Jiang Mianmian, a modern PhD in criminal psychology, binds to the Microexpression Deity System and transmigrates into the abandoned daughter of a marquis’s household in the Great Sheng Dynasty. The moment she opens her eyes, she’s framed for poisoning her cousin. She coldly exposes the conspiracy and delivers a face-slapping comeback. The System rewards her with “emotional visualization,” allowing her to see through the dark fog surrounding people’s hearts. But as a string of murders and political schemes come to light, she discovers that this transmigration is actually a sacrificial game involving the secret arts of the previous dynasty!
