Billions of dollars in stockpiling: Doomsday begins with nuclear wastewater discharge

Despite international opposition, Xiao Rizi forcibly discharged nuclear waste water into the sea, causing the death of a large number of marine organisms. These dead organisms emitted a large amount of greenhouse gases into the sky, causing global warming, melting glaciers, and rising sea levels. As a result, a prehistoric rainstorm mixed with ancient viruses swept in.
Before Jiang Cheng, who had survived in the apocalypse for three years, returned to the apocalypse, he awakened the apocalypse survival base and stockpiled tens of billions of supplies.
Cut the white lotus, kill zombies, and upgrade the base.
Create a new era in this decadent dark age.
