The mountain of death can be said to have been caused by Yao Yue and Xiang Arrow Rain.

If Yao Yue hadn't been brought to Arrow Rain and wanted to frame Yao Yue, Yao Yue wouldn't have wanted to find out what was going on here, but in the end, it caused such a result!

Luckily, they escaped fast enough, otherwise they would have died in the cave!

Now, Yao Yue and Xiao Hei jumped down to the bottom of the cave, and there were no traps waiting for them, and there were no imperial corpses to stop the attack.

When they fell to the bottom of the cave, they happened to see a stone door lying open, where the death gas was the most intense and terrifying, any death breath was enough to kill any emperor!

Fortunately, they already had the ability to refine death qi, so they could withstand such an environment.

Xiao Hei was very happy with this environment, and he kept inhaling the dead air and pouring into his body, looking quite excited.

Yao Yue thought of the magic spell that Xiao Hei had cast on the emperor's corpse just now, it should be the spell that Xiao Hei had cast!

This spell can not only deprive others of their life force, but also subdue some evil things for their own use.

Xiao Hei's ability is not enough, otherwise those imperial corpses will be able to be bound by its underworld spell and control it for its use!

Yao Yue had to sigh in his heart, "With Xiao Hei by my side, it's really my blessing!"

Although Xiao Hei's strength is not as strong as Xiao Liuzi, what it has is incomparable to Xiao Liuzi.

At this time, Xiao Hei said to Yao Yue on the side, "Boss, there may be corpses inside, can't we get in?"

"What, and corpses?" Yao Yue exclaimed.

Then, he used his divine pupil to look inside, piercing through a rich dead aura, and saw a dense corpse inside.

In an instant, Yao Yuehan's hair stood on end.

It was the first time he had seen such a terrifying scene, could he not be frightened?

Besides, if these corpses were all imperial corpses, once dispatched, he would definitely die, and at the same time, it would be a disaster for the Holy Land!

He wanted to run away as soon as he wanted to, but in the end he just endured it and didn't escape.

"Maybe these corpses can't move like the other imperial corpses?" Yao Yue guessed in his heart.

Yao Yue sensed it again and again, and found that these corpses really didn't move, so he strengthened his courage and walked in with Xiao Hei.

However, Yao Yue had just taken two steps and immediately stopped, his eyes staring at the rock walls on the left and right sides, and faintly he seemed to see the formations floating.

"There is a Yuan Array here!" Yao Yue exclaimed in his heart, and immediately stopped Xiao Hei from moving forward, so as not to touch the changes in the Yuan Array, thus causing unnecessary danger!

Yao Yue carefully looked at the surrounding formations, and found that these formations were extremely mysterious, and they were definitely above the emperor level!

If it weren't for Yao Yue's master Lone Stream who taught the Ten Thousand Array Diagram and explained many formations to him, it would be really difficult for him to distinguish the arrangement of these formations!

"These formations are vigorously outlined, and they are extremely smooth, and they can't be reached by a non-grandmaster! Judging from the extension of the formations, this must be a big array, the dead qi here is strong, and the yin qi is extremely heavy, could it be a great array of gathering yin?" Yao Yue said clearly in his heart.

After he looked at it again and again, it was finally certain that this must be the Yin Gathering Great Array!

The Yin Gathering Great Array is a formation that gathers all kinds of Yin Qi and evil Qi, which is a very beneficial formation for people who cultivate Yin Qi, in other words, for those who have improper intentions and like to follow crooked ways, it is the best formation for creating evil things.

It can be distinguished from the corpses here, and this Yin Gathering Great Array is precisely to create all kinds of death and evil qi, so that the corpses are mutated, so that they can act like people.

Otherwise, how could those corpses of the emperors who had already died come out to attack others again.

Yao Yue suspected that in addition to the Yin Gathering Great Array, there were other evil formations here, so that the corpse could truly "live"!

"If you want to cultivate an imperial corpse, I don't know how many years it takes to accumulate and how much yin qi it takes, this formation is only afraid that it was laid down when the Void Heaven Palace was stored in the past, could it be that there were people in the Void Heaven Palace at that time who cultivated some kind of evil feats to drive away corpses?" Yao Yue thought in his heart.

Yao Yue shook his head, he didn't plan to think about it, since he knew that this was the Great Yin Gathering Array, as long as this Great Array was broken, it would definitely be able to completely disappear the environment here, and those dead qi would gradually disperse, and he couldn't endanger others.

But he didn't want to do that now, he had to go inside and find out before making a decision.

Otherwise, once the dead air here is gone, there will be no secrets here, and it will be impossible for him to gain anything by then.

Yao Yue stepped into it step by step, he was not worried about any more danger!

After all, the lifeless atmosphere here is already the biggest obstacle, even if the emperor can't get in, he doesn't worry that there will be an offensive formation inside, otherwise it will be a superfluous move.

Yao Yue looked at the immortal corpses all over the ground along the way, and he couldn't be calm at all!

