There is no need for her sister Xia Yi in the war knife to remind her, Xia Yun has already felt it. Not only is it not lower than the Ghost Emperor's cultivation, but it is also much higher than the Ghost Emperor Quail and Gou Ji that he has encountered.

As the people approached, Xia Yun sat down slowly even if he was on the ground with his sword, even if he mobilized all his cultivation to fight against it.

Even, after the body touched the ground, his chest was sweet for a while, and he opened his mouth and spurted out a mouthful of blood. It just happened to spray all the knives that had been retracted in front of him.

"Ahh

Suddenly from the battle knife, an exclamation from his sister Xia Yi made Xia Yun extremely nervous, but because the pressure was getting stronger and stronger, he couldn't do anything if he wanted to ask.

Poof, poof, two mouthfuls of blood spurted out one after another, and just when Xia Yun really couldn't hold on and was about to pass out, the war knife in his hand suddenly rose out of his hand and flew straight to the person who came. At the same time, Xia Yun heard his sister Xia Yi exclaim again.

"Ahh

It's just that this exclamation is already a little different from the first one, it seems, it seems, that my sister Xia Yi is doing a desperate thing.

As the war knife flew away, as the war knife flew in front of the arrivals, Xia Yun suddenly felt that the pressure around him was decreasing little by little. Finally, Xia Yun could speak.

"Sister, Xia Yi, what's wrong with you?"

I didn't hear my sister's reply, but saw that the sword turned into a dragon again, and fought with the comer.

With the dimness of the original air of the wandering soul, with less blood-colored light, Xia Yun could vaguely see that the dragon turned into a war knife was no longer a pure silver dragon, but with a trace of weird dark blue, and even, from time to time, there would be a few blood-colored spots of light flashing in the dark blue.

When Xia Yun had the ability to stand up, the coercion from the other party was no longer felt. It's just that because he consumed too much true yuan just now and vomited three mouthfuls of blood, Xia Yun still felt a little dizzy.

"Sister, Xia Yi-."

I really want to ask Xia Yi what happened just now and why she exclaimed, but she never got a reply from her sister.

What surprised Xia Yun was that the dragon turned from the war knife was not afraid of the ghost emperor he was facing. Not only that, but one ghost and one dragon are evenly matched.

It is equivalent to the fight between two human race gods who have cultivated into great power in the later stage, which suddenly makes the already dim and unknown Wandering Soul Origin even more eerie and terrifying.

The sound of the dragon's groan, the roar of the ghost emperor, and the collision of the dragon's claws and the meniscus in the opponent's hand sounded from time to time, shaking Xia Yun's eardrums, not to mention, the occasional leakage of the battle shock wave made Xia Yun stand unsteadily, so that he kept passively retreating, and it was not easy to work hard, and he was already more than ten miles away from the position where the two sides were fighting.

Boom, boom!

With two loud bangs, the battle in the distance came to an abrupt end.

A dragon and a ghost confronted each other for a long time, and suddenly, the dragon attacked again.

"Ahh

This time it was not Xia Yi's voice from the battle knife, but the exclamation of the ghost emperor who was equivalent to the late stage of the human race.

Xia Yun saw from afar that when the giant dragon attacked in front of the Ghost Emperor, it suddenly returned to its original form, and actually pierced the Ghost Emperor's body with a knife, penetrating through his chest, and rushing straight into the air from his back. After reaching a high altitude, he then turned around and dived, going straight to the top door of the Ghost Emperor and stabbed down.

Indeed, it was a thorn, not a chop.

Just when the Ghost Emperor wanted to dodge, the war knife suddenly stretched out a long dragon tail and wrapped it around the Ghost Emperor's chest, and at the moment when the Ghost Emperor couldn't move, the sword sneered at the top door of the Ghost Emperor and drilled in.

When the war knife was drilled out by the Ghost Emperor's gods, it was as if it had been nailed to the ground, and it stood there motionless like that, and there was no longer the slightest sound.

Seeing this, Xia Yun hurriedly flew over, but he didn't dare to reach out and grab the sword that was only less than a foot exposed.

Seeing that the Ghost Emperor tried to swing his body to get out of the battle knife, he couldn't do anything. Its ghost body is fading and becoming transparent at a speed visible to the naked eye.

Although the last time he was in the River Styx, Xia Yun didn't see how the war knife absorbed the energy of the ghost emperor quail clothes, but he saw the scene where he finally sucked the quail clothes into the battle knife. Apparently, the same scene is happening right in front of our eyes. In this regard, Xia Yun had some expectations in his heart.

However, Xia Yun is most concerned about Xia Yi's soul in the sword now.

It's just that no matter how Xia Yun contacts his sister, he can't get in touch.

Just when Xia Yun was at a loss, the battle knife had already completely absorbed the energy equivalent to the late stage of the human race god cultivator who had become a ghost emperor, and sucked him directly into the blade.

Seeing that the war knife was hovering in place for a while, it took the initiative to turn into a dragon body, carrying Xia Yun into the air, and galloping away in the Wandering Spirit Plain where Xia Yun couldn't distinguish between east and west, north and south.

Unexpectedly, this flight took a whole year. Although he couldn't tell the direction, Xia Yun could still feel that the dragon under him was always flying in one direction.

Today's dragon is not only no longer a silver dragon, nor is it no longer the color of the faint blue light on its body during the battle with the later Ghost Emperor, but has completely turned into an indigo dragon with a dark light in the blue.

How could such a change occur?

Xia Yun has not been in contact with his sister Xia Yi in the blade for a year, although he is very sure that his sister is still in it, and he can feel his sister's existence, but he still does not know his sister's current situation. This can't help but make Xia Yun's heart hold tightly for a year.

"Sister, Xia Yi, are you okay?"

Every day, Xia Yun didn't know how many times he would meet again, and finally, on this day, the war knife responded.

"Sister, I, I may have become the sword spirit of the war knife."

"No, absolutely not!"

Even if he gave up this war knife, which was very likely to be an immortal weapon, Xia Yun would never want his sister Xia Yi to become a tool spirit.

"Sister, actually, I've thought about it too, and it's good this way."

"No, absolutely not."

Although he was resolutely opposed, Xia Yun couldn't do anything. She couldn't command the sword to send Xia Yi's soul out.

"Sister, listen to me. First of all, there is no question of life and death when becoming an instrument spirit. What are we cultivating for, is it just to gain immortality and eternity? As long as this knife is not completely destroyed, I will always exist. Furthermore, there is no good way to escape the fate of becoming a machine spirit. Neither my sister nor I could do it. Therefore, it is better to accept this fate for the time being, and when my sister's cultivation is strong in the future, it is not too late to find a way. ”

After listening to his sister Xia Yi's words, Xia Yun was silent.

Yes, since there is nothing that can be done, what is the use of just disagreeing?

Although he has been a monk for some years, he has never come into contact with the magic weapon of the machine spirit. Not to mention, how to separate the machine spirit in the magic weapon. Xia Yun pondered for a long time, and finally could only secretly resolve that he must work hard to cultivate, and when he has the ability one day in the future, he will rescue his sister.
