The System Era begins, and eighteen-year-old Lin Cong awakens what appears to be an ordinary Basic Settlement System. While everyone else makes a name for themselves with their exclusive abilities, he runs, studies, and helps friends complete missions, yet can only accumulate a string of tiny numbers. During one challenge, he decisively admits defeat, only to discover that his system can settle not just outcomes, but also processes and rules. Su Wan, Zhao Ye, Zhou Cang, and other companions gradually join him. Strange check-in locations, unreadable secrets, and abnormal system records slowly come together to form a single mystery. What other abilities does the chibi system standing on Lin Cong's shoulder, which insists every day that it only knows how to calculate accounts, secretly possess?
