**Timeline**: On the summer solstice of 2025, the near future is struck by the “Nine-Day Calamity.” Each day brings a disaster that grows exponentially more severe: a solar eclipse, virus, flood, war, endless night, extreme cold, lava, overlapping timelines, mass hallucination, and the reboot of the universe. The tenth day is the day civilization is reborn.
- **Myth and science intertwined**: The Mayan calendar, strange beasts from the Classic of Mountains and Seas, quantum physics, and genetic engineering all weave together. Anomalies in the moon's orbit, a bronze star map, Xirang particles, and the Primordial Chaos Egg all run through the story.
- **The core truth**: The calamity is actually a “calibration program” run by the cosmic womb. It is designed to select the seeds of civilization and prevent Chaos from awakening by resetting space and time.
#### **Main Storyline**
1. **The Calamity Begins**: Astrophysicist Lin Shen discovers an anomaly in the moon's orbit. A bronze fragment reveals an ancient star map, triggering a ten-day countdown.
2. **The Selection of Civilizations**: Each day's calamity tests a different aspect of human civilization. For example, the “Sixth Day of Cold” resets the evolutionary tree, while the “Seventh Day of Fire” reforges the axis of space and time.
3. **The Characters Awaken**: The main cast gradually discover their connections to ancient powers: Su Li's Jianmu roots, Tang Feng's Chi You bloodline, and Chen Mo's mechanical ascension.
4. **The Final Battle**: During the tenth day's “Birth of the Starry Firmament,” a hybrid civilization is born, and Earth rises into a “Bronze Cradle” linking the multiverse.
