The Yun Family's Ninth Child is an Imp! - Chapter 7082, I believe

The person that Pei Zhen hates most in his life is the perfect Fu Sichen. Alas, life is full of surprises and unpredictability. One fine day, an accident turns Pei Zhen into Fu Sichen’s pet cat! As Fu Sichen’s pet cat, he makes a shocking discovery about his sworn enemy – a deep dark secret that the perfect Fu Sichen has kept hidden for years. Trapped in his cat body, Pei Zhen moves from one adventure into another while trying hard to find a way of turning back into his human self. When he finally does, the world as he once knew, has become a completely different place!

By the time I realized it, I had reincarnated into another world.

I kept sleeping, and at some point I became a Demon Lord.

Even though I never wished for it.

But for me to not have to work, this world is the best. It must be true that good things happen to good people.

The flavor of Sloth is as sweet as honey. Glory, diligence, virtue, or honor. I have no interest in anything like that.

What’s there to hide? The Lazy king is… none other than me.

Whoever refuses to accept, come fight!
