Twin sword potential, one yin and one yang, one attack and one defense, at this stage of the Sword Sect, the actual strength cultivation can no longer measure a person's strength or weakness, but use the moves, supernatural powers, and your mastery and changes in the exercises.

This is why demon cultivators of the same level will have a great advantage over human cultivators of the same level, because demon cultivators basically have natural powers, while humans need to use their own wisdom to slowly comprehend, break through, and create.

Just like there are so many Sword Sect-level cultivators in the Shenzhou World, and there are not a few who are cultivating in the late stage of the Sword Sect or even the Great Perfection, but there are only a few strong people in the younger generation.

Strength lies not only in strength, but also in the realm.

It is very simple for a person to gain power, but it is undoubtedly difficult to master the power he has obtained and be able to use his power in the most reasonable way to achieve the highest harvest at the lowest cost.

Twin sword momentum, this is the move that Yi Chen relies on to have a place in the Sword Sect at this stage.

Two sword qi, one black and one white, the black sword qi is yin, the sword qi buzzes, and bursts of bone-chilling and killing intent are revealed, making the grass and trees wither, and making everything depressed.

The white sword qi was yang, hovering around Ye Qing's body, forming a solid sword qi shield.

"All things are negative yin, gather to embrace yang, yin palms live and die, and yang nurtures the common people. Yi Chen's arms danced, and with a finger of the long sword in his hand, the extreme yin sword qi instantly turned into a black sword light.

'Buzzing' on the earth, in the sky, one after another black points of light began to condense, they continued to merge with the Extreme Yin Sword Qi, and the Extreme Yin Sword Qi gradually began to emit an extremely strong Black Sword Light.

'Huh' The Extreme Yin Sword Qi let out a long groan, and with a thrilling force, it flew towards the falling Flame Spear.

"The fire of Nirvana, burns everything. Ling Yuan glanced lightly at the flaming spear that fell like a rainbow, her gaze was calm. Both hands pinched out a magic seal, and then an extremely powerful flame 'bang' appeared in his hand.

The flame of Nirvana was beaten out by Ling Kite, and it flickered constantly in the process of flying out, as if it was extremely faint and could be extinguished by a gust of wind, but if you think so, it would be wrong.

I saw gusts of wind blowing on the fire of Nirvana, and not only did it not extinguish it, but the fire of Nirvana burned those gusts of wind as if the air was burning. The fire of Nirvana, legend has it that it can burn away nothingness.

The aura in the air is absorbed by the fire of Nirvana, and the fire of Nirvana continues to grow.

At this time, the powerful power of the Extreme Yin Sword Qi gradually spread, and sand and rocks flew on the ground. Streams of energy raged, setting off gusts of wind.

And the momentum of the flaming gun is not bad at all. Two forces are black and red in the sky. Like two shooting stars. They crashed into each other quickly.

The energy like the 'boom' sea tide poured down frantically, the earth trembled, the flowers and trees in the entire area were all uprooted, and a barren vacuum area appeared, except for the Sword Sect monks on the ground, all the demon soldiers and innate monks were knocked to the ground by this huge energy. Some were even lifted out hundreds of meters in a row, and they were shocked to death.

'Bang' 'Woo' The long sword in Yi Chen's hand was connected to the Extreme Yin Sword Qi, and at this time, the Extreme Yin Sword Qi collided with the Flame Spear, and the huge energy explosion directly affected Yi Chen.

'Click' A crack began to appear on the long sword in Yi Chen's hand. Yi Chen's face changed, although this sword was not a psychic sword, but it was refined with extremely precious thousand-year-old Hanxi iron, I couldn't imagine that the sword that had gone through so many battles for so many years without the slightest damage, but today there were cracks, which showed how strong Ling Kite's strength was.

And the flame spear, at the moment when it broke through the Extreme Yin Sword Qi, was suddenly shocked by the huge force that burst out later, and after a few reversals in the air, it was inserted into the ground with a 'poof', and the fiery red body of the spear directly sank into the ground half a meter long, and the blazing breath baked the surrounding sand and stones red.

The fire of Nirvana had come to Yi Chen's eyes in the blink of an eye, and Yi Chen could even feel the destructive power contained in the fire of Nirvana.

As soon as the 'Zizi' Nirvana Fire approached, Yi Chen's hair began to burn.

Yi Chen was startled, with a push of his palms, an obscure aura rose from his body, and then dazzling white light began to appear between heaven and earth, these white lights quickly flew towards Yi Chen, and merged into the Extreme Yang Sword Qi outside Yi Chen's body, and suddenly, the Extreme Yang Sword Qi burst out with a dazzling white light, and a thick layer of sword qi light appeared outside Yi Chen's body, and the power of Nirvana Fire was immediately blocked.

