You Don't Want Your Secret Getting Out, Do You?

Yun Kai is a tabby cat with a top-grade cauldron physique that grows stronger through cuddles.

After he dies, his soul wanders the cultivation world for a hundred thousand years, learning countless secrets.

Having suffered enough as a weakling, Yun Kai decides after being reborn that he'll pound people hard and grow stronger by any means necessary.

Xie Yuunian is the greatest cultivator in the cultivation world, the Holy Son of the Heaven-Replenishing Sect. He is invincible, yet frail and sickly.

As Xie Yuunian's cauldron, Yun Kai can only help him live longer by getting stronger himself.

To get stronger (and cuddle), the kitty flips through The Cultivation World's Complete Guide to Secrets. No one with low cultivation, no one who's unattractive.

Dear friend, senior brother, elder, or esteemed lord, if you don't want your secrets exposed, let me cuddle you for a bit.

Only after cuddling his way through it all does Yun Kai discover that every prodigy whose secrets he had gotten ahold of and whom he'd bullied at will was actually one of Xie Yuunian's incarnations.

Yun Kai: Your Highness the Holy Son, hear me out QwQ

Xie Yuunian (sighing): As long as you had fun.

Yun Kai: I wasn't that happy, actually. No, I was super happy...

Xie Yuunian: Our baby can do whatever he wants. Want to keep going?

Both main characters are fluffy animals in their true forms: tabby cat x snowy owl.

The cauldron setup here is that it only works when the receiver absorbs the top's □ fluid. During dual cultivation, the top benefits more than the receiver, who gradually becomes dependent on the top's □ fluid.

The top reached Foundation Establishment at fourteen, so his appearance stopped changing and he still looks like a boy. At the Great Ascension stage he'll grow taller, but won't get more muscular. The receiver won't get more muscular either.

The receiver has split incarnations and is frail and weak-sighted, though that doesn't affect his invincibility. He usually walks the cultivation world through his incarnations. The coercion (?) is basically the two of them playing along to humor a child.

Pseudo-harem. Everyone who has a romantic storyline with the top is one of his incarnations. The author can't write love rival drama, only sweet indulgence. This is a harem story where not everyone is in love with the top.

The main characters are both natives of this world. The one who transmigrates is a supporting male character with very little but important screen time.

Theme: A cat can triumph over fate.
