It is very difficult for the Yan Kingdom and the Lu family to find a way to establish contact with this undersea city. Lu Qing estimated that the distance between the two parties to love you is actually very far away, and they are still under the deep sea, and it is very difficult to communicate.

However, there are still ways to think about this matter later.

At present, the first thing is to figure out the aura current.

This ocean current, within the city, is obviously also a very important thing. The people of the underwater city are obviously built around this ocean current that goes west. In other words, this aura current is equivalent to the main road of the city and the main artery of the whole city.

Lu Qing continued to move forward, and soon followed the special passage of the ocean current to the center of the undersea city.

It's really the most important core area of the city, rightly so.

A huge, circular castle, located here, looks heavily guarded, wrapping the central area tightly. There are many rooms and terrace-like places on it, guarded by Sea Clan guards wearing gold-blue armor.

Except for the aura current, which left an opening and flowed out of it, it was completely incommunicative with the outside world.

Lu Qing didn't rush into it from the aura current, he first explored from the periphery, and then found the guy who looked like the ruler of this underwater city.

Sure enough, it was a sixth-order powerhouse.

His image is like a creature like an octopus or a squid, transformed into a half-human form. He had a torso and legs, but his hands and feet were about elbows, and his eyes were full of tentacles. His head, like a giant octopus, was just a beard and a lot of tentacles grew from his chin.

Lu Qing also noticed that on his head, he was wearing a crown. How can the appearance of this crown be exactly the same as the sea crown generated by the previous system by giving rewards, but it is many, many times larger?

In addition, Lu Qing also noticed that there was a golden-blue halberd in his hand. From it, Lu Qing could feel that there was an aura similar to the Deep Sea Scepter, but much more powerful than the Deep Sea Scepter, coming out of it.

The halberd, including the huge crown that sits on the octopus's head, may have been similar to a holy artifact?

The size of this octopus man is very huge, and it is a little smaller than the monk who has opened the state of the law phase, and most of the space in the core castle is occupied by him.

It was precisely because of this that Lu Qing was able to find him very easily after entering.

But be careful, this is not the regular state of people, if he also goes all out and incarnates into the Faxiang, then the ghost knows how big it will be in the end.

It turns out that in the deep sea further east of Tokai County, there is such a sea overlord hidden......

However, looking at this guy's lazy appearance, he doesn't look like a guy who likes to go out and stir up trouble.

Without looking any further, Lu Qing retreated, found the aura current again, and headed towards the interior of the central castle.

And then, Lu Qing knew why the octopus man, who seemed to be the overlord of this underwater city, only lived on the surface of the castle and did not enter the innermost part.

It's simple: he can't get in.

At the core, this is a secret realm that has been banned by the forbidden law!

Moreover, this ban is very powerful, so much so that Lu Qing can feel the horror very deeply when he stands on the edge. Lu Qing couldn't figure out the level of power of this ban, but it must be stronger than the law phase, which he was sure of.

That old octopus king, because of this, can't get in, it's normal.

At the same time, Lu Qing also keenly felt that the power of this ban was quite ancient.

This reminded him of the Swire series.

Anyway, in the current generation, he had never heard of any power in the world that could transcend the level of the Faxiang - maybe Lu Qing didn't have enough knowledge now?

All the things he saw that could reach the level of transcending the Dharma were from the primeval period.

Come to think of it, this one is probably no exception.

Lu Qing didn't think that the ban here was made by those sea clans outside. This matter should be the other way around, those sea tribes should be because of the ban here, resulting in a large amount of spiritual energy gathering, so they built a city and lived here.

Then, Lu Qing also sensed the fact that the huge amount of spiritual energy that leaked out and formed an ocean current did not flow out of the secret realm, but from the forbidden law.

In other words, this forbidden method that sealed the secret realm was itself in a state of damage, and its power was passing by every moment.

The power of the passage of light can form such an area equivalent to a sixth-order spiritual vein in place, which is enough to support a city that is even larger than Yandu. Moreover, this unstoppable spiritual energy leaked out, and even flowed from the sea to the land, forming an underground dark river, and even almost crossed the entire Feiyun Prefecture from east to west, and after reaching the position of the Jade Smoke Mountain, it was still able to retain the strength equivalent to the third-order spiritual vein, which was actually very exaggerated.

But even so, after such a long time, the seals around this secret realm are still so strong. One can imagine what it would have been like if it had been at its peak.

And it is precisely because of this that Lu Qing is more interested in this secret realm under the primeval seal.

He wasn't sure if he would be able to break through the seal and get into it.

Of course, he can directly ignore the general forbidden law, but he has experienced being forbidden to enter by the forbidden law left over from the primeval period, and now he doesn't know what will happen.

But give it a try, you won't have too many problems, right?

Of course, when it comes to something related to Swire, it's always right to be careful.

Lu Qing's actions were very cautious. He approached step by step from the location of the aura current channel.

In the process, he didn't feel any obstacles.

The entire forbidden law, in the form it shown, was like a huge blue sphere of light, wrapped in the undersea CITIC Castle built by those sea tribes outside.

Lu Qing entered the ball of light without any obstacles.

But it wasn't that he didn't feel anything at all—he felt like he was soaking in a stream of cold water.

It stands to reason that he should not have this feeling in the state of consciousness, and once this happens, it is basically certain that it has something to do with the immortals of the primeval era.

It's just that he didn't feel any threat or malice to him from this coldness.

So he went on.

In this ball of light, that is, the center of the forbidden law, Lu Qing saw a pure black door, and an ominous meaning came out of it.
