In this barren desert with scarce spiritual energy, cultivating a spiritual herb garden is quite a troublesome task.
First, you need to find a place where time flows faster, then guide the surrounding spiritual energy to irrigate the area, constantly keeping an eye on it to ensure nothing goes wrong.
Once the spiritual herbs mature in the accelerated time flow, you must pick them immediately, and you can't even pick them yourself; everything consumes true essence.
The key issue is that with the thin spiritual energy here, recovering true essence is troublesome.
