Falling to the bottom of the sea, Xiao Hua looked around, this is more than 11,000 meters of seabed, surrounded by black lacquer Magu Cave, there is a dead silence, but Xiao Hua is an immortal cultivator, and he can still see the scenery within a radius of nearly a thousand meters.

"Huh? What is that? How can there be a large area of muddy stuff on the bottom of the sea? ”。

Xiao Hua found that somewhere at the bottom of the Challenger Abyss, there was a thick layer of whiteish turbidity, like a dark cloud in the sky, and it would slowly tumble and flow.

Xiao Hua swept it with his divine thoughts, and found that this layer of things that seemed to be slowly rolling like dark clouds could actually block divine thoughts, and his divine thoughts couldn't see through it, and he couldn't feel what was under the clouds.

"Huh".

Xiao Hua was curious, and with a push for the blister passing technique, he came to the top of this strange object.

This so-called "dark cloud" does not cover a large area, only a radius of nearly 100 meters, and the edge of the cloud is a rock protruding upward, at first glance, this layer of dark cloud looks like an oversized lid covering a hole in the ground.

"Is there something down here? Or is there room for something else? Hey, that's impossible? This thing is not a sealing enchantment or formation prohibition, and there is no spiritual power or mana fluctuation at all? ”。

Xiao Hua was a little confused.

This layer of turbid objects like dark clouds has no spiritual power attributes, and it is definitely not a seal prohibition, but why can it block his divine thoughts?

Xiao Hua became more and more curious, and with a mouth "poof", he spit out his five thunder balls, he wanted to try what this layer of turbid object was.

As soon as the mind moved, the five thunder beads turned blue, and then I heard "Boom", and a blue "Ren Qi Yin Water Mine" shot into the layer of objects that looked like dark clouds.

Sure enough, the unexpected happened.

Xiao Hua's "Ren Guiyin Mine" did not pass through the clouds and hit the ground at the bottom of the sea, but disappeared without a trace in the clouds and mist like a mud cow entering the sea.

Xiao Hua was happy in his heart, it seemed that the ground under this layer of clouds and mist was not the undersea ground, even if it was not a sealed space, at least it was a cave or passage where he could continue to dive.

But the question is, this layer of things can block the divine thoughts, what if there is danger below? Xiao Hua hesitated.

Thinking about it, thinking about it, Xiao Hua gritted his teeth for the last time, put away the five thunder beads and urged the blister crossing technique on his body, and directly plunged into this layer of clouds.

Since becoming an immortal cultivator, Xiao Hua's courage has become bigger, the cultivation of immortals is about chance, if you don't take risks, how can you get heavenly treasures and magic elixirs? In that case, it's better to give it a go.

However, as soon as he entered the clouds, Xiao Hua was stunned.

The temperature of this layer of cloud and mist is very high, at least it can be used to make tea, and because of the obstruction of divine thoughts, Xiao Hua instantly lost his sense of direction, and it felt like he had entered some magic circle.

Thankfully, however, there is no danger to this cloud other than that.

Without a sense of direction, Xiao Hua was a little nervous, but he knew that he had to go down, so he increased his mana and dived with all his might, and after more than a minute, Xiao Hua passed through this layer of clouds without danger.

Below the clouds and mist, there was another abyss, the water in this abyss was extremely cold, even more piercing than the sea water in the previous challenger abyss, if compared to that strange layer of clouds, it was completely ice and fire.

Xiao Hua gradually understood that that layer of cloud and mist should be an ancient enchantment specially used to isolate the divine soul, whether it was a divine thought or the essence blood divine soul used to connect with magic weapons and magic weapons, it would be isolated by it.

But the problem is, if this abyss is a sealed secret realm, then this layer of cloud and mist should also be a mana sealing prohibition, how can it be just an enchantment used to isolate the divine soul?

Could it be that this abyss is not an independent void sealed by mana, but a real space?

That ancient enchantment used to isolate all divine souls is a bit like a phantom array specially set up by the immortal hermit world in order to prevent mortals from entering by mistake, but it is not mortals who want to stop, but immortal cultivators?

Xiao Hua touched his bald head, but still couldn't figure it out, it seems that there are too many unknown things in this world.

"Whatever, anyway, if you come in, then take a look around, maybe there is a Gathering Spirit Grass here."

Xiao Hua began to mumble again, since this is also an abyss, maybe there are caves as well.

After that, Xiao Hua searched around in this new abyss hidden under the seabed, and it didn't take long for him to discover a huge underwater cave in this new abyss.

This cave was different from the ones he had previously discovered and searched in the abyss outside.

The largest of those caves before was only five or six meters in diameter and more than ten meters deep, and the diameter of the hole in this cave alone exposed on the mountain wall was already hundreds of meters, and the cave was even more black and unfathomable.

"God bless, God bless, there must be a spirit gathering grass in this cave."

Xiao Hua clasped his hands together and muttered, and with a push for the blister passing technique, he entered this huge underwater cave.

The roof and walls of this cave are covered with aquatic plants, and you can faintly see some huge stalactite hanging stones that protrude outward, and the further you go in, the smaller the cave becomes, and the boulders become more and more abrupt and dense.

Xiao Hua couldn't help but be happy in his heart, it seemed that this was a cave that was really submerged by the sea, and there was hope for his Gathering Spirit Grass.

After half a burnt incense, a fork hole appeared in front of Xiao Hua, Xiao Hua hesitated for a moment, and then urged the blister passage technique into the fork hole on the left.

Anyway, it's just two holes, the left and the right are the same, and the big deal is to check both sides.

However, as soon as he entered the fork in the cave on the left, Xiao Hua's mind immediately sensed that a huge object was swimming towards him quickly from the cave.

"Huh", Xiao Hua was stunned for a moment, quickly stopped and scanned again with his divine thoughts, and then found that it was only a large underwater creature that swam to him quickly from the cave, not a demon beast.

Sure enough, it didn't take long for a huge black shadow to swim through the darkness deep in this fork in the hole.

Xiao Hua fixed his eyes and saw that this huge black shadow was a megalodon more than twenty meters long.

Xiao Hua was shocked, wasn't the megalodon extinct a long time ago? How could this prehistoric beast that lived between 28 million and 2 million years ago appear here?

Could it be that this hidden abyss is really not a sealed Void Secret Realm, but a real space?

So, this hidden abyss is actually a lost prehistoric world?

The layer of white turbid object that was hidden at the entrance of this abyss was not some ancient barrier specially designed to isolate the souls, but just a super "thermocline"?

Xiao Hua's brain began to mess up again.
