The Void Energy rippled and a vortex appeared. Ye Feng walked out from inside and landed on the ground.

As far as the eye could see, this was an incomparably vast space, with no end in sight.

Tens of thousands of mountains stretched, the rocks were craggy, tens of thousands of ancient trees were old, and in the middle of these ten thousand mountains were countless tattered pavilions.

The entire space was dark and lifeless!

This was Sky Cavern Mystic Realm!

Bang bang.

Suddenly, a series of low sonic booms sounded out from not too far away.

Ye Feng looked towards the source of the sound and saw two or three strange red-skinned ape jumping out from the ruins of the building, while letting out strange fierce cries.

It was not hard to tell that there was a battle between Martial Cultivator and the Fire Demons.

"Fire Devil!" Ye Feng's gaze darkened, and his Phantom Step stepped out.

Sure enough, there were three Fire Demons surrounding Du Rufei and the others, causing Ye Feng to feel surprised.

After entering the Sky Cavern Mystic Realm, he never thought that he would meet Du Rufei and Lin Xueer so quickly.

Du Rufei and Lin Xueer found it difficult to face the three fire devils whose strengths were around their First Level of Martial Master.

Especially Lin Xueer with her Ninth Level of Martial Disciple; when she was attacked by the two fire devils, she was unable to control her strength, "Brother Fei, help me quickly!"

However, when Du Rufei was entangled with a fire demon, although he did not feel much pressure, he could not free himself from helping Lin Xueer. Gritting his teeth, he said: "I have difficulty protecting myself, you think of a way yourself!"

Ye Feng shook his head, the Phantom Step rushed forward, closing in on a flame demon, and struck it on the head.

The Fire Demon seemed to have sensed danger and turned around to look at Ye Feng with a pair of red eyes.

Bang.

As though Ye Feng had smacked this fire devil on the head with his palm, it died on the spot.

Lin Xueer heaved a sigh of relief, but upon seeing that it was Ye Feng, she had a complicated look in her eyes.

Ye Feng made his move again, and with a single punch, he killed a fire demon.

Du Rufei on the other hand, seemed to have received a shock, as though he had been injected with chicken blood. His attacks were extremely berserk, and in a moment, he had killed the fire demon.

Only, in the face of the two of them, Ye Feng had nothing to say.

Lin Xueer gritted her teeth: "Ye Feng, even if you help me, I won't be grateful to you!"

Ye Feng didn't want to bicker with this kind of small-minded and vicious woman, so he kindly suggested: "If you don't want to die, follow me."

"Humph!" Lin Xueer snorted, and said disdainfully, "Following you? What a joke! Brother Fei and I can still take a mere Fire Demon, so there's no need for you to pretend. "

"Idiot!" Ye Feng shook his head. He muttered to himself for a while, then turned and left.

Fire Devil Race naturally could not bring danger to the two of them. Even if they could not beat him, they could still escape. However, Ye Feng was not worried about the Fire Devil Race, but rather the two third stage s. If they were to be targeted by these two Black Man, it would be hard for Du Rufei and Lin Xueer to escape death.

Unexpectedly, Lin Xueer didn't appreciate her kindness and still looked down on her. Ye Feng couldn't be bothered to care about her either.

Looking at Ye Feng's departing figure, Lin Xueer's eyes flashed with a cold light: "Brother Fei, should we cripple him too?"

"Forget it, neither of us is his match!" Du Rufei sighed, then turned and walked to the other side.

"Brother Fei!" Lin Xueer was not satisfied, she bellowed and could only follow along.

Ye Feng ran towards an ancient forest alone. His goal was clear, he was looking for Heavenly And Earthly Treasures s to kill Fire Demons.

As soon as he entered the ancient forest, a fearsome fire demon came out of nowhere with a ferocious look on its face.

"You're courting death!" Ye Feng's gaze turned cold. Facing it head-on, he killed it with a single punch.

This fire devil only had the strength of Ninth Level of Martial Disciple, naturally, it couldn't take Ye Feng's all-out attack.

After searching for a while in the ancient forest and not finding any Heavenly And Earthly Treasures, he met another three Fire Demons who didn't know the depth of the heavens and the earth.

