The sword mouth looked at each other's eyes, Duan Heyu suddenly calmed down, he was anxious to think about how to use the unity of human and sword, at this moment he realized that there was a sword in his eyes, and there were eyes in the sword, he issued a move in his heart, and the combination of human and sword flashed like a meteor in an instant, and he actually synthesized a sword qi and pierced through... When the time comes, the scene in front of him will deeply shock him at one time, the room is full of jewels and rare night pearls, gold and silver plus more than a hundred swords emit a brilliant light, even if it is not lit, the entire stone room is illuminated clearly.

Duan Heyu approached the sword gong position and found that each sword had one thing in common was that it was broken and put together, and there was a painting next to the sword, which described how the owner of the sword was killed in seconds. Undoubtedly, this is the trophy that Dugu Ao seized from the head of the sect when he challenged the various factions in the rivers and lakes, in addition to the swords of the famous heroes from all walks of life, it can be thought that Dugu was arrogant and domineering thirty years ago, and it also made the factions of the rivers and lakes frightened, and they didn't even dare to come up with the idea of revenge.

Among all these top-notch and valuable swords, there is one that stands out at the forefront... Duan Heyu saw that it was written next to it "Dugu Heavenly Demon Sword", this sword was cast by flying stones outside the sky, weighing seven catties and two taels to absorb the essence of heaven and earth, the sun and the moon, the old man was invincible in the world, and all the swords and knives in the world were as easy to break as muddy tofu when compared with them. With this Dugu Heavenly Demon Sword, it swept the world in the first ten years... For the next ten years, no one came to fight, but they sought defeat. Duan Heyu blurted out: Wow, this Dugutian Demon Sword is really different, and at first glance, he knew that it was not a mortal thing, he happily lifted the sword to watch it, but unexpectedly, the tip of the sword emitted a light, and the place where the sword light fell was exactly where the mechanism was opened, and the two sides of the stone room were removed to reveal seventy-two stone tablets, each stone tablet was cast with a sentence, Duan Heyu exclaimed: Demon Sword Formula.

Great, I found the magic sword formula that the master asked me to find, and he couldn't help but secretly admire the craftsman who built the secret room design mechanism, if he hadn't inadvertently played with the Heavenly Demon Sword, how could he activate the mechanism... It seems that it all is fate.

When Duan Heyu was feeling that everything was caused by the opening of the mechanism, there was a tall and exquisite image refracted from the Heavenly Demon Sword in the secret room: Young man, congratulations on entering the secret room to open the mechanism, do you know that the light emitted by the tip of the sword to open the mechanism is actually opened by the power of the hundred years left by the power in your body and the old lady's sword when the sword is united, I believe that your skill must also be more than a hundred years, you and the old man are destined to enter here, seventy-two stone tablets are engraved with seventy-two formulas of the Heavenly Demon Sword Spectrum, and the stone tablets behind the formula are engraved with the Heavenly Demon Sword moves, you first learn the mantra and then practice the moves with the Heavenly Demon Sword。

Duan Heyu was surprised and said: You are Dugu Ao's uncle, the disciple Duan Heyu visited the master, and the master was bowed three times by the disciple, and knelt down and kowtowed three times sincerely. Dugu Ao's voice responded: You practice your sword quickly, and I will guide you by the side.

The disciples obeyed. Duan Heyu calmed down, holding the Heavenly Demon Sword in his hand, and saw that the mantra of the first move "one sword out of the sheath" was tangible and invisible, and his heart was inspired, and the sword qi followed everywhere in the move, and after practicing a move, the stone tablet was destroyed... Duan Heyu was stunned and said: "Uncle, the disciple is not intentional, I am practicing according to the moves and mantras, and I don't know that the stone tablet will be damaged."

Dugu Ao's voice laughed and said: It turns out that your kid has learned the Heavenly Demon Sword moves, very good, very good, you don't have to worry that these moves and mantras engraved on the stone tablet will be shattered with the sword qi of each move after you practice one move.

Duan Heyu was relieved: Uncle Bing, the disciple's Heavenly Demon Sword move was passed down by his mentor Dugu Immortal.

Dugu Ao replied in a voice: The old man has already guessed, in this world, I only passed on the moves to my own brother, young man, you should concentrate on practicing swords now. The first forty moves of the Heavenly Demon Sword are mainly based on breaking others, and the latter moves are based on sword qi as the core, and the power is infinite. Therefore, back then, the old man only passed on the moves, not the formulas, and set up this secret room, hoping that the younger brother could train a successor to inherit the Heavenly Demon Sword and find it...... The old man has waited too long for this day.

The power of the Heavenly Demon Sword's moves with the mantra is simply too ruthless, the first forty moves break the sword style, the water is powerful and powerful in form, the wind is weak and light and terrifying, and the qi is invisible and invincible...... Duan Heyu practiced the thirty-two moves later, and the sword turned into a sword, and his heart turned into a sword from the four elephants, and he condensed his mind with the force caused by his will, and his mind was out of the sword qi form, and he was also reinvented by thinking and acting, and everything was indestructible or even ...... The sword qi of the trick followed, and the stone tablets erected with flying stones outside the sky were smashed by the sword qi like cutting tofu, and when the last move was practiced, the mantra above was that there was a sword heart in the eye, and the eyes in the sword were one...
