One month before I was reborn in the apocalypse, I bound the "Doomsday Goddess Strategy System".
As long as you increase your favorability, you can exchange for black technology weapons and survival resources.
I found those all-powerful queens, valkyries, and female scientists in the future in advance.
Sending warmth to them when they are most vulnerable - compressed biscuits, antibiotics, or even just a word of concern.
Watch them go from wary to dependent to enamored.
When the apocalypse comes and others are struggling among the zombies, I have already started a leisurely journey to the apocalypse with my mobile fortress and a car full of beauty.
It's just... Why are these strong women who are supposed to be hostile to each other looking at each other more and more wrong?
