Luo Qing flew towards the pillar of heaven from the three of them, because they didn't know the nature of this pillar of air, they didn't get too close, but separated by a distance, but just like that, it was enough for them to find something strange.

This pillar of air is the ghost gas that spews out from the ground, and the large array is pressed on the underground ghost city, and most of the ghost qi is suppressed by the formation.

The three of them could feel a bone-eroding cold coming from a distance, Ye Xiliang took out a jade bottle, a wisp of light smoke rose, and the mist was like silk, forming a thin cocoon around them, blocking this yin qi outside.

In the midst of the ghostly qi, you can faintly hear a hoarse cry, like a cat's meow, and even a fog shadow rushes out of the air hole.

The three of them didn't know exactly what those fog shadows were at first, but they soon saw them with their own eyes.

Clusters of large and small ghostly fires loomed in the ghostly aura, floating in their direction, and from a distance, they could only see a little bit of dark green firelight, and when they got closer, they could find that these things looked like lanterns, and their bodies were like a layer of miserable white human skin, all of them had noses and eyes, and their mouths occupied most of their bodies, and the cluster of firelight was hidden deep in their mouths.

"It's a lantern ghost of the ghost clan. ”

Lu Heng recognized this thing at a glance.

Although ghost cultivation is not common in the world of cultivating immortals, it can't be said that there is none, they are transformed from people, but they re-enter the Tao in a different way after death, and there is not much difference from the monks in the three thousand avenues, ghost cultivation is recognized by human cultivation, but this kind of thing is condensed by innate resentment, joy ** anger, and cruelty to living beings, if you can see it, it is bound to be punished.

Over time, the ghost clan was basically invisible in the ordinary immortal cultivation world, and only the ghost clan existed in the underground ghost city under the Void Immortal Great Array, and because of the Great Array, it was banned here.

There are very few records about the ghost clan in the world, but the Thunder God Dao Pagoda has been inherited for tens of thousands of years, and the classics in the library pavilion are enough to be called a vast sea, but Lu Heng has seen some cold books, among which there are recorded types of ghost clans.

The number of lantern ghosts is extremely large, densely packed in a large area, and they feel the popularity, just like dogs see meat and bones, and rush over.

Lu Heng fanned it without thinking about it, and a thundercloud suddenly condensed in mid-air, the electric light flickered between the clouds, and the next moment countless large and small thunder rods and drizzles fell, densely pouring down, hitting the body of the lantern ghost, their skin was penetrated by the thunderstorm, and the full and swollen lantern ghost suddenly became like a deflated ball, quickly dried up, turned into wisps of black gas and floated in the air, and the screams came and went.

Luo Qingli and Ye Xiliang also made moves, but whether it was the Ice Sword Qi or the Sonic Attack, they could not cause substantial damage to these Lantern Ghosts.

Luo Qingli squinted his eyes, and once again sacrificed the Pure World Lotus Lamp, as soon as the Buddha's light came out, those lantern ghosts didn't even have time to howl, and they were already in ashes.

Although a wave of lantern ghosts was annihilated, there were still fog shadows gushing out of the ghost qi pillar, and they all looked at this scene with a somewhat solemn expression.

Lu Heng pursed his lips and said, "Let's get out of here first." ”

The three of them quickly moved away from the air pillar, and when they walked out of a considerable distance, Ye Xiliang groaned: "I heard that there are ten ghost cities under the Empty Netherworld Great Array, and the ghost clans and ghost cultivators in the city coexist, and there are countless evil ghosts, just those ......"

"Lantern ghosts only belong to the low-level ghost clan. Lu Heng whispered: "Every hundred years, the underground ghost city will enter the night of the canopy, during this period, the strength of the ghost clan has increased greatly, but the effect of the Void Array has been weakened, there may be high-level ghost clans who take advantage of this opportunity to leave the underground, but those lantern ghosts are not capable of passing through the barrier at the entrance of the ghost city." ”

The sudden appearance of the lantern ghost should be due to the leakage of the air eye, which is likely to lead to the underground ghost town.

It may be that some low-level ghost clans have come out now, but what about later? If the high-level ghost clans also came to the formation through this place, wouldn't they, the Jindan monks on the periphery, be equivalent to pigs and sheep waiting to be slaughtered?

I'm afraid there's trouble in the formation.

The three of them crossed their minds at the same time.

Luo Qingli thought for a while and said: "The big array has the function of self-repair, although it is nested layer by layer, but it is also independent, and there will never be a situation where any link is missing, the formation will not be able to operate or collapse, and the qi eye like that will heal itself after a period of time." ”

This once-in-a-century trip to the Void and Netherworld Great Array was not in essence in accordance with nature, but the monks from the outside world coveted the treasures in the array, and forcibly broke the barrier when the formation was weakened, so that they could enter.

If the formation is compared to a person, then, the night of the canopy every hundred years is the weakest time for this person, and at this time, the monks of all directions let "it" be injured on this basis, and the formation is even weaker, but it is also strong enough to survive this time, and "it" is a good man again.

For tens of thousands of years, generations of monks have done this, and the Great Array is still standing.

But how long this repair process will take, Luo Qingli can't say for sure, as for whether it can be artificially tried to temporarily seal it...... The pressure near the air eye is amazing, not to mention the seal, it is difficult to get close, maybe the formation master of the Yuan Infant Stage is expected to give it a try, but they are out of line.

However, Lu Heng remembered something, "I heard Master say before that underground ghost cities have clear hierarchies, and the deeper you go, the higher the level, and this qi eye is at most to open up the top layer." ”

Therefore, the people who came out were all low-level ghost clans.

If that's the case, then it's okay, as long as there are no high-level ghost clans coming to the periphery, their situation won't be too bad.

Thinking so, the three of them wandered around the periphery of the large array again, and it didn't take long for them to discover that there was more than one aura like this on the periphery.

Dealing with the ghost clan, ordinary spells have little effect, but the spells of the second system of gold and fire are more useful, but not every monk can use this kind of spell, even if the low-level ghost clan is vulnerable, but they can't stand their large number and large base, so that they occasionally see a monk being chased by a group of low-level ghost clans.

With the Pure World Lotus Lantern there, the three of them didn't have such troubles, they stopped and stopped, still exploring the periphery, but after more than half a month, the middle-level ghost clan began to appear on the periphery, and they just bumped into such a team.

It was a group of women dressed in red, with flying black hair and long sleeves, and their posture was graceful from a distance, but in fact, they were extremely ugly, and their bloody mouths occupied most of their faces, except for the only one eye on their foreheads, which was only white and not black, and was covered with bloodshots.
