The dragon's eye guided Zi Yan to stand in a completely unfamiliar place, and this realm was very different from the bleak continent he lived in, that is, the dragon soaring in the sky!

"...... here?" Zi Yan stood in mid-air, the emptiness under her feet did not make her fall. A moment passed, and the feeling germinated in her heart, and the girl at this time was just an illusory stranger.

The steepled castle towers over the cliffs of the mountains, perfectly blending into the mountains and rivers, as if they were part of a steep mountain.

Beyond the cliff, the beautiful flying dragon hovered in the blue sky, full of freedom in the peace, and the majestic and sacred voice reached Zi Yan's heart, and the voice from the dragon's heart really told her that this was the four heavens - Kosgana, the land of dragons!

This canyon, which is also inhabited by humans, is a paradise where humans and dragons coexist. The earth is gently shone with the beautiful and peaceful sun, the mighty dragon protects humanity with its absolute power, and the people create their favorite things for the wyvern through their skillful hands. The glittering sculptures, each one is so delicate and delicate, as if it is singing the praises of the greatness of the dragon. Ten thousand years of perseverance is like a beautiful dream, recording the beauty and peace of this Kosgana, sweet like pouring into a box, gently transmitted to Ziyan's heart.

----------------------------------------------

However, the sweet dream that surrounds Zi Yan is fleeting, and a battlefield from 10,000 years ago surrounds the girl who is immersed in happiness in the blink of an eye, and countless ruthless chaos soldiers are pouring forward like a mountain of seas, and the wyverns are fighting with all their might, and the flames that spit out from their mouths represent promises and oaths, burning endless invaders.

Yes, dragons, in this four-dimensional world, are such powerful beings, an ancient mission is calling them, protect the human beings of the four heavens! Protect this land with countless good memories! Endless battles have lasted for hundreds, millennia, and ten thousand years! How many chaos has been wiped out, and how many flying dragons have died in wailing.

But in those days, dragons have always kept their promises to protect human beings, but because of the great differences and unknowns between them, they are like an invisible high ice wall, separating two creatures that coexist with each other on the earth, and a thousand words exist in the heart, but they cannot convey it at all.

The mighty dragons know that they are both admired and feared, and they fear that one day, these mysterious and powerful lords will break their promises and abandon their oath to protect the human race, and they fear that one day, the dragons who defy the sky will suddenly spit out flames that burn everything to the ground.

With unease and estrangement, for hundreds of thousands of years, human beings have built towering castles while currying favor with dragons, hoping that these sacred and majestic buildings can become sacred and inviolable territories and comfort the weak and anxious souls in their hearts.

The dragon's wisdom is so supreme and delicate that humans cannot guess it in any way, and when they see the cold walls that humans have built high for self-protection, the dragon knows that small humans do not welcome themselves, and their fear goes far beyond admiration. The benevolent dragons do not blame people, after all, they are so vulnerable, so need to be protected, but they need to be so unavoidable, this is a promise made from the ancient dawn of the world, and the promise is absolutely unshakable! In the face of the chaos that consumes everything, there is nothing human beings can do! Anyway, maybe this kind of peaceful and non-interference days are not bad......

---------------------------------------------

With a hint of sigh and helplessness, the pupils of a black dragon looked at the girl Zi Yan who felt the same way at this time, and followed the black eyes with red flames to look into the distance, it was a huge palace with a diamond shape floating in the air. Under the leadership of the black dragon, all the dragons poured out, and the wings that fluttered in the dark universe seemed to be about to compose an epic battle. In the deepest part of my heart, the voice of the black dragon is pouring out to Zi Yan, my name is Lilian Kosjana, the mother of the great and ancient dragons, since Pangu opened the world, this beautiful fourfold heaven is our place of survival, since the beginning of all souls, the never-ending battlefield has surrounded the chaos and dragons who are chasing the ultimate peace. Hundreds of thousands of years are like a long and dreary dream, for the ultimate pain like eternity, the black dragon has paid countless lives and blood, constantly exploring in this vast universe, time has passed, and now we have finally found the location of the Element of Chaos, in the lonely and dark abyss beyond the fourfold heavenly galaxy, is the origin of this nightmare, and will also be the end of an ancient oath.

It's been too long, it's too tired of my race!Kosjana is desperate to completely destroy the source of chaos, hoping that with the vanishing of chaos and nothingness, the world she loves will be able to say goodbye to heartbreaking darkness forever, and the endless war, please end it quickly!

