In the twenty-third year of the Republic of China, Lin Zhiyuan returned to Mo Township in the south of the Yangtze River to investigate the cause of death of his parents. The cinnabar mole on his left eye had a strange resonance with the Mohist secret treasure "Mo Soul Pearl". The young master of the Mo family, Mo Yanzhi, looks as gentle as jade and secretly helps her investigate, but he doesn't know that the other half of the bead is hidden in his right eye. When the two uncovered the truth about the mining accident twenty years ago - Mo Yuanshan killed thirty-seven miners and Zhiyuan's parents in order to refine the immortal blood ink, fate had reached a dead end. Zhiyuan gouged out his eyes and destroyed the pearl, and died together with Mo Yuanshan; Yanzhi jumped off the cliff with his blood-stained guqin in his arms, leaving only a handful of ink ashes condensed with blood and tears. It turns out that the most poisonous curse is the unfinished sentence he said when he was young, "We are born in the same quilt and die in the same hole."
