Such a large ancient tomb can be hidden under the mountains and not be known, which is really a big deal.

In this way, the ancient tomb below may still be a very old ruin, and the mountain above may have been originally the sealed soil of the cemetery, or it was deliberately moved to cover the ancient tomb by means of magic.

"Well, the place where the ass went in, it's not the right way to the ancient tomb, it's too big down there, the ass can't even find it, it seems to be in a certain block of the ancient tomb now, if we want to think about this area, I'm afraid it will take a lot of effort, the ass seems to have found a small crack to get in! Strangely, there's something that's interfering with my connection to my ass, so I can't see it clearly. ”

The little white fox could have been in contact with the demon spirit slave and saw everything the butt saw, but now it can only see hazy.

"Huge city, skeleton puppets, ghost generals, etc., I seem to know what kind of place this is! It seems to have something to do with the Xuanming Sect!"

Zhu Lingwu listened to the little white fox's relay, and several messages suddenly flashed in his mind, all of which were memories left by the Nameng pharmacist, and these memories seemed to be somewhat consistent with the little white fox's description.

"Oh no, the ass was discovered, and I let it escape!"

The little white fox's tone changed suddenly, and it seemed that the demon spirit slave fart was still detected in the ancient tomb.

"Well, let it come back! I know what kind of place this is, this is the underground mansion of the former general Zhennan! Actually, it is also a place of trial of the Xuanming Sect, I can't imagine that it is here, originally the Xuanming Sect was sent to the bottom through the teleportation array, and I don't know the true location of this underground mansion, but it turned out to be here!"

After Zhu Lingwu read the memory information of the Mongolian pharmacist, he knew what the following place was.

Zhu Lingwu really didn't expect that there was such a coincidence in the world, he casually found a place for the five Xuanming ghost heads to practice the Five Elements Escape Technique, but he was able to find a secret realm of trials of the Xuanming Sect.

The so-called Trial Secret Realm is mostly a special area for some large-scale extra-worldly sects, in order to assess the cultivation progress of the disciples in the sect and increase their actual combat ability.

This kind of trial secret realm is generally also many ancient ruins, or in some primitive mountains that have been encircled, these places have actually been explored by the masters of the world's outer sects, and some dangerous and safe different areas have also been circled.

Therefore, the disciples of the Outer World Sect can enter different regions to test according to the strength of their respective strengths, and naturally they can encounter dangers relative to their strength, thus forcing out their hidden combat strength.

Of course, these trial secret realms also have a lot of materials, materials, and so on that can be collected and collected, and the disciples of the worldly sects participating in this kind of trial task naturally have the requirements to collect and collect.

Of course, the sect also allows them to find some things in these trial secret realms on the premise of completing the task as their personal belongings to improve their strength.

It can be said that the Trial Secret Realm is also a resource production place for a sect outside the world, and the trial actions of those sect disciples are also a kind of material collection work.

Therefore, this kind of trial secret realm will also be hidden by the predecessors of the worldly sects with special means, so as not to be discovered by other sects and sneak in to plunder the materials inside.

However, different worldly sects have different requirements for the trial secret realm, and many worldly sects will set the trial secret realm in the primordial mountains, the main purpose is to collect the primordial growth of the elixir inside, and they will also let the disciples slaughter some wild free-range low-level demon beasts, and collect the things on these demon beasts as various materials, so that it is somewhat like a wildlife park in modern society.

And the Xuanyuan Sect is an evil sect that plays with ghosts and souls, and the things they need are naturally some ghosts, underworld things, and the like.

The ancient tomb under the mountain range where Zhu Lingwu is now located is the huge ancient tomb of a Zhennan general in the Han Dynasty before the Great Jin Dynasty.

This former general Zhennan is also a child of the royal family of the previous dynasty, and according to legend, he is also a Jindan real-life master, but Jindan Zhenren is not an immortal immortal after all, so as his longevity came to an end, in order to continue his life, he began to go crazy.

It's a pity that Shou Yuan Tianding, he can't stop his physical body from aging no matter what, and after he failed to break through the Yuan Ying realm several times, he can only turn to other ways to continue his life.

In the end, he fell into the devil's way, and secretly colluded with the demon gate as the general of Zhennan of the Han Dynasty, it can be said that in the process of the fall of the Han Dynasty, the former general Zhennan also became one of the important driving forces that promoted the historical process and triggered the outbreak of the demon catastrophe in the last years of the Han Dynasty.

Later, the demon catastrophe broke out, and the general of Zhennan cut off the land and became a local emperor in the troubled times.

But his body was still aging rapidly, and he couldn't preserve it anymore, so he secretly built a netherworld mansion for himself.

He was going to turn to the ghost path and wanted to make himself a ghost king, so he used all his power to build an underground tomb city like the Nether King City.

And after the completion of this tomb city, he killed all the craftsmen and servants who built the tomb city, and also moved the households of several cities in his territory, enough to millions of people, all killed in the tomb city.

In addition, there are 200,000 Zhennan legions under his command, and all the descendants of his descendants were also killed alive in the underground tomb city.

It can be said that this Zhennan general killed millions of people in a frenzy at that time, just to add enough ghost people to his Netherworld Kingdom, and also to form a powerful ghost country army.

He wants to bring all the power of his life to his own grave and become a true ghost king.

This incident also became a legendary event that caused a sensation in the entire Xuanyu Continent at that time, the Zhennan general disappeared out of thin air with the populations of several surrounding cities, and the disappearance of millions of people made the Zhennan general's territory a vast and sparsely populated terrifying place.

And although this Zhennan general's actions are crazy, he is not stupid, he understands that if he does such a thing openly, it is likely to attract the interference of others.

Although Xuanyuzhou was already under the dark rule of the Demon Gate at that time, General Zhennan did such a thing, and it was also covered up by the background of the entire turmoil of the Dark Demon Tribulation.

But whether it is a powerful shili among mortals, or a cultivator sect in the immortal and demon cultivation realms, if he knew that he was going to drum up such a netherworld, he would definitely come to intervene, and might even directly refine him into a demon sect and ghost servant.

Therefore, during the construction of the ancient tomb city, this general of Zhennan not only used countless prohibitions to hide this ancient tomb city, but also deliberately built this huge underground tomb city under the mountain where Zhu Lingwu is now......
