The Supreme Demon had lost his trace, and the existences under his command had not entirely disappeared. Many Asura Demons began to set up their own factions after losing their immediate superior, and the other existing under the command of different Supreme Demons did much the same.
The remnants of the human race in the Mortal Realm thought about competing for supremacy, while the servants of the Supreme Demons in Hell aspired to compete for "supremacy" to obtain the position of a Supreme Demon.
Even though the Supreme Demon still had a lingering power, many of his servants dared not disobey their former boss, but they could choose to follow the remnants of other Supreme Demons. Thus, continuous conquests plagued Hell, making it utterly chaotic.
And this kind of chaos would not subside for several decades or even hundreds of years. Recently, the conflicts had become even more intense, all because of something like the Corpse Demon.
