Understanding of fantasy aura and spiritual power

Reiki is natural, a kind of resource gas floating between heaven and earth.

Spiritual strength is the internal circulation energy formed by absorbing the aura of heaven and earth through breathing and then transforming through spiritual cultivation.

Reiki can't be used directly, it must be transformed first. Of course, there are some exceptions. For example, innate spirits can use gas fields. If the master of a world exists at this level, you can do anything directly with the aura.
