Ao Xuan casually found a barren mountain to stop, asked Daji to help him protect the Dharma, and after arranging a magic circle, he went to find Nuwa Niangniang.

"Something isn't right!"

Seeing Nuwa Niangniang, Ao Xuan immediately expressed his suspicions.

Nuwa Niangniang's gaze fell on the Zhuxian Sword in Ao Xuan's hand.

"It's so easy!" she said.

Ao Xuan nodded: "Even if Guang Chengzi didn't expect it to be me in Tianshui Palace at the beginning, after seeing me, he should be vigilant." ”

"Why do you still take out the Zhuxian Sword when you know that you are not my opponent and you are still sure to escape?"

"Those eighteen Great Luo Golden Immortals seem to be desperate, but they have not exerted the strength of the real Great Luo Golden Immortals at all. ”

"As for Guang Chengzi, he is like that, where does he have the appearance of the first person of the Twelve Golden Immortals of Jade Void under the throne of Yuan Shi Tianzun?"

"And this Zhuxian Sword, I always feel a little weird!"

Ao Xuan said all his doubts in one breath.

Nuwa Niangniang noticed that the Zhuxian Sword in Ao Xuan's hand was sealed.

Ao Xuan used the "Taishan Star" among the twenty-four stars to seal the Zhuxian Sword and prevent it from leaking out the slightest breath.

"You seal it, but you have to open it. If we don't open it, we won't know the answer. Nuwa Niangniang said, waving her hand to set up a formation.

Nine days of rest, the two magic weapons of the infinite umbrella of the main defense are protected by the left and right.

And then with the Heavenly Refining Furnace and the Creation Immortal Ding as the eyes, no matter what comes out of the Immortal Sword for a while, it can be blocked.

Ao Xuan also offered glazed golden bells and Baolian lanterns as supplements.

After preparing for the ten thousand swords, Ao Xuan took back the sealing power of the "Taishan Star".

The Zhuxian Sword was quietly suspended in front of Ao Xuan and Nuwa Niangniang.

It's like nothing happened.

It's as if nothing is going to happen.

Ao Xuan narrowed his eyes and cast an inquiring glance at Nuwa Niangniang.

Nuwa Niangniang thought for a moment, then pricked her finger with her fingernails and squeezed out a drop of blood.

Almost at the same time as Nuwa Niangniang's blood appeared, a disturbing aura immediately poured out from the Zhuxian Sword.

The dark red blade began to turn black, but in the blink of an eye, it had become pitch black.

An aura of madness, disorder, and destruction poured out of the sword.

Ao Xuan and Nuwa Niangniang snorted coldly at the same time.

As soon as the glazed golden bell rang, the unclean aura was immediately dispersed.

The Baolian Lantern immediately lit up the Seven Treasures Wonderful Fire, and completely wrapped the Zhuxian Sword along the veins of the formation.

As for the unclean aura that spread out after being shaken away, it was blocked by the Nine Heavens Breath and the Infinity Umbrella.

Not only could he not run out of the formation at all, but it was impossible to get on Ao Xuan and Nuwa Niangniang in any way.

Both of them have already discovered that this unclean aura is the thing that induced Nuwa Niangniang's demons before.

Just when this thought appeared, the Zhuxian Sword shook violently.

Then everything calmed down.

It's just that the Zhuxian Sword has changed from its original dark red appearance to pure black.

It was as dark as if there was nothing there.

Looking at it from Ao Xuan's point of view, he couldn't even see the sword body, but only saw a sword-shaped black barrier.

He frowned, "What is this?"

Nuwa Niangniang said, "War book, but we need ......," she said, holding out her hand.

"Wait!" Ao Xuan stopped Nuwa Niangniang, "I'll come!"

Nuwa Niangniang glanced at him, didn't argue, and took a step back.

Previously, Zhu Xianjian reacted to Nuwa Niangniang's blood, maybe there was something specifically designed for Nuwa Niangniang.

At this time, Nuwa Niangniang is quite weak, and if she falls for any conspiracy, it will be a big trouble.

Ao Xuan took a deep breath, and after adjusting his state, he stepped forward and held the Zhuxian Sword.

The blade of the sword was light, as if it had no weight.

But there's nothing strange about it.

Ao Xuan was about to say this, but suddenly found that the Zhuxian Sword lit up.

It's not that the blade of the sword changes from black to another color, but that there are bright spots like stars on the top of the sword.

That scene was like looking up in the middle of the night, the dark clouds in the sky dispersed, and the sky saw the stars at first glance.

At the same time, a voice sounded in his head.

Ao Xuan's heart tightened, and he immediately prepared to defend.

However, when he focused his attention, he realized that the voice was not a sound.

It's more like an idea.

The content of the idea is also very simple.

Just one word.

Kill!

But that's all.

Ao Xuan only needed to divert his attention, and the voice was gone.

Ao Xuan immediately began to examine himself, and it was certain that there was no effect on him.

It's very simple to "hear" that voice, but if you concentrate your attention on it, you have the idea of "listening" in your heart, and the idea of that voice will come.

It comes straight to the back of my mind, like a piece of information that is imprinted directly into my mind.

Or rather, it was more like a thought rising in Ao Xuan's own heart.

But that's all.

Ao Xuan, who is already a quasi-saint, is still quite confident in his self-control, plus he has an infinite dragon domain and twenty-four stars.

It's kind of funny that he can't be sure if anything has an effect on him.

But it was precisely because he was sure that the Zhuxian Sword had no effect on him that he became even more confused.

So what is this sword's "broken thoughts" trying to do?

Ao Xuan shook his head, and then told Nuwa Niangniang the situation in detail.

Nuwa Niangniang thought for a while and said, "That kind of whispering is normal, I have heard Tongtian say that it is indeed terrible for mortals or people with low realms. ”

"But from the beginning of Da Luo Jinxian, that whisper no longer has any threat. ”

"After all, this thing was once owned by the Demon Ancestor Rahu, and it is normal to have some strange things. ”

Ao Xuan thinks it makes sense.

It seems that whispering is not useless, but it is ineffective against immortals whose strength has reached the level of Da Luo Jin Immortal or above.

After all, no matter how powerful the magic weapon is, it must be used.

He let go of the Immortal Sword and let it continue to levitate in the formation.

The "starlight" on the sword's body immediately disappeared, and it turned into pure darkness again.

Gripping the hilt of the sword again, the starlight reappeared.

"In other words, what is really problematic is this pitch black and starlight, not a whisper?" Ao Xuan asked.

Nuwa Niangniang nodded: "At least I have never heard of the four swords of Zhuxian having such strange characteristics. ”

"And, have you found out?"

Ao Xuan narrowed his eyes, and the Dominating Star rose.

He saw a large number of causal swords wrapped around the Zhuxian Sword, and these causal threads spread outward, forming a huge web.

"There are so many causes and effects on this sword. ”

Nuwa Niangniang nodded, "So the purpose of the person behind the curtain is very clear, this sword is a war book and an invitation." ”

Ao Xuan shrugged: "It's really generous, the Zhuxian Sword will be sent with a click." ”

Nuwa Niangniang smiled: "You dare to use it?"

Ao Xuan also smiled: "Why don't you dare?"
