(Rebirth in the apocalypse + space + multiple heroines + space powers + thunder powers + formation of forces + younger brothers with systems) One of the four gods of war in the apocalypse, Nie Tian, the God of Thunder, was betrayed and poisoned by his subordinates.

Nie Tian: Well, is there a possibility that your shelter is about the same size as several of my villas...
