The Frail Little Cubs I Raised Can't Possibly Be Max-Level Powerhouses

[1vN + Mild Everyone’s Darling] Only as she lay dying did Su Yi learn that she was merely the villainess fated to die tragically in the book. Her long-lost younger sister, Su Zhao, was the heroine of this world. The heroine was destined to steal her identity, her beast husbands, and everything she had! Su Yi was devastated. But just as she was losing hope, the heroine’s Career System was accidentally bound to her instead. Su Yi was reborn from the ashes, beginning her journey of raising cubs and turning her fate around. “System, am I really going to spend my entire life walking on eggshells and looking after children?” A wolf cub stayed up in the middle of the night, barking from the roof and disturbing the neighbors. A tiger cub rolled around in the grass, then bared its teeth at her. A fox cub led the others in ostracizing the rest of the cubs, ruling the kindergarten like a king. The new little snake was well-behaved, but sometimes looked at her with resentment, and other times with tearful eyes… Then Su Zhao discovered the System had been bound to the wrong person and came to make trouble. The cubs bared their teeth… and suddenly transformed into adult beasts. A wolf howled so loudly it shook the heavens. A million troops of the Northern Night Wolf Clan instantly surrounded the city, kneeling as they asked, “Ancestor, give the word: shall we raze the capital?” A secret command from the tiger brought the entire Southern Red Tiger Clan into action. They all knelt and cried, “War God, give the word!” The fox summoned his blood-related queen. Seeing the army guarding the northern and southern regions appear in the city, the queen was both shocked and furious. “You two marshals, are you planning a rebellion?” The snake rushed into the chaos, seized the white-lotus heroine, and presented her to Su Yi as if offering a gift, letting her decide what to do. Oh, so the soft, adorable cubs she raised were all hidden big shots. … Later, Su Yi would gaze wistfully at the handsome beastmen clinging to her. “…I still miss those soft, adorable little cubs of mine.”
