Starting in The Wandering Earth by Signing In for Survival Supplies

Chu Xuan, a former corporate drone from the modern era, transmigrates into the body of a university student in the world of The Wandering Earth. He awakens in Underground City No. 3 in January 2074, merely one year before the catastrophic Jupiter Crisis. The original owner died from overwork, leaving Chu Xuan with a fragile health status and a precarious position as a botany major with minors in astrophysics and microbiology. Upon arriving in this new reality, Chu Xuan discovers he possesses a Sign-In System that grants him daily resources, primarily food, with a one percent chance of yielding special items such as genetic enhancement solutions and portable storage space. This system becomes his primary tool for survival in a world where synthetic food is the norm and fresh ingredients are luxuries reserved for the elite or distributed sparingly on holidays.

Chu Xuan’s immediate goal is to survive the impending planetary disaster, but he also seeks to improve his standing in this rigid society. He leverages his academic background to write a thesis titled "On the Hazard Analysis of the Gravitational Slingshot After Earth’s Trajectory Changes." The paper argues that Earth’s previous orbit changes near the asteroid belt have created a non-zero probability of a Jupiter gravity anomaly, potentially leading to the failure of planetary engines. He proposes countermeasures, including the pre-positioning of ignition devices, to mitigate this risk. Simultaneously, he uses the Sign-In System to obtain high-quality food and genetic enhancements, steadily improving his physical condition and cognitive abilities. He discovers that interacting with his neighbor, Han Duoduo, significantly increases his luck, allowing him to trigger bonus rewards more frequently. This realization leads him to cultivate a close relationship with Han Duoduo and her family, including her brother Liu Qi and grandfather Han Zi’ang, sharing rare foods like apples, beef, and hotpot to maintain this beneficial connection.

The narrative follows Chu Xuan as he balances his academic responsibilities with his secret preparations. He navigates the strict social hierarchy of the underground city, where preferential status grants certain immunities and benefits based on parental contributions to the Wandering Earth Project. His parents, both high-ranking officials and engineers, died in the line of duty, leaving him with a modest apartment and social standing but no active protection. Chu Xuan attends classes, completes his internship at the N3 Experimental Base, and gradually builds a network of acquaintances. He interacts with Liu Qi, who is rebellious and sensitive about his father Liu Peiqiang, and Han Zi’ang, a veteran rescue team member. Through these interactions, Chu Xuan gains insight into the social dynamics and potential allies he might need as the crisis approaches.

A key turning point occurs when Chu Xuan submits his thesis to his advisor, Professor He Shuli. The professor is initially skeptical but becomes intrigued by the data and mathematical models presented in the paper. Despite the low probability of the predicted disaster, the potential consequences are so severe that the United Government cannot ignore the possibility. Chu Xuan’s work begins to attract attention within academic and governmental circles, positioning him as a potential contributor to the crisis management efforts. As the story progresses, Chu Xuan continues to sign in, accumulating resources and enhancing his body, while also preparing for the possibility of being called upon to assist in preventing the Jupiter Crisis. His dual focus on personal survival and contributing to the greater good sets the stage for his involvement in the major events that will test humanity’s resolve.

The story direction indicates that Chu Xuan will use his foreknowledge and system-gained advantages to play a more active role in the unfolding disaster. He aims to warn the authorities and potentially influence the outcome of the Jupiter Crisis, which is depicted as a moment of extreme peril for Earth. The narrative explores themes of survival, social stratification, and the human spirit in the face of existential threats. Chu Xuan’s journey from an ordinary intern to a key figure in the resistance against cosmic disaster forms the core of the plot. His relationships with Han Duoduo, Liu Qi, and Han Zi’ang provide emotional anchors and support systems as he navigates the challenges of this harsh new world. The story culminates in the lead-up to the Jupiter Crisis, where Chu Xuan’s preparations and insights will be put to the ultimate test.
