After Time Travel, I Opened a Bank in Dali

I died suddenly in the middle of marketing, and when I opened my eyes, I saw the creditor raising his knife to remove his leg - I am a modern bank collector, transformed into a poor scholar who owes fifteen thousand dollars in loan sharking! Using water traces to calculate the profit, the "child and mother profit" were used, the collector was speechless, and the master of Zhou Mansion robbed the person on the spot! The triangular debt that Zhou Mansion couldn't calculate in 5 days? I crossed my account and compiled a song, and found out a deficit of 80 taels in a long time. The chief accountant knelt down to worship me! The grain farm is in deficit, the victims are running on money, and Yan Shichang has cut off my financial path? I issue IOUs, engage in tool loans, and promote joint guarantee bills. I use modern risk control to build a "private bank" in ancient times! Others rely on force to dominate, I rely on abacus to determine the situation; others seize military power and hegemony, I rely on trust to stabilize people's livelihood! A white note revitalizes the county's economy, and an account is used to strengthen power - the secret treasure of the previous dynasty hidden in the land deed, will it be the final trump card of my financial empire?
