In her previous life, Luo Lingmeng, the legitimate daughter of the General's household, was a laughingstock in the capital. Beautiful but foolish and naive, she trusted her half-sister Luo Lingyao and her scumbag fiance, only to be poisoned by the two of them working together. They stole her engagement and family fortune, then dumped her body in a mass grave.
As flames consumed her, Luo Lingmeng, an heir to a medical and poison-crafting family in the 21st century, crossed into this world with the "Shadowless" System. Reborn, she shed her foolishness, leaving only icy clarity in her eyes. Pretending to be a wastrel, she carefully navigates the Luo household: she smiles at Luo Lingyao's feigned kindness while secretly setting traps to rip away her hypocritical mask. As for those who betrayed her in her previous life, she cuts off all emotional ties and vows to make them suffer the taste of falling from the heights. Her loyal maid Fuling is her steadfast support, and the silver needles in her hands can both save lives and take them. Her mastery of medicine and poison makes those who underestimate her pay dearly.
The powerful young noble Hua Ze always appears at unexpected moments, his gaze deep and inscrutable. His taciturn servant also helps her in secret time and again. With the System's power, Luo Lingmeng fights her way through household rivalries and court intrigue, rooting out every villain. Along the way, she discovers that Hua Ze's eyes have been following her for a long time. In the end, Luo Lingmeng casts off the trappings of her past and becomes a strong woman who can stand beside Hua Ze. Together, they retire from the world, resting beneath the stars and enjoying the breeze amid mountains and rivers, living a peaceful life free of troubles.
