Wang Jianru once gave Ye Qingyu a piece of Northern Jade, which contains the mystery of time, and in the ancient bronze book [God and Demon Title Spectrum], there is also a technique, called [Ancestor of Time], which is also an imperial technique to manipulate the law of time, and Ye Qingyu has dabbled in it.

Before, with the Bright Emperor Derivation Technique, Ye Qingyu used that tile as a medium, and finally found the disappeared ancient city, which existed in the double turbulence of time and space, and the location was extremely hidden, no wonder Ye Qingyu couldn't sense it before.

Ye Qingyu had already sensed the aura of the disappearing Chaos Ancient City.

As for whether Nan Tieyi and Hu Bugui are among them, it is uncertain for the time being.

But Liu's inference is undoubtedly very reasonable.

However, what surprised Ye Qingyu was that in the Chaos Ancient City that he deduced, he felt a somewhat familiar aura, which had been seen on the body of the White Bone War Beast Xiao Shi, so at the moment of departure, Ye Qingyu summoned the White Bone War Beast Xiao Shi.

Xiao Shi appeared in front of Ye Qingyu in an instant.

Thousands of years have passed, and its cultivation is still at the peak of the Quasi-Emperor Nine Heavens, and it has not really entered the Emperor Realm, because it is limited by its origin, Xiao Shi belongs to a kind of parasitic creature, and can only rely on continuous devouring to improve, what kind of realm does it want to cultivate, what kind of existence needs to be devoured, and in the past two thousand years, there is no Emperor Realm powerhouse that can be devoured, so it can only end here.

"The hosts. ”

Xiao Shi saluted Ye Qingyu respectfully.

Ye Qingyu nodded, then looked at Liu Killer and said, "Let's go." ”

The voice fell.

A ripple-like spatial ripple flickered, enveloping the three of them, and in a flash, they disappeared into the original space.

......

......

"This is the vanished Chaos Ancient City?"

The figures of Ye Qingyu and the three of them appeared in a vacuum like an ocean tide, the torrent of time and space was whistling, and the power of various laws was extremely unstable, even if they were strong in the Emperor Realm, in such an environment, they were afraid that they would be carried and lost, an extremely terrifying and terrifying environment. If there is no Ye Qingyu, I am afraid that Liu Killing Ji and Xiao Shi will not be able to gain a foothold in such an environment at all, just like a person who is not good at water falling into the ocean, he will be swept away and drowned.

Ahead, a black castle appeared in the sight of the three of them.

It is a dilapidated ancient castle, the whole body is made of black rock, the texture is rough, the surface of the black stone is full of pitted depressions, there are knife marks, sword holes, and traces of axe and hammer smashing, about 100 meters high city wall surrounds the entire black castle, looking beyond the city wall, you can see a strange tower-like building towering high, surrounded by a giant black tower thousands of meters high in the middle, like a sword piercing the void.

The whole black castle gives people a sense of the vicissitudes of ancient times.

"I wonder if there are any residents in the castle?" Liu Jiji's heart was full of curiosity.

He hoped to see his long-missing brother inside.

"I felt a kind call, and there was my kind in this castle. Xiao Shi's expression became excited, it couldn't break through for a long time, its strength couldn't grow, and it would feel lost and trapped in its heart, but the moment it saw this ancient castle, it seemed that some memories were awakened, and it vaguely felt something.

"Go in and have a look. ”

Ye Qingyu took the two of them, separated the turbulence of time and space, and hurried towards the black castle.

Suddenly, the three of them came to the gate under the ancient castle.

Looking at this black castle up close, you can see its grandeur and majesty more and more, even bigger than the Tongtian City where the headquarters of the Realm Alliance was located in the past, ordinary people standing under this black city wall, standing at the gate of the city, like an ant standing at the door of a rat hole.

"It's a sign of fire. ”

Liu Jiji stretched out his hand to caress the black city wall and felt a scorching breath.

"Indeed, it is the traces left by the emperor's fire...... The entire ancient castle has been burned by the extremely terrible fire of the Emperor's Road, and its original appearance is definitely not black, but because it is burned, it will leave such a color. Ye Qingyu was extremely sure of the authenticity, with his cultivation strength, he could naturally see it at a glance.

Obviously, there were tragic battles inside and outside this black castle, and it was a battle between emperors.

Ye Qingyu deduced and felt a lot of familiar breath.

He probably already knew what kind of battle was going on here, and even who the two sides were.

Liu Jiji stretched out his hand to push the gate of the ancient castle, but he did not move, and his operation of Dili could not work.

Ye Qingyu's eyes swept and the door opened.

The three of them entered the gate, behind the city wall, there was a zigzag main road, also black, there were no plants in the city, not even living creatures, everything was pitch black, the color was depressing and weird to make people feel dull, the street was not very wide, but it was very distinctive, the whole castle gave people a feeling of being built against the mountain, most of the roads were winding, with steps, getting higher and higher from the bottom to the top.

Ye Qingyu swept it at a glance, and probably everything in the entire castle was clear.

Within the city walls, everything was clearer, which more and more confirmed Ye Qingyu's previous guess.

The strength of Liu Killing Chicken and Xiao Shi was too far away from Ye Qingyu, and they didn't perceive too many clues.

Ye Qingyu led the way in front, and everyone walked up a winding black stone road, all the way up, towards the highest sword-type tower in the center of the ancient castle, he had already found some noteworthy signs, if Nan Tieyi and Hu Bugui were really in this ancient city, then they could only be in that place.

Along the way, all kinds of battle traces were seen.

There are traces of the Emperor's fire everywhere, back then, after the end of the battle, there was a sky-high fire burning here, and it took a long time to turn this ancient city black, but even so, the Emperor's Fire failed to incinerate this ancient castle, which shows that it is extraordinary.

"The material of this castle is exactly the same as the tiles of Nadi. Liu Jiji observed along the way and finally came to such a conclusion.

He was shocked.

Ye Qingyu smiled and said, "Yes, the tile in Brother Hu's hand should have been lost from the tower of this ancient castle, and this ancient castle itself is an amazing imperial weapon...... The twenty-four cities of chaos, it is rumored that they were all built by the Supreme Emperor, and this ancient castle is no exception, its power is still on top of Tongtian City and other cities, and the person who built it back then must be an incomparably powerful martial arts emperor, and even vaguely touched the realm above. ”

Along the way, there was silence on all sides.

There was no living creature in the castle.

"The two brothers, Hu Bugui and Nan Tieyi, are they here?" Liu Jiji was a little anxious, this was the last hope to find the two.

While speaking, the three of them came to the entrance of the gate of the highest sword tower.

Here, it's a little different from other places.

"If I'm not mistaken, they're in there. Ye Qingyu smiled, stretched out his hands, and the fluctuations of the eternal power were imprinted on the gate.

The door of the Sword Tower slammed open.
