I’ve Lived for 100,000 Years, and Now My Junior Sect Sister Is Forcing Me to Marry

First-person + invincible protagonist + nurturing + cultivation

The junior sister my sect took in has forced me to marry her.

With her hands on her hips, she stands on the jade marrow greens I've spent three years carefully growing and threatens to rip them all up and feed them to the dogs behind the mountain if I refuse.

I have a bit of a headache.

After all, this girl doesn't know that I watered those greens with the Immortal Spring. One stalk can add ten years to an ordinary person's life.

She also doesn't know that I'm no mere janitor, but the venerable ancestor who has guarded the sect for a hundred thousand years.

Just as I'm about to knock her out with a stalk of greens and wipe her memory, she suddenly points at my sleeve, her eyes shining like stars. “Stop pretending, Ancestor! The ancient runes on your sleeve are exactly like the ones in that tattered book I found when I picked you up!”

My heart sinks. It's over. I forgot to replace the protective charm I casually drew a hundred thousand years ago when sealing the Demon Lord.