Ye Feng killed them all.

Actually, tens of thousands of years ago, the power of the fire devils in the Sky Cavern Mystic Realm was extremely terrifying. When they came out of the Sky Cavern Mystic Realm, they harmed humans.

Human super Martial Cultivator had formed an organization to strangle Fire Devil Race.

So far, his Fire Devil Race had been almost completely exterminated, and he was facing annihilation.

A few weak Fire Demons had hidden themselves into the Sky Cavern Mystic Realm. Every time the Sky Cavern Mystic Realm opened, they would occasionally come out to eat people.

Therefore, Nine Sects had made an agreement that whenever Sky Cavern Mystic Realm opened, disciples would be sent to hunt them.

This tradition has continued for more than five hundred years.

Therefore, Ye Feng did not encounter many fire devils and their strengths were not high either.

As for whether or not there was still a powerful fire devil hidden within the Sky Cavern Mystic Realm, no one knew.

This was because, in these hundred years, no Martial Cultivator had encountered any strong Fire Demons.

Time quickly passed and in the blink of an eye, an entire day had passed.

On this day, a white-robed youth appeared in the ruins of a building. His handsome face revealed traces of helplessness.

This youth was Ye Feng.

In this past month, he had been to many places, and other than killing a dozen or so Fire Demons that did not know the thickness of the sky and earth, there was no news of the Heavenly And Earthly Treasures.

Sky Cavern Mystic Realm was still five months away from forcefully sealing. If the Human Martial Cultivator inside didn't escape in time, they would die!

Shaking his head, Ye Feng flew towards the mountain range ahead.

Suddenly, two corpses lay on the ground in front of him.

"Raindrop Door!" Ye Feng recognized the two corpses as disciples of Raindrop Door.

The Space Ring s on the two corpses had disappeared.

Ye Feng's expression became heavy. This was not the first time he had discovered a corpse, and ten days ago, he had already seen the corpse of a Snowfall Gate disciple.

This was obviously killing someone for their treasure.

Ye Feng guessed that those two Black Man s were the killers.

Who knew how many Young Fighters had already been viciously harmed by them?

Bang.

At this moment, a faint sonic boom came from the ancient forest far ahead.

Ye Feng frowned, after pondering for a moment, he stepped out of the Phantom Step and flew over.

Blood trickled down the corners of Du Rufei's and Lin Xueer's mouths as they fell to the ground with terrified expressions.

In front of them were two Black Man s.

"Hand over the Space Ring!" A tall and skinny Black Man said coldly.

Lin Xueer said in fear: "Brothers, our Space Ring has already been stolen! Please let us go. "

The other short Black Man said coldly, "If you don't have any treasures, you can go and die!"

Lin Xueer was terrified, kneeling down and begging for mercy: "Brothers, don't kill me, I'll do anything you ask me to, don't kill me."

Du Rufei said: "Lin Xueer, if we do not require them, they will not let us go. We will fight with them!"

Lin Xueer laughed sinisterly: "Du Rufei, if you want to die, I don't want to die. If you want to die, go and die."

After saying that, she quickly begged the two Black Man s for mercy, "Brothers, I'll do whatever you want me to do, don't kill me!"

"Tsk tsk!" The short Black Man laughed strangely, and looked at Lin Xueer with an unkind gaze. He paid special attention to the most important part of Lin Xueer, and asked: "Are you really willing to do anything?"

Lin Xueer said without hesitation, "Really, I am willing to do anything."

The short Black Man laughed, "Okay, kill him. Then let us brothers have a good time here and spare your life!"

"Alright, thank you brothers!" Lin Xueer seemed to have grabbed onto the last straw of straw as she became excited.

"Lin Xueer, what are you doing? Are you going to kill me? " Du Rufei's eyes reddened, he could not believe it.

He knew that Lin Xueer was not a good woman, but he never expected that Lin Xueer was not even as good as scum.

Lin Xueer laughed sinisterly: "Du Rufei, don't blame me. If you want to blame something, blame yourself for being too unlucky."

"Lin Xueer!" Du Rufei's gaze was ice-cold and extremely furious, "I never thought that you were this kind of person!"
