At the other end of the Divine Abyss Sea Region lay an incomparably gloomy sea of darkness.
It was filled everywhere with lava and baleful fiendish qi, and even the seawater was black in color.
"One of the seven seas of the Sky-Pillar Immortal Domain, the Nether Abyss Purgatory Sea?"
Chen Nianzhi murmured inwardly, a thoughtful glint flashing through his eyes.
It was said that devil cultivators ruled the Nether Abyss Purgatory Sea. Its cultivation environment was even harsher, yet it was richer than the West Qi Divine Abyss Sea. Correspondingly, there were also more powerful experts within the Nether Abyss Purgatory Sea.
As far as he knew, the Nether Abyss Purgatory Sea had no fewer than seven great grotto-heavens, including devil cultivator grotto-heavens, unorthodox grotto-heavens, and evil sect grotto-heavens.
Prison Suppressor, whom Chen Nianzhi had befriended in the past, was a disciple of Purgatory Grotto-Heaven, ranked second among the seven great grotto-heavens of the Nether Abyss Purgatory Sea.
Heaven Abyss Daoist, standing beside him, noticed Chen Nianzhi's expression and followed his gaze.
Seeing that he was looking toward the Nether Abyss Purgatory Sea, he furrowed his brow slightly and said, "In recent years, the Nether Abyss Purgatory Sea has grown increasingly chaotic, and its strength has grown greater as well."
"I heard that the seven great grotto-heavens of the Nether Abyss Purgatory Sea had actually joined forces to drive out the Demon Court, Divine Court, and Immortal Court."
"So lawless and unrestrained—it will likely become a grave calamity for the Sky-Pillar Immortal Domain in the future."
Chen Nianzhi's brow tightened slightly at those words.
The Nether Abyss Purgatory Sea was the place where an ancient devil had fallen. Legend had it that the ancient devil had stood with one foot already across the threshold of the Golden Immortal realm.
