The man in gray and the woman in purple took action at the same time.
The formation flag on the ground emits two completely opposite yin and yang forces, which merge with the void.
Gradually, gray mist began to fill the void, shrouding the two of them.
Looking from the outside, the two of them blended perfectly into the heaven and earth, with no breath escaping.
Shortly after the two went into hiding.
In the dark void, a scarlet eye suddenly opened.
The eyes looked at the area where Lin Zheyu was, and disappeared in an instant, as if they had never appeared.
"The strong men of the Flame Demon Tribe are here!"
The man in gray clothes hiding in the formation had a solemn look in his eyes.
The Flame Demon Tribe is one of the most powerful races in the Xuanhai Territory. Their number is not as large as that of the human race, but their individual strength is very powerful.
This ethnic group, like the Blood Shura tribe, is a warlike and murderous race.
The number of their tribe was not large, largely due to their willingness to fight and kill, which resulted in a large number of tribesmen dying before they had time to grow up.
But this also led to the fact that every flame demon clan that grew up was terrifyingly powerful.
"Not only the Flame Demon Clan, I also sensed a wave of fluctuations from the Mingguang Clan just now..."
The woman in purple said.
The Mingguang Clan is also one of the strongest ethnic groups in the Xuanhai Region.
Those who dare to enter this dark abyss to explore are all the most gifted among the most gifted.
Even if the two of them mastered the array flag at the Tianzun level, they would not dare to underestimate these geniuses.
They can take advantage of loopholes in the rules and bring in magic weapons that exceed their own strength, and other strong people can do the same.
"Hey, one by one, they all came here without knowing what opportunities were hidden here."
The man in gray clothes smiled coldly.
Of course, he ignored himself and his companions, who were the first to arrive.
At the beginning, they had no idea what opportunities lay here.
But just now, the man in gray found some familiar traces from the formation restrictions here.
There is probably something amazing hidden here!!!
…
In the dark abyss, undercurrents surge.
When Lin Zheyu was exploring previously, the huge noise caused by the self-destruction of his clone attracted many powerful people.
However, he didn't care too much.
"Here comes another one..."
Lin Zheyu's steps paused slightly, and he continued to point his right hand towards the void in front of him, exploding a key node.
While analyzing and breaking the restrictions of the formation here, he was also always paying attention to the movements of the outside world.
Lin Zheyu would not be so naive as to think that he was the only one who could venture into this dark abyss.
He had just entered the wonders of the Nightmare City, and in less than ten years, he had adapted to the concentration of nightmare power in the black abyss.
There must be many strong men who entered this wonderful scene earlier than Lin Zheyu, and they must be able to withstand the erosion of the power of nightmares in the black abyss.
However, Lin Zheyu was not too worried.
The power of nightmares in the Black Abyss is extremely strong, and fighting here is not a wise choice.
Those guys won't take action easily if they don't see enough treasures or opportunities.
Puff puff puff!!!
Lin Zheyu kept pointing with his fingers, and the endless martial arts divine patterns turned into blood-colored mist, which continued to penetrate into the nearby void.
Time passes slowly...
More than a month later, Lin Zheyu shook his head and felt that his condition was declining rapidly.
This is caused by excessive erosion by the power of nightmares.
Continuous attacks, constant analysis, and breaking of the formation restrictions here caused the power of nightmare to intensify the erosion of him.
In just over a month, he felt like he couldn't hold on any longer.
Phew~~~
Lin Zheyu breathed a sigh of relief, not daring to stay here any longer.
Four clones walked out of his body and sat cross-legged at different true eyes, replacing the main body to maintain the formation restrictions that were finally controlled.
The formation restrictions here are extremely powerful, and they also have the ability to repair themselves.
Although it is extremely slow, under the influence of its self-healing ability, it is eroded by the extremely rich power of nightmare.
After Lin Zheyu left, without his support, the results achieved with great difficulty would be in vain.
…
"He left..."
The woman in purple glanced at Lin Zheyu's leaving figure and looked at her senior brother with a smile.
"Don't worry, wait for other fellow Taoists to take action first."
"There is probably something great hidden here, but it is not easy to break through the formation restrictions here."
The man in gray said with a smile.
He pondered for a moment, looked at his junior sister and asked: "How long can you hold on?"
What he asked was how long the purple-clothed woman could sustain herself in such a strong environment of nightmare power without falling into sleep.
