When the calamity struck, Chen Yu, a former warehouse worker, unexpectedly awakened an infinitely expandable storage space. It grew from a small storeroom into a mobile fortress. He teams up with Jiang Ye, a retired reconnaissance soldier, to stockpile supplies, build strongholds, and rescue survivors. But he discovers that the expanding space has drawn the attention of Qin Rui, a military task force leader, attracted the greed of He Zheng, a black-market boss, and holds secrets tied to an old laboratory in the hands of Lin Qi, a doctor. Chen Yu and Jiang Ye must survive in the narrow gap between human nature and the apocalypse, and upgrade the storage space into their final trump card for protecting their companions and rebuilding order.
