"I saved you from hell, not to make you another devil." When Jiang Yan was six years old, he witnessed his father being shot dead by a drug dealer at the gate of the Public Security Bureau. That memory became an unforgettable memory for him. Twenty years later, he personally rescued the seriously injured undercover Gu Yongan from the drug lair. Jiang Yan is the youngest deputy captain of the Yuzhou Anti-Narcotics Detachment. He solves major crimes and saves his comrades. He is a rising star in the police world. When the clues pointed to a huge overseas drug trafficking group, he tore up the transfer order and dived into the abyss as the doctor "Mo Xing". After three years of being an inhuman undercover, he lost all his identity and almost forgot his own name. They are each other's sharpest knife and most vulnerable weakness. When Jiang Yan chose to go undercover for the second time, Gu Yongan did not dissuade him this time. When the drug lord put the gun into his hand and pointed it at the familiar figure, he realized that the most cruel test is to let the person who saves you push you into deeper darkness with his own hands. "We have all been in the abyss, so we understand the meaning of light better. Even if our hands are stained with filth, we must hold on to each other's last bit of humanity."
