In order to fulfill her grandmother's last wish, Su Wanqing, a doctor of botany, plunged into the Miao border in the 1980s to study a mysterious companion herb.
Unexpectedly, when he first arrived, he mistakenly entered the restricted area and was caught as a suspicious person by Lu Yanxing, the youngest and most unkind "King of Hell" stationed there.
He is a walking hormone, the embodiment of discipline, a frontier battalion commander that everyone respects, and everything is silent wherever he looks.
She is a beautiful and intelligent female doctor, with a silver needle in her hand that can save people, a clever mouth that can irritate people, and a body full of thorns that is also fragrant and charming.
Everyone in the compound was spreading the word that what bothered Commander Lu the most was delicate "city girls" like Su Wanqing.
But no one knew that for countless late nights, Lu Yanxing could not sleep because of her, and he rubbed the armband that she had bandaged until it was hot.
Until one mission, he held her tightly in his arms and breathed deeply into her ears: "Su Wanqing, you are not only good at medical skills, but you are also good at killing people... My life."
She raised her head in his arms, tapped his Adam's apple with her fingertips, and said with charming eyes: "Commander Lu, will you give me this life?"
