The Poison-Handed Immortal Doctor: Your Highness, Please Behave

Leng Yue, a top modern poison doctor, transmigrates overnight and becomes the mistreated illegitimate daughter of the Marquis of Anyuan's household. From the start, she's on the brink of death and bound to an unreliable "Kiss of the Soul" System. Want to stay alive? Share a passionate kiss with a woman blessed by fate within three months, and copy her abilities!

Her target is Xiao Lingyan, the powerful Grand Princess who holds sway over the court. Leng Yue grits her teeth and lunges at her, but only just brushes the corner of her lips. A piercing mission failure warning sounds, and Leng Yue collapses from exhaustion.

When she wakes, she hears the lofty Grand Princess gently touching her lips and murmuring playfully, "That tasted nice. Shall we do it again?"

From then on, Leng Yue's life veers completely off course. With silver needles in her left hand, she saves lives; with deadly poisons in her right, she takes them. The name "Poison-Handed Immortal Physician" shakes the capital. In the Princess's residence, she spends her days and nights with the aloof and noble princess. Between the mingling notes of their zithers and flutes lie careful tests at every turn, and a surging attraction.

But the treacherous court will not let her stay out of its affairs, and one vicious assassination attempt follows another. As the mastermind emerges from the shadows, and true affection becomes impossible to distinguish from calculation,

Leng Yue takes the Grand Princess's hand and gazes toward the boundless world beyond the palace walls:

"Your Highness, the capital is only the beginning."

"Our world is vast."

This is a legend of two women joining forces to rule the realm, with a kiss as their pact and medicine and poison as their blades.
