Those two magician-level masters who were sitting in the valley guarding the veins of the Xuanyin Demon Crystal Mine made Liu Yu very jealous, and the strength shown by those two magicians was stronger than him.

If it is a person, Liu Yu still has the strength to fight, and with his combat skills and strong martial arts, he is not necessarily not the opponent of the magician. But the other side is not one person, but two people.

But if the two magicians joined forces, Liu Yu would not have any chance of winning at all. Liu Yu didn't want to put himself in danger, so he had to lurk on Demon Moon Island and wait for the opportunity.

After the battle of the monster's large-scale attack, the demons in the valley suffered many casualties. There are hundreds of demons, and now there are only seventy or eighty people left.

Except for the demons who often mine the Xuanyin Demon Crystal, there are not many demons in the valley who can fight, and there are about less than fifty people.

Mining Xuanyin Demon Crystal, you don't need too many people, because in the magic crystal vein, the Xuanyin Qi is very powerful, if you stay in the vein for a long time, the whole person will be frozen by the cold qi emitted by the Xuanyin Qi, and there is a danger to life.

Unconsciously, another half a month has passed, sitting in the cave he has opened up, and his luck has been adjusted. However, it was difficult for him to enter the deep cultivation.

The demon surname that originated from the underworld between heaven and earth made it difficult for him to calm down, unless he entered the inner space, otherwise, when he cultivated, he would be affected.

Liu Yu didn't know where this demon surname came from, it seemed to come from between heaven and earth, where the source of the demon surname was, Liu Yu couldn't sense it at all.

Not only Liu Yu, even the demons in the Extremely Cold Demon Domain, most of them don't know where the demon surnames between heaven and earth come from.

"Boom ......" Suddenly, Liu Yu was awakened by the dull thunder coming from outside the cave, and then, he stood up from the ground, pushed away the boulder blocking the entrance of the cave, and walked out.

What he saw in front of him suddenly surprised Liu Yu, at this time, dark clouds covered the sky, and black lightning split down from the clouds, which looked extremely evil and gloomy.

The tumbling dark clouds fell lower and lower, as if they had touched the ground, making people feel a heavy sense of oppression, as if the 100,000 mountains were slowly descending.

There was no sound in the heavens and the earth except for the rumbling thunder, and the Demon Moon Island seemed to have lost its voice, and all the monsters on the island seemed to have been hidden.

Unspeakable palpitations, soul-shattering! A terrible storm is coming.

Liu Yu looked up at the dark sky in front of the entrance of the cave, and the terrible celestial phenomenon in front of him suddenly made him feel uneasy, and he had a faint premonition that something bad was about to happen.

"Boom!"

Lightning and thunder roared between heaven and earth. Criss-crossed black lightning bolts, cutting through the equally dark sky. The pouring rain poured down, a curtain of water between the heavens and the earth, and the storm began.

Whining...... It was as if a fierce spirit was crying out, and the wind around it sounded a little scary.

Black lightning can also illuminate the heavens and the earth, and when the lightning passes, the heavens and the earth fall into darkness, and you can only hear terrifying sounds from all directions, and you can't see any scenery.

It was as black as ink, and the five fingers could not be seen when he stretched out his hand, and the heaven and earth seemed to be covered by a dense black cloth.

"Boom!"

The thunder shook the heavens and the earth, the lightning tore the void, and when Liu Yu was about to re-block the entrance of the cave with a boulder, with the deafening thunder, Liu Yu seemed to hear the sound of fighting floating from afar.

The voice...... It seems to have come from the ancient ruins on Moyue Island, the ancient ruins in the valley, is there any secret? Liu Yu couldn't help but frown.

The strange sound coming from the direction of the ancient ruins aroused Liu Yu's curiosity, so Liu Yu walked into the storm and rushed towards the direction where the ancient ruins were.

All the rain could not splash on Gu Fei's body, and there was an invisible force that kept the rain away.

Liu Yu walked silently in the darkness, like a ghost under the night. Along the way, he didn't encounter a single monster, and this abnormal phenomenon made Liu Yu even more uneasy, and it seemed that something was really wrong.

Liu Yu walked forward cautiously, and finally, he came to the outside of the valley where the ancient ruins were located, and at this time, Liu Yu deeply felt that the entire valley was shrouded in a majestic power fluctuation.

Under the shining light of thunder, ancient figures began to appear in the valley, wearing ancient armor and holding divine weapons, fighting fiercely among the ancient ruins in the valley.

It is not real, flesh and blood people, Taoist figures, faint and unreal, but they do not reveal the fluctuations of the soul, these figures, it seems that they are not the existence of primordial gods or ghost bodies.

In fact, it is a kind of mental power, a kind of mental power that does not dissipate after death, and it is a special existence that has no real body formed by divine thoughts.

