My Ex-Wife's Doomsday Fortress

A global extreme cold disaster descends. In her past life, Su Qing was betrayed by her ex-husband Gu Cheng and his mistress Zhou Fang, who drained her blood and left her to freeze to death. Reborn 90 days before the disaster, she decisively caught them in the act, filed for divorce, and went on a shopping spree to liquidate her assets. She built an impenetrable steel fortress with natural geothermal heating in the suburbs, stockpiled millions in supplies, and adopted a giant battle pet named "Mimi." After the extreme cold arrived and social order collapsed, Gu Cheng turned into a villainous gang leader and attempted to seize the fortress. Relying on its strong defenses and her combat prowess, Su Qing wiped out the thugs and watched coldly as Gu Cheng and Zhou Fang killed each other in their desperation, turning into ice sculptures, ultimately welcoming a true new beginning in the apocalypse.
