Protagonist: Lin Mo, an ordinary social worker in modern times, stayed up late and died suddenly while wearing a book.
The background is set fifty years after the "Catastrophe", where radiation dust, mutant creatures, scarcity of resources, and the law of the jungle are the norm. There is a huge class divide between those with awakened powers ("Awakeneds") and ordinary survivors ("Refugees").
Identity in the book: The original owner "Lin Mo", a cannon fodder passerby who was brutally killed by the villain's little boss after appearing in the original book for three chapters. Identity: An ordinary doctor (with mediocre medical skills) located in a small settlement outside "Rust City". Under extreme fear and desire to survive, Lin Mo activated the "Survival Evolution System".
System core functions:
Basic scan: Scan the target (creature/item/environment) to obtain basic information (name, status, threat level, etc.).
Survival Points: Obtained by killing enemies, completing tasks, exploring unknown areas, and achieving specific achievements. Survival points are the "currency" of system functionality.
Skill tree: Spend survival points to unlock/upgrade skills. Initial skill tree branches: medical specialization (from basic bandaging to surgery), fighting instinct (improving melee reactions and skills), environmental adaptation (improving resistance to radiation, toxins, etc.), And basic manufacturing (using waste materials to make simple tools/weapons). More branches can be unlocked in the future (such as superpower guidance, mechanical engineering, biotechnology, etc.).
