The black silk shadow is something separated from the body of the Void Demon Race, not to mention its power, it can be described as an invincible existence in this true mortal realm.

Therefore, Li Muyun used the black silk shadow to surround the sea area in front of him with a radius of tens of meters, so he didn't have to worry about the black-robed demon cultivator escaping, of course, provided that the other party was really in the location indicated by the information from the black silk shadow.

After wrapping up the suspicious area, Li Muyun personally entered the sea shrouded in black silk, and then his divine sense probed out and carefully searched for all suspicious places, but after searching back and forth for a few times, Li Muyun still found nothing.

This is an ordinary sea area, and the sea water is constantly flowing, if there is anything special in the sea water, it will definitely not be intercepted by the shadow of the black silk, and the only thing that can pass through it can be ordinary sea water.

But in this sea area, the black silk shadow stained on the black-robed demon cultivator still kept sending messages, and the location of the message was here, which made Li Muyun frown and feel a little depressed.

Just when Li Muyun was confused and couldn't find the results, his divine sense moved, and he found that two krakens were swimming in the sea from afar.

The two krakens have completely transformed, obviously they are at least demon cultivators at the Dan Realm level, both of them are young men, except that the clothes they wear are not quite the same as the style of humans on land, the rest are no different from humans on land.

"Who are you, dare to invade the sea field of the black-robed ancestor!"

The two krakens were extremely fast, and they had already swam in front of Li Muyun in the blink of an eye, and immediately asked Li Muyun.

"The black-robed ancestor you are talking about is a demon cultivator in a black robe, right?" Li Muyun asked without answering.

"Bold! Can you find out the identity of the ancestor? Hurry up and report your name and tell us why you forcibly broke into this core area, we will intercede with the ancestor, maybe we can save you from death!" Among the two krakens, the taller one immediately shouted at Li Muyun.

"I'm too lazy to talk to you!"

Li Muyun lost the idea of continuing to inquire normally, and directly took action, trapped the two with black silk shadows, and then forced them to ask about the situation of the black-robed demon cultivator.

With the gradual mastery of the black silk shadow, Li Muyun felt more and more that this black silk shadow was really a rare and wonderful means.

At this moment, the black silk shadow turned into many segments, like black ropes, wrapped around the wrists and ankles of the two krakens, making each other unable to move.

After this black silk shadow turned into substance, it was harder than any object, and it was almost immune to spell attacks and physical attacks, because the black silk shadow was a part of the Void Demon Clan, and it was a void substance.

At first, the two krakens were going to be hard-mouthed, but under Li Muyun's torture, they finally couldn't bear it anymore, and began to pour beans into the bamboo tube, and talked about the black-robed demon cultivator.

It turned out that the black-robed demon cultivator, who claimed to be the black-robed ancestor, came to this sea area a hundred years ago, and after subduing several powerful krakens at the bottom of the sea, he established this territory in the depths of the sea area.

After Li Muyun dived, he walked all the way around the periphery, and the place he surrounded with a black silk shadow was the gateway to the real core area, which was not established by the black-robed ancestor, but a means that only the Kraken clan could master.

The portal is hidden in the sea, and as long as there is seawater, the portal cannot be discovered, and even if you can feel the existence of the portal, it will not be able to make the portal show its form, which can be described as an extremely powerful means of concealment.

"As long as there is seawater, the portal can be hidden and undetected?"

When Li Muyun heard this, he immediately asked, "Then what if the seawater here is discharged? Forming a small vacuum area that is large enough to encompass the entire portal, will the portal be able to function?"

"No, unless you empty all the water here, the portal will not be able to be activated and will not be perceived. ”

The tall kraken, who called himself Yu Xiaoyu, said, "The only way to find the portal is through the prismarine and the spiritual formula, and I can't think of any other way to find the portal and get in." ”

"What is prismarine, and what is the formula? Li Muyun asked.

"Prismarine is a kind of spirit stone that is a specialty in the sea, in the sea, where the aura of heaven and earth is strong, it will form a sea spirit eye, just like those spirit veins on land, the spirit veins can be mined out of spirit stones, and spirit eyes can also condense sea spar. ”

Yu Xiaoyu explained, "Only the prismarine, with some of the sea clan's spiritual formulas, can summon the portal, and then pass in, there are three prismarine on my body, and the specific formulas and gestures of the spiritual recipe are ......"

After Yu Xiaoyu's introduction, Li Muyun also mastered the method of opening the door of the black-robed ancestor's black-hearted territory.

