Three years ago, Ling Ce, codenamed "Lone Wolf", was a top agent who frightened underground forces around the world. However, due to a fatal betrayal, he secretly retired with half an encryption chip and a scar. He opened a watch repair shop in an old street incognito and became a "down and out poor boy" in the eyes of the neighbors.
Until Su Qingyuan, the president of Qianyi Group, broke into his store with a malfunctioning antique pocket watch in order to trace the truth behind his father's "accidental death" - the pocket watch contained the other half of the secret that matched his chip, and also implicated the shocking conspiracy of betrayal that year.
"Help me find the real murderer. I can give you everything you want." Su Qingyuan's request for help opened up the past that Ling Ce had deliberately kept sealed.
When the killer kicked open the door of the watch repair shop, the former king of secret agents finally awakened: he could subdue the thugs by removing his bones with one hand, use pocket watch parts to decipher tracking signals, and see through the lies of commercial espionage based on his micro-expressions.
From then on, the "poor boy" in the market became the dark blade that stirred up the storm: fighting against the transnational mercenary army, dismantling the power network of hidden clans, and exposing the intelligence conspiracies of foreign forces.
Su Qingyuan gradually discovered that this watch repairman could not only repair the pocket watch, but also repair her broken sense of security; and Ling Ce did not expect that what he was guarding was not only a secret, but also the light for the rest of his life.
When half of the chips were assembled into a complete "blueprint for protecting the country," Ling Ce stood on the roof with a gun, overlooking the brightly lit city: "Anyone who dares to touch me or invade my country will be punished no matter how far away he is!"
