Modern university student Li Xuan's soul travels back in time and inhabits Li Daotong, a Kangjin Dragon who was demoted to a “fallen dragon” during the Investiture of the Gods war between the immortals.
Heaven and earth are unkind, treating all things as straw dogs. The sages are unkind, treating the people as straw dogs. Since Pangu first split heaven and earth, Heaven, Earth, and Humanity have stood as the three realms, and all living beings were born equal. Through ages of primitive farming and the taming of beasts, our human ancestors, guided by the Three Sovereigns, the Five Emperors, and generations of sages, learned to fish and hunt, established laws and rites, taught the people to farm, tested herbs with their own bodies, tasted poisons to make medicine, observed the world, and created written characters. At last, with the wisdom of countless ancestors and the lives of billions of beings, our people founded the nation of Zhongshang. Its rule of law was taking shape, its rites and music were taking form, its civilization was dawning, and the realm was beginning to prosper. But the Heavenly Dao was unkind. Fearing that our people would rise and prosper, it sent monsters to ravage our nation, sowed discord among the peoples, incited war, and repeatedly brought down natural disasters, leaving the people in misery. King Zhou, the Human Emperor, was driven to burn himself to death at the Star-Plucking Tower in Chaoge. The Human Emperor's throne stood empty, and the destiny of humanity scattered throughout heaven and earth. At last, our people's fate was all but destroyed. Worse still, our human destiny was cut off and our supreme ruler extinguished. From then on, our people had no more “Human Emperor.” The puppet emperors who followed were demoted to the title of Son and became “Sons of Heaven.” After that, the realm was torn apart, law and reason vanished, and people were no more than ants, their lives as cheap as weeds. What a joke: what are heaven and earth, what are sages? Though I, Li Xuan, am but an ant, I have the will to split open the heavens. If immortals stand in my way, I'll slay immortals; if gods stand in my way, I'll kill gods. I swear to restore my people's glory!
