I don't know how long it took, deep underground, somewhere inside the belly of the main peak of the Black Zombie Mountain, Yin Ning, who was almost displaced by the strong wind brought up by the violent black hurricane just now, finally woke up slowly.

Yin Ning was very alert, he had just regained consciousness, and he remembered what he had encountered before he fainted, and immediately tried to get in touch with his Shadow War Ghoul Scar, and issued an order to let the Ghost Scar protect him, and then released Devil May Cry, and took out the "Wave Scale Shield", held it in the palm of his hand, injected mana, and was ready to be activated at any time.

After making a defense that he thought was perfect, and successfully getting in touch with Devil May Cry, Yin Ning struggled to get up and began to observe his surroundings, to Yin Ning's surprise, the Shadow War Ghoul Devil May Cry and Xuxun, who fell into the big hole with him, were actually not far from him, Devil May Cry was coming after receiving his order, and it seemed that he had just woken up, and he also struggled to get up, and then observed the surrounding environment with a blank face.

Yin Ning found himself in a huge hall, this hall was very eerie, although the surrounding walls and ceilings were inlaid with countless unknown jade stones that could shine, illuminating the entire hall as if it were day.

But it also reflects the murals on the four walls and the ceiling very clearly, the murals are carved with many hideous ghost patterns, and there are many monsters that Yin Ning does not recognize, but at a glance he knows that they are extremely fierce and brutal, and there are many monsters that look like humans, but they either have long horns on their heads, or have several wings on their backs, or have scales all over their bodies and drag monsters that resemble snakes and lizards.

The reliefs of these monsters are the most lifelike, they are high in all the murals, as if they are the masters of all things, looking at those monsters, Yin Ning can't help but feel a sense of disgust for no reason at the same time, it is also an instant surge of fear, which makes Yin Ning's body tremble involuntarily.

Those monster reliefs made Yin Ning palpitate, but what frightened Yin Ning the most was not these, but the large number of coffins that were stacked almost all over the entire hall, and there were simply too many to count, a large number of coffins made of wooden stone or black metal.

As a disciple of the Corpse Nightmare Sect, Yin Ning has been dealing with corpses for many years, and it stands to reason that he will not be afraid of the coffins that hold the corpses, but the coffins in this hall are completely different from the ones Yin Ning saw in the Corpse Nightmare Sect, not only are there many of them, but these coffins all emit a very dark and cold aura, which is similar to the feeling that those monster reliefs bring to Yin Ning, or even deeper, extremely disgusting and terrifying at the same time.

Yin Ning was in this hall full of coffins, just like being in a snake cave full of poisonous snakes, and he was uncomfortable, Yin Ning always felt that at some point, among the coffins that seemed to have been stored here for a long time, one of them would suddenly open, and a ghost and beast depicted on the murals would pop out, or those unknown monsters would come out, leaving Yin Ning dead without a place to be buried.

"It's like a place where corpses are made. ”

Just when Yin Ning was about to suggest to Yu Xun to leave this hall to find a way out because of the creep in his heart, Yu Xun, who had been observing for a long time, suddenly spoke up and said to Yin Ning first.

"The place where corpses are made? This Black Zombie Mountain was originally called Tian'er Mountain, and it has always been a place for intermediate corpses, and it has always been a place for imprisoning zombies, and I have never heard of the sect transforming this place into a place for making corpses like the Valley of Raising Corpses, and the several sects that occupied this Tibetan Cuo Mountain Range before the Corpse Nightmare Sect were not known for their alchemy, and it was impossible for them to build such a large place for making corpses. ”

After listening to Yu Xun's words, Yin Ning was very shocked, temporarily put the fear in his heart behind, carefully observed the surrounding environment, and combined with some information and knowledge about the history of Black Zombie Mountain and the Corpse Nightmare Sect before coming to Black Zombie Mountain, he couldn't help but question it.

"I am the son of a corpse slave, I grew up in the valley of raising corpses, I have seen the process of making corpses countless times, it is impossible to be wrong, this place is a place of corpses, you see that it is the inscription table, it is the inscription of runes on those dead corpses, and that is the medicine pool, which is used to soak the dead corpses to enhance the strength of the corpses......"

