Natural disasters occur suddenly in the last days, and the global order collapses. Su Jin, a female embalmer who was despised by her relatives and shunned by others, relied on the extreme calmness, anatomical knowledge and chemical reserves given by her profession to build the strongest fortress in a wasteland where everyone was desperate. The story unfolds from the unique perspective of the heroine. What is exciting in the early stage is that she uses her professional knowledge to accurately hoard supplies, renovate houses, and coldly rejects the best relatives and neighbors who once bullied her, forming a strong contrast between before and after. In the middle period, she rescued the seriously injured male elite soldier. From suspicion to joining hands, the two formed a survival team and established a new order in the wasteland. They outsmarted various gangs and careerists who had lost their humanity. They farmed, built infrastructure, and developed forces, experiencing a post-apocalyptic "era novel"-style survival and reconstruction. In the later period, facing more severe natural changes and threats from huge hostile forces, the protagonist group led the people to carry out the "Great Migration", and finally established a stable cornerstone of the new world, completing the sublimation from individual survival to the continuation of the fire of civilization. The full text has no special abilities or systems. It focuses on the heroine's IQ, professional skills and decisiveness in killing. It has dense points and a tight rhythm.
