My name is Lin Xingyu, and I used to be called "The World-Destroying Demon Lord".
Current life goal: save enough for a pension and retire peacefully in this world.
I successfully joined the National Special Case Investigation Department and received generous benefits including five insurances and one housing fund.
The only problem is—my immediate boss, Huo Jianhua, is the supreme Martial God who was my mortal enemy who sealed me away thousands of years ago.
Today, he is a cold-blooded social beast who worries about KPIs and mortgage loans, and I am his new civilian employee who "fights the five scum".
We pretended not to be familiar with each other during the day, and worked together to deal with S-class supernatural disasters at night.
They work together so well that it's like they've never been apart.
Until one mission, I used my original magic power to save him.
He pressed me against the wall, his breath hot:
"Is it fun to pretend to be a newbie?"
"... I have been looking for you for ten thousand years, Lin Xingyu."
