When the extreme cold came in his previous life, Lu Zheng gave his supplies to his ex-girlfriend and his livelihood to his neighbors. In the end, he was pushed out of the door and froze to death in the blizzard. After being reborn and returning to the thirty days before the disaster, he only did three things: making money, hoarding goods, and closing the building. Steel plates, fuel, medicines, cold storage, and generators were all moved to the top floor one by one; white-eyed wolves, wallflowers, and people who wanted to grab the door were also cleared out one by one. When the city was shut down due to heavy snowstorms, power and internet were cut off, and others were still grabbing the last bite of hot food in the corridor, Lu Zheng had already led Meng Yao to guard the top fortress, setting rules, screening people, and gathering a team. In this life, he doesn't want to be a good person, he just wants to be the one who lives to the end and gets the most.