"If we don't take action, there is no problem in maintaining it for three months." The woman in purple said.
"Three months... is a bit short..."
The man in gray clothes shook his head and said immediately: "Let's go out first."
"Come back after you have refined the power of nightmare in your body and raised yourself to the best condition."
"good!"
The woman in purple nodded.
The two of them controlled the formation flags and surrounded them. Under the cover of the formation flags, they quietly galloped out of the black abyss.
…
"It's Chang Zichen and Mu Yunshi, they are here too..."
In the darkness, a scarlet eye suddenly opened and looked in the direction where the man in gray and the woman in purple had just left.
"They are so well hidden, I didn't even notice them just now." Another voice came.
"What kind of place is this? Are there any relevant records in your clan's classics?"
The strong man from the Flame Demon Tribe looked aside and asked calmly.
This is a humanoid creature with a red body, complex and mysterious patterns engraved all over its body, a body with six arms, and a ferocious red eye between its eyebrows.
"No, there are very few records about the Nightmare City in the clan, let alone this mysterious abyss."
The strong man hidden in the gray mist said calmly.
The mist surged, revealing the blurry figure of the opponent.
It was a huge creature with a dark body, a pair of wings on its back, and a shape similar to that of a wolf-dog.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! This is the strong man of the Sirius clan.
The Sirius clan is also one of the most powerful clans in the Xuanhai region.
"Then just wait."
"You will know when that human race breaks through the formation restrictions here." The strong man from the Flame Demon Clan said calmly.
"The formation restrictions here are quite good, but they are not easy to break. Whether that person can succeed is still unknown."
"You stay here and keep watch. I'll continue to search deeper. Maybe I'll find something else."
The strong man from the Sirius tribe said something calmly, swayed slightly, and disappeared in an instant.
The strong man from the Flame Demon Tribe glanced at him.
He pondered for a moment, moved slightly, and rushed out of the abyss.
It has been a long time since the powerful Flame Demon Clan entered here. He also needs to leave for a while to refine the power of nightmare that has eroded into his body.
The strong man from the Flame Demon Clan had originally planned to leave. It was on the way out that he sensed the movement here and quietly lurked over to observe the situation here.
However, as the strong man from the Sirius Clan said, after observing it, he found that the formation restriction here was indeed very powerful, and it was extremely difficult to break through it.
That human monk may not be able to break it open.
He secretly observed for a long time, but did not find any treasures or opportunities hidden in this formation restriction.
Therefore, it doesn't make much sense to continue to stay here.
but,
Before leaving, he had a slight thought, and hot liquid like magma seeped out of his body.
This hot liquid surged and turned into a clone, disappearing into the mist.
…
Soon, a month passed.
Lin Zheyu refined the power of nightmare that had eroded into his body and returned to the black abyss.
"Have everyone left?"
Lin Zheyu explored the surrounding area and was a little surprised.
Before leaving, there were several strong men hiding in the darkness nearby. Unexpectedly, after leaving, they all left.
According to the memory fed back by the clone, during the time he was away, several strong men tried to break through this formation restriction.
But they all failed.
The formation restrictions here are extremely powerful and cannot be broken if forced.
The unbridled explosion of powerful power will also accelerate the erosion of the power of nightmare on itself.
If you want to pass through this powerful array restricted area, you need to have certain attainments in the array restricted areas.
And obviously, the previous strong men didn't seem to be very good at this.
"Eh, no, there's a little mouse hiding. It's really deep."
Lin Zheyu's expression suddenly changed slightly, and a sneer appeared at the corner of his mouth.
His figure moved slightly and disappeared in an instant.
boom!
In the dark void, blazing fire suddenly erupted, and a body covered in flames shot out, speeding towards the depths of the black abyss.
"Want to run?"
"Leave me alone!"
The coldness in Lin Zheyu's eyes flashed across.
I thought that just a clone could hide in the dark and monitor what was going on here.
It would be too much to underestimate him.
Boom!
Lin Zheyu suddenly appeared behind the clone of the powerful Flame Demon Clan, and punched out fiercely.
The unparalleled power exploded, instantly blasting the clone of the Flame Demon Clan.
"The Fire Demon Clan..."
Lin Zheyu was holding a fist-sized, hot stone in his hand, which was left behind after the death of the powerful clone of the Flame Demon Clan just now.
It is the core of the other person's heart.
