In the dark waters of the Lost World.
The Oppressive Tyrant, Baal, had met with the forces of the Cultivators as they made their way towards the city of technology and magic. It was an oppressive force that was spreading throughout the sea as they came across empty underwater cities with the Merfolk and the Atlanteans already evacuated. Anything of value like weaponry or any advanced technology was already taken along with the evacuated inhabitants.
The Demon Legions left nothing in their wake as they destroyed anything they came across and searched the cities in the entirety. Their goal remained the same as they looked like a sharp spear that was aimed towards Atlantis.
