In the distant future, humans have built a giant city "Star City" suspended in space as a beacon for interstellar civilization. However, a sudden energy crisis paralyzed the entire city and all power systems stopped functioning. During this disaster, the young female engineer Tong Li discovered that she had a unique ability-she could hear the "whispers" emanating from the core of the city. Those encrypted ancient codes were transmitting distress signals in the form of kinetic energy pulses.
While the city authorities and engineers were busy repairing the reactor, Tong Li discovered the shocking truth: the entire Star City was actually a dormant capsule for an ancient biological machine, and the so-called energy crisis was just a sign of its imminent awakening. What's even more frightening is that if this interstellar behemoth fully awakens, the three million residents in the city will become its first breakfast.
Tong Li must decipher these breathing codes within 72 hours and find a way to prevent the giant beast from awakening. However, she faces not only technical challenges, but also pursuit from the city's security department - they regard her as a dangerous person causing panic. With the help of a mysterious hacker, Tong Li gradually gets closer to the truth, but discovers that there is a greater conspiracy hidden behind this crisis: someone among the city's top officials already knows the truth about Star City, and plans to use the power of the beast to realize his ambitions.
As time passes, Tong Li must make a choice between saving the city and revealing the truth. Her decision will not only affect the lives of three million people, but also affect the future of the entire human civilization.
