The End of the World: Starting with a Debt of 100 Million

During the global catastrophe, I activated the "Shenhao System", and the balance was linked to the number of survivors. While others were hoarding cans, I opened a commercial center; while others were hiding from zombies, I built infrastructure and opened schools. When the apocalyptic warlords came to the city, I directly opened the system mall: "Don't you just want my city? Come on, I'll make some money first - summon Dongfeng Express, full coverage and strike."