The Element hidden in the abyss was exposed, and the Element of Chaos, who had fallen into fear and rage, used its greatest power to summon the entire universe of its kind, and in front of the dragon, trillions of Chaos warriors held deadly weapons in their hands, and waited for the battle, this battle was destined to be epic, destined to dye the entire scarred universe.

No one knows how many mountains and seas were destroyed in this cruel battle array, even the gods could not predict it, and even the entire universe was shocked by this duel! The powerful energy hedge made the passage to the other heavens also be torn apart, and the power to destroy the heavens and the earth was actually shattered even the dimension!

The leader of the Black Dragons – Kosjana, rushed into the dark chaos, tens of thousands of chaos soldiers surrounded it, but attracted dozens of beams of light that penetrated the darkness, a fierce explosion was born in response to the light, and another supernova was born, Kosjana, who was galloping in anger in the light, returned to the messy battlefield again, devouring and destroying each other for thousands of years, making both sides exhausted, the leader from chaos and the Holy Mother from the dragon clan reached a consensus, wanting to end this irritating war with a blow.

An incomparably dazzling light came between Kosjana and the Element of Chaos, and when the all-destroying impact came into contact with each other, the terrifying energy gathered in the darkness, and the heavenly punishment issued by the reality god of the growing mass of light, all living beings were reduced to nothing in the sigh and liberation wherever they went. And this bloody light eventually lit up the entire universe, telling the light of sacrifice and heroic poetry, which can be seen by mankind every night, and a beautiful name is sung to future generations - the River of Heaven!

---------------------------------------------------

How many thousands of years have passed, in the land that has been calm and breathing, a cave that pursues rest is accidentally discovered by a kind-hearted young man, exploring the depths of the cave, a black eye with a red light opens, and the dark dragon emits a low roar, trying to drive away the small human with a threatening sound.

But the boy was not afraid of racial barriers, and the dragon was looked at sympathetically by him with a sad face, and the wounds on his body made the boy weep. Such a son of man touched and amazed the scarred Kosgana, and for the first time in eons of time, communication reached the hearts of dragons and humans.

"Aren't you, petite human, afraid of me?"

"Fear, you are so beautiful, how can I be afraid of you, and I can't leave you alone after seeing you, great dragon, let me do something for you, even if it's just by your side!"

How inconceivable it is that the invisible barrier between humans and dragons has been broken by an ignorant teenager, whose humble and inferior language and simple eyes are like a warm flame that heals the seriously injured Dragon Virgin. The huge dragon looked at the small human, but felt shock and love from him, it turned out that this was the feeling of two hearts blending.

In this way, the boy named Ji Yuan took care of the injured Kosgana day after day, and the distance between the old strangeness was gradually narrowing, hundreds of millions of years, it turned out that humans and dragons were able to cherish each other so much, the boy was so in love with Kosgana, and this virgin was so moved.

Thousands of years have passed, in the nourishment of love and the careful care and companionship of the teenager, Kosgana has finally healed! When she soared in the blue sky again, the huge wings invited the boy named Ji Yuan, prostrate on the body of the dragon, and swim in the four seas, their joyful cry was transmitted to the whole mountain and sea, their story passed into the ears of all the dragons and humans, and the love across the race was like a rainbow connecting the hearts of the two races, breaking the ice wall between each other, and composing a song of the fusion of man and dragon, so beautiful, So comfortable and so happy!

----------------------------------------------------

The girl named Ziyan looked at the story that Kosgana showed to her with good wishes, and a kind of hope for happiness was transmitted from Ziyan's gaze.

The Alpine Castle, known as Cosgana, with its exquisite carvings and sacred atmosphere, is a testament to a miraculous history that has survived countless years.

But on a seemingly peaceful afternoon, this sweet poem is overwhelmed by relentless deception and greedy desire. Under the protection of the dragons, the human civilization has grown and strengthened rapidly, and the soul who has the courage to explore is always exploring the ultimate truth, but the drive of desire has blinded the human heart, and I don't know when the human race has discovered the source of the dragon's power, and the cruel eyes are aimed at the eye of the flying dragon who loves mankind incomparably.

A fake invitation, a bloody banquet, is being held in the square of Kosgana, under the common expectation of people and the dragon people, Ji Yuan and the human form of the holy dragon Kosjana entered the palace of marriage, beautiful costumes and flowers decorate the couple who truly love each other, romantic music echoes throughout the sacred hall, simple and kind eyes look at the two newlyweds who are walking hand in hand.

