Shen Yanzhou, an outer disciple of the Qixia Sect, has a mixed and impure spiritual root and is often mocked as a useless cultivator. Yet he neither complains nor loses heart. While working in the spiritual fields, he comprehends a cultivation method called 'Plowing Clouds, Planting the Moon.' Su Wanqing, an attendant in charge of the medicinal herb gardens, notices his delicate and thoughtful nature and invites him to investigate the imbalance in the spiritual clouds over the fields. As the sect's trial approaches, Gu Lingxiao, an inner disciple and prodigy, openly questions his abilities. Through diligence, Shen Yanzhou makes up for his shortcomings. During the trial, he guides the cloud energy to nourish the spiritual fields and saves a hundred acres of spiritual plants. In the end, with an ordinary spiritual root, he comprehends an extraordinary path, proving that diligent cultivation and a kind heart can also lead to immortality.
