Lucius's instinct was still there, and as soon as he entered the sea, after being affected by the strange sound of the sea, he immediately shouted and screamed, waving his limbs desperately to hit the sea, his face was painful, and he didn't want to stay in the sea water at all.

However, the strange sound made when the sea water collided with the rock wall had already deeply affected him, and the flat area of the sea water was very large, even if it was fast, it would take time to swim to the shore, not to mention, after being attacked by the soul, Lucius had already struggled into the sea inside.

"There seemed to be a force pulling Lucius at the bottom. ”

Lin Xi watched the movement closely and told the Mad Shura what he saw.

"The depth of the sea is about three thousand meters, and my vision is blocked at about a hundred meters, so I can't see what is going on below, and let's see how deep Lucius can sink and then make plans. Lynsey continued to star.

Soon, Lucius's struggle slowed down a lot, and the whole person had sunk to a depth of more than eighty meters in the sea.

With Lucius as a reference, even if his vision is blocked, he can see clearly.

About one hundred and fifty meters away, Lucius remained motionless, and there was no further movement.

"Dead, Lucius is dead. Lindsey said.

"Died less than two hundred meters away, it seems that ordinary Sea Clan people really can't go deep into the bottom to find the answer to the strange sound. Mad Shura sighed.

Although Lucius's strength was affected by serious injuries, Lucius was roughly equivalent to the level of an eighth-order human martial artist, however, Lucius's crazy struggle was gradually affected and pulled by a strange force, and finally died in the sea water at a depth of one hundred and fifty meters!

It is conceivable that if a sober eighth-order martial artist goes deep into the seawater, it will probably be difficult for him to break through to a depth of four hundred meters!

And according to the most intuitive estimate obtained from Lucius, at a depth of three thousand meters, if it is a sea tribesman at the lord level in the sea world, I am afraid that it is really impossible to penetrate to the bottom, and if it is impossible to penetrate deep into the bottom to eliminate the strange sound and inexplicable traction, then naturally, these people will be affected and die inside.

"However, this result is still within the range we can bear. Lin Xi's demeanor was more relaxed.

Because he is actually equivalent to the strength level of the early to mid-stage of the Demigod Realm, plus the strength of the Crazy Shura is already at the peak of the middle stage of the Demigod Realm, it should not be dangerous for the two of them to go deep into the bottom of the interior of this Shura Mountain together.

The black broken knife black light came out, and the mad Shura quickly walked out.

"Let's go down. "Crazy Shura didn't look nervous at all, but was full of enthusiasm to try.

With a jump, the two jumped into the water.

"I'll feel the movement on the surface of this sea first. Lindsey said.

The sea water seemed to be invisibly shaken, and it was constantly vibrating against the rock wall, and what should have been a soft and soothing crashing sound has now become an extremely uncomfortable sound that makes people's heads dizzy!

"I'll also see if this rock wall is boring. Wild Shura then swam to the side.

For Lin Xi and Mad Shura, the impact of the surface sea water was almost negligible, and now their minds were very clear.

Lin Xi picked up a handful of seawater, put it in the palm of his hand and looked at it carefully with his eyes, and after a while, Lin Xi put it down.

"No matter how much I investigate, the waters are exactly the same as the ones outside, nothing special. ”

With Linxi's current strength, it is enough to see the internal composition of the seawater, and compare it with the seawater outside, if there is anything different about the seawater here, then the situation will definitely be found.

At this time, the mad Shura next to the rock wall also said, "I found that the rocks here are very ordinary, at most they have survived for a long time. ”

"It seems that there is nothing wrong with the sea and the rocks, and the reason why the sound of the collision has changed so much is that I guess it has something to do with something that exists on the bottom of the sea. Lindsey said.

Mad Shura nodded, and then began to go deeper.

Lynsey followed.

There was no danger in the first hundred and fifty meters, and Lindsey only felt a little dizzy in his head, and at this time he was already next to Lucius's body.

Lucius's body neither floated nor sank, as if once he died, he would be bound by some kind of power and fixed at this depth, Linsey carefully checked Lucius's expression before he died, and found that Lucius was indeed not attacked and died, but completely died due to extreme fear that he had been attacked by the soul.

In other words, the strange voice killed Lucius.

"Further down. Lynsey continued downward.

It wasn't until 1,800 meters that Linsey stopped.

Mad Shura stayed by Lin Xi's side, and both of them had expressions that were a little painful and uncomfortable.

At this depth, the ubiquitous and strange sound was already really affecting them.

"The further down you go, the stronger the weird sound gets, which is clearly at odds with the general truth. Madness Shura said with a frown.

Even though his soul protection ability was stronger than Lin Xi's, and at the level of the Demigod Realm, it was already very strong, but he still felt the pain of being pricked in his head.

What's even worse is that even if he hides in the inner space of the Broken Knife, this sound will affect him in the same way, which is why he and Lin Xi have not entered the internal space of the Broken Knife, and let the Broken Knife sink.

Lin Xi nodded: "It is indeed inconsistent with the facts, according to common sense, only the surface and very shallow sea water have obvious shocks, and the strange sound is produced by the shock, but down there, especially under the water of a few hundred meters, the frequency of the sea water shock is already very low, and now we feel that the sea water around us is almost no longer flowing, but the strange sound has always existed." ”

"So I suspect that the strange sound is not caused by the vibration of the sea and the rock wall at all, but only at sea level and in very shallow areas of water. ”

Whether it is Lin Xi or Mad Shura, they have already discovered a position below 1,800 meters, and only then can they uncover this secret to figure out why that strange sound persists.

"Lynsey, we have to be careful, we can't dive at that high speed anymore. "It is very rare for the wild Shura to show a cautious look on the ground, and it is obvious that he is also a little afraid of the unknowable dangers that exist at the bottom of the sea.

"Of course. Lynsey agrees.

Although they didn't find any creatures attacking them all the way down, and the sea water was normal, the only thing that affected them was the strange sound, but it didn't mean that there were no other creatures attacking them.

"Our soul strength should be strong enough to support the bottom of the sea, so let's slow down and dive. After saying that, the mad Shura began to dive further.

From 1,800 meters to 2,100 meters, the two stopped again.

"I really want to go out and breathe. Mad Shura sighed.

Lin Xi also frowned, his expression was very uncomfortable.

Although the strange sound could not really plunge them into a madness, their consciousness was still awake, but the feeling of pins and needles in the head persisted, and it became more and more intense, and anyone who stayed in such pain for more than five hours in a row would definitely feel uncomfortable and irritable!

If you want to go out to breathe, it is naturally a reasonable thing.

"Now that we're here, I can only grit my teeth and hold on. The mad Shura then laughed self-deprecatingly and began to dive again.

After the two learned the "Breathing Method", they can already live in the sea forever like the Sea Clan, which can be done, and they don't have to really surface to breathe.

"If only Noah's Ark could withstand these sounds. Lynsey sighed.

Noah's Ark has also been tried, there is and there is no is the same thing, and the unique material of Noah's Ark can't attenuate the weird sound in the slightest.

"I really don't know what the bottom of this Shura Mountain is like. Lin Xi muttered as he dived.

Finally, both of them reached a depth of 2,300 meters.

However, the light emitted by the night pearl he carried with him showed that there was no seawater underneath!

Near the dividing line, the two of them could clearly feel that they were in the sea, but less than ten meters under their feet, there was transparent air, and there was no seawater at all!

This subversive scene is simply amazing!

You must know that the infinite gravity of the sea water alone will fill the interior of Shura Mountain with sea water, but the scene in front of me is not like this!

This weird dividing layer!
