So What If I'm a Low-Rank Fuzzy? I'm Unstoppable!

[Aristocratic academy + raising fluffy pets + 1vN + a true drama queen + secret identities] Ding Fu was found in a slum. Her adoptive parents and sister, none of whom are related to her by blood, all have top-tier spirit pets and enjoy boundless glory. But at the academy, she is assigned a low-tier, arrogant Pallas's cat. Everyone says that even if she has good grades and gets into the aristocratic academy, her poor aptitude means she'll never amount to anything. Only she knows who switched her spirit pet, but she doesn't care. In her previous life, she was the first person to tame a spirit pet, and the only one who understood that once animals became spirit pets, they turned into bloodthirsty demons. She used her own methods to stop them from slaughtering humans and pioneered the use of spirit pets in the fight against the insect race. Unfortunately, the heavens envy the talented. She perished in a battle, but in her next life, she was born in a slum with all the memories and aptitude of her previous life, then taken in by the Ding family. Ding Fu keeps a low profile in the Ding family, waiting for the day her aptitude fully awakens. When the real heiress returns, she is blamed for every kind of “crime” and targeted by everyone. They think she's nothing but a joke, putting on a show for attention. They have no idea that her cool-headed, soft-hearted fiancé is willing to offend the powerful for her; that her refined, gentle upperclassman, who was born into the same circumstances, protects her at every turn; that the unruly yet pure-hearted royal bastard is completely in her palm; that the handsome, noble prince from a neighboring kingdom keeps pursuing her; even the steady, reliable military commander makes exceptions for her again and again... At this point, no one knows that the key to defeating the insect race is hidden within her.
