Before the founding of the nation, the Human Emperor, the founding patriarch, made a hundred-year pact with the three great sacred mountains of Kunlun, Changbai, and Shennongjia, relying on his extraordinary talent and supreme authority. Like a boundary marker on Kunlun’s snowy peak, like iron chains in the depths of the East Sea, the pact forcibly separated the ethereal immortal realm from the mortal world into two different realms. For a hundred years, immortals could not set foot on mortal soil, and mortals could not glimpse the path to cultivating immortality.
Once the pact was made, the three sacred mountains issued an edict: all their disciples had to return to their sects before October 1. Anyone who disobeyed would be severely punished according to sect rules, regardless of whether they lived or died. Yet the mortal world was full of distractions and splendor, and some immortals had lingered there for so long that its bright lights and pleasures had clouded their hearts. Bound by romantic attachments, they had long since cast their austere sects from their thoughts and insisted on remaining amid the mundane world.
The state established a powerful agency for the purpose: the Divine Investigation Bureau, also known as Bureau 749. It keenly sensed the movements of these rogue immortals. The bureau deployed all its elite forces, laying a vast net across the provinces and prefectures. Anyone found to have violated the hundred-year pact would be arrested without exception or leniency...
Only thirty-three years remain until the hundred-year pact expires. On that day, the immortal sects will be free to enter the mortal world, and the barriers between the Three Realms will shatter. Humans, immortals, demons, and ghosts will once again fight over the space they need to survive.