Fortunately, he was quickly attracted by the imperial armor and weapons on these corpses.

"These imperial soldiers are not corroded, although they are stained with a large amount of dead qi, if they can purify these dead qi, they will definitely be able to restore their brilliance!" Yao Yue was more and more happy the more he thought about it, he planned to collect all the imperial armor and imperial guards on the corpses here.

Thinking of this, Yao Yue didn't say a word, so he ordered Xiao Hei to work with him and took off all the weapons on these corpses.

There are at least two or three hundred corpses here, and although not every corpse has a weapon, half of the corpses have this weapon, which is already a very big gain.

These imperial soldiers range from inferior to high-grade, and although they contain a lot of dead energy, once purified, they will definitely be able to be used by anyone.

When the time comes to put it up for auction, it will be a very terrifying fortune.

Yao Yue thought of this, and after putting away a large number of weapons, he left Xiao Hei with a high-grade imperial spear, while he himself used an evil sword.

This evil sword not only did not fail to exert its original power because of the death qi, it was originally a weapon of the Yuan Force of the Dark Realm, but it matched with these death qi, making this evil qi extremely rich and possessing the ability of a top-level imperial soldier.

The evil sword, with a tiger-shaped hilt and a slender sword body with teeth and teeth, gives people a sense of evil spirit.

Yao Yue used his Dark Realm Yuan Force to drive, and the majestic power burst out, and the strong death qi was enough to kill any emperor.

"Good sword! This evil sword is better without purification!" Yao Yue praised.

Immediately after, he continued to walk inside with Xiao Hei.

This underground secret room covers an extremely large area, and Yao Yue felt that he was heading towards the belly of the mountain little by little, and the dead air around him became more and more intense.

Yao Yue observed all the way, and he found that the formation patterns here continued to go deep inside, and his face became more and more solemn.

"Could it be that those corpses outside the face are just incidental, and the real highlight is in the depths?" Yao Yue thought.

If there is a more terrifying existence in it, then if he continues to walk, it will definitely be self-defeating!

Yao Yue didn't flinch, he had already come to this point, and it was absolutely impossible for him to have a reason to go back.

Yao Yue stiffened his head and continued to move forward with Xiao Hei.

The death qi became more and more intense, and each dead qi was enough to kill any emperor in an instant, which was really terrifying.

Little Black is getting happier and happier, greedily sucking in the dead air here, and its strength is growing at a rapid rate.

Yao Yue was barely able to absorb some of it, but his body was a little unbearable, and he looked a little older, he was worried that if he continued, he would not be able to absorb the dead qi here, and would die directly here.

Fortunately, Xiao Hei was on the side, and from time to time he used white horns to inject some vitality into him, so that Yao Yue's impact was minimized!

Yao Yue's Fire God pupils kept beating, but unfortunately the visibility was getting shorter and shorter, and he couldn't see what was in the depths at all.

However, he suddenly saw black herbs growing on the rock wall, surrounded by a dark dead air.

In this desperate place, what can still grow must not be mortal!

Yao Yue stepped forward to take a closer look, and immediately exclaimed, "This, this is the Hell Grass, also known as the Hell Grass, it is said that there are evil herbs growing in the Hell, this is a medicine king-level herb!"

As soon as Yao Yue's words fell, Xiao Hei immediately couldn't wait to step forward and bite off one of the Stygian Grasses!

This herb is the herb that the demon horse likes to devour the most!

When Xiao Hei had just swallowed a Stygian Grass, it immediately roared, and its strength instantly surged, and the power of the demon core kept flickering.

"This is the King of Medicine! Xiao Hei is only afraid that he will continue to improve! What a good opportunity!" Yao Yue said happily for Xiao Hei.

For anyone, taking a bite of the underdog is certain to die, but it is a great supplement for Xiao Hei!

Perhaps the Stygian Grass also has an unexpected effect for some people who specialize in the special exercises of the Dark Realm Yuan Force.

Yao Yue didn't think about it, and put away all the dark grass here.

Anyway, these are the king of medicine, which is useless to him, but they have a great effect on Xiao Hei, so naturally he can't let it go.

After Yao Yue finished doing this, he looked at Xiao Hei on the side and found that it was refining the Stygian Grass at full speed, and it was impossible for him to wake up for a while, so he continued to walk alone.

It didn't take long for Yao Yue to find that there was a formation in front of him blocking his way.

This is not an offensive formation, but an advanced psychedelic formation.

This psychedelic array made Yao Yue see the entrances of eight passages, each of which had terrifying evil demon beasts blocking his way.

At first, he was so startled that he almost turned around and ran away.

Fortunately, his Nether Eye played a role, and when he found that these were just shapes condensed by death qi, not real beings, he calmed down, and then transformed into the Fire God Pupil, distinguishing that this was a high-level psychedelic array!

This psychedelic array is much more clever than the one he has laid down, and if the emperor comes here, he will be confused.
