Everyone's Airship Survival: I Upgraded Alone on Land

DisasterPollutionSevere ColdHigh TemperatureSurvival for All Different disasters have occurred on each continent, and the entire population has fled to the sky to survive. While others are still fighting for a little profit in the sky, I have unlocked the black carriage that isolates pollution and can drive smoothly on land alone. Mutant mice? Go out and work for me! Doll maid? Go out and work for me! Do it yourself? Doesn't exist. Letting others do the work for you is the way to get rich~ I am the night watchman, I am the champion of the great game!
