He was once Su Chen, the “God of Death” whose name struck terror into his enemies. But after avenging a comrade, he was branded a traitor and thrown into the Seventh Prison, known as “Hell on Earth.” Its inmates include crime bosses, retired killing machines, and even fugitives wanted by the military. Everyone believes it is a punishment, unaware that it is a top-secret mission: to bring the prison’s underground network to heel and expose a military leaker. During three years behind bars, Su Chen uses his fists to subdue the violent and his golden needles to treat death-row inmates, turning the prison into his own training ground.
After his release, his fiancée humiliates him in public, his family casts him out, and he must face the misunderstanding of a fallen comrade’s widow. But those who mock him as an “ex-con” don’t know that the godfather of the underworld has personally offered him an alliance, military bigwigs are secretly supplying him with resources, and his hands can tear enemies apart with battlefield combat techniques or bring the dying back to life with a lost art of acupuncture. When remnants of the Blood Blade mercenary group resurface and the Gu Group’s conspiracy comes to light, Su Chen will uncover the truth about what happened three years ago and make the whole city pay for once looking down on him!
