Story summary
- **Unexpected Discovery**: Quantum physicist Chu Wentian discovered abnormal data in microscopic particles during the experiment, and accidentally established quantum entanglement communication with the "observer" of the four-dimensional civilization.
- **Dimensional truth**: The Observer civilization reveals that they are trapped in the high-dimensional space inside the atomic nucleus and are experiencing dimensional fall, and human experiments have accelerated this process.
- **Civilization Game**: The attitudes of various countries on the earth towards four-dimensional civilization are divided. Military representative Lei Yue advocates weaponized research, triggering a struggle between the two factions "Tinder" and "Ark".
- **Dimensional Invasion**: Four-dimensional fragments fell into the earth, causing local physical laws to be disrupted. Chu Wentian discovered that this was a planned dimensional immigration by the observer civilization.
The ultimate choice: Humanity faces the choice of integrating with four-dimensional civilization or resisting. Chu Wentian must solve the dimensional equation left by Yang Dong to save the two civilizations.
