Everyone's Castle: Choose the Weakest Catgirl from the Start?

Everyone is reincarnated into another world, where each person gets a castle and an altar. The altar refreshes every day.

Xuan Hui looked at the altar:

Catgirl: 1-star aptitude

Frost Troll: 3-star aptitude

Royal Griffin: 5-star aptitude

Armored Earth Dragon: 7-star aptitude

Aptitude determines your potential.

Which one should he choose? Is there even a question?

Of course, the catgirl!

Is it because she's soft-spoken, delicate, and easy to push down?

Of course not.

It's because my unique hidden talent, Infinite Upgrades, has awakened.

All summoned beasts ignore aptitude restrictions

and can level up without limit.

"What? A Frost Dragon was killed by Boss Xuan Hui's catgirl?"

"What? A Golden Behemoth can't beat Boss Xuan Hui's leopard girl?"

"What? Boss Xuan Hui, supposedly the strongest, has a castle full of animal-eared girls?"