Xun Xun, who has always been calm and has never been angry, is rarely a little angry this time, his voice became very loud, pointing to several places in the main hall, and said to Yin Ning.

"Then it's strange, why is there such a large corpse making place here, what the hell is going on?"

After listening to Yu Xun's explanation, Yin Ning also had a general understanding of the corpse-making process, and also knew that Yu Xun's judgment was correct, this vast and mysterious hall was indeed a place for corpse-making, but then a bigger question filled his heart, which made Yin Ning can't help but be surprised.

In this regard, Xu Xun could only shake his head blankly, but with a solemn face, a trace of horror flashed in his eyes and said to Yin Ning: " I don't know who this place originally belonged to, but I can be sure that according to the scale of this corpse-making place, it can refine more than 100,000 dead corpses at a time, which is more than 1,000 times the number of corpses made at one time in the current Corpse Raising Valley, even if these 100,000 dead corpses are made with the refining power of the current Corpse Nightmare Sect, only 30% of them have become walking corpses, and then with the current 10% acceptance rate of the Corpse Nightmare Sect, 3,000 awakened walking corpses can also be subdued as refining corpses, 3,000 corpses at a time, it is really unimaginable, how can the people who originally owned this place find so many dead corpses that are haunted by a large amount of curse and resentment and suitable for refining, and how did they find so many monks to accept so many corpses? ”

After listening to Yu Xun's speculation, Yin Ning's eyes began to flicker non-stop, and he said in a deep voice: "In other words, this hall is completely a place to make corpse refining legions, and it is likely to belong to a corpse refining sect that has not been recorded in the history of cultivation in ancient times or even in the primeval period. ”

"If that's the case, then the alchemy of this unknown corpse refining sect is many times higher than the current corpse nightmare sect, this corpse-making place is not only large-scale, but also its corpse-making techniques are more than the current corpse nightmare sect I don't know how many times, those corpse-making artifacts and facilities left here, only one percent is what I recognize, and I can say that it has a function, and two percent I can speculate and guess its function, and the remaining seventy percent is something I don't recognize at all, I feel that the corpse-making technique of the corpse nightmare sect seems to have been learned here, but it is very incomplete, it is the kind that you don't know, and the kind of corpse refining that you said existed in ancient times or even in ancient times, may really exist, and this corpse hall is the vestige it left behind. Yu Xunyou observed the surroundings and nodded heavily, indicating that he agreed with Yin Ning's speculation.

"This is nothing, the ancient primeval period was the glorious time of the cultivation civilization, and now many sects in the cultivation world are inherited from those great sects of the ancient primeval period, and the alchemy of the corpse nightmare sect is so numerous and complex, and it is definitely not created by a certain amazing and glamorous monk, it must also be inherited from a previous corpse refining sect, but it seems that after hundreds of millions of years, many inheritances are many missing, or because some elixirs are extinct and spiritual materials disappear, so the current corpse nightmare sect corpse making technique will be simpler than here, resulting in the situation that the current people are not as good as their predecessors。 Yin Ning's eyes flowed again, and he told his conjecture to Yu Xun again, and then after carefully observing the surroundings for a long time, he frowned and said: "This place is a little tidy, and there is no dust and dust, it seems that someone has been here a long time ago, it should be the people of the Corpse Nightmare Sect, or those zombies in the Black Zombie Mountain." ”

"It's already excellent that you and I don't die, do you still want to get some benefits? Now what matters is how we get out, and since someone has come, there must be a way to get in and out of here. After Yu Xun successfully teased Yin Ning this time, his face immediately became calm again, and he looked around with sharp eyes, looking for a way out.

"There is no way, we can only look for it ourselves, but we can't separate, the flying shadow corpse we chased just now was not absorbed like us, but jumped into the big hole by itself, indicating that this place is now likely to be occupied by a group of zombies, in this may be the place where the zombies are nesting, we must not separate, we will choose this direction to go all the way, if there is really no way out, then go back and choose a new way, with this stupid method, although it will be quite time-consuming, but it will be relatively safer. Yin Ning pointed to the north of the hall and suggested to Yu Xun.

For Yin Ning's cautious proposal, Yu Xun had no objection, and after releasing his Tianyan corpse, he walked towards the north of the main hall with Yin Ning.
