Chu Xuan, once the peak cultivator Venerable Xuanxiao, was reborn through a self-detonation of his cultivation and returned as an illegitimate son of the Chu family of Nanling. In this world, countless races vie for supremacy, immortal opportunities lie hidden, sects carve up the land, and imperial dynasties hold power. He returns with a thousand years of accumulated knowledge, only to find himself trapped in a plot: his legitimate elder brother bullies him, and his dantian has been crippled. Family rivalries, secrets hidden in the medicinal garden, and his mother's final letter conceal the truth. A ghost in the forbidden grounds passes on a cultivation technique, and a body-tempering art sets him on the path of cultivation. His breakthrough to Qi Condensation creates strange phenomena, drawing the elders' scrutiny as he uncovers the Bloodfiend Cult's conspiracy. He seizes a ring and kills his attacker, then fakes his death to escape. During a trial, he saves Lu Qingyao and obtains half of an ancient mirror. With the Ice Soul protecting him, he forms an alliance with Li Wufeng and ventures into the Nanling swamps. Cultivating anew in this life, he vows to break free of fate's shackles and ascend to immortality against all odds.
