Xue Yi and Black Lock came to the mist, and immediately more than a dozen fog demons surrounded them.

Before Xue Yi could make a move, the purple electric Tyrannosaurus Rex had already rushed out, and a mouthful of lightning erupted, and immediately a fog demon screamed and disappeared.

The skeleton dragon, on the other hand, spewed out a mouthful of dragon fire, and four or five fog demons were attacked, and disappeared without a trace in the screams. It seems that in terms of area attacks, the Skullsaurus is much stronger than the Purple Electric Tyrannosaurus Rex.

With these two dragons in front of them, and Xue Yi walking safely behind, there were no fog demons that could get close to them at all.

In a few minutes, the two dragons had already destroyed more than fifty fog demons, and the screams continued.

The other fog demons were shocked by the might of the two dragons, and they didn't dare to get even half a step closer to Xue Yi and the others. Even when he saw Xue Yi coming from a distance, he had already burrowed into the ground.

Gradually, the surrounding fog began to take on a faint red color.

Although in the mist, he couldn't tell the difference between southeast and west, but as long as Xue Yi walked towards the place where the red mist was darker, he would naturally be able to find the Mist Demon King.

......

At this time, on the edge of the blood pool, Ding Li and Wu Yingzi were already dying.

Wu Yingzi laughed dryly and said, "All along, I have had great hopes for Brother Xue and looked forward to him coming to save me. ”

"And now?" asked Ding Li, weakly.

"It's the same now, I know that Brother Xue will come eventually. ”

"Cut ......," Ding Li said disdainfully.

"Brother Xue will come to save us after all, but it seems that all he can save at that time is our corpse. Wu Yingzi laughed dryly again.

"These days, the Mist Demon King has thrown all those fierce beasts into the blood pool, and it is estimated that it will be our turn today. ”

While he was talking, seven or eight little demons dragged Ding Li and Wu Yingzi up and dragged them in the direction of the blood pool.

"You stinky mouth, come as you say. Wu Yingzi scolded Ding Li.

Ding Li didn't talk back, he had always spoken in a rough voice, and he actually let out a sigh at this time: "Alas...... I don't know what happened to Xue Yi. ”

The two of them had been escorted to the side of the pool of blood, and the pungent smell of blood came from the pool of blood, which made them cough incessantly.

The seven or eight little demons were about to push Ding Li and Wu Yingzi into the blood pool, when they heard screams in the distance, one after another.

The Mist Demon King on the Skeleton Throne by the Blood Pool heard this scream, and suddenly roared: "Roar-" stood up and walked in the direction where the scream came from.

But he hadn't taken two steps before the screams got closer. By the end, he could clearly hear it coming from the periphery of the blood mist.

The Fog Demon King was furious.

Dare to kill in my territory, deceive people too much!

He took a sharp breath, the blood mist around him was much thinner by him, and he took a big step to run towards the periphery.

But at this moment, suddenly a purple lightning bolt hit him.

The Mist Demon King couldn't dodge and was hit just in time. Although the lightning could not have had much effect on him, it also made him extremely uncomfortable.

"Roar—"

The Mist Demon King roared, and he was about to look at the guy who had attacked him.

At this time, a sudden heat wave hit, and a fierce fire broke out.

The Mist Demon King was caught off guard and was sprayed by the fire. His face was suddenly burned into a large pit by the flames, and he looked extremely terrifying.

"Roar—"

The Mist Demon King roared again, furious in his heart.

At this time, suddenly a figure of lightning rushed in, and a punch blasted out, hitting the feet of the Mist Demon King.

Bang –

There was a muffled thud, and there was an explosion in his foot. The explosion directly blasted the surface of his feet into flesh and blood.

"Whew-"

The Mist Demon King screamed miserably, couldn't stand on his right foot, and half-knelt on the ground.

"Roar—"

The Mist Demon King roared out again.

He was furious, really angry. It has been 10,000 years since he appeared until today. In the past 10,000 years, he has always pressed others to fight, and there has never been a situation like today, even before the opponent can see it clearly, and even suffered heavy losses. How could this keep him from being angry.

However, anger is anger, but the Mist Demon King has not lost his mind. It didn't immediately fight back against Xue Yi, but took a few steps back towards the depths of the blood mist, and then took a sharp breath, and the surrounding blood mist was suddenly sucked into his mouth. His body, which had been hit hard, was recovering at a rate visible to the naked eye.

The blood mist was absorbed, and a pool of blood not far away was revealed. The pool of blood continued to churn, continuing to produce blood mist, and in a moment, the entire blood pool was shrouded in blood mist again.

But before it shrouded, Xue Yi had already seen Ding Li and Wu Yingzi by the blood pool.

Seeing these two people, Xue Yi's heart let go of most of it, and the dragon power of the thunder and fire two attributes in his body was constantly running. The purple electric light flashed in the left fist, and the red fire flashed in the right fist, and the whole person suddenly jumped and jumped onto the feet of the fog demon king. Then he swooped three times and jumped to the back of the Mist Demon King.

Even if the Mist Demon King had four hands, it was impossible to catch Xue Yi on the back, so he could only keep turning around and waving his arms indiscriminately. In addition, the Purple Electric Tyrannosaurus Rex and the Skeleton Dragon took turns attacking the Mist Demon King on the left and right, making the Mist Demon King scramble and not caring about Xue Yi at all.

Xue Yi's left fist thunder attribute dragon power flashed, and then he used a critical attack to smash into the body of the Mist Demon King.

Bang –

The back of the Mist Demon King was blasted into a puddle of blood by the explosion of the critical hit.

Xue Yi's right fist fire attribute dragon power continued to crit.

