[Hoarding for the End of the World] [Infrastructure Maniac] [Decisive Killing] [Heroine] [Rebirth Slap in the Face]
In her previous life, heavy rains flooded the world. She gave up her only piece of driftwood to her fiancé and her best friend, but they teamed up to kick her into the deep sea and feed her to mutant sharks. When she opened her eyes again, she returned to the three days before the natural disaster and bound the "Sea Fortress Upgrade System".
Extreme heat, tsunamis, and acid rain followed one after another, and all mankind could only struggle on floating garbage. While the scumbag and bitch were still fighting over a piece of moldy bread, she was already sitting in a temperature-controlled mobile steel fortress, eating top-quality tomahawk steak, and watching the fully automatic defense tower blast the predators who tried to get closer to smithereens.
When the shadow of the deep-sea monster envelopes the world and the survivors despair, a floating city on the sea that blocks the sky and the sun slowly rises. This time, she not only wants to survive, but also becomes the sole master of this apocalyptic ocean!
