Historical World: On December 21, 2012, a cataclysm plunged Earth into massive upheaval. With the intervention of diverse factions-including gods, immortals, demons, Buddhas, evil spirits, ghosts, alien races, and remnants of ancient civilizations-this world, now expanded hundreds of times over, did not experience excessive turmoil-save for the emergence of more interdimensional spaces such as floating cities and underground cities. In this new world, do you want to learn magic? Want to master martial arts? Seek spiritual cultivation? Cultivate mental energy? Don't worry. Under the "Three Souls and Seven Spirits" system developed 500 years ago by the theoretical master Dr. Tian Cai, the Imperial Comprehensive Academy has gathered mythical instructors from every tradition. Once you enroll, you can learn to wield a greatsword from Guan Yu, study blacksmithing with Lu Ban, master military strategy from Sun Bin, and discuss the Dao with Laozi. Three Souls: Main Soul, Life Soul, and Auxiliary Soul (awakenable), representing: True Heart, True Nature, and Instinct. Seven Spirits: Virtue Spirit, Wisdom Spirit, Physical Spirit, Vitality Spirit, Will Spirit, Speech Spirit, and Life Spirit (cultivable).
