Qi Feiyu gritted his teeth, took a deep breath, swung the Zhentian Sword, and split the sword mark that had been split before, once again, so that it was three zhang apart before he withdrew the Zhentian Sword and turned to look at the Nether Dog.

He's decided to fight the Nether Dog alone, even if he dies......!

Qi Feiyu's eyes suddenly darkened, if he died, he would not be able to complete what Yan Huang had entrusted him. Although the Tai Chi swordsmanship has gradually become familiar, it is far from achieving the goal he wants.

It's a pity......

Qi Feiyu sighed, if he was lucky enough not to die, he could still continue to see the Taiji swordsmanship spread, but if he died......

Now, I can only pray that he will survive this battle.

When Qi Feiyu finished thinking about this, his expression became resolute, and the Zhentian Sword Xuan Soul suddenly appeared behind him, and the eight qi on the sword flowed in a dense manner, and it was extremely quiet.

But at this time, a strange scene appeared, and the eight aura on the Zhentian Sword suddenly became irritable, and it turned wildly uncontrollably.

In just a few dozen breaths, the eight breaths were like eight sharp long swords, cutting through the clothes on Qi Feiyu's body, revealing the skin full of sword marks.

Qi Feiyu's expression was calm, as if he had not cut his own skin, but he clenched his fists tightly, and his eyes were extremely sharp and staring at the Nether Dog.

The Nether Dog bared its sharp fangs and responded viciously to Qi Feiyu, its two front paws digging into the ground as if it was about to attack.

But the Nether Dog didn't dare to attack rashly at this time, first, it didn't have much strength left, and second, Qi Feiyu's current aura was too violent, and the sharp aura had already broken all the surrounding voids. If it attacks at this time, it is very likely to die in Huangquan.

As the sword qi continued to cut his body, Qi Feiyu revealed countless blood, spilling it all over the ground, reflecting the ground in blood red. With a painful roar, Qi Feiyu had no uninjured place on his body at this time, and the sword marks were densely covered all over his body.

But the more this happened, the more Qi Feiyu's body exuded a cold and terrifying aura, as if he had just returned from the sea of blood, making the Nether Dog's hair stand on end.

At this time, Qi Feiyu suddenly made a move, but the object of his move was not the ghost dog, but himself!

I saw that Qi Feiyu held the Zhentian Sword Xuan Soul on his back with his backhand, and then plunged the tip of the sword into his heart.

The forbidden occult technique of the Golden Academy, Shura slash!

Cut off the body and mind, cut off life and death, cut everything!

Shura, killing!

Borrow the killing qi to forcibly improve the realm cultivation.

Nine products, Xuanzun one, two, three, four, until Xuanzun nine products!

Qi Feiyu's breath continued to rise, and he reached the ninth rank of Xuanzun in an instant, but after reaching the ninth rank of Xuanzun, his breath did not stop, but continued to climb!

From all over the underworld, bits of red light began to emerge, and these red lights were countless, and they came from the killing aura that remained in the underworld.

The killing qi almost condensed into substance, and instantly poured into Qi Feiyu's body, with the help of these killing qi.

Xuansheng Yipin, broken!

But the killing qi did not stop pouring in, and continued to pour into Qi Feiyu's body continuously, until there was no trace of killing qi in the underworld.

Xuansheng four products!

This is Qi Feiyu's cultivation realm at this time.

You must know that the cultivation of the Xuanying Realm Xuanzhi ascended to the sky one step at a time, if it weren't for the fact that the killing qi remaining in the underworld was large enough, Qi Feiyu would never have reached the four grades of the Xuansheng, at most the Xuansheng one grade, it would have been the limit.

When Qi Feiyu's cultivation "broke through" to the fourth rank of Xuan Sheng, there was obvious fear in the eyes of the Nether Dog, and there was a gap between Xuan Sheng and Xuan Zun.

For a while, the Nether Dog began to have the intention of retreating, although Qi Feiyu relied on the forbidden Xuan Technique to break through, and he was unable to exert the Xuan Sheng's Xuan Qi Law. But in terms of power alone, it has completely crushed it.

"Feiyu, you ......" Looking at Qi Feiyu, who had already run the Shura Slash and turned into Shura, the dean suddenly didn't know where to speak. As the dean, of course, he knew that once the Shura Slash was in operation, it would not stop easily.

Even if it is the Burning Heart Flame and the Eternal Evergreen, it is not as domineering as Shura's slashing.

Shura Slash, communicate with Shura Dao, borrow the killing qi, as long as there is enough killing qi, the stronger the Shura slash can improve. On the contrary, the side effects caused by the Shura Slash are greater.

Fei Yu's improved strength at this time was far beyond the limit of what he could bear.

If Shura Slash stops here, it will not only disappoint Feiyu's intentions, but also make Feiyu's sacrifice in vain.

Thinking of this, the dean couldn't help but sigh, and then fell into deep remorse, he hated, his strength was not strong, and he couldn't stop the Nether Dog. He hated, because of his "playfulness", let five teachers come to look for him, otherwise such a thing would not have happened.

