After Rebirth: Dorm 806 Survived the Apocalypse by Stockpiling Supplies

Five college roommates in Dorm 806—Cheng Zhi, Chen Siyu, Xiao Feiran, Huang Yiyi, and Zheng Wan—awaken on the morning of October 10, 2023, realizing they have been reborn. In their previous life, they survived a catastrophic natural disaster triggered by Super Typhoon Ora, which led to societal collapse, starvation, and violence. All five perished tragically: Huang Yiyi drowned, Zheng Wan died from illness, Chen Siyu jumped from a building, Xiao Feiran was killed, and Cheng Zhi was beaten to death. Armed with memories of the future, they decide to use the two days before the typhoon makes landfall to prepare for the coming apocalypse.

Understanding that they will not survive long enough for government rescue, as they did previously, the group pools their limited funds to stockpile essential supplies. They purchase vast quantities of bottled water, long-shelf-life bread, canned food, vitamins, and medical supplies. During their preparations, they discover a supernatural phenomenon: an empty cabinet in their dorm mutates into an alternate dimension space. This space initially mirrors their dormitory but expands in size whenever books are fed into it. The space also contains land for farming, electricity, and water, providing a secure sanctuary isolated from the outside world.

The girls utilize keys that appear in the space, allowing them to instantaneously enter and exit the dimension regardless of their physical location. This ability proves crucial as they continue to acquire resources. They buy a heavy security door to reinforce their dorm, install privacy film on their windows, and purchase appliances such as refrigerators, freezers, and a generator, storing them within the space. Xiao Feiran, possessing practical skills inherited from her father, installs the door and builds enclosures for live chickens and rabbits they also acquire. Cheng Zhi takes a leadership role, coordinating the group's efforts and ensuring they remain focused on survival.

As Typhoon Ora makes landfall on October 12, the five girls barricade themselves in Dorm 806. The storm is severe, causing power and internet outages within days. With the internet gone, they can no longer access online information, but they have downloaded sufficient farming guides, medical manuals, and entertainment. The space accelerates plant growth, allowing vegetables to sprout within a day and enabling them to establish a sustainable food source. They also discover that the space has expanded significantly after they fed it books from the university library, transforming into a large, multi-room apartment with a garden.

During the typhoon, neighbors from adjacent dorms, desperate and hungry, knock on their door demanding food. The roommates refuse to share, recalling the betrayal and theft they suffered in their past life. Tensions rise as outsiders begin to loot nearby stores, signaling the breakdown of social order. The group remains cautious, monitoring the situation through binoculars and avoiding unnecessary contact. They focus on maintaining their supplies, caring for their livestock, and preparing for the long-term challenges of the apocalypse. The story concludes with the girls settled in their fortified dorm and expanded space, ready to face the harsh new world they now understand intimately.
