The Eastern Regions, the Taixuan Immortal Mountain, which used to be a holy place for cultivation, no longer exists, this is no longer a land of immortals, thousands of miles of area, all under the shroud of demonic energy.

Taixuan Mountain, with nine spiritual peaks, represents the inheritance of the nine veins of Taixuan.

But now, in the original location of the Taixuan Nine Peaks, the earth has sunk in, forming a bottomless demon cave that seems to connect this demon world.

The demonic aura of the demon cave is swirling, it is the source of the demonic qi in a radius of thousands of miles, and from time to time there are several terrible and terrifying demon roars coming out of the demon cave.

A demonic force that can disturb the mind swirls between heaven and earth, and all the creatures in the vicinity have been demonized into terrifying monsters by this demonic power.

From time to time, you can see demonized goshawks, skimming from the sky, two-headed demon tigers looming in the forest, and even the vegetation is stained with a trace of demonic energy.

At noon, the figures of Gu Fei and the others appeared near this demon cave, and they did not enter the range shrouded in demonic qi, but just watched from the periphery.

"It's the breath of a true demon!" When Hei Tian saw this demon cave, he was immediately moved, a true demon was born, no wonder the masters of the three major sects and the major sects came to attack this demon cave, and almost ended up with a total annihilation.

Although it was noon, the sun was shining, but the area ahead was still dark and terrifying, and it seemed that even the sunlight could not penetrate the magic clouds that shrouded the sky over that area.

At this time, suddenly a demon eagle walking through the demon clouds noticed Gu Fei and them, and then silently approached Gu Fei and them, and the demon eagle seemed to regard Gu Fei and them as his prey.

"Huh!"

The demon eagle came closer, and then suddenly turned into a black shadow, and flew towards the black sky to the extreme, and a tragic evil aura swept out.

This demon eagle seemed to have slaughtered a lot of living beings, and the weight of the evil aura exuded from its body made Gu Fei and the others change color.

"I don't know if I'm alive or dead!" Heitian's eyes shot out two rays of divine light and pierced forward.

"Poof!" Hungry, the head of the demon eagle immediately exploded, and the corpse of the demon eagle fell from the sky, blood splattered.

Gu Fei noticed that the blood that sprayed from the neck of the demon eagle was not bright red, but black, as black as ink.

This is demon blood, those demon blood drip to the ground, and the stones are corroded by demon blood into small black holes, emitting wisps of black smoke.

"It's a completely demonized creature!" said Kuroten, who seemed to know a lot about monsters.

Just as the eagle's body fell to the ground, a demonized wolf sprang out of the bushes, snatched the eagle's corpse in one gulp, and ran into the bushes.

Seeing this scene, everyone couldn't help but glance at each other, this demon cave is definitely a terrifying Jedi, a normal creature, and there will be no zài nearby at all.

Even if the monk stays here for a long time, I am afraid that he will be tempted by the invisible demonic nature that surrounds the void, and he is in danger of falling into the demon.

"You guys wait for me outside, I'll go in and have a look!" In the end, Gu Fei decided to go in and take a look.

"Big brother, let's retreat first!" Xiao Qing felt uneasy, it seemed that there was a terrifying ancient demon lurking in the demon cave, and the demonic nature here made his heart palpitate.

Gu Fei shook his head, and then said: "Since you have come here, it's a pity not to explore, you don't have to worry, if you encounter danger, it's a big deal to hide in the inner heaven and earth, or in the hell road." ”

Xiaoqing remembered that Gu Fei did have a lot of means to save his life, not only controlling the two inner heavens and earths, but also freely entering and exiting the Hell Dao, I am afraid that even if the great power comes, he can also escape under the powerful hands.

What Gu Fei decided, he would not change lightly, and he stepped into the demonic land in front of him.

Xiaoqing and the others didn't stop Gu Fei anymore, they didn't go in, they waited outside, they agreed with Gu Fei that if Gu Fei didn't come out of it within twelve hours, they would go to Taixuanmen to wait first.

Taixuanmen, completely declined, became a second-rate sect in the Eastern Regions, the famous mountains and rivers are occupied by other great religions, and the place where Taixuanmen is now located is a place called Dragon Valley in the mountains thousands of miles away.

There is a spiritual vein under the Dragon Valley, of course, this is not a high-grade spiritual vein, not even a dragon vein, of course the major sects do not look down on such an inferior spiritual vein.

As a result, Taixuanmen temporarily settled down in Dragon Valley, and lived for two hundred years, and the disciples of Taixuanmen rarely walked out of Dragon Valley, and gradually disappeared from everyone's sight.

From the infinite scenery to the complete decline, no one cares, the changes of Taixuanmen can be said to be too big, the rise and fall of a hundred years!

The decline of a great sect so quickly is not unique in the cultivation world, but it can be regarded as rare.

Of course, compared to the Great Yan Dynasty's Great Sect Ziwei Sect, Taixuanmen was already considered lucky, after the powerhouses of the Ziwei Sect's four immortal god realms were destroyed by Xiaoqing and them, the Southern Yan Great Sect Ziwei Sect was quickly divided by other forces.

Taixuanmen still has a chance to rise again, but Ziwei Sect has none.

The Demon Cave is hundreds of miles in circumference, and dry bones can be seen everywhere walking among the rocks, among the grass, and the soil is red, as if it has been soaked in blood.

Gu Fei cautiously walked through the mountains and lurked in the direction of the Demon Cave.

There were still a few demon eagles hovering in the sky, Gu Fei gathered the breath on his body, and the power of inner heaven and earth overflowed from the dantian, enveloping his body and isolating a breath on his body.

"Roar!"

A monstrous demonic beast like a hill walked in front of him, and Gu Fei hid behind a boulder, waiting for the demonic beast to pass before continuing to move forward.

The closer he got to the demon cave, the stronger the demonic power became, and the monsters that Gu Fei encountered became more and more powerful, and Gu Fei did not alarm any monsters.

When I arrived near the Demon Cave, the demonic beasts that infested around the Demon Cave were extremely powerful and hideous, and some of the bones scattered on the ground were crystal clear, definitely not mortal bones.

"Roar!"

A demon tiger with two heads is roaring, this demon tiger is enjoying a big meal, but another demon wolf with wings on its back is the prey of the demon tiger and is pressing towards the demon tiger.

The demonic beasts near the demon cave are extremely powerful, and the demon tigers and demon wolves are all angry, and their roars shake the mountains and forests.

Gu Fei lurked aside, sensing the movement around him, it seemed that there was no demon in the entire demon land, only demonized demonic beasts were moving around.

"How can it be so quiet?" Gu Fei thought to himself.

Listen to the old man who guarded the formation, this battle was earth-shattering back then, and the three major sects and the major sects in the Eastern Regions were almost wiped out, and there should be a demon who has a stake here!

"Roar!"

"Roar!"

At this time, the two demonic beasts finally fought, and one side of the mountain and forest shook, startling other demonic beasts to flee for their lives in the distance, and only some powerful demonic beasts were watching.

Gu Fei took advantage of the fact that the attention of all the demonic beasts was attracted to the past, and he stepped on the eight desolate steps, turned into a phantom, and rushed into the demon cave.
