Primordial Era: Reborn as Kunpeng, starting by swallowing the Styx River

In the primordial world, Kunpeng, a being from a higher realm, finds himself transmigrated to a time shortly before the Dragon-Han Tribulation. With a bleak future awaiting him as a demon master, Kunpeng sets his sights on the Netherworld Blood Sea to obtain the treasures he lacks. He decisively swallows the consciousness of the Styx River before it awakens, claiming its place as the Northern Underworld Overlord. As the new Styx Ancestor, Kunpeng prioritizes accumulating strength over seeking fame. On the surface, he appears to be a diligent worker in the Heavenly Court, crafting demon script for the demon race, while secretly manipulating the script to harvest the souls of countless demons. Additionally, he creates Asuras, disguising his true intentions behind a façade of cooperation.
