Countdown to Doomsday: I Became Humanity's Savior

I transmigrated to the first day of the apocalypse and awakened the "Savior System."

The System told me that as long as I saved the world, I could return to my old life.

I nodded excitedly, but froze when I saw the mission list:

"Mission One: Make the world-ending villain fall in love with you."

"Mission Two: Get pregnant with his child."

"Mission Three: Kill him with your own hands before he destroys the world."

I looked at the madman destroying the world in the distance and fell into deep thought.
