As a life-sustaining lamp went out, a black gas emanated from the old man's body.

"Boom!"

There was another boom, just as suddenly as the shaking just now.

Mi Fangzun looked shocked, and then said, "Senior, what's going on?"

Mi Fang Zun is not a fool, after being the leader of the Sect Leader Alliance for so many years, he needs to look at the Sect Leader Alliance as a whole, and it is naturally impossible not to see the changes in this old man.

Ling Fei's eyes narrowed slightly, in his opinion, these life-sustaining lamps did not seem to be used to renew the life of the old man, but to suppress the old man's cultivation.

"Alas!" the old man sighed, and with a wave of his palm, a crystal stone shot out of his hand and headed straight for the Secret Boat.

Mi Fangzun instinctively caught the stone, and then looked at the old man with a strange face: "Senior......"

"Needless to say, you guys should get out of here!"

The old man waved his hand and motioned for Ling Fei and Mi Fangzun to leave.

"I'm afraid, we can't leave!" Ling Fei said with a sigh.

The old man only looked at Ling Fei at this time, although Ling Fei was a demon beast, but he didn't care at all: "What do you mean by this?"

The old man had a strange expression, as if he had guessed something.

"The senior should have guessed something!" Ling Fei also seemed to see something from the old man's face, and said strangely.

"I expected that the demons would actually let you enter here, naturally hoping to make the old man succumb......" The old man was silent and shook his head slightly.

"I'm afraid that the senior's Shui Rue Jade is used to suppress the black qi around his body!" Ling Fei could see that after the old man took out the Shui Rue Jade, the black qi on his body also began to thicken.

"Sort of!" The old man didn't seem to expect Ling Fei to be able to see it so quickly, and he was a little helpless.

Mi Fang Zun was a little incomprehensible at first, but immediately his eyes flashed, and he said, "Senior, you were invaded by demonic qi?

I don't know how strong this old man's strength is, but now he can only use the life-sustaining lamp and water ruel jade to survive.

"It seems that none of the people who can get here will be easy!" the old man did not deny it when he heard this, and then said: "Then don't leave quickly, if you don't leave, you may fall here!"

"Tianfang, they can't do without it, they can only enter here by opening the Demon Formation, since they are here now, it means that the formation has been opened, you should also feel the changes around you!" At this moment, a voice came from him, this voice was sinister and sarcastic.

"Seventh Ancestor, the old man's life-sustaining lamp is still extinguished!" The old man stepped on his feet, and the black qi on his body was dark.

Looking at the changes in the old man's body, Ling Fei and Mi Fang Zun both looked at the old man a little strangely.

"Don't go quickly, I can't suppress this demon for long!" the old man snorted.

"Senior, if this water ruel is on you, you should be able to resist the invasion of this demon, I ......" Mi Fang Zun frowned and looked at the water ruel in his hand.

Obviously, the old man is being taken away at this time, if he can, Mi Fang Zun would rather not take this water rue jade, and also hope that the old man can live.

In this place of the Immortals, there are not many powerful martial artists, and it is even rarer like the old man, if it is invaded by the demons, it must be a huge help.

"It's useless, after so many years, the old man's cultivation has been consumed too much, and he can't resist this demon anymore, you can only leave quickly, otherwise you ......" The old man sighed.

"Let's go!" Ling Fei also spoke, in his eyes of destruction, the old man's body was surrounded by Dao aura, these black qi were gradually burrowing into the old man's body, as the old man's aura disappeared, the black qi had gradually gained the upper hand, I am afraid that in just a moment, the old man will be completely taken away.

As Ling Fei's words fell, another life-sustaining lamp went out.

"......" Mi Fang Zun was about to say something, but the old man directly said loudly: "Go!"

Mi Fang Zun nodded, and could only leave with Ling Fei in the way he came.

Originally, when Mi Fangzun came, he was still very afraid, but now it seems that it is no longer fear, but heavy, the changes here are much heavier than he imagined, the strong man of the human race is about to fall in front of him, but he has no way, the only thing he can do is to flee for his life.

Although Ling Fei is not a human, in his heart, he is still a human, and he is also in a heavy mood, watching a strong man about to fall in front of him.

But what was even more terrifying was that when they walked out of the main hall, there were countless black mountain stones around them, and countless black trees appeared in the distance, and it seemed that even the fifth and fourth layers were also fused here.

"What exactly is the formation we opened?" Seeing all these changes, Mi Fang Zun couldn't help muttering, obviously it was the formation they opened, which is why the formation has changed so much.

"It should be the formation that changes the structure of this Demon Domain, but I'm afraid that if we don't leave immediately, we will stay here forever!"

Ling Fei could feel an incomparably powerful demonic aura coming from the hall behind him.

......

In front of the underground stone hall.

The life-sustaining lamps floating in the void went out three times again, and the expression on the old man's face began to change violently.

It was as if a layer of black mist began to cover his face, and this black mist also made the aura on the old man's body gradually wither.

"Tianfang, why struggle, embrace me, you will gain true eternal life, and you will also become a powerful existence that everyone looks up to, not obscurity!"

A voice came from the old man's body again, only this time, it was obvious that the owner of this voice seemed to be much stronger, and was no longer easily suppressed by the old man.

"Seventh Ancestor, my life-sustaining lamp hasn't been completely extinguished yet!" he glanced at the floating life-sustaining lamp, and then said with a dry cough.

"If you hadn't handed over Shui Yunyu, you might have been able to suppress me for decades, but now, these life-sustaining lamps can only be extended for a few moments for you, and I've been waiting for a long time in this endless wait!"

The cold voice spoke slowly.

"Yes, even if you get my body and can descend to this realm, there will still be people who can stop you, don't you feel the breath of the people in the upper realm?"

The old man closed his eyes, as if he was resisting the invasion of demonic energy with all his might, and he began to have some difficulty speaking.

"People from the Upper Realm, hehe!" the voice sneered, and then said: "The Upper Realm is just a little stronger than this interface, it is the same for my Seven Ancestors, and when it comes to this realm, it would be good for this person to be able to exert thirty percent of his strength, and it would be hindered, so I would be different!"

As he spoke, the life-sustaining lamp went out ten more times......
