Zhao Rui left the restaurant and flew slowly in the direction pointed by the guy.

While flying, he carefully observed the surroundings, looking for the whereabouts of the Welling Immortal Monarch and the others.

The Welling Immortal Monarch is a high-level spy of the Hades Demon Clan, with a lot of experience, and if he encounters danger, he will leave some clues more or less.

It's just that he searched for a long time, but he still didn't find any marks left by the Welling Divine Monarch.

At this time, Zhao Rui was already far away from the heart of the city, almost reaching the edge, and the residents of Extreme Fog City encountered on the way were getting fewer and fewer.

Whether it is empty or on the ground, it is deserted, and there is no figure to see for half a day.

Occasionally, a fog demon emerges from the fog, and his expression is not good, and his eyes are full of viciousness.

Compared with the splendid giant tower complex in the center of the city, it is very depressed, and the buildings in the line of sight are getting lower and lower, more and more sparse, and the giant towers that can occasionally be seen also seem to be in disrepair, looking dilapidated, and many buildings have cracks.

Zhao Rui was a little suspicious in his heart, although the Mighty Spirit Immortal Monarch came out to understand the situation in Extreme Fog City, why did he come to such a secluded place?

What's the secret worth finding out here?

With doubts, he continued to move forward, and the further he flew, the more remote and desolate he became. In the end, there was no more fog demon, not even a giant tower. Only yīn cold wind, whistling in the low.

Zhao Rui couldn't help but wonder if it was the guy from the restaurant who deceived him.

He slowed down, contemplating whether or not to return.

At this time, the silhouette of several buildings. In the distance, the fog loomed.

These buildings don't seem to be quite the same as the tower-shaped style of Polar Fog City.

It's just that it's too far away, plus it's foggy. The outline is very blurry and impossible to see.

Zhao Rui thought about it, he had already flown so far anyway, but he didn't care about flying another section. So he picked up speed and continued to fly forward.

As he flew closer and closer, the outline of the building in front of him became clearer and clearer.

Those buildings have warped cornices and corners, layered on top of each other. It is somewhat similar to the Immortal Palace Temple of the Immortal Demon Realm outside the Extremely Dark Abyss.

When he arrived, Zhao Rui was shocked by the scene in front of him.

This is a remnant of an ancient Asgard complex.

The ruins occupy an extremely wide area, and the buildings are beautiful and magnificent. As far as the eye can see, there is no boundary.

It is conceivable that at the beginning of its heyday, it must have been a series of buildings and magical sounds. The fog demon comes and goes, and the flag covers the sky.

It's just that the light yīn is like a knife, and the splendor of the past is gently erased.

Only the ruins remained. In the bleak cold wind, the glory of the past is whispered.

The ground is overgrown with weeds. Swaying in the wind, withered yellow vines. Crawling all over the broken walls, the broken jīng beautiful reliefs, quietly covered up.

The dead towering ancient trees still stretch their curved branches to the sky, as if they are making a silent accusation to the sky.

Zhao Rui took a breath lightly, only to feel that between his breaths, there was a desolate and desolate taste.

Quietly looking at the ruins of the Immortal Palace in front of him, a thick cloud of doubt rose in his heart.

The ruins of this fairy palace are very different from the tower-shaped buildings of Extreme Fog City.

The towers of Arctic Mist, while huge and magnificent, are too rugged and lacking in beauty.

The ruins of the fairy palace here, although it has been dilapidated, are jīng carved and beautiful, which is not much better than the palace groups in the fairy and demon world.

In addition, the age of the existence of this fairy palace site seems to be very long, maybe it has appeared since the ancient times.

Didn't the Netherworld Ancestor say that the fog demons of the Extremely Dark Abyss were ferocious and barbaric, and their minds were not opened?

How could such a splendid and magnificent fairy palace be built in the primeval era?

Zhao Rui thought about it for a long time, but he forgot most of the purpose of coming here.

The dripping rain, at some point, fell, hitting the body cold.

The rain was shockingly bright red, sticky, fishy, more like blood.

Zhao Rui's heart rose and he woke up in an instant. His gaze froze, and he looked around.

The white fog was confused all around, and there was a dead silence.

Listening carefully, there seemed to be a low whimper, coming from the ruins of the Immortal Palace in the depths of the mist, and it looked particularly poignant in this empty building complex.

What's there?

Zhao Rui's heart froze, he raised his vigilance, and walked slowly in the direction from which the voice came.

The further you walked in, the deeper the barren grass became, almost waist-high, and there was no life nearby, as if you had come to the realm of death.

As he walked, his feet were empty, and with a "click", it seemed that something had been broken.

Zhao Rui pushed aside the grass and looked down to see that it was a dry bone!

The dry bone fell to the ground, his right arm had been trampled on by him, and the other parts were still intact, and an unsheathed fairy sword was thrown not far away.

It's just that due to the rust of time, this divine weapon has long been damaged and has lost its brilliance.

The suspicion in Zhao Rui's heart is even deeper, the fog demon in the extremely dark abyss and the underworld demon in the netherworld and the void are actually very similar.

They are all tangible and insubstantial spirits, and once they die, they will automatically dissipate, and they should not leave any traces of existence.

In that case, how could there be a dry skeleton left here?

With doubts, he walked forward a little further, and stepped on several dry bones one after another!

Zhao Rui felt more and more that something was wrong, he stopped, waved his hand lightly, and the wild grass in front of him "brushed" and separated to both sides.

A bone-paved avenue loomed out in front of his eyes!

And at the end of this avenue, there stands a huge tomb made of dry bones!

Around the tomb, there stood the dry bones of huge creatures, which were hundreds of meters long, like loyal guards, guarding the tomb.

Zhao Rui was shocked, feeling that the temperature around him seemed to have dropped a lot in an instant, and his body was filled with chills.

One will become famous for eternity.

However, there are far more dry bones here, but definitely more than 100,000, and maybe even hundreds of thousands!

What is the identity of these dry bones?

And what is the reason for such a huge number of them to perish?

And what kind of legendary characters are buried in this bone tomb?

Zhao Rui thought so in his heart, and circled around the giant tomb, observing carefully, hoping to find some clues, but he found nothing, and even the seemingly nonexistent whimpering sound that led him here disappeared together.

Only a few strange birds with black fur stood at the top of the tomb, staring at him with dark red eyes, which made him feel very uncomfortable.

The cause of the formation of the bone tomb was not found, and the missing Willing Divine Monarch and other demons were not found.

Zhao Rui felt that this was not a place to stay for a long time, and was planning to go back.

At this moment, the strange birds opened their mouths and let out a strange chirp like a cry.

Zhao Rui hurriedly turned around, only to see thick black gas emerging from the tomb and sweeping towards him。。 )
