Seeing that Blaze was so worried, Yan Fei smiled faintly, he did want to continue to try to fuse, but now that his strength had reached the peak of the three-star battle saint, now that he was controlling the Ten Thousand Skull Necklace, his forward speed should not be too slow. Thinking like this, Yan Fei did not hesitate and quickly controlled the Ten Thousand Skull Necklace.

The next moment, Yan Fei only felt that the necklace of ten thousand skeletons that was originally shuttling in the sky suddenly lost its trace, and it arrived almost instantaneously between the two points, and this speed was a world of difference compared to before.

Huang Fuxuan and the others, who were in another space, naturally didn't know what was going on in the outside world, but when they recalled the vibration that had happened in the Ten Thousand Skulls necklace just now, everyone's expressions looked puzzled.

"Hmph, let him control it slowly, when he can't get the Heavenly Immortal Mountain, the Underworld Lord has already fully recovered, and he is still talking about a fart assassination!" Yan Qing said a few words with a gloomy face, and he still had a problem with Yan Fei in his heart.

Yan Chi on the side could only sigh secretly when he heard this, and muttered in his heart: "The fifth child still has this temper, after so many years, can't this guy change it?" I think that Ah Fei's kid is much stronger than those juniors in the clan, although his strength is a little weaker, but he is impeccable in other aspects. ”

At this time, Yan Chi secretly made up his mind that if Yan Fei had the ability to participate in the Yan clan patriarch competition in the future, then he would have to help, and Yan Fei already had the chain of patriarch token devouring, as long as he could support this kid to take the position, then he could put many things on the surface.

In the blink of an eye, half a day passed, and just when everyone was bored, Yan Fei's figure appeared in front of everyone.

Yan Qing still had the same unhappy expression when she looked at Yan Fei, and when she saw Yan Fei's arrival, she turned her head away and didn't look at Yan Fei at all. Yan Fei didn't pay attention to Yan Qing's attitude, he didn't need others to prove his existence, he would use his own actions to prove his value and the meaning of his existence.

"Teacher, we have arrived at Tianyin Mountain, but there seem to be a lot of demon powerhouses here, and the kid didn't dare to take action. ”

Yan Fei looked at Huangfu Xuan and said calmly, when he said this, several people on the side suddenly fell into shock, how long has it been? It has already reached Tianying Mountain? Didn't it mean that it would take at least a day?

Huangfu Xuan nodded with satisfaction, he knew that Yan Fei was an unwilling person, and he would only use his actual actions to calm down his unwillingness.

"Wouldn't it be? It's been a day so soon, you kid better not be mistaken, you know how important this operation is to us. Yan Qing didn't turn her head to look at Yan Fei, and said with an unkind expression.

Yan Fei didn't care at all about Yan Qing's threat, and lightly touched his hands in front of him a few times, and then, a perspective appeared in everyone's eyes out of thin air.

In front of him is a big mountain that goes straight into the sky, the dense air is filled with a depressive breath, the whole mountain is majestic and mysterious, it looks like there is a feeling of covering the eyes, at the same time, a stream of light and shadow is constantly flying back and forth in the air, the weakest strength of these people is the peak Demon Venerable, it looks like they are on guard patrol.

Seeing this scene, everyone finally believed that they had really arrived at Tianming Mountain, and Yan Qing, who had always been obsessed with Yan Fei, bit her lips tightly, looking sullen.

"Looking at the appearance of these guys, the Hades Lord should not have broken free from the backlash of the Heavenly Netherfire, we have to hurry!"

Wei Chi stared at the light and shadow in the perspective and said urgently.

"Well, since the Heavenly Immortal Mountain has arrived, we should just kill it. Although there are a lot of demonic cultivators out there, it is not enough to stop us with the abilities of these guys. ”

Bing'an said coldly, those demon cultivators who were patrolling back and forth in the outside world, although the lowest strength was the peak Demon Venerable, and the highest point also had two or three star Demon Saints, but this kind of strength was not taken into account by these high-level War Saints. Their group, Yan Chi and the other five Yan Clan Yan Jun, their strength is around the Seven Star War Saints, and An Cang, Shui Yun, Bing'an, Phantom Song and Wei Chi are also about the same, as for the most mysterious and powerful Huangfu Xuan, their strength may at least have the ** Star Saint level, such a strength is enough to sweep away those demon cultivators outside in minutes.

