Yang Xi is a fourteen-year-old servant in the Cheng family estate in Xianlai Town, possessing spiritual roots but lacking a sect, mentor, or family. Sold into servitude at age six for two copper coins because her eyes resembled a Persian cat, she endured a childhood marked by extreme hardship, including famine, near-cannibalism, and attempted sacrifice by a hunchbacked man. These traumatic events manifested as heart demons that block her cultivation progress. Despite her lowly status and illiteracy, Yang Xi harbors a singular, ambitious goal: to build a cultivation foundation, a milestone that separates mortals from immortals and grants longevity and freedom from worldly laws. For three years, she has failed sixty-four times to break through the second layer of Qi training, each failure caused by a resurgence of her past traumas. Her only guidance comes from a dying old Taoist who painted a metaphorical picture of the foundation-building path, tempting her with the promise of transcendence.
The core conflict arises from Yang Xi’s desperate need to overcome her heart demons and advance in cultivation without resources or protection. The Cheng family, her employers, is a powerful local clan with a single foundation-building ancestor, Cheng Sicheng, who secured their dominance in the region. While the family’s young masters and miss prepare to travel to Kunlun Mountain, the premier sword sect, to apprentice as inner disciples, they announce a dangerous selection process for sword servants. The position offers a twenty-tael silver settlement fee and a chance to enter Kunlun, but the selection is lethal, with many candidates expected to die. Yang Xi, recognizing this as her only opportunity to escape her stagnant cultivation and servitude, signs a life-and-death contract, selling her body again for a second time to secure her place among the servants accompanying the Cheng children.
A key turning point occurs when Yang Xi overhears a conversation between the Seventh Young Master and the Fourteenth Miss regarding their trip to Kunlun. She is particularly struck by the Young Master’s description of sword cultivators as those who "slay gods and demons and eliminate inner demons." Interpreting this literally and pragmatically, she believes that enduring the beatings and scoldings of a harsh master at Kunlun might be the key to conquering her own heart demons. This realization shifts her motivation from mere survival to a calculated gamble on her future. She views the brutal training not as punishment but as a therapeutic tool to purge the psychological barriers that have stalled her progress for years.
Yang Xi’s journey is characterized by her stubborn resilience and pragmatic approach to a world that has repeatedly exploited her. Unlike the privileged Cheng children who view Kunlun as a path to family honor, Yang Xi sees it as a means to personal liberation. Her physical appearance—delicate, pale hands marred by self-inflicted cuts from cultivation attempts—contrasts with her inner ferocity. She documents her failures in a rough notebook, analyzing each setback with cold logic, such as noting that the healing speed from breaking illusions is surprisingly high. This methodical yet desperate approach highlights her isolation; she has no one to guide her, no sect to support her, and no safety net. Her decision to join the Kunlun expedition is a calculated risk, betting her life against the possibility of breaking through her cultivation bottleneck. The story sets the stage for Yang Xi to enter the dangerous world of high-level cultivation sects, where she must navigate political intrigue, lethal trials, and her own psychological demons to achieve her goal of foundation building.
The narrative establishes a stark contrast between the opulent, sheltered lives of the Cheng family’s children and the brutal, survivalist existence of Yang Xi. While the young masters and misses discuss the prestige of Kunlun and the dynamics of family hierarchy, Yang Xi is focused on the mechanical aspects of survival and advancement. Her heart demons are not abstract spiritual obstacles but vivid, visceral memories of starvation, violence, and betrayal. The story suggests that her path to power will require her to confront these memories directly, possibly through the very "sword cultivation" that promises to slay demons. As she prepares to leave the relative safety of the Cheng estate, Yang Xi steps into a larger, more dangerous world, driven by a hunger that is both physical and spiritual. Her lack of education and social standing becomes irrelevant in the face of her singular determination, positioning her as an underdog in a cultivation world dominated by lineage and resource accumulation.
The introduction of the Kunlun Mountain sect serves as the next major arena for conflict. As a sword servant, Yang Xi occupies a subordinate role, yet her ambition places her on a collision course with the sect’s rigorous and likely brutal training methods. The story hints that her unique background, forged in suffering, may provide her with a resilience that privileged cultivators lack. The "heart demon" motif remains central, suggesting that her internal battles are as significant as any external threats she will face. Her previous failures indicate that spiritual advancement is inextricably linked to psychological healing, a theme that will likely drive the narrative forward as she seeks to transform her trauma into power.
