Yu Zhuji is the true daughter of the Qingxuan Sect who was mistakenly switched at birth, and she suffered endless cold treatment after returning to her clan. Ning Shengnian, the senior martial brother she adored since childhood, broke off his engagement with her for the fake daughter Yu Xueer, and her parents also urged her to accommodate them. In her desperate plight, the gentle companionship of the second senior martial brother, Shang Fuyan, became her only redemption, making her deeply entangled in love. However, on the eve of their betrothal, she accidentally learned that Shang Fuyan's ten years of partiality were all an act, and his approaching her was solely to keep Yu Xueer safe. With her heart turned to ashes, Yu Zhuji bound a system, traded a fake death by falling off a cliff for a new life, and retreated into the peach blossom boundary to start a completely new life. She underwent a nirvana transformation and achieved great cultivation; the two people who had once failed her henceforth became obsessed and paranoid, scouring heaven and earth through the rest of their lives, deeply trapped in endless regret.
