Uncle Zhu in black briefly introduced the purple stele in front of him, and after listening to Uncle Zhu's explanation, Xiao Yao and the others quickly raised their heads and looked behind the stele inside.

Behind the stele is a purple mountain.

This mountain is very tall and very large, at first glance, it is afraid that it is thousands of meters high, and it is indeed surprising that such a majestic purple mountain appears here.

Feeling this mountain, Xiao Yao's eyes closed slightly, and a divine sense swept towards these mountains, he wanted to see what this purple mountain was.

With this sweep, Xiao Yao couldn't help but be slightly taken aback.

Because this mountain is really like what Uncle Zhu said, these purple spars are all extremely rich magic stones, and these magic stones contain extremely rich magic energy, and this rich magic energy is definitely several times higher than the high-grade magic stones in the demon world.

If no one comes to pick such a strong demonic qi, it means that this place is really dangerous.

Immediately, Xiao Yao opened his eyes, and his face turned cold.

"Okay, since you have reached your destination now, then you wait for me outside, I'll go in and have a look alone, remember to hide your bodies..."Xiao Yao glanced at Huofeng, Hu Batong and the others and said softly.

Hearing that Xiao Yao wanted to go in alone, Huo Feng and Hu Baguan hurriedly stepped forward anxiously.

"Your Excellency, let us follow you in, in case you run into danger inside, it'll be over... We don't know what happened to you then..."

"Yes, Mr. Xiao, you just let us go in with you, my master and I are very powerful, if I really encounter any danger, I can escape by releasing a ghost qi, don't go in alone..."

Huo Feng and Hu Baguan both pleaded with Xiao Yao.

They really didn't want Xiao Yao to go in alone, because it was really too dangerous inside, and if something happened to Xiao Yao inside, then they really didn't know what to do.

At this time, Xiao Yao, who was standing in front of the stone stele, looked at the pleading appearance of Huofeng and Hu Baguan, and his brows furrowed.

Then he shook his head and didn't agree.

"No, it's too dangerous inside, if you go in and encounter danger, you will definitely die, now you are waiting outside, if I really encounter danger inside, I will definitely send you a signal, when the time comes, you just need to notify the Yaochi Immortal Emperor and the Yunlan Immortal Emperor..."

Seeing that Xiao Yao still didn't agree to let him in, Huo Feng and Hu Baguan also suddenly frowned and wilted.

They knew that as long as Xiao Yao didn't agree, it would definitely be impossible for them to go in, so they could only bow their heads and agree.

Seeing that Huo Feng and Hu Baguan no longer spoke, Xiao Yao also breathed a sigh of relief.

He was afraid that they would follow, and it was good that they had come down now.

"Okay, then you hide here, and if there is danger inside, I will notify you..."Xiao Yao said softly.

After saying that, he turned around and walked directly behind the stone tablet.

……

There was a very shallow white line around this stone stele, and when Xiao Yao's feet stepped into the white line, a cold air immediately poured out from inside.

The cold air was more than a dozen degrees cooler than the air outside, as if it was winter inside and summer outside.

Feeling this two-level temperature difference, Xiao Yao frowned and didn't say anything, he still walked slowly inside.

Behind the stele is indeed a tall mountain, and Xiao Yao came to the bottom of the stone wall of this mountain as if he had come to a paradise.

Coupled with the cold air that bubbles up from time to time around him, he feels that this place is very mysterious.

In this way, Xiao Yao walked inside for more than ten minutes, and when he walked around the mountain to the back of it, he found that there was a stone staircase that went up here.

The steps on the stone staircase are so clean that it looks like someone is cleaning them here.

Looking at this staircase that suddenly appeared, Xiao Yao hurriedly walked over, he had to quickly find the location of Liu Wenfei and his mother.

In this way, Xiao Yao has been walking along the stone ladder for a distance of hundreds of meters, and when he reached the end of the stone ladder, he was stunned again.

Because the end of this stone staircase turned into a step that went down, and from here, there was really a valley at your feet.

This valley is extremely beautiful, and it is full of large trees two or three meters high, which are different from ordinary trees, because their trunks and leaves are also purple, and there is some magic on these purple leaves.

In addition to these large purple trees, there is also a small stream in the valley that flows slowly, and the water of this small stream is normal, not as strange as those large purple trees.

But the purple trees and the stream were on the edge of the valley on all sides, and in the middle of the valley was a huge clearing.

There is a circular altar in the middle of the clearing.

This circular altar is very huge, it looks like it is thousands of square meters from here, and there is a huge purple stove in the middle of the altar, and there are several people tied around the stove.

Looking at the stove in the middle of this altar, and then at the few people around the stove, Xiao Yao exploded in an instant.

