A Dependable World-Saving System

In the apocalypse, I, Sun Yun, gaze upon miles of ruins without fear. It's not because I have an apocalypse-level wife, nor because I have a planet-destroying daughter. I'm simply confident in my own strength.

(What! Someone with a System has to live off their partner?)

"System loaded. First world locked!"

"Beginning rescue plan."

"Host: Sun Yun"

"Gender: Male"

"Aah!!! Stop with the introductions! The building's about to crush me! System, can I count on you or not?"
