Jiang Shuyun personally buried Qi Hesheng in Hanshuang's tomb. At the end of the ceremony, three gentle knocks came from the coffin. Everyone retreated in panic, but he stood there, watching the rotting corpse slowly sit up, with wet blood on his fingertips, and smiled softly: "Did you bury me, or the sin in your heart?" From then on, Qi Hesheng lived, but no longer belonged to the world. Jiang Shuyun was forced to be involved in a supernatural blood contract based on life - the dead were resurrected because of the unatoneable sins of the living. When new "living dead" are born in the city every night, only Jiang Shuyun can hear their heartbeats, and Qi Hesheng is the first and last person to return the sun for him.
