Myriad Realms Travel Agency The True Daughter Ascends with the Nation

He Mu is a high school student with a rebellious exterior, characterized by her wine-red short hair and a history of skipping classes and fighting. Despite her troubled reputation, she shares a deep bond with her grandmother, Zhao Meimei, who raised her after her parents, He Fendou and Chen Jing, abandoned her care. He Mu’s parents are actually servants for the wealthy Zhang family, where they secretly work while harboring resentment toward He Mu, whom they view as a mistake due to a childhood baby swap that revealed He Mu is not their biological daughter. The family’s true biological child, Zhang Nian, is being raised as the cherished daughter of the Zhangs. He Mu’s life unravels when her uncle, He Xiaosa, falsely accuses her of causing her grandmother’s heart attack through neglect. While He Mu kneels in prayer outside the operating room, a mechanical voice binds a Dimensional Travel System to her. The system offers a trial task: recruit three tourists for a one-day tour to a primitive society 1.7 million years ago. Success grants thirty days of lifespan to any designated individual and a one hundred thousand yuan bonus; failure results in a ten-year deduction from He Mu’s own lifespan.

Desperate to save her grandmother, He Mu recruits three classmates: her loyal best friend Su Miaomiao, the school bully Lu Shiyan, and Su Miaomiao’s wealthy brother Su Mu. Lu Shiyan initially approaches her with hostility but signs the contract after receiving an envelope of cash from He Mu, which she refuses to keep as payment. Su Mu joins reluctantly to protect his sister but is intrigued by the legal contract and the potential for commercializing time travel. The group enters a tunnel in He Mu’s uncle’s minibus, which transports them through a blinding light to the era of Yuanmou Man. Upon arrival, they discover the environment is rich in Spiritual Qi, which benefits their health but requires caution. He Mu quickly establishes herself as a capable guide, saving a Yuanmou Man child from a vulture and teaching the tribe how to create fire through friction. This act triggers a hidden mission, rewarding her with a Fire Spiritual Root, though its effects are delayed for years. The group participates in a hunt, where Lu Shiyan injures his leg protecting He Mu from a wild boar, and Su Mu uses an electronic beast repeller to secure their safety.

After spending twenty-four hours in the primitive society, the group returns to the present, having experienced a full day in merely one minute. He Mu rushes to the hospital morgue to use the system’s reward. However, the system reveals a critical discrepancy: the thirty-day lifespan reward cannot revive Zhao Meimei because she is not He Mu’s biological grandmother. The system detects that He Mu’s true blood relative is someone else, implying the baby swap story is only partially true or that her biological lineage is connected to the Zhang family. Despite this revelation, He Mu insists on using the reward on Zhao Meimei, whose body is still fresh. As she confronts her abusive parents in the morgue, Chen Jing attempts to strike her, but He Mu defends herself. Meanwhile, Su Mu visits the hospital dean, presenting blood samples and video evidence from the primitive era, sparking his interest in the scientific implications of He Mu’s system. The story concludes with He Mu facing the harsh reality of her non-biological ties while Su Mu begins to investigate her mysterious connection to the powerful Zhang family, setting the stage for future conflicts involving her true identity and the system’s deeper secrets.
