The cold-blooded master of the sword technique, who never survived after thirteen needles, is known as the "Yam Luo Sword"; and Qi Hui is the only forbidden doctor who can defy fate and survive under his needles. When the hidden serial murder case in the hospital points to the operating room, every injection by Li Jue is like carving a death contract, while every injection by Qi Hui is tearing apart the truth. They are not partners, they are rivals. Only they know the pinholes that were not marked on the autopsy report and the dates that were erased from the medical records - those patients who died of "natural death", by whose hands they died, and by whose forbidden magic they lived. This secret battle between medical skills and conspiracy never relies on redemption, but only on life for life.
