The huge Xuanwu spewed out a dragon-like demonic qi, making the space where Lin Feng was located seem to be constantly expanding and contracting.

If it weren't for Lin Feng descending from the Heavenly Domain, such a scene would have been extremely shocking. Of course, even so, Lin Feng at this moment was full of shock.

Because in his opinion, if this Xuanwu was located in the Heavenly Domain, it must have grown to an extremely terrifying level after such a long time.

The old man looked at the shocked Lin Feng, and a cold smile flashed in his eyes.

But at this moment, Lin Feng suddenly looked at him, and then slapped his palm at him without hesitation.

Suddenly, a hurricane roared out, and I saw a fist full of rich blood roaring directly towards the old man.

The old man frowned, and then waved his big hand.

rumble

With a muffled sound, Lin Feng's fist was directly slapped away.

Lin Feng didn't have any surprises about this, although he didn't do his best to make a move, he also tested the horror of this old man.

"What did you bring me here for?" Lin Feng looked at the old man and asked lightly.

The old man chuckled, "You are a clever little fellow, you have something on you, if you are willing to give it to me, maybe I can let you get out of here safe and sound." ”

The old man's words made Lin Feng's eyes stare involuntarily.

"What's that?"

"Before the crow died, he wanted to give you the key to open the Imperial Palace, and with your combat strength, it is not easy to open the Imperial Palace. Give me the key and I'll let you go. The old man looked at Lin Feng and said lightly.

Lin Feng didn't speak, but other thoughts appeared in his heart.

Lin Feng had doubts about that key, but what he didn't expect was actually the key to open the Imperial Palace.

The Imperial Palace is the core place of this Demon Heaven Emperor City, and it is also the most difficult place for the Demon Heaven Emperor City to set foot in this way, but that Emperor Palace is the place with this most terrifying opportunity in this Demon Heaven Emperor City, if he can enter the Imperial Palace, maybe Lin Feng can step into the early stage of life and death faster.

But now Lin Feng knew that if he didn't hand over the key, the old man would definitely not let him leave.

If Lin Feng had the combat power to compete with the old man, he would not be so passive in the future.

However, Lin Feng's strength at this time is in front of this old man, it is estimated that there is no possibility of resistance at all, you must know that there is not only the old man's guard here, but also a Xuanwu that Lin Feng can't see through the realm.

Even if this Xuanwu gave Lin Feng a feeling of lifelessness, once this Xuanwu was powerful, it was estimated that there were not many creatures in this Demon Heaven Emperor City who were his opponents, even the creatures left behind in the Demon Heaven Emperor City!

After thinking for about ten seconds, Lin Feng gritted his teeth and appeared in his hand with the slap laughing, quaint key.

As soon as he saw the key, two thick smiles burst into the old man's eyes.

"Give me the key, and I'll give you a chance to leave alive. The old man grinned.

Lin Feng said in a deep voice: "If I give it to you now, I don't think you will let me go easily, only if you let me go first, I can give you the key, otherwise, I will destroy this key immediately." ”

Lin Feng's words made the old man look at him with disdain.

"The cultivation at the peak of the Three Spirit Realms, if you can destroy the key to open the Imperial Palace, I don't dare to lead you here. The old man said lightly.

Lin Feng frowned.

The key was cut from a very rare jade, and it was tempered by powerful monks.

With Lin Feng's current strength, it would be very difficult, difficult, or even impossible to destroy that key.

However, Lin Feng still gave it a try.

The source of black erosion surged, and suddenly a terrifying corrosive power emanated from Lin Feng's body, and then he saw that Lin Feng's other palm was rapidly covered with a black source of black erosion.

This source of black erosion was not yet able to exert its full power with the current power of the forest wind.

If Lin Feng could activate ten percent of the power of the Black Eclipse Source, he could destroy it in an instant compared to the key in his hand.

"Corrosive power!" After the old man felt the breath, his eyes couldn't help but condense slightly, and he looked at Lin Feng with a little surprise.

"Are you surprised?" Seeing this, Lin Feng gritted his teeth and snorted coldly.