After getting the method, he immediately searched for three prismarine stones from Yu Xiaoyu, and then regardless of the two of them, he directly cooperated with the prismarine and played the spirit trick.

Soon, it was originally just a piece of seawater, and a translucent blue gate suddenly appeared, the gate was five meters high, about three meters wide, the frame was made of dark blue translucent jade, and the two gates were also blue jade texture, which looked very fragile.

The blue door is very simple, there is no door plaque, no ornamentation, and there is nothing else behind the front door, it is a simple portal, which is similar to the arbitrary door in the comic "Doraemon" that Li Muyun read in his previous life.

"Can you enter by opening this door directly?" Li Muyun turned his head and looked at the two krakens and asked.

"Yes, because the portal is hidden enough to summon the portal, only the high-level inside the Sea Clan, outsiders can't summon the portal, so as long as the portal comes out, there is no need to arrange any defenses. ”

Yu Xiaoyu replied, and then said, "The two of us have already told everything we know, won't Your Excellency let us go?"

"Wait!"

Li Muyun said casually, and then directly pushed open the blue door in front of him.

The blue jade-like door slowly opened, revealing a pale blue curtain of light inside.

This place is thousands of meters away from the sea, and the water pressure is very huge, but the sea water does not press towards the light curtain revealed on the portal, Li Muyun has a halo open, and he is not worried about any accidents, so he directly passed through the light curtain and entered the blue portal.

The light blue light curtain was like a watershed, Li Muyun was still in the deep sea a moment ago, and after passing through the blue light curtain, he was already in front of a huge palace.

The palace is located on a circular area, outside the palace, there is not much space, the whole palace can be said to be located in a cylindrical space, and outside this cylindrical space, it is deep black, as if there is no light in the deep sea, the darkness is deep, and it is daunting.

The palace is very huge, there are four krakens guarding at the gate, all of them are holding weapons in their hands, and their cultivation is not high, only in the qi realm.

Li Muyun was at the door of the palace at the moment, he looked at the majestic palace, and looked at the few big characters written on the plaque on the door of the palace - Heixuan Palace.

And as soon as he entered here, Li Muyun found that the message from the black silk shadow on the black-robed ancestor was obviously clearer, obviously, the black-robed ancestor was in this palace.

"What people!"

Facing Li Muyun who suddenly appeared, the four guards at the gate of the palace were suddenly taken aback, and they all aimed their swords at Li Muyun, and then asked him.

With the doorman's questioning, the corner gate next to the huge black gate was suddenly pushed open, and a group of eight krakens walked out of the corner gate one after another, and Li Muyun was surrounded by the group.

The strength of these krakens has been raised to a higher level, all of them are fully transformed Dan realm demon cultivators, looking at the weapons in their hands, some of them are flashing with light, exuding faint spiritual power fluctuations, obviously magic weapons, stronger than the ordinary weapons in the hands of those krakens of the qi realm, I don't know how much.

However, before Li Muyun could clean up these miscellaneous fish, the gate of the palace suddenly opened, and the black-robed ancestor shot out like an arrow, standing in front of Li Muyun.

"You still dare to chase after you! Do you really think that I am not your opponent, do you?" The black-robed ancestor waved his hand and let those krakens retreat to the palace gate, and then looked at Li Muyun with a sneer and said.

"You've been there fast enough, I thought you'd show up after I cleaned up your minions. ”

Li Muyun smiled faintly, then his face turned cold, and his eyes looked at the black-robed ancestor, which was already mixed with anger, "But it's better to show up early, so as not to wait for you to continue to escape." ”

"Hmph, I do admit that your black silk is very powerful, I don't know what kind of magic weapon it is, but if I don't arrange defensive means, just use fast movement to dodge your attacks, I want to know, can you still touch me?" said the black-robed ancestor disdainfully.

"You'll know if you try it. ”

After Li Muyun finished speaking lightly, he stopped talking nonsense with the other party, and continued to wave his hand to emit a black silk shadow.

This time, he didn't send out only one like last time, but sent out countless ones, and suddenly, a black silk swept towards the black-robed ancestor like a black tide, and the black silk shadow was enough to almost seal the space that the black-robed ancestor could dodge, and he could only go up to dodge.

This scene suddenly startled the black-robed ancestor, he originally thought that the black silk shadow emitted by Li Muyun should be an attack issued by some powerful magic weapon, like an attack that even a cultivator of the divine realm like him could easily break through, obviously the grade of that magic weapon was not low.