Bang –

The blood pit suddenly became a little deeper.

Bang - Bang -

There were two more sounds, and the two critical hits directly blew through the body of the Mist Demon King, and a blood hole with a diameter of one meter penetrated through the front chest and back of the Mist Demon King, which looked extremely terrifying.

Xue Yi finished his four punches, and the dragon power on his body had been exhausted, so he jumped off the back of the Mist Demon King and returned to the two dragons. Press the backs of the two dragons with both hands to start absorbing the dragon power.

Originally, with Xue Yi's current strength, if he only used one kind of dragon power, he could blast out two critical hits. But he has two dragon powers, fire attribute and thunder attribute, so he can blast out four critical hits with all his might.

After the evolution of the Skeleton Dragon, the speed of generating dragon power was extremely fast, which could fully meet Xue Yi's dragon power needs. It was only at this time that Xue Yi could be regarded as having reached the true dual cultivation of thunder and fire. It was also at this time that the power of Xue Yi's Double Dragon Knight was truly revealed.

The two dragons, one on the left and one on the right, provided Xue Yi with dragon power while spitting flames and lightning to attack the Mist Demon King's chest, preventing his chest from healing so quickly.

With the Mist Demon King so seriously injured, his movements were naturally affected, and he became extremely slow, and he could only be beaten passively, unable to fight back at all.

More than twenty minutes later, the dragon power in Xue Yi's body reached saturation, and he flashed out again, and it was three consecutive critical blows, causing the Mist Demon King to retreat step by step.

Bang –

The last critical blow directly blew up the Mist Demon King with a miserable scream and sat down on the ground.

Xue Yi pressed his hands on the backs of the two dragons again, recovering the dragon's strength.

But at this time, Xue Yi was surprised to find that the recovery speed of the Mist Demon King was more than ten times faster than before. The bloody hole in his chest was rapidly healing, and the arm burned by the skeletal dragon was quickly growing.

Xue Yi's dragon power hadn't recovered a tenth of it, and the Mist Demon King had fully recovered, as if he had never been injured.

Xue Yi was surprised and looked at the place where the Mist Demon King was sitting. I saw that the Mist Demon King was sitting in the blood pool. The blood in the pool of blood is being consumed at a rate that is visible to the naked eye.

"Oops. Xue Yi said and hurriedly seized the time to absorb the dragon power.

But the Mist Demon King didn't give him a chance to continue absorbing at all, and with a wave of his long arm, he grabbed him directly.

Xue Yi hurriedly jumped back, dodging the attack, and the bloodthirsty sword in his hand appeared.

The Mist Demon King had the support of the blood pool at this time, and he had no scruples, and jumped into the blood pool with a roar, and his huge feet trampled the ground more than two meters deep.

Wu Yingzi and Ding Li on the side of the blood pool were splashed with the blood brought up by the Mist Demon King, and they only felt extremely fishy. Wu Yingzi hurriedly spat out the blood in his mouth and scolded: "Big demon, don't deceive people too much, I said a long time ago that my brother Xue would come to save us, this time I see how arrogant you are." ”

Although Ding Li was also dying like Wu Yingzi, when he saw that the battle between Xue Yi and the Mist Demon King was fierce, he couldn't help but exclaim: "Okay! Good job, brother!"

The Mist Demon King roared angrily and waved his four claws, grabbing Xue Yi again. Its twenty fingers were like twenty sharp swords, all of which were aimed at Xue Yi.

Xue Yi danced his bloodthirsty sword, unleashed a sword and a hundred shadows, and met the twenty fingers of the Mist Demon King.

Whew—

The Mist Demon King's fingers touched the bloodthirsty sword, and it turned into smoke and rose with a snort.

The Mist Demon King gasped and hurriedly stepped into the blood pool to absorb the blood and recover. But what frightened him was that the blood water didn't work at this time, and its severed finger couldn't be recovered.

Xue Yi saw that the bloodthirsty sword had a miraculous effect, and immediately danced the bloodthirsty sword and attacked the fog demon king.

The Mist Demon King knew that Xue Yi's sword was powerful, and he didn't dare to use his body to carry it anymore, wanting to dodge. But his body was too big to hide. Xue Yi swung out his sword, and one of the toes of the Mist Demon King turned into smoke and rose up.

Xue Yi succeeded in two moves, and he didn't stop, stepping on the body of the Mist Demon King, jumping towards the back of the Mist Demon King, the bloodthirsty sword swung, and stabbed directly at the back of the Mist Demon King's neck, and the entire bloodthirsty sword did not enter the back of the Mist Demon King's neck.

Suddenly, like a red-hot iron rod inserted into a snowdrift, the fog demon king's neck smacked and smoke rose. In less than a second, the bloodthirsty sword turned into a large hole with a diameter of one meter, which penetrated back and forth, and was extremely transparent.

At this time, the Mist Demon King covered the hole in his neck with his four hands, and wanted to inhale heavily. But how could his pierced neck inhale, he made a painful sound, his eyes protruded, and his chest continued to rise and fall violently.

After a while, the Mist Demon King could no longer stand, and fell to the ground like a mountain, crushing more than a dozen of the surrounding demons to death.

The Mist Demon King's two legs and four arms twitched continuously, looking at the bloodthirsty sword in Xue Yi's hand in disbelief.

After five minutes, it finally didn't move.

The 10,000-year-old fog demon king is dying.

When the surrounding little demons saw that the Mist Demon King was dead, they couldn't help but chirp and scream, scattered and fled, and disappeared completely in a moment.

It was only at this time that Xue Yi sat on the ground weakly. Fighting the Mist Demon King had exhausted him.
