Chapter 774 Cave
……

The man in gray and the woman in purple attacked at the same time.

The flags on the ground emitted two completely opposite yin and yang forces, which merged with the void.

Gradually, a gray mist began to fill the air, enveloping the two of them.

Seen from the outside, the two of them blended perfectly into the world, with not a single breath escaping.

Soon after the two hid.

In the dark void, a scarlet eye suddenly opened.

The eyes glanced at the area where Lin Zheyu was, and disappeared in an instant, as if they had never appeared.

"The strong men from the Flame Demon Clan are here!"

The man in gray who was hiding in the formation had a solemn look in his eyes.

The Flame Demon Clan is one of the most powerful races in the Xuanhai Region. Although their population is not as large as that of the human race, their individual strength is very strong.

This ethnic group, like the Blood Shura Clan, is a warlike and murderous race.

Their population was small, largely because they were warlike and murderous, resulting in a large number of members dying before they had a chance to grow up.

But this also resulted in every Flame Demon that grew up becoming extremely powerful.

"Not only the Flame Demon Clan, I just sensed a wave of fluctuations from the Bright Light Clan..."

The purple-clad woman spoke up.

The Mingguang Clan is also one of the strongest clans in the Xuanhai Region.

Those who dare to enter this black abyss to explore are all geniuses among geniuses.

Even if the two of them mastered the formation flags of the Heavenly Venerate Realm, they would not dare to underestimate these geniuses.

They can exploit loopholes in the rules and bring in magical weapons that exceed their own strength, and other strong people can do the same.

"Hey, one by one, they all rushed here without knowing what opportunities are hidden here."

The man in gray smiled coldly.

Of course, he ignored himself and his companion, as they were the first to arrive.

At the beginning, they didn't know what opportunities were hidden here.

But just now, the man in gray discovered some familiar traces from the formation restrictions here.

There is a high possibility that something extraordinary is hidden here!!!

……

In the dark abyss, undercurrents surge.

When Lin Zheyu was exploring previously, the huge noise caused by the self-detonation of his clone attracted many powerful people.

However, he didn't care too much.

"Here comes another one..."

Lin Zheyu paused slightly, and continued to point his right hand towards the void in front of him, poking a key node.

While analyzing and breaking the restrictions of the formation here, he was also paying close attention to the movements outside.

Lin Zheyu was not naive enough to think that he was the only one who could explore into this black abyss.

He had just entered the Nightmare City Wonderland, and in less than ten years, he had adapted to the concentration of nightmare power in the Black Abyss.

There must be quite a few powerful people who entered this wonder earlier than Lin Zheyu and were able to withstand the erosion of the nightmare power in the black abyss.

However, Lin Zheyu was not too worried.

The nightmare power in the Black Abyss is extremely strong, and fighting here is not a wise choice.

Those guys won't act rashly unless they see treasures or opportunities of sufficient value.

Puff puff! ! !
Lin Zheyu kept pointing his fingers, and endless martial arts divine patterns turned into blood-red mist, which continuously penetrated into the nearby void.

Time passes slowly...

More than a month later, Lin Zheyu shook his head and felt that his condition was rapidly deteriorating.

This is caused by excessive erosion by the power of nightmare.

He kept attacking continuously, constantly analyzing and breaking the formation restrictions here, which caused the nightmare power to erode him more severely.

After just over a month, he felt like he couldn't hold on any longer.

huh~~~
Lin Zheyu let out a sigh of relief and didn't dare to stay here any longer.

Four clones walked out of his body and sat cross-legged at different true eyes, respectively, to maintain the formation restrictions that he had finally controlled on behalf of the original body.

The formation restrictions here are extremely powerful and have the ability to self-repair.

Although it was extremely slow, it was able to heal itself thanks to its self-repairing ability and the erosion of the extremely strong nightmare force.

After Lin Zheyu left, without his support, the results that had been achieved with great difficulty would be lost.

……

"He left..."

The purple-clothed woman glanced at Lin Zheyu's departing back and looked at her senior brother with a smile.

"Don't be impatient, wait for other Taoist friends to take action first."

"There may be something extraordinary hidden here, but it is not easy to break the formation restriction 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 maintain herself in such a strong nightmare environment without falling into a dream.

