Duan Feng mistakenly broke into the territory of the Black Demon Emperor, killed the Black Demon Emperor's pet eight sons, fought the Black Demon Emperor, killed the Black Demon Emperor, and obtained his qi yuan, and his qi realm increased again.

"To the left or to the right?" Duan Feng hesitated as he wandered through the basin.

The dark clouds in the sky were getting thicker and thicker, and occasionally a few muffled thunders could be heard from the depths of the clouds.

"Hmm, what is that?" Duan Feng noticed that there was a red patch in the clouds not far away, but the area was not large, and it was still moving slowly.

He flew forward, stopping beneath the cloud, the light rising upwards, and he followed the light deeper into the cloud.

"Is it a dragon?" Duan Feng wondered, the red light grew into a long strip, like a red ribbon floating in the clouds.

Duan Feng had never seen a dragon before, so he was a little excited in his heart, but his height was getting higher and higher, and the dense clouds around him began to thin out, but the clouds around that bright light were still thick.

The basin was at his feet, like a huge porcelain bowl, "It's too high, will there be any danger?" Duan Feng hesitated a little, but then dispelled his thoughts, "Being able to see the demeanor of the dragon, even if it is worth taking a little risk." ”

In order to be able to see the dragon's appearance clearly, he drove the Ice Sword to climb quickly, gradually approaching the red cloud.

"No! It's not a dragon!" Duan Feng was shocked, although he had never seen a real dragon, he had never heard of a dragon clone.

But the red strip just now suddenly split into eight and rushed out of the clouds, "It's eight red snakes!"

"What kind of spirit beast is this?" he called them spirit beasts, but they were faster than any spirit beast he had ever seen before.

Duan Feng confirmed that they hadn't discovered themselves yet, as they were busy burrowing into the clouds and then out, as if they were attacking the clouds.

Duan Feng knew that something was wrong, so he retreated a few hundred feet, hiding in a cloud of mist and quietly observing the clouds.

After a while, the entire cloud began to dissipate, and in addition to the eight red snakes, there was a huge animal corpse in the air, which was the same giant beast that roared on the ridge before.

Eight long snakes kept shuttling back and forth in the corpse until there was no more flesh on the corpse, and only a skeleton of Bai Sensen remained.

The serpent continued to circle around the skeleton a few times, making sure that there was no flesh left, so it stopped eating, and then merged into one, the body of the merged snake did not elongate, but the color of the body was more vivid, like a long glowing lantern.

Duan Feng was a little frightened and a little puzzled in his heart, "After eating such a big giant beast, their bodies didn't even react at all. ”

Just as Duan Feng was about to leave, suddenly the head of the long snake turned and pounced on him, the speed was as fast as lightning, so that he didn't have time to dodge, so he could only fly and jump, stepping on the clouds and holding the cold ice sword, and raised the sword to face him.

"Whew!"

The red snake swept through the clouds, grazing the blade of the cold ice sword, Duan Feng only felt a fire dragon passing overhead, and then the red snake appeared in the sky a hundred zhang away from him, and he was blown away by the shock wave brought by the red snake.

Duan Feng's body descended rapidly, he concentrated the aura in his hand, and used the water qi technique in the qi control technique to continuously increase the density of water vapor in the dense cloud under him until he could bear his weight.

The powerful aura emanating from the Red Snake that he could feel was comparable to the previous Ice Snake, and the Ice Snake's entire body exuded an extremely cold aura that had no effect on the Red Snake at all.

Duan Feng thought to himself, it is said that the spirit beasts of the Borderland gather, and the immortal beasts often come and go in it, but since they are immortal beasts, why do they act so viciously? He involuntarily looked at the skeleton that was still floating in the air.

But not allowing Duan Feng to think too much, the red snake adjusted its direction again and attacked him, Duan Feng adjusted his mentality, since he couldn't avoid it, he could only face it, not to mention, he had never fought with the immortal beast yet, so he just took this opportunity to test the golden qi technique he had just practiced.

However, Duan Feng was not confident in his Water Qi Technique, after all, the air here was too dry, and the spell just now had consumed too much of his energy, and he couldn't waste too much spiritual power on it. To be on the safe side, he had to get back to the ground so he could play to his advantage.

Before Duan Feng could return to the ground, the Red Snake was already approaching behind him, and suddenly, the Red Snake was once again divided into eight, with a bloody mouth, revealing sharp fangs that flew around Duan Feng from behind him and flew in front of him.

"Surrounded!" Duan Feng stopped urgently, and eight red snakes surrounded him, ready to attack at any moment.

Duan Feng was still a little panicked in the face of the red snake who suddenly split up just now, but after being surrounded by the red snake, he suddenly calmed down, and the sword under his feet began to glow with a light blue light.

"Hurry!"

Duan Feng roared, and pointed his arms to both sides, and the ground suddenly shook in between, and tens of thousands of stones on the ridge next to him began to fly up slowly, faster and faster, gradually forming two huge stone balls.

Duan Feng's eyes were firmly fixed on the three red snakes in front of him, and his arms moved slowly, "Huh!"

Two huge stone balls flew towards the air at a high speed, Duan Feng suddenly jumped over, reached out and picked up the ice sword under his feet, turning into a white lightning bolt and rushing forward.

At this moment, the two stone balls were on the verge of the red snake's periphery, and Duan Feng raised his sword and quickly turned around to avoid one of the red snakes.

