During her training, she encountered the young adventurer Sword, who looked just like a middle-aged guy. Worrying about the impertinent, eccentric, pointlessly strong young girl, Sword invited her to go on a journey with him.

This is a story about the protagonist getting the system, going crazy in the biochemical apocalypse, producing aircraft and tanks, destroying zombies, saving good people and killing bad people.
