Gu Yue is summoned to a remote hillside in Xiaba Village by Song Chu, the local and notorious village bully. She threatens to expose the secret of his crippled grandfather unless he agrees to marry her into the family. Before Gu Yue can give a definitive answer, a sudden, roaring mudslide triggered by weeks of rain buries them both under tons of mud, rocks, and debris. Song Chu’s soul dies in the apocalypse and immediately transmigrates into the body of the buried bully just as she suffocates. Crawling out of the wet, heavy mud, the new Song Chu quickly assesses her situation. Her complete research laboratory, her greatest treasure from her past life working at the base’s institute, has been shattered by the traumatic soul transfer. One half, a specialized library full of rare scientific volumes, exists peacefully in her own mental space. The other half, containing crucial experimental equipment and valuable research materials, is inexplicably lodged in the mind of the man lying half-dead beside her. Compelled by the absolute necessity to reclaim her full power and resources for survival, Song Chu pulls Gu Yue from the suffocating mud. Using the original body’s extraordinary physical strength, she effortlessly throws him over her back and sprints down the mountain to the village clinic. The terrified village doctor treats Gu Yue’s fever and serious leg injury, ordering him to strictly rest on the ground for at least half a month without walking.Gu Yue is immediately struck by the profound change in his savior’s eyes. The infatuation and threatening obsession are completely gone, replaced by a sharp, rational, and very detached demeanor. Song Chu helps him back to the educated youth point where they can talk in complete private. She wastes no time. She directly asks him, “Did something extra appear in your mind?” Gu Yue’s suspicions are confirmed. The strange laboratory full of unknown, futuristic machinery is not a mere hallucination from his injury. Song Chu explains the true origin of the space without hesitation. It is her laboratory, a complete research institute, split in two when her foreign soul crossed the dimensional void during the mudslide plunge. She needs his complete cooperation to recover the other half. Gu Yue, highly intelligent and intensely curious about the alien high-tech space, agrees to a temporary but firm partnership. Since his leg is lame and he cannot cook in the communal educated youth kitchen, he directly proposes a transaction. Song Chu will bring him all his meals for the next ten days. He will pay her with money and grain coupons to create a fair exchange. In return, he will allow her full, open access to the space residing in his mind. Gu Yue reveals he can also see the vast library in Song Chu’s half of the space and is extremely interested in reading the specialized books. Song Chu permits this, firmly stating this arrangement is a loan that must be returned to her eventually. Gu Yue accepts the terms, strongly preferring the current cold, rational Song Chu to the previous threatening and infatuated one. They form a solid pact sealed by necessity and mutual gain.Song Chu returns to her new family’s courtyard. Her mother, Tang Feng, is the village’s undisputed Queen of Fights and the family matriarch. Seeing her precious daughter covered in mud, she immediately suspects Gu Yue is to blame and even offers to frame him as a hooligan to force him into marrying her. Song Chu firmly declines, explaining she is no longer interested in him in that way. She tells her mother a well-crafted story about wanting to make Gu Yue fall in love with her and then dumping him to get revenge for his previous cold rejection. Tang Feng is delighted by her daughter’s cunning plan. Later, at the family dinner, Song Chu’s scheming eldest sister-in-law, Luo Qiuju, tries to publicly humiliate her for laziness and faking her studies. Song Chu ruthlessly retaliates by exposing Luo’s secret habit of stealing family grain. She then drops a major bombshell: she is not going to take the high school entrance exam anymore. The entire family is shocked. Song Chu ignores their disbelief and their sighs. She makes a silent vow to the spirit of the original owner to take care of this lively family and restore their damaged name in the village. Her true long-term plan stems directly from her past life experiences. Before the apocalypse, she was a brilliant PhD in biology. She perfectly remembers the historical events of this parallel 1970s era. It is 1975. The national college entrance examination is destined to be reinstated very soon. Gu Yue shares this same suspicion, and they often discuss politics, literature, and future opportunities during her daily meal deliveries. Gu Yue recommends high school textbooks for her to study, impressed by her sharp mind. Song Chu agrees, seeing the upcoming exam as her main ticket to a new and meaningful life. The provided text ends with Song Chu solidifying her complex role in her immediate family and solidifying her secret, knowledge-driven partnership with the intelligent Gu Yue. She begins to navigate the complex village politics, manages her super strength and her half of the lab, and carefully watches over the space in Gu Yue’s mind. The ultimate goal remains perfectly clear: she must complete her recovery schedule, patiently retrieve the other half of the laboratory from Gu Yue, and lay a strong foundation for her future scientific rise in this new, primitive world.
