A gifted and beautiful girl, Tong, who suffers from a special terminal illness: as long as her mind stops thinking, the metabolism in her body will rapidly increase, and she will die from aging in a few hours. Every day, Tong buries herself in hundreds of strange puzzles, world suspense cases, passwords… just to keep her alive.
Relying on her extraordinary IQ, taking logic power as a weapon, and her life as a stake, she copes with a series of fantastic and bizarre events together with a science nerd, Galileo, whose life track somehow intertwines with hers, breaks down unusual criminal tactics and solves various mysteries in the world.
