South China Sea.

At the end of the sky, the boundless sea, the sea surface is rolling, the waves are magnificent, the sky is full of dark clouds, the stars are covered, the thunder is rolling, the lightning is like a blooming flower, blooming in the gap between the clouds, the time is hidden, and the shadow is sufficient.

Two shadows, one black and one white, shuttle between the dark clouds, like a meteor in the sky, like a butterfly, chasing each other, the brilliance flashes, shining.

These two have been fighting on the top of the South China Sea for more than three days, and at this time they are close to running out of mana and running out of oil, but they are still indistinguishable from each other.

The man in white, nearly eighty years old, has a white beard and hair, but his skin is like a jade, and his skin is better than a baby; the man in black is a man in black clothes and black robes, entangled in black light, unable to see his face clearly, holding a four-foot long sword, the width of the sword is two fingers, and the faint divine light is flashing, and the agility is incomparable. He held this sword, entangled with the man in white, and did not fall behind at all, which shows that this sword is absolutely extraordinary.

The two chased and fought fiercely, and for a long time, they still didn't know the winner.

Suddenly, the man in black shook his long sword, and his figure turned into a black light, chasing after him, blocking the way of the man in white, and the two faced each other from afar.

"White-eyed ancestor, your Taoist spells, boasting of great powers, extremely powerful, and ever-changing, are the authentic Immortal Dao......, how can you face my little 'Demon Dao Demon', but you are so muddy and watery, more than capable of escaping, but you are powerless to attack?" The man in black sneered and said, "Could it be that you have a Mahayana period of cultivation, but you have already paid for it?"

The white-eyed ancestor turned pale, and interrupted in a deep voice: "Old man black, don't be self-righteous, with my white-eyed ancestor for one day, your demon path will never win." ”

The old man sneered and said, "In this case, why do you only care about running for your life and don't dare to fight me head-on? Now, you and I are both standing at the peak of the two realms of immortals and demons, and we can represent the vast world, countless beings who cultivate immortals and demons. Heh, it turns out that the orthodox cultivation of immortals is how to escape for your life in a decisive battle, isn't it ridiculous?"

"Black old man, Hugh is talking nonsense, today, my white eyebrows want to see and understand, why are you so arrogant. ”

The white-eyed ancestor was extremely angry, his eyes were stunned, his hands pinched again and again, and in an instant, countless magic tricks were played. Suddenly, I saw a flash in the dark sky, and dark clouds rolled under my feet, going upstream, rising into the sky, turning into a white dragon in a moment, circling and roaring, and rushing to the black old man in front of him.

In the roar, the white dragon's body suddenly burned with fiery red light, changing in an instant, sometimes angry dragon, sometimes turning into a tiger, in an instant, it was already close, the momentum was mighty, and it had the potential to destroy heaven and earth.

The old man sneered, his expression was calm, the four-foot long sword in his hand shook, and flew out of his hand, turning into a streamer of light, with endless changes.

'Boom!'

The white dragon and the streamer collided in pairs, the heavens and the earth shook, the rolling dark clouds, instantly dispersed, and the sea under their feet was turbulent, like a bottomless abyss, roaring and roaring.

The flying sword, broken into several knots in an instant, fell into the bottomless sea, and offset the white dragon.

"Tribulation Period!" The white-eyed ancestor was shocked, retreated again and again, his face changed even more, and shouted: "Old man Heisha, you are already a cultivator in the Tribulation Period, why shouldn't you go away with the Nine Days of Thunder Tribulation? With your cultivation, you can force yourself to stay in the world, and you can know that it will change the yin and yang of heaven and earth, and the order of north and south." You shameless monster, you change your life against the sky, it is really shameless, and you will be punished by heaven!"

