"Sister Mu, let's follow, this bone spear is so weird, maybe there will be some unexpected gains" Xia Mu looked at the bone spear that was about to disappear on the other side of the stone hall, and rushed over as soon as his body moved.

"Good. The green vine battle armor on the surface of Mu Qingxian's body emitted a burst of hazy blue light to protect his body, and then with a graceful flick of his body, he followed closely behind Xia Mu and entered the cave behind the stone hall.

The cave was extremely dark, and only the whirring wind and the faint howl of ghosts and wolves could be heard from the depths, and it seemed that there were still a lot of corpses and ghosts hidden inside, which made Xia Mu and the others feel more and more cautious.

"It doesn't look like it's going to be too safe here. ”

After Xia Mu whispered to himself, with a wave of his palm, a red flame flew out, levitating in front of the two of them, instantly illuminating everything around him.

Then the two of them followed the bone spear non-stop, and walked along the cave passage for several miles, before their eyes suddenly lit up again, and an exit appeared in front of them, and a faint green light came out of it.

Xia Mu and Mu Qingxian glanced at each other in surprise, and the vigilance in their hearts instantly increased a few points, and then the two of them flashed and walked out of the cave passage.

What appeared in front of the two of them was a stalactite cave with a diameter of more than 100 zhang, and a fist-sized green crystal hung on the top of the cave, and the green light that radiated from the outside of the stone cave was emitted from this green crystal.

And directly below the green crystal, the head of a strange creature that looked like a human and not a human, like a beast and not a beast, was chained there.

The head was full of white hair, the eyes were slightly closed, and the ears could not be seen, but there was a wolf's mouth under the human nose, and although it seemed to be dead at the moment, the flesh was not decaying, and there was blood dripping from it.

Such a strange situation, not to mention Mu Qingxian, even Xia Mu was shocked when he couldn't catch it off guard.

And the bone spear, right now, was sticking next to the skull, and it let out a wail.

"This head must be the owner of the bone spear, but it looks very weird, so many years have passed, and it still maintains a lifelike appearance, I think it must be a supreme powerhouse in the future. Xia Mu stepped forward and silently sensed for a moment, making sure that the divine soul fire in his skull had been completely extinguished, and then he let down his guard.

"You guessed right, this person is indeed a supreme powerhouse, and at least a supreme powerhouse in the immortal realm. Mu Qingxian observed for a moment and said lightly.

"How do you say that?" Xia Mu was startled, looked at Mu Qingxian and asked.

"This supreme powerhouse did not die naturally, but was sealed by someone and died by using the power of time to wear it out. With a wave of Mu Qingxian's incense sleeves, a violent hurricane suddenly blew in the stone cave, blowing away all the dust around the skull, revealing a huge formation underneath, and the position of that head was the center of this huge formation.

"Seal?" Xia Mu only noticed the huge formation in the stone cave at this time, and the pupils in his eyes couldn't help but shrink slightly.

"This is the 'Three Souls, Seven Spirits and Six Dao Seals', which is specially used to seal the powerhouses above the immortal realm. It is rumored that this formation is to split the monk's body into six parts, that is, the 'six paths' in the 'Three Souls, Seven Spirits and Six Dao Seals', which are the head, body, and limbs, and then the three souls and seven spirits are sealed in these six parts, and finally locked with the formation. Mu Qingxian said in a slightly deep tone.

"You're not going to tell me that this guy isn't dead yet, are you?" Xia Mu asked with a chill in his heart.

"I don't know about this, but if this place is really the ruins of the Ancient Starry Sky Immortal Dynasty, then most of this person is dead, unless ......" Mu Qingxian glanced at Xia Mu, and said in a slight tone: "Unless this guy is a powerhouse in the Eternal Realm, then it is possible that he is not dead." ”

As soon as these words came out, both of them fell into silence for a while, just looking at the head of the mysterious creature locked in the formation, as if they no longer paid attention to everything.

At this moment, a faint black mist spread out on a stalactite pillar a few feet above the heads of the two people, and then a mysterious ghost creature wrapped in black mist appeared, its limbs were clinging to the stalactite pillar like a gecko, and its breath was constricted, lying there motionless.

Xia Mu and the others were still observing the head of the mysterious creature, and they didn't seem to be aware of it, but when they saw a black shadow inexplicably appearing on the ground, the corners of their mouths invariably showed a sneer.

Swish!

It was at this moment that two black shadows suddenly threw out of the mysterious ghost's mouth, and they struck Xia Mu and Mu Qingxian respectively with lightning speed.

This mysterious ghost creature actually wanted to kill Xia Mu and Mu Qingxian in a one-time sneak attack.

At this moment, Mu Qingxian's body was full of blue light, and he took the blow of the mysterious ghost creature unscathed, while Xia Mu was too void under his feet to spread out, not only dodging the whipping of the black shadow, but at the same time, his body appeared in front of the mysterious ghost in a flash, and with a grasp of the void in his palm, the incendiary flame swept out, turning into a big hand, and the mysterious ghost was killed with just one blow, and even the stalactite pillar that was attached to it was destroyed.

