[It does exist, but it's not detailed]
[It only describes the terrifying aspects of the Soul-Eating Gu, just like what Liu Cheng'an said]
[It indeed hides within the Ruins Secret Realm, so much so that even several years later, when the male and female protagonists executed the Little Antagonist in the Ruins Secret Realm, they never encountered such disgusting things]

[Impossible, the headquarters... the headquarters didn't say anything]
The Old Sixth System replied, starting to feel uncertain itself.
[Or maybe, this isn't a transmigration into a book at all but a real world]
Lu Xingyan said something startling.
[No... no way!]
The Old Sixth System stuttered: [If you didn't transmigrate into a book, then what am I? How would I know the original plot?]
[If Yuezheng Yan can be reborn, whether you're a system or not is also up for debate]
