"My Heart Will Not Be Broken" is a fantasy romance + female master and male apprentice + past and present life + sadomasochism novel with deep themes. The cold master Li Heng and the crazy half-demon disciple Shen Jin have been entangled for three lives. In the first life, Li Heng picked up Chen Jin who was wandering in a mass grave, and he died for her to protect her from the disaster; in the second life, when good and evil were at odds with each other, he jumped back to the ruins with her body in his arms; in the third life, Li Heng rescued Chen Jin again and accepted her as his disciple, but he did not know that the two of them were burdened with the fate of the Sky Sheath and the Ash Bones - the Sky Sheath must be destroyed together with the Ash Bones to protect the world. Shen Jin endured his paranoia, and only wanted to protect Li Heng for three lives, and he spared no effort to relieve her bone erosion and waited silently for seven years; Li Heng practiced the ruthless Tao, but during the relationship, his earthly heart was touched, and his Tao heart gradually broke. In the end, Li Heng used the art of returning to the sheath to draw the world-burning fire into his body, and sacrificed himself in exchange for a way out of the ashes. Three years later, he was reborn. The two met again in the snow under the plum blossoms, staying together and breaking the shackles of fate.
