The middle-aged monk surnamed Wang in front of him should be a cultivator in the Jindan period, and his flying speed is not fast, and Lu Xuan can follow it with ease.

He observed his surroundings and pondered silently.

Obviously, the name Grey Slave is a generic term.

The senior of the Heavenly Machine Gate should have discovered the talent of the Gray Slave Clan, and knew that they were good at finding immortal stone veins, so he set up a formation in their minds. The gray slave Lu Xuan met was just one of the many gray slaves.

Lu Xuan could understand why that Tianji Sect senior was so painstaking.

Although this secret realm looks vibrant, the aura in it is not much stronger than that of the outside world. It is isolated from the world, and the aura cannot be replenished, but can only be gradually depleted.

However, there should be many young prison cultivators in this secret realm, and if they need to practice, they can only rely on immortal stones.

The Grey Slaves would come back once every ten years, and the monks in this secret realm would know where there were immortal stone veins, and then venture out to mine immortal stones and come back.

It seems that the situation of the predecessor of the Tianji Gate is also quite embarrassing.

Lu Xuan followed the middle-aged monk all the way, and also saw the scene in this secret realm.

Here, there are countless human beings.

There are simple and simple stone houses everywhere in the mountains, and I don't know how many men, women and children live here. And in the mountains in the distance, you can often see an amazing aura rising into the sky. It was at least the aura emitted by a human monk at the level of the Human Emperor, and Lu Xuan followed the middle-aged monk for only a few hundred miles, and he saw three similar rays of brilliance.

In this secret realm, are there so many mortals and human emperors living side by side?

In an instant, Lu Xuan suddenly realized.

He realized that this secret realm was probably the only refuge in the world of the young prison.

The secret realm is a shattered void, which should be able to block the invasion of ghosts, and the young prison humans and monks will not encounter danger when hiding in this secret realm.

This is probably the last safe area in the world of the Young Prisons.

Lu Xuan followed the middle-aged monk for more than two hours, and in the extreme distance ahead, a majestic mountain peak flashed.

Lu Xuan suddenly paused, looked at the mountain peak and frowned.

At this moment, in the void on the side of the mountain peak, there were five powerful figures, blooming with dazzling brilliance.

It was obviously the powerhouses of the five Human Emperor realms, staring at that mountain peak with fierce eyes.

Something seemed wrong with the atmosphere.

Lu Xuan saw that the middle-aged monk in front of him was still ignorant and rushed straight over, so he suddenly appeared behind him, and a runic light passed, stunned him, and then put the gray slave into the furnace.

Although he didn't know what the five human emperors were doing, it was clear that the situation was not good.

After settling the middle-aged monk, Lu Xuan stuck to the ground and cautiously flew towards the peak.

......

When he was a little closer to the peak, Lu Xuan saw the five human emperors clearly.

It was four men and one woman, all of them were old men, and the surroundings were dazzling, especially the red-haired old man in the center was the most powerful, and the surging true yuan was like a raging fire, and even the sky was steaming and trembling.

"Xia Daoyou, I've been waiting here for a long time, haven't you even seen it?"

The red-haired old man's voice was like a bell, shaking the grass and trees on the mountain in front of him.

Finally, from the top of the mountain, a tall and thin figure stood up. Lu Xuan hurriedly gathered his eyes and looked over, and saw that the man's face was narrow and long, his face was pale gold, and he was also an old man.

"Flame Monarch, Xia Daoyou has been in retreat for a hundred years, and he has never seen outsiders, you have long known this matter, so why be aggressive?"

The man said lightly, his voice was tingling with a chill, even if Lu Xuan was dozens of miles away, he still felt a gust of cold wind.

The Flame Monarch looked at the man fiercely and sneered: "Huang Ting, it is precisely because Xia Daoyou has entrusted this Cave Heaven World to you to manage, and you can see what the Cave Heaven World has become in the past hundred years? Now that the spiritual energy in this heaven and earth is lacking to the extreme, and the immortal stones are almost exhausted, how can we, the Daoists, practice? ”

Huang Ting said: "If the Flame Monarch wants to hold me accountable, after Xia Daoyou is out of the customs, he will naturally give you an answer." As for the immortal stones you mentioned, after two years, Xia Daoyou's gray slaves will return one after another, and I will naturally send people out to collect immortal stones at that time. ”

"Don't be ashamed!"

The Flame Monarch said sharply: "Eight years ago, the Grey Slave came back once, so what? you have exhausted a year, and the immortal stones you brought back are insignificant, and they will be consumed in just one year. Now that there are fewer and fewer immortal stones in the Shaojiao world, even if you get the news of the immortal stone vein two years later, how much can you get back?"

A pale golden light flashed in Huang Ting's eyes, and he said coldly, "Then what do you want?"

The Flame Lord suddenly smiled.

"Huang Ting, you don't have to hide it, we know that the gray slave comes back every ten years, and a large part of the immortal stones you go out to collect will be deducted. This cave heaven mountain has a majestic aura all day long, which is proof of this! Although this cave world is supported by Xia Daoyou's mana, there is no need for so many immortal stones, right? We have a few Taoist friends visiting today just to ask Xia Daoyou to give up some immortal stones for us to practice. ”

Huang Ting was suddenly furious.

"Flame King, you fart!"

