Spiritual Roots were exceptionally rare resources, especially for Martial Arts Strongmen who had just established their Inner Heaven and Earth, or those who were about to.
A Spiritual Root had the power to stabilize an Inner Heaven and Earth, or a Secret Realm.
Currently, most Martial Arts Strongmen referred to their Lifebound Inner Worlds as Secret Realms, unlike in later eras when they would be called Inner Heavens and Earths.
Secret Realms were divided into several stages: Newborn Secret Realms, Small Secret Realms, Medium-sized Secret Realms, and Large Secret Realms.
A Newborn Secret Realm was like an infant, possessing nothing at its birth. Typically, a newly born Secret Realm would be just a stretch of yellow sand or an expanse of seawater—monotonous and devoid of Vitality.