Yi Chen's eyes widened, and he shouted loudly, "Yin and yang alternate, attack and defense are orderly." "'Canopy' An Extreme Yang Sword Qi flashed within the sword qi light cover, and an Extreme Yin Sword Qi turned out from Yi Chen's dantian in the form of a sword element, Yin and Yang merged, and suddenly transformed into a brilliant black and white sword qi.

The black and white sword qi shot out, with a trace of destructive power, and went towards the fire of Nirvana with a 'boom'.

"Burn!" Ling Yuan's mouth opened lightly, and the fire of Nirvana suddenly turned into a large piece of firelight, enveloping the black and white sword qi in it.

"Fire is yang, and yang gives birth to yin. The magic trick in Yi Chen's hand was struck, and the dazzling black light of 'Hum' shone up, and the fire of Nirvana was immediately like a solar eclipse of the sun, and an extra round of black sword light appeared in the middle.

The scorching aura of 'hum' instantly spread throughout the entire battlefield, whether it was a demon or a demon, the battlefield gradually shifted to a remote area, and here, only Yi Chen and Ling Yuan were left.

"Nirvana fire, divine fire is invincible!" Ling Yuan shouted, two divine lights suddenly shot out of his eyes, and the two rays of light submerged into the Nirvana fire, and suddenly the Nirvana fire was full of momentum, suppressing the black sword light inside.

"What a powerful phoenix divine fire. "A trace of horror flashed in Yi Chen's eyes, the Extreme Yin Sword Qi was like water, if 'water' appeared in the heart of fire, then the fire would definitely be extinguished, but this fire of Nirvana directly suppressed the 'water' back, isn't it very perverted?

"Turning yang into yin, life is endless. Yi Chen shouted, and suddenly there was a more violent shock inside the Nirvana Fire, and the Extreme Yang Sword Qi in the Yin and Yang Sword Qi began to continuously absorb the Extreme Yang Qi in the Nirvana Fire, and then transformed it into the Extreme Yin Qi.

Borrowing strength, the power of yin and yang, the extreme of creation.

Ling Yuan's face changed drastically, and she clearly felt that the power of the Nirvana Fire was constantly being devoured.

"Damn!" Ling Yuan looked at the Extreme Yin Sword Qi that had grown again in the Nirvana Fire. Even about to devour and extinguish her nirvana fire, she looked cold, resolutely bit the tip of her tongue, a trace of pain flashed in her eyes, but then she opened her mouth, a mouthful of essence blood spurted out, essence blood fell on the fire of nirvana, and in an instant a fire rose to the sky.

With a clear roar, the fire that rose into the sky suddenly turned into a fire phoenix, and this fire phoenix circled in mid-air for a while. Flew back into the fire of Nirvana.

'Boom' Nirvana's fire was magnificent, and the Nirvana fire with the phoenix's essence blood was like a huge fire phoenix, the flames were monstrous, and everything on the earth began to burn under this scorching temperature.

That Extreme Yin Sword Qi gradually began to be devoured by the fire of Nirvana, it was devouring. And not suppression!

Yi Chen's dark color changed greatly, but he couldn't care about it so much. There was a glint in his eyes. With his hands together, he formed a sword finger and pointed at the Extreme Yin Sword Qi that had been devoured for the most part, "Extreme Yin Turns Yang!"

Everything in the world is not absolute, there is yin and yang, there is fire and water, and there is life and death. As much as there is, there is less.

If there is only yin and no yang, then we will always be able to live in darkness and dampness.

If there is only fire and no water, then the world we live in will be a sea of fire.

If we are born without dying, then our world will no longer be able to accommodate so many living beings.

If only more and not less. Then society will swell, and the world will swell, until it swells to an extreme, and finally it will be destroyed.

The fire of Nirvana is originally the fire of the extreme yang, which is claimed to be able to burn all things, and it is the fire of the extreme yang, why did Yi Chen still turn the extreme yin sword qi into the extreme yang sword qi?

This was also Yi Chen's temporary idea, because the fire of Nirvana was constantly devouring his Extreme Yin Sword Qi, and it was impossible for him to stop it if it went on, and devouring the Extreme Yin Sword Qi would not have any effect on the Fire of Nirvana, but would grow stronger and stronger.

