Qin Chuan, a retired special forces soldier, was once a top first responder in the war zone, codenamed "Blade". After being discharged from the army, he retired to the public life and became an ambulance doctor.
Possessing the "nine-needle life-sustaining method" and relying on battlefield first-aid instincts, he can pull back the dying in the thin line between life and death.
There are undercurrents in the city: rogue doctors are selling organs, drug lords are using medical channels to transport drugs, and high-level corruption in hospitals is covering up their scandals.
He saves lives and heals the wounded, and also uses the hands of a healer to administer the punishment of a king.
There are no superpowers, only hard-finished medical intuition and iron-blooded instincts.
Visiting doctors again and again, they uncovered layers of conspiracies and got acquainted with reporter Pei Ran, forensic doctor Shen Qingwu, and veteran military doctor Chen Shoushan.
When the emergency light turns on, he is not only a doctor, but also a soldier who tears through the darkness.
