Spiritual Power.
Ye Tian suddenly thought of this term.
In this Plane World, you can see many Heavenly Materials and Earthly Treasures everywhere.
On Earth, many materials considered important are quite rare, yet here, many people don't understand them.
The technological civilization here is as developed as on Earth, but in medicine, there's only Western medicine, without the concept of Chinese medicine.
Ye Tian was originally thinking about cultivation and such things, but now having so many natural resources and various herbal medicines has greatly enhanced his hopes for cultivation.
Various high-quality herbal medicines, as well as Heavenly Materials and Earthly Treasures, are all essential for cultivation.
Moreover, when Ye Tian was collecting herbs everywhere, he accidentally discovered that the air in these herb-gathering places is particularly good.
To be precise, it should be some strands of rejuvenating Spiritual Energy.
