The evil-spirit male lead, Xiao Ang, is swept into a time vortex and arrives in the Four-Nine City of 1943. He becomes He Daqing’s eldest son, fourteen-year-old He Yu'ang. His soul is unstable, leaving his body very weak. Once, while helping his father cook for the Japanese, he receives quite a lot of tip money. His father hides it on his eldest son, but two former policemen rob them. To save himself, the male lead risks activating his ability. Unexpectedly, he absorbs the policemen’s flesh, blood, and life force. He Daqing has no idea what happened; he only knows that the two men seem to have been eaten by something invisible. He grabs his son and runs home for dear life.
