Post-apocalyptic Base Vehicle: I Sign in Daily to Draw Red Alert

Chen Xiao, a college student and livestreamer, transmigrates to the third year of the apocalypse. The world has fallen, zombies roam freely, and humanity survives in base cities. He awakens the "Apocalypse Base Vehicle Sign-in System" at the start, signing in daily to randomly draw red-alert units. On the first day, he receives a fully equipped base vehicle, complete with an armory and resource depot, allowing him to build a mobile city. Isolated and helpless, he is surrounded by hordes of zombies and armies of raiders. Exploring the underground city, he rescues Xiao Hanyun, a female programmer who has faked her death and been reborn. She is aloof and arrogant, but a top-tier design genius, helping him construct a defensive system. Wherever the base vehicle goes, it becomes territory; the sign-in continues, expansion never stops. From one person and one vehicle to a steel fortress, he forges the strongest sovereignty in the apocalypse!
