Theoretically speaking, Jade Immortal itself is a kind of cultivation resource.
Having consumed countless Heavenly Materials and Earthly Treasures, spent innumerable Immortal Stones, and absorbed endless energy from heaven and earth, it can be considered a humanoid, beast-shaped Immortal Elixir!
If Shi Hao were to eat people, he definitely wouldn't do it, but when it comes to Ferocious Beasts, he has no psychological burden.
Would using Jade Immortal as a cultivation resource be feasible?
Well, an Immortal Realm has only about a hundred Jade Immortals. Killing them all might not even allow one Jade Immortal to improve their cultivation by two stars. Furthermore, a Nine Stars Jade Immortal has already reached the pinnacle and does not need to hunt other Jade Immortals as cultivation resources. Additionally, lower-level Jade Immortals are not qualified to hunt higher-level Jade Immortals.
Moreover, an Immortal King would not allow such cultivation methods to exist.
