In a global apocalypse of high temperatures, I built a cold-wind fortress.

In his previous life, Lin Tian had considered his girlfriend Wang Xiaoyuan and his close friend Zhang Qiang as the people he trusted most. Risking his life in the searing apocalypse, he searched desperately for food, only to return to the exclusive mountain retreat and witness their betrayal firsthand. Even more cruelly, they showed no remorse; instead, they pushed Lin Tian toward death in order to survive. When Lin Tian opened his eyes again, he found himself reborn seven days before the apocalypse began. This time, he refused to be anyone's fool or disposable resource. Faced with a girlfriend feigning affection and a greedy, shameless friend, Lin Tian kept his composure while secretly plotting—liquidating his assets, purchasing supermarkets, stockpiling supplies, and upgrading his shelter. Everyone thought he had lost his mind, but Lin Tian knew the truth: in seven days, a blood-red sun would rise, blistering rain would pour from the sky, the city would lose water and power, and order would collapse entirely. Meanwhile, the two people who had once orchestrated his death were still indulging in their final moments of luxury at the retreat. When the air conditioning failed, the food ran out, and all escape routes were cut off, they finally realized that Lin Tian wasn't crazy—he was passing his own judgment in advance. The era of apocalyptic heat had arrived, and the real nightmare was only beginning.
