Rainstorm Apocalypse: Bound to the 1,000x Shrink System (126 episodes)

Twin sisters are reborn back to the eve of a catastrophic torrential apocalypse. The younger sister, Wang Han, snatches the "1,000x Enlarge" system, eager to act as a saintly savior, only to turn around and push her elder sister, Wang Lan—who had supported her for twelve years—into the raging floodwaters to die. Reborn anew, Wang Lan binds herself to the "1,000x Shrink" system discarded by her sister. Cashing out millions and stockpiling massive supplies, she retreats into the ceiling ventilation shafts to construct a microscopic fortress. Slaying giant insects and cultivating fertile crops, she teams up with hardcore engineer Lu Chenzhou to establish a mechanical ecological Eden.