The old man took a deep breath, then waved his big hand, and suddenly a majestic force roared out.

Lin Feng's eyes froze, and the aura around him instantly rioted, instantly condensing into a huge defensive shield in front of him.

However, after a muffled sound, the defensive shield around Lin Feng was directly exploded by the old man's attack, and then directly blasted Lin Feng dozens of meters away.

Burst!

Lin Feng fell to the ground, a mouthful of blood spurted out, and his face was slightly pale and he looked at the old man with a thick look of disdain in his eyes.

For this old man, he glanced at Lin Feng lightly and said: "It's not that I don't kill you, but I'm too lazy to kill you, if you continue to don't know what to do, I will be angry, once I am angry, even if you give me the key immediately, I will kill you." ”

Lin Feng wiped the blood from the corner of his mouth and slowly got up and stood up.

He glanced at Xuanwu in the distance, and then his gaze fell on the old man.

"Let me out, I'll give you the key. Lin Feng said in a deep voice.

After finishing speaking, he put the key in his hand into a space ring and continued: "I can destroy this space ring immediately, and then everything in the space ring will rush into the barren land. ”

The old man's eyes froze slightly, obviously Lin Feng's approach made him really angry.

But for the anger of the old man, Lin Feng didn't seem to see it, because he felt that now he wanted to leave alive, this was the only way!

"Kill him!"

Regarding Lin Feng's threat, the old man's eyes narrowed for a moment, and then he snorted coldly at that Xuanwu.

Xuanwu didn't speak, but slowly walked towards Lin Feng.

With Xuanwu's arrival, an aura that made Lin Feng extremely uneasy emanated from this Xuanwu's body.

Lin Feng kept retreating.

But just as Xuanwu wanted to make a move on him, an extremely terrifying wave suddenly emanated from the middle of the five mountains in the distance.

This scene made the old man tremble slightly, and Xuanwu is eyes showed a hint of clarity.

"Get out!"

An indifferent voice suddenly resounded throughout the space, making Xuanwu feel as if he had been bombarded by a huge hammer, directly blasting Xuanwu hundreds of meters away.

As for the old man, he snorted, and a wisp of blood overflowed from the corner of his mouth.

The next moment, the old man looked at the five mountains with great fear.

This scene made Lin Feng slightly stunned.

He turned his head to look at the five mountains in confusion, and the angry shout just now gave Lin Feng an extremely familiar feeling.

"Dad, is that you?"

Lin Feng took a deep breath and muttered.

These words made the face of the old man not far away change slightly.

Immediately, he bowed slightly to the five mountains, and then his body quickly exuded a thick demonic aura, and then under Lin Feng's gaze, he quickly disappeared from this space.

As for the earth smashed in the distance, Xuanwu stretched his neck at this moment, and a wisp of blood red appeared in his eyes.

However, after he glanced at the five mountains, he hurriedly rushed into the distance.

The sudden silence made Lin Feng a little uncomfortable.

He looked at the five mountains in the distance suspiciously, and then glanced at the surroundings.

In the end, he thought about it for a while, and then did not go in the direction of the old man's departure.

Lin Feng didn't know how to get out of here, but he believed that he could get out of here.

The dark world was a little different from the outside, and the entire space was filled with a bleak demonic aura, and monks who were not demon cultivators couldn't survive here at all. But Lin Feng is different from ordinary people, as long as it is energy, he can use it to strengthen himself.

A valley in the distance attracts the forest breeze towards the five mountains.

There are hundreds of black flowers in this valley, and these black flowers are extremely bewitching, and there are wisps of black and golden light on them. This made Lin Feng extremely curious.

He didn't know the flower, but what he did know was that it was definitely not easy to grow a flower here.

Lin Feng was also very curious about this space, but he knew that this space was definitely not a safe place, and now he had to find a way to get out of here quickly.

Once the old man goes and returns, and forcibly attacks him, then he may be in danger.

He still remembered what the old man had said earlier, that is, if he wanted to leave here, he needed to climb to the top of the five mountains and tear open the barrier before he could leave.