"No, do you think that the place of retreat of the Underworld Lord is so powerful? I think these demon cultivators outside are probably just decorations, and the real hidden strength of the Black Demon Clan is afraid that it will not be easily discovered. At the moment, the best way for us is to find the specific location of the Underworld, and it is not too late to do it at that time. ”

An Cang rejected Bing'an's mention in one bite, he had seen a lot of the practice of hiding the strength of various races, just take the previous incident of the War Dragon Clan, who knew that there were still strong people like the War Dragon Ancestor in the War Dragon Clan, judging by the news brought back by Lei Sheng and others, the strength of the War Dragon Ancestor was at least the peak six-star Battle Saint strength, and maybe it had broken through the seven-star Seven-Star Clan. The War Dragon Clan alone is so deeply hidden, so as one of the most powerful forces in the Demon Clan, how can the hidden power of the Black Demon Clan be small?

Speaking of this, An Cang looked at Yan Fei, "Little junior brother, I'm afraid I'll have to trouble you about finding the Hades Lord next, after finding the Hades Lord, we will kill it, I believe that our success rate should be not small if we are caught off guard." Teacher, what do you think is good?"

After speaking, An Cang set his eyes on Huangfu Xuan, as if he had the intention of asking.

Huangfu Xuan nodded lightly, looked at Yan Fei and said, "Just do what your senior brother said!"

After hearing such an arrangement, Yan Fei flew away, the Heavenly Immortal Mountain said that it was not big, and it was definitely not small to say that it was small, it was not a simple matter to let him find the location of the Immortal Lord in this vast mountain, but at this time, in the Ten Thousand Skull Necklace, there was still the Demon Ancestor of the Demon Saint, with its relationship with the Black Demon Clan, he must know where the Immortal Lord was in the Heavenly Immortal Mountain.

As soon as Yan Fei's figure flashed out, the Ice Shadow Ancestral Fire and other strange fires rushed straight over, and the Hell Refining Fire and Bloodthirsty Flame at this moment all looked a little sluggish, and after nearly half a day of integration, they were also slightly tired.

"Ah Fei, how did you do it? Looking at you like this, it doesn't seem to have the negative effect mentioned in the Alien Fire Fusion Decision?" Bing Youzu Huo looked at Yan Fei up and down, today he saw many miracles in Yan Fei's body, this guy didn't have anything to do after withdrawing from the fusion, but he was tired enough of the two different fires of Bloodthirsty Flame and Hell Refining Fire!

Yan Fei waved his hand at the Ice Ancestral Fire, if he knew what was going on, he wouldn't have fiddled with such an innocent look. Then Yan Fei came to the space where the Troll Ancestor was, and the Troll Ancestor sat on the ground at this time, and after feeling the breath of Yan Fei's arrival, he opened his eyes slightly, and then closed his eyes again as if he hadn't seen Yan Fei.

"Troll senior!" Yan Fei shouted softly at the Troll Ancestor.

"Just say anything, if you get to the Heavenly Underworld Mountain, let me out quickly, I can't get used to this place!" said the Troll Ancestor indifferently, his eyes always closed.

"The Heavenly Immortal Mountain has indeed arrived, but where is the Immortal Lord in the Heavenly Immortal Mountain? Please also ask the troll seniors to inform one or two, after this incident, the kid will definitely let the seniors go as soon as possible. Yan Fei looked at the still calm Troll Ancestor and said.

Hearing Yan Fei's words, the Troll Ancestor slowly opened his eyes, "Have you all arrived at the Heavenly Immortal Mountain?" In this case, you go directly to the mountain on the west side of the Heavenly Immortal Mountain, probably in the middle of the mountain, there is a cave mansion, and the Immortal Lord is in it. Boy, I've said everything I need to say, can you let me go now?"

The Troll Ancestor stared at Yan Fei, this time for the sake of the Troll Clan, he betrayed the Dark Demon Clan's Hades Lord, if he let the Hades Lord know that he had sentenced him to leave him, then the consequences would be severe.