The old man sneered and said: "Yin and Yang are determined by things, the high-grade immortal cultivation technique, the Taoist orthodox immortal cultivation technique, the secret technique of the Erji Sect that is not passed on, hum, the power is nothing more than that." White-eyed Ancestor, do you see if my Heavenly Killing Technique is stronger than your Yin and Yang Transformation Determination? That's right, I have already reached the cultivation of the Tribulation Period, and I shouldn't be the Nine Heavens Thunder Tribulation, just because I don't want to, the Heavenly Dao, the Orthodox Immortal Dao, what can I do? As for shamelessness or not...... I think, shameless than your behavior of snatching your brother's wife, right? haha......"

After saying that, his hands played thousands of magic tricks one after another, and the heavens and the earth suddenly changed color, and a bloody and explosive aura surged out.

"Yin and Yang are infinite, Fahai is infinite, time and space are infinite, and the Demon Dao is infinite!"

The old man shouted loudly, and four Wuji in a row suddenly sacrificed a thing, and it rose.

This thing, like a circle, round and boundless, blue like the sea, on it countless fine lines, like the jerky and small words, and like thousands of Taoist recipes, connected into a string, row by row, like a bright pearl, slowly swimming back and forth, shining. Although this pattern is small, it is all-encompassing, covering heaven and earth, just like countless heavens, countless earths, and countless time and space, all of which are all in one mirror, forming these countless small lines, which are infinitely mysterious.

As soon as this mirror appeared, the surrounding space began to wail and struggle, beating and beating, and the sound of breaking seemed to collapse at any time.

The white-eyed ancestor's face changed drastically again, and he exclaimed in surprise, "One of the top ten superb immortal weapons, Yin and Yang Infinite Realm!!...... Okay, okay! Old man Black, in order to defeat me, you have exhausted all the tricks, but it is not yet known who will kill the deer!"

He laughed in shock, but he didn't dare to be careless at all, and he also hit something in an instant. This thing is not a magic weapon of a flying sword, but a three-legged strange bird, with three legs in front and one in the back, flaming red feathers, and a short and white beak.

The three-legged strange bird was urged by the mana of the white-eyed ancestor, as soon as it came into contact with the air, it rose against the storm, and in a moment, it had risen into a big bird several feet high, and the fiery red feathers turned into ten thousand degrees of real fire, swallowing and spitting, and in the sound of smacking, it actually ignited the surrounding air and the sea under its feet.

"Squeak!"

The three-legged monster bird raised its head to the sky and let out a long roar, with the long whistle, a fiery red fluctuation, shooting out in all directions, and the pitch-black space that was beating like a rhythm could not withstand such a high temperature. An incomparable force shot through, and everywhere it passed, time and space flew and slowly fell.

The old man's tone changed in shock, and he said: "One of the twenty-eight innate spirit treasures, the three-legged red bird Bi Yuewu! Good, good, good! In my lifetime, I can see the divine power of the innate spirit treasure, the true immortal, even if I die, it is worth it!"

After that, he hurriedly urged the huge and incomparable mana of the Tribulation Period, and the Yin and Yang Infinite Realm, one of the top ten peerless immortal artifacts in ancient times, instantly soared, and in a moment, a whirlpool black hole with a diameter of several battles was formed above his head, and the black hole rolled and rotated, and the infinite attraction power came out of it, and suddenly the wind and clouds changed color, and the wind suddenly rose. The dark clouds, the air, the rolling sea water under your feet, the slowly approaching Wandu True Fire, the empty space around you, pulled by the infinite attraction force, like a muddy swamp, actually slowly moved towards the center of the whirlpool, as if it was about to be absorbed by the rolling whirlpool.

"Old man Black, do you want to destroy this heaven and earth? Hmph, shameless monster, don't you hurry up and stop Dao Ye!"

The white-eyed ancestor shouted, his hand led the yin and yang to turn into a matter, the three-legged red bird Bi Yuewu, several feet high, the flames around him were even more three, and he looked up to the sky again and roared, suddenly turned into a red ray, rushed to the Yin and Yang Infinite Realm, and the red light pierced the sky and flashed.

"Come on, win or lose in one fell swoop!"

The old man shouted loudly, and dealt with it with all his might, and the black light around his body was swallowed, like a ghost outside the sky, devouring the starry sky.

