The cultivation techniques obtained from the Underworld were vast, numbering at least in the hundreds. Many of these were in the native Two-Faced language, involving different bodily meridians, so Lin Xin couldn't directly start practicing them without continuous adjustments.
He only needed the key principles and creative ideas, along with many detailed descriptions inside. Especially the extremely detailed descriptions of the stages after Foundation Establishment Stage, even the Golden Core Stage, Nascent Soul Stage, and the final indescribable realm.
By reading extensively, Lin Xin gradually also had a complete division of the entire cultivation realms, as well as an understanding of higher-level cultivators.
Having read too many books, especially ones that ordinary people and cultivators could not amass, Lin Xin, despite lacking practical cultivation experience, had knowledge comparable to many Taoist Master level cultivators.
