{Easy + Time Travel + Social Animal Counterattack} Jin Abacus owes Heaven tens of billions of merits, and it is only natural that he should work to repay the debt. As a result, the style of the world of immortality suddenly changed: shared flying swords, merit takeaways, ancient god incense funds, credit score rankings... He used financial leverage to make money. From building a regional credit system, to issuing "causal hedging" products, and even exploring the remains of ancient wealth and silk, Jin Abacus used an abacus to turn the entire world of immortality into his large-scale financial experimental field on the ridiculous journey of starting a business and paying off debts. Of course, there is always a "powerful" assistant like Wang Wu, who constantly uses his weird ideas and talent for getting into trouble to add countless jokes and "surprises" to this journey of financial immortality.
