The protagonist Lin Xiao is the guardian of the ruins of chaos. His parents were killed by Xuantianmen traitors because he refused to hand over the keys to the ruins. He has practiced hard in the ruins for more than ten years and learned the anti-routine practice method (using himself as a furnace to reversely absorb spiritual energy and refine the chaos energy). After coming out of the mountain, he met a betrayed Fa Xiao and killed his enemies. He met the gentle maid Su Qing and got involved in the sect fight. He received the guidance of a hidden master (the remnant soul of the Relic Immortal Lord) and unexpectedly obtained the ancient magic weapon "Proud Sword", which enabled him to practice quickly. When establishing the Xiaoyun Sect and expanding its territory, his beloved Su Qing sacrificed his life to save him and fell into self-doubt. Later, he was comforted by his brother and the miracle doctor Bai Ruoxue and regained his confidence. In the end, the mastermind behind the scenes (the head of the Xuantian Sect) was revealed, he avenged his parents, became an immortal, and protected the world.
