Lin Yi, 26 years old, is a "collection expert" in modern society, but he has a kind heart, adheres to the bottom line, never violently collects debts, and specializes in "psychological tactics." He accidentally traveled to a parallel world and became the creditor of a top rich second generation... The original owner was a spendthrift who lent out tens of millions with a lot of IOUs. As a result, he died in a car accident and left a pile of bad debts to Lin Yi who came through time.