Because he saw that the people around this stove seemed to be Liu Wenfei and his mother.

Immediately, Xiao Yao hurriedly walked down the valley without saying a word.

He had to hurry up and rush to the middle of the altar to save Liu Wenfei and her mother.

However, when Xiao Yao walked down the stone stairs and walked to the bottom of the valley, he saw that the huge altar in front of him suddenly disappeared.

Not only did the altar disappear, but so did the stove in the middle of the altar and the people around it.

Now in the middle of this valley is a clearing.

The clearing was painted with some strange patterns, which were black and looked very quaint.

Looking at this huge open space that suddenly appeared, Xiao Yao was suddenly stunned.

He stood on it just now and saw it clearly, there was definitely an altar here, and Liu Wenfei and her mother were standing on the altar, but now there was nothing!

Now Xiao Yao's brows were furrowed, and the look on his face was full of vigilance, he knew that this place was definitely very dangerous.

But even if it's dangerous, he's going to break through.

Immediately, Xiao Yao slowly raised his feet and walked towards the middle of this valley, and after a while, he walked to the circle in the middle position.

After walking to the circle, he also saw the quaint lines under his feet clearly, which seemed to be connected together by a formation, which made people dizzy to watch.

Looking at these dense formations, Xiao Yao frowned and didn't dare to move forward, he was afraid that these formations would be dangerous.

You must know that although Xiao Yao is the first immortal emperor in the hall, his research on the formation method is the worst, because when he was in the immortal realm, he had not studied these things at all, so how could he not take these things seriously now.

Soon, he stared at the lines vigilantly, and after reading them, he didn't find any danger.

Maybe I just thought too much, and there might not be any danger here.

Thinking of this, Xiao Yao slowly raised his steps and continued to walk forward, but when he took a step forward, his big foot had just landed, only to see a huge black iron cage suddenly gushing out around him.

The black iron cage enveloped him in an instant.

Seeing that he was suddenly wrapped in an iron cage, Xiao Yao was also angry now, he didn't expect to be fooled, there was really a trap here.

However, before Xiao Yao could speak, he heard a burst of wild laughter ringing in the valley.

"Hahaha... Emperor Qingyuan, I didn't expect this small formation to trap you inside, this really surprised me a little! Aren't you the first immortal emperor in the dignified immortal realm, why can't you even solve the small formation now? hahaha..."

This burst of wild laughter was even arrogant, as if he was mercilessly mocking Xiao Yao.

Hearing this burst of merciless laughter, Xiao Yao's face became more and more gloomy, and he knew who this wild laughing voice was.

It's no one else.

He's the Demon Lord Nightfall he's looking for!

Xiao Yao didn't expect that Nightfall would already know that he had come here.

Listening to the wild laughter echoing in the valley, Xiao Yao slowly raised his head and looked up, with a hint of murder in his eyes.

"Hmph, Nightfall, since you know that I am the First Immortal Emperor of the Immortal Realm, do you think these broken things can trap me? Don't be too happy, these things are rubbish to me!" Xiao Yao said in a deep voice.

After speaking, a golden light flashed in his hand, and then he swung directly towards this iron cage.

"Boom!!"

There was a muffled sound, and I saw that this iron cage was instantly smashed by Xiao Yao's palm, and after the black iron cage disappeared, the lines under his feet appeared again.

Watching Xiao Yao smash the black iron cage, the wild laughter around him slowly turned into a cold snort, but the tone was not particularly angry, but seemed to be very disdainful of Xiao Yao.

"Hmph, it's worthy of being the First Great Emperor Qingyuan!, but if you want to break through my Ten Thousand Demon Array, then I'm afraid you'll have to pay some more strength..."

"Besides, let me tell you, you only have ten minutes, and if you can't break through this Ten Thousand Demons Array in ten minutes, then your woman and your mother will be thrown into this furnace... Hahaha... I hope you take advantage of the opportunity..."

This burst of laughter came from the valley again, and the voice grew more and more arrogant.

Before the roar of laughter had subsided, a huge circular altar appeared in the middle of the valley.

This circular altar was more than ten meters high, and Xiao Yao was now standing at the edge of this altar.

He looked up at the circular altar, and he suddenly noticed that the stove on it and Liu Wenfei and her mother had reappeared on it.

And now it is obvious that Liu Wenfei and her mother's bodies are getting closer and closer to the huge furnace, as if it will not be a while before they will be thrown into this furnace.

Seeing that Liu Wenfei and her mother appeared on the altar again, Xiao Yao raised his head excitedly and roared loudly, but his roar was useless, as if he couldn't be heard on the altar at all.
