Young Chu Chen accidentally falls while collecting herbs and obtains a golden-winged roc's incarnation. This allows him to enter a poison-filled immortal mountain, the site of an ancient battle between immortals and demons. The mountain contains countless corpses, treasures, spiritual herbs, and immortal grasses of fallen gods and demons. As the golden-winged roc grows, it can fly higher, obtaining better treasures and herbs. This immortal mountain, where countless gods and demons perished, becomes Chu Chen's "super treasure trove" on his path to becoming the Nine Yang Emperor Zun.