The dark sky was extremely oppressive, and Liu Yu stood on a big mountain next to the valley, looking at the incredible scene in the valley in shock.

It's unbelievable, the shouting and killing sound from ancient times still lingers in his ears, making his blood boil, even if he has been dead for endless years, and the bones are gone, but the divine thought has gone through endless years, and it still does not dissipate.

The illusory figure was in a fierce array, no flesh and blood flying, no blood splashing, only a terrifying shout and the sound of weapons colliding.

There is no doubt that this ancient relic was destroyed in a war.

In the midst of the storm, Liu Yu suddenly felt a spatial fluctuation coming from the ancient ruins below. Liu Yu, who sensed this spatial fluctuation, suddenly changed color.

The fluctuation of the space came from an ancient altar in the ancient ruins, Liu Yu's face was even more ugly, the ancient altar had some connection with the nameless ancient temple in the death swamp of the purgatory realm.

The ancient teleportation array in the nameless ancient hall is connected to the altar, since Liu Yu and the old turtle can stimulate the ancient teleportation array and cross the border, then it is difficult to ensure that those "kings" in the death swamp who control the nameless ancient hall will not come to this world through the ancient altar.

"Could it really be that a king can't come out of the purgatory realm!?" Liu Yu was secretly surprised, and his attention immediately shifted from those faint and unreal warriors to the ancient altar.

What Liu Yu was worried about still happened, the ancient altar began to reveal the runes of the Dao Mysteries, and the space above the altar gradually became unstable, and in the end, the cracks in the Dao space began to appear in the void above the altar.

"Roar!" The void shattered, and from the shattered void, a sharp roar suddenly sounded, and the entire valley shook, and the howl was so abrupt, as if it was stirring from the nine heavens away, and it seemed to pass through the ancient desolate shattered void.

Then, in the midst of the earth-shattering thunder, the figure of a hideous undead creature began to walk out of the shattered space above the altar.

It was a white bone skeleton, a bone body as crystal as a divine jade, exuding an incomparably powerful aura, and in the skull, a brilliant soul fire was as dazzling as a round of flames, as strong as a divine flame.

This is definitely a "king" level undead king.

Liu Yu was shocked, he hurriedly hid, and the lilac vertical mark in the center of his eyebrows began to reveal bursts of inner space power like water waves, enveloping himself.

Only in this way can you escape the induction of the immortal king. There is a king coming out of the purgatory, and the Extremely Cold Demon Domain is afraid that there will be an unimaginable storm.

The spatial passage formed by the shattered void was rapidly disappearing, and after the undead king walked out of the spatial passage, he immediately startled the surrounding scene.

Countless faint figures were fighting, and the terrifying killing intent that came out, even this white bone king felt extremely shocked and incredible.

The entire ancient ruins suddenly shook violently, and then, an incomparably powerful faint figure appeared above the ancient ruins.

The tall figure that rumbled and gave people an unreal sense stared at the white bone king on the altar, and the terrifying killing intent formed a killing light, shooting towards the white bone king on the altar.

The soul fire in the skull of the White Bone King flickered violently, and then, he stretched out a crystal jade bone palm and directly greeted the terrifying killing intent that shot out.

"Bang!"

The jade bone palm and the brilliant killing light instantly collided together, and a scene that Gu Fei couldn't believe happened, the white bone king on the altar was actually bombarded off the altar by that killing intent.

The killing light formed by the terrifying killing intent made the jade bone palm of the White Bone King covered with cracks like spider webs, as if it could be shattered at any time, it was an immortal bone body that was harder than divine iron.

The Bone King who was knocked off the altar roared angrily, he was in great trouble, and he fell into the countless ancient figures who were desperately fighting below the altar.

It is the faint and unreal figure of the ancient warrior who has been baptized by endless years, and the terrible killing thoughts that still do not disperse and never go out.

In this stormy dark night, an incomprehensible vision appeared in the ancient ruins of this side. This shows that the relics left over from ancient times hide important secrets that no one knows.

The White Bone King who fell from the altar was hit with an unimaginable impact, a terrifying killing intent, directly attacking the soul fire in its skull.

It was an attack from the soul, which was difficult to resist, and the White Bone King was suddenly hit by an unimaginable blow, and the soul fire in the skull gradually dimmed.

The tall figure that blasted the White Bone King down from the altar from the altar was forced in front of the White Bone King again, and the terrifying killing intent once again formed a terrifying killing light, directly hitting the White Bone King's chest.

"Click!", the white bone king's ribs were immediately broken three times, the bone body was hit with unimaginable impact, and cracks appeared on the bone body.

The White Bone King was directly blasted out of the way, and with a sound of "Canopy!", it just happened to fall on the edge of the ancient ruins on this side.

The White Bone King was hit hard one after another, and he still dared to stay there, and rushed out of the ground directly, and then turned into a white light, and rushed out of the valley in a panic. (To be continued.) )
