[Parallel world + system + apocalypse + ability to survive + decisive killing + safe house to store explosive materials]
Ye Junrui accidentally traveled to a parallel world due to an electric shock.
Nuclear wastewater has polluted large areas of land,
Poverty and plague spread, and endless wars decimated the population.
Human beings live in the dark corners of the world,
The home they once lived in has become a gathering place for all kinds of strange species.
Ye Junrui said calmly
"This is nothing~"
