Financial genius Lin Fan, with the memory of a top trader, has passed through the world of cultivation as a handyman of the Black Iron Sect. Here, the strong are respected and resources are monopolized. Lin Fan backhand used K-line charts and compound interest formulas to securitize contribution points, turn the weapon refining workshop into an assembly line, use "risk hedging" to resist the beast tide, and use "short selling" to destroy the enemy sect. When the giants of the Immortal Alliance were surrounded and suppressed, he smiled slightly: "Everyone, have you ever heard of... The sect's debt-for-equity swap?" A dimensionality reduction attack that used financial rules to subvert the order of cultivation began.
