Hidden Realm

Outer-sect odd-jobber Qin Sui is at the third layer of Qi Refining, known as "Qin the Good-for-Nothing." No one knows this is his third life of cultivation. In his first two lives, he reached the peak of Nascent Soul.

Cultivation realms: Qi Refining (thirteen layers), Foundation Establishment, Core Formation, Nascent Soul, Deity Transformation, Void Refinement, and Dao Integration. Demonic beasts are ranked from first to seventh tier.

- Common knowledge in the cultivation world: Lifespans increase with one's realm. Qi Refining cultivators live 120 years, Foundation Establishment cultivators 200, Core Formation cultivators 500, and Nascent Soul cultivators a thousand. No one escapes old age.

- Heavenly calculations: Those at Core Formation and above can divine cause and effect. Thus, "hiding" is more important than "fighting."

- Ancient secrets: All the spirit veins in the present age were formed when ancient great powers used living beings to suppress baleful earth energy. There are seven main veins (a hidden thread running through the entire story).
