Jiang He was pushed into a pile of zombies by his sister Jiang Xiaoman and died. He was reborn on the day the system came. The younger sister took away the seemingly powerful solidification skills, thinking that she could become the queen of the apocalypse. Jiang He only got the two auxiliary skills of repeating actions and marking. When the apocalypse came, her sister was trapped in the house due to stupidity and greed, had her legs amputated, and became an experimental subject; Jiang He used auxiliary skills to automatically generate electricity and unlimited material replacement to build an apocalyptic oasis. While his sister was rotting in the quagmire, Jiang He was already standing on top of the ruins, holding the serum that could save all mankind.
