The protagonist has the absolute talent of "photographic memory and automatic cross-reference of data". Faced with the villainous executives' difficulties and massive false accounts, the protagonist transforms into a ruthless rule machine, using the dullest provisions and irrefutable data evidence to reduce the dimensionality of the greedy and sophisticated executives. He refused to give in to hard and soft policies, leapfrogged the hierarchy and fought hard. He cut in from a marginal department and dug deep. Finally, he completely destroyed the corruption network of the entire group and established an absolute system of defense.
