Jing Ruyi, owner of the doll room, bid farewell to client Madam Li—a moment observed by her daughter Yang Yuanyuan. Yuanyuan recalled her mother's clients: all infertile women who miraculously bore children after receiving Jing's dolls. Yet Jing forbade Yuanyuan from entering the workshop. Fifteen years later, Yuanyuan returned with husband Liang Ze, seeking her mother's help to safeguard her pregnancy. Jing brewed a pitch-black potion, claiming it would protect the unborn child. The moment Yuanyuan drank it, crippling pain tore through her womb. At the hospital, doctors delivered the blow: "The fetus has no heartbeat." During Yuanyuan's recovery, she woke at midnight to eerie humming. Peering into the workshop, she saw Jing cradling a new doll, singing as needles pierced its cloth skin—the same lullaby she'd heard for infertile clients...On the very night her own child died...
