The Purple Light Jiaolong's Inner Dan and Ye Yu's Yuan Shen fused together without any accidents, perhaps because he already had some of the Purple Light Jiao Dragon's Yuan Shen, so it would be so smooth.

However, now he has no way to do the experiment, he can only wait until he goes out, and he has time to try it again, and his Yuan Shen has not changed at all, if there is any change, that is, his Yuan Shen is much more condensed than before swallowing Neidan.

After some excitement, all the loot was collected into the Xuanhuang Ring, and Ye Yu had to look at the huge palace again, if it wasn't for the use of the immortal pupil, he wouldn't be able to see the direction of the palace at all.

It is already inconceivable that a river formed by a river of fire comparable to samadhi can be built, and it is even more incredible that a temple of such scale can be built at the bottom of the river of fire, like a dream.

Ye Yu first replenished the consumed Xuan Qi before slowly walking towards the palace, in this dark place, he couldn't feel the passage of time at all.

Night Feather felt that he had walked for nearly half an hour, but that temple was still not far from him, and the eternal distance made him think that he had seen the legendary mirage, but compared to half a day ago, that temple had slowly materialized a lot, at least it would not be like at the beginning.

After being less than ten steps away from that temple, Ye Yu could no longer see the appearance of that temple clearly, even if it was an immortal pupil, it was useless.

Night Feather's eyes showed a deep groan, and then, with a wave of his right hand, a golden flame suddenly came out of his hand. It hits the surface of the building like a fan. Then it exploded.

"Boom~~-"

The deep voice kept echoing.

And the surface layer of this underwater building is muddy. was also shocked and thrown up by the strength of the Xuanyang Fire Explosion. Suddenly, the surrounding waters were muddy, but in this murky water. Nightfeather was close to the surface of the underwater building. Take a closer look

"What kind of material is this? turquoise walls. ”

Night Feather was dumbfounded.

"It's incredible. I don't know how many years have passed under the tremendous pressure of the cold water at the bottom of the lake. There was no scar on the wall. ”

"Moreover, the wall turned out to be monolithic. It's not built in pieces. ”

"I can see it as far as my eyes can see. There are walls nearly ten zhang wide. But the whole wall turned out to be one. Turquoise walls, not stone. Not steel. What the hell is this?"

Night Feather felt the monstrous waves in his heart, as early as when he was fighting with the purple light dragon, he had already seen this palace, but at that time, he saw a blue palace, but he didn't expect to look at it in front of him, only to find that it was a palace formed by a huge stone, and everything was like a dream.

When the spiritual sense he looked at swept over the three ancient characters on the giant door, three fonts that he could understand appeared in his mind.

Reincarnation!

"Hall of Reincarnation!"

No one knows how many hidden powerhouses there are in the Demon Realm, but the people from the Xuanwu Continent know one thing very clearly, that is, there are many sixth-order powerhouses in the Demon Realm.

For thousands of years, the names of groups of strong people in the Demon Realm have been powerful in all directions, and their names and titles have been recorded in the history of the Demon Realm, and some of them have been comparable to the existence of gods.

The names of those people were even widely spread in the Xuanwu Continent, and many people from the major sects knew which masters in the Demon Realm existed.

Counting the strongest in the history of the Demon Realm is two thousand years ago, the Four Demon Realms!

Those are legendary beings.

The four deities of the Demon Realm are;

Blood Luo, a body of cultivation above the Demon Shuai, is said to be the existence of the Great Perfection in the late stage of the Sixth Order, and now his whereabouts are unknown, some people think that Blood Luo has died, and some people think that Blood Luo is in a dead pass, in order to go further.

The second legendary character in the Demon Realm is;

Shura, no one knows its name, but they know that this is a Tianjiao who has been famous in all directions as early as 2,000 years ago, and it is also a demon cultivator who kills people without blinking, a real demon cultivator, so he will be respectfully called, Shura!

The third legendary character in the Demon Realm is called, Nightmare!

A person who makes people smell and change color, no matter who it is, as long as they see the nightmare eyes, they will involuntarily fall into a fantasy world, unable to extricate themselves, and it is an existence that makes people feel hopeless.

The fourth character is the ancestor of the city lord of the Demon God City, this is a person like a fan, but he knows that his cultivation is profound, as early as two thousand years ago, he has been crossing the saint tribulation, and now more than two thousand years have passed, if this legendary figure is not dead, he must have become a strong man at the level of the saint king, there is no doubt about it!

The four deities of the demon world disappeared from the demon world at the same time period, and no one knows what happened, but it is rumored that the four deities of the demon world have been cut to death because they have touched the forbidden things, but everything is just a mystery, an unsolvable mystery that has been circulating in the demon world for more than 2,000 years!

However, there is no doubt that the terrifying nature of the Four Demons is deeply rooted in the hearts of the people, and the aborigines in the Demon Realm are deeply aware of the strength of the Four Demons.

Although the Demon Realm is now ostensibly the city lord of the Ancient God City leading the Demon Realm, there are also many lurking forces in the shadows, and they are all waiting for the return of the king in their hearts.

Even if it is the county guard of the Nine Counties, it may be the people of the Blood Luo, or it may be the remnants of Shura or Nightmare.

The legends handed down from the Demon Realm record that it has been more than 2,000 years since the Blood Luo, one of the four deities of the Demon Realm, disappeared near the Fire River.

How terrifying Blood Luo is, Ye Yu didn't know, these were all things he had heard about when he was in Qinghe County, but he could feel that this person named Blood Luo, if he didn't die, would definitely be a supreme existence.

When those three ancient and simple fonts appeared in Night Feather's heart, Night Feather became a little excited.

"It's really nowhere to find it. ”

Night Feather has been in the Demon Realm for some time, but she hasn't gotten any information about the Reincarnation Palace.

Who would have thought that I would see the Hall of Reincarnation here?

"My Heavenly Soul is here. Ye Yu was also a little uneasy, he was worried, he was afraid.

What Ye Yu is afraid of is that more than an era has passed, is Sun Wukong's heavenly soul still in the Hall of Reincarnation?

"No, Hui Hai once said that the four deities of the Demon Realm may not be dead, and it is possible to live in some unknown space, could it be that there is one of the four deities of the Demon Realm in this palace?"

Collecting all his thoughts, he looked at this huge hall of reincarnation, the more he looked at it, the more frightened he became, and finally his two eyes turned into a black dot, he knew the material of this palace!

"Hmm, no, this is not just the Soul Stone, it's also a whole Soul Stone!"

After looking at it for a long time, Ye Yu was able to see what kind of palace this was, a huge palace completely condensed from the Universe Soul Stone.

The height is at least 100 zhang, and the width is at least 80 zhang or more, it is impossible to imagine that if he hadn't seen and touched the Yu Soul Stone from the memory of the soul piercing the eternal burial, he himself would not be sure that the so-called reincarnation hall was actually made of the Yu Soul Stone, no wonder it was immortal.

"Is this the best Xuanling Stone in Hua Qianmei's mouth?
