Young Qin Yun was originally an apprentice at a pharmacy shop in a border town. He was gifted in pharmacology but his spiritual power was stagnant and his practice was hopeless. Overnight, the family was massacred by mysterious men in black. Before his death, his father entrusted him with half an ancient jade and a mysterious jade slip to guide him to the Xuantian Sect, the great sect of immortals.
On the verge of death, Qin Yun was rescued by the reclusive master "Yao Lao". Yao Lao understood the shocking secret in his body - Qin Yun possesses a "chaos body" that is rare to see in ten thousand years, but his spiritual root talent is locked by a nine-layer mysterious seal! Yao Lao unlocked part of the seal for him and taught him the supreme alchemy code "Xuantian Pharmacopoeia". Qin Yun's cultivation improved rapidly, and his talent in alchemy shocked the world.
Following his father's orders and entering the Xuantian Sect, Qin Yun started out as an outer disciple and emerged in a crisis-ridden environment. He met Shi Potian, the son of a bold Orion, and Liu Qingyao, the daughter of a smart wealthy businessman. The three of them formed a deep friendship. However, as Qin Yun's cultivation level improved, the seal in his body loosened, which attracted a crazy pursuit from the mastermind behind it - the demon giant Nether Palace. Yao Lao's true identity then surfaced, and he was actually the former head of the Xuantian Sect! In order to protect Qin Yun, Yao Lao's remnant soul dissipated, leaving behind a shocking last word: Qin Yun is the "chosen son" prophesied to resolve the catastrophe of chaos for thousands of years, and the chaotic body in his body is the only hope!
The master of Netherworld Palace plots to open the gate of chaos and seize the original power. To this end, he does not hesitate to start a sect war. Qin Yun bears the responsibility of blood feud and salvation. He holds half an ancient jade relic from his father and learns that he needs to collect five original jade pendants scattered across Kyushu in order to fully awaken the Chaos Body and compete with the Nether Palace. He bid farewell to Xuantian Sect, rescued and got acquainted with Xue Linglong, the tribal saint who guarded the "Water Spirit Pendant" in the northern ice field, and jointly fought against the minions of the Netherworld Palace.
