Doomsday Tycoon: I Buy the Entire City With a Wealth System.

Global catastrophe descends as a Doomsday Game envelops Planet Blue! Volcanic eruptions, earthquakes, floods, extreme cold, and deadly viruses run rampant across the world. In merely half a year, eighty percent of humanity perished, pushing human civilization to the brink of collapse. Faced with absolute despair, humans are forced to enter the Doomsday Game to survive, obtain vital supplies, and sustain the last spark of mankind. After transmigrating into this apocalyptic world, Tang Yu awakens a one-of-a-kind god-tier plugin — the Supreme Tycoon System, shattering the cruel rules of doomsday survival! While ordinary survivors struggle desperately against natural disasters and ferocious looters, fighting tooth and nail for trivial resources, his exclusive system becomes his greatest reliance to reverse his fate and dominate the end times. He spawns in a ruined city inside an empty, completely looted convenience store, surrounded by lurking dangers, rampant exiled scavengers, and impending catastrophic disasters. With forward foresight and the blessing of his system, Tang Yu seizes a subway station and transforms the sturdy, concealed underground space into his first safe haven in the apocalypse. Ruthless and decisive, he eliminates roaming looters and harvests massive rare spoils, laying a solid foundation for his early survival. He gradually expands his territory, taking over core city landmarks one after another. He seizes the city central hospital and builds a professional medical station that stably refreshes rare medical supplies every day, completely solving the extreme shortage of medical resources in the end times. As his territory levels up and his influence expands endlessly, Tang Yu breaks free from mere basic survival and uncovers the world’s deepest secrets. He unravels the buried past of the ten major laboratories, witnesses the millennium conflict between calamitous abominations and newly born gods, and sorts out the intricate disputes over worldly authority and subordinate factions.
