Cashback: My Life of Freedom

Wu Feng is treated as a money-making tool by his wife and daughter, receiving only a thousand yuan monthly allowance. When he faces a heart attack, they refuse to sign and accuse him of fraud. He endures being kicked out of meals and a dog-soiled bed, living worse than a pet. After awakening a ten-fold cashback system, he turns the tables, making his family suffer the consequences while he becomes a wealthy philanthropist.
