通古今后，我养成了未来奸相

About

Modern-day student Su Jin discovers that a mysterious ancient scroll links her to the past, allowing her to exchange items with Shen Yubai, a frail young noble living in the long-lost Dayue Dynasty. When Su Jin learns the dynasty was destroyed by a future treacherous prime minister, she asks Shen Yubai to help stop the coming disaster—unaware that he may be the very man fated to change history.
