Countdown to Doomsday: I Rule the World by Signing In

Lin Chen was reborn with ten years of doomsday memories, but the doomsday came three days early. Global power, networks, and communications were instantly paralyzed, and cities fell into chaos and fighting. This time, he bound to the only "Doomsday Sign-in System" in the entire network, relying on his foresight to seize supplies, clear out supermarkets, and occupy top-level safe houses. Through daily sign-ins, he continuously obtains physical enhancement, storage space, defense transformation, alien beast perception and other heaven-defying rewards, steadily building a doomsday fortress. When former neighbors knelt down and begged for a drink of water, when former acquaintances turned into robbers and came to plunder, Lin Chen had already lost all softness - this time, he wanted to personally change the fate of tragic death, rely on daily check-ins, rule the city step by step, and reach the top of the doomsday.
