In the Primordial Era, there were giant spirits whose bodies were like stars, soaring through the universe. There were great beings of various races with strange blood, destroying the void and recreating the world. There were ancient Qi cultivators who traveled across the Milky Way to teach sentient beings. For unknown reasons, an era quietly ended, the Ten Thousand Realms were isolated, and the Primordial giants disappeared one after another. Many years later, the young man Nie Tian, through a drop of blood, returned to the Primordial Era.
