Tian Bing, on the surface, looks like an ordinary young man that no one cares about, but in fact he is a top forensic doctor hidden in the market. He is also a mysterious boss who can single-handedly stir up the black and white. His cold and restrained eyebrows hide an aura of calmness and self-reliance. He has never said many harsh words. In order to repay his upbringing, he was forced to marry a wealthy heir who was rumored to be ruthless, bloodthirsty and suffering from a hidden disease. He wanted to fulfill the agreement in a low-key manner, but unexpectedly he was involved in a series of murders as soon as he entered the wealthy family. The murderer pressed forward step by step and made plans one after another in an attempt to drag him into the abyss. As the murders were uncovered layer by layer, Tian Bing was forced to take off his disguise, and the hidden vests were exposed one after another. Forensic doctors, hackers, fighting masters, underground power leaders... Among the vests, he started a life-and-death contest with the murderer. Under the cold shell, there was a passionate revenge and protection. In the process of solving the murder case and slapping the villain in the face, Tian Bing continued to grow. Not only did he uncover the real culprit behind the scenes and avenge his past grudges, but he also found his own way to become a strong man in a desperate situation, turning his forced substitute into a master who controlled the overall situation.
