Doomsday Sky, I Am an F-Class Slave

In the year 2267 of the Old Human Era, it was the forty-third year since the Great Annihilation Catastrophe broke out. The out-of-control seismic gene technology merged with the dark energy material of the earth's crust, giving rise to a global ash breath ecology. Skeleton species that feed on human souls are rampant, and the earth's surface has completely become a restricted area for life. The last survivor boarded the floating fortress "Sky Dome", but fell into a new cage created by the genetic class. Li Fang, a Class F servant, lived in the garbage disposal area for eighteen years. In order to rescue little Ahe, he broke into the upper area and accidentally exposed the adaptability of Jin's Breath, which was strictly ordered to be killed by the Holy See. Step onto the surface cursed by eternal punishment, and in the struggle between the fangs of the Corroded Skeleton and the hegemony of the sky, step by step, you will uncover the truth of the catastrophe and the ultimate secret of the Fire Plan. In the choice between destruction and symbiosis, you will find new life for mankind in desperate situations.
