"Good boy, you have actually comprehended the three powers of heaven and earth: thunder, water spirit, and fire spirit. No wonder you have no fear, but let's see how far you can fight with me. The ancient sword demon Hong Yuanfeng said in some surprise.

"If you do too much injustice, you will kill yourself, even if I am not completely sure of winning, but I must give it a go!" Duan Yu's attitude was quite resolute, and he suddenly said awe-inspiringly.

The sword light and sword shadow flickered, filling the void with a radius of hundreds of zhang, and the torrential rain also seemed to disappear between heaven and earth, because only the sword light and sword shadow were the most gorgeous.

The surrounding peaks and cliffs were constantly blown down by the spread of sword qi and swords, and the rubble burst out.

Duan Yu fused the three powers of heaven and earth to exert them, and his power increased, which also made the ancient sword demon Hong Yuanfeng feel threatened.

Hong Yuanfeng didn't dare to be careless, so he seriously used the ancient sword secret technique, and while fighting, he also carefully perceived Duan Yu's martial arts moves, hoping to find some secrets about the Immortal Taixuan Sutra from Duan Yu's martial arts.

After a long while, the power of the ancient sword secret technique was still above Duan Yu's "Sword Double Kill, Nine Nine Eighty-One Style", and the Qingfeng Slashing Sword held in Duan Yu's left hand was immediately blown away by the ancient sword.

Duan Yu also flew out upside down, and he used a flowing harrier to turn over in mid-air, and stabilized his body.

The Breeze Slash Knife is far away, making it difficult to pick it up.

Duan Yu stood with his sword in his right hand, some blood was already spilling from the corner of his mouth, he was indeed injured.

"Hmph, the pearl of rice grains, dare to compete with Haoyue, suffer death, boy!" Hong Yuanfeng, the ancient sword demon, sneered, and immediately held the ancient sword in both hands. Volleyed over, a huge sword aura. Just like a heavenly sword, slashing down fiercely.

Duan Yu's left index middle finger. Pure energy is condensed, with lightning as thin as a hair swirling around, as well as flames and frost.

Moreover, Duan Yu understood that it was now a critical moment of life and death, and he had also used the unique star energy formed by cultivating the Immortal Taixuan Sutra for most of the past half a year.

It was too late, it was too fast, and in this instant, the ancient sword demon Hong Yuanfeng had already leaped in front of Duan Yu in the air.

"Silent Finger!" Duan Yu immediately used the trick of fusing the three sharp fingering techniques of "Spirit Rhino One Finger, One Yang Finger and Mixed Yuan Thunderbolt Finger". Accompanied by the sound of wind and thunder, there is also the power of the stars.

A crisp sound of metal shattering sounded, but it was Hong Yuanfeng's trick that was difficult to change halfway, and he didn't have time to resist this finger with the ancient sword, so that the finger pierced Hong Yuanfeng's armor.

Immediately after that, the finger penetrated the heart of the ancient sword demon Hong Yuanfeng, but it was a pity that for a demon like him, his heart was not critical.

Once in the battle of the ruins of the Aoki City Lord's Mansion, Duan Yu took the opportunity to slash a sword on his head, but he didn't take his life.

"What a sharp finger. I actually shattered my Xuantian Demon Slaying Armor, and only by killing you and retrieving the Immortal Taixuan Sutra can I make up for my loss. Hong Yuanfeng felt sorry for the damage to his armor. It can be seen that it is not a big deal for the heart to receive this finger.

In the blink of an eye. Hong Yuanfeng had already flown in front of Duan Yu, and at this moment, he had used the most ferocious tricks in the ancient sword secret technique. It's all a life-and-death fight.

The evil qi of the human muscles and bones and the sword qi of the ancient sword completely fused and complemented each other. Coming from many very strange angles, Duan Yu was difficult to resist.

He dodged with Ling Bo for a while, but the ancient sword demon Hong Yuanfeng completely stimulated the battle intent, as if he was going crazy.

In close combat, Duan Yu used to be good at many tricks, but it was inconvenient to use them. Tricks such as the Six-Vein Divine Sword, the Mighty King Kong Palm, and the Shaolin Dragon Claw Hand were actually useless when dealing with a powerful opponent like the Ancient Sword Demon Hong Yuanfeng.

"Suffer death, the ancient sword is one!" Hong Yuanfeng shouted, and a demon phantom with a height of dozens of zhang was summoned behind him, and he also held an ancient sword in his hand, but it was formed by shadows, which looked breathtaking.

In the surrounding void, hundreds of ancient swords also appeared out of thin air, these were all sword qi, not real swords.

Under Hong Yuanfeng's sword intent control, the sword qi of these hundred ancient swords quickly converged towards the giant sword in the hand of the demon phantom, and then the giant sword slashed towards Duan Yu. At the same time, Hong Yuanfeng also flew like a frightening fly, and the ancient sword stabbed at Duan Yu's throat.

"Even if I run away at full speed, I will definitely not be able to avoid this sword qi. Duan Yu knew it in his heart.

Over the years, many life-and-death battles have made Duan Yu's grasp of the battle situation reach an extremely clever point.

"Only by striking with all my strength to resist Hong Yuanfeng's move head-on, otherwise I will have absolutely no chance of survival. Duan Yu admonished himself in his heart.

So, Duan Yu held the Demon Breaking Sword, burst out with the power of heaven and earth, and secretly used the trick mental method taught by the ancient demon beast Xuanwu last year, looking up to the sky and shouting: "Xuanwu Desperate Slash"!

Suddenly, Duan Yu spun up, and his sword aura soared into the sky, a whirlpool-shaped sword qi that was more than five hundred zhang long, and its power was not under the giant sword held by the demon shadow summoned by the ancient sword demon Hong Yuanfeng.

This is the purest head-to-head match, with no extra fancy tricks to speak of.

Then, Duan Yu flew out upside down, and he felt a piercing pain in his heart, because the attack of the ancient sword demon Hong Yuanfeng had indeed caused a lot of damage to Duan Yu's heart. The opponent's sword qi bombardment made Duan Yu's whole person feel as painful as if he had been struck by lightning.

Without any hesitation, Duan Yu understood his current state, and he couldn't continue to stay and fight against Hong Yuanfeng, otherwise there was only a dead end.

As a result, Duan Yu's back formed the wings of the Fire Phoenix with the power of the rich fire spirit, and then flew quickly backwards, and with the Escape Wind Technique, the speed was extremely fast.

Behind is a cliff, Duan Yu jumped down without hindrance, because of the wings of the fire phoenix, Duan Yu would not be as tragic as other cliff falls.

In the process of this flight, Duan Yu's injuries worsened further, because in the blow just now, there was too much demonic energy and evil qi in the ancient sword, and if it was other Void Realm martial artists, it was estimated that it would collapse directly.

Fortunately, Duan Yu's background is extremely profound, and Cheng Dù's injuries can still be supported hard.

At this time, the ancient sword demon Hong Yuanfeng's footsteps staggered, and it took more than a dozen steps backwards to stabilize his body, piercing the ancient sword to the ground, and sighed deeply: "What a Duan Yu, the strength is almost catching up with me." Is the Immortal Taixuan Sutra really so magical? I will definitely get it, Duan Yu, you just wait. ”

With that, Hong Yuanfeng's tall figure disappeared into the rain curtain.

And Duan Yu flew a long distance in the void before he found a remote bamboo forest, landed down, converged the wings of the fire phoenix, and prepared to heal. (To be continued......)
