Life Bank and Life Courtyard belong to the "Earthly Divine Kingdom," but in the end, they are still a piece of "Secret Realm," a Land of Life that forms its own little world.
The Land of Life cultivates and nurtures life, while also needing life's feedback and life cycle to perfect itself.
New species and new forms of life are the "foundation" for the Land of Life, serving as the basis for its increasingly complex biological community.
Initially, when the Lady of the Forest's Secret Realm requested new magic plants from Lu Ping'an, their combat effectiveness was essentially zero. But considering their "sample significance," their value was not insignificant. No wonder she offered a treasure that could be compared to "Life-points."
What's important is not the quantity, but the "variety" and the biodiversity and possibilities it contains.
