In this age of great strife, the young are born in the mortal world, in a land called the Desire Realm. The heart's longing gives rise to desire. This realm is the starting point of sentient life, and also the arena of reincarnation. All living beings are bound by the cycle of life and death, and their actions and desires determine where they will go in their next life. For countless millennia, untold lives have been pulled along by an invisible thread. Neither gold nor silver, neither silk nor fiber, its substance is hard to discern and its form impossible to find. It is like a cage, tightly binding the causes and effects of all things. From the dawn of time, people have been submerged in a sea of desire, trapped in the realms of reincarnation: hell, the hungry ghosts, and the beasts. They cannot escape. Born amid the torrents of desire in the Desire Realm, Zhu Shao seeks to break free of this cage. How will he enter the Ancient Immortal Era and compete with the divine prodigies, making his way toward the Heavenly Pillar, the origin of all things? Where does his path lie?