And if the Extreme Yin Sword Qi is turned into the Extreme Yang Sword Qi, it can be described in one sentence, that is, the result of continuously pumping into a balloon that was already full of gas

A person's body focuses on the harmony of yin and yang, and the absorption of extreme yin sword qi by the fire of nirvana also happens to play a role in strengthening and harmonizing, so Yi Chen resolutely decided to transform the extreme yin sword qi into extreme yang sword qi.

Sure enough, under the continuous devouring of the fire of Nirvana, the Extreme Yang Sword Qi continued to merge into the fire of Nirvana, and the fire of Nirvana began to grow, the fire light became more and more vigorous, and the energy became stronger and stronger.

At first, Ling Kite's face was full of joy, but then, she sensed that something was wrong.

"A demon is a demon, if you don't understand the truth that if the water is full, it will overflow, and the extreme of things will be reversed!" Yi Chen sneered, Ling Yuan ignored Yi Chen's sarcasm, and frantically wanted to take back the Nirvana Fire, and at this time, the Nirvana Fire had begun to emit a trace of incomparably terrifying energy, and even Ling Yuan himself could feel the destructive power contained in it.

"Stop me!" The Nirvana Fire was still devouring the Extreme Yang Sword Qi continuously, and Ling Yuan was horrified to find that he couldn't make the Nirvana Fire stop devouring the Extreme Yang Sword Qi at this time!

Eventually, the fire of Nirvana grew bigger and stronger, and a dazzling flame suddenly appeared.

As soon as the earth-shattering explosion sounded, the monstrous flames soared into the sky, the earth turned red, the mountains and forests were red, and all within a radius of 300 meters turned into a sea of fire.

Xiang Yichen and the others were surrounded by tens of thousands of demon soldiers, and when they were fighting bloodily, they suddenly saw a dazzling fire in the distant sky, reflecting the entire sky, and even the clouds became red.

Subsequently, the overwhelming flames swept in, and the first to suffer were those demon soldiers on the periphery, the flames burned to the touch, and even some of the demon soldiers of the Lingmu clan were just stained by the flames and turned into ashes.

The Heavenly Demon Army, which is all the elites selected from the hundred races of the demon world, is transformed into a body through the demon temple, although it is exempted from hundreds of years of penance to transform into a human body, but the strength has not grown, and the transformation is only the body, and the soul and wisdom will not be there.

And the fire of Nirvana was extremely fierce, and at this time, it was even added to a lot of extreme yang qi by Yi Chen, which could be said to ignite when touched, and so many demon soldiers stood together densely, like a match that was inserted together, and the fire began to spread in an instant.

This is not an ordinary fire, this is the fire of nirvana among the three extreme yang fires!

"Be careful, everyone. Shouted to Yichen.

Then, a thick smell of burnt paste began to spread, and the fire was everywhere.

"Spread out, all spread out. "The Black Bear General, the Silver Wolf General and others quickly sacrificed the power of protecting their bodies. Shouted frantically at the demon soldiers.

The sound was endowed with spiritual power, and it spread extremely quickly, and soon the demon soldiers began to disperse, although the contagious burning was curbed, but the flames that spread in the air still threatened everyone.

"Ah!!" A miserable scream came, and a Nirvana fire suddenly burst out from the top of a disciple of the Hidden Sword Sect, engulfing him in an instant.

Everyone in 'Zizi' didn't even have time to react, and watched as the disciple turned to ashes.

"No!" At this time, there was another terrible scream, and a female disciple of the Haoyue Sect had a distorted face. Her left arm was already full of blazing flames, and in an instant, half of her left hand revealed charred bones, and her terrible cry shook everyone.

Xiang Yichen stepped to the female disciple's side with the long sword, "Hold on!" Xiang Yichen grabbed the female disciple's burning arm, and the long sword in his hand slashed down.

'Click' has no blood. There wasn't even a trace of blood, and Xiang Yichen's severed arm was severed. It has been completely scorched. Soon it will burn to the shoulder.

The female disciple was frightened by the painful torture and the terrifying scene, and her eyes turned white and she fainted.

"Spread out as much as you can, don't move, don't move. Xiang Yichen hugged the fainted female disciple and turned his head to shout at the remaining two sect disciples.

Everyone understood that at this time, nine out of ten demon soldiers who were running frantically to escape from this area were on fire again. It is because the amplitude of their movements is so great that the power of the Nirvana fire hidden in the air will be ignited in an instant as soon as it touches the friction.

The battlefield has turned into a terrifying purgatory, with charred bones everywhere. There are animals, there are humans, there are half-humans, half-animals, everywhere, and even stumps and broken arms are sprinkled all over the ground, desolate and miserable.

