The Reverse River is a legendary Heaven Earth Secret Realm, as renowned as Soul Cleansing Mountain, Luopo Valley, Lake of Enchanting Souls, Book Mountain, and Market Streets. Like Market Streets, the Reverse River is a Heaven Earth Secret Realm of Rhythm Tao—a treasure of the world.
The exact time these Heaven Earth Secret Realms first appeared is unknown. However, they have greatly enriched the cultivation landscape of the Martial World, each representing the pinnacle of its respective school.
A cultivation school's potential can often be gauged by examining the Heaven Earth Secret Realms associated with it. In a way, the existence of these Secret Realms also indicates which schools are more formidable—those that have produced a Great Emperor or possess the potential to do so.
In the absence of a ninth-grade Emperor Artifact, a Heaven Earth Secret Realm is, without exception, the most significant means of amplifying combat power.
