- The universe is divided into five major realms - Mortal Realm, Immortal Realm, Divine Realm, Hongmeng Realm, Chaos Realm and Taichu Realm. Each realm has its own unique laws and rules of heaven and earth. The mortal world is the lowest level, with thin spiritual energy, and the strongest is no more than the Nascent Soul; while the Taichu world is the place where all things originate, containing the power of creation, and only those who break through the shackles of chaos can enter. All realms are separated by "boundary walls" and can only be crossed through the "Road to Heaven" or "Realm Gate" left over from ancient times. The key to unlocking the realm gate is the "Ancient Jade from the First Age" awakened in the protagonist's body.
