After Becoming the Youngest Junior Sister of an Immortal Sect the Cultivation World Went Crazy for Me

Ning Yue, a modern individual with extensive knowledge of cultivation novels, awakens in a desolate landscape after what she believes was her death. She discovers her body has been rejuvenated to that of a twelve or thirteen-year-old child, though a flame-shaped birthmark confirms her identity. The environment is immediately hostile, featuring flying carriages and cultivators who defy conventional physics. A wealthy, malicious young man named San Pang from the Fusang Sect abducts her, intending to humiliate her by tying her to the back of his carriage. Before she can suffer further, Shi Yinghan, a senior disciple of the Fusang Sect, intervenes. He rescues Ning Yue, displaying exceptional skill and kindness, and offers to teach her basic cultivation techniques in preparation for the upcoming disciple recruitment ceremony.

Ning Yue quickly deduces she has transmigrated into a cultivation world. Recognizing the danger of her weak physical state, she accepts Shi Yinghan's offer and begins training. During her meditation, she unexpectedly enters a consciousness space filled with a sea of flowers and a sentient plant companion named Xiaohua. This realm contains a library with cultivation manuals, including one titled "Three Days to Foundation Establishment." Xiaohua warns Ning Yue of a grim future where she is killed by a figure in black robes, urging her to cultivate immediately to survive. Ning Yue utilizes the time-dilated environment of her consciousness space, spending fifty hours cultivating in what feels like ten hours in the real world. She rapidly advances from a mortal to the late Foundation Establishment stage, a feat that causes massive spiritual energy fluctuations detected by the Fusang Sect elders.

Before the recruitment, Ning Yue encounters Qi Xucheng, the second-ranked individual on the Heavenly Ranking and the son of the Netherworld Sect Master. Their interaction is tense; Qi Xucheng attempts to assert dominance, but Ning Yue, protected by Xiaohua, deflects his attacks effortlessly. This display of hidden strength intrigues Qi Xucheng, who insists on sharing her room to investigate her origins. Meanwhile, four Fusang Sect elders, driven by the spiritual fluctuations, spy on Ning Yue and recognize her as a rare genius. They bestow upon her a direct disciple jade token, guaranteeing her entry into the sect regardless of the trial results.

At the recruitment venue, Ning Yue witnesses Jiang Yishen, a quiet boy in white, being bullied by arrogant teenagers from a prominent family. She intervenes, using her newfound power to repel them. When the bullies reveal they have purchased outer disciple tokens, Ning Yue produces the direct disciple jade token, shocking the managing elder and reversing their fortunes. The bullies are expelled, and Ning Yue proceeds to the trials with Jiang Yishen. In the first trial, a jungle secret realm, Ning Yue demonstrates her versatility by creating shields and using fire attacks to clear a path, breaking the sect's record for completion time. Jiang Yishen, impressed by her talent, chooses the alchemy path while Ning Yue selects sword cultivation.

Inside the sword cultivation trial, Ning Yue faces a mysterious girl in yellow who has been trapped for over a hundred years. The trial requires Ning Yue to land a single blow on the girl or damage her clothing. Despite the girl's superior speed and experience, Ning Yue persists through repeated deaths and respawns. Her determination and rapid adaptation eventually allow her to catch the girl off guard, tearing a piece of her clothing. This success completes the trial, marking Ning Yue's official entry into the Fusang Sect as a direct disciple. Her journey from a helpless newcomer to a recognized genius sets the stage for her future conflicts with demonic races and internal sect politics, while the threat of the black-robed figure looms in the background.