But Lin Feng knew that he absolutely couldn't believe this, but he couldn't go in the direction of the old man's departure, because in that case, it would be like a sheep in the tiger's mouth.

Time passed minute by minute, and Lin Feng didn't know how big this enchantment was, but he went around a large area, and still didn't find anything.

But just when Lin Feng was restless, he heard the sound of the torrent as soon as he came in.

Lin Feng turned abruptly and looked in the direction where the sound of the torrent came from.

Immediately, Lin Feng was overjoyed, and quickly walked in the direction where the sound of the torrent came from.

Soon Lin Feng saw a wide river, which flowed from south to north, but what puzzled Lin Feng was that he didn't feel the fluctuation of the water.

It was obviously a big river in front of him, but Lin Feng found that the water in this river didn't seem to be water!

"What's going on?" Lin Feng couldn't help but be taken aback, and looked at the big river in front of him suspiciously.

But just as Lin Feng wanted to go to the river and touch the so-called river water in person, an extremely desolate aura surged out from the big river, and quickly roared in all directions. Lin Feng was slightly startled. But what surprised Lin Feng even more was that the big river in front of him suddenly disappeared after that fluctuation appeared, leaving behind a huge riverbed.

This scene made Lin Feng stunned on the spot.

"The power of time!" Lin Feng thought of something for a while, and after thinking of something for a while, a thick look of surprise appeared in his eyes, and he couldn't help but whisper.

There used to be a large river here, but now only a riverbed remains. What Lin Feng saw just now was just an image left by the former big river, not the real big river!

Lin Feng took a deep breath and hurriedly looked back at the five mountains.

What made Lin Feng feel at ease was that the five mountains were still there, but the scenery around these five mountains had become different from before.

Lin Feng had a feeling that these five mountains seemed to be going through a catastrophe that he could hardly feel, because he saw that fine cracks appeared on the top of those five mountains.

"Could it be that this enchantment has interfered with the flow of time here after I appeared?" Lin Feng muttered to himself in confusion.

Click

The abrupt crisp sound made Lin Feng tremble violently.

Then he saw that the cracks on the five mountains were getting bigger and bigger, and they were getting bigger and bigger!

Lin Feng took a deep breath, his face became not very good-looking, if there was chaos in the time here with his arrival, then he would be extremely dangerous here, maybe he would be wiped out by the chaotic time, because Lin Feng had not seen the existence of the ability to fight against time so far.

At this moment, Lin Feng's face became more and more ugly.

But at this moment, a piano sound that made Lin Feng shake all over his body suddenly resounded throughout the entire enchantment.

When Lin Feng turned his head to look in the direction where the sound of the piano came from, a black shadow seemed to break through the limitations of time and appeared in front of him.

When he saw the person in front of him, Lin Feng was slightly stunned.

"Mother!"

Lin Feng subconsciously screamed.

At this time, it was Dugu Yeqi who appeared in front of Lin Feng.

At this moment, Dugu Ye's black clothes give people an extremely capable feeling, with long hair tied up, white skin and a face with a hint of vicissitudes, which makes it easy for people to have a sign of trance.

"Why are you here?" Dugu Yeqian asked very suspiciously as he looked at Lin Feng in front of him.

Lin Feng told Dugu Yeqi about being attracted here by the old man.

After listening to Lin Feng's words, Dugu Yeqi took a deep breath and said in a deep voice: "The guardians of the Four Holy Palaces are not qualified to step into the realm of the five mountains, I think it is the existence of the five mountains that has escaped. But since he escaped, he must have relied on his own ability, but if he wants to beat you, it's just damned. ”

Looking at the angry look on Dugu Yeyan's face, Lin Feng's heart was very warm.

In this world, presumably only true relatives can truly shelter you from the wind and rain.

"Let's go, I'll take you away, this Five Mountains Realm is about to collapse, and some of the existence under the Five Mountains may not be long before they rush out of the Five Mountains, and then the entire Mortal Realm will fall into chaos again. However, this is not a bad thing, after all, the people of the Heavenly Domain want the origin of the earth of the Mortal Domain, and after the existence of these hatred of the Heavenly Domain, it is estimated that the people of the Heavenly Domain will die a lot. Dugu Yeqi's eyes narrowed slightly, and he muttered to himself lightly.