Yan Fei hesitated slightly, if he let the Troll Ancestor leave now, not to mention that as soon as his figure appeared, it would attract the attention of those patrolling demon cultivators in the outside world, and besides, it was not certain whether what the Troll Ancestor said to him was true or not, in case this guy yelled and shouted about their existence as soon as he went out, wouldn't this be lifting a stone and shooting himself in the foot?

Perhaps seeing that Yan Fei was worried, the Troll Ancestor snorted coldly, and continued: "If you are worried about me reporting the news, then let me out when you leave." Of course, before this, you can't reveal my existence to any demons, let alone let the Lord of the Underworld know that I sued you that he was there, if you can do this, then go on your own!"

Saying that, the Troll Ancestor waved his hand at Yan Fei, it seemed that he seemed calm at this time, but in fact, his heart was full of anxiety and guilt, and even he didn't know whether it was right or wrong to do this.

Yan Fei stared at the Troll Ancestor, then turned around and left, since the Troll Ancestor had said so, he naturally didn't know what to say, and besides, he wouldn't let go of the Troll Ancestor because of this.

At that moment, Yan Fei came to the location of Huangfu Xuan and the others, and slowly shuttled towards the west of Tianming Mountain with the Ten Thousand Skull Necklace, since he had arrived at Tianying Mountain at this time, he didn't have to worry about controlling the speed of the flight of the Ten Thousand Skull Necklace.

But the more he moved forward, the more doubts Yan Fei's heart became, as he continued to move forward, there were fewer and fewer demon cultivators on patrol, until when he finally arrived at the place that the Troll Ancestor said, there was not a single demon cultivator in sight from the outside world.

"The Troll Ancestor won't fool me, right?" Yan Fei's heart trembled, and his expression became a little uneasy.

At this time, the Ten Thousand Skull Necklace was floating in front of the door of a black hole, and Yan Fei did not recklessly fly into it with the Ten Thousand Skull Necklace, because he didn't know what dangers would exist in this dark-looking cave.

"Ah Fei, the Troll Ancestor didn't lie to you, the Lord of the Underworld is in this cave, and there are many masters in the cave, all of them are high-level demon saints. Just when Yan Fei was puzzled, Huangfu Xuan said lightly, and as he said this, An Cang showed a slightly shocked face.

"This underworld lord is smart, but the place where he is heavily guarded on the surface is not his real retreat, but the place where his real body is located, there is not even a caretaker, this trick is indeed enough essence to hide people's ears, but what he didn't expect was that the troll ancestor would betray him, this can be regarded as his fate!"

An Cang smiled indifferently, since he had found the location of the Hades Lord, the next thing became a lot simpler and rude.

"Ah Fei, wait a minute and control the Ten Thousand Skull Necklace into the cave, if it is not discovered, it will be fine, you will directly take us to get as close to the Hades as possible at that time, and when the time is ripe, with the strength of many of us, we will definitely be able to give the Hades Lord a fatal blow." If we are discovered, we will be released directly, and it will depend on our ability to succeed or fail at that time. Huangfu Xuan stared at Yan Fei and ordered, at this time, before coming to this cave mansion, he already had a faint feeling of being noticed, so he hurriedly ordered the matter to continue, even if it was exposed, everyone would not be confused because of this.

At this moment, everyone's nerves were tense, and Yan Fei was fully controlling the Ten Thousand Skull Necklace to sneak into the cave.

As soon as he entered the cave, Yan Fei only felt that his vision was blurry, and he couldn't see anything at all, but as he continued to go deeper, the distance became brighter and brighter, and what made Yan Fei's heart tremble even more was that this way, almost every other distance, there was a demon cultivator sitting with his eyes closed, looking at his expression and checking his breath, it was definitely not comparable to those cats and dogs outside, these guys turned out to be all high-level demon saint powerhouses, that is to say, the dozen or so people he met along the way actually had the strength of a five-star demon saint at least.

Looking at this scene in the outside world, An Cang and the others' expressions also became solemn, and it was only at this time that they spied a little bit of the hidden strength of the Black Demon Clan, and they all admired the strength of this race in their hearts.

