Lu Yuan found that his own divine consciousness could be explored in other places to a range of about 50 meters, but in the valley, his own divine consciousness could only cover a mere twenty meters.

This probing distance is not even as long as that of his eyes.

After traveling on the bottom of the sea for more than an hour, Lu Yuan did not find anything unusual for the time being.

Lu Yuan was not discouraged, and it was normal to find nothing. The ocean is so big, if you can see strange things everywhere, then the original strange things are not strange.

It's because it's rare that people are curious. If it's really that easy to find, it's not normal!

Lu Yuan acted cautiously, and he suddenly had a feeling in his heart that the king squid didn't seem to be far away from him.

As Lu Yuan walked, he suddenly felt that something was wrong, and the aura content in the seawater next to him had been rising.

"What's going on, is there a similar undersea cave here?"

Carefully feeling the changes in the aura around him, Lu Yuan found that the aura content in the sea water in different directions was differentiated.

After thinking for a moment, Lu Yuan decided to walk in the direction of a higher concentration of aura.

Passing through a dark submarine valley, Lu Yuan's eyes lit up.

Suddenly, a colorful scene appeared in front of me.

It's not like the darkness just now, but there are many glowing plants and animals here.

This place is so beautiful, Lu Yuan didn't know what words to use to describe the beauty of this place.

He took out his shooting equipment and prepared to shoot the surrounding environment, but he didn't expect that because the pressure of the sea water was too great, the camera equipment was directly crushed.

He had no choice but to throw the damaged equipment back into the Xiaoding space.

"It seems that next time we will have to prepare special deep-sea shooting equipment!"

Lu Yuan continued to move forward while enjoying the beautiful scenery.

At this time, he suddenly discovered that there were many kinds of underwater creatures living in this sea area.

Far more than anywhere else, and all of them were strange, nine times out of ten he had never seen them before.

Not only that, but these sea creatures, they are very large and very powerful.

Along the way, you will encounter ordinary fish, octopuses, crabs, shrimps, and even ordinary worms and plankton, which are larger and more aggressive than those in other places.

There have been several times when Lu Yuan has been actively attacked by them, and if it weren't for Lu Yuan's powerful witch body, I'm afraid it would be difficult for him to retreat under the attacks of these creatures.

Lu Yuan felt that this body of water and other waters were like another world separated by time.

He secretly raised his vigilance and continued to walk in the direction of a stronger and more active aura.

The further you go, the more powerful the underwater creatures you encounter.

Especially the giant shrimp that Lu Yuan had just encountered, the size was actually more than 2 meters, and the attack power was also very strong.

Lu Yuan saw it directly crush a stone.

If ordinary people are caught by it, they will definitely be cut into two sections.

This place was so weird that Lu Yuan began to wonder if he was still on Earth. He felt as if he had suddenly arrived in a world of monsters.

After going on for more than an hour. Lu Yuan stopped.

A tentacle appeared in front of him, and Lu Yuan wanted to use the Earth Escape Technique to sneak over to take a look, but found that perhaps because of the too much water pressure, there was no way to escape here.

Now he had to cautiously approach the tentacles.

It took him ten minutes to see what the tentacles looked like, and that's when he realized that something was very wrong with them.

"Could it be that one of the tentacles of the king squid has been broken here? ”

Lu Yuan continued to get closer, but the tentacles were still motionless.

He walked around a boulder, stunned by the sight in front of him.

What appeared in front of him was actually the corpse of the king squid.

After careful inspection, Lu Yuan was very sure that this corpse was the king squid.

Because there are many scars on its body that are clearly from the explosion.

"Could it have died from injuries sustained by the explosion of a warship?"

After careful inspection, Lu Yuan quickly overturned his guess.

He found that the scars from the explosion were old, and that it was a strange kind of wound that really killed it.

"What is the cause of this scar?"

Lu Yuan thought hard, the scars on the body of the king squid looked like they were formed by being entangled by something.

He looked thoughtfully at the tentacles of the king squid, "Could it be that there is an even more powerful king squid here!"

Lu Yuan's heart froze, and he looked around vigilantly, and then he noticed something unusual.

The carcass of the king squid is here, but no animal comes to feed it.

This is very abnormal, unless this is the territory of a powerful creature that makes other animals afraid to come. Thinking of this, Lu Yuan decided to leave for the time being.

When Lu Yuan turned around and was about to leave, his divine sense inadvertently swept over something strange next to the corpse of the Great King Squid.

