Duan Feng fought against the Black Demon Emperor, killed the Black Demon Emperor, and gained his qi.

"Black Demon Emperor? Duan Feng's heart was happy, but then his nerves tensed again, because a frightening figure appeared behind a pompous name.

The black qi quickly swirled around Duan Feng, but the sound kept coming from the front, and he didn't know how to determine the location of the comer.

"Hmph, boy, where is all that arrogance just now?"

Duan Feng watched the surroundings vigilantly, and the air around him began to flow rapidly, and the black gas gradually formed a vortex around him.

Duan Feng wanted to break out of the whirlpool, but he was immediately taken back by the black qi.

"Who are you?"

"Hmph, boy, you're very bold, first caught my ghost fireworm, and now I'm killing my eighth son, today I have to kill you!"

Before the words fell, a cloud of black qi flew over, and he jumped, and the black qi passed through his crotch.

"Good boy, I'll play with you first. ”

In an instant, a blue aura formed from the edge of the vortex.

"Poof!"

The aura suddenly contracted, Duan Feng flew to dodge the attack of the aura, followed by the second and third, and then the continuous aura continued to converge from the center of the whirlpool, contracted, and then turned into a point of light and disappeared.

Duan Feng didn't know how powerful the aura was, but judging from the heat wave emitted by the aura, it must not be underestimated.

"Hahaha!"

"What are you laughing at?" Duan Feng said angrily.

"That's all there is to it?"

Duan Feng gasped, the aura just now was too much consumed, and now he was a little powerless in the face of the attack of the aura.

"Whoosh!"

Suddenly, the aura that had originally gathered towards the center began to fly upwards rapidly, gradually forming a blue concentric pillar of light, trapping Duan Feng in the center.

The temperature inside the pillar of light instantly increased, and Duan Feng rushed upwards rapidly, but the pillar of light also rose rapidly as he rose.

"It's too hot!" Duan Feng wiped the sweat from his head, but the temperature in the pillar of light was still rising rapidly.

"No, I can't stand it!"

With Duan Feng's order, the cold ice snake rushed out, Duan Feng continued to rise with the cold ice snake in his arms, "Comfortable!" Duan Feng put his face on the snake and looked up at the exit in front of him.

The pillar of light began to shrink gradually, and Duan Feng distinctly felt a wave of energy slowly approaching from all around, and the range of movement of the Ice Snake gradually shrank.

Whenever it touched a pillar of light, it would cause a burst of electric light, which did not cause it harm, but it also made it estimate that it did not dare to touch it easily.

"Good boy, not dead yet!"

"Bang!"

Concentric pillars of light instantly merged, leaving a ribbon of light tens of thousands of meters long in the night sky.

The black gas flew from bottom to top along the band of light, but no trace of Duan Feng was found.

"Could it be gasified? impossible, there must be some traces of gasification, but why isn't there any aura around?"

The black gas went around the top of the light band and searched again, but still found nothing.

"Boom!"

Suddenly, a point of light slammed into the black gas from behind.

"Haha! Lao Tzu didn't die so easily!" Duan Feng stood in a small transparent bottle and laughed as he passed through the middle of the black qi.

"Qiankun Chaos Bottle!" The black qi suddenly turned into a human figure and floated in the air, looking at Duan Feng with an incredible look.

"How can you have such a treasure? Who the hell are you?"

"Yo! You're pretty knowledgeable! You don't have to worry about that. Duan Feng came out of the bottle and returned to its original size, "You are the Black Demon Emperor? ”。

The Black Demon Emperor's whole body was surrounded by a thick layer of black qi, only a pair of eyes flashed yellow, and he held a sword in his hand that was also shrouded in black qi.

"Stinky boy!

Although the Black Demon Emperor was surprised by the Chaos Qiankun Bottle in Duan Feng's hand, he didn't show any fear, but this made him more interested.

In his heart, the person who can possess this ancient artifact will definitely not be an idle person, but what makes him wonder is that this kid in front of him, who is young and has mediocre spiritual power, how can he have such a treasure.

The Black Demon Emperor waved the long sword in his hand, his body did not move, and after a sword qi left the blade of the sword, it instantly turned into ten thousand paths and flew towards Duan Feng from all directions.

"Huh?" Duan Feng's eyes were stunned, "Isn't this a move in the Imperial Sword Technique?" "He had practiced for so long that his face was not counted, and this Black Demon Emperor was actually able to exert its final form.

"Flying Sword to the Sky" is a move in the Imperial Sword Technique, in which the final form is to divide a sword qi into ten thousand paths, attacking the enemy from different directions, and each sword qi has the power of the original sword qi at the same time.

Moreover, the flying sword that this Black Demon Emperor cast was actually mixed with a sinister aura!

Duan Feng didn't have time to think about it, the ten thousand sword qi had already flown in front of him, and he hurriedly flew back and retreated, breaking away from the encirclement of the sword qi as quickly as possible.

But these sword qi were like eyes, and wherever he flew, they followed closely behind, not giving him the slightest respite.

Duan Feng waved his right hand back, and a wall of qi formed in an instant, but a sword qi broke through the wall of qi.

Then he used all his strength to manipulate countless fast crushing stones behind him to form a dense stone ball with a diameter of one zhang.

