A Villainous Extra Who Abuses Kids? I Raise Them, Get Cash Back, and Become a Tycoon

[Cashback System + No Romance + Raising Kids + Billionaire Fantasy]

I transmigrated into a book and landed in a living hell from the start! The original owner was a selfish cannon-fodder character who resented her child for being a burden. She abused her three-year-old daughter until the girl was skin and bones, while drowning in gambling debts herself. In the end, she met a miserable fate, her body dumped in the wilderness! The moment I arrived, I awakened the Child-Rearing Cashback System. Loving and caring for my child was the secret to getting rich: every investment earned cashback, and the more I spoiled her, the more I made, with no limit! From then on, I focused on raising my child and making money. No romance, no flirting. I built my fortune step by step: first, saving up a million to escape my desperate situation; then earning ten million to give my child a stable life; reaching a hundred million to establish myself in business; seizing ten billion to dominate the world; and striving for a trillion to ascend to the pinnacle! Toxic relatives trying to leech off me? My money will teach them a lesson! Relatives trying to take my child? They'll pay for it! The book's protagonist looking down on me? I'll slap him in the face with my trillion-yuan fortune and teach him his place! My sweet, adorable daughter clings to me and warms my heart, while wealth keeps rolling in. This once-despised cannon-fodder character, doomed to a miserable death, makes a comeback by getting rich while raising her child, becoming a trillionaire everyone fears and reveres, and reigning supreme!