“If we don’t take any action, it will be no problem to maintain it for three months.” said the woman in purple.

"Three months... is a bit short..."

The man in gray shook his head and said, "Let's go out first."

"Come back after you refine the nightmare power in your body and improve yourself to the best condition."

"it is good!"

The woman in purple nodded.

The two of them controlled the formation flags, which surrounded them, and under the cover of the formation flags, they quietly rushed towards the outside of the Black Abyss.

……

"It's Chang Zichen and Mu Yunshi, they are here too..."

In the darkness, a pair of scarlet eyes suddenly opened and looked in the direction where the man in gray and the woman in purple had just left.

"They hid so well that I couldn't even find them just now." another voice came.

"What is this place? Is there any relevant record in your clan's books?"

The strong man of the Flame Demon Clan looked aside and asked calmly.

This is a humanoid creature with a completely red body, engraved with complex and mysterious patterns, six arms, and a ferocious red eye between its eyebrows.

"No, there are few records about Nightmare City in our clan, let alone this mysterious abyss."

The strong man hidden in the gray mist said lightly.

The fog surged, revealing the other party's blurry figure.

It was a huge creature, pitch black, with a pair of wings on its back, and looked like a wolfhound.

This is a strong man from the Tianlang tribe.

The Sirius Clan is also one of the most powerful clans in the Xuanhai Region.

"Then wait a little longer."

"Once that human breaks the formation restriction here, you will know." The strong man of the Flame Demon Clan said lightly.

"The formation here is quite strong, but it is not so easy to break. It is still unknown whether that person can succeed."

"You stay here and I'll continue to search deeper. Maybe I can find something else."

The strong man from the Sirius clan said this lightly, his figure swayed slightly, and he disappeared in an instant.

The powerful Flame Demon Clan glanced at him.

He pondered for a moment, moved slightly, and rushed out of the abyss.

The powerful Flame Demon has been here for a long time, and he also needs to leave for a while to refine the nightmare power that has eroded into his body.

The powerful member of the Flame Demon Clan had originally planned to leave, but when he was on his way out, he sensed the movement here, so he quietly lurked over to observe the situation here.

However, as the strong man of the Tianlang tribe said, he observed that the formation restrictions here were indeed powerful and extremely difficult to break.

That human cultivator may not be able to break it.

He observed secretly for a long time, but did not find any treasures or opportunities hidden in this formation restriction.

Therefore, there is not much point in continuing to stay here.

However, before leaving, his mind moved slightly, and hot liquid like magma oozed out of his body.

This ball of hot liquid surged, turned into a clone, and disappeared into the mist.

……

Soon, a month passed.

Lin Zheyu refined the nightmare power that had eroded into his body and returned to the black abyss.

"Have everyone left?"

Lin Zheyu looked around and was a little surprised.

Before leaving, there were several strong men hiding in the dark nearby, but I didn't expect that they all left after I came back.

According to the memories fed back by the clone, during the time he was away, several strong men tried to break through the formation restriction.

But all failed.

The formation restrictions here are extremely powerful and cannot be broken by force.

Unbridled bursts of powerful force will accelerate the erosion of the nightmare force on oneself.

If you want to pass through this powerful formation restriction area, you need to have a certain level of attainment in formation restrictions.

And obviously, those strong men before didn't seem to be very good at this.

"Oh, no, there is a little mouse hiding there, and it is hiding really deep."

Lin Zheyu's expression suddenly changed and a sneer appeared at the corner of his mouth.

His figure moved slightly and disappeared in an instant.

boom!
In the dark void, a blinding fire suddenly erupted, and a body covered in flames shot out and rushed towards the depths of the abyss.

"Want to run?"

"Leave me alone!"

A flash of coldness flashed across Lin Zheyu's eyes.

I thought that just a clone could hide in the dark and monitor what was going on here.

This is too much of an underestimation of him.

Boom!

Lin Zheyu suddenly appeared behind the clone of the powerful Flame Demon Clan and punched out fiercely.

Unparalleled power exploded, instantly destroying the clone of the Flame Demon.

"The Flame Demon Clan..."

Lin Zheyu was holding a fist-sized, hot stone in his hand. It was left behind by the demise of the powerful Fire Demon.

