Repaying Debt to Become a God

Before his death, Guan Zhong asked the system, "How much do I still owe?" The system was silent, then displayed a line: "Forty years." He died. Su Yun crawled out of the coffin, half a mouthful of blood in his mouth, Guan Zhong's jade pendant pressed against his chest, the character engraved on it was not "Su" but "Debt." The system said: 72 hours, 20 taels to 40 taels, execution if overdue. He flipped the silver over, and a character had grown on it, identical to the one on the jade pendant—Debt. His blind sister Su He said, "There's something in your head crying, it's green." Fan Li's bones seeped a tear stain from under the stove. Guan Zhong's eyes were buried beneath the Su family ancestral hall, the same color as that green. Su Yun looked down at his hand, blood from his tiger's mouth dripped onto the silver and was absorbed. He asked the system, "After I pay off this debt, am I Su Yun or Guan Zhong?" The system was silent for three seconds. Then a line of green text appeared: "Whatever you call it, that's what it is." He called it, "Me." It paused, then said one word: "Pain." Open the first chapter and see if he can survive paying off this debt. — Description from novelcodex.org