These words made Lin Feng very puzzled.

But just when he wanted to ask clearly, Dugu Yeqi grabbed his palm, and then went directly through the air.

The direction is the direction in which the old man left.

Lin Feng wanted to tell his mother, but he pressed it, he wanted to see how strong his mother was, after all, since he and Dugu Yeqi met again, he hadn't seen his mother really make a move. In Lin Feng's impression, his mother was a powerless person.

But now Lin Feng felt that his mother was unusually terrifying, and even made him a little unexpected.

Click

Just after Lin Feng was taken away from the five mountains by Dugu Yeqi. The Heavenly Demon Guqin appeared in Dugu Yeqi's hands.

This scene made Lin Feng extremely puzzled.

"You see, what is the real sound. Dugu Yeqian sat cross-legged, put the Heavenly Demon Guqin on his legs, and then whispered lightly.

Lin Feng didn't speak.

But in the next moment, Lin Feng was suddenly startled.

I saw that the Demon Guqin trembled violently that day, a pitch-black string suddenly trembled, and suddenly a sound that made Lin Feng tremble, and then Lin Feng was shocked to see the speed of the cracking of the five mountains in the distance suddenly accelerated.

The sound of the piano kept ringing, like a heavenly knife, constantly moving towards the distance.

When the five mountains collapsed suddenly, the entire barrier was directly shattered.

Lin Feng suddenly found himself reappearing in the inner sanctum of the Raven Palace.

But what puzzled Lin Feng was that his mother Dugu Yeqi did not appear.

But the sound of the harp resounded abruptly throughout the inner sanctum.

Except for Lin Feng in the direct inner hall, all the other living beings suddenly let out a terrible scream, and soon Lin Feng saw that many monks were bleeding from their seven orifices, and their eyes fell in a pool of blood.

"Nine Heavens Demon Sound, cultivated to the extreme, a single note can explode a planet. Dugu Yeqi's voice suddenly sounded in Lin Feng's ears.

Lin Feng was stunned.

"Remember, this Heavenly Demon Guqin is a treasure that your father refined for your sister, and after this matter is over, give this Heavenly Demon Guqin to Xiaoyu, I believe that Xiaoyu will definitely reproduce the true power of the Heavenly Demon Guqin. Dugu's voice sounded again.

Lin Feng's expression froze slightly.

When he came to his senses, a guqin with a length of one meter and a half and a width of fifty centimeters appeared in front of him.

The Heavenly Demon Guqin is rumored to be the natal weapon of the Demon Lord of the Demon Heaven Empire.

But now Dugu Yeqi told Lin Feng that this Heavenly Demon Guqin was an artifact refined by Lin Batian for Lin Xiaoyou. This made Lin Feng a little difficult to accept for a while. Because Lin Feng's mind is too chaotic and chaotic now, the chaotic Lin Feng has no clue.

Regarding his father's identity and his mother's mystery, Lin Feng has too many doubts.

However, except for the Heavenly Demon Guqin, Dugu Yeqi did not appear, and as for where he went, Lin Feng didn't know at all.

He looked at the guqin in front of him, and there was a deep doubt in his eyes. However, Lin Feng soon included the Heavenly Demon Guqin into his ghost. Of course, Lin Feng at this time didn't know where Lin Xiaoyu was taken by the big snake.

Big Snake, Mr. Hao, and Lin Xiaoyu were the first creatures to step into this Demon Heaven Emperor City.

But several days passed, and Lin Feng never saw these three people again.

The pungent smell of blood made Lin Feng hurriedly turn around.

At this moment, there is not a single living creature in the inner hall except for Lin Feng!

After about ten seconds, Lin Feng shook his head and looked at the other stone door in the inner hall, he walked over slowly, then took a deep breath, let out a low roar, and pressed his hands on the stone door!
