Three years behind bars, a name stained with infamy.
Chen Jin walked out of the sunless prison as a murderer despised by the whole city, a discarded son whom the Lin family had trampled at will.
Everyone in Jiangcheng waited to see him fall into ruin and vanish into obscurity.
But no one knew that during those three years behind bars, he had inherited the peerless Ta Su Needle Canon. With its heaven-defying needle techniques in hand, he could command the fate of life and death.
Upon his return to ordinary life, he saved a life with a single needle in the emergency department, astonishing everyone, only to draw the Lin family's frenzied retaliation once more.
Pressure from the powerful, prejudice, and a flood of rumors kept him trapped at the bottom of Jiangcheng society.
He neither fought nor clamored for attention. Quietly establishing himself, he opened an unassuming private clinic that specialized in terminal illnesses and stubborn conditions rejected by major hospitals.
From then on, people from both sides of the law came seeking his counsel, the rich and powerful lined up for treatment, and former classmates who had once looked down on him came to his door on their knees, begging forgiveness.
A wrongful conviction buried for years slowly came to light. Lin Zhixia, who had betrayed him back then, awoke and returned, carrying countless burdens of her own.
With a blood feud on one side and circumstances beyond his control on the other, Chen Jin faced the hardest choice of his life.
The Lin family still harbored wicked intentions and struck back with malice. The charge of practicing medicine illegally, a tidal wave of public opinion, and vicious schemes targeting those around him closed in step by step, determined to destroy him.
His patience and concealment could not last forever. At last, he drew his needle and settled old scores.
Chen Jin unleashed the secret needle techniques of the Ta Su Needle Canon, wielding medicine as a blade. The Lin family members who had done evil were all left afflicted by countless illnesses, suffering the consequences of their own actions.