"Buzz!!"

"Boom!!"

A muffled sound and a bang burst out at the same time, shaking the heavens and the earth. Immediately, there was a dead silence between heaven and earth. Dark clouds rolled, sea water shot out, and storms and rain fell violently...... Everything is so explosive, everything is so peaceful.

The black and white two people face each other from afar, like two lonely fallen leaves in a storm, the light is dim, swaying and swaying, as if they will fall into the abyss in an instant, and there will be no return.

"Ahem...... The innate spirit treasure Bi Yuewu really lives up to its reputation, and I am so defeated that I am convinced!" When the wind and clouds calmed down, the old man coughed violently a few times and said, "But remember, I am not defeated in the hands of your white-eyed ancestor, nor am I defeated in the so-called Immortal Dao Authenticity, but ...... Defeated at the hands of Bi Yuewu. ”

The white-eyed ancestor was embarrassed, opened his mouth and spit out a few mouthfuls of blood, and said weakly: "Black old man, since you have been defeated, the Demon Dao has been extinguished from now on, and in the Fangtian world, under the whole world, there is only my Immortal Dao authentic." ”

The black old man was crumbling, a striking wound on his chest spurted out gurgling blood, and the Yin and Yang Infinite Realm, one of the top ten superb immortal weapons, had already been shattered into two, and he was holding it tightly in his hands, looking dull and unremarkable.

"What is a demon, what is an immortal?" The old man in black was like a withered leaf, his eyes closed, and he slowly fell into the bottomless abyss-like sea, whispering to himself, turning into a mournful roar, "What is a demon!

"What is a !!?"

"What is a fairy !!?"

The mournful roar pierced the sky, tearing the heart and lungs, as if it had become an incomprehensible proposition, rushing straight into the sky, as if it was preaching to the ethereal preaching above the nine heavens, and as if it was an old man, unwilling to shout and roar before he died.

The old man of the black sinister finally fell into the deep sea with the Yin and Yang Infinite Realm, but between heaven and earth, in the heart of the white-eyed ancestor, his heart-rending cry before death still floated.

What is a demon?

...............

Three days later, Wanxian Island.

The white-eyed ancestor was half lying on the beach in embarrassment, holding the three-legged red bird Bi Yuewu solemnly with both hands. In the last battle, Bi Yuewu was also seriously injured, recovering to the size of a palm, his wings were broken, and he had no ability to fly again. It was lying on the palm of the white-eyed ancestor's hand, its eyes drooping, like a chicken in the water, looking listless.

The white-eyed ancestor smiled bitterly and said, "The Yin and Yang Infinite Realm, one of the top ten superb immortal weapons, really lives up to its reputation and is extremely powerful. I joined forces with you, and although I finally defeated it along with the old man in black, his dying blow also cut off the vitality of you and me, and I have no possibility of living again. ”

"Today, I will use the only remaining immortal power to help you heal, although it can't make you heal, but it can also make your life worry-free, and after that, you will go to the Wuji Mountain Erji Sect. That's where I learned from me, and it's also the Orthodox Dao Sect of the Immortal Dao, and you're safe and secure there. ”

"Although I haven't returned to the Erji Sect for nearly a thousand years, I am a teacher for one day and a father for life, and when I die, I want to see her again. However, I'm afraid I won't be able to survive that time, so I can only ask you, old friend, to go back and take a look for me, and then, you can find a blessed place where no one is in the world, cultivate alone, and one day, ascend to the Tao, and forget about my heart. ”

"The Demon Dao Ancestor is deceased, the Demon Sect is a evil seed, when he learns this news, he will definitely stain the world with blood and avenge it, and the two immortals and demons who have calmed down for thousands of years will definitely set off another bloody storm......

He looked at the endless blue sky, his eyes became hollow, and then slowly collapsed, and whispered, "What is an immortal?

"What is an immortal, and what is a demon?"

This sentence slowly floated between heaven and earth.
