I Sell Lifespans in the Mortal World and Somehow Married a Sword Immortal

My name is Lin Yuan, and I sell lifespans.

My customers range from national academicians to stray cats on the street. Fair deals, no one gets cheated.

I picked up my wife. She's lost her memory and always thinks she's a cosplayer. She's especially delicate.

Until one day, a group of strange people calling themselves “Heavenly Demons” came looking for trouble.

I was just about to bring out the System when I saw my “delicate” wife slice the top off a mountain with one sword strike.

She turned back, tears in her eyes. “Don't be afraid, honey. I'll protect you!”

I looked at her, then at the System.

Uh-oh. Maybe neither of us is normal?
