Ning Xianyu's headache felt like it was about to explode and she couldn't concentrate at all.

She tried to transform Xuanyuan Tunhan back, but was interrupted by pain every time she tried.

【System, help me. 】

The system quickly said: [Give me these painful feelings, I will help you take them away, and then give you a pack of painkillers in return. ]

Ning Xianyu quickly said, "Okay," "Hurry up and give me the medicine."

The system gave her a pill while drawing out her emotions.

Ning Xianyu suddenly felt something extra in her throat. She quickly swallowed it, and the pain was indeed much less.

She tried to change quickly, but with a bang, the little black cat turned back into a big devil.

The man in white robe was stunned for a moment in surprise, and then he was hit hard in the face.

He took two steps back and stopped casting the spell.

Ning Xianyu felt no pain instantly, and when she saw the big devil standing in front of her, she breathed a sigh of relief.

Xuanyuan Tunhan suddenly turned around and slashed Ning Xianyu with a sword, scaring her into screaming.

But after she screamed, she realized that the vines that were wrapped around her were cut off.

She landed on the ground and carefully hid behind him.

Xuanyuan Tunhan pointed his sword at the man in white robe and said, "You are very brave, Nian Laisheng."

Ning Xianyu poked her head out and asked in confusion, "Is this Nian Laisheng, Xunian's master?"

Is he the person who was brought here temporarily as mentioned in the legend?

Have they been plotted against since they entered Shifang Mountain?

Nian Laisheng smiled and said, "Senior Xuanyuan, I have always been timid. I have considered this for a long time before making the decision. Please forgive me."

[What a nice thing to say. You didn’t show any cowardice when you attacked me just now.] Ning Xianyu cursed Nian Laisheng in her heart. If she could, she would have wanted to go up and hit him a few times.

Xuanyuan Tunhan said angrily: "You want to keep me here and let me offer sacrifices to the heavens ten thousand years later?"

Even though his bad behavior was exposed, Nian Laisheng still smiled calmly, and even said it was a matter of course: "That's right."

Xuanyuan Tunhan frowned: "Have you reached the Void Realm?"

Nian Laisheng still smiled: "Luckily, I passed the Void Realm in the past two years."

Xuanyuan Tunhan laughed sarcastically and said, "You are still hiding your true intentions even after reaching the Void Realm. Thinking about your next life, you are still as timid as ever. I never thought you would be so calculating."

He tied the sword to his hand and said angrily, "Now that you have reached the Void Realm, you know what will happen. It's your turn."

But Nian Laisheng said, "No, it's your turn, senior. It is indeed your turn based on seniority. I want to trap you here for the safety of the six realms of Yunhuang."

"You know very well that if you want to be a sacrifice you must be purified in the outer space for 10,000 years, otherwise you won't be able to suppress the evil spirit of the Demon Star at all."

Ning Xianyu instantly thought of the person in the Lingshu Secret Realm, who was Xuanyuan Tunhan’s great master.

It seemed that that person had stayed in the Lingshu Secret Realm for ten thousand years, and after coming out, he was put into a bottle and used for sacrifice to the sky.

According to what Nian Laisheng said, it seems that there will be a sacrifice every ten thousand years, and the sacrifice must be prepared ten thousand years in advance, just to suppress the evil star in the demon world?

So many powerful people with profound cultivation have been waiting alone in the secret realm for ten thousand years, but are they waiting to die?

【What's going on with this extremely sad atmosphere? 】

Ning Xianyu couldn't help but step forward and grab Xuanyuan Tunhan's sleeve. Could it be that the big devil would be the next one?

Xuanyuan Tunhan sensed her nervousness and depression, and involuntarily turned his head to look at her, but did not shake off her hand.

However, he turned his head to look at Nian Laisheng and said sarcastically, "You are just afraid of death. To be a sacrifice, you must pass the Shattered Sky Realm. Now you have far passed the Shattered Sky Realm and reached the Void Realm. It is most appropriate for you to be a sacrifice."

Nian Laisheng shook his head: "I am not afraid of death, but my realm is unstable. This cultivation is all temporary. It is just a fortress built on sand. It will fall apart at the slightest touch. I will have to wait another 20,000 years before I can be the sacrifice."

He bowed and said to Ning Xianyu: "Daoyou, for the safety of the six realms of Yunhuang, please stay here with Senior Xuanyuan for ten thousand years to purify the world. With your company, I think Senior will not be too lonely."

Ning Xianyu didn't expect that she had her own business to deal with here.

"But what are you talking about? Why can the sacrifice suppress the demon star?"

Up to now, she was still completely confused and had no idea what was going on.

Nian Xiasheng probably wanted to keep her, so he kindly explained it.

"When the Demon Star descended upon the world, the Demon Realm became a purgatory. The cultivators from the six realms united to fight against the Demon Star and tried to restore the Demon Realm, but all their efforts were in vain."

"Until one day, a cultivator accidentally entered the life circle of the Demon Star and sacrificed himself to suppress the demonic energy of the Demon Star. Then everyone figured out a way to temporarily suppress the Demon Star."

Ning Xianyu nodded: "So the method is to send a pure cultivator to him to eat every ten thousand years?"

Isn't this equivalent to washing a highly skilled monk and giving him away to others to eat?

It’s both tragic and terrifying just thinking about it.

Just think about it, waiting for ten thousand years, working hard to purify yourself, just to be eaten by others.

Isn’t this horrible?

Xuanyuan Tunhan glanced at her but said nothing.

Nian Laisheng smiled bitterly and said, "That's true, but if not, the evil star will continue to expand and destroy the entire world. By then, more than one or two people will die."

This is really, sacrificing the small self to save the big self.

It seems that those monks who were previously mentioned as going to deal with the Demon Star and ended up disappearing have all gone to find a place to purify themselves.

And Xuanyuan Tunhan is probably the executor, responsible for sending the purified monks to the Demon Star.

Those he sent away were all his friends, fellow Taoists and even fellow disciples.

When I think about it this way, doing this every ten thousand years, bidding farewell to old friends one after another, this is too terrifying.

Ning Xianyu's grip tightened: "You two are the only two people in the world who can be sacrifices?"

There is a serious gap in the number of cultivators with high cultivation levels. It is said that there are not many who have passed the Deification Realm, let alone those who have reached the Shattered Sky Realm and the Void Realm.

Nian Laisheng said, "Now we are the only two who have passed the Shattered Sky Realm."

Ning Xianyu asked again: "How do you know which sacrifice is effective?"

Is this a great secret?

How come I've never heard anyone mention such a big thing?

Nian Laisheng said: "Because this is a secret that only cultivators who have passed the Shattered Sky Realm can know."

"Back then, Senior Xuanyuan placed a ban on the six realms of Yunhuang. As long as you pass the Shattered Sky Realm, you will automatically receive the truth about maintaining the stability of the Demon Star and the six realms."

“But in these years, since all the predecessors have gone to offer sacrifices to the heavens, no one has passed the Shattered Sky Realm, so no other cultivators know about this matter until now.”

Now that there are only the two of them, he thinks he is not suitable. Seeing that Xuanyuan Tunhan has no intention of purifying himself, he forces Xuanyuan Tunhan to purify himself.

But Ning Xianyu felt that sacrifice had to be voluntary and could not be forced.

If the big devil didn't want to go, she could totally understand.

But at this time, the big devil said: "The suppression of the demon star has reached its limit. I just sent the last sacrifice a few days ago. After that, sacrifices will no longer be useful. You are just wasting your time."

Nian Laisheng was horrified: "Senior, are you saying that the six realms of Yunhuang only have 10,000 years left?"
