"What's wrong?"

Yelian and Bucktooth Zhen cautiously swam to the side of the Sky Wolf and asked, but they didn't dare to say it directly, but used their soul power to communicate.

"Someone has already taken the lead in this soul nest!"

There was a look of jealousy in the eyes of the heavenly wolf, Yelian and Luo Yazhen had no different pupils, and he couldn't see the scene in the distance, but he could see it clearly.

They had swam out of the underwater passage now, but since it was a sewer, the movement here did not alarm the people in front of them.

"Could it be that the Ghost Mound City Lord and the King of Wu are here?" Ye Lian said worriedly, but she didn't provide any news about the Soul Nest!

"No, it's an old guy who was locked up in the dungeon with you at the beginning, and I let them go when I was you, I thought this person was just an ordinary Netherworld, but I didn't expect it to be so powerful that I could come here alone. ”

Being able to escape from King Wu's men, it is obvious that the strength of this old man is far beyond the imagination of the wolf, and now he doesn't know whether the other party is friend or foe, so the wolf did not act rashly.

Some time after the old man left, the wolf swam out with Yelian and Bucktooth Zhen, and when they came out of the water, they were immediately stunned by the sight before them.

What kind of underground lair is this, it's a rare paradise.

This is an underground world like a karst cave, full of stone stalactites made of unknown objects, inlaid with glowing crystals, and some buried in the underground soil.

When the wolf dug it out, it turned out that some pure soul crystals were of many times purer quality than the ones he had obtained from Uchburg before.

In addition, there are many spirit plants growing on the ground, most of which are yin-attribute heavenly and earthly treasures, but the heavenly wolf has found a strange pit, and there is still a trace of yang-attribute aura in it.

Obviously, it was a trace of extreme yang bred in this place of extreme yin, and a thing of extreme yang that went against the sky grew up, which should have been poached by the old man in front.

"The passages of this underground world are intricate, obviously the old man is taking this path, let's change the route to avoid running into him, in case there is a conflict, it will not be good. Sky Wolf said.

"Hmm!"

Yelian and Bucktooth Jane, of course, look at the wolf horse.

While the Heavenly Wolf was cautiously moving forward with Yelian and Luo Yazhen, the men and horses led by Gong Jiu, Gao Mao and Sun Tu also slowly converged towards the underground world in the center, fortunately there were more of them, otherwise they would not be able to resist the giant shark souls guarding the passage.

And in the central region of the underground world, a man wearing coarse cloth clothes and bare feet was constantly moving forward in the old man, and some fifth-level souls that swooped out from time to time around him were smashed by him casually and grabbed the soul core.

Those souls below the fifth level did not dare to approach this old man who did not seem to be very tall, because even if they had low intelligence, they could sense the aura of danger from this old man's body.

However, the old man did not look down on those low-level souls, and his trip seemed to be very purposeful, obviously not the first time he had set foot in this place.

"Old brothers, after a hundred years, I, Haikun, are back again, this time I will definitely kill that soul king and avenge you, and then unscrew off that Zhai Xin's dog head and drink for you!"

As he walked, the old man kept stuffing the soul core into his mouth, chewing it as if he were eating jelly beans. But if anyone stood in front of him, the old man's face was full of tears.

Although only some yellow appeared on the bones of the three Sky Wolves, they could be regarded as stepping into the category of fifth-level ghost soldiers, but it was only the early stage, otherwise they would not be able to resist the souls of this underground world at all.

Now the souls they encountered were not just those cute little dolphins, but all kinds of fierce and vicious spirits. The reason why the spirits they encountered before were in the form of dolphins and giant sharks was probably related to the Huangquan Lake on the periphery.

The lowest souls here are all level four, and some even surpass level five, with a variety of attack methods and extraordinary combat power, and now the thunder balls and wind blades they spit out, the sky wolves can no longer ignore them.

Bang!

When they passed a corner, more than a dozen fifth-level souls rushed out, and Yelian was suddenly smashed out by several thunderballs, but fortunately, half of her bones had turned yellow along the way, otherwise her bones would have fallen apart at this moment.

"Protect the Night Lotus!" the Sky Wolf shouted at Bucktooth Jane.

With his shout, the wolf spirit rushed out of his brow and pounced on one of the spirits in one fell swoop, and the wolf pounced on the other like an angry wolf.

Of course, Yelian and Bucktooth Zhen will not sit still, and immediately join the battle group, and under the battle of their three skeleton creatures and wolf spirits, those powerful souls have been ambushed.

After packing up more than a dozen fifth-level soul cores, Sky Wolf immediately found a secret cave, let the wolf spirit guard the entrance of the cave, and then began to refine the soul core, and they also collected a lot of soul cores along the way, enough for them to cultivate for a period of time.

However, the wolf did not forget the wolf spirit, and built a hill in it, and the wolf spirit was naturally unkind and happily devoured it, and now it urgently needs to recover its strength.

"Brother Sky Wolf, I'm sorry, we're dragging you down, Ah Zhen and I will stay here, and we should be able to protect ourselves after refining these soul cores." Yelian said a little embarrassed.

In fact, she had wanted to bring it up for a long time, just because of the weakness of the two of them, which slowed down the trip of the Sky Wolf, otherwise the current Sky Wolf would probably have entered the center of the underground world.

