This is where Molten Fire City of the Flame Sun Association is located.
Molten Fire City.
Though called a city, it's actually not a castle built inside the Molten Lava Cave. Inside the Abyss of Eternity, there is almost no place where one can linger long. Once one stays for a long period, a constant emergence of Abyss Beasts is inevitable, transforming into a massive beast tide!
When evolved to that extent, even Divine Monarchs of the Nine Layer Heavens would find it difficult to escape.
Therefore,
In the Abyss of Eternity, all living beings must keep moving continuously.
Molten Fire City is actually an Upper Divine Weapon akin to the Fan Gu Palace refined by Fan Gu Divine Monarch!
It floats over a Molten Lava Cave. To the naked eye, it seems merely a model of a city, just a few meters in circumference, appearing very petite. But, in reality, it contains the Mystical void Lineage, Sumeru Mustard Seed.
