Ancient books record: the sword, open double edge, straight head point, horizontal and vertical can hurt people, stabbing can penetrate the armor, dangerous and abnormal, born to kill! The swordsmanship and sword tricks in the world are strange and unpredictable, and people yearn to have a long sword, a sword trick, and from then on they will be happy to enmity and revenge, and fight the sword world, because this is a world where the sword is respected.

According to ancient legends, Nuwa used the essence of the multicolored stone to endow it with the strange iron in the center of the earth, and used the Nine Heavens Holy Flame to cast a peerless divine weapon, called the Xuanyuan Sword!

Since then, Nuwa has held the Xuanyuan Sword to sweep away the injustices in the world, and has been admired by all living beings, but 6,000 years ago, Nuwa suddenly disappeared without news, this is the world's largest mystery!

The giant wheel of history rolls forward, 5,000 years ago, the heavenly demon was born, with strong strength and cultivation through the sky, coupled with a bit of strategy, became the master of heaven and earth, ruling the world for 2,000 years!

Three thousand years ago, the Heavenly Demon tried to use the blood of all living beings in the world to help him accomplish the great cause of eternal life for his own selfishness.

The final result was, of course, that evil was invincible, and the great god of Pangu had the last laugh! I wanted to completely wipe out the heavenly demons, but the heavenly demons had cultivated into an immortal and immortal body, and there was no more power in the world to kill them, for the peace of the world, the great god of Pangu had to seal it in the outer heavens! The world that had suffered a lot finally had a rare respite, and slowly repaired the mess left by the heavenly demons! However, a thousand years later, the water god Gonggong and the fire god Zhurong became the overlords of the battle for heaven and earth, and a tragic war broke out.

This protracted and vicious battle ended with the defeat of the water god, and the co-workers were unwilling to surrender, and in a fit of anger, their heads could not touch Zhou Xianshan, which brought unprecedented disasters! Not only did the heavenly pillar collapse, causing the sky to fall northwest and the earth to the southeast, but also to change the luck of heaven and earth, so that the seal of the outer heaven was loosened, and the heavenly demon took this opportunity to poke out a big hole in the outer heaven and break the seal!

After regaining his freedom, the Heavenly Demon vented his anger to the fullest, vowing to slaughter all living beings in the world! In the dark, there is its own providence, demons and monsters appear, and there will be people to subdue demons and eliminate demons.

War is cruel and ruthless, especially the war between gods and gods, that kind of scene, that kind of killing and decisive atmosphere, can no longer be described in words, innocents, funeral companions abound, heaven and earth are moved by it!

The Heavenly Demon is the Heavenly Demon, and the cultivation that is proud of the world, and the immortal and immortal body, are like a high mountain that is difficult to overcome! On the other hand, the gods led by Nuwa, although they are pressing step by step, they still fall into the disadvantage!

In order to stop the ambition of the Heavenly Demons, and for the safety of the world, Nuwa and the gods burned their divine power, turned the tide, and used the essence of the Pangu Great Array and the Colorful Stone to re-seal the Heavenly Demons in the outer heavens! Because this battle was so tragic, the history books called it "the battle of annihilation!"

In order to leave hope for the world after the Great War, the great god Nuwa made some living beings out of loess according to the appearance of himself and the gods, and at the same time injected the last trace of life and spiritual power of himself and the gods into these creatures, so that human beings have now stepped onto the stage of history, and Nuwa and the gods have dissipated between heaven and earth!

The Yellow Emperor, the first human being created by the great god Nuwa, inherited the Xuanyuan Sword and the Xuantian Sutra, and at the same time realized various cultivation methods and sword techniques based on the Xuantian Sutra, creating a human cultivation system, so he was respected as the Sword Ancestor by later generations.

After years of penance, the Yellow Emperor finally refined the Xuantian Sutra to the fullest, thinking that he would become the first human being to cultivate to the realm of the Nine Heavens, but it backfired, the last step seemed simple, but in fact it was full of hardships, and after years of hard work, he could not pierce the last layer of window paper, and he had been stagnant in the realm of the Eight Heavens.

After pondering and meditating, Jian Zu thought of a solution, traveled to every corner of the world, looking for the destined people of Huigen, and in more than 100 years, collected the Seven Stars, Haotian, Penglai, Qiankun, Shura, Netherworld, Chi You seven people are disciples, respectively pass down the Taoist system, hoping that these seven people will compete with each other, learn from each other's strengths, and at the same time teach carefully to avoid their previous mistakes and detours in their cultivation, so as to ensure that when these seven people's cultivation reaches the Eight Heavens, they will be more refined than their own realm, and when the time comes, the eight masters and apprentices will join forces to impact the realm of the Nine Heavens, maybe they will get twice the result with half the effort!

Among the seven descendants, Chi You is irritable by nature, easy to kill, but the best talent, the first to break through to the realm of the Eight Heavens! The anxious Chi You asked the Yellow Emperor to be able to comprehend the Xuantian Sutra and the Xuanyuan Sword, in Chi You's opinion, this is understandable, but the Yellow Emperor directly rejected Chi You's request!

The Yellow Emperor naturally has the consideration of the Yellow Emperor, although Chi You is qualified and talented, but his own heirs, not only Chi You, but a bowl of water is level, Xuantian Jing and Xuanyuan Sword are the foundation of heaven and earth, and they cannot be easily revealed.

Chi You was resentful of this, and privately gathered his strength to continuously attack the seal of the Outer Heaven with his own cultivation of the Eight Heavens, in an attempt to gradually weaken the seal and let the Heavenly Demon reappear in the world, so that the Yellow Emperor would sacrifice the Xuanyuan Sword to fight fiercely with the Heavenly Demon!

The Yellow Emperor was furious when he learned about it, but he didn't expect that Chi You would start a big war with Chi You for his own selfishness, regardless of the safety of the world!

The master and the apprentice met each other, which can be described as a great irony! I thought that between the two of them, there would be a point to the end, but who knows, but it was out of control, and Chi You seemed to be enchanted, unusually irritable, not only pressing step by step, but also making fatal moves! The only remaining patience of the Yellow Emperor was slowly exhausted, and a life-and-death battle was officially staged!

Of course, this battle ended with the Yellow Emperor, who was a step up in skill, and Chi You also ended up dead! But the Yellow Emperor also paid the price of serious injuries for this, and what is even more tricky is that the seal of the Outer Heaven has become extremely weak under the attack of Chi You, and the Heavenly Demon may break the seal again at any time, in order to prevent the Heavenly Demon from returning to the world, the Yellow Emperor used the Xuanyuan Sword as the carrier to strengthen the seal of the Outer Heaven with his lifelong cultivation, and in order to prevent future generations from following the practice of Chi You, he used the essence of life to lay down the Four Spirits Zhutian Sword Array, and hid the seal of the Outer Heaven in the void, unless someone cultivates to be able to reach the realm of the Nine Heavens, otherwise, the seal of the Outer Heaven will never appear in the world again！

Soon after, due to the huge consumption and serious injuries, the Sword Ancestor Yellow Emperor came to the end of his life! The Xuanyuan Sword also lost the essence of the colorful stone and the erosion of the Heavenly Demon Qi, and turned into several pieces scattered all over the world, these fragments are the origin of Nuwa's heart, and the Xuantian Sutra was buried in the long river of history with the fall of the Yellow Emperor!

Human beings are not only industrious and intelligent, but also have endless desires and countless ambitions, and all of them yearn for the power to destroy the world and the supreme power! Therefore, where there are people, there will be strife, and where there are people, there will be contradictions! Our story has thus begun!
