On the third day when the red mist swept across the world, order collapsed, zombies ran rampant, and mutated beasts roared and occupied the ruins of the city. The once ordinary girl awakens in a desperate situation with the "Survival Strategy System". Every time a mission is completed, you can unlock supplies, skills or alliance bonds. There is no golden finger of smoothness, only step-by-step caution - she needs to capture the supplies of the abandoned supermarket, crack the mysterious code of the laboratory, win the trust of the survivor team, and hold the bottom line amidst the greed and betrayal of human nature. From hiding alone in the closet and shivering, to holding a long knife to split the corpses; from passively accepting tasks, to actively planning a way to survive, she grew up in the tempering of blood and fire. Faced with the pursuit of evolved zombies, the dilemma of lack of resources, and the wooing and suppression of different forces, she relied on the guidance of the strategy system and her own resilience to gather a group of like-minded partners. They traveled through deserted cities, dangerous jungles, and strange restricted areas, looking for the legendary safe base and revealing the truth about the coming red mist. This is a journey about survival, trust and redemption. Every step is related to life and death. Every choice determines the future. Only those who persist to the end can control their own destiny.