Putting away his core, Lin Zheyu carefully explored the nearby void again to make sure there was no one else hiding in the dark.
Then, his figure moved slightly and continued the unfinished task before.
Ten days later.
A vague wave came from a distance.
The man in gray, Chang Zichen, and the woman in purple, Mu Yunshi, who left earlier, also came back.
The two of them were shrouded in the formation flag, with no aura emanating from their bodies.
"Those guys are gone."
Mu Yunshi looked around and said with some surprise.
"They tried to break the formation, but they retreated because the formation restrictions in this area are not that easy to break."
Chang Zichen looked around and said with a smile, with a touch of confidence and pride in his eyes.
"If they knew what was hidden here, they would probably regret giving up so quickly!"
Mu Yunshi, a woman in purple clothes, said with a smile.
After the two left, they recovered outside the Nightmare City and refined the power of the nightmare, and finally figured out where this place was.
There are relevant records in their sect.
More than 10 million years ago, a brilliant genius entered the abyss here and discovered this area covered with powerful formation restrictions.
"Yes, this is most likely the location recorded in the classics."
Chang Zichen carefully observed his surroundings again and confirmed his suspicions again.
"The formation restriction in this area has a powerful covering effect. No wonder we didn't find this place when we passed by it before." Chang Zichen said.
One of their purposes for entering this black abyss was to find the area recorded in the classics.
Unfortunately, Chang Zichen and Mu Yunshi searched for it for a long time but could not find it.
On the contrary, Lin Zheyu accidentally triggered the restriction in this area after consuming a large number of clones.
Yes, it was just an accident that Lin Zheyu discovered this place.
It was when he used a large number of clones to search all over the place that he accidentally triggered the formation restriction here.
Lin Zheyu's clone failed to sense anything unusual in this area when passing nearby.
Until, his clone accidentally stepped into the area restricted by the formation and was forced to self-destruct.
Only then did Lin Zheyu discover the anomaly here.
After that, he sent out more than a dozen clones in succession, and without exception, they were all destroyed here.
"Senior brother, do we want to go in?" Mu Yunshi asked.
"wait!"
Chang Zichen smiled slightly.
"The formation restrictions in this area are not so easy to break, otherwise the senior at the beginning would not have returned in vain."
"Let's first let the fellow Taoist in front of us explore the path for us."
"When he fails, we will take action again." Chang Zichen said with a smile.
"What if he succeeds?" Mu Yunshi asked.
"Wouldn't it be better if we succeeded?"
Chang Zichen smiled meaningfully: "If it succeeds, we just need to stay here and wait for him to come out."
"Well, then let's start setting up!" Mu Yunshi said with a smile.
…
"Cave?"
Lin Zheyu looked ahead, feeling a little surprised.
As he continued to analyze and crack the formation restrictions, Lin Zheyu finally saw the scene in the center of the formation.
What appeared in front of me was an ordinary cave on the cliff.
"Could it be that this was the retreat place of a strong man from the Nightmare Tribe?"
Lin Zheyu's eyes moved slightly and he couldn't help but guess.
If this is really the retreat of a strong man from the Nightmare Tribe, perhaps the Nightmare Tribe's techniques can be found in it.
This is the original ancestral land of the Nightmare Tribe, and someone who can retreat here must be an incredibly powerful being.
This can be known just from the formation restrictions surrounding the cave.
It is just a residual scene projected by the long river of time, and the incomplete formation restriction has such powerful power.
You can imagine how powerful the complete formation restriction is.
The being who was in seclusion inside was very likely to be a powerful person at the realm lord level or even above!
"call……"
Lin Zheyu took a breath, and a dignified look gradually appeared in his eyes.
Although this place is just a residual scene, no one can guarantee that the strong man who was in retreat there will not have residual images projected out from the long river of time.
If this is really the retreat of a strong man in the Third Era...
"continue!"
Lin Zheyu did not hesitate at all and continued to try to break the formation restrictions here.
No matter what, we have to go inside and take a look first.
Since this is a wonder at the spiritual transformation level, the dangers that arise will not be too high.
Even if there is a powerful being from the third era who is projected from the river of time, Lin Zheyu will have to fight first!
Boom!
Lin Zheyu stepped out with his right foot and punched the void in front of him.
At this point, the power of the formation restrictions has become more and more powerful. With just one finger, it is no longer possible to poke the key nodes where the formation restrictions meet.
