Recluse swordsman Gong Ruolan hides in a small town running a martial arts school under a pseudonym to guard her family's "Heart-Guardian Sword Manual". Her identity is exposed when she saves Xu Kang, a down-and-out teenager being chased. Determined to avenge his father, Xu Kang insists on becoming her apprentice. From the bickering between the "ice-cold sister" and the "clingy disciple", they gradually get involved in the fog of the old massacre—the mastermind behind Xu Kang's pursuit is actually Gong Ruolan's missing senior brother for years, and Xu Kang's father's death is related to the true meaning of the sword manual: "guard, not kill". When the sword of revenge points to the same sect and the original intention of guarding faces family betrayal, can Gong Ruolan cut through the truth with her sword? Can Xu Kang let go of hatred and understand the true meaning of "guarding the heart instead of killing" in the sword manual?
