**Core premise**:
In 2028, an asteroid impact triggers a global volcanic winter. The selfish businessman **Wang Shengda** dies miserably in the frozen hell, only to be reborn three months before doomsday with a **120-cubic-meter evolvable pocket dimension**.
He sells off his Bitcoin, mortgages his company, and takes out loan-shark debts to turn an air-raid shelter into a **doomsday fortress**. But while stockpiling supplies, he discovers that
- The voice recorder belonging to his **ex-girlfriend Lin Xiaowei** contains interdimensional coordinates
- The blueprints secretly kept by a construction foreman are marked with **alien writing**
- Every time he stockpiles supplies, it triggers a mysterious **earthquake warning**
When the endless night falls, he thinks he can keep to himself with the help of his pocket dimension, but instead he encounters:
- The **Quantum Council’s** dimensional-reduction trial: human civilization turns out to be a **failed exhibit** created by higher life forms
- The **clone army’s** hunt: every version of “himself” from a parallel universe has a different death to his name
- The tyranny of the **Photosynthetic Era**: Lin Xiaowei’s clone uses humanity’s painful memories to cultivate **cosmic fuel**
Wang Shengda calculates calories using frozen corpses in icebound New York, hides weapons inside Van Gogh’s "The Starry Night", and uses Bitcoin mining rigs to tunnel through a quantum prison. When he discovers that his so-called rebirth is nothing more than an experiment by a higher civilization
