Doomsday SurvivalNo VirginNo Brainstorm
In 2045, global high temperatures are out of control, with surface temperatures exceeding 50°C.
The day the underground city closed its entrance, 30,000 people were left on the verge of death.

[Civilized backup system enabled]
No supplies, no bases, no reinforcements.
The system does not give him answers, only the knowledge that humans once had.

The underground city thinks the surface is dead.
They don't know——
It is not ruins that are abandoned.
It is the place where human civilization begins again.
