An ‘useless' agriculture student who is actually a top-tier spiritual plant cultivator.

Jiang Luokui, a Nascent Soul stage cultivator from a spiritual world, finds herself reborn into the body of her university freshman self in a post-apocalyptic wasteland era. Having spent a century cultivating before her death, she returns to a time when humanity is struggling to survive amidst radiation, mutated flora, and scarce resources. The transition is jarring; she has lost her immense fortune and cultivation base, retaining only her memories and a D-rank ability that places her at the bottom of her agronomy cohort. Initially despondent and contemplating suicide, her perspective shifts when she discovers that spiritual energy still exists in this world and that her cultivation techniques remain functional. This revelation rekindles her will to live and provides a path to regain her former glory.

Her first priority is financial survival. In her previous life, she endured poverty, working three part-time jobs while studying agronomy, eventually dying during a dangerous gathering mission while trying to repay student loans. Determined to change her fate, she leverages her century of experience in spirit plant cultivation. She discovers that her natal spiritual plant, a radish-like entity named Bubu, has accompanied her rebirth. Although Bubu has reverted to a juvenile form, it retains the ability to produce a special essence that can stabilize mutated plants. Jiang Luokui begins by renting a small, remote plot of land with high radiation levels, which other students avoid. She spends a night purifying the soil through brute-force spiritual energy infusion, a process that nearly exhausts her but transforms the land into fertile ground.

With her land prepared, Jiang Luokui starts cultivating crops, beginning with scallions that she processes into spiritual scallion oil. The oil, which possesses mild mental-clearing properties, becomes an unexpected hit among students, providing her with her first significant income. Simultaneously, she offers her stabilization services to senior students, charging substantial fees for saving their mutated thesis crops. Her success attracts attention, particularly from Wang Meng, a fourth-year student whose corn she saves, and from Chen Pan, a civil engineering student who had previously orchestrated online harassment against her. Jiang Luokui turns the tables on Chen Pan, forcing him into a business arrangement that generates revenue for her betting pool scheme.

The narrative introduces underlying tensions regarding her past and future. Li Jueyan, a cousin of the top student Li Jue Ming, attempts to buy her out of the agronomy department, offering fifty thousand yuan for her to transfer. Jiang Luokui refuses, displaying a confidence that belies her low ability rank. Meanwhile, a mysterious figure from her past, Uncle Li, reappears in the city, revealing a familial connection to Jiang Luokui that suggests her origins are more complex than she remembered. This subplot hints at deeper secrets surrounding her adoption and the true nature of her rebirth.

As the semester progresses, Jiang Luokui faces academic challenges, including a difficult assignment to grow rice, a crop known for its high mutation rates and low yield in the wasteland. While her peers struggle, she approaches the task with the expertise of a master cultivator, intending to produce spiritual-grade rice. Her actions draw the scrutiny of Professor Qian, a renowned academic who teaches with an emphasis on survival in the harsh outside world. The professor’s warnings about rising mortality rates among researchers and the impending catastrophic disaster four years in the future weigh heavily on Jiang Luokui, who knows the truth of the coming collapse.

The story direction centers on Jiang Luokui’s dual struggle: rebuilding her cultivation base in a world with thin spiritual energy and navigating the social and political complexities of university life. She balances her studies with her entrepreneurial ventures, using her knowledge to create high-value spiritual products. Her goal is not merely to survive but to amass wealth and power sufficient to protect herself and her loved ones from the impending disaster. The narrative establishes a foundation for her rise from a despised D-rank student to a formidable figure in the agronomy field, setting the stage for future conflicts with rivals, the challenges of the wasteland, and the secrets of her past life.