He pointed at the Flame Monarch and the others, and said fiercely: "Why Xia Daoyou is in retreat, don't you know? For more than two hundred years, Xia Daoyou has exhausted his efforts to maintain this Cave Heaven World, if there is no immortal stone to support it, do you think this Cave Heaven World can still last? You are protected by Xia Daoyou, you don't even know how to be grateful to Dade, and you still covet Xia Daoyou's immortal stone, it's really shameless!"

"Shame?

The Flame Monarch suddenly said sharply, "What good do we have in this Cave Heaven World? This Heaven and Earth is so big, like a cage. You have never refused to open the cave world and let us out, who knows what the outside is like now? Maybe the ghosts have long since disappeared, or maybe the outside has returned to the pomp and circumstance of three hundred years ago, and we can only stay in this square inch of the place, how sad is it?"

He pointed at Huang Ting with his halberd, and said fiercely: "Today, you either hand over the immortal stone, or open the cave world and let us out, otherwise the five of us will never give up!"

"That's right! I'm going to give us an explanation anyway today!"

"We are also human emperors, but we are like pigs and dogs in this cave world, you still want us to miss your kindness?

"A few fellow Daoists, I think this Huang Ting is simply a demon to confuse the public, he is already a demon cultivator, I am afraid that he has already been in collusion with the demons in the outside world, and he trapped us here with that Xia Qianji, there must be another plan!"

Several people roared angrily, and Lu Xuan heard it clearly.

This Huang Ting is actually a demon cultivator?

Lu Xuan opened his Nine Heavenly Eyes to look, and sure enough, he saw that the demonic aura was rolling behind the Yellow Court, and there was a huge figure of red gold winding and circling, covering the void on one side.

His heart shook suddenly.

How could that huge crimson golden figure look like a golden dragon!?

Yun Zhenyue once said that when the Holy Ancestor appeared in the Shaojiao World since ancient times, in addition to the three-legged Golden Crow clan by his side, there was also a divine dragon guarding him. Therefore, it is very likely that there is a dragon clan in this young prison world, could it be that this Huang Ting is the dragon clan?

He looked at the Huang Ting in shock, and the more he looked at it, the more determined he became.

There is also the person named Xia Qianji, who can maintain this cave world, and it is impossible to think of it without spells, so it can be seen that Xia Qianji must be the predecessor of the Heavenly Machine Gate.

Lu Xuan felt his blood boiling, and he couldn't wait to look up to the sky and roar.

The person he had been looking for for more than two years was in retreat in Naxiong Mountain. Even the Shenlong clan has revealed clues, which is simply a double happiness.

However, it seems that Xia Qianji and Huang Ting seem to be in some trouble.

At this time, Huang Ting's expression was completely gloomy.

"Flame Monarch, you are here today, are you the five of you meaning yourself, or are you the Human Emperor who represents the entire Cave Heaven World?"

The Flame Monarch said loudly: "Do you think that the relationship between us and the emperor is very good? In the past hundred years, because of the matter of the Immortal Stone, many of our Daoists have turned against each other. Today's event is the meaning of the five of us, and it has nothing to do with the others! But in any case, you have to give us an explanation. Either hand over the immortal stones, or open the cave world, let us out!"

Huang Ting seemed to breathe a sigh of relief, and then looked at the Flame Monarch with contempt.

"I really feel worthless for Xia Daoyou. ”

"In this Cave Heaven World, there are more than 100 Human Emperors, which one of them was not saved by Xia Daoyou with all his might? If it weren't for Xia Daoyou, you would have died a long time ago without a place to be buried. Now, you actually say that Xia Daoyou has bad intentions?"

"Hahaha! Born to be human, is that what it is?"

The more Huang Ting spoke, the more angry he became, and suddenly he raised his head to the sky and let out a long howl.

The huge dragon roar suddenly resounded through the heavens and the earth.

Suddenly, Huang Ting turned into a golden light and rose into the sky, revealing its original form above the sky.

It was indeed an incomparably huge golden dragon that was dozens of miles long!

Flame Monarch and the others were stunned for a moment.

"Dragon!?"

"How can it be a dragon? Is there really a dragon remnant in this world?"

"We only know that he is a demon cultivator, but ...... But he's a dragon?"

Several human emperors were originally still majestic, but when the golden divine dragon appeared in mid-air, they were immediately confused.

In mid-air, the divine dragon roared: "In the past few days, you have come to harass you three times and twice, and I have tried hard to persuade you, but you are aggressive, don't blame me for ignoring Xia Daoyou's instructions and directly killing you!"

"Ungrateful people like you should never be in this world!"

Huang Ting roared angrily, and suddenly opened his bloody mouth, spewing out a red-golden dragon flame.

The dragon flame was overwhelming, covering the void, and in the blink of an eye, it fell on the head of the Flame Lord and the others.

Although the Flame Monarch and the others are human emperors, they are only human emperors in the cave void period, which is quite comparable to the ten-rank demon emperor. Facing Huang Ting's angry Long Yan, he didn't even have a chance to dodge.

"Spare your life!"

The most irascible and domineering Flame Lord was the first to cry out loudly.

Not to mention that Huang Ting refused to give up, even Lu Xuan showed a disdainful gaze.

Xia Qianji tried his best to provide them with a place to settle down, but they didn't know how to be grateful, but forced Xia Qianji to take out the immortal stone. This kind of wolf-hearted thing deserves to be killed by Huang Tingzhen.

And at this moment, from the Heavenly Peak of the Cave, a sigh suddenly came.