"Why is the big man such a mother-in-law, we were just caught off guard just now, besides, if you don't want to abandon us, wait until you find the Divine Soul Pool and then come here to pick us up." Seeing that the Sky Wolf seemed to be quite worried, Luo Yazhen hurriedly said.

"Okay, I will leave the wolf spirit to protect you, it is in line with me, and I can rest assured that I will keep it by your side. Sky Wolf said with a smile.

The wolf spirit turned around and nodded at the wolf, indicating that he was willing to stay.

Yelian and Luo Yazhen saw the wolf spirit nodding, and they were immediately overjoyed, they had already seen the strength of this wolf spirit just now, as long as it was there, it was almost impossible for them to have any accidents.

After separating from the Night Lotus, the speed of the Heavenly Wolf was indeed several times faster, because he didn't need to be distracted to take care of others, under his elusive body, those low-level souls couldn't detect him at all, and only the fifth-order soul Heavenly Wolf would do it.

In the cave where he was separated from the Night Lotus, the Sky Wolf discovered one thing, only a fifth-level soul could allow him to advance, which seemed to involve the law of the ghost path, and the souls below the fifth level did not give birth to the power of the ghost path.

Therefore, the Heavenly Wolf hunted and devoured day and night, and then urged the Chaos Fire Fetus and the Chaos Origin Refining, and the Huang Yun on his body was also constantly spreading, and in just ten days, the soul power that the Heavenly Wolf used for himself was no less than the work of the ghosts in the outside world for decades.

Nearly half a month after the Heavenly Wolf left the Night Lotus, there was a sudden huge fluctuation in front of them, and the terrifying wind could be felt from afar.

"Oops, it must have been that old guy and the Soul King who did it!"

As he spoke, the wolf had already pounced like a nimble cheetah, shuttling between the endless stalactites, like a fluctuating yellow light, so fast that it was terrifying.

"Roaring ——"

When the wolf came to the center of the soul nest, he happened to hear an angry roar, and a huge humanoid black shadow smashed a thin figure away.

A stalactite pillar that could be ten zhang thick was pierced, and the old man vomited blood and slipped down from the second stalactite pillar with deep hatred and unwillingness in his eyes.

Feeling the terrifying aura of the Soul King, where does the Heavenly Wolf dare to delay, and let it continue to make trouble, the breath here will definitely leak, and when the time comes, he will already be dismantled by Zhai Xin and King Wu.

After the Heavenly Wolf sacrificed the array card in his hand, purple light flew out from the array card, wrapping around the giant-like soul king like a gauze cloth.

The Soul King urged all his soul power and constantly resisted those purple lights, but no matter how hard it struggled, it couldn't break free, and in the end it was tightly bound by the purple lights.

Feeling the sluggish aura on the Soul King's body, the Sky Wolf relieved his heart and looked at the old man who was struggling to get up.

"Are you alright, brother?" asked the wolf.

"I can't die yet, I didn't expect to be saved by your kid again, it's really enough to be a fool!" the old man vomited out a mouthful of blood after speaking.

"Brother, don't worry, this soul king won't be able to break free for a while, you can heal slowly. ”

After the wolf finished speaking, he began to walk towards the crater-like waterhole behind the Soul King, which was filled with viscous colorful liquid, and the dream-like color made the wolf's soul fire sway.

Obviously, this is the legendary Divine Soul Pool, compared to the rich soul power of this Divine Soul Pool, the one that the Heavenly Wolf encountered under the Soul Refining Cliff back then was simply a dull clear water.

"In Xia Haikun, I don't know what to call the little brother?" the old man asked, looking at the wolf.

"Sky Wolf!"

Hearing the name of the Heavenly Wolf, Hai Kun's eyes suddenly cracked: "But the descendants of the Heavenly Emperor of the Shenqi Continent?"

"I am also a person of that era, and the Emperor of Heaven is my idol. Haikun said seriously.

"The Heavenly Emperor is indeed my ancestor. The Celestial Wolf looked at the still struggling Soul King and said, "Can you tell me what's going on?"

After devouring some soul cores, Haikun's injuries gradually stabilized, and he moved to the side of the wolf.

"A hundred years ago, a few of our like-minded old brothers roamed in this netherworld, although not as colorful as the world of the living, but they were also very happy, and we never thought that there was a traitor among us, who betrayed us in exchange for the title of lord of a small remote city. ”

"Zhai Xin?" asked the Heavenly Wolf curiously.

"Yes, we know that he is not a reincarnation, but we did not hide his identity from him, but if it is not my race, his heart will be different, and we died several people that time. In the process of escaping, we strayed into this soul nest, thinking that we could take the opportunity to rise, and then find Na Zhai Xin to take revenge, but I never thought that there were souls of the god realm in this soul nest, and the brothers all died here in order to let me leave safely. ”

"No wonder, but do you know that if it weren't for my formation card, the news here would have leaked out, and then Zhai Xin would have personally found it. The wolf looked at Haikun, not knowing what the old guy thought.

"I naturally know this, if I can beat this soul king, it is the best, I devour his soul core, and it will naturally become stronger, and then I can find Na Zhai Xin for revenge, even if I can't beat it, I can let the breath here leak out, and lead that Zhai Xin to come over and send him to death. Haikun said helplessly.

The appearance of the wolf shattered his wishful thinking.

But this is not a bad thing, at least he survived, and there was still hope for revenge, and even if he died, Zhai Xin might not die here.
