This is a top-level conspiracy story of "information gap crushing" and "traditional knowledge-based dimensionality reduction attack". The golden finger of the heroine Shen Yunning is not force or foresight, but a special ability similar to "observation of the law of cause and effect" - "Feng Yue Book" can manifest the emotional debt, power debt, and causal debt of everyone in real time. In the context of intertwined personal grievances and the survival of the dynasty, she quietly collects and interprets these debts, and uses the attitude of a "chess player" to gain insight into everyone's weaknesses and weaknesses. The anti-routine point is that the heroine never directly uses force or brute force to break the situation, but uses the "debt of favor" and "debt of cause and effect" that are ignored by everyone to force the opponent into chaos and leverage her strength to make a difference.
