Qing Yue, the heir of a modern eyewear family, traveled across time to Daqi. The moment she opened her eyes, she found herself standing in a public court, accused of being a witch and sentenced to be executed at noon! Everyone mistook myopia for a bizarre eye disease, but only she understood optical optometry. To survive, she used colored glaze to grind glasses to save people, and unexpectedly discovered that a monstrous conspiracy was hidden beneath the Marquis mansion. A pair of glasses can not only let people see the light again, but also illuminate the darkness of people's hearts. She opened the "Qingmu Spectacles Shop", opening the shop while cracking the old case of disaster relief embezzlement, and uncovering the long-standing secret of the heir's mother's death. Seeing clearly the states of the world, and also seeing each other clearly.
