Hmm, a flying toad.
Living Spirit Plants are good for this reason, once they have undergone basic cultivation, they can sever ties with the land, sustained by a cultivator's spirit Qi instead, though most cultivators' spirit Qi is insufficient to meet the needs of these Living Spirit Plants.
Take, for example, this creature, which requires both the pure moon power and the spirit Qi of an earth vein; after all, not everyone has their own world like Song He does.
If you want spirit Qi, you can produce it anytime, anywhere.
Because of this, the Spiritual Leaf Sect also has a business selling "Spirit Energy Packets" that cater to the specific needs of various Living Spirit Plants.
With just a small expenditure of Spirit Stones, you can have an extra follower that is as smart as a Spiritual Beast and utterly loyal. Many cultivators choose to buy one for their offspring.
"Just follow me, and by the way, learn this Cultivation Technique..."
