In the Cross Realms fantasy harem game, you and a group of friends are unexpectedly pulled into a swirling vortex on your first day of college. When you regain consciousness, it becomes clear you're in an unfamiliar place that is not Earth. As you explore this strange new world, you uncover that it's a Qi cultivation realm where power rules all. The universe is divided into nine Realms, each governed by a powerful race-Humans, Demons, Deities, Spiritual Beasts, and others. Every Realm draws its power from a "spring," a source of Qi energy collected from the Void, the mysterious space separating these worlds. These springs are the key to power, and the fragile peace between the Realms is often short-lived. You arrive during the longest period of peace ever known, but how long can this uneasy balance truly last? As your journey unfolds, you unravel hidden secrets about the Realms. Someone has been pulling the strings, orchestrating your arrival from the shadows. In a world where you're viewed as little more than an insignificant ant, will you find the strength to rise and defend yourself?