After passing through the long corridor, an incomparably spacious hall appeared in Yan Fei's eyes. It was a square platform in the shape of a gossip, and at this time, there were eight people sitting on the ground around the platform, and a stream of extremely powerful demonic energy continued to fly out from the hands of these eight people, shooting straight to the center of the high platform. There, at this time, it was covered with a dark light, and when you looked at it faintly, it seemed that you could still see a figure inside.

"Heavenly Darkness!"

"Hades!"

In an instant, An Cang and Yan Chi in the Ten Thousand Skull Necklace shouted out without their own voices. Yan Fei gave Huang Fu Xuan an inquiring look, because at this time they had already discovered the location of the Hades Lord and the Heavenly Netherworld Flame, as long as Huang Fu Xuan nodded, Yan Fei would move everyone out as soon as possible, and when the time came, he would definitely be able to give these demon cultivators a big surprise.

"Don't worry, try to get closer to the dark light, if we can get closer to the Underworld, then the chances of success will be greater. Huang Fu Xuan calmly commanded, from the moment he entered this cave mansion, he had thought about it, with the strength of the nearly twenty high-level demon saints outside, if they couldn't succeed in one blow, then it would not be easy to attack the underworld lord again.

Yan Fei nodded, and continued to control the Ten Thousand Skull Necklace fluttering, at this time Yan Fei was extremely careful, to say that when he rushed to Tianying Mountain before, he needed the Ten Thousand Skull Necklace to burst out at an extremely fast speed, then at this moment compared to before, it was another extreme, Yan Fei was afraid that because of his own mistakes, some unimaginable consequences would happen.

Gradually, the Ten Thousand Skull Necklace had floated to the high platform, and through the perspective transmitted from the outside world, Yan Fei could even clearly see the eight demon cultivators sitting around outside.

"Four Black Devil Elders?" Yan Chi muttered softly, and there seemed to be a few people among the demon cultivators outside that he knew.

"Go on!" Seeing that Yan Fei seemed to slow down his movements, Huang Fuxuan whispered.

When Yan Fei heard this, he could only continue to control the Ten Thousand Skull Necklace to move forward, and after a while, the Ten Thousand Skull Necklace had already flown to the inside of the high platform, compared to the eight demon cultivators around the high platform, its position at this time could already be regarded as the inside of the high platform. And not far away, is the Lord of the Underworld who is wrapped in the fire of the Heavenly Netherworld.

Huangfu Xuan made a stop gesture towards Yan Fei, and then nodded fiercely at Yan Fei, An Cang and the others on the side were also ready to go, but there was a somewhat nervous look on their cheeks, although they were all high-level battle saint powerhouses, but they were so deep in the Demon Domain, facing so many high-level demon cultivators, it was inevitable that they would be a little uneasy.

After receiving the signal from Huang Fu Xuan, Yan Fei's mind moved suddenly, and then directly moved Huang Fu Xuan and the others out of the Ten Thousand Skull Necklace.

At this moment, the eight demon cultivators on the high platform suddenly opened their eyes, and based on his perception, they had already noticed it when An Cang and the others first appeared. Huangfu Xuan pointed at the air, and the aura of his whole body exploded without concealment, and then shot straight towards the dark light, while Yan Chi and the other five Yan Jun and An Cang and the others rushed towards the eight demon cultivators from the inside out.

The battle took place almost in the light of lightning, and a powerful aura rippled out of the cave.

"Hades Lord!" The black-robed old man shouted, only to see that as he fell, Huang Fu Xuan's fingers had already penetrated into the dark light cluster, and in an instant, an earth-shattering sonic boom exploded directly from the light cluster. For a while, the mountain shook, the gravel flew sideways, and the entire Tianying Mountain shook at this moment.

The figure in the dark light group shattered into countless fragments under Huangfu Xuan's blow, but the dark light group was broken into countless small light clusters and then reunited together.

Majestic battle qi and demonic qi disturbed, and then, on the top of the Heavenly Underworld Mountain, a pillar of light flew straight out, accompanied by countless mountains and rocks. The next moment, one after another light and shadow rose into the sky, An Cang and the others saw that Huang Fu Xuan had succeeded in one blow, and they did not entangle with the masters of the Black Demon Clan, they all returned to Huang Fu Xuan's side, and then formed a circular battle circle.
