Qin Chen is the last inheritor of the hidden medical practice in the mountains. He was adopted by his master at an early age and learned the peerless ancient silver needle method. Now his master has disappeared mysteriously, and his sister Qin Xue is suffering from a rare and mysterious poison and is dying soon. He is forced to go down the mountain alone and break into the bustling city to find the antidote to prolong his life.
He used his incredible silver needle technique to save Lin Wanqing, the daughter of a top wealthy family who was suddenly critically ill and dying at a hospital in the city. This shocked the city's medical community and accidentally uncovered the Lin family's secret conspiracy to test taboo life-extending secret drugs on humans. His sister's incurable disease happened to be from the same source and closely linked to the evil poison.
On the surface, the head of the Lin family expresses gratitude, but behind the scenes, he plans every step of the way to coerce and lure Qin Chen, hoping to forcibly control Qin Chen for the family's use. Internal strife breaks out within the Lin family as the legitimate concubines seize power, and the villains of the second family collude with external capital forces to covet tens of billions of family assets and secret medicine formulas. Qin Chen instantly becomes a key pawn that all parties are vying to win over or get rid of at any cost.
At the critical moment when his sister's condition worsened rapidly, Qin Chen followed the clues about the antidote and gradually uncovered the past: his long-lost life experience came to light. His biological father was the pioneer in the development of the first secret medicine who was cruelly silenced by the Lin family. Even his master disappeared for no reason many years ago, and he was all involved in this old bloody case.
Faced with the threats of the rich and powerful, the bloody siege by capital, and the approaching death of his sister, Qin Chen is caught in a dilemma: compromise and rely on power in exchange for a chance of survival for his sister, or risk everything to uncover all the dark truths, avenge his father's generation, and destroy this prison of man-eating capital. In the end, he resolutely entered the world with a silver needle in his hand and established himself as a medical practitioner. One needle can save lives and save the world, and one needle can also suppress evil spirits.