First, Zhan Tao was trapped in the underworld, then Zhou He ran the Heart Burning Flame, causing him to fall unconscious, and then Qiu Yue helped him resist the Nether Dog's killing moves, and was seriously injured. In the end, even Qi Feiyu also ran the Golden Academy's forbidden Xuanji Shura Slash.

But what's the use of saying this now, what he can do now is to keep praying that Qi Feiyu can still survive after the Shura slash is over.

After thinking about this, the dean immediately closed his eyes and used the Xuan Qi to repair the tendons and veins in his body. The purpose of their coming this time is to rescue Zhan Tao, if Qi Feiyu... If then, only he can save Zhan Tao.

Seeing that the Nether Dog wanted to escape, Qi Feiyu instantly pulled out the Zhentian Sword, which is strange to say, after Qi Feiyu pulled out the Zhentian Sword, the place where he was inserted by the Zhentian Sword was surprisingly not a drop of blood flowed, and not even a wound was left.

But that's not the point.

The point is that Qi Feiyu reversely grasped the Zhentian Sword, and then threw it at the Nether Dog like a spear.

The Zhentian Sword flew straight out of Qi Feiyu's hand, but just as it flew into the air, a strange ripple suddenly flashed in the air, and the Zhentian Sword disappeared immediately.

Nether Dog's eyes widened, and he kept looking left and right for the trace of the Zhentian Sword, but he found nothing.

But at this moment, the Nether Dog's hair suddenly stood on end, and it felt that it was locked by a fierce aura, and wherever it fled, this aura would follow.

Gradually, not far from the Nether Dog, a ripple suddenly appeared, and this ripple appeared silently, and the tip of a golden long sword poked out of this ripple.

This is the Zhentian Sword!

Qi Feiyu, the fourth rank of the "Xuan Sheng", showed his strong strength at the moment as soon as he made a move, and at the same time, he also showed how powerful the gap between him and the Nether Dog was now.

There is no way to retreat, or rather, there is no way to retreat!

The heart roared unwillingly, and the voice drifted far and wide through the underworld, but there was surprisingly no echo.

Just as the tip of the Zhentian Sword was pressed against the forehead and eyebrows of the Nether Dog, an ethereal sigh suddenly came.

"Hey. ”

This sigh contains a lot of emotions, including loss, shock, admiration, unbearability, and other complex emotions, but it is contained in this sigh.

"Quiet. ”

There was a clear cry again, and I saw that the Zhentian Sword stopped between the eyebrows of the Nether Dog, and could no longer go deeper for half a minute.

When the Nether Dog heard this, he bowed his proud head into the corridor and bowed respectfully three times.

"Who!" Qi Feiyu said hoarsely, directly recalling the Zhentian Sword, staring sharply at the inside of the corridor.

"Nether, stand aside. ”

The voice gradually became clear, it was a young man's voice, but this voice made people feel very vicissitudes. The vicissitudes of life are so vicissitudes that you can feel the taste of time.

The Nether Dog bowed again, and its body immediately became illusory, and the next moment it was about to disappear.

But Qi Feiyu was willing to let go of the Nether Dog so easily, and the index finger and middle finger of his right hand were together, and he poked at the Nether Dog.

A cold light instantly knocked down the Nether Dog's body, completely piercing its body.

The Nether Dog let out a painful wail, then dissolved into a cloud of black mist and disappeared into the air.

"Come in. The man didn't care, and directly called Qi Feiyu in. At the same time, the road lights suddenly lit up, and these lights were made of soul fire.

The lights illuminated the Yongdao and the entire underworld, and Qi Feiyu and the dean saw clearly that at the end of the Yongdao, there was a very old and dilapidated palace.

According to the experience of the dean, the dean could easily see that this palace had existed for at least 100,000 years.

The palace is extremely dilapidated, and the wall on the left side has collapsed directly, looking crumbling, and it can't help the wind and rain at all.

Fortunately, there is neither wind nor rain in the underworld, so this palace can survive.

Qi Feiyu put away the Zhentian Sword, there was no fear on his face, and he walked towards the palace step by step, he wanted to see what kind of sacredness could drink back the Nether Dog.

"Come in too. ”

The man made another sound, and then three gray breaths floated out from the depths of the palace and submerged into the bodies of the dean, Zhou He, and Qiu Yue.

After these three gray breaths submerged into the dean's body, the dean could clearly feel that an extremely cold and extremely gentle aura flowed in his veins.

After the circulation, the tendons and veins that were originally broken were quickly repaired by themselves, and the repair speed was extremely fast, and the tendons and veins of the whole body were repaired in the blink of an eye.

Qiu Yue on the side, after spitting out a mouthful of bruises with black mist, her face gradually recovered. Zhou He woke up directly from the coma.

The three of them looked at the palace with shocked faces, thinking to themselves, what kind of existence was the people in the palace, who could completely heal their injuries within the time they were recovered. And you know, the man didn't even show his face.

With deep doubts, the three of them supported each other and walked towards the palace with Qi Feiyu.

The closer they got to the palace, the more they could feel that from inside the palace, there was a strong aura of reincarnation.

There is only one person who can have such a huge aura of reincarnation, and that person is the legendary king of the underworld.

Hades!
