At the Start of the Apocalypse, I Easily Won Thanks to a Sign-In System

Chen Xi is an intern at the Quick-Transmigration Bureau, tasked with stabilizing small worlds that have deviated from their original storylines. Her assignment is to enter a collapsing apocalypse world derived from a novel, where the male and female leads must reach a happy ending. However, due to a system glitch, she is placed in Hard Mode without prior warning. Upon arrival, she discovers she is in the body of a junior university student named Chen Xi, living in a small apartment in S City. The apocalypse is set to strike within hours, transforming humanity into zombies. Realizing the gravity of the situation, she rushes to stockpile food and water before the outbreak occurs at midnight.

After surviving the initial chaos by eliminating a zombie at her door, Chen Xi learns that her mission cannot be aborted. To aid her survival, the system provides a daily check-in reward mechanism. Over the following weeks, she accumulates resources, weapons, and items that enhance her physical abilities. She clears her apartment building of zombies and forms an alliance with Aunt Xu, an elderly neighbor with martial arts training. Chen Xi also discovers crystal cores, which serve as currency in this new world and can be used to upgrade her system. Her primary goal shifts from merely completing the mission to establishing a secure base of operations.

A significant turning point occurs when Chen Xi receives a portable space and later a Hotel Management System. She establishes the Dawnlight Hotel on the outskirts of S City, a safe haven protected by an impenetrable shield. The hotel offers electricity, hot water, food, and lodging in exchange for crystal cores. This attracts survivors, including Jiang Chengyu and his companions, who are amazed by the pre-apocalypse comforts. The hotel quickly becomes a hub for survivors, allowing Chen Xi to accumulate wealth and upgrade the facility multiple times. She hires Lin Man, a survivor who fled abuse at a base, to manage daily operations, freeing Chen Xi to focus on expansion and zombie hunting.

Meanwhile, the novel's male lead, Huo Yan, is rescued by Chen Xi after being injured and left for dead by his teammate Deng Tong. Huo Yan, who has been reborn with memories of a previous life, recognizes Chen Xi's potential importance. He stays at the hotel with his group, including Aunt Xu's son, Xiao Yang. Huo Yan's presence introduces political dynamics, as he seeks to find the female lead, Lin Jingxue, whose spatial spring is crucial for developing a vaccine. Deng Tong, the antagonist, is also active in the world, having colluded with the Zombie King in his past life.

Chen Xi continues to upgrade her hotel, adding a restaurant, weapons hall, and more rooms. She sells special items like universal bandages that can heal zombie bites, further cementing the hotel's reputation as a sanctuary. The female lead, Lin Jingxue, eventually arrives at the hotel, bringing the main characters together under Chen Xi's roof. Despite the system's insistence on her mission, Chen Xi prioritizes her own safety and comfort, running her hotel business while the protagonists navigate their fates. The story follows her adaptation to the apocalypse, her rise as a powerful figure through resource accumulation, and her interactions with the key characters of the original novel.
