The heroine is bound to a rare "parasitic reverse system", which is parasitic on a truly systematic "old enemy". The old enemy's "Justice System" issues tasks to suppress the heroine, which will consume the old enemy's "luck value" as a price, and this part of the luck value will be collected by the heroine's reverse system to exchange for wisdom and ability. The heroine cannot directly resist the system's instructions, because the system will forcibly reduce her IQ or luck; but she can take advantage of the system's "logical loopholes"-deliberately making the enemy's mission "successful" but with a reduced effect, or leading the enemy to do things that "harm others but not benefit oneself" to accelerate the consumption of his luck. On the surface, the heroine is the "crushed Cinderella", but in fact she is the "mastermind behind the big boss". As her old enemy becomes stronger step by step, she wants to steal all his foundations until the last moment, and let him knock down his building with his own hands.