All dragons sincerely hope for the perfect eternity brought about by the union of the lovers. Yet darkness loomed over the continent, the clear sun was covered in dark clouds, the beautiful castle was ravaged by a raging storm, and the sacred temple was bloodied by a merciless spear of chaos!

Kosgana saw Ji Yuan, who was about to become her husband, be pierced through the heart, it turned out that all the beauty was hidden with murderous intent, all the hospitality was just an illusory illusion, and all the blessings were malicious deception. In order to monopolize the eternal and powerful power, human beings single-handedly planned this 10,000-year-long conspiracy, and the spear that killed him was supposed to take away Kosgana's soul, but it was stopped in the chest of his lover impartially, Ji Yuan's final smile in his eyes, as if he was still pouring out the sweet love words, but the flow of blood quickly weakened the fragile life.

The heart of the Mother of Dragons collapsed in an instant! The vows and promises made by eons of time were instantly defiled! The merciless deception is ridiculing the compatriots around her who have been robbed of their lives, what is the matter? Why is humanity so treacherous? Why is it necessary to break that precious peace?!

The power of chaos suppressed Kosjana's body, even if she knew the dragon body again, she still couldn't save innocent lives from killing, looking at Ji Yuan who was still smiling in front of her, she let out a terrifying roar!

The human proudly gouged out her left eye, but the pain was less than one ten-thousandth of her heart, looking at those ugly smiling faces, Kosgana's remaining right eye flowed tears of despair, how ironic and sad it was to be cruelly deceived and destroyed in the city of Kosgana that sang about herself!

However, the sorrow in his heart, but also because of the husband who still believes in human beings until death, thousands of years of dependence, has made Kosjana forget the fragility of the human body, Ji Yuan's death will be more unacceptable than his own disappearance, when the vicious human is about to seize the remaining right eye, Kosjana sent her last petition, she used all her strength, gathered in the only remaining dragon's eye, the eyes are like jewels separated from her body, and in grief and make a contract with her beloved- Live, take my love for you, and escape from this sad and lamentable false place!Go, my husband, go, my Ji Yuan!With the only trust I have in humanity, live well......

Flying sand and stones, bleak autumn and winter, walking in the loss and grief of Ji Yuan, with the eyes of his lover, walking in the long flow of time, looking at the human beings who were unscrupulous because of their power, looking at the dragon clan who was still driven out after being deceived, looking at the four heavens like Nan Ke's dream, the blood and tears in his heart dripped all the time.

How many years have passed, now Ji Yuan is just a dragon knight, the spear in his hand is stained red with blood, he is so hard and desperate to run in the endless war and darkness, this is the only thing he can do for his dead lover, protecting those humans who still really love the dragon clan and those who are full of painful memories in their hearts, the remnants of the small clan, living hard in the dark corners, no matter how sweet the nectar can not drown the brand of betrayal in his heart.

I don't know how long it has been, watching the human beings of the four heavens dominate the entire universe, and the greedy desires are still endless, as if human beings are the terrible chaos, the soul is wailing, the stars are lamenting, and the universe is helpless......

The Element of Chaos, with the body of Kosjana, who had died of heartbreak, finally decided to cross the passage that should not have been crossed in order to avoid the pursuit of the four-dimensional human race.

The ancient ancestors lingered in a world that did not belong to them with despair and gloom, and billions of years of regret piled up like a one-way hourglass, until they finally wanted to return to the fourfold world and fight to the death against the human beings full of deception and malice!

By the coincidence of intertwined fates and chances, Chaos discovers that the qualitative heavens that represent Pangu are also like Kosgana, which are endlessly weakened for the fruitless mislove, and that even the fallen people of the end of the world should be gathered together to send out a music of revenge against the treacherous human beings. The Twelve Nights Watch descended on the double mountains and seas, carrying the sad memories of the past hundreds of millions of years, like a dark cloud flooding the sky above the cloud top, telling the sore heart and burning the anger of mankind!

Zi Yan, who was wet with tears, let go of the trembling fingertips, invisible regret and pain filled the already haggard heart, it turned out that in the distant world, the sadness still continued to write, Zi Yan, who understood everything, and Ji Yuan, who had made up his mind, looked up at the first night watch palace in the air, and the heart still retained the belief and yearning for true love, the beloved was waiting for him at the top of the clouds, and a thousand words were hidden in his heart waiting to be confided......