"Bang!"

The two stone balls collided together, instantly splitting into countless fireballs, Duan Feng took advantage of the situation, and with a wave of the big sword, a sword qi flashed across the air, hitting one of the red snakes, according to Duan Feng's consciousness, the red snake would definitely be cut off by the sword qi, at least seriously injured.

But to his surprise, as soon as the sword qi touched the red snake, the red snake suddenly turned into a puff of red smoke, and the original eight red snakes became seven again.

He wasn't sure if the other red snake was dead, but countless fireballs stood in front of him, and the other seven red snakes were about to surround him again, Duan Feng withdrew his ice sword, and his hands harnessed countless fireballs to scatter in all directions.

Gradually a huge barrier of fireballs formed around him.

Duan Feng stood in the center of the barrier, staring coldly at the red snakes outside, now they had become one again, and the color was even brighter, but the length was shorter than just now.

But its speed is also much faster, a spherical barrier with a diameter of 100 zhang, the red snake can circle in the blink of an eye, and after being convinced that there is no chance to take advantage of it, the red snake is ready to launch a strong attack.

"What kind of creature is this? Why is it so unaware? Duan Feng wondered in his heart, it is the instinct of all species to seek advantages and avoid harm, and the battle has reached this level, this red snake does not seem to have the slightest intention of retreating, but is becoming more and more courageous the more he fights.

Duan Feng harnessed the barrier around him and spun rapidly, gradually forming an airtight spherical shape around him, he was sure that there were no dead spots for the Red Snake to attack, and if it wanted to attack, it would first have to rush through the countless fast fireballs that were spinning rapidly.

"Bang bang bang!"

With countless impacts, Duan Feng felt that a strong force was hitting his body, and the Red Snake really launched a strong attack, although this was something he expected, but he didn't expect the Red Snake to have such a powerful force.

However, Duan Feng didn't use all his strength, he began to play to his advantage, "Since you broke in, then don't go back!" Duan Feng sneered, flew out of the barrier, concentrated the aura on his hands, and slowly narrowed the barrier.

"Bang bang bang!"

The Red Snake was still rushing into countless fireballs, while Duan Feng had already returned to the ground, coldly looking at the fireballs that were constantly exploding in the air.

"Die!"

The fireball began to spin faster, and countless stones began to converge rapidly towards the center, and the original barrier began to become dense.

There were still stones flying into the air, and the barrier that was originally a hundred zhang in diameter was now reduced to less than a hundred meters, and the explosion sound inside was getting smaller and smaller.

"I see how you're doppelgänger now!"

Duan Feng gritted his teeth and prepared to launch one last attack on the Red Snake.

"Boom!"

A stone ball about ten meters in diameter formed in the air, and the red snake was tightly wrapped in the stone ball, and the density of the entire stone ball was more than ten times greater than that of ordinary stones, which was enough to crush all living things.

The red snake twisted and struggled among the stones, roaring, but the stone ball shrank tighter and tighter, giving it no time to breathe.

Duan Feng felt that the time was ripe, withdrew his spiritual power, kicked the ground with both feet, and flew up, the cold ice sword in his hand flashed with cold light and quickly stabbed at the falling stone ball.

"Bang!"

With a loud bang, Duan Feng appeared on the other side of the stone ball, and a one-meter-diameter hole appeared in the center of the stone ball, and half of the red snake's snake body flew into the air along with the stone that was knocked out.

"Boom!"

The stone ball eventually landed, leaving a bottomless hole in the ground with a diameter of ten meters.

Duan Feng knelt down on one knee with a loud breath, gasping for breath, he had consumed too much aura in this battle, "I didn't need to use so much aura in the first place." Duan Feng looked at the half-fading snake and thought, but he didn't understand the power of the Golden Qi Technique, so he had to do his best to be on the safe side.

Duan Feng thought to himself, after learning so many skills, he was a little hesitant at the critical moment, just now he wanted to establish a field first, but after hesitating, he should use the Golden Qi Technique, which made him waste some spiritual energy in vain.

In the future, you need to determine which technique to use before fighting, otherwise it will be a waste of aura, not to mention, it is more likely to give the enemy a chance to take advantage of.

After resting for a while, Duan Feng looked up at the sky, the dark clouds had been thick for a long time, but when he passed through the clouds just now, he vaguely saw the light emitted by the flames of the Netherworld Abyss.

Duan Feng felt a little strange in his heart, this red snake didn't have a qi element, "Isn't it a spirit beast?", but its aura is very strong, "Could it be a demon beast?" But demon beasts also have qi elements.

He couldn't figure it out, among the beasts in the world, in addition to the demonic beasts, demon beasts, immortal beasts, and spirit beasts with qi elements, they were ordinary beasts without qi elements, but how could ordinary beasts have aura?

Duan Feng scratched his head strangely, packed his bags, flew on his sword, and flew towards the direction of the Netherworld Abyss.

"Boy, give me back my eight sons!"

Suddenly, a voice came from behind him, Duan Feng was taken aback, and when he looked back, there was no one, he thought it was an auditory hallucination, in this kind of place, anything can happen, so he prepared to continue leaving.

Suddenly, a cloud of black gas blocked his way.

"Boy, kill my eighth son, leave like this, where to put my Black Demon Emperor!"
