[Demon Book]
A supreme treasure born from the unique system of world S-01,
Initially, during the early days of the world's inception, the Black Tower attempted to replicate the Demon Book, but all efforts failed... It was later confirmed to be an exclusive product of S-01, and only entities as extreme as Demons had the potential to read and cultivate it.
To other creatures, the Demon Book was more potent than poison.
These Demon Books were not personally created by any ancient Old King, but were closely related to the chaotic essence of the world.
Their origins were mostly unknown.
When they were discovered, they often had already taken an entire civilization,
or had transformed an unknown planet into a highly dangerous [Forbidden Land] that could threaten the Demon Group,
or when they were written, they directly stripped away the entire planet and nearby space, exiling it to a spatial gap until it was accidentally spotted by an Old King,
