It can be said that this crazy general Zhennan has done a perfect job in hiding this underground tomb city, but his idea of being an underground ghost king has still not been realized.

Although he almost completed all the preliminary preparations, he killed his descendants with a special method and turned into a ghost grandson.

He refined his legion into the Ghost King Legion, and he transformed the souls of countless ordinary people after death into the ghost people of his Netherworld.

But he forgot one thing, the instability of the Demon Dao Exercise was too much, and as a result, in the Zuihou step, he himself had a demon skill that was devoured, and he was scattered, which was naturally a bamboo basket for water.

At the same time, those heirs who were transformed into devils and ghosts by him, because they were too close to him, were also regarded as enemies when his magic skills were confused, and they were killed.

This change has made this well-built underground mansion a borderless place.

Originally, according to General Na Zhennan's plan, his underground ghost kingdom would be cultivated for at least hundreds of years, and only after he had a certain strength would he open the ban on this ancient tomb city and reappear in the world with the demeanor of a generation of ghost kings.

So he set up a ban at the beginning, and no one but him could open the closed ban of this underground tomb city.

This underground tomb city is in an absolutely closed state, of course, through the prohibition set around the underground tomb city, it will also attract a strong cold ghost aura and aura to meet the needs of this Zhennan general to build an underground ghost country.

And now, the general of Zhennan didn't explain anything, so he left west, leaving behind a plate of scattered sand in the ancient tomb city.

This led to chaos in the entire city, and in the end, thirteen ghost generals under the Zhennan general split off, each of which seized one side of the underground tomb city and fought with each other.

But because of the forbidden protection, the other ghost generals, ghost soldiers, and ghost people in this underground tomb city, although they have lost the owner they will guard, are still trapped here and cannot leave.

At the same time, this underground tomb city with the development direction of the Netherworld Mansion also has the effect of attracting ghosts, so in the next few years, I don't know how many heaven and earth spirits have been attracted, but it has allowed those ghost generals who have enjoyed the power for I don't know how many years.

Previously, Zhu Lingwu asked the Xuanming Ghost Head to practice the Earth Escape Technique, but he could discover the existence of this underground tomb city, perhaps it was the effect of this special effect of attracting wandering spirits.

The soul clone in the head of the Xuanming Ghost is attracted by this underground tomb city, so that its existence can be discovered, otherwise it may not be able to detect this underground tomb city.

This situation has lasted for thousands of years, and the ghost generals who were imprisoned in this underground tomb city, although they also relied on the ghost energy and aura sent by the ancient tomb ban, they instinctively had not weak strength, but they did not know any ghost cultivation techniques.

Although the general Zhennan refined all the legion generals under his command into ghost generals and ghost soldiers, he did not pass on the ghost cultivation technique, so after his soul was scattered, these ghost generals and ghost soldiers who grew up spontaneously could only rely on instinct to absorb ghost qi and aura and condense their own ghost bodies.

Although it can also be compared to ordinary monks, it is not a terrible ghost master after all.

Then, I don't know how the people of the Xuanming Sect discovered this underground tomb city, although this underground tomb city is in the territory of the Jinyang Kingdom, and it is not the territory of the Xuanming Sect.

However, the Xuanming Sect still dispatched all the strength of the Xuanming Sect at that time, and the masters of the Yuan Infant Stage and the Jindan Period shot together, destroying a guardian prohibition in this underground tomb city, and forcibly entered this underground tomb city.

After that, the Xuanming Sect took advantage of this to make a windfall, and used their means to capture those ghost generals and ghost soldiers who grew up naturally, and they were all refined into Xuanming Ghost Servants of the Xuanming Sect.

After that, the Xuanming Sect even turned this underground tomb city into a secret realm of trials, and every ten years sent its disciples to come here remotely to conduct sect trials through the teleportation circle they set up in the safe area of this underground tomb city.

This process of trial can help the Xuanming Sect to grasp some newly grown ghosts with a certain strength into the impermanent ghosts that these Xuanming Sect disciples need, so as to avoid the natural growth of powerful ghost generals and ghost kings here.

At the same time, the Xuanming Sect can also collect all kinds of ghost materials that have been nurtured by ghosts and spiritual qi in an underground tomb city.

This underground tomb city has become an extremely important secret treasure place of the Xuanming Sect, refining various ghost methods for the Xuanming Sect, providing an endless supply of ghosts and materials.

Of course, since the Xuanming Sect was completely wiped out by the Ten Thousand Swords Sect of the Great Jin Dynasty as a demon sect, this Xuanming Sect's trial secret realm was once again buried under the mountain.

Because this underground tomb city is not on the territory of the Xuanming Sect, the disciples of the Xuanming Sect only know that this trial secret realm exists, but they never know where it is, and they can only enter the safe zone opened up in the ancient tomb city through the teleportation circle.

But now it was inadvertently discovered by Zhu Lingwu, I really don't know if it's providence or what.

"The Netherworld Mansion of the former General Zhennan, old ghost, what are you talking about!"

The little white fox naturally didn't know the secret, and couldn't help but ask Zhu Lingwu with some curiosity.

Zhu Lingwu roughly told the little white fox what he knew, "Speaking of which, the development and growth of the Xuanming Sect seems to have a lot to do with the ancient tomb city below, the ancestors of the Xuanming Sect used this side to capture and refine the Xuanming Spirit Ghosts, and snatched the territory of some surrounding sects, so that they could dominate the territory of the Xuanming Sect for a while!"

"Oh, but, I saw it over there just now, it seems that there are skeletons patrolling like people, and there are some ghost-like things, what is going on!"

The little white fox's eyes smashed for a moment, thinking about the scene he had just seen through the eyes of the demon slave's ass, but he couldn't help but say with some suspicion.

"It's been almost forty or fifty years since the Xuanming Sect was destroyed, and in the past, the Xuanming Sect would send disciples to this trial secret realm every ten years to try, in fact, it was also to prevent the rebirth of powerful wild ghosts in the secret realm here, and now maybe there are natural ghost generals or something like that, after all, the ghost aura and aura in this ancient tomb city are very strong!"

Although Zhu Lingwu couldn't see the scene in the ancient tomb city with his own eyes, he was able to analyze the possible changes inside.

If the Xuanming Sect still exists, even if such a change occurs in this trial secret realm, the Xuanming Sect will naturally be able to send a master whose strength is above the Jindan real person to come and clear it, but now that this trial secret realm has naturally developed for decades, it is difficult to say that there has been any change in it.

Thinking of this, Zhu Lingwu had a little more special thoughts in his heart......
