Su Jingzhe, a modern special operations military doctor, transmigrated his soul into the body of an ancient victim who was displaced due to natural and man-made disasters. It started in hell mode, she was penniless and almost starved to death. But she has no golden finger. Her biggest reliance is her own mind and knowledge as a modern elite. Facing troubled times, she abandoned personal heroism, used modern medical knowledge to treat her companions, used scientific methods to find water and food, used organization and discipline to integrate refugees, and led a group of ragtag people to survive in desperate situations.
The highlight of the plot is the "dimensionality reduction strike": while martial arts masters are still struggling with internal skills and mental methods, Su Jingzhe has begun to promote hygiene and epidemic prevention, establish assembly lines, develop black powder, and use Sun Tzu's Art of War and modern tactics to organize troops. Starting from a wild valley, she built an independent kingdom from scratch that attracted the attention of the entire martial arts world and the imperial court. She doesn't practice magic, but she can use her wisdom and her "special forces" to control the top masters; she doesn't fight for the throne, but she has become the "uncrowned king" who even the emperor is afraid of. This is a powerful story about how knowledge, organization and system can crush personal force.
