Behind the ruins of the Ancient Immortal City, Xiang Hong was standing in front of an open space at the moment. Pen, fun, and www.biquge.info

In front of him was a huge circle carved into the surface of the rock, the pattern of the circle was incomparably intricate, and the lines were drawn deep into the surface.

The surrounding stone pillars and houses had long since decayed and collapsed, but the circle on the ground was intact and undamaged.

This large array and the teleportation array inside the Thousand Peaks are mutually reinforcing, as long as the spirit crystal is inserted to activate the formation, the monk can shuttle back and forth between the two formations.

At this moment, in the large array in front of him, someone had already placed a sufficient amount of spirit crystals, but this huge pattern did not react at all, neither the light flickered, nor the spiritual power flowed, it seemed that the entire large array had completely failed.

"Eight thousand, can you analyze the problem with this teleportation circle?" Xiang Hong said in a low voice.

Eight thousand leaped out of the void, flashing with red light, and scanned the huge magic circle in front of them for a long time.

"The magic circle diagram is complete, there are no problems, it is speculated that the teleportation circle on the other side is malfunctioning."

Xiang Hong suddenly felt depressed when he heard this, there was a problem with the teleportation array on the opposite side, and now he couldn't get in, wouldn't it be completely out of order.

"Is there any other way to enter the Senju Peak area?" Xiang Hong asked with a frown.

"There is not enough information to infer it, so it is recommended to wait in place for the time being." Yachimi replied in the air.

Xiang Hong shook his head, now is not the time to wait on the spot, after all, there is a murderous Yi Jian Peak chasing after him.

"I'll look along the edge of the Thousand Peaks and see if there are any other passages." After Xiang Hong made up his mind, he unfolded his wings and rose in place, and prepared to fly out of the city.

Just as he was about to start, Xiang Hong's face suddenly changed, he saw a huge smoke and dust on the distant skyline, blowing a violent hurricane, and there were more than ten rays of light at the front of the hurricane, which were flying towards Gu Immortal City at a rapid pace.

The hurricane was overwhelming, and among the more than ten rays of light, a few of them were a little slower, and they were instantly engulfed by the hurricane and disappeared, and the remaining seven or eight rays of light suddenly accelerated again, using their desperate strength to gallop towards Gu Immortal City!

In an instant, these seven or eight rays of light had fallen into the city, and the monks among them fell into the square, among them was an old man with gray hair, who was the monk who had invited Xiang Hong to go out to hunt demon beasts.

The old man was now disgraced and panicked, staggered up from the ground, and shouted at the onlookers who could not figure out what was going on.

"The monster is here! Countless monsters! ”

As the old man's words fell, the violent hurricane roared, the sky suddenly darkened, and the howling of the wind sounded in mid-air, mixed with the howling of demon beasts, which made people feel chills.

The old man shouted loudly, "Quickly use the spirit crystal to activate the protective magic circle on the surrounding city walls!" ”

Xiang Hong heard the old man's shout, and suddenly remembered that there was a description on the map that Yun Xiangrong gave him, Gu Immortal City had the blessing of the formation, and after activation, it had extremely strong protective capabilities.

Some clever monks around had already rushed to different directions, and there were a total of nine magic circles on the entire Gu Immortal City, and all of them were activated in an instant.

Endless gloom shrouded above, howling continuously, and dozens of black qi had already rushed out of the haze and rushed towards the large group of monks in the ancient city.

These monks in the ancient city sacrificed the magic weapons in their hands one after another, and suddenly hundreds of rays of light rose, facing the dozens of black gases, a piercing howl sounded, a burst of blood rain fell in the air, and a large number of demon beast stumps fell from the air.

Subsequently, the entire Ancient Immortal City was bounded by the city, and a faint white light curtain appeared, enveloping the entire ancient city in it. The light curtain gradually solidified, and although there was still a continuous impact of black gas outside, it was never able to break through this layer of light curtain.

The surrounding haze became thicker and thicker, and the entire Gu Immortal City was shrouded in endless haze, instantly like night, leaving only the faint light from the light curtain above, vaguely illuminating the scenery in the city.

Xiang Hong put away the yellow sand scimitar, walked to the old man's side, and asked, "What is the origin of this demon beast?" ”

The old man gasped for a long time out of breath before he spoke: "We originally planned to hunt demon beasts, but we didn't expect to go out not far away, and we ran into a large group of demon beasts head-on. ”

Xiang Hong continued to ask, "How many demon beasts are there?" ”

The old man shook his head and said, "There is a demon wind and haze, I can't see it clearly, but there must be a lot, and there are at least seven or eight demon beast breaths in the Jiedan Realm just perceived." ”

Xiang Hong frowned, seven or eight Demon Beasts of the Jie Dan Realm, plus a large number of other Demon Beasts, I am afraid that the more than four hundred monks in this ancient city will be able to defeat even if they gather all their strength.

What's more, the monks here come from all over the Central Plains and don't know each other, so it is simply empty talk to let these people unite and fight the demon beasts selflessly.

Now that the teleportation circle has failed, it is really not going well to catch up with the demon beasts besieging the city!

However, this layer of light curtain in the ancient city, although it looks bleak, is extremely solid, and even though the demon beasts in the haze around them howl angrily and continue to hit, they have never stood still.

It seems that the only way to do this is to wait for this large group of demon beasts to retreat, as the old man said, and then make plans.

Xiang Hong found a secluded ruin, meditated cross-legged on a broken stone slab, and began to meditate to adjust his physical and mental state to the best.

At present, the demon beasts have not been able to attack the Gu Immortal City, but there are already a lot of strange things happening in the secret realm, and no one can completely grasp what will happen in the next moment.

The demon wind around Gu Immortal City surged, flying sand and stones, which lasted for a full hour, and it never weakened.

Some of the more brain-thinking monks had already realized that the demon beasts outside were not passing by, but were specifically coming towards this Gu Immortal City!

The monks in the square suddenly let out a commotion, Xiang Hong opened his eyes and looked, and found that the light curtain above the ancient city began to become dim, looking crumbling, it seemed that the spirit crystals that had activated the protective array before had been almost consumed, and new spirit crystals needed to be replenished.

The monks in the square began to look left and right, looking at each other.

Generally, the protective arrays of the sect use spiritual veins as the source of spiritual power, so they can always maintain operation, and the protective arrays like Gu Immortal City, which have no source of spiritual power, must constantly replenish spiritual crystals in order to continue to operate.

There are a total of nine array diagrams in a circle around the surrounding city, and it takes more than a thousand spirit crystals to activate each formation diagram, and it is good to say that it is good to activate it once before, but if it continues to be stalemate like this, it will be a huge expense to replenish the spirit crystals of nine array diagrams every once in a while.

"Everyone, please listen to the old man!"

In the center of the ancient city, a slightly old voice suddenly sounded, and everyone turned their heads to look and found that it was the old man who had fled back before.

The old man stood on a broken stone platform at this moment, and said loudly to the people around him: "The array map on the surrounding city walls needs to be replenished every three quarters of an hour, and a total of ten thousand spirit crystals are needed for each replenishment. ”

There was a whisper in the crowd around him, and although most of them were aware of this, it was inevitable that someone would say it in public.

The old man looked at the crowd around him, raised his voice, and said loudly: "Old decay Lu Wu, I am willing to sacrifice my personal spirit crystal to supplement the city circle this time!" ”
