Doomsday Game: Buy the whole world from the subway station

[Survival in the Doomsday + City + Upgraded Hideout + No Female Lead + Decisive Killing + Survival in Disasters]
The Doomsday Game is Coming.
Disasters are happening all over the world.
Volcanoes, earthquakes, floods, extreme heat, viruses, severe cold.....
In just half a year, the population of the entire Blue Star has dropped by 80%, and civilization has almost collapsed.
Humanity has no choice but to enter the Doomsday Game to challenge survival in order to gain hope of survival.
Fortunately, Tang Yu awakened the [Super Monopoly] game plug-in.
So he started from [Subway Station] in the Doomsday Game World and bought the whole world.
Buy [Subway Station], get a hideout, kill refugees, and get some loot.
Buy [Red Romantic Club], kill the evil god believers, and get rare construction drawings.
Buy [City Center Hospital], open a medical station, and refresh medical supplies steadily every day.
………
When everyone is still working hard for the next disaster and trying to survive.
Tang Yu lay in a hideout full of supplies, looking at the asset projects scattered all over the map and thinking.
"Which investment project should I inspect today?"
