Ji Shutong personally buried the truth about the fire three years ago, but at Pei Zhaojin's funeral, a videotape sent anonymously blew up his body. No one knew that in the fire that was classified as an accident, a lighter engraved with Ji Shutong's name was hidden among the deceased's belongings. Pei Zhaojin's will points to an abandoned mine, and the man guarding the mine is none other than Ji Shutong, who has disappeared for a long time. When all the witnesses fell silent, and when the police identified him as the only suspect, Ji Shutong stood in front of the tombstone and said softly: "You knew I would come." - He was not here to mourn, but to collect debts.
