The orphan of the Bone Pavilion was destined to be a substitute for the bone, and the Marquis of Zhenbei returned to the capital with the mysterious bone from the border. A game of power with bones as chess pieces quietly began in the deep palace of Beijing.
Su Yanqiu, a female bone substitute doctor, can hold silver needles to revive bones, and can use bones to explore the secrets of the sky. However, because of her life experience, she has become a pawn in the chess game of power. She collected bone letters in mass graves, solved bone riddles in secret chambers, and used her own life to continue the lives of others. However, the secrets hidden in the bone patterns were discovered by Zhenbei Hou Xiao Jinghan - he brought back blood-stained bone talismans from northern Xinjiang, which actually had the same origin as the dark patterns on her wolf fang.
The Queen Mother is seriously ill and needs a bone replacement to survive. The undercurrent in the court is due to the "bone language". The beautiful concubines are making things difficult and the imperial doctors are trying to frame her. Su Yanqiu uses bones to heal people and hide mysteries. While Xiao Jinghan was protecting her from the machinations, he exposed the truth behind her substitute bone. But when the Xiongnu bone talisman was connected to the secret map of the bone pavilion, and when the substitute bone's destiny collided with Zhenbei Hou's spear, they were shocked to realize: Bones can be replaced, but sincerity cannot be replaced; secrets can be solved, but fate cannot be escaped.
Bian Guansha and Jinghua Yue, White Bone Language and Pure Heart, in this bone-led game, will the bone girl break free from her shackles, or will Zhenbei Hou break his destiny? Let's see how half a bone charm and a wolf tooth pendant spell out the answer to "life" and "truth" in the bloody rain of machinations.