"Old thing, dare to hurt my Nirvana fire!" Ling Kite's face was full of hideousness at this time, the Nirvana Fire that had been cultivated by herself for so many years had lost most of it under Yi Chen's control, and what she forcibly saved was only a small part, the Nirvana Fire of the Phoenix Clan had been cultivated since the innate time, and it was not until the Sword Emperor could take shape and become the Origin Fire, but at this moment, decades of hard work were all destroyed, how could she not be angry?

Yi Chen clutched his chest, spit out a mouthful of essence blood, his face turned pale, the fire of nirvana was coming at him, although he was detonated by him with extreme yang qi, he still suffered most of the damage.

At this moment, he felt a burning pain in his internal organs, as if he had been burned by fire, and his blood was about to be burned dry.

The spiritual power in the dantian was consumed a lot by the impact just now, and the extreme yang sword qi outside his body helped him block a lot of power.

Although it is not depleted, it is already halfway there.

'Huh' Ling Kite's face was full of anger, and with a move of his hand, the flame spear in the distance instantly pulled out of the ground, turning into a fiery red streamer and flying back into Ling Kite's hand.

"Death! Phoenix seeks the phoenix!" Although Ling Yuan was hit hard because of the fire of Nirvana, most of the heavy damage was due to strength, and the physical injuries were not serious.

At this time, the Flame Spear brought out a fierce light, and Ling Kite's fiery red body merged with the Flame Spear, killing Yi Chen at an extremely fast speed.

"Extreme Yang Poof" Yi Chen pinched the magic trick in his hand, but as soon as he said two words, he spurted out another mouthful of essence blood.

"Extreme Yang Protective Body!" Yi Chen shouted, 'groaning' A sword light rose into the sky, and an Extreme Yang Qi protected the outside of the body.

The 'boom' flame spear slammed against the Extreme Yang Sword Qi, Yi Chen's body shook violently, and his face froze, "Give me a retreat!"

'Bang' Extreme Yang Sword Qi suddenly erupted, an extremely strong force collided with the Flame Spear, and in an instant, the fire burst out, a huge amount of energy burst out, and with a heavy 'poof', the Flame Spear and Ling Kite were shocked back at the same time, a trace of blood overflowed from the corner of Ling Kite's mouth, and Yi Chen spit out a mouthful of essence blood again, and the momentum on his body was even weaker.

"The physical strength of the demon clan is really strong, and the human race is indeed in a weak position in this regard. Yi Chen looked at the majestic Ling Kite standing in the air, and sighed helplessly in his heart.

"Today, I will kill you!" Ling Kite's murderous aura was awe-inspiring, and the flame spear in his hand stabbed out again.

In the distance, although the demon soldiers suffered great losses, there were still more than 10,000 people who survived, but they did not dare to act rashly at this time, and several deputy generals of the demon clan and Xiang Yichen, a disciple of the two Sword Sects, did not fight again, but watched nervously the battle between Ling Yuan and Yi Chen.

"Uncle Yi. Xiang Yichen watched Ling Yuan kill Yi Chen violently, and Yi Chen's situation was already extremely dangerous. But they couldn't help, because they still had the demon clan lieutenant general in front of them.

"Uncle Yi Chen. Luo Xue also exclaimed, and even some disciples such as Ye Li'er had closed their eyes in despair, "Isn't even Senior Uncle Yi Chen able to defeat that demon girl?"

As soon as Yi Chen died, what would they do? This was the reason why all the disciples were nervous and hesitant in their hearts.

"The demon cultivator of the Phoenix clan has the blood of the phoenix, although the strength is similar to that of Uncle Yi Chen, but the supernatural power and physical strength mastered are far beyond the monks of the same level, Uncle Yi Chen suffered a loss in the fire of Nirvana, and the fire of Nirvana will not hurt the demon cultivator of the Phoenix clan, because they belong to the same body, she will just be severely injured by Uncle Yi Chen because of the fire of Nirvana and will be damaged in cultivation. Xiang Yichen said bitterly, the demon race is too much beyond the human race in terms of innate aspects.

Just when the Flame Spear and Ling Kite had already rushed in front of Yi Chen, Yi Chen had to fight to the death

"Stop!" A loud shout sounded, and then a sky-high sword light flashed, and the amazing sword momentum exploded, everyone looked, only to see a white figure appear in the sky, that powerful sword momentum, Haoran sword qi, made the disciples of the two sects overjoyed, "It's my Terran monk!"

And Ye Li'er, looking at that figure, only felt extremely familiar. (To be continued......)
