A floating city, even a fallen floating city, is still more terrifying than most mage towers. There is no doubt www.biquge.info that the challenge level of this floating city ruin is higher than the Mage Tower of the Fire Lord, and higher than the Mage Tower of the Blue Lord.

An intact floating city often requires a demigod squad to be eligible for the challenge. Even if this floating city has crashed, Gavin estimates that there are still intact parts of it, so its horror is still not something ordinary people can imagine.

"Since you're here, let's go in and have a look." Gavin was not afraid, because the Lord of the Eternal Night had been to the floating city and knew the basics of what was going on.

In fact, unless they were willing to spend hundreds or thousands of years, it would be difficult for even a legendary mage of the level of the Eternal Night Hades to build a complete floating city.

Not to mention, Desdir is not a great alchemy master in the true sense of the word.

At the time of the construction of the Seven Underworlds, the Lord of the Eternal Night already had a group of mages of more than a thousand people. With the help of those mages, it took him a long time to complete the construction of the Seven Underworlds, and then it took the rest of the time to slowly improve it.

Floating City didn't come into existence until the Arcane Empire era.

In fact, in the higher eras, there were also floating cities. It's just that the floating city at that time was really just a city floating in the sky, and it was not even as good as a slightly better mage tower. It was only in the Arcane Empire era that the Floating City truly rose to prominence as an imperial powerhouse that could rival the web of magic towers.

The tomb of eternal life, the city of the dead.

In the era of the Arcane Empire, among the alchemists standing at the highest peak, only the Lord of the Eternal Night was studying necromancy. Therefore, when building the Tomb of Eternal Life, Desdil, who had a good relationship with the Lord of the Eternal Night, sought the help of the Lord of the Eternal Night.

Aside from the really crucial parts that can't be known to anyone, the Lord of the Eternal Night has a basic understanding of the floating city, so Gavin also knows a basic one.

The most important building in the Floating City is the Seven Psychic Towers, which are the mage towers of the necromancers. One of the tallest is the Psychic Tower of Destir himself, and then the six Psychic Towers around it, located in the six corners of the Floating City, belong to the six legendary necromancers.

Those six necromancers, although far inferior to Desdil, are at least stronger than the Forgotten Mages in this era.

In addition to the seven Psychic Towers, there are more than a dozen buildings with different functions, such as the Death Knight Temple, such as the Lich Necropolis, such as the Crypt of Death, and the Burial Ground for the Frost Dragons and Bone Dragons.

And outside of these buildings, there is a square, the only square of the Tomb of the Immortals.

In the center of the square, there is an altar: the Altar of Eternal Life.

Undead creatures are called "undead" because they have escaped the realm of mortals and have eternal and immortal lives, and the Altar of Eternal Life, which is an altar specially prepared for undead creatures, is also an important building in this floating city, second only to the seven psychic towers.

It's right in front of Gavin's eyes.

Walk through the gate and you'll find the square.

There was gray mist everywhere here, it was extremely rich death energy and undead aura, covering the eyes and perception, even with a legendary-level spiritual perception ability, it was difficult to pass through the barrier of the fog.

There is no doubt that the effect of these gray mist is similar to that of the deepest part of the Misty Array.

In the distance is the Altar of Eternal Life.

This altar is about ten meters high, and when viewed from the sky, it looks like layers of perfectly nested hexagons, and each side of the outermost layer is about fifty meters long.

It was a very large seven-story altar of the undead, which had been destroyed.

A large rift split it in half, and the dense energy of death that could not be dissolved gathered in it, and then there was ...... Evil energy!

Evil energy from the abyssal hell!

It was a demonic aura, and it was very strong and powerful, locked by this altar, firmly locked within the altar range, only a very small little bit permeated into the tomb of eternal life, but it did not permeate outside this floating city.

"Abyssal Rift!" Gavin said quietly, extremely cautious in his heart, and a little ...... Expect.

Here, there is an abyssal rift, a rift leading to the abyss hell!

In other words, on the other side of this rift, is the abyss hell!

There are not many known abyssal rifts in the Continent of the Gods, and each one is guarded, blocked, or directly sealed.

For example, the abyssal rift below the Death Swamp was guarded by Teacher Prespo and Andus, the Lord of Flames, and a large number of mage groups were sent to set up magic arrays to blockade them, and even His Excellency the Great Guardian directly sent mage groups to garrison them.

Because every abyssal rift has the potential to become the entrance for the Abyss Hell to invade the Continent of the Gods again!

Here, too, there is an abyssal rift.

And looking at the rift on the altar of the undead, this abyssal rift seems to have existed for a long time, I don't know how many years it has existed, the rift has been rotten around it, it has been seriously eroded by the demonic aura, and it has even been transformed into a demonic material.

This altar of the dead is slowly being transformed into a demon altar, and judging by the situation, the transformation has been carried out more than halfway.

If no one interferes, maybe it won't be long before this altar will completely turn into a demon altar, and then countless demons will come to the Continent of the Gods from here and invade the Continent of the Gods!

"Those Death Knights are probably the keepers of this altar. The owner of this floating city, can't he reverse the transformation? Or...... Has it fallen into the arms of demons? ”

Gavin's speculation was not without reason.

In fact, he looked closely and found that this altar of death, guarded by a terrifying force, could not be approached by ordinary people at all, not even legends, at least Gavin wanted to get close, it was very difficult, let alone walk up to the altar.

If he had to go to the altar, he would be attacked by terror, and Gavin didn't have the confidence to hold on.

An altar of death, actually defending against the outside, why is this?

"All this should have nothing to do with Desdil. The appearance of the Abyssal Rift is likely to occur during or after the War of the Gods. On this mysterious island, there is actually a Barlow Flame Demon, so why can't other demons appear? Perhaps, in this floating city, there is also some more terrifying abyssal demon hidden? ”

Gavin didn't dare to be careless, he found that the floating city was locked in a fog and could not see the truth.

"Well, take a look around."

Gavin shook his head, then took a step, heading farther afield.
