So, with a swing of his long tail, he quickly turned and swam towards the fish.

In the distance, the squid appeared close to Lin Lie.

Lin Lie had already become a nightmare for all the animals in this lake, and any fish would have to flee when they saw him, and this fish was certainly no exception. When it saw that something was wrong, it immediately wagged its fan-like tail and fled.

Squid are nimble and swim quickly. Even Lin Lie today can't simply catch up with it. However, if it is Lin Lie's explosion sprint, then it will not be too difficult.

The long tail swings, and the lake flows. After a while, Lin Lie caught up with the squid.

Seeing that the "nightmare" was getting closer and closer to him, the fish was terrified, and hurriedly tried his best to speed up, and suddenly swam away again.

Lin Lie hurriedly chased after him, and at this time, the fish was already close to the shore of the lake. Seeing that it had nowhere to run, Lin Lie was ready to pounce on it and slap it to death and eat it.

But who knew that the fish flashed quickly, and then disappeared into the darkness.

Lin Lie was surprised: "What's the matter, drilling into the mud?" ”

The black place was either mud or rock. When he saw the carp disappear there, he thought it had burrowed into the mud. But how can a squid drill into the mud? Is there something else going on here?

On this side of the lake, there is a small mountain on the side, and the continuous mountains form a semi-encirclement, which blocks the surface of the lake, and the sun does not shine here at all, so the light is very dim. It's even more eerie underneath the water.

Although Lin Lie's eyesight is very good, he will not be able to see clearly if he is a little further away in the water.

"It's strange, it's impossible for a squid to burrow into the mud, where the hell did it go? Could it be that this is the secret entrance to the passage, the one I've been looking for? ”

Thinking of these questions, Lin Lie hurriedly swam over and stopped at the last place he saw the carp. However, here he only saw a black rock wall, which was so hard that it was impossible for a squid to get into it.

For a while, Lin Lie was puzzled.

The water in this place is rocky and potholes, especially the light is very dim, and it is not easy to find it.

Before that, Lin Lie had always taken a look here and then left. But now, he realized that maybe this was the answer to the previous question.

It is impossible for such a big carp to disappear out of thin air, it is definitely swimming somewhere to hide, or it has gotten into a hole, and if he finds the carp, he will be able to find the answer.

So, he decided to do a good job of searching here.

But after a while, he didn't get anything.

Strange rocks were everywhere under the water, some in pieces, some in one piece, and the mud and rocks were mixed together, making it difficult for him to start. And the dark environment made his actions even more deadlocked.

But Lin Lie still refused to give up, and he continued to search.

A long time passed, and Lin Lie still didn't show up, which made his patience plummet.

"Maybe the carp has run away." In the end, Lin Lie had to think like this.

The water is very dimly lit, and the surrounding mountains block the light, so the sun doesn't shine here, all the time, and visibility in the water is even more pitiful.

Lin Lie finally had to give up the matter.

But just as he was about to go home, a remnant sun suddenly shone on.

"Why is there suddenly light now?" When Lin Lie was surprised, he hurriedly emerged from the water and looked diagonally upward.

It turned out that the afterglow of the remnant sun was shining through a crack in the mountains. If it weren't for this time, this angle, this weather, then this situation would not have arisen.

Lin Lie knew very well that the sun would completely set in an instant, and the afterglow would disappear soon, and the time for this lake to be illuminated was probably only a short ten minutes.

Before, Lin Lie's biggest obstacle to finding the carp was darkness, but now there was a ray of sunlight illuminating the lake, which made his vision clear and bright.

Lin Lie had already given up, but now that the situation was on the better side, he didn't care about those ten minutes, so he decided to dive into the water again to find it.

Under this search, he really found something amazing, an underwater passage more than one meter wide, and finally exposed to his gaze! Lin Lie was shocked by this!

The entrance to this passage is cleverly hidden under a few protruding rocks, and it is difficult to see even with the eyes, not to mention that there was no light before. This entrance almost blended in with the surrounding black rocks, and if it weren't for the light revealing some clues here, Lin Lie would not have been able to appear here.

Now that this mysterious entrance has been found, what's inside? Lin Lie's curiosity was aroused for a while.

At a glance, the passage was pitch black, and nothing could be seen, but Lin Lie still decided to go in and take a look, maybe something amazing could appear.

Before Lin Lie could enter the passage, the slanting light of the remnant sun disappeared, and the lake became pitch black again.

He swung his tail slowly and swam into the passage. Only three meters inside, he couldn't reach out for his paws.

His eyesight has always been very good, but in a completely lightless place, he must not be able to see.

Gradually, he went deeper into this passage, and Lin Lie unexpectedly realized that this place was amazingly big!

He groped and compared the size of the passage, and now it was thirty meters wide and seven meters high, it was a flat shape, and the length was still unknown. The reason why the entrance is so small is probably because most of it is blocked by mud and rock, and only a small gap remains, so it is impossible to see from the outside.

Moreover, he even saw that the walls were very smooth, completely regular, and a passage went straight inward.

This qiē only illustrates one problem - this is not a natural formation, but a man-made excavation!

What could be inside such a large artificial passage?

"Could it be that this is a national military base? A secret institute? Or the entrance to the tomb of some ancient emperor? ”

Lin Lie was even more curious for a while, and decided to go in and take a look. Of course, caution is a must.

In this way, Lin Lie touched his blindness, next to the wall, and slowly swam forward.
