Ji Jin was abandoned since he was a child, but was adopted by a mysterious man in a dark alley and grew up to be a cold-blooded murderer. He didn't know his life experience, he only knew that the blade in his hand danced only for the end. Until one day, he was ordered to assassinate a low-key wealthy businessman, Shi Lin, but he saw in the other person's eyes the jade pendant he had worn when he was abandoned twenty years ago. Shi Lin, this businessman who was as gentle as jade and held half the city in his hands, actually looked at him with an almost doting gaze. When the blood and fire revealed the truth, Ji Jin was shocked to realize that the man who had used his body temperature to warm his frozen fingers was the adoptive father he was most unwilling to acknowledge in his life.
