The old world fell apart in a cataclysm called "Grey Mist Spores", and those infected would transform into terrifying plant-shaped monsters called "Aberrations". Lin Jingheng, a former botanist, lost everything in the disaster and now works as a lone scavenger, struggling to survive on the ruins. With his expert knowledge of plants and chemistry, he became one of the few purifiers able to clean up the "spore zone." By chance, he accepted a well-paid escort mission - leading a small team of people to the legendary safe zone "Aegis Seven". In the team, there is a girl who is taciturn but seems to be immune to spores. This journey of narrow escape will not only force him to face the nightmare of the past, but will also uncover a shocking scam related to the survival of mankind. Aegis is not an ark. Above the abyss, only oneself is the final salvation.
