The soul of a modern financial elite is transformed into the son of a run-down earl in ancient times, and discovers that the civil and military officials of the entire dynasty, including the aloof prince, are the "laoba" of his family. So, holding the ledger in hand, he transformed into the dynasty's strongest creditor and embarked on a journey to subvert the traditional power game using economic principles.
Intention: Using "finance" as the sword and "economy" as the shield, build an unprecedented dimensionality reduction and strike-style conspiracy story.
