After being brutally stabbed in the back by his senior brother, Shen Guiyan was deprived of his cultivation and thrown into a mass grave to die. When he was about to die, the silent Baishi Karma Needle in his body suddenly awakened. The inherited spirit Qin Huai appeared and gave him a cruel death order: he must save the person within seven days, otherwise he will die suddenly.
But an even more horrifying truth followed - everyone he saved was the enemy who would personally massacre the Shen family and dig up his ancestral graves a hundred years later! Retrograde acupuncture saves one person's lifespan at the expense of one's own lifespan, and creates a group of enemies who will take their lives in the future. This is actually the death that he himself dug up a hundred years ago.
Death row prisoners, wealthy daughters, and sect bosses have become his treatment targets one after another. Weird heart-eating poisons, century-old causal lines, and secrets of forbidden areas have emerged one after another. His former sectmate Xie Yuan is pressing closer and closer, and all forces are eyeing him. After the eye of cause and effect is opened, memories of killings a hundred years ago and grievances and reincarnations continue to emerge.
Saving people is to save lives, but it is also to dig one's own grave; to resist fate, but also to face the crisis of world collapse. Shen Guiyan is trapped in a closed loop with no solution. While using counter-heaven acupuncture to walk around the edge of life and death, he is also dismantling the shocking trap set by his previous life. When saving people turns into raising enemies, when destiny turns into a prison, he can only go in reverse direction and overturn this chess game of cause and effect that spans a century!
