Lu Shaoan is an orphan without spiritual roots who is sent to the Myriad Beasts Sect to work as a servant. By chance, he unearths the Kunlun Bronze Mirror, a treasure capable of purifying all things and tempering bloodlines. After malicious people make things difficult for him and transfer him to the dangerous Spirit Beast Mountain, he is fortunate to receive Li Sheng's protection and obtain basic cultivation techniques. Unable to cultivate through conventional methods because he lacks spiritual roots, Lu Shaoan uses the bronze mirror to purify spirit beast meat and forcibly break through his meridians, embarking on a unique path of body tempering before body cultivation. Gu Ping covets his spirit beasts and causes Li Sheng's death, prompting Lu Shaoan to swear revenge. Using the bronze mirror, he cultivates large numbers of ancestral spirit beasts. Shen Yueru, a Foundation Establishment cultivator, takes him as her first disciple. He also forms a contract with Xiao Tu, a Heaven-Swallowing Dog possessing Taotie bloodline. In a secret realm, he personally slays his enemies and continuously breaks through his limits with the help of the bronze mirror and the devouring power of Taotie.
