Eighteen years after the end of the world, the earth's surface is shrouded in radiation dust, and humanity's only remaining hope rests on the floating city suspended in the sky. Resources are extremely scarce, radiation sickness is rampant, and crises are everywhere.
Lin Ye, a botanist who has lived alone on the ground for many years, unexpectedly awakened the ability to produce mutant plants. The plants she cultivated not only formed a strong defense barrier, but their fruits also alleviated the pain of radiation sickness.
While being chased by a ground gang, Lin Ye was rescued by Lu Chen, the defense officer of the floating city, and was brought back to the "cloud realm" of the floating city.
Facing the food shortage in the floating city and the threat from external gangs, Lin Ye's ability became the key to breaking the situation. She teamed up with Lu Chen, who was cold on the outside and hot on the inside, to use mutated plants to improve the ecology, strengthen defenses, and treat patients.
In the battles against the gangster "Sand Scorpion" and the radiation storm, the two gradually fell in love and jointly guarded this last home of mankind, writing a legend of green and love that bloomed in the apocalypse.
