Lin Su is the daughter of a wealthy family that operates a nationwide chain of supermarkets. She lives a comfortable life in An City, managing the company's operations while residing in a high-end villa community. Her routine is shattered on a scorching August morning when she witnesses strange, floating text comments appearing in her vision. These comments identify her as a cannon fodder character in a novel and reveal that a natural disaster apocalypse is imminent. The comments also name Cheng Jiajia, a woman buying bulk supplies at Lin Su's supermarket, as the female lead who will survive and take over Lin Su's resources.
Terrified by the revelation, Lin Su investigates and discovers that Cheng Jiajia is indeed a tenant in her residential community, renovating her apartment into a fortress. Lin Su realizes she is not the protagonist and that the world is governed by narrative logic that favors Cheng Jiajia. However, Lin Su also discovers a unique ability: a small, glowing dot on her wrist that grants her access to a dimensional storage space. This space can preserve items indefinitely in a vacuum-like state, making it an invaluable asset for survival. Unlike Cheng Jiajia, who relies on precognitive dreams and a similar space to loot supplies, Lin Su has the advantage of her family's extensive supply chain and logistical network.
Lin Su immediately begins a massive stockpiling operation. She uses her family's supermarkets to gather vast quantities of food, water, clothing, and daily necessities. She also leverages her family's connections to secure coal, weapons, and medical supplies. Her father, initially skeptical, is convinced when Lin Su demonstrates her space ability. The family works together to reinforce their villa with triple-layered walls, insulated windows, and electrified perimeters to withstand extreme weather events. Lin Su also ensures her neighbors, including her close friend Wen Shiyun and the He family, are prepared, distributing solar generators and organizing community renovations to avoid standing out as the only fortified house.
As the apocalypse approaches, tensions rise. Cheng Jiajia continues her preparations, unaware that Lin Su knows her secrets. Lin Su monitors Cheng Jiajia's movements and learns that she is hoarding supplies in a secret storage room in the community's underground garage, using her own space to transport goods. Lin Su also encounters Zhou Mi, a former classmate and rival, who is connected to the wealthy families that will be affected by the coming disaster.
The situation escalates when a private jet carrying chemicals explodes at An City Airport due to the extreme heat. The explosion causes panic, injuries, and significant damage, including the destruction of another private jet owned by the Zhou family. Lin Su, who was on a different plane, survives and returns home, but the incident highlights the increasing instability caused by the extreme weather. The news reports of heat-related disasters, power grid failures, and social unrest signal that the apocalypse is closer than expected. Lin Su continues her preparations, knowing that the world is on the brink of collapse and that her survival depends on the resources she has gathered and the alliances she has built.
