A sudden meteorite rain, carrying unknown deadly radiation, destroyed the order of human civilization. Zombies are rampant, natural disasters are raging, and survivors are struggling to survive in despair. Su Wan, a top student in both biology and medicine, struggled to survive in the chaos of the disaster, but unexpectedly discovered that her body had developed a unique ability to resist radiation, and could even faintly sense life energy. What caught her even more off guard was that Gu Jin, her "dead rival" with a mysterious background who was at odds with her in college, was actually trapped in the same shelter as her at the critical moment of life and death.
Su Wan, who has returned from rebirth (with a vague memory that only retains key sense of crisis and fragmentary scenes), relies on her deep understanding of biological knowledge and awakened "life perception" ability to gradually grow from a student struggling to survive to an indispensable "hand of hope" in the shelter in the apocalyptic world where resources are scarce and people are unpredictable. Not only can she treat radiation sickness and delay zombie transformation, she can also identify edible mutant plants and analyze zombie weaknesses.
And Gu Jin, this once cold and distant man with a mysterious background, not only possesses powerful combat abilities, but also seems to know something about the source of this disaster. The old antagonisms become subtle under the pressure of survival. The two had to put aside their prejudices and support each other in the crisis-ridden ruins, from suspicion and temptation to sharing weal and woe. When Gu Jin was seriously injured while trying to protect her and was on the verge of becoming a zombie, Su Wan faced a difficult decision: risk exposing her own secrets and use her yet-to-be-completed healing powers to save this "old enemy", or follow the cruel laws of the apocalypse to preserve herself?
