Lin Xiao appears to be nothing more than an ordinary food delivery boy. In reality, he is the “North Wolf,” one of the most feared operatives in a top-secret organization. When classified intelligence is leaked and threatens to destroy everything, the organization’s Patriarch urgently summons Lin Xiao and his senior sister to the city of Longcheng to uncover the traitor within their ranks . To move undetected, Lin Xiao hides his true identity and works as a delivery driver, answering the call of duty while keeping his legendary past buried .
His mission takes an unexpected turn when he crosses paths with Qin Sihan, the eldest daughter of the Qin family. Once the most gifted member of her generation, Qin Sihan has been sidelined by a family that favors sons over daughters, leaving the once-proud Qin clan on the brink of collapse . Her only remaining value to them is a forced marriage to Yan Tianyu of the powerful Yan family—a union that could save the Qin family from ruin .
When a high-stakes bidding event becomes the battleground between Lin Xiao’s targets and the Yan family, the “lousy delivery boy” steps out of the shadows. The Yan family opens with a bid of eighty million, and the room assumes no one would dare challenge them. Lin Xiao calmly raises the bid to one hundred million, humiliating the Yan family in public and making himself their primary target .
As the conspiracy deepens, Lin Xiao discovers that the traitor he is hunting and the forces destroying Qin Sihan’s family are connected. Now, the North Wolf must protect the heiress, expose the mole inside his own organization, and dismantle the corrupt powers of Longcheng—all while the world still sees him as nothing but a delivery boy .