"Your spiritual fire is too powerful for the restraint of corpse ghosts, and a ghost in the middle stage of the Shentai is so easily tortured and killed by you. Seeing the ghost thing that was instantly annihilated under Xia Mu's attack, Mu Qingxian said with some fear.

Her cultivation is Mu Xing, from a congenital point of view, she is just restrained by Xia Mu's flames, if Xia Mu's cultivation is a little higher, it will be very threatening to her, fortunately, the two have reached an agreement to join forces in advance, plus her seemingly indecent temptation some time ago, so she is not worried that Xia Mu will become an enemy.

"Let's go, there's nothing of value here, let's find the exit quickly. Xia Mu glanced at Mu Qingxian meaningfully, and said with a light smile.

"Hmm. Mu Qingxian nodded, and then the two left along the passage on the other side of the stalactite cave.

Shortly after the two left, a shadow suddenly emerged from the ground.

The shadow is pitch black, has no fixed form, and looks like a black mist.

This shadow first glanced at the stalactite pillar destroyed by Xia Mu, and then at the head of the mysterious creature that was locked in the center of the formation, and suddenly pounced upward.

A strange scene appeared.

At the moment when the shadow swooped down on the head of the mysterious creature, purple lightning suddenly rose from the underground formation, turning into a lightning shield, blocking the shadow from the outside.

The shadow rolled and was knocked backwards by the lightning mask, but it was unscathed.

But at this moment, the spiritual light flashed in the seemingly abandoned formation, and at the same time, there were also formations on the walls of the entire stalactite cave, densely packed, almost all over the entire stalactite cave.

Seeing that the large array was about to operate, but at the stalactite pillar that was destroyed by Xia Mu before, a roar suddenly burst out, and it could be seen that the formation there was broken due to the destruction of the stalactite pillar, which caused problems in the process of operation of the large array, and it actually stopped on its own in the middle of operation.

At the same time, due to the sudden cessation of the Great Array, the lightning mask that had originally blocked the shadows also disappeared.

Seeing this, the shadow immediately roared and pounced on the mysterious creature's head again, this time without the obstruction of the lightning mask, the shadow smoothly sank into it along the seven orifices of the mysterious creature's head.

After a while, the head of the mysterious creature was no longer a lifeless dead thing, but its eyelids moved slightly, and then it suddenly opened, and there was blood light shooting out from it, easily piercing the iron chain that locked the skull, and it was only at this time that the head of the mysterious creature flew into the air with a swish, staring at the direction where Xia Mu and the two left, and fell into deep thought.

And just as Xia Mu and the others were looking for the exit, an earth-shattering roar erupted from the depths of a lake somewhere in the Heavenly Fire Domain, and three peak cultivators of the Shentai Realm were using various spiritual weapons to attack a unicorn beast with a fiery red body and a lion-face, horse-like body, and dragon claws.

And this unicorn beast was not only unharmed in the face of the joint attack of the three Shentai peak monks, but also spit purple red flames and swept towards the three Shentai peak monks, making the three of them scramble for a while.

And a few feet in the air not far from the three people and one beast, a monk shrouded in black robes put his hands behind his back and looked at this scene indifferently, as if he did not intend to help.

"Big brother, if you don't make a move, we really won't be able to bear it, the defense of this fire lin beast is too terrifying, and our attack is no threat to him at all. One of the peak cultivators of the Divine Platform who was besieging the Fire Lin Beast took the time to shout at the black-robed monk in mid-air.

"This fire lin beast belongs to an elite-level high-level fierce beast, which is just equivalent to the peak of our Shentai realm, the three of you can't beat one of it together, the actual combat ability is too poor, just take this opportunity to hone it, otherwise it will be easy to suffer losses when you fight with people in the future." The black-robed monk said indifferently.

However, as soon as his words fell, the fire lin beast suddenly let out a roar of rage, and at the same time opened its mouth and inhaled, the spiritual power in all directions suddenly gathered, turning into a thunder and lightning ball the size of a basin, and then the fire lin beast's head flicked, and this thunder and lightning light ball shot out like lightning, killing the three peak cultivators of the divine platform.

"Thunder and Fire Dual-Attribute Fierce Beast?" Seeing this scene, the black-robed monk in mid-air let out a cry of surprise, and immediately shouted in a deep voice: "Xinghai, you three retreat, this mutated Fire Lin Beast will be handed over to me to deal with." ”

As he spoke, the black-robed monk stared at the ball of lightning light that came from the lightning with a flat gaze, and his hands slowly stretched out from his sleeve robe, and between the infusion of spiritual power, a faint black light appeared on his palm, and he quickly slashed towards the void.

Hearing only the sound of 'snort', the black-robed monk's palm was so sharp that he easily split the thunderbolt ball in half, and then only saw a flash of human figure, and the black-robed monk quickly rushed towards the fire beast.