Out of curiosity, Lu Yuan walked over and picked up the thing.

It was a strange little box, made of something that resembled jade.

Lu Yuan didn't take a closer look, and left after putting it into the Xiaoding space.

After walking out for a distance, Lu Yuan thought of something, and he turned back and placed several detectors around the corpse of the king squid.

After doing this, he returned to his original position and headed in the opposite direction.

Continuing to move forward, Lu Yuan found that the aura in the sea water had actually reached a terrifying concentration.

It has reached half the strength of the undersea cave, and it is very active.

Lu Yuan stopped and tried to absorb these auras for cultivation, but found that these auras all contained a violent aura.

In order to absorb and refine them, they must first remove that violent aura.

This situation was something Lu Yuan had never seen before, how could it be that the aura contained other breaths.

"Unless these auras have been used!"

Lu Yuan suddenly remembered the record in the jade slip.

Witches also need a kind of aura energy when they practice, and after these energies are used, other breaths will appear in them.

"Could it be that someone here is cultivating the witch body", Lu Yuan was taken aback by his own guess, being able to affect such a large area of the sea.

This person who cultivates the witch body is at least an official little witch.

Lu Yuan became more cautious in his heart, he resisted the urge to escape in his heart, and continued to explore.

At this time, a bottomless underwater deep hole appeared in front of Lu Yuan.

Lu Yuan was startled at first, and then took out the Wave Chaser Sword.

He cautiously walked to the entrance of the cave, the entrance of the submarine cave in front of him was very large, and Lu Yuan didn't know how big it was for a while.

The cave was not only large, but also very dark, and it lay quietly at the bottom of the sea, as if it were a gate to hell.

Lu Yuan was completely unable to detect the size and depth of the cave.

He carefully felt the aura around him. I found that the aura content in this place is actually richer than that in the sea water next to it, and the aura is more active and easier to absorb.

The concentration of aura here is several times higher than that in other places. It's almost the same as the aura concentration of the undersea cave.

He secretly wondered in his mind whether this underwater cave had something to do with the extraordinarily strong and active aura content in the seawater in this water.

To test this hypothesis, he decided to slowly approach the underwater cave. The closer you get to the entrance of the cave, the more intense the aura contained in the sea becomes, and the aura becomes more and more active.

When he came to the top of the cave entrance, the concentration of spiritual energy contained in the sea water far exceeded that of the undersea cave.

At this time, you can already clearly feel that streams of rich spiritual energy mixed with sea water are constantly gushing out of the cave.

You don't even need to actively absorb it, these auras will continue to nourish the body.

At this time, it suddenly dawned on him that it was no wonder that the creatures in this sea area were so huge, and it was all because of this cave.

At this time, Lu Yuan couldn't help but guess in his heart.

"Why is there a bottomless cave in the very flat seabed?"

"How did this deep hole come about, if it was a natural formation, the ground around it shouldn't be so flat. ”

"If it's not naturally formed, is it artificially excavated?" Lu Yuan just thought of this, and was immediately denied by himself.

You know, this is the bottom of the sea with a depth of nearly 2,000 meters, who can withstand such a large water pressure to make such a big project!

But then he hesitated again, because he suddenly thought of the witch decision he cultivated, "If it is the ancient Great Witch civilization, it is still possible." ”

But he quickly denied this speculation, because the energy of the Great Witch's cultivation was something else, and he didn't need aura at all.

At this moment, all kinds of speculations began in Lu Yuan's heart. A speculation arose, but was quickly denied by himself.

After thinking about it, I couldn't tell who had dug the hole.

It took a long time for him to calm down, and instead of speculating here, it was better to explore the cave first.

Maybe there is an answer in this cave, and Lu Yuan couldn't help but get excited again when he thought that he might be able to unravel a forgotten prehistoric civilization soon.

He took a closer look at the cave and found that the entrance to the cave was a very regular circle.

On it he found very obvious traces of artificial excavation.

At the edge of the cave, he also found something that looked like a road.

"It seems that this cave was really excavated by hand!"

But who would have dug this hole at the bottom of the sea at a depth of nearly 2,000 meters, and what was the purpose of digging it?

Endless questions rose in Lu Yuan's heart.

Lu Yuan walked around the edge of the cave, and the cave gave him a strange feeling again.

He felt that the cave was very similar to the pits of the Terrace Coal Mine he had seen before.

"This can't be a former mining pit!"

A bold guess came to his mind.
