She is the knife lurking in the darkness, and he is the shield walking in the sunshine. Investigative reporter Lin Wan pursues the truth behind his father's "suicide", but ends up in a dead end. In a desperate situation, the man who left without saying goodbye three years ago suddenly appeared and dragged her out of the devil's cave with one against ten - Qin Feng, the former ace of the "Blade" commando team, now a cadre in the village, and her ex-boyfriend.
"Qin Feng, you can't afford to wade in this muddy water."
"I will avenge you. I will protect your life."
From the impoverished mountain villages where they were distributed, to the border towns lined with drug manufacturing factories, to the abandoned mines where genetic weapons laboratories are hidden, every step is a dead end. She uses her pen as a blade to uncover the hypocrisy of the evil forces; he uses his body as a shield to shatter deadly murderous intentions one after another. She is his lost and recovered weakness, and he is her sharp blade that helps her survive from desperate situations. However, when the veil of the conspiracy was lifted layer by layer, they discovered that everything was far from what it seemed - a transnational criminal group, a genetic weapons program, and a top-secret file codenamed "Nirvana." On the file, her name is "Perfect Carrier", and his name is clearly written as "No. 017: Best Living Sample".
"Qin Feng, what they want is not the USB flash drive, but you."
"Then it depends on whether they have the life to take it."
This is a love that walks on a knife's edge, and it is also a last-ditch battle to defend the homeland. When the war breaks out on the border again, he will use the iron-blooded methods of the special forces to eliminate the monsters. She will use the professional belief of a reporter to uncover the truth. The couple join forces and thunder strikes.
