Just when Dongyan felt unhappy with Ji Kaixue, Ji Kaixue, who had been on the defensive, was obviously getting more and more wrong.

"You forced me...... You forced me to ......"

Ji Kaixue's muttering became louder and louder, and looking at his eyes, it was completely as if he had lost his mind, rolling a pair of white eyes like dead fish eyes.

This kind of wrong appearance made Duan Fei's vigilance in his heart even higher, no matter how afraid Ji Kaixue was, he was the personal disciple of the master of the torture hall after all, so he wouldn't become the person he was now and completely irrational, right?

It was also at this time, in Duan Fei's mind, the black humanoid silhouette representing Ji Kaixue, among the various ability values marked by it, the spiritual power suddenly soared, directly breaking through the eight hundred mark, which means entering the Great Perfection Realm of Qi and Blood Realm!

Seeing Ji Kaixue's appearance, he had lost his mind, but why could his mental power still have such a big explosion? Could it be that the more abnormal his nerves, the higher this mental power would be?

Duan Fei defeated the strong several times, relying on the advantage of spiritual power to cast the voice of the Heavenly Demon and seek a chance to win, now don't capsize in the gutter and plant it in the hands of Ji Kaixue.

Of course, Duan Fei has Xiaomei's help, and the impact of mental power should not pose a threat to Duan Fei, but now it is not clear what kind of means Ji Kaixue is going to use.

At this time, many people watching the battle also saw that something was wrong with the situation, after all, Ji Kaixue's performance was very different from his previous behavior, what was so special about this?

And Ji Kaixue's next move finally solved the doubts in everyone's hearts.

I saw Ji Kaixue wave his hand, and suddenly a triangular black flag appeared in his hand, and it was the size of a zhang when it was displayed in the wind, and there was a ghost on the flag that looked like a god of death and was wearing a black cloak, lifelike as if it could come out of the flag, and the wind gusted with the appearance of the flag!

The onlookers didn't know how many people opened their mouths at the same time at this moment and exclaimed, "Soul Flag!!"

The so-called Soul Banner is the exclusive custom weapon of the Heavenly Demon Sect's Soul Peak, just like the body bag of the Bone Refining Peak, almost every disciple has one in their hands.

The exercises practiced by the Soul Loss Peak are related to the Yin Soul, this Soul Banner is a sharp weapon for storing the Yin Soul, once the Yin Soul is refined into a ghost ghost, then the power that erupts is by no means under those zombies and bone demons in the Bone Refining Peak.

In terms of personal combat effectiveness, the disciples of the Soul Loss Peak are not strong, but after they sacrifice the Soul Flag, their strength will have a earth-shaking change.

What's even more terrifying is that looking at the soul flag in Ji Kaixue's hand, it is actually the size of a zhang when it is unfolded in the wind, such a size is far beyond the ordinary soul flag, and only when the quality of the magic weapon is reached can such a large area be expanded.

And the magic weapon quality of the Soul Flag, is not just someone who is qualified to hold it, Ji Kaixue, as a disciple of the Blood Drinking Sect, how did he get such a Soul Flag?

Even if this Soul Loss Banner is the lowest quality among the low-grade magic weapons, but the Ghost Banner summoned from it can at least have the strength of the Great Perfection of the Qi and Blood Realm, how can it be so easy to deal with?

If there is any weakness of the Dead Soul Banner, it is that the person holding the Banner must have strong enough mental power, if the spiritual power is insufficient and forcibly summons the Banner Ghost, then for the summoner, it will damage the Divine Soul, and there is even the possibility of being controlled by the Banner Ghost in turn.

Ji Kaixue's mental power suddenly skyrocketed, obviously in order to exert the power of the Soul Flag, he used some kind of spiritual power secret method, and it is no wonder that his mental state has not been very normal, obviously his sanity has been affected.

It seems that for the sake of this life-and-death battle, Ji Kaixue has obviously let go, and he can't care about any consequences.

Moreover, Ji Kaixue's means were not only like this, at the same time as he sacrificed the soul flag, there was a loud roar in his mouth, and his voice was like piercing a golden cracked stone, with an indescribable sense of sharpness!

This kind of voice is not unfamiliar to Duan Fei at all, it is the sonic attack that contains the sound of the Heavenly Demon, as long as the mental power is lower than that of Ji Kaixue, it is easy to go insane under the impact of the sound wave.

As long as Duan Fei loses his mind a little under the impact of the voice of the Heavenly Demon, the Soul Banner will sweep up, and the Banner Ghost will absorb Duan Fei's soul into the Soul Banner while killing Duan Fei, making Duan Fei a controlled Yin Soul under the Soul Banner, and it may even be refined into a Banner in the future!

If this is the case, Duan Fei will not only be destroyed in form and spirit, but also immortal!

This Ji Kaixue can be regarded as a ruthless character, anyway, he has to work hard, so he will definitely make Duan Fei unhappy regardless of the cost!

Ji Kaixue has used these methods one after another, it seems that he wants to fight a turnaround battle, and now what makes everyone suspicious is that it is not only the origin of the Soul Flag, but also the magic power of this Heavenly Demon Voice, where did Ji Kaixue learn from?

Now Dongyan's face is even more ugly, Ji Kaixue can have the means to fight back, he should have been happy, but the magic weapons and exercises used by Ji Kaixue have nothing to do with him as a teacher.

In this way, even if Ji Kaixue can win in the end, Ling Dongyan will lose face and have to find a personal disciple again.

As for Ji Kaixue, when facing a life-and-death battle, he was still so worried, as long as he could defeat Duan Fei and save his life, he was willing to do anything!

Especially now, when Ji Kaixue exceeded his limit and sacrificed the soul banner of the magic weapon quality, it can be said that he endured the pain of his soul like a burning flame every moment, if he didn't solve Duan Fei sooner, Ji Kaixue would even wonder if his soul would be completely incinerated.

After the voice of the Heavenly Demon came out with a loud roar, Ji Kaixue, who was not very conscious, didn't care about whether it had an effect on Duan Fei at all, but directly drove the divine thoughts with all his strength and summoned the black phantom on the Soul Flag.

This black phantom is the ghost stationed in the Soul Flag, which is equivalent to the role of the machine spirit, Ji Kaixue reluctantly summoned it after burning his own soul, limited by Ji Kaixue's realm, the ghost at this time is far from reaching its heyday, and can only exert the combat power of the Great Perfection of Qi and Blood Realm.

But even if that's the case, it should be enough to deal with Duan Fei, right?

As the banner ghost flew out of the mourning flag, its soul body turned from virtual to solid, and with a few terrifying screams, it rushed towards Duan Fei!