"Bang!"

Again, the stone ball was instantly beaten into powder.

"Damn!" Duan Feng thought to himself, with the strength of this Black Demon Emperor, even if he had sufficient strength, he was probably not his opponent, if he didn't use some special means, he would probably die here.

He pulled out the incinerator from behind him, "There are no human beings here anyway. He opened the lid wide, grabbed the foot of the stove, and waved it back.

"Poof!"

Dozens of sparks flew out and turned into flames, forming a wall of fire behind him.

The sword qi struck the wall of fire and disappeared in an instant.

Duan Feng looked at the incinerator and smiled proudly, "Now it's my turn to make a move!" He quickly turned around and aimed the furnace at the Black Demon Emperor and flew quickly.

The Black Demon Emperor's face was shocked again, "The Burning Sky Furnace is also in the hands of this kid!", but then he regained his composure, "Who is this kid?"

At this time, the wind has rushed to the front of him, and he roared: "Let you also taste the taste of being burned!"

"Whoosh!"

Two flames rushed out of the incinerator and went straight to the Black Demon Emperor, Duan Feng also knew the power of this ancient artifact in his hand, so he looked at the Black Demon Emperor proudly.

But to his surprise, before the flames could turn into flames, the Black Demon Emperor disappeared in an instant.

"Carving insect skills!"

The Black Demon Emperor roared, and the flames that were originally flying forward suddenly reversed direction for some reason and flew towards Duan Feng.

"I'll go!"

Duan Feng couldn't dodge and was hit in the chest by the fireball, but it didn't hurt him, just knocked him to the ground.

Duan Feng got up, looked at the fireball that fell on the ground, slowly extinguished, and began to panic a little in his heart, this kind of flame can incinerate everything in the Three Realms, and it will form a raging flame when it lands, and it will definitely not be extinguished if it is not burned, but now, in this basin overgrown with dry grass and dry air, the fire has been quickly extinguished, and not even a spark has been caused.

Suddenly, the Black Demon Emperor appeared above him again, and the great sword in his hand spun and rushed down.

"Walk you!"

Once again, Duan Feng threw the fireball in the incinerator into the air, and then jumped to the top of a mountain peak.

As before, the fireballs that had escaped were silently extinguished again, and the flames of the incinerator seemed to have lost their effect here.

"Hey, hey, boy, don't think you can do whatever you want with this incinerator, and don't look at what this place is!"

"Isn't it the edge of the Borderlands, is there anything special about it?" Duan Feng thought to himself.

Suddenly, Duan Feng felt that his right hand was being tightly grasped by a large hand, he turned his head, and a row of white teeth appeared in front of him, and his yellow eyes were staring at Duan Feng's eyes.

Duan Feng was startled, and swung his sword with his left hand to stab back, but then his left hand was also grabbed by another big black hand.

"Bring it to you!"

The Black Demon Emperor's right hand was forced, Duan Feng only felt that his right hand was numb, and the incinerator in his hand fell off from his hand, and the Black Demon Emperor took the incinerator and looked at it proudly.

Taking advantage of this opportunity, Duan Feng's right elbow slammed backwards hard, and his left hand broke free from the restraints, and his body quickly left the Black Demon Emperor and flew out of the hundred zhang.

Duan Feng looked at Kong Kongru in disbelief and saw that there was still a crimson blood mark on his wrist.

"Oh no!" Duan Feng thought to himself, "Without the incinerator, this is still an eggplant!"

"Boy, if you have any other skills, use them!" The Black Demon Emperor put away the incinerator furnace, he didn't intend to use it against Duan Feng, but continued to raise the sword in his hand.

"Damn! heroes don't eat immediate losses!" Duan Feng ignored the Black Demon Emperor, but instead plunged into the Qiankun Chaos Bottle and quickly retreated towards the east.

As soon as the Black Demon Emperor saw that Duan Feng wanted to run, a sword qi flew out, and then ten thousand sword qi struck the bottle, leaving only one point of light, Duan Feng sat inside, looking at these points of light like looking at the stars, and was very proud in his heart.

Originally, he wanted to pursue, but the pursuit stopped halfway, and then he thought about it, if Duan Feng hid in the bottle and didn't come out, he really didn't have any way, the Qiankun Chaos Bottle was not something that could be broken by just one person from the outside, it took the Evil Emperor 10,000 years to escape from it back then, thinking of this, the Black Demon Emperor secretly wondered in his heart, "How did this Evil Emperor escape?"

But since it took tens of thousands of years for the Evil Emperor to escape from it, with his own little tricks, it was even more impossible to break it, so he could only watch Duan Feng escape from his attack range.

Duan Feng was annoyed along the way, complaining that he was too light and careless, if he hadn't entangled with the Black Demon Emperor at that time, the Incineration Furnace would not have fallen into his hands, and now that the Incineration Furnace is gone, he has also been injured.

Fortunately, the ghost fire insects were still there, and besides, he was locked in the bottle at the same time as these, and they didn't even attack him anymore, which made Duan Feng very puzzled.

But fortunately, although this trip lost the incinerator, but it was also a gain, in addition to successfully capturing the ghost fire worm, he also saw the power of the so-called Borderland, although it was only the edge, but it was enough for him to blow for a while.