It is the other person's heart core.

After putting away the heart core, Lin Zheyu carefully explored the nearby void again to make sure that there were no other guys hiding in the dark.

Then, he moved slightly and continued the unfinished task.

More than ten days later.

A vague wave came from a distance.

The gray-clothed man Chang Zichen and the purple-clothed woman Mu Yunshi who had left earlier also came back.

The two were shrouded in the formation flags, and no aura emanated from them.

“Those guys are gone.”

Mu Yunshi looked around and said with some surprise.

"They tried to break the formation, but they gave up because they knew it was too difficult. The formation restrictions in this area are not that easy to break."

Chang Zichen looked around and said with a smile, his eyes showing confidence and pride.

"If they knew what was hidden inside, they would probably regret giving up so quickly!"

The purple-clothed woman Mu Yunshi said with a smile.

After the two left, while they were recovering and refining the power of nightmare outside the Nightmare City, they finally figured out where this place was.

There are relevant records in the sect they belong to.

More than 10 million years ago, there was a brilliant genius who once entered this abyss and discovered this area covered with powerful formations and restrictions.

"Yes, this is most likely the location recorded in the classics."

Chang Zichen looked around carefully again and confirmed his guess.

"The formation restrictions in this area have a powerful concealing effect. No wonder we didn't find this place when we passed by it before." Chang Zichen said.

One of their purposes of entering this black abyss was to find the area recorded in the classics.

Unfortunately, Chang Zichen and Mu Yunshi searched for a long time but couldn’t 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 conduct a thorough search that he accidentally triggered the formation restrictions here.

When Lin Zheyu's clone passed by, he was unable to sense anything unusual in the area.

Until his clone accidentally stepped into the area covered by the formation restriction and was forced to self-destruct.

Lin Zheyu just discovered the abnormality here.

Afterwards, he sent out more than a dozen clones in succession, and without exception, they were all killed here.

"Senior Brother, should we go in?" Mu Yunshi asked.

"Wait!"

Chang Zichen smiled slightly.

"The formation restriction in this area is not so easy to break, otherwise the senior would not have returned empty-handed."

"Let's ask the fellow Taoist in front of us to explore the way for us first."

"We'll take action after he fails." Chang Zichen said with a smile.

"What if he succeeds?" Mu Yunshi asked.

"Wouldn't it be better if it succeeded?"

Chang Zichen smiled meaningfully: "If it succeeds, we just need to wait here and wait for him to come out."

"Well, let's start the preparations!" Mu Yunshi said with a smile.

……

"Cave?"

Lin Zheyu looked ahead, feeling a little surprised.

As he continued to analyze and crack the restrictions of the formation, Lin Zheyu finally saw the scene in the central area of ​​the formation.

What appeared before my eyes was an ordinary cave on the cliff.

"Could it be that this is the place where a powerful Nightmare Clan member once went into seclusion?"

Lin Zheyu's eyes moved slightly, and he couldn't help but guess.

If this is really the retreat place of a powerful Nightmare Clan member, then perhaps one can find the Nightmare Clan's skills inside.

This place is the original ancestral land of the Nightmare Clan. Anyone who can meditate 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.

One can imagine how powerful the complete formation restriction is.

The person who was in seclusion inside at the time was very likely a world master or even a stronger person!
"call……"

Lin Zheyu exhaled lightly, and a solemn look gradually emerged in his eyes.

Although this is just a remnant scene, no one can guarantee that the powerful people who were in seclusion there at the time will not have residual images projected out from the long river of time.

If this is really the retreat place of a powerful person in the Third Era...

"continue!"

Lin Zheyu did not hesitate at all and continued to try to break the formation restrictions here.

In any case, we have to go inside and take a look first.

Since this is a wonder at the spiritual transformation level, the danger that may arise here will not be too beyond the scope.

Even if there really is a powerful being from the Third Age who was projected out from the long river of time, Lin Zheyu would have to fight him first!
Boom!

Taking a step forward with his right foot, Lin Zheyu punched fiercely into the void in front of him.

At this point, the power of the formation restriction became even stronger. It was no longer possible to poke the key node where the formation restriction intersected with just one finger.

……
