A medicine garden is different from a spirit field, as it doesn't require a perfectly flat surface.
In fact, it can be created even in the rugged mountains and forests, needing less space than a spirit field.
Therefore, the mountain valley that He Song was in naturally became an ideal place to build ten medicine gardens.
The main reasons were
that the valley was large and well concealed.
From the outside, it was inconspicuous.
It only required setting up a Miniature Spirit-Gathering Array, a Smoke Array, a Seven Kills Heaven Fire Array, and a Sea-Stabilizing and Spirit-Orienting Array in the valley.
Doing so would completely envelop the valley, concealing the medicine gardens and keeping them from being discovered by others.
This would also allow the gardens to resonate with the hidden cave mansions nearby.
In case any unforeseen circumstances occurred in the future, He Song could obtain substantial benefits from these ten gardens after arriving at this location.
